List 1a tyres
First post on here so Hello everybody.
I was hoping you chaps could give me a bit of advice on List1A tyres which I have to use for the class of racing I'm about ot embark upon. Car is a sevenesqe dax rush weighs about 680ks with about 280rwhp. Someone mentioned T1-Rs shaved to 4mm are pretty good and close to 888 type performance. Any advice appreciated. Cheers, Bob |

Scrubbed T1-Rs are good but NOT close to 888 performance. Your best bet is to see what tyres the top ten cars in your intended class are running on.
I don't think you would go far wrong with scrubbed T1-R's. On a light kit car I would go as low as 3mm, I use 4mm on my 840Kg saloon and they can last a season! |

Depends on what size you're running - I believe that Scudo (?) Stunners are currently the tyre to have in 13" - before that it was Bridgestone RE270s, if you can still find them
What ever you chose, you're going to have fun getting 280 ponies down through 1A tyres Why don't they just call it the pants tyre list (1A) and the good tyre list (1B) |

Don't be. Many championships mandate tyres such as the Dunlop Formula R which, although an excellent and pretty durable tyre, cost about £100 each. It is the single reason I am not doing the series my car is intended for. Daft.
I'm sure any tyre that would give the kind of performance needed to make the very best of your 280 BHP would be highly expensive and unlikely to last very long. This would result in a severe disparity between entrants who can afford fresh rubber every race (probably only 2 or 3) and everyone else who is immediately at an unnecessary disadvantage that shouldn't be found in club level racing. While you're list 1A tyres are not ideal, they will be reasonably cheap and therefore unlikely to cause a performance advantage to be found simply by having a bigger wallet. The other added bonus is that the cars are less likely to handle like they are on rails and therefore the skill of the driver is amplified, the braking distances are longer and the racing is much better. Regardless of your overall grip level, what you are looking for is a nicely balanced car, making it predictable and good fun to chuck around. Hope you find the right tyre! |

My first point is that I do not have a lot of cash for my motorsport. My second is that - with the greatest of respect - I find it absolutely impossible to agree with what you have said. I have thought this through over a long period and have discussed the subject with many co competitors and the simple fact is that very few people out there really appreciate what list 1A is all about. If you are really concerned about saving money and preventing people with more money buying better equipment than you, why don't you lobby for kwik fit exhausts, brake pads and shock absorbers. If you think it through the argument for these items is precisely the same as for the kwik fit tyres you favour. And 1A can end up costing you money - as it did with me. The tyres in 1A are included in that list by the tyre manufacturers. It is not the MSA who distinguishes between the tyres that are in 1A or 1B. The MSA don't have any input. So when a tyre company decided that a tyre that had been in 1A for years had to come out I had to buy new tyres. Some championships (but not all) now say that a tyre that has been on list 1A in the last few years is ok but I just don't understand why if I don't run 1B tyes I have to run something that's in 1A. Another example - I thought about competing in a car that has metric wheels - only one tyre fits these wheels but I still thought the car would be fun to compete in even if not massively competitive. No go - the relevant Michelins aren't in list 1A. What has that achieved for anybody?? The cheapest way to make a car faster and safer is to buy the best tyres you can afford. If these are R compound tyres intended for motorsport use, what on earth do you achieve by banning them? I seriously question whether you really save much money. And why pick on tyres?? The tyres you use directly affect safety as well as performance. Why not pick on expensive shock absorbers or why not just say that everyone has to compete in the same car as you with a budget that's no bigger than yours???? I think the answer is that tyres are easy to police and list 1A appeals to people who like to check out what equipment other people are using so they can have a really good moan about it. Sorry - rant over See you at kwik fit, then...... Last edited by jonners; 26 May 2006 at 22:51. |

Nowadays the wheel has turned (groan) and the List 1A tyre of choice is the super-cheap Stunner (though still in 15" which is anathema to a light agile car) whilst in List 1B world you need the pricey and short-lived Avon ACB10 in A24 compound. Plus ca change... Mike |

Jonners,
Wow! I can't remember seeing someone miss a point so angrily! You obviously harbour deep seated opinions (a good thing) about the subject of tyres. But please don't take it out on me! I apologise if I didn't make my point clearer. The view expressed in my post is purely aimed at those series that mandate a very expensive tyre, thereby giving no choice but to pay out big money for items that that are likely to be in the bin in a short space of time. With regards to your bizarre parallel with Kwik fit exhausts and so on, it would be fair to say that with brake pads aside, none of the items you are talking about suffer from the same vital attribute that makes tyres expensive, in that racing miles don't tend to wear them out quickly. They are bought once every few years. Tyres on the otherhand are a different matter entirely. I'm afraid that I don't see how many of your points relate to mine. I am simply expressing the view that if a series wishes to have a control tyre, then make it a cost effective one, not one that instantly renders potential competitors unable to justify the cost and therefore unlikely to compete. You cannot argue that potential competitors choices are unaffected by cost! Therefore, it needs to be considered. I make no points about banning the use of expensive tyres in series that have free regulations. The whole point of those series is to offer a place to race to whoever wants to enter. Therefore, those entering understand that it is unlikely they will be competing with those with a bigger budget. My opinions are aimed to question championships that wish to have a single tyre policy in the interests of perfomance equality. If you're going to do that, then go for a cheaper rather than more expensive tyre. You're entry numbers will certainly be higher and the racing probably better. I also express no opinions about championships that allow 1A but not 1B. That is a different argument from this one. I happen to agree with the points that you make about that stuff, but don't understand how it relates to the view I expressed. You seem to have drawn the conclusion that I am suggesting that all racing tyres should be banned and everybody should run on list 1A? Again, I was merely responding to the thread author's complaint that the mandated tyre choice was not of the performance level he may like to run. My point is that if they're going to mandate a certain type, then its better that its the cheaper end of the market. It is very likely that those who determined the tyre regulations for the series he is looking to compete in are providing what their existing competitors want. If you wish to spend spend spend, then there's no lack of championships that provide the need and clearly this championship is trying not to be one of them. For the record and in response to your explanation about the problems with List 1A and 1B tyres, if the organisers are pitching regulations in a way that results in a limited choice of tyre and maybe no good solution, then of course its wrong! If you've had this experience, then I'm sorry to hear that, but its a different subject. Incidentally, if I CHOOSE to run in a series that has people using better tyres and it is within the regulations then I'm unlikely to 'moan' about it aren't I? Are you confusing me with somebody that has irritated you by doing that? Best Regards. |

I run on list 1a tyre (Toyo Proxes T1-R's). This is a control tyre for the series.
I get a set of tyres for £140 and then spend £50 having them buffed. They last at least half a season. Other people that used to run in our series have gone on to others that allow list 1b or slick tyres have ended up spending £1-2K a year on tyres and not even being competitive any more. They have also ended up with a far less reliable car. Yep, list 1b tyres are amazing (I run Kuhmo's on the kit car) but list 1a allow me to keep racing competitively whilst having a baby/life/house. When I win the lottery, yep I'll be straight on slicks, along with the £2-3K to uprate the car to suit and the extra £3-5K a year to run the car competitively. |

How interesting about the Stunners, I've fitted them on my road car and have to say they seemed good, didn't realise they were a demon tyre for speed events. Tnx for info
FWIW I've first hand knowledge of 1a control tyres. I well remember racing on slicks when you could buy your grid position with new tyres. Saw it happen many times, couldn't afford to do it myself, so always at the back. Now I'm racing on 1a control tyre, tyre performance is constant throughout the life of the tyre which is well in excess of a season, and my races consist of 30 minute runs around proper circuits. It's the same for everyone, no-one buys an advantage, great for us on a budget. >>>>>So when a tyre company decided that a tyre that had been in 1A for years had to come out I had to buy new tyres Like we have to buy new helmets, new belts. Damned petrol keeps getting used too. How often do you have to change 1b tyres? I knocked out 032Rs for a pastime on my Turbo. It happens. We get over it.

Er, my aplogies...
...all my toys are back in the pram now My post does sound like a direct assault on the previous poster - hope no offence was caused I just get enormously frustrated on the subject of tyres in amateur motorsport The one thing I've learnt is that tyre regs never suit everybody - a fact of life. But there is this view that the way to appease everybody and make things fairer is to specify list 1a it doesn't work. my car is very hairy on list 1a and also less competitive than newer cars on 1a. 1b actually evens up the playing field so there you go, an example of tyre regs not suiting me whereas they wouldn't bother someone in a different car. someone might say you just have to compensate by developing a different area of the car - er, but there goes the money I've supposedly saved on 1a tyres. And someone with more money than me will have exploited that area of development already so the notion that the playing field has been levelled by 1a is nonsense. Tyres are consumables - yes, better ones wear out more quickly. so do better engines. why not specify halfords own brand oil and other consumables too?? Helmets?? analogy doesn't work - we don't have to buy new helmets just because the manufacturer withdraws perfectly acceptable items from a list in the blue book that was created to appease the sponsors of a production saloon car series in the 80's (a tyre manufacturer!!) as for kwik fit shock absorbers - rebuildable items designed for motorsport might need servicing more frequently so let's please Karl Marx and ban them and send everyone to the tyre centre paradise as for quick fit exhausts - the point is the same - why not prevent people from spending too much money on exhausts??? just because 'motorsport' tyres wear out more quickly downgrading the spec of the ones you can use is daft. Sorry but it really is. th point about money is nonsense all the ib tyres i've ever bought have needed replacing before they have worn out - and my car is double driven at events and driven there and back on the road. perhaps you guys compete more often than me - clearly that's not fair...you get more practice than me, more development and more fun. We've got to put a stop to that. I'm not ashamed to admit that it took me years of competing to realise how important tyres are and the huge effect they have on performance - i don't have limitless funds (i do have a wife, life and 2 children) but can't see the point of competing on tyres that aren't th best available for the purpose - for every reason to do with car performance don't mess around with tyres... imagine telling the members of a golf club that inferior balls only are allowed because some members don't like losing expnsive ones namby pamby nanny muesli monster loony let's make life fair sticky tyres are emotionally unappealing confound this pinko list 1a commie nonsense!!!! I'll get my coat... |

There seems to be a mind set in the south west of the UK regarding soft so-called road tyres in speed events. The insistance on allowing sticky road tyres there when the rest of the country mandates List1a has long been a nightmare to those who live remotely near the borders of this great divide. List 1b, incidently, has only ever been used in the south east for speed events in the past (and now for road kit cars) - other past regs elsewhere were "any road tyre" etc.
Regardless of the arguments for either, those who have created this ridiculous situation over far too many years should have long ago been taken out and shot. Having had to run both, sometimes at the same venue on different dates, 3 sets of soft rears a season against one set of List1a rears over 3 seasons is a convincing argument to me. I have usually also found the strongest advocates for sticky tyres are those with the strongest engines. Lower grip equals a more level playing field. Obviously the MSA must depend on the manufacturers to assess which tyre goes on which list. What the MSC/A can then do is ensure that once a tyre is correctly on the list, it does NOT get removed - ever, if still used. Some of us remember when the Yokohama rep failed to turn up to a meeting and the others placed a star against all Yokos (indicating removal next year). The scandal of that was that no one at Colnbrook thought it strange or checked it out - competitors had to alert them. Democratically elected MSC and MSC committees would be a first step to eliminating some of these nonsenses. Last edited by Anuauto; 29 May 2006 at 13:35. |

I have run my Camaros on list 1a Falkens and laterly one car on Dunlop Formula R's which are OK for the historic championship and a reasonable wear rate but limited in available sizes and the the other car on Kumho Medium compound. The wear rate on those is on the high side I would say I have done the equivalant of three races on them and I would say they have another two or three races maybe more if I swap them around. I personally prefer to run on the 1b's as I find them a lot more predicadable and less likely to launch me into the barriers at a moments notice than 1a's and just one of those excursions can cost an awful lot of tyres. I also found in the championship I was running on 1a's the guys were buying bigger and bigger rim/tyre combos to compensate for the lack of grip.
I think for the next set due to the weight of my car I will opt for the Kumho hard compounds as suggested by Graham Barr, these are the ones I believe the BMW championship specify and I think would give a reasonable wear rate and would probably last the race before going off as these did a little after 14 hard laps at Brands yesterday. The other advantage is they come in a great range of sizes including a low profile 16" tyre that suits my car fine. PS: Another possible saving to consider is these 1b covers work well in the wet a hell of a lot better than 1a's which I found were virtually uncontrollable on my yanks when it started raining. In fact invairable I may just as well have pulled off. Both these Kumhos and the Dunlop R's I have now tried in the wet and they were not nearly so skitish so there may well be saving there for the clubman racer.

Getting back on topic a bit , as I previously stated, there have been occasions where for speed events at least the cost of list 1A regs have far outstripped those of list 1B. For circuit racing I can see the story might be different. The SW (speed event world) doesn't allow crossplies, which means that the best list 1B tyres are a lot cheaper than what have traditionally been the best list 1A tyres and don't need buffing either. And on a light car will easily last a season. The SE events now allow list 1B too. Mike |

Thats another good point, the Kumhos did not need buffing.

The relevant classes (ie non slicks) in the South West speed championships allow any road legal tyre except crossplies - 1b is not mandatory. So it's up to you, as it should be.
The trouble with 1a - and this is a point everybody misses - is that it creates problems as mentioned above. If list 1b and crossplies are not in favour, why not allow any road legal tyre except 1b and crossplies??? Point taken about golf balls - but tyres are so fundamental to motorsport - just seems ludicrous as for more powerful cars favouring 1b you could also make the point that the lesspowerful ones favour 1a looks like i'm in a minority on this one |

Actually heavier cars may have a slight edge with List 1a stuff as they will generate heat quicker I would have thought but then again maybe not as they will eventually get too hot. I must say these Kumhos seemed to last the race better than the 1a Falkens though. I had to either set the pressures for very lairy for the first couple of laps and last the race or go well from the off and get very unsettled towards the end. I suppose I should have tried filling them with nitrogen or something as the pressures came up about 15psi :-(

As already stated, the SE speed grouping has not gone list 1b (again - it was there in 1993 or 4), only kit cars can now use 1b. Real cars still have list 1a there, as they do in midlands etc.
The tradition of production cars in speed events, going back many years, was to bring racing tyres (before slicks arrived) in the car, even if driving there on the road, and change to them. Slicks last longer than sticky road tyres and would be cheaper overall. On hill climbs they are closer to performance of sticky road tyres than sticky road tyres are to list1a (personally involved in back to back tests that confirmed manufacturers' advice). Another bit of more recent history worth remembering is that these ludicrous "soft" road tyres were unheard of until the routine use of Michelin TB15s (a medium compound Intermediate rally "race" tyre) in road rallies was jumped on. Suddenly, instead of running a whole Motoring News Championship road rally on a set of TB15s, top runners were carrying 4 spare Avon CR28 Sports etc and changing the rears twice. What a nonsense. What has comparatively recently appeared on list1b? - Michelin TB15s! If kit (sorry "limited production") cars are now sold with sticky road tyres, that is no reason to allow them to be used. Perhaps the manufacturers of such cars should be told to show more social responsibility and not fit them to cars sold for the public road. Sticky road tyres are the cause of unlimited misery and regulation confusion in club motorsport over far too long a period and should have been put down at birth. |

Why do the real cars have to have 1a?
why not any road legal tyre except 1b and crossplies? i don't see the relevance (any more) of the traditions in speed events - the tyre world has moved on and R compound tyres are very well established - as you mentioned they are even fitted by some manufacturers - including BMW I agree that Michelin TB's should not be on list 1b but as I said the MSA takes no interest in the lists so why are they used?? As an occasional competitor in ASWMC speed events I have come across people from other regions who bemoan the use of 1b tyres and also the class split at 1800cc. Both of those are what the competitors in the championship want so that's why the regs stay as they are. Why do all the regs have to be the same nationwide? As stated above the ASWMC regs are sensibly drafted so you can run with 1a tyres if you want to. The point i've been trying to make is that restrictive regulations cause problems if they're not thought out properly. The regulations cause problems not the tyres. We can't make the tyres go away - they're here to stay, so why not legislate for them sensibly?? Seems to me that the 1a brigade isn't devoid of those searching for the last nth degree of tyre performance, changing tyres as soon as a new 'must have' appears, shaving tread off etc... I repeat I'm not a rich competitor - i haven't even got a trailer but even I get annoyed when people complain about competitors with well prepared cars who want to change tyres. why not moan about people who set up their suspensions properly or buy lightweight seats etc etc in amateur motorsport it's ludicrous to make inferior tyres mandatory. |

I think the fact that the arguments for 1b aren't predicated on a "thou shalt not..." sort of attitude says it all.

Where exactly on this thread have the 'list 1a brigade' said "thou shalt not"
As opposed to your constant "thou shalt not"? |
