They did,and it worked.But not for Bridgestone and Ferrari.

Can they use the Soft more than once?

Any chance of a 3-stopper Sprint on the Soft's?

It's quite difficult to produce a tyre that is both durable and providing a lot of grip. Bridgestone lacks the incentive to produce such a tyre.

I think the 2 stop strategy has been killed by this supersoft tyre, 3 stops will be petty much par for the course - two long stints on the prime and one short blast on the soft - it appears the end of the race not the start.....
unless, you do a two stop with an insanely heavily fueled long first stop and the rest on the supersoft? Brundle was saying though that the KERS reduces fuel tank space - so that would be the option for KERS-less cars only....more things to think about for race engineers.

or cars which dont sacrifice tank space for kers

Yes, as long as they use both compounds at least once.

Do you count the start as a stop? A two stop strategy already offers you three stints.

There is a lamp posts and gaps between issue there. I think parkingjedi is talking about nestop/two stints as thos was earlier in the thread.

parkingjedi · 30 Mar 2009, 13:24 (Ref:2428992)

oops yep got my words all cocked up - I mean one stop two stints as AA highlighted.

I think that strategy (1 stop/ 2 stints) is gone this season.
The 2 stops/3 stints will be the one they all use.

It really depends what tyres Bridgestone bring to each round in my view. Dont forget that the "soft" option tyre wont always be this super-soft compound, it will just always be two grades softer than the "hard" compound. If they actually did bring a hard compound tyre, then the "soft" option would in fact be a medium grade compound.

Calling the tyres "soft" and "hard" is confusing in my view, since they change from race to race. The ones with the stripe are the "Softer" tyres and the ones without are the "harder" ones. What compound they actually are will range from super-soft, as this weekend, to "super-hard" or whatever the tyre at the other end of the scale is called.

It isn't inconceivable in my view that the softer tyre will be the main option at some tracks, possibly Monaco, where the relatively low speeds won't degrade the tyre as quickly and grip is at a premium.

Just a thought.

The main cause of tyre degradation is heat generation created by cornering stress, not speed. Monaco and similar 'slow' circuits put a lot of stress into the sidewall by constant changes of direction and constant acceleration and braking. The soft tyres will not be that great at Monaco, fast in practice over one or two laps but not much good as a race tyre.

This is exactly it. It will take hardly any time for a consensus to emerge: the teams just have to get used to the degree of difference between the two compounds, which is, as I understand things, going to remain broadly stable from round to round.

Bridgestone should bring three or four compounds, and the teams should be allowed to use any compound at any point. Have no rules about what compounds have to be used or how often.

I think we can safely say that an absolute crapload of tyre-related money has been saved from the in-season testing ban, so I am sure we could have compound variation like this now.

johnh875 · 1 Apr 2009, 01:53 (Ref:2430217)

I think there are actually 4-5 compounds, and the ones used will depend on the track and typical weather. The change is that this year they brought compounds 2 and 4 (say) to Melbourne instead of compounds 3 and 4. I think it is a good idea, if they are bothering to have different compounds they should have an effect. Last year there often wasn't a great of difference on the option tyre.

Dutton · 1 Apr 2009, 03:46 (Ref:2430259)

Yes, but bring them all to each race without restrictions is what I meant.

Marbot · 1 Apr 2009, 16:36 (Ref:2430698)

Ferrari's KERS is causing problems with tyre wear.

http://f1.gpupdate.net/en/news/2009/...ferrari-tyres/

Which begs the question: If KERS were to be made more powerful,how long would the tyres last then?

Dutton · 1 Apr 2009, 22:05 (Ref:2430923)

The team can always just not utilise the KERS boost so much in the shorter term. In the longer term they will improve their understanding, thus at least improve the situation (maybe even eradictate the problem entirely).

This is exactly why significant rule changes are often so interesting,

.

Bridgestone will learn lessons through this year, too: in the event of increasing KERS loads, presumably Bridgestone will work with the teams to identify tyre improvements for coming seasons.

I like this idea...

Okay then, well sort it Ferrari...
