Dunlop Historic Racing Tyre Pressures
Running Lotus Cortina in HTC class with HSCC and trying to get to the bottom of tyre pressures. Have been running at 28psi Cold coming up to 32psi Hot BUT think this might be way too low. Pictures of car show tyre wall deflection that might suggest pressure too low. Found this article that talks of range of pressures between 32 and 43/44 psi. Spoke to another competitor who suggested they need be to be near 40psi hot. HTP Tyres appear vague in their guidance, as do Dunlop themselves.
Picture of me struggling to get anywhere near apex at Hairpin at Cadwell Park - Look at tyre.
Document attached too.
