pete757 Posted November 7, 2018 Report Share Posted November 7, 2018 Interesting... so what are the normal recommended road tyre pressures for a 430 then? I only ask because that is a lot lower than the recommended tyre pressures for my S1 SR with Pirelli Corsa's... Quote Link to comment Share on other sites More sharing options...
Hakim0v Posted November 8, 2018 Author Report Share Posted November 8, 2018 I have set them in summer for Road use, 30F/33R (cold) but in winter they r dropping lower. Should I increase them? Quote Link to comment Share on other sites More sharing options...
TheKevlarKid Posted November 8, 2018 Report Share Posted November 8, 2018 Cup2's?? I was recommended by lotus test driver (for track use) to set them at 2bar cold. Do a few laps to get heat in them (pressure will rise), then come in and balance them all down to 2bar again hot. At the end of the day they'll be around 1.6bar cold, you'll need to pump them up again for the journey home. Key thing is to start at 2bar cold. 1 Quote Link to comment Share on other sites More sharing options...
Cypriot Posted November 11, 2018 Report Share Posted November 11, 2018 When people tell the tyre pressures for track driving, they are referring to hot pressures, not the usual cold pressures. In other words, you want the pressures mentioned above to be the pressures that your tyres hit when they are warm on track. That means you typically have to release pressure before tracking with the cup 2s. Don’t forget to inflated them again for the drive home.
