Please can anyone advise on the best PSI for a P1 with 18s 225/35/18 for a track day
I normally run 34 Rear and 32 front

I was thinking 41 rear 39 front.

Thanks

Rick

Ric, that's about right. If its wet, leave them as standard, if its dry add 5-6psi to your normal settings.

If you go too high, you will have reduced grip and will rapidly wear out the centre of the tyre's tread. Too low and the edge of the tread will suffer.

225's on 18's wear much better than 16" or 17" tyres on track.

Thanks Pete
