18 inch tire pressure for trackday?

Wasn't able to find any info regarding this, so I thought I start a thread on it..

Please share what size rim, tire and cold/hot pressure you run at track. Cheers

18x9 +50 Rims
Bridgestone RE-71R 245/40R18
Cold 36psi front / 33psi rear

Seems to be wearing quite evenly so far without rolling over on stock suspension setup, perhaps I can drop 1-2psi more on a hot day!

I've found most track tires like a 38-psi hot pressure.. Get over 40 and the tires will tend to get greasy. Too low and you will have sidewall rollover in hard cornering. I would start 2lbs over stock and bleed out if needed. Lots of variables here too - tire brand/model, camber/alignment, driving style, track layout etc.

exactly start with being over.. also take chalk and chalk your tires from the side wall to the top of tire.. run laps.. get the tires hot... come out check.. bleed out if need .. check your chalk...is it gone off the side.. then you rolling over your side wall ... so add more air...

if you need to bleed out.. bleed some out.. chalk your tires again run your laps.. when you come off check the check... again... if ur chalk is still there your ok.. if its gone your rollin over

Thanks for the advices guys!!!
