Default Re: Max pressure printed on the side of the tire you run

is what I've always been tought. Put a chalk line on the edge of your tread and over onto the sidewall. Run a few laps and come back in and check where the chalk is off. If you are not using all your tread block, take a little air out, if you are using all the tread and rolling over onto the sidewall, add a little.

Default I've found that cold 32F/34R heats up to around 40-42 depending on the track....

and that seems to be a good place. I've only run this tire size once, though, and so I'll probably be experimenting some more.

Default 38 hot is good place to be for most tires on the track with these cars. do 40 in the rear

if you need help reducing understeer.
