Hi Guys,

I need some opinions please. I have a 2001 E46 M3 that I use mostly for track days.
Im running an AC Schnitzer strut brace in front and running Bridgestone RE-11s semi slick tires on 8j 9j 18" rims. front 235/40 rear 265/35
What advice do you have for tire pressures?

Thanks in advance.

 

It shouldn't be any different than stock tire pressure.

 

when you run on the track you put much more heat into the tires, which means the air expands an pushes up the tire pressure. The has a massive impact on the handling. After two laps running standard pressures 2.2bar front and 2.4bar rear the pressure shot up to over 3 bar and the car was understeering massively. If possible can someone comment that has experience playing around with different pressures? Thanks a mil.
