Hello, Did my first trackday this week and tomorrow I'm going to the ring for a day. I've searched but couldn't find any info on pressures for 19inch tires, manuel mentions circuit tire pressure for 18inch only. The door sticker says 2.4bar front and 2.1 rear. I set them at 2.3 front and 2.05 rear cold. After a few laps + cool down lap I measured 2.7bar in the front and 2.3bar in the rears. I think 2.7 is too high warm? The tire side wall mention something of 40psi max = 2.75bar but is this cold or hot? Since I'm obviously no expert I'm asking some help/advice here, anyone uses the 19inch wheels for some trackdays? The front tires are Yokohama advan sport v105 and the rears are still the original bridgestone potenzas Greets from Belgium
