Hello ChrisFulton,

I just did a track day and my instructor recommends me to drop the PSI to 32 and let it heat up.

While on track after a few runs my PSS 245/35/18 got up to mid 40s and then eventually the car went into limp mode because the tire I guess got too hot and went from green to yellow.

Front what I learned doing two days of track, let the pressure down and as you track the car it'll warm up thus increasing tire pressure. I believe if I went in at 38 I would be getting close to the limit of PSI for the tire after a few laps.

I hope this helps!
