I noticed that once over 35 hot these tires slide around more. I had great success auto crossing these tires at 30-32 hot...FYI They were great tires...best street tire I ever ran on a Porsche

Related subject, my TPMS read 31/36 on the dash, but when I check with my tire gauges (used multiple) I am at 33.5/38. Is there a calibration procedure for the TPMS digital read out, or is it compensating for temperature?

Just about to buy a set for track use... can anyone comment on how they are holding up? how many track days are you getting with them? I see they are 100 Treadwear, I want to get a tire that will last a season (~8 track days) are these a good bet?

Cup 2s would also be a good choice.

They are great dual purpose street and track tires. Similar to my old favorite no longer available R11s. AD08S have gotten so expensive since the day they were introduced so I kind looking some alternatives. Great tires. Keep 35-36 hot on a track. For street it is your personal choice like everyone said. No need to crank to 40 rears for sure. May be 33-38.

Not all air pressure gauges are created equal and not all TPMS sensors are accurate. I have a friend who swears that most gauges are off 1-2 lbs. and whose air gauge costs in excess of $750. You can get your gauge calibrated so you know how correct or not it is reading.
