Below is my rear tire.. look at the Heat mark

The tread pattern of the tire you pictured is the 220 treadwear Goodyear Supercar 3, not the 100 treadwear Goodyear Supercar 3R. 3Rs do take a lot longer than Supercar 3s to warm up on track. If the pressures you mentioned are for autocross runs, they are not directly applicable to a 20+ minute track session because you would have to start with a much lower initial pressure in order to reach the same hot pressure at the end of a sustained track lapping session.

Having run both 3S and 3R quite a bit, just my quick observations.

- 3S warms up quicker
- 3S gets greasy much faster, but holds pretty steady once it does go off.
- 3S pressure range was 32-33h
- 3S lasts 1.5 times, longer than the 3R
- 3S works better with softer suspension (MagRide)
- 3R takes 2 laps to be able to start putting strong lateral g in
- 3R pressure range was 31-32H
- 3R have much less drop off when hot

You’re right I apologize. I thought the whole time we were referring to the 3s for some reason, hence the confusion with the previous post on the up to temp times.
