I have no issues getting them up to and over temp on occasions at the track. I have a starting psi of around 28 with a target of 35-36 when warmed up.
I am using Apex ARC-8s with that tire and I drove 5 hours to Road Atlanta on them and it was not as enjoyable as a more street oriented tire would be. I was wondering if maybe the NVH issues came from the tires or the wheels.
