Ive got two sets of P1s in my garage. 295/25/19 for when my 305/30/19 RE71RS wear out in 3 months, and 315/30/18 for when my new wheels arrive…

I’ve got a good amount of experience watching the P1s as Sammy Valafar developed them at our PCA LA events in SoCal over the last few years. I can vouch for them being faster than anything else out there at the moment aside from a Hoosier A7, but they‘re close. They like heat and take a run to warm up in 60-70F weather. If it’s in the 50s F or below, they take a couple of runs to warm and grip up. Once they’re warm, I’ve never seen them overheat, they just stay consistently fast. Plus, they’ve been lasting longer than the RE71RS, and the Yokes. About the same as the Nankang CRSv2. They’re fast on everything, NA, ND2 Miatas, Porsches (couple GT3 and GT4 running them), C5, C6, C7 Corvettes. I haven’t run them on my car yet, but soon.
