will probably run 40 or maybe 42 cold with these tires my next autocross.
I don't have time to argue all the points you've made in this thread so far, so I'll just point out two things:
  1. As the "OP", I'll have to point out that the tire damage is not fro running too little pressure. If anything, these tires got too hot from too much pressure at times since it's hard to control their temp on track, especially compared to RS-3s or Star Specs.
  2. As an autocross instructor with our local BMW CCA chapter, I hope that non of my students show up with 40-42 PSI of pressure in their 3500lbs+ cars... Unless it's drift day! Which it never is
