I did a Auto X this weekend and it was a blast.
Tire held up very well at respectably low pressure (compare to MPSS).
I ran 36~37 in front and 30~32 rear, hot.
Tire wear did not even touch the wear marker triangle. I was impressed.
(I had to run 43~48 psi in front with MPSS to keep the letter readable on the sidewall. lol)
I did not improve that much in terms of my time/score compare to other regular drivers but I think I was little too scared to push way further than I used to with MPSS.
After I checked my videos, I don't hear much tire squeal. I should've pushed more. way more.
Next time, I will lower the pressure to 32~34 in front and 28~30 in rear and push much harder. will see.
Overall, I can see why this is THE tire for Auto X.
