i only did this for the very first run, as these tires have not seen the track in about 1.5 years.
they are Goodyears, but I dont remember the exact size (they are big)
this run I had 9psi (went with what my brother runs, but he has smaller tires too), the next run I went to 8.5psi...this is when the car seems loose all the way down the track (with 8.5psi)...unless it was just more windy on the 2nd run...I really didnt notice the wind before or after either run.
this is all new to me, this is the fastest car I have ever driven/owned.
