Default Current thoughts and experience on Track day/Autox Tires

Actually the set of Toyos I acquired for a great price were 205/45-16 which dropped my car another 3/4" but most importantly dropped my top speed by prolly 10-mph minimum. The diameter does change with that size.

Doesn't matter so much for AutoX, but for the longer straights on the track events, I was loosing seconds. Example: on the freeway, my speedo would read 70mph. GPS would show 62 mph.

ThunderHill has longer straight runs. I'll see if it makes a difference in my times. I just hope it's not a bizzilion degrees next weekend. Meaning 100+ degrees. [emoji15]
