Stock tire is approximately an 80 aspect ratio, but 79 might be more
accurate. Aspect ratios are never dead on accurate. I use 205/65 on
my TR6, and calculated speedo error to be only 2% or something like
that. Since there a much higher selection of "aggressive" tires in the
65 ratio rather than 70, I decided to go with 65. Plus, the shorter
sidewall of the 65 helps handling even more.
