Regarding MPSS, don’t discount it…it’s a fast tire! Actually not much slower than the Hankook, if at all, at the right temperature. The main difference is the window of time for optimum grip at the track which is much shorter. Like 3-4 hard laps on MPSS as opposed to 10-12 consecutive hard laps with the R-S3 or R-S4 at a sub-2min track. The MPSS can’t handle the heat and wear out very quickly, but if you can get into rhythm quickly and produce a nice flying hot lap before that happens, the grip is very close to the Hankooks.
With that said, I’m sure Randy’s skill and experience more than makes up for any difference in performance that these two tires may have!
Comparing tire/wheel sizes:
The MPSS on the 1M were 245 / 265 on 9.0” / 10.0” wide wheels (diameter 19”).
The R-S4 on the 135i were 235 / 255 on 8.5” / 9.5” wide wheels (diameter 18”).
