RE: [T3] How do you go so fast?


The full tire spec is needed as 195x15 doesn't give the wall height.  For
you it is probably true if the wall dimension is greater than 65, like 70 or
80, but definitely not possible if 60 or lower.

I've been running 195/60x15 rubbers for many years and through speedo check
sections and various people driving next to me (which isn't too accurate a
method) and by simple calculation (see my Gearing Analyzer or Jake Kooser's
AutoMath workbook) this tire combination WILL throw off the speedometer
reading and more so the faster the car travels.
