Ferrari Mailing List: Re: some F355 questions

[Grahame Reinthal (grahame]

Apart from Ferraris in general having over-optimistic speedos, the speed
issue is, of course, also affected if you have changed your wheels' rolling
diameters in any way. It may be that the current tyre of choice that you
guys are fitting on the 355s is also slightly smaller in circumference. You
can easily work out the difference by calculating the circumference
difference between the original standard-issue tyre and the current tyre or
modified wheel and tyre you may have fitted (using c = 2Πr).

 

Cheers,

Grahame
