with bigger wheels on ur dynamique, is the speedo f**ked?

with 17s & 205/40x17 tyres the rolling radius is about the same as the standard 15 in. wheels, so the speedo reads about the same.

Well on mine its a bit out. Although mine had 14s as standard. The rolling radius is a few per cent bigger, and it does show. Speedo appears to be roughly 10% too slow, so I have to slow down to 45mph for cameras in 50 zones, 27mph in 30 zones, etc.!

Yep like Black Fox said the rolling radius is about the same , only bout 6mm difference, so the speedo isnt really effected
