Hi
I use to have 205 45 16 wheel. with this wheel size my speedo was about 16% out, ie when i was doing an indicated 100mph I was doing 84mph
I have change the wheel to 205 50 46.
do some one know how to find out if my speedo will over or under read, whit out driving the car?
There are quite a few speed camera near Chesham, I rather not find out the expensive way.
Thank for your help
