Can anyone tell me, does the overall rolling wheel circumference of a car's wheel (tyre) still have a direct correlation to the accuracy of a car's odometer? I know it used to in the 'old days', but I have no idea how the odo and speedo pick up their readings now.
It looks like I need to change the profile of my rear tyres on the Trofeo due to a lack of availability of the size they are currently wearing and I am curious to know if these readings will still be correct. It's not hugely important as it won't be doing a great many miles and I would probably use the speedo from a GPS rather than the car's own one but it would be good to know.
It looks like the rears are going to have to go down from a 35 profile to a 30 - as if I needed the ride to get even more firm ...
