Bigger rims and speedo

[Timmos]

Curious as to what happens with your speedo when you increase the size of rims on your car.

Obviously it's gonna knock it out of wack. Can this be fixed? easily?

Thanks

If you go bigger rims, you then need to go smaller profile tyres, to compensate.

If you have the same rolling diameter, they should be close / same.

If not you can get them calibrated easily enough.
