Oh, is it? didn't know it affects the speedometer...so it means u may travel at 180km/h
but actually just 179km/h...wow if bigger diameter = not accurate speed reading...
Bigger or smaller will affect, that is why, rule of thumb is to keep it within 3%. But the 3% rule more when going bigger because the bigger the diameter the centrifugal force of a bigger rolling tyre is harder to stop then a smaller one, therefore brake modification may be needed...
