Just wondering is there any way to calibrate the speedo to ensure its still reading properly? My car is running on 18" mv2 style with 225/40 tyres on them but going by the original spare the standard wheels i think are 15" 205/60.
I worked out that the speedo would be reading about 13% slower than actual speed going by wheel circumference, is there any way to count this in the speedo? Or is it just a case of bearing in mind your going faster than is being let on to you? This has already affected me i was cruising along quite the thing not really thinking bout this and the thing and got pulled by an unmarked cop car:frown So will already always be bearing it in mind was just wondering can you correct it?
One other thing on the side, how do you tell if an alloy is genuine bmw or not?
Cheers guys
