Odometer Reading

DaMonk · 2009-04-21 22:20:34

Just thought of something, if bigger wheels are put on a car, say to from 15's to 18's, is this going to effect the odometer reading on the car by showing less mileage as it was originally configured for the 15 inch tyres? Know it can effect the speedo but is this the same for the odometer?

Yes, if the overall diameter of the tyre is different.

it will depend on how big the standard tyres for the car are. 15 to 18 is a big jump, but as long as the outside diameter is close, then it won't have a noticible effect on your speedo reading. my old car on 18's (standard size 16) actually gave a spot-on speedo reading when compared to the saatnav speed, standard clocks over-state your speed, so as long as the wheels aren't ridiculously bigger, you should be ok.
