getting bigger rims = odometer/speedometer changes?

[songa]

thanks for the input. well i really dont know much about cars, esp. stuff like how wheels affect fuel economy, etc. so i was just tyring to find out more information about them. 0.1% difference is minimal but over a long distance, the odo will be reading a value much less than what you actually traveleed, right?

in any case, i probably will end up getting 15"

thanks guys
