just one ting!
if i were to change my standard 15""s to say 17"" verada weels
wouldent that change the way the speedo reads?? wouldent it be off a little?? and also would that change the fuewl consumption much??

please help out.. im trying to convince my dad to get new ones so i can have his old ones :D

As long as the overall diameter of the tyre and rim is the same as the old one there shouldn't be a problem.

no it won't change the readings if you keep the rolling diameter the same.
