True wheel size

If you buy a slightly larger wheel then you get to cheat your odometer, for every mile you drive it will only read .95 of a mile. or some figure like that.. If you buy a smaller wheel then you will be adding miles that you did not drive onto your odometer!!!!!

Here is a great link to calculate all your wheel size questions..

215/35/r18 don't even come close to rubbing on my 02 civic.. I'm getting 225/40/18's next time around !!

And increase your rotational mass, and change the accuracy of your speedometer.

I certainly would never buy one thing over another just on account of its effects on my odometer. Let's just say that the change is .95, and you put 100k miles on your car. It'll read 95k miles on the car....which is negligible when compared to 100k, thus it will have little or no effect on the value of the vehicle. If you put 50k on the car, then it'll read 47.5k, which is still pretty negligible and won't really affect the value. See a common theme here?

But, based upon the calculation that I just did, you'd be changing it by a factor of roughly +/-.005 from stock whether you go with 215/40/18 or 225/40/18, respectively. Based upon that order of magnitude, for every 1000 miles you drive, you'd be changing the odometer by 5 miles.....that's 500 miles for 100k.
