I am about to buy my friends 17 by 7.5 inch Neeper concept rims and would like to know what that would do to my car as far as speedometer reading and weighing the car down i currently have the stock 14's on.
Thanks for the help

with a larger diameter rim, u should use a tire that has thinner walls to offset the gain in rim size. by doin this, the total circumference of the wheel will not change.

u have options on what thickness of the wheel well u can get.

hope that helpd

Just like Vegas heres your sizes and speedo readings:

215/45/17 - You will be 0.5% too fast, so when your speedo reads 60mph your actually going 59.7mph

225/45/17 - You will be 0.9% too slow, so when your speedo reads 60mph your actually going 60.5mph

These are the best sizes according to the tire calculator. Anything else just throws your speedo off too much.
