2004 2.5T... Have 17" wheels right now, but looking at possibly purchasing some 18" wheels. Since it's a bigger wheel will it rub? Affect my speedometer? Where is the best place to get wheels online? Thanks for the help!

 

You will more then likely rub at full lock in either direction.

Probably will throw the speedo off slightly.

 

My S60-R has the stock 18's and they rub on sharp turns. I've read you can remedy it by purchacing wheel spacers.

 

Keep the overall diameter of the tire the same, and you shouldn't have any issues. THis is supposed to be a great site...

Find the "tire tech" section. Thatwill answer your questions too.

 

Thanks, that tirerack.com is an excellent site, the one I've actually been looking at the most. Thanks!
