what size am i looking for
 

what wheels will fit the stock tires. I want to buy some wheels from wheelsdirectonline.com and have sizes such as 18x8 18x9 ect. And what is the bolt pattern, or in other words, which ones will it be compatible with, thanks

18x7, 18x7.5, or 18x8 size wheels will fit stock tires

Bolt pattern is 5 x 114.3

However, you have to consider the right offset, so the wheels do not stick out too much

Do a search in the forum, plenty of info.

great, but which one would be the best fit, in other words, which one would you go with, thanks alot for the info.

Look on www.tirerack.com at the tyre specs for the size and model of tyre you're interested in and look at the "Rim Width Range" column. This is the size of rims that that tyre will fit.

Here's a direct link for Tire Specs for Bridgestone Potenza RE040
