Need to Find what size wheels will fit my car

I have searched around for a source for this question and came up with this site called SizeItUp.com. The site does require you to register an email address but information you can access if amazing. Select your vehicle up to 2009 models included and you are given the exact tire size that came on the vehicle plus any optional size. Then chose the Size you think you would like to install, like some 22" rims for example. The site will give you a list of all tire sizes and dimensions that accompany the 22" rims. They take all the guess work out of the equation. SizeItUp.com is truly a great tool to add to the Tool Box!
