There's been a lot of questions on what size tires and wheels we can use and try not to throw off the traction control or speedometer. I threw a chart together with all the sizes I could think of (I'm sure I missed a few). I didn't include any sizes that would be more than a 5% difference than the factory specs. I sorted them by circumference so find your current size and see what the closest match would be in the wheel or tire you're looking at. Diameter & circumference are in inches. Generally speaking a 1" difference in circumference is going to change your speedo a little more than 1% (80 mph on your speedometer is really approx 80.8 mph if you go bigger or 79.2 mph if you go smaller).

If you don't see a size let me know. If you find this of use ask the mods to put it in the FAQ section.

This one's sorted by size instead of circumference. I didn't realize how hard it was to find a tire with the other chart.

If you don't see a size let me know. If you find this of use ask the mods to put it in the FAQ section.
