What size tire?

[Chris Kulbaba]

I purchased some rims, they are 20" 9" wide... what size tires do I need to keep the speedo accurate?

Depends on what size wheel/tire you are at now. Plug your numbers into this tire size calculator:



Speedometer difference is listed below the graphic.

Wow, that works great



275/45/20 is what I should be looking at, but what about the width for a 9" rim? or does that matter?

That doesn't matter. 275/45 is the closest your gonna get to stock with the rim sizes.
