Tire Size Calculator

This tool is provided to assist you in evaluating alternative tire sizes for your vehicle. Simply insert the stock tire size recommended by the vehicle manufacturer in the left column and the alternate size you are considering into the right column. Click "Compute" to see the overall tire diameters and the percent difference between the two.

Note - To avoid potential problems with ABS and traction control (ASR, ESP) you should always maintain overall tire diameter within plus or minus 3% of stock. This tool only addresses the issue of tire height. IT DOES NOT address the issue of tire width or any interference with the inner fender.
