I will list tire sizes that are similar to OEM diameter, as this should help tire shoppers. The heights shown below are approximate, based on calculations. Refer to tire manufacturer's specs for the most accurate tire diameters. We recommend you stay within 0.5" (plus or minus) of the factory tire height in order to maintain accurate vehicle systems. This gives you an acceptable range of 28.2-29.3" diameters. Wheel widths shown are recommended, and only serve as a suggestion for proper fitment/appearance/performance.
