The original equipment size was 225/75-16. The optional tire size is 245/70-16. The use of any other size will alter your speedometer and adversely effect mpg and handling. Stick with one of these sizes.

Generally no for vehicles that were not designed to use differing tire sizes. For vehicles designed to use equal sizes, using different sizes can lead to unsafe handling quirks.

Look inside the driver side door jam is should tell you tire sizes. If you cannot find it, refer to your owners manual.
