Vehicle tire size guide
Documented factory tire sizes by trim and configuration.
Each row is one documented factory configuration. Trim, package, and fitment stay in this table. Optional factory fitment is listed with the same structure and is not counted in the headline configuration total.
Standard is the base factory application for that trim. Factory package is a documented equipment-group or wheel-package size. Optional factory fitment is recorded separately and is not counted in the 15 headline configurations.

Optional factory fitmentThe documented factory configurations span 17- to 20-inch wheels and 4 tire widths. Overall diameter varies by 3.86 inches across the primary sizes.
Nominal overall diameter, sidewall, and wheel for each documented factory size.
See the configuration table above for trim and package details.
Compare the nominal geometry of the documented factory tire sizes.

Compare full dimensions โNo. Trim and factory package determine which documented size was equipped. See the configuration table for the mapping.
Factory packages use more than one rim diameter. Wheel diameter is part of the documented tire size for that configuration, not a ranking of trims.
A size that appears on this model is a documented original-equipment application for a specific configuration. It does not confirm that the size can be fitted to every trim without checking wheels, load requirements, and clearance.
Use the factory-size comparison on this page, or the Tire Size Comparison Calculator, to see diameter, sidewall, width, and related geometry differences.
Factory configurations on this page come from TireReferenceโs verified OEM fitment dataset. Equipment can vary by trim, package, market and production configuration. Data & Calculation Standards โ
