GMC Sierra 1500 Steering Wheel Sizes by Year

The GMC Sierra 1500 steering wheel size listed for the catalog years is 15.0 inches in diameter. This stored measurement applies to the model-year range covered here, so use it as a reference when comparing steering wheel covers or checking fit.

The catalog includes years 1999-2021, and the available Facts do not give separate diameters by year, engine, or trim. That means the listed figure should not be read as proof that every individual truck has the same original wheel. If you need a confirmed measurement for a particular vehicle, check the door jamb or the owner's manual.
