GMC Tires & all possible tire sizes

It has never been easier to choose your GMC tire size. Below you will find a unique directory of tire sizes across GMC models. Get the best tire size for GMC by specifying your GMC model and year. Our catalog provides data with possible tire size range for GMC models.

Each car goes with a specific tire size that has three basic parameters – protector width, aspect ratio (distance from the ground to the lower edge of the rim) and rim diameter. Tire size measurements are not of a random choice. Those dimensions emerge with many factors and calculations taken into consideration by the manufacturer as they can have a huge impact on such car performance indicators as speed, gas mileage, driving comfort on a highway or off road, safety, etc. We recommend installing the original tire size for your GMC provided by the manufacturer.
