The two things that affect tires are time and mileage. Naturally, the compounds on tires have a limited lifespan as they begin to breakdown over time. The mileage on a tire is only a general indication of it’s wear and usage. Neither time nor mileage are accurate indicators of a tire’s usability. The reason for that is because factors such as tire storage and care can improve or diminish lifespan. Typically most tires are manufactured to last at least five years under normal circumstances. If your tires are older than 5 years, it may be a good idea to consider replacements.
Reading the sidewall and understand tire sizing options can seem difficult at first. Once you learn the basics of what these numbers and markings mean, it becomes much simpler. Oftentimes original equipment tires use standard sizing designations, such as 255/70R17. However, when upgrading tires, especially for the GMC Canyon, you may come across flotation sizing designations. These will typically read as 35×12.50R17.
Stock Yukon tire sizes vary by generation and trim, ranging from LT245/75R16 on early GMT800 models to 275/50R22 on newer Denali and AT4 trims. Check your driver's side door jamb sticker or the charts above to confirm the exact OEM size for your model year.
Most Yukons can accommodate a modest size increase, roughly 1 to 2 inches in diameter, without a lift, especially with wheel spacers or a leveling kit. Larger upgrades, like 33 inch or bigger flotation tires, typically require a suspension lift to avoid rubbing. RBP's Repulsor M/T and Repulsor X/T RX lines cover a wide range of these upsized fitments.
Standard sizing (for example, 275/55R20) describes width, aspect ratio, and wheel diameter. Flotation sizing (for example, 31.91 x 10.83 x 20) lists the tire's overall diameter and width in inches, making it easier to compare overall tire height across different width and aspect ratio combinations.
All-terrain tires suit Yukon owners who split time between highway driving and light off-road use, offering a quieter ride with decent traction. Mud-terrain tires are better for serious off-roading, but they come with more road noise and reduced fuel economy for daily driving. RBP breaks down both categories on its tires by vehicle page.
Yes, oversized tires can affect your Yukon's speedometer accuracy, gearing, and effective towing capacity if not properly compensated for with a re-gear or recalibration. For guidance on the right size for towing setups, reach out through RBP's contact page.
As of now, Rolling Big Power's site does not list a standalone Yukon vehicle page, only Canyon, Sierra 1500, and Sierra 2500HD are listed under GMC on their tires by vehicle directory. If you're publishing this content, it's worth requesting RBP add a Yukon page so future copy can link directly to it.
