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 Hummer platform, you may come across flotation sizing designations. These will typically read as 35×12.50×17.
Rotate Hummer EV tires every 7,500 miles per manufacturer specifications. Due to the vehicle's heavy weight, proper rotation is crucial for even wear. Learn more about proper off-road tire rotation.
For enhanced performance beyond factory options, consider rugged terrain (R/T) tires which offer excellent versatility. The Repulsor R/T provides superior traction in rain, sleet, mud, and snow while maintaining comfortable road manners.
There is no one answer to this question. Every truck and every tire require a different tire pressure. The best way to find what tire pressure is required is to check the driver's side door for a label that displays the recommended tire pressure for that vehicle. It's important to note that this recommendation changes depending on the load of passengers, as well a cargo load. Learn more about light truck load ratings.
Due to the Hummer's heavy weight (approximately 9,000 lbs), tire life expectancy can be around 20,000 miles with regular rotation. Actual lifespan varies based on driving conditions and maintenance.
As stated above, the way you plan on driving your Silverado will help you make a better decision on what tires to choose. If off-roading and driving on unpaved roads is a normal occurrence, then dedicated off-road tires may be beneficial.
