Ok we’ve had our vegetables; let’s get onto the meat and potatoes. Tires come in so many different shapes and sizes and not any two are the same. They have set designations, and this is what sets them apart. There are a couple of popular designations for the GMC Sierra. We’re going to take a deeper look at what they mean and what works best when.
AT: All-terrain tires are probably the most popular type of tread pattern for stock trucks. These are pretty much all-purpose tires. They’ll cruise down the highway without any rumble or wobble, you can cruise around town in any weather conditions with comfort, and they can come with aggressive tread patterns for some off-road uses. You can even find these tires ranging up to 35 inches in diameter, meaning you can still get that big truck look without compromising any drivability.
MT: Mud terrain tires are best suited for off-road applications. They have super aggressive tread patterns meant to bite into mud and give you as much traction as possible when you’re out 4-wheeling. Because of the aggressive tread pattern day to day use becomes compromised. They aren’t meant to work on hard surfaces like pavement, and they can be pretty noisy. It can be done, but it’s not recommended you use these tires on your daily driver. These tires can be massive ranging up to and beyond 40 inches in diameter.
All Season: All season tires are best intended for street use only. These are meant to perform best on pavement. As the name implies they can handle any road conditions all year round and will deliver best in handling capabilities and street drivability. They lack aggressive tread pattern so going rock crawling with your buddies isn’t the best way to use these tires. They can come up to a 33-inch selection, which maintains that beefy truck look GMC Sierras wear best.
