We’ve put together this comprehensive guide to help you figure out what kind of setup you need in order to properly handle the different trails and terrain you’ve been eyeing up. We’ll also include some examples from our gallery of what other Sierra 2500 owners have equipped in order to help give you an idea of what yours could look like when its finished.

Stock Wheel & Tire Fitment for the Second Generation GMC Sierra 2500

When we’re talking about stock wheel and tire sizes for the second generation GMC Sierra 2500, the only option that the truck came off the production line with is a 245/75 tire combined with a 16x6.5 wheel size. The bolt pattern that came on the Sierra 2500 is a 8x6.5 pattern, which is important to remember when you’re looking for wheels. You’ll have to make sure that any wheels you’re looking to equip your Sierra with fit that bolt pattern, otherwise you’ll need to use an adapter in order to get the correct fit.

So, when looking at tires and wheels for your Sierra 2500 off-roader, you’re going to want the combination of bigger tires and smaller wheels in order to take full advantage of your build’s full potential. This combination will give your truck the ground clearance and durability to overcome uneven terrain while protecting the truck’s critical components. Think tire sizes between 33-40 inches in height and wheels 17-20 inches in diameter. Now take that and combine it with a suspension lift that’s 3 inches or higher, and you’ll have the proper height to navigate any kind of terrain or trail with ease. Another thing you’ll want to keep in mind is your suspension’s geometry. You’ll want to make sure that your suspension is properly aligned before taking your truck out. If it’s not aligned, you can cause massive damage to your rig’s suspension.
