The 2002 GMC Trucks Sierra 1500 HD sits in an era when heavy-duty half-ton pickups were built to bridge everyday drivability with serious towing and work use. It carries the larger, sturdier personality that defined early-2000s full-size GMC trucks, so tire choice matters for both stance and real-world utility. This Sierra 1500 HD uses a 245/75R16 radial tire on a 16-inch rim, keeping fitment straightforward across the covered sub-models. Available choices focus less on changing size and more on selecting the right tread character, sidewall presentation, and load-capable construction. For an unmodified truck, the main goal is confirming the wheel setup and matching the tire to how the truck will actually be used.
Which Tire Size Is Right for The 2002 GMC Trucks Sierra 1500 HD
The 2002 GMC Trucks Sierra 1500 HD uses one primary tire size: 245/75R16, a radial fitment for a 16-inch rim. That same size is shared across the covered SLE and SLT sub-models, so the decision is less about multiple factory-type sizes and more about choosing the right tire within that fitment, while confirming the truck still has the correct wheel setup.
245/75R16 is a modern metric radial size in which 245 identifies the tire's nominal section width in millimeters, 75 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On the 2002 GMC Trucks Sierra 1500 HD, this is the primary fitment and it suits the truck's work-oriented, heavy-duty character. The available choice in this size uses BFGoodrich's All Terrain TA KO2 series with a raised white letter sidewall. It is the size to use when the truck retains its correct 16-inch wheel setup and the goal is preserving proper overall fitment for regular road and light truck use.
Tire fitment is straightforward on the 2002 GMC Trucks Sierra 1500 HD because the covered sub-models share the same primary size. Checking the exact sub-model still helps confirm that the truck has not been altered with different wheels or a non-stock tire package over time.

2002 GMC Trucks Sierra 1500 HD SLE
The 2002 GMC Trucks Sierra 1500 HD SLE uses the same 245/75R16 radial tire size as the other covered configuration. That keeps tire selection focused on choosing the right tread style, sidewall presentation, and load-capable product rather than sorting through multiple primary fitments.
The 2002 GMC Trucks Sierra 1500 HD SLT also uses 245/75R16 radial tires, so fitment remains consistent within this model range. Selection comes down to matching the truck's actual wheel setup and intended road or utility use instead of choosing between different original-type sizes.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2002 GMC Trucks Sierra 1500 HD Tires for Sale

These FAQs focus on the 2002 GMC Trucks Sierra 1500 HD's 245/75R16 fitment, 16-inch wheel compatibility, product selection, appearance details, and the checks worth making before putting a work-capable collector-era truck back into regular road use.
Tire Size & Fitment
What tire size fits a 2002 GMC Trucks Sierra 1500 HD?
The 2002 GMC Trucks Sierra 1500 HD uses a 245/75R16 radial tire. That size applies across the covered SLE and SLT sub-models, making the primary fitment question simpler than on trucks that used multiple factory-type sizes.
The practical next step is confirming that the truck still has the correct 16-inch wheels and has not been changed to a different wheel package over the years. If the Sierra has aftermarket wheels, suspension changes, or a different load-use pattern than stock, those factors should be checked before choosing a replacement tire.
What size rim does a 2002 GMC Trucks Sierra 1500 HD use?
The primary tire fitment for the 2002 GMC Trucks Sierra 1500 HD is built around a 16-inch rim. The available 245/75R16 product in this fitment is intended for a 16-inch wheel and carries a compatible rim-width range of 6.5 to 8.0 inches.
Rim diameter is the first measurement to confirm before replacing tires, because a 16-inch tire must be mounted on a 16-inch wheel. Width matters too, especially on a truck that may have seen wheel swaps, so checking both diameter and actual wheel width helps avoid mounting or clearance problems.
Do all 2002 GMC Trucks Sierra 1500 HD sub-models use the same tire size?
The covered 2002 GMC Trucks Sierra 1500 HD sub-models use the same primary tire size. Both the SLE and SLT are fitted with 245/75R16 radial tires, so there is no sub-model split between different listed sizes here.
That consistency makes shopping easier, but it does not remove the need to inspect the truck itself. Older pickups are often updated with different wheels, off-road tires, or suspension changes, and those modifications can affect the tire that is appropriate even when the original-type sub-model fitment remains the same.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2002 GMC Trucks Sierra 1500 HD?
Start with the correct size, which is 245/75R16, and make sure the tire matches the truck's 16-inch wheel setup. For this Sierra 1500 HD, the available option also brings a truck-oriented load specification of 3,042 lbs at 80 psi, which is an important part of the selection picture.
From there, focus on how the truck is used. A Sierra that sees highway driving, light hauling, or mixed on-road and unpaved use may benefit from a different tread character than a truck kept mainly for occasional cruising, so wheel width, intended use, and overall tire condition should guide the final choice.
What sidewall styles are available for 2002 GMC Trucks Sierra 1500 HD tires?
The available 245/75R16 fitment for the 2002 GMC Trucks Sierra 1500 HD includes an RWL sidewall, meaning raised white letters. That gives the truck a more assertive, period-appropriate light-truck look than a plain blackwall presentation.
Sidewall appearance matters more than many buyers expect because it changes the truck's visual character even when the size stays the same. Choosing between sidewall treatments is largely an appearance decision, but it still makes sense to keep size, construction, and wheel compatibility as the first priorities.
What brands offer tires for the 2002 GMC Trucks Sierra 1500 HD?
The current product selection for the 2002 GMC Trucks Sierra 1500 HD includes BFGoodrich in the 245/75R16 size. That option is part of the All Terrain TA KO2 series and uses radial construction for the truck's primary fitment.
Brand alone should not be the only deciding factor. It is more useful to look at the full package, including size accuracy, tire series, sidewall style, load specification, and the wheel-width range the tire is designed to work with on a 16-inch rim.
Restoration & Appearance
Which tire should I choose for a period-style 2002 GMC Trucks Sierra 1500 HD?
A period-style approach starts with the correct 245/75R16 size and radial construction, since that is the primary fitment for the 2002 GMC Trucks Sierra 1500 HD. Keeping the truck on the proper size preserves the visual balance between sidewall height, wheel diameter, and the Sierra's heavy-duty stance.
Appearance then comes down to the type of tire presentation you want on the truck. An all-terrain design with a more traditional light-truck look can suit the era well, but buyers aiming for exact originality should compare tire details against original sales literature, window-sticker documentation, or marque-specific reference material.
How does tire construction affect the appearance of a restored 2002 GMC Trucks Sierra 1500 HD?
On a 2002 GMC Trucks Sierra 1500 HD, radial construction is part of the proper visual and functional character because 245/75R16 is already a modern radial size. The tire's overall look is shaped less by switching construction and more by tread pattern, sidewall treatment, and maintaining the correct proportions on a 16-inch wheel.
That means restoration-minded owners should pay close attention to presentation details such as raised white letters versus a more subdued sidewall look. A tire can look right for the truck's era without making any claim of exact factory originality, and that distinction matters when authenticity is part of the goal.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 GMC Trucks Sierra 1500 HD?
Yes, modifications can change what works on a 2002 GMC Trucks Sierra 1500 HD even though the primary fitment is 245/75R16. Wheel swaps, changes in wheel width or offset, leveling kits, lifts, lowering, and brake or suspension alterations can all affect clearance and mounting suitability.
A truck that has been changed from its original wheel setup should be measured before new tires are selected. Steering clearance, suspension travel, and space at the fenders all deserve attention, especially on a heavier-duty pickup where tires may also be expected to handle towing, cargo, or rougher road conditions.
What should I inspect before driving a 2002 GMC Trucks Sierra 1500 HD on new tires?
Look over the wheels, valve stems, lug hardware, and the general condition of the suspension and steering components before putting a 2002 GMC Trucks Sierra 1500 HD back on the road with new tires. Tire pressure should also be set appropriately, and the mounted tire should match the truck's 16-inch wheel size and width.
A short inspection drive is worthwhile after installation to check for rubbing, vibration, or any sign that the truck's alignment or suspension needs attention. On an older pickup, it also helps to inspect the spare, monitor air retention over the first several days, and recheck the wheel fasteners after initial use.
How should 245/75R16 tires on a collector-era 2002 GMC Trucks Sierra 1500 HD be maintained?
245/75R16 tires on a low-use 2002 GMC Trucks Sierra 1500 HD should be kept properly inflated and inspected regularly for cracking, cuts, bulges, uneven wear, and signs of slow air loss. A truck that spends long periods parked can age its tires out before it wears them out.
Storage conditions matter as much as mileage on collector-minded vehicles. Keeping the truck away from prolonged sun, excessive heat, standing moisture, and ozone-producing equipment helps preserve the tires, and occasional checks of tread condition and sidewall health are smart before any longer trip or seasonal return to road use.
