The 2009 GMC Trucks Sierra 3500 HD sits in the heavy-duty pickup world where payload, towing confidence, and wheel setup matter as much as day-to-day road use. Buyers looking at this generation usually care about more than appearance alone, because tire choice affects stance, load capability, and how the truck is equipped for single-rear-wheel or dual-rear-wheel service. This Sierra 3500 HD uses radial tires, with fitments including 265/70R17, 265/75R16, 225/75R17, and 225/75R16 depending on configuration. Available choices focus on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The key is matching the truck’s exact sub-model and wheel diameter before comparing load-rated options.
Which Tire Size Is Right for The 2009 GMC Trucks Sierra 3500 HD
Four primary tire sizes apply to the 2009 GMC Trucks Sierra 3500 HD, and the right one depends on the exact sub-model and whether the truck uses a 16-inch or 17-inch wheel. Some SLE, SLT, and WT models use either 265/70R17 or 265/75R16, while dual-rear-wheel versions use narrower 225-series sizes. Before choosing a tire, confirm both the truck’s sub-model and the wheel diameter actually on the vehicle.
In 265/70R17, the 265 is the tire’s section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2009 GMC Trucks Sierra 3500 HD, this size is one of the primary fits for certain single-rear-wheel SLE, SLT, and WT configurations. Available choices center on BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls and multiple load-rated versions. It is a strong size to evaluate when the truck already carries 17-inch wheels and needs a heavier-duty light-truck radial fitment.
The 265/75R16 size uses a 265-millimeter section width, a 75-series profile, radial construction, and a 16-inch rim. For the 2009 GMC Trucks Sierra 3500 HD, this is another primary fitment used on certain single-rear-wheel SLE, SLT, and WT trucks rather than the dually models. The available product in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and an LT-rated specification. This size deserves attention when the truck is equipped with 16-inch wheels and the goal is to stay with the proper heavy-duty tire format.
A 225/75R17 tire has a 225-millimeter section width, a 75-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2009 GMC Trucks Sierra 3500 HD, this narrower fitment is tied to certain dual-rear-wheel SLE and SLT configurations rather than the wider single-rear-wheel setups. Product selection should be approached with the truck’s dually wheel arrangement in mind, since the size serves a different fitment role than the 265-series tires. Confirming the truck’s exact DRW configuration and wheel diameter is the practical first step before comparing replacement options.
In the 225/75R16 size, 225 indicates section width in millimeters, 75 is the aspect ratio, R means radial, and 16 is the wheel diameter in inches. This size applies to the 2009 GMC Trucks Sierra 3500 HD WT (DRW), making it a configuration-specific fitment rather than a broad fit across the entire model line. The available option is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls in an LT-rated construction. It is the size to focus on when a work-oriented dually truck retains its 16-inch wheel setup and needs the correct narrower tire format.
Sub-model fitment matters on the 2009 GMC Trucks Sierra 3500 HD because tire size changes between single-rear-wheel and dual-rear-wheel versions, and wheel diameter can change within the same trim. Checking the exact SLE, SLT, or WT configuration keeps a 265-series single-wheel fitment from being confused with a narrower dually tire.

2009 GMC Trucks Sierra 3500 HD SLE
The 2009 GMC Trucks Sierra 3500 HD SLE uses either a 265/70R17 or 265/75R16 radial tire, so wheel diameter is the first thing to confirm on the truck. Once that is established, tire selection becomes a matter of choosing the appropriate load-rated option within the correct single-rear-wheel size.
The 2009 GMC Trucks Sierra 3500 HD SLE (DRW) uses a 225/75R17 radial tire, which separates it clearly from the wider 265-series single-rear-wheel SLE fitments. Tire selection should stay focused on the truck’s dually wheel arrangement and 17-inch setup before comparing any replacement options.
The 2009 GMC Trucks Sierra 3500 HD SLT shares the same two primary radial fitments as other single-rear-wheel trims: 265/70R17 or 265/75R16 depending on wheel diameter. That means the right replacement starts with verifying whether the truck carries 16-inch or 17-inch wheels, then matching load range and intended use.
The 2009 GMC Trucks Sierra 3500 HD SLT (DRW) uses the 225/75R17 radial size rather than the wider single-rear-wheel tire options. For replacement, the important step is keeping the dually-specific size and confirming the existing 17-inch wheel setup before comparing available tire specifications.
The 2009 GMC Trucks Sierra 3500 HD WT uses either 265/70R17 or 265/75R16 radial tires, so this trim does not point to one universal size by itself. The practical decision is confirming the actual wheel diameter on the truck and then selecting the correct heavy-duty radial in that matching size.
The 2009 GMC Trucks Sierra 3500 HD WT (DRW) uses a 225/75R16 radial tire, making it distinct from both the single-rear-wheel WT and the 17-inch dually fitments in other trims. Tire selection should begin with that 16-inch dually setup, then move to load range, rim-width compatibility, and overall condition of the wheel assembly.
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.

Tire Size & Fitment
What tire size fits a 2009 GMC Trucks Sierra 3500 HD?
The 2009 GMC Trucks Sierra 3500 HD uses four primary tire sizes: 265/70R17, 265/75R16, 225/75R17, and 225/75R16. The correct size depends on the truck’s exact sub-model and whether it is a single-rear-wheel or dual-rear-wheel configuration.
A wider 265-series tire and a narrower 225-series dually tire do not serve the same fitment role, so the first step is identifying the truck’s trim and wheel setup. After that, confirm the wheel diameter on the truck itself, since some SLE, SLT, and WT models use either a 16-inch or 17-inch rim.
What size rim does a 2009 GMC Trucks Sierra 3500 HD use?
The 2009 GMC Trucks Sierra 3500 HD uses either a 16-inch or 17-inch rim, depending on the tire size and configuration. The 265/70R17 and 225/75R17 sizes use 17-inch wheels, while 265/75R16 and 225/75R16 use 16-inch wheels.
That makes wheel diameter one of the most important checks before replacing tires on this truck. A Sierra 3500 HD owner should verify the actual wheel installed on the vehicle rather than assume all trims use the same rim, especially when the truck may have been changed from its original wheel setup.
Do all 2009 GMC Trucks Sierra 3500 HD sub-models use the same tire size?
No. The 2009 GMC Trucks Sierra 3500 HD has different tire sizes across its covered sub-models. Single-rear-wheel SLE, SLT, and WT trims use either 265/70R17 or 265/75R16, while dually versions use 225/75R17 or 225/75R16 depending on the specific trim.
That difference matters because the correct replacement is tied to both the sub-model and the wheel arrangement. A buyer who starts with trim alone can still choose the wrong size if wheel diameter or dually status is overlooked, so both details should be confirmed before comparing tire specifications.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 GMC Trucks Sierra 3500 HD?
Start with the correct primary size for the truck’s exact configuration: 265/70R17, 265/75R16, 225/75R17, or 225/75R16. From there, compare construction, wheel diameter, rim-width compatibility, and load-capacity specifications that match how the Sierra 3500 HD is actually used.
A truck used for hauling or towing may need a different load-rated version than one driven mostly unloaded, even within the same size family. Matching the tire to the vehicle’s wheel setup and intended use is more important than choosing by appearance alone, especially on a heavy-duty pickup.
What sidewall styles are available for 2009 GMC Trucks Sierra 3500 HD tires?
The available products for the 2009 GMC Trucks Sierra 3500 HD use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the applicable sizes.
Sidewall style affects the truck’s visual presentation more than its basic fitment, but it still matters to many buyers. Some owners prefer the traditional off-road look of raised white letters, while others may mount the tires with the white lettering turned inward if the wheel and tire combination allows that presentation.
What brands offer tires for the 2009 GMC Trucks Sierra 3500 HD?
The available tire options for the 2009 GMC Trucks Sierra 3500 HD are from BFGoodrich. The product line represented here is the All-Terrain T/A KO2, offered in the applicable 16-inch and 17-inch radial truck sizes used on this model.
That means the main comparison is not between multiple brands, but between the correct size and the specific load-rated version within that family. Once the proper tire size is confirmed, the buyer can focus on rim-width range, load capacity, and whether the tire matches the truck’s single-rear-wheel or dually setup.
Restoration & Appearance
Which tire should I choose for a period-style 2009 GMC Trucks Sierra 3500 HD?
A period-style choice for a 2009 GMC Trucks Sierra 3500 HD starts with staying in the correct original fitment family for the truck’s configuration, whether that means 265/70R17, 265/75R16, 225/75R17, or 225/75R16. Keeping the proper size and wheel diameter preserves the truck’s intended stance more effectively than chasing a different look.
This generation is modern enough that radial truck tires remain the natural fitment direction, so appearance usually comes down to sidewall treatment and overall tire character rather than bias-ply versus radial decisions. Owners who want a more authentic presentation should verify the truck’s exact wheel and trim setup before changing sizes.
How does tire construction affect the appearance of a restored 2009 GMC Trucks Sierra 3500 HD?
On a 2009 GMC Trucks Sierra 3500 HD, construction does not create a bias-ply-versus-radial styling choice because the primary fitments are radial tires. The visual effect comes more from the correct section width, sidewall profile, wheel diameter, and details such as raised white letter sidewalls.
A restored or carefully kept truck can look noticeably different when the tire size drifts away from its proper fitment family, even if the wheel still bolts on. Keeping the right 16-inch or 17-inch radial size for the truck’s exact configuration does more for an authentic overall appearance than changing to a mismatched profile.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 GMC Trucks Sierra 3500 HD?
Yes. Modifications can change tire fitment on a 2009 GMC Trucks Sierra 3500 HD even when the tire size sounds close to the original specification. Aftermarket wheels, wheel-offset changes, suspension lifts or lowering, and body modifications can all affect clearance and how the tire sits on the truck.
A modified truck should be checked for wheel diameter, wheel width, and clearance at full steering lock and suspension travel before replacement tires are chosen. That step is especially important on a Sierra 3500 HD because its fitment already varies by sub-model, wheel size, and single-rear-wheel versus dual-rear-wheel configuration.
What should I inspect before driving a 2009 GMC Trucks Sierra 3500 HD on new tires?
Before driving a 2009 GMC Trucks Sierra 3500 HD on new tires, inspect the wheels for damage, confirm the tire size matches the truck’s configuration, and check inflation pressure against the tire and vehicle requirements. Lug torque, valve stems, and general wheel condition also deserve attention before road use.
A short follow-up inspection after initial driving is worthwhile on a heavy-duty truck because it can reveal air loss, rubbing, or uneven seating that was not obvious at installation. The owner should also watch for clearance issues at the front suspension and under load, particularly if the truck has aftermarket wheels or suspension changes.
How often should tires on a 2009 GMC Trucks Sierra 3500 HD be inspected?
Tires on a 2009 GMC Trucks Sierra 3500 HD should be inspected regularly, not just when tread looks worn. A heavy-duty pickup benefits from routine checks for air pressure, uneven wear, sidewall cuts, cracking, bulges, and any signs of rubbing or abnormal contact with suspension or body components.
Inspection becomes even more important when the truck tows, carries heavy loads, or spends long periods parked between uses. A quick visual check before longer trips and a more careful inspection at regular service intervals can help catch problems early, especially on dually setups where fitment and spacing are more demanding.
