The 1996 AM General Trucks Hummer came from a vehicle line known for its military roots, wide stance, and unmistakably heavy-duty road presence. Buyers looking after one today are often balancing authentic appearance with the realities of maintaining a large, specialized 4x4 that may see everything from show use to regular road driving. For this exact model, the primary tire fitment is a 37X12.50R16.5 radial, a flotation-style light truck size built around a 16.5-inch wheel. That keeps the tire decision focused less on multiple factory sizes and more on choosing the right radial within that fitment while confirming wheel condition, wheel type, and overall vehicle setup.
Which Tire Size Is Right for The 1996 AM General Trucks Hummer
The 1996 AM General Trucks Hummer uses one primary tire size: 37X12.50R16.5. It is a radial flotation-style light truck tire built for a 16.5-inch rim, and it appears across the covered sub-models here. That means the main decision is not which factory size fits, but whether the wheel setup is still correct and whether the tire chosen matches the vehicle's intended use, appearance, and condition.
The size 37X12.50R16.5 is a flotation-style truck designation that describes an approximately 37-inch overall tire diameter, a 12.50-inch section width, and a 16.5-inch rim diameter, with the R marking radial construction. On a 1996 AM General Trucks Hummer, that sizing reflects the vehicle's large-scale, off-road-oriented stance and specialized wheel package. Because this is already the primary radial fitment, the buyer's focus shifts to confirming the actual wheels on the truck and checking that width, clearance, and overall condition still support this size. That is especially important on vehicles that may have seen service use, aftermarket changes, or long-term storage.
Tire fitment is straightforward here because the covered 1996 AM General Trucks Hummer sub-models use the same primary tire size. Checking the exact wheel type still matters, since both versions rely on the same 37X12.50R16.5 radial fitment on a 16.5-inch rim.

Frequently Asked Questions
These 1996 AM General Trucks Hummer FAQs focus on the 37X12.50R16.5 fitment, 16.5-inch wheel requirements, sub-model consistency, and the checks that matter before putting a heavy collector-era truck back on the road.
Tire Size & Fitment
What tire size fits a 1996 AM General Trucks Hummer?
The 1996 AM General Trucks Hummer uses a 37X12.50R16.5 radial tire. This is a flotation-style light truck size that combines an approximate 37-inch overall diameter with a 12.50-inch section width and a 16.5-inch rim diameter.
That makes fitment relatively straightforward as long as the truck still has the proper wheel setup. The main thing to verify is that the wheels on the vehicle are actually 16.5-inch Hummer-spec wheels and that no previous owner changed wheel size, suspension height, or body clearance in a way that affects how this large tire sits and steers.
What size rim does a 1996 AM General Trucks Hummer use?
The primary tire fitment for the 1996 AM General Trucks Hummer is built around a 16.5-inch rim. That rim diameter is tied directly to the 37X12.50R16.5 tire size used on this vehicle.
Rim diameter should be confirmed before ordering any replacement tire because 16.5-inch wheels are distinct from more common 16-inch or 17-inch applications. A tire may look similar at a glance, but the bead seat must match the wheel exactly, and a truck with changed wheels needs to be measured by the wheel itself rather than assumed from the model year alone.
Do all 1996 AM General Trucks Hummer sub-models use the same tire size?
Yes. The covered 1996 AM General Trucks Hummer sub-models here, including the Base and the 1 Piece Steel Wheel version, use the same 37X12.50R16.5 radial tire size. There is no split primary tire size within these listed versions.
That consistency simplifies replacement, but the wheel configuration still deserves attention because the truck may have been modified over time. It is smart to confirm the actual wheel diameter and inspect for any aftermarket changes, especially on a vehicle this size where wheel width, tire clearance, and steering travel can all influence whether the replacement remains appropriate in real-world use.
Choosing the Right Tire
What should I consider when choosing a 37X12.50R16.5 tire for a 1996 AM General Trucks Hummer?
Start with the basic fitment facts: the correct size is 37X12.50R16.5 and the wheel diameter is 16.5 inches. Because this is a large radial flotation-size tire for a heavy-duty truck, the right choice begins with matching the correct size and construction before considering any other feature.
After that, look closely at how the Hummer is used. A truck kept mostly for collector use may prioritize a traditional appearance, while one driven regularly needs close attention to tire age, wheel condition, and overall setup. It also helps to confirm that the current wheels, suspension height, and clearance around the fenders and steering components still suit a tire of this diameter and width.
How do I choose between available 37X12.50R16.5 tires for a 1996 AM General Trucks Hummer?
Choosing between tires in the same 37X12.50R16.5 size comes down to matching the tire to the truck's current purpose and condition. Since the primary fitment itself does not change, the comparison should stay centered on proper wheel compatibility, radial construction, and whether the tire suits a restoration-minded truck or a more regularly driven example.
It is also worth checking the whole vehicle rather than just the sidewall. A Hummer that still wears original-style wheels may call for a different buying decision than one with later wheel changes or suspension work. Looking at age, storage history, steering clearance, and the truck's actual road use helps narrow the choice without drifting away from the correct original fitment size.
Why is it important to keep the correct 37X12.50R16.5 size on a 1996 AM General Trucks Hummer?
The 37X12.50R16.5 size defines more than just width or wheel diameter on a 1996 AM General Trucks Hummer. It is a large flotation-style radial that shapes the truck's stance, wheel relationship, and basic fitment envelope, so changing away from it can alter more than appearance alone.
Keeping the correct size helps avoid introducing unnecessary fitment questions on a vehicle that already uses a specialized wheel and tire package. Any move to a different diameter, width, or rim size should be treated as a custom setup rather than a routine replacement, with close attention paid to wheel compatibility, clearance through steering travel, and the overall condition of the suspension and brakes.
Restoration & Appearance
Which tire should I choose for a period-style 1996 AM General Trucks Hummer?
For a period-style 1996 AM General Trucks Hummer, the right starting point is the original-size 37X12.50R16.5 radial fitment on the proper 16.5-inch wheel. Staying with the correct size preserves the truck's intended proportions and avoids introducing a visibly different stance through an off-size replacement.
Appearance-minded buyers should also look at the truck as a whole rather than treating the tire as a stand-alone item. Wheel finish, wheel type, ride height, and overall tire condition all influence how authentic the finished vehicle feels. If exact historical presentation matters, marque-specific references and vehicle history can help guide the final choice without assuming every surviving truck is equipped the same way.
Does correct tire fitment matter for a 1996 AM General Trucks Hummer restoration?
Yes, correct tire fitment matters because the 1996 AM General Trucks Hummer has a very distinctive visual stance built around its large 37X12.50R16.5 radial tires and 16.5-inch wheels. Using the proper size helps maintain the truck's intended proportions and keeps the restoration from looking visibly off.
Fitment also affects how complete and usable the finished vehicle feels. A restoration can lose credibility quickly if the tire diameter, width, or wheel relationship looks wrong in the wheel opening. Even when the goal is road use rather than judged originality, confirming the proper wheel setup and avoiding improvised substitutions keeps the truck closer to its intended presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1996 AM General Trucks Hummer?
Yes. Even though the 1996 AM General Trucks Hummer uses a single primary size, modifications can still change whether that 37X12.50R16.5 tire works as intended on the vehicle. Wheel swaps, suspension changes, body alterations, and steering-component changes can all influence clearance and overall fitment behavior.
A truck of this size should be checked carefully if anything has been changed from its original setup. Measuring the actual wheel diameter, inspecting wheel width and backspacing, and looking at clearance at full steering lock are all worthwhile steps. Those checks matter even more on collector trucks that may have passed through several owners over the years.
What should I inspect before driving a 1996 AM General Trucks Hummer on new tires?
Before road use, inspect the wheels, lug hardware, valve stems, and overall tire condition, and confirm that the truck is actually wearing the correct 16.5-inch wheels for its 37X12.50R16.5 tires. It is also smart to check for brake drag, steering looseness, and any signs that the suspension or alignment needs attention.
A short, careful test drive after installation helps reveal rubbing, pull, vibration, or unusual behavior before the truck is taken farther from home. Because the Hummer is large and heavy, air pressure, bead seating, and visible sidewall condition deserve close attention. Any sign of cracking, bulging, or interference should be addressed before regular road use.
How should 37X12.50R16.5 tires on a collector 1996 AM General Trucks Hummer be maintained?
Collector-use 37X12.50R16.5 tires should be checked regularly for pressure loss, tread wear, sidewall cracking, bulges, and signs of age-related deterioration. Even a low-mileage 1996 AM General Trucks Hummer can develop tire issues simply from long storage, heavy curb weight, or exposure to heat and sunlight.
Good maintenance includes keeping the truck on the correct pressure, moving it often enough to avoid long-term flat spotting, and storing it away from prolonged moisture and ozone sources when possible. Periodic inspection matters more than mileage alone on a specialty vehicle like this, especially before a longer drive or after the truck has been sitting for an extended period.
