The 2001 AM General Trucks Hummer sits in a very specific corner of the SUV world, carrying military-derived presence, serious ground clearance, and the wide-track stance that made the civilian Hummer instantly recognizable. Tire choice matters here because the vehicle’s proportions, clearance, and wheel setup are a major part of how it looks and works. The 2001 AM General Trucks Hummer uses radial flotation-style light truck sizes, with 37X12.50R16.5 and 37X12.50R17 both associated with this model. That makes the decision less about moving between vintage constructions and more about confirming wheel diameter, then choosing the right radial tire style and specification. For a stock-looking truck or one that has been changed over time, wheel verification comes first.
Which Tire Size Is Right for The 2001 AM General Trucks Hummer
The 2001 AM General Trucks Hummer uses two primary tire sizes, and both are radial flotation-style light truck fitments. The key step is confirming whether the truck is on a 16.5-inch or 17-inch wheel, since both sizes share the same 37-inch overall diameter and 12.50-inch section width but require different rim diameters. Once wheel size is confirmed, the focus shifts to selecting the right radial tire within that fitment.
37X12.50R16.5 is a flotation-style light truck radial size that reads as an approximate 37-inch overall diameter, 12.50-inch section width, and fitment for a 16.5-inch rim. In practical terms, it keeps the tall, wide stance expected of a 2001 AM General Trucks Hummer while using modern radial construction rather than bias-ply. The biggest point to understand is that 16.5-inch wheel fitment is specific and cannot be treated the same as a 17-inch setup. This size should be chosen only after confirming the truck’s actual wheel diameter, especially on vehicles that may have been changed from their earlier wheel and tire combination.
37X12.50R17 uses the same flotation-style sizing logic: about 37 inches tall, 12.50 inches wide, and built for a 17-inch rim. It is a radial fitment suited to the 2001 AM General Trucks Hummer and preserves the oversized off-road truck look that defines the vehicle. Available product choice in this size includes BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls, adding a distinctly truck-oriented appearance as well as a recognizable all-terrain series. This size is the right starting point when the Hummer is already on 17-inch wheels and the buyer wants to compare radial product details rather than change wheel diameter.
Fitment is straightforward at the sub-model level because the covered 2001 AM General Trucks Hummer Base can use either of the two radial tire sizes associated with this model. The important step is not trim identification so much as confirming which wheel diameter is actually on the truck before choosing tires.

Tire Size & Fitment
What tire size fits a 2001 AM General Trucks Hummer?
The 2001 AM General Trucks Hummer is associated with two tire sizes: 37X12.50R16.5 and 37X12.50R17. Both are radial flotation-style light truck sizes, and both share the same approximate 37-inch overall diameter and 12.50-inch section width while using different rim diameters.
The practical difference is the wheel itself. A truck on 16.5-inch rims needs 37X12.50R16.5, while a truck on 17-inch rims needs 37X12.50R17. Since many Hummers have seen wheel changes over time, the safest first step is checking the wheel diameter on the vehicle before selecting a tire.
What size rim does a 2001 AM General Trucks Hummer use?
A 2001 AM General Trucks Hummer can use either a 16.5-inch rim or a 17-inch rim, depending on which of its two associated tire sizes is on the truck. The 37X12.50R16.5 size requires a 16.5-inch wheel, and the 37X12.50R17 size requires a 17-inch wheel.
That distinction matters because the two wheel diameters are not interchangeable. Even though both tire sizes share the same height and width format, the bead seat diameter is different. Checking the actual wheel stamping or measuring the installed wheel is the right move before comparing tire options or replacing a worn set.
Why does the 2001 AM General Trucks Hummer have more than one tire size?
The 2001 AM General Trucks Hummer has more than one tire size because it is associated with two different wheel diameters: 16.5 inches and 17 inches. Both fitments stay within the same large flotation-style radial theme, using a 37-inch overall diameter and 12.50-inch section width.
For the buyer, this is less about choosing between a narrow tire and a wide tire and more about confirming the exact wheel already on the vehicle. A Hummer that has been modified, restored, or converted at some point may not still have its earlier setup, so wheel diameter should be verified before ordering replacements.
Choosing the Right Tire
What should I consider when choosing a 37X12.50R17 tire for a 2001 AM General Trucks Hummer?
Start with confirmed 17-inch wheel fitment, then compare the tire’s construction, rim-width range, load specification, sidewall style, and overall intended use. In this size, the available BFGoodrich All-Terrain T/A KO2 is a radial tire with an 8.5- to 11.0-inch rim-width range and a 3,525-lb capacity at 50 psi.
That combination makes it important to match the tire not only to the wheel diameter, but also to the wheel width actually on the truck. Appearance can matter too, since raised white letter sidewalls create a different look than a plain black sidewall. Clearance and vehicle setup should still be checked on any Hummer with changes from stock.
What sidewall styles are available for 2001 AM General Trucks Hummer tires?
Among the available products for this fitment, the visible sidewall style is RWL, or raised white letter. That style appears on the 37X12.50R17 BFGoodrich All-Terrain T/A KO2 and gives the tire a traditional off-road truck presentation that suits the Hummer’s aggressive, utilitarian character.
Sidewall choice affects appearance more than fitment, but it still matters to owners who want the truck to look a certain way. A raised white letter tire reads differently from a more subdued black sidewall. Once wheel diameter is confirmed, sidewall treatment becomes one of the clearer style decisions in the buying process.
What brands offer tires for the 2001 AM General Trucks Hummer?
BFGoodrich is represented in the current product selection for the 2001 AM General Trucks Hummer, specifically in the 37X12.50R17 size. The available tire is the All-Terrain T/A KO2, a radial light truck tire with raised white letter sidewalls and specifications suited to a large-format Hummer fitment.
Brand matters mainly as part of the overall product comparison rather than as a shortcut to the right choice. The more important questions are whether the tire matches the truck’s wheel diameter, whether the wheel width falls within the tire’s approved range, and whether the appearance and use case fit the way the Hummer is driven.
Restoration & Appearance
Which tire should I choose for a period-style 2001 AM General Trucks Hummer?
A period-style choice for a 2001 AM General Trucks Hummer starts with keeping the truck in one of its associated 37-inch radial flotation sizes, either 37X12.50R16.5 or 37X12.50R17 depending on wheel diameter. Staying within that tall, wide radial format preserves the visual stance that is central to the vehicle’s character.
From there, appearance comes down to the exact wheel setup and sidewall treatment you want. On the 17-inch fitment, a raised white letter tire creates a more traditional off-road truck look. For owners pursuing strict historical accuracy, vehicle-specific photos and marque references are worth checking before deciding on final presentation.
How does tire construction affect the appearance of a restored 2001 AM General Trucks Hummer?
On the 2001 AM General Trucks Hummer, construction is less about bias-ply versus radial appearance and more about preserving the correct large flotation-style radial look. Both primary fitments are radial, so the visual character comes from the tire’s overall height, width, tread personality, and sidewall treatment rather than an older construction change.
That means restoration-minded buyers should focus on keeping the proper 37-inch visual footprint and matching the tire to the wheel diameter already on the truck. Sidewall styling can shift the final presentation noticeably, especially on a truck with a strong military-inspired design language, even when the basic size remains correct.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2001 AM General Trucks Hummer?
Yes. Modifications can affect tire fitment on a 2001 AM General Trucks Hummer even when the tire size appears correct on paper. Wheel changes, altered offset, suspension work, ride-height adjustments, and body or fender changes can all influence how a 37-inch tire sits and clears during steering and suspension movement.
A modified truck should be checked carefully before replacing tires. Confirm the actual wheel diameter first, then verify wheel width, steering clearance, and any close points around the body or suspension. Large flotation sizes leave less room for assumption, so a Hummer with aftermarket parts deserves a more careful fitment review.
What should I inspect before driving a 2001 AM General Trucks Hummer on new tires?
Before road use, inspect the wheel diameter and width, verify proper inflation, and make sure the tires clear the suspension, steering components, and bodywork through full movement. It is also wise to check lug torque, valve stems, and overall tire condition, especially on a heavy vehicle running large flotation-size radials.
A short, careful test drive helps confirm that nothing rubs at low-speed steering lock or over bumps. After that first drive, recheck inflation and look for any unusual contact marks. On a Hummer, the tire’s size and weight make those early inspection steps especially important before longer trips or off-road use.
How should tires on a collector-era 2001 AM General Trucks Hummer be maintained?
Tires on a low-use 2001 AM General Trucks Hummer should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, bulges, and signs of aging. Even a radial tire that sees limited mileage can deteriorate with time, especially on a vehicle that spends long stretches parked between drives.
Good storage habits help preserve them. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources can slow visible aging. It also helps to maintain proper inflation and move the vehicle periodically rather than letting the tires sit in one position for long periods under full vehicle weight.
