In 2004, Hummer Trucks stood for maximum visual presence and heavy-duty off-road image, with the civilian H1 carrying military-derived proportions and the H2 translating that attitude into a broader SUV market. Tire choice across 2004 Hummer Trucks is not shared across the range, because the H1 and H2 use different 17-inch radial sizes with very different overall proportions. The real decision starts with identifying whether you have an H1 or an H2, since size follows model here rather than a simple year-and-make-wide fitment rule. Once that is clear, the next step is confirming the exact size on your wheels before choosing the right replacement tire.
Which Tire Size Is Right for Your 2004 Hummer Trucks
Two tire sizes were used across 2004 Hummer Trucks, and they vary by model rather than carrying across the full range. Both sizes mount on 17-inch wheels, but the first step is still confirming whether you have an H1 or an H2 because each model uses its own distinct radial size. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2004|Fit(s): H1|Construction: Radial|Rim: 17 in
The 37X12.50R17 is a flotation-style radial size that uses a 37-inch overall diameter, a 12.50-inch nominal section width, and a 17-inch rim, and it is specific to the 2004 Hummer Trucks H1 rather than universal across the range. BFGoodrich offers this size with an RWL sidewall, and the available example carries an R speed rating with a 106 mph ceiling and a maximum load of 3,525 pounds at 50 psi. This is the size to choose if you are matching the H1's tall, wide stance and want a tire built around that model's heavy-duty footprint.
Year(s): 2004|Fit(s): H2|Construction: Radial|Rim: 17-in rim
The 315/70R17 is a metric radial size with a 315-millimeter section width, a 70-series aspect ratio, and a 17-inch rim, and it is specific to the 2004 Hummer Trucks H2. This size serves a different role in the range than the H1 flotation size, with a more conventional metric format familiar to later SUV buyers. If you own an H2, this is the size family to verify first before moving on to brand, tread style, and wheel-width compatibility.
Both sizes use a 17-inch rim diameter, but wheel-width compatibility should still be confirmed against the exact size and tire you plan to run.
2004 Hummer Trucks Models
Two models are covered for 2004 Hummer Trucks. They do not share the same tire size, so identifying whether you have an H1 or H2 matters before you narrow your choices. Select your model below to explore model-specific fitment history and tire options.
2004 Hummer Trucks H1
The 2004 Hummer Trucks H1 remained the closest civilian link to the original military Humvee theme, with massive proportions and a purpose-built off-road character that set it apart from nearly anything else on the road. Its tire fitment mounts on a 17-inch wheel and uses a tall flotation-style radial size that is central to the H1's distinctive stance.
The 2004 Hummer Trucks H2 brought Hummer styling and image into a more mainstream full-size SUV format, making it more accessible while still preserving the brand's bold, upright look. Its tires mount on a 17-inch wheel, but the H2 uses a metric radial size rather than the H1's flotation-type sizing.
One product is available across two tire sizes for 2004 Hummer Trucks vehicles. The 37X12.50R17 has one BFGoodrich radial with an RWL sidewall, while the 315/70R17 size should be confirmed by exact model before selecting a tire.
These FAQs cover the model-by-model size split across 2004 Hummer Trucks, how the H1 flotation size differs from the H2 metric size, and what to check for setup, storage, and highway use on low-mileage specialty SUVs.
Size Basics & Fitment
What tire sizes fit 2004 Hummer Trucks vehicles?
2004 Hummer Trucks vehicles use two different tire sizes depending on model. The H1 uses 37X12.50R17, while the H2 uses 315/70R17. Both sizes mount on 17-inch wheels, but they are not interchangeable year-and-make-wide fitments because each size belongs to a specific model. For the H1 size, the supported wheel-width range runs from 8.5 to 11.0 inches.
That means year and make alone are not enough to choose a tire for 2004 Hummer Trucks. Start by confirming whether you have an H1 or H2, then verify the exact size already on the vehicle and the wheel width you are working with. That approach is especially important on Hummer models, where overall tire proportions are a major part of appearance, clearance, and intended use.
What does 37X12.50R17 mean on a 2004 Hummer Trucks tire?
On a 2004 Hummer Trucks H1, 37X12.50R17 is a flotation-style radial size. The first number is the tire's overall diameter in inches, the second is the nominal section width in inches, the R indicates radial construction, and the last number is the wheel diameter in inches. In practical terms, it is a 37-inch-tall radial built for a 17-inch wheel.
That sizing format is different from modern passenger-car metric sizing, so it is easy to misread if you are more familiar with sizes like 315/70R17. On the H1, the tall overall diameter is a defining part of the vehicle's stance and clearance. Before replacing one, confirm the wheel width and compare the sidewall marking on the tire currently mounted to the truck.
Do all 2004 Hummer Trucks models use the same tire size?
No, 2004 Hummer Trucks models do not all use the same tire size. The H1 uses 37X12.50R17, while the H2 uses 315/70R17. Even though both fit 17-inch wheels, they differ significantly in sizing system, overall proportions, and model application.
That distinction matters because an H1 owner usually begins with a flotation-style off-road size, while an H2 owner begins with a metric SUV size. If you are replacing tires on a vehicle you did not order new, check the model badge, measure what is on the truck now, and verify the wheel before settling on a replacement path.
Buying the Right Tire
What sidewall styles are available for 2004 Hummer Trucks tires?
For 2004 Hummer Trucks, the 37X12.50R17 H1 size is available with an RWL sidewall, meaning raised white letters. That look fits the aggressive truck-and-SUV character many owners want, especially on a vehicle as visually bold as the H1. Sidewall style can matter almost as much as tread pattern on a Hummer because the tire is such a visible part of the overall stance.
If appearance is part of your decision, look at the truck from the side and decide whether you want a more period off-road presentation or a more understated look. Matching all five tires, including the spare, usually gives the cleanest result on a Hummer. Sidewall treatment will not change the basic fitment, but it absolutely changes how authentic or era-appropriate the finished vehicle feels.
What brands make tires for 2004 Hummer Trucks vehicles?
BFGoodrich is available in 37X12.50R17 for 2004 Hummer Trucks H1 applications, specifically in the All-Terrain T/A KO2 family. BFGoodrich has long been associated with off-road and truck use in the American market, so it suits the H1's rugged identity well. Brand choice matters on specialty SUVs because casing design, tread style, sidewall presentation, and speed rating can vary even when the size stays the same.
The most useful way to shop by brand on 2004 Hummer Trucks is to start with the model-specific size, then compare the exact tire's construction details and sidewall style. H1 owners looking for a purposeful off-road look will usually care about those details as much as the brand name itself. For H2 applications, begin by confirming the metric size before narrowing the field.
What is the difference between the BFGoodrich All-Terrain T/A KO2 and other tire approaches for 2004 Hummer Trucks?
For 2004 Hummer Trucks H1 fitment in 37X12.50R17, the BFGoodrich All-Terrain T/A KO2 is a radial tire with an R speed rating, a 106 mph ceiling, a 3,525-pound maximum load at 50 psi, an RWL sidewall, and a wheel-width range of 8.5 to 11.0 inches. Those details place it firmly in the modern all-terrain radial category rather than a vintage-style reproduction tire category.
That makes the comparison less about old-versus-new styling and more about matching the tire's real-world specifications to the H1's weight, intended use, and wheel. If you drive your Hummer regularly, those hard numbers matter more than marketing language. Confirm the tire's sidewall marking, wheel width, and load needs before you choose among different tread or brand directions.
Fitting & Setup
What rim width do 2004 Hummer Trucks tires require?
For 2004 Hummer Trucks H1 applications using 37X12.50R17, the supported rim-width range is 8.5 to 11.0 inches on a 17-inch wheel. That range is broad enough to cover many truck wheel setups, but it still needs to match the actual wheel on the vehicle. Wheel width affects sidewall shape, tread profile, and how the tire sits under load.
If you are replacing existing H1 tires, check the wheel specification before assuming any 17-inch wheel is suitable. If the truck has aftermarket wheels, that step becomes even more important. On the H2 side, confirm the exact wheel dimensions on the vehicle before choosing a 315/70R17 tire, since proper setup depends on more than wheel diameter alone.
Can the original 2004 Hummer Trucks wheels be used with both tire sizes?
Both 2004 Hummer Trucks tire sizes use a 17-inch wheel diameter, so they share that basic dimension. Even so, the H1's 37X12.50R17 and the H2's 315/70R17 are model-specific sizes, not interchangeable choices for the whole range. Diameter match alone does not mean the same wheel is appropriate across both vehicles.
The right way to think about it is model first, wheel details second, and tire size third. H1 and H2 wheels can differ in width and application even though both are 17-inch designs. If you are evaluating original wheels, verify the actual wheel width and compare it to the tire manufacturer's approved range before assuming cross-model compatibility.
Maintenance, Storage & Longevity
How should I store a 2004 Hummer Trucks when the tires are fitted?
A 2004 Hummer Trucks vehicle should be stored out of direct sunlight, away from ozone sources such as electric motors and battery chargers, and on a clean, dry surface. Keep the tires properly inflated during storage and move the vehicle periodically so the same contact patch is not carrying the full weight for months at a time. Radial tires generally tolerate storage better than older bias-ply designs, but they still age from heat, ultraviolet exposure, and inactivity.
If the truck will sit for an extended season, many owners either roll it occasionally or place it on stands to reduce long-term stress at the footprint. A heavy specialty SUV like a Hummer benefits from that extra attention because static load is substantial. Storage habits are one of the easiest ways to preserve sidewall condition and reduce vibration when the truck goes back on the road.
How long do tires on a 2004 Hummer Trucks typically last?
On a 2004 Hummer Trucks vehicle, tire life should be judged more by age and condition than by mileage alone. A collector or low-use truck may still have acceptable tread depth while the rubber itself has aged past its prime. As a working rule, begin evaluating tires closely around five to seven years of age and treat the ten-year point as a serious replacement threshold regardless of remaining tread.
Check the DOT date code on each tire and inspect for cracking, hardening, irregular wear, or impact damage. Hummers often accumulate fewer miles than modern daily drivers, which can make old tires look healthier than they really are. Replacing an aged tire before a long trip is usually the wiser decision than trying to extract every last mile from rubber that has spent years in storage.
How often should tires on a 2004 Hummer Trucks be inspected?
Tires on a 2004 Hummer Trucks vehicle should be inspected before every drive and again before any extended highway outing or trail trip. Look for sidewall cracking, cuts, bulges, uneven tread wear, punctures, and pressure loss. On a heavy SUV, early signs of trouble can become serious quickly if they are ignored.
A monthly close inspection is a good baseline even if the truck is parked most of the time. Pay extra attention after long storage, after airing down for off-road use, or after contact with curbs and rocks. Consistent inspections help catch wheel damage, valve-stem deterioration, and alignment-related wear before they turn into a larger drivability or safety problem.
Safety & Road Use
Are 2004 Hummer Trucks tires safe for highway driving?
Yes, 2004 Hummer Trucks tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their rating limits. The available 37X12.50R17 BFGoodrich tire for the H1 carries an R speed rating, which corresponds to a 106 mph ceiling. In real-world use, the broader limitations on an H1 or H2 are often the vehicle's weight, age, suspension condition, and braking behavior rather than pure tire speed potential.
Highway safety depends on the whole package working together, not on size alone. Keep pressures correct, inspect the tires regularly, and avoid treating an older specialty SUV like a modern performance vehicle. If the truck has been modified, lifted, or fitted with non-original wheels, those changes should be evaluated carefully because they can influence stability and tire loading at speed.
What inflation pressure should I use for 2004 Hummer Trucks tires?
For 2004 Hummer Trucks H1 applications in 37X12.50R17, the tire's maximum load figure is 3,525 pounds at 50 psi. That number is the tire's rated maximum pressure for its stated load, not automatically the pressure you should run in everyday service. Inflation pressure for normal driving should follow the vehicle manufacturer's recommendation first, then be checked against the tire maker's guidance for the exact product.
Do not transfer one tire's pressure figure to another size or assume that a heavier-looking tire always needs to be run near its maximum. Pressure that is too high or too low can affect ride quality, wear, and braking. The best routine is to begin with the vehicle recommendation, verify the tire's sidewall limits, and fine-tune only within safe, manufacturer-supported ranges.
What should I check before taking a 2004 Hummer Trucks on a longer drive?
Before taking a 2004 Hummer Trucks vehicle on a longer drive, inspect each tire for cracking, cuts, punctures, bulges, irregular wear, and proper inflation. Check the spare as well, since Hummer owners often overlook it until it is urgently needed. A visual walkaround should also include valve stems, wheel condition, and any signs that a tire has been rubbing or carrying load unevenly.
A longer drive in a specialty SUV is also the right time to think beyond the tires. Confirm that brakes, steering, suspension, and cooling are all ready for sustained use, especially if the truck spends much of its life parked. Good tire preparation supports the drive, but on a 2004 Hummer Trucks vehicle, the most trouble-free trip usually comes from treating the whole vehicle like the heavy, specialized machine it is.
