The 2004 Hummer Trucks H2 brought military-inspired presence into the early-2000s SUV market, pairing heavy-duty visual character with full-size street and trail capability. Buyers looking after one today often want to preserve that broad-shouldered stance while keeping the truck practical for real road use. For this exact H2, the primary tire fitment is a 315/70R17 radial on a 17-inch rim, so the main question is less about multiple factory sizes and more about choosing the right tire within that size. Wheel condition, actual wheel width, and any suspension or wheel changes deserve a careful look before replacing worn tires.
Which Tire Size Is Right for The 2004 Hummer Trucks H2
The 2004 Hummer Trucks H2 uses one primary tire size: 315/70R17. That is a radial tire fitted to a 17-inch rim, and the same size applies to the covered H2 Base sub-model. Since there is only one primary fitment to start from, the real decision is confirming your wheel setup and choosing a tire in the proper size that suits how the truck is used and presented.
315/70R17 is a metric radial size in which 315 identifies the nominal section width in millimeters, 70 is the aspect ratio, R marks radial construction, and 17 is the wheel diameter in inches. On the 2004 Hummer Trucks H2, this is the primary fitment size and it supports the truck's substantial factory-style footprint. The tire dimensions associated with this size include an overall diameter of 34.36 inches and a section width of 12.4 inches, which makes wheel and clearance confirmation especially important. It is the right starting point for maintaining proper proportions on an H2 that still uses its intended wheel diameter.
Tire fitment for the covered 2004 Hummer Trucks H2 sub-model is straightforward because the same primary size is used throughout. Checking the exact sub-model still helps confirm that you are starting from the correct 315/70R17 radial fitment before comparing replacement tires.

Frequently Asked Questions
Common questions for the 2004 Hummer Trucks H2 usually center on the 315/70R17 tire size, 17-inch rim fitment, radial sizing meaning, replacement selection, and the checks that matter before putting a heavy SUV back on the road.
Tire Size & Fitment
What tire size fits a 2004 Hummer Trucks H2?
The 2004 Hummer Trucks H2 uses a 315/70R17 tire size. This is a radial fitment and it is the primary size used for the covered H2 application, including the Base sub-model.
That makes the first step fairly simple: start with 315/70R17 and then verify that the truck still has the correct 17-inch wheel setup. Since many H2s have been modified over time, it is smart to confirm actual wheel dimensions, inspect for rubbing or clearance issues, and compare the replacement tire to the truck's present wheel and suspension configuration before installation.
What size rim does a 2004 Hummer Trucks H2 use?
The primary tire fitment for the 2004 Hummer Trucks H2 is built around a 17-inch rim. That matches the 315/70R17 tire size, where the final number in the size code identifies the wheel diameter.
Rim diameter is only part of the fitment picture, so it helps to confirm the actual wheels on the truck before buying replacement tires. An H2 with aftermarket wheels may still use a 17-inch diameter but differ in width or offset, and those changes can affect sidewall shape, steering clearance, and overall fit once a new tire is mounted.
Does the 2004 Hummer Trucks H2 Base use the same tire size?
Yes. The 2004 Hummer Trucks H2 Base uses the same 315/70R17 radial tire size as the covered H2 fitment. There is no separate primary size to sort through within this sub-model listing.
That consistency simplifies the search, but it does not remove the need to check the truck itself. Older SUVs are often fitted with replacement wheels, altered ride heights, or nonstandard tire setups, so the safest approach is to confirm the wheel diameter and overall clearance at the vehicle before choosing a new set in the original size.
Choosing the Right Tire
What should I consider when choosing a 315/70R17 tire for a 2004 Hummer Trucks H2?
Start with the correct primary size, which is 315/70R17 for the 2004 Hummer Trucks H2. From there, the main considerations are keeping the proper 17-inch fitment, matching the tire to the truck's current wheel setup, and choosing a replacement suited to how the H2 is actually driven and maintained.
A heavy SUV places real demands on tires, so condition and compatibility matter as much as the size code itself. Check the present wheel width, inspect for uneven wear that may point to suspension or alignment issues, and make sure the replacement tire works with the truck's actual clearance at full steering lock and through suspension movement.
How do I choose between available 315/70R17 tires for a 2004 Hummer Trucks H2?
The right comparison starts with fitment, not just appearance. Any 315/70R17 tire considered for a 2004 Hummer Trucks H2 should match the truck's 17-inch wheel diameter and suit the vehicle's present wheel, suspension, and use conditions.
Once size and wheel compatibility are confirmed, look closely at the overall condition of the truck and how it will be used. An H2 that sees mostly pavement, occasional trail use, or long periods of storage may call for different priorities, so it helps to compare tire construction details, service expectations, and how the mounted tire will sit on the wheels currently on the vehicle.
What rim-fitment details should I compare when choosing 2004 Hummer Trucks H2 tires?
For a 2004 Hummer Trucks H2, the key rim-fitment point is the 17-inch wheel diameter required by the 315/70R17 tire size. Beyond diameter, the wheel's actual width and offset can influence how the tire fits and how much room remains around steering and suspension components.
Those details matter because two wheels with the same diameter can still place the tire differently on the truck. A replacement tire should be evaluated with the real wheel setup in mind, especially if the H2 has aftermarket wheels, suspension changes, or signs of past rubbing that suggest the current combination deserves a closer check.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Hummer Trucks H2?
A period-style starting point for a 2004 Hummer Trucks H2 is the original-size approach: staying with the 315/70R17 radial fitment on the correct 17-inch wheel diameter. That preserves the broad, substantial stance associated with the truck without moving immediately into a different overall sizing direction.
Appearance still needs to be balanced against the vehicle's current setup and intended road use. If the H2 has nonstock wheels or suspension changes, the best-looking choice on paper may not sit correctly once mounted, so checking actual wheel dimensions and clearances helps keep the truck's visual character consistent and usable.
Does correct tire fitment matter for a 2004 Hummer Trucks H2 restoration?
Yes, correct tire fitment matters because the H2's visual presence depends heavily on tire proportion as well as wheel diameter. Using the proper 315/70R17 size helps maintain the truck's intended stance and keeps the restoration from looking undersized or mismatched at the corners.
Fitment also affects practicality, not just appearance. A restoration-minded owner should confirm the truck still wears the right wheel diameter, inspect wheel condition, and check for modifications that could change how a correctly sized tire sits within the wheel openings before putting the vehicle back into regular road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Hummer Trucks H2?
Yes. Wheel changes, suspension lifts, lowering, altered offsets, and body modifications can all affect how a 315/70R17 tire fits on a 2004 Hummer Trucks H2. Even when the size code stays the same, the tire's mounted position relative to fenders, steering components, and suspension parts can change.
That is why it helps to inspect the truck rather than relying only on the original fitment size. Turn the steering from lock to lock, look for past rubbing marks, and confirm the actual wheel dimensions before replacing tires so the new set works with the H2 as it sits today, not just as it left the factory.
What should I inspect before driving a 2004 Hummer Trucks H2 on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and the general state of the suspension and steering components. A 2004 Hummer Trucks H2 is a heavy vehicle, so uneven wear, looseness, or neglected chassis parts can affect how a fresh set of 315/70R17 tires performs once installed.
Tire pressure, alignment condition, and visible clearance at the inner fenders and suspension points also deserve attention. A careful walk-around after mounting, followed by a short low-speed check for vibration or rubbing, can catch problems early and helps confirm that the truck is ready for normal driving.
How should 315/70R17 tires on a collector-era 2004 Hummer Trucks H2 be maintained?
315/70R17 tires on a 2004 Hummer Trucks H2 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven tread wear, and protected from long periods of neglect. Low-use trucks can age tires out before wearing them out, especially when they spend much of their time parked.
Regular movement helps prevent flat spotting, and clean, dry storage away from prolonged sunlight and ozone sources can slow deterioration. It also pays to check for slow air loss and monitor tread condition before each driving season, since a vehicle that sits for extended periods can develop tire issues without accumulating many miles.
