The 2009 Hummer Trucks H2 came from an era when full-size SUVs leaned hard into bold proportions, off-road image, and heavy-duty presence. Its wide stance and substantial body make tire choice more than a cosmetic decision, because the tire has a major effect on ride height, visual balance, and road manners. This H2 uses a 315/70R17 radial tire, a modern metric size on a 17-inch rim that suits the truck’s large-scale footprint. Since the fitment is straightforward, the real choice centers on selecting the right tire within that size and confirming compatibility if the vehicle has aftermarket wheels or suspension changes.
Which Tire Size Is Right for The 2009 Hummer Trucks H2
The 2009 Hummer Trucks H2 uses one primary tire size: 315/70R17, and it is a radial fitment on a 17-inch rim. That same size carries across the covered H2 sub-model, so the main decision is not choosing between multiple factory-style sizes, but making sure the tire matches the truck’s wheel setup, intended use, and overall stance.
315/70R17 is a metric radial size where 315 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2009 Hummer Trucks H2, this size delivers the broad, tall tire profile that fits the vehicle’s substantial proportions and 17-inch wheel package. Because the fitment is already modern radial, the key comparison is less about vintage construction and more about confirming wheel width, overall tire dimensions, and how the tire suits a stock or modified H2. That matters especially on trucks with changed ride height or aftermarket wheels.
Sub-model fitment is simple for the 2009 Hummer Trucks H2 because the covered configuration uses the same primary tire size. Checking the exact sub-model still matters, but there is no split here between different stock tire sizes or rim diameters.

Frequently Asked Questions
Common 2009 Hummer Trucks H2 tire questions usually center on 315/70R17 fitment, 17-inch rim compatibility, sub-model consistency, and what to inspect before putting a large SUV back on the road.
Tire Size & Fitment
What tire size fits a 2009 Hummer Trucks H2?
The 2009 Hummer Trucks H2 uses a 315/70R17 tire. This is a radial metric size, and it is the primary fitment for the covered H2 application.
That means the first step is not sorting through multiple stock sizes, but confirming that the truck still has the correct 17-inch wheel setup for 315/70R17 tires. On an H2, aftermarket wheels, suspension lifts, leveling kits, or other changes can affect how that size sits in the wheel opening and how much clearance remains at full steering lock.
What size rim does a 2009 Hummer Trucks H2 use?
The primary tire fitment for the 2009 Hummer Trucks H2 is built around a 17-inch rim. The 315/70R17 size ends in 17, which identifies the wheel diameter in inches.
Wheel diameter is the non-negotiable starting point because a 17-inch tire must mount to a 17-inch wheel. It is still smart to verify the actual wheel on the truck, especially if it has had custom wheels installed, since diameter alone does not settle every fitment detail. Width, offset, and brake clearance can also influence how a large tire works on an H2.
Do all 2009 Hummer Trucks H2 sub-models use the same tire size?
The covered 2009 Hummer Trucks H2 sub-model fitment is consistent. The H2 Base uses the same 315/70R17 radial tire size as the core 2009 H2 application.
That simplifies replacement because there is no split here between different primary sizes or different rim diameters. Even so, checking the truck in front of you still matters. A used H2 may already be wearing non-stock wheels or tires, and that can change what clears the suspension, how the tire fills the wheel opening, and whether a return to 315/70R17 is the right move.
Choosing the Right Tire
What should I consider when choosing a 315/70R17 tire for a 2009 Hummer Trucks H2?
Start with the correct size, which is 315/70R17 for the 2009 Hummer Trucks H2. Since this is already a modern radial fitment, the main concerns are matching the tire to a 17-inch wheel and selecting a tire that suits the truck’s intended use, appearance, and current wheel-and-suspension setup.
A large SUV like the H2 puts more emphasis on wheel width, section width, and clearance than many passenger cars do. It helps to check how close the existing tires sit to suspension components and fender liners, especially on a modified truck. Load capability, overall tire dimensions, and how much of the original stance you want to preserve should all be part of the decision.
How do I choose between available 315/70R17 tires for a 2009 Hummer Trucks H2?
The best way to compare 315/70R17 tires for a 2009 Hummer Trucks H2 is to begin with fitment basics, then narrow the choice by use. A tire that looks right on a stock-height H2 may not be the same choice for one used more often on pavement or one wearing aftermarket wheels.
After size and rim diameter are confirmed, compare the tire’s physical dimensions and any wheel-compatibility details that affect how it sits on the truck. The H2’s broad proportions make small changes more noticeable than on many SUVs. Owners who want a fuller, original-style stance often pay close attention to how the tire fills the wheel opening and whether steering clearance remains comfortable.
What rim-fitment details matter when choosing 2009 Hummer Trucks H2 tires?
For a 2009 Hummer Trucks H2, the key rim-fitment detail starts with wheel diameter: the tire size is 315/70R17, so the wheel must be 17 inches in diameter. Beyond that, wheel width and offset can affect how the tire mounts and how much room it has around suspension and body components.
Those details become especially important on trucks that no longer have their original wheels. A tire can share the correct diameter and still create problems if the wheel pushes it too far inward or outward. On an H2, that can influence steering clearance, fender clearance, and overall stance, so checking the actual wheel dimensions before buying helps avoid an expensive mismatch.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Hummer Trucks H2?
A period-style 2009 Hummer Trucks H2 should begin with the correct stock-size fitment, which is 315/70R17. Because the H2 was built in the modern radial era, staying with the proper radial size is the clearest starting point for preserving the truck’s intended visual proportions.
Appearance on an H2 is tied closely to scale, so the tire’s overall stance matters almost as much as the raw size code. A tire that is too narrow, too short, or mounted on a wheel with a very different offset can change the truck’s look quickly. Owners aiming for a restoration-oriented presentation usually benefit from keeping close to the original size and wheel relationship.
Does correct tire fitment matter for a 2009 Hummer Trucks H2 restoration?
Correct tire fitment matters on a 2009 Hummer Trucks H2 restoration because the truck’s design depends heavily on the proper tire-to-wheel proportion. The stock-size 315/70R17 radial helps maintain the broad, substantial stance associated with the H2’s original presentation.
Restoration-oriented buyers should look beyond simple wheel diameter and verify that the truck has not drifted away from its intended setup through oversized wheels, altered suspension, or mismatched tires. Even when the vehicle is not being restored to a formal show standard, returning to the proper fitment can improve visual balance and make the truck look more coherent from every angle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Hummer Trucks H2?
Yes, modifications can affect tire fitment on a 2009 Hummer Trucks H2 even when the nominal tire size remains 315/70R17. Changes such as aftermarket wheels, different wheel offset, suspension lifts, leveling kits, lowered ride height, or body trimming can all alter how that tire clears the truck.
A modified H2 should be checked at full steering lock and through normal suspension movement before settling on a replacement tire. The tire may sit closer to the inner wheelwell, suspension parts, or outer fender than expected. That is why the actual wheel-and-suspension setup matters just as much as the factory size code when the truck has been customized.
What should I inspect before driving a 2009 Hummer Trucks H2 on new tires?
Before driving a 2009 Hummer Trucks H2 on new tires, inspect the wheels for damage, confirm that the tires are mounted on the correct 17-inch rims, and verify that inflation is set appropriately for the tire and vehicle setup. A quick visual check of tread, sidewalls, and valve stems is also worthwhile.
On a large SUV, it also helps to look for rubbing marks, uneven old-tire wear, or signs of alignment and suspension issues before the first longer drive. Those clues can reveal problems that a fresh set of tires will not solve by itself. After installation, recheck clearances and air pressure once the truck has been driven and the tires have settled in.
How should 315/70R17 tires on a collector 2009 Hummer Trucks H2 be maintained?
315/70R17 tires on a collector 2009 Hummer Trucks H2 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of heat, direct sunlight, and ozone exposure during storage. Low annual mileage does not stop tires from aging.
A collector H2 often sits longer than a daily driver, so maintenance should include checking for air loss and flat spotting before road use. Moving the truck occasionally, keeping the tires clean, and watching for age-related hardening can help preserve both appearance and serviceability. Any tire that shows structural damage or severe aging deserves closer evaluation before the vehicle returns to the road.
