The 1994 GMC Vans G3500 sits in the final years of the traditional full-size rear-wheel-drive van era, serving everything from passenger hauling to commercial duty with the heavy-duty character buyers expected from a one-ton GMC. Tire choice on this van is refreshingly straightforward, because the covered G3500 sub-models use a single primary size: 225/75R16 radial on a 16-inch rim. That keeps the focus on selecting the right tire within the size rather than sorting through multiple factory fitments. Available options lean toward modern truck-oriented radial construction, including a raised white letter all-terrain choice. Before changing anything, confirm the van's actual wheel setup and intended use.
Which Tire Size Is Right for The 1994 GMC Vans G3500
The 1994 GMC Vans G3500 uses one primary tire size: 225/75R16. It is a radial fitment on a 16-inch rim, and that same size carries across the covered Rally and Vandura sub-models. For most owners, the decision is not which primary size fits, but which 225/75R16 tire best matches the van's wheel width, appearance, and intended road use.
225/75R16 is a metric radial size in which 225 identifies the nominal section width in millimeters, 75 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On the 1994 GMC Vans G3500, this is the core fitment format for a heavy-duty full-size van that benefits from a modern radial tire layout. Available choices in this size include BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. It is the size to evaluate when keeping the van on its proper 16-inch wheel setup and choosing a tire that suits passenger, utility, or mixed-use driving.
Tire fitment is straightforward across the covered 1994 GMC Vans G3500 sub-models, because each one uses the same 225/75R16 radial size. Checking the exact sub-model still matters when confirming that the van has retained its original-style wheel diameter and has not been altered over time.

1994 GMC Vans G3500 Rally
The 1994 GMC Vans G3500 Rally uses the same 225/75R16 radial fitment found across the covered lineup. That keeps tire selection focused on choosing the right tire style and wheel-width match rather than sorting through multiple size options.
The 1994 GMC Vans G3500 Rally (Gas) stays with the 225/75R16 radial size on a 16-inch wheel. Selection comes down to choosing a tire that suits the van's actual use and confirming that the wheels still match the intended fitment.
The 1994 GMC Vans G3500 Rally STX also uses 225/75R16 radial tires. With no alternate primary size in this coverage, the practical step is comparing tire characteristics within that size and making sure the van's current wheel setup has not changed.
The 1994 GMC Vans G3500 Vandura (Diesel) uses the same 225/75R16 radial fitment as the other covered sub-models. That makes replacement simpler, but wheel width, load needs, and any past commercial-use modifications should still be checked before selecting a tire.
The 1994 GMC Vans G3500 Vandura (Gas) remains on the single 225/75R16 radial size used throughout this group. Tire choice is mainly about selecting the right product within the size and verifying that the van still wears the correct 16-inch wheels.
The 1994 GMC Vans G3500 Vandura Ext. uses 225/75R16 radial tires as its primary fitment. For an extended van, it is especially worth checking wheel condition, tire age, and operating load before settling on a replacement in the same size.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1994 GMC Vans G3500 Tires for Sale
Available 225/75R16 tires for the 1994 GMC Vans G3500 focus on modern radial truck use rather than vintage-style appearance. Current product choice includes a BFGoodrich All Terrain TA KO2 with raised white letter sidewalls and a 6.0 to 7.0 inch rim-width range.
Common questions for the 1994 GMC Vans G3500 usually center on the correct 225/75R16 size, 16-inch rim fitment, product selection, and what to inspect before putting a heavy-duty full-size van back on the road.
Tire Size & Fitment
What tire size fits a 1994 GMC Vans G3500?
The 1994 GMC Vans G3500 uses 225/75R16 tires. This is a radial fitment on a 16-inch rim, and it applies across the covered Rally, Rally (Gas), Rally STX, Vandura (Diesel), Vandura (Gas), and Vandura Ext. sub-models.
That makes replacement simpler than on vehicles with multiple factory sizes, but size alone is not the only check. Confirm that the van still has 16-inch wheels, that the wheel width matches the tire requirement, and that previous commercial or custom modifications have not changed the fitment.
What size rim does a 1994 GMC Vans G3500 use?
The covered 1994 GMC Vans G3500 fitment uses a 16-inch rim with its 225/75R16 tire size. An available tire in this size is built for a 16-inch wheel and carries a recommended rim-width range of 6.0 to 7.0 inches.
Rim diameter is the first thing to verify before ordering replacement tires, especially on older vans that may have seen wheel swaps over the years. Checking width matters too, because a tire can share the right diameter but still be a poor match if the wheel is outside the proper width range.
Do all 1994 GMC Vans G3500 sub-models use the same tire size?
Yes. The covered 1994 GMC Vans G3500 sub-models all use the same 225/75R16 radial tire size. That shared fitment includes the Rally, Rally (Gas), Rally STX, Vandura (Diesel), Vandura (Gas), and Vandura Ext. versions.
Even with a shared size, it is still smart to inspect the van itself before replacing tires. Older full-size vans are often used for work, towing, or conversions, so wheel changes, suspension wear, or body modifications can affect how a replacement tire behaves once mounted and aired.
Choosing the Right Tire
What should I consider when choosing a 225/75R16 tire for a 1994 GMC Vans G3500?
Start with the correct size, 225/75R16, and make sure the tire is appropriate for a heavy-duty van application. Construction is radial here, so the main comparison points become wheel-width compatibility, load capability, sidewall style, and whether the tire's character suits highway, utility, or mixed-use driving.
A 1994 GMC Vans G3500 can lead a hard working life, so the replacement decision should match the van's actual role rather than its badge alone. Check the wheel width, look at the vehicle's current condition and cargo use, and avoid choosing only by appearance if the van still sees serious road duty.
What sidewall styles are available for 1994 GMC Vans G3500 tires?
The available 225/75R16 option for the 1994 GMC Vans G3500 uses an RWL sidewall, meaning raised white letters. That gives the van a more truck-oriented visual style than a plain blackwall and can suit period aftermarket tastes from the 1990s without changing the tire size itself.
Sidewall style should be treated as an appearance choice after the basic fitment is confirmed. If the van is being kept close to a plain commercial presentation, the visual effect may matter more than on a casual-use passenger van, but wheel compatibility and load suitability still come first.
What brands offer tires for the 1994 GMC Vans G3500?
BFGoodrich is represented in the available 225/75R16 fitment for the 1994 GMC Vans G3500. The current product offering in this size is the All Terrain TA KO2, a radial tire with raised white letter sidewalls aimed at truck and utility use.
When brand choice is narrow, the more useful comparison becomes whether the available tire matches the van's needs. Look closely at wheel-width range, load figure, construction, and tread character, then consider whether the van is used mainly for highway travel, occasional hauling, or more varied service.
Restoration & Appearance
Which tire should I choose for a period-style 1994 GMC Vans G3500?
For a period-style 1994 GMC Vans G3500, the starting point is staying with the proper 225/75R16 radial size on a 16-inch wheel. That preserves the fitment direction of the van while letting the owner choose a tire whose visual character and intended use make sense for the vehicle.
A raised white letter sidewall can give the van a distinctly 1990s truck-and-utility flavor, while overall wheel and tire proportions matter just as much as branding. If exact restoration authenticity matters, compare the van against period photos, sales literature, and marque-specific references before settling on final appearance details.
How does tire construction affect the appearance of a restored 1994 GMC Vans G3500?
The 1994 GMC Vans G3500 uses a radial tire fitment, so keeping radial construction maintains the visual stance and size format associated with the van's era. In this case, appearance differences are more likely to come from tread style and sidewall treatment than from switching between bias-ply and radial designs.
That means a restoration-minded owner should pay close attention to the look of the mounted tire rather than treating the size code alone as the whole answer. Sidewall lettering, overall presence on the wheel, and whether the tire looks appropriately commercial or utility-oriented all influence the finished presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1994 GMC Vans G3500?
Yes. Even though the primary fitment is 225/75R16, modifications can change how that size works on a 1994 GMC Vans G3500. Aftermarket wheels, altered wheel width, suspension changes, lowered stance, or body conversions can all affect clearance and the tire's relationship to the van.
A used one-ton van often has a history that is not obvious at first glance, so measuring the current setup is worth the effort. Confirm wheel diameter and width, look for rubbing marks, and inspect steering and suspension travel before assuming the original-size tire remains trouble-free on the vehicle.
What should I inspect before driving a 1994 GMC Vans G3500 on new tires?
Before driving on new tires, inspect the wheels for damage or corrosion, confirm the valve stems are in good condition, and make sure the 16-inch rims are the correct width for the chosen 225/75R16 tire. It also helps to check alignment condition, brake components, and any obvious suspension wear.
A fresh set of tires cannot correct worn steering parts or poor wheel condition, and those problems can quickly affect ride quality and tread wear. Once the tires are mounted, verify pressure, listen for vibration on the first drive, and recheck for any signs of contact after the van has been loaded.
How should 225/75R16 tires on a collector or low-use 1994 GMC Vans G3500 be maintained?
225/75R16 tires on a low-use 1994 GMC Vans G3500 should be checked regularly for air loss, tread wear, cracking, bulges, and cuts, even if the van is driven only occasionally. Storage conditions matter too, because heat, sunlight, moisture, and long stationary periods can age tires faster than mileage suggests.
Moving the van periodically, maintaining proper inflation, and keeping the tires clean helps preserve both condition and drivability. It is also wise to inspect the spare and to look over the sidewalls before any longer trip, since older full-size vans often spend long stretches parked between uses.
