The 1993 GMC Vans G3500 sits in the final years of the traditional full-size GM van era, a time when these vans served everything from family hauling to commercial duty and conversion-van travel. Buyers looking at one today are often balancing utility, period character, and dependable road manners. For this exact model, the primary fitment is a 225/75R16 radial on a 16-inch rim, and that same size carries across the covered sub-model range. Tire choice is less about sorting through multiple factory sizes and more about selecting the right radial type, sidewall presentation, and load-capable setup for how the van is actually used.
Which Tire Size Is Right for The 1993 GMC Vans G3500
The 1993 GMC Vans G3500 uses one primary tire size: 225/75R16, a radial tire built for a 16-inch rim. That fitment stays consistent across the covered Rally, Vandura, extended, and heavy-duty-suspension versions, so the main decision is choosing the right tire within that size, including sidewall style, load-capable construction, and overall intended use.
A 225/75R16 size uses a nominal section width of 225 millimeters, a 75-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 1993 GMC Vans G3500, that means a modern radial fitment rather than an older bias-ply format, which suits the van’s practical, load-carrying role. Available options in this size include BFGoodrich’s All Terrain TA KO2 with raised white letter styling. This size is the right starting point when the goal is to keep the van on its proper rim diameter while matching the tire’s character to passenger, utility, or light truck use.
Tire fitment is straightforward across the covered 1993 GMC Vans G3500 sub-models because each one uses the same 225/75R16 radial size. Checking the exact sub-model still matters when evaluating wheel condition, load needs, and how the van will actually be driven or equipped.

1993 GMC Vans G3500 Rally
The 1993 GMC Vans G3500 Rally uses the same 225/75R16 radial fitment as the rest of the covered range. That keeps tire selection focused on choosing the right radial design, sidewall look, and load-capable product for the van’s condition and intended road use.
The 1993 GMC Vans G3500 Rally Ext. also uses 225/75R16 radial tires on a 16-inch rim. Selection comes down to choosing a tire that matches the van’s actual wheel setup, passenger or cargo use, and the look you want on an extended-body vehicle.
The 1993 GMC Vans G3500 Rally Ext. (DRW) uses the same 225/75R16 radial size. On a dual-rear-wheel van, tire selection should include a careful check of the wheel setup, spacing, and service demands before settling on a specific product.
The 1993 GMC Vans G3500 Rally STX carries the 225/75R16 radial fitment shared across this model line. That lets the decision center on tire type and appearance rather than alternate primary sizes, while still confirming the van’s wheels and overall setup before installation.
The 1993 GMC Vans G3500 Vandura uses 225/75R16 radials, giving it the same primary tire fitment as the Rally variants. For a working or restored Vandura, the key is selecting a tire in the correct size that suits the van’s real-duty use and wheel compatibility.
The 1993 GMC Vans G3500 Vandura Ext. stays with the 225/75R16 radial size. That makes fitment simple at the size level, but it is still worth checking wheel width, vehicle loading, and body or suspension changes that can affect clearance on an extended van.
The 1993 GMC Vans G3500 Vandura w/H.D. Suspension also uses the 225/75R16 radial size. Tire selection should reflect the van’s heavier-duty role by confirming that the wheel and tire combination matches its service needs rather than choosing by appearance alone.
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 1993 GMC Vans G3500 Tires for Sale
Available 225/75R16 choices for the 1993 GMC Vans G3500 focus on radial truck-style fitment rather than multiple vintage constructions. The current option is a BFGoodrich All Terrain TA KO2 with raised white letter sidewalls and a 6.0- to 7.0-inch rim-width range.
These FAQs focus on the 1993 GMC Vans G3500’s 225/75R16 fitment, 16-inch rim requirement, sub-model consistency, product selection, and the practical checks that matter before putting a full-size van back on the road.
Tire Size & Fitment
What tire size fits a 1993 GMC Vans G3500?
The 1993 GMC Vans G3500 uses a 225/75R16 radial tire. That size applies across the covered sub-models, including Rally, Rally Ext., Rally Ext. (DRW), Rally STX, Vandura, Vandura Ext., and Vandura w/H.D. Suspension.
That makes size selection fairly simple, but the job is not finished once the number matches. It is still smart to confirm that the van still has 16-inch wheels, that wheel width matches the tire requirement, and that any commercial use, conversion equipment, or suspension changes have not altered the fitment needs.
What size rim does a 1993 GMC Vans G3500 use?
The primary tire fitment for the 1993 GMC Vans G3500 is built around a 16-inch rim. The 225/75R16 size itself confirms that rim diameter, and the available product in this fitment is intended for a 16-inch wheel.
Rim diameter should be verified directly on the van before choosing tires, especially on older full-size vans that may have seen wheel swaps over the years. Diameter is only one part of the picture, so checking wheel width matters too, since the available 225/75R16 product calls for a 6.0- to 7.0-inch rim width.
Do all 1993 GMC Vans G3500 sub-models use the same tire size?
Yes. The covered 1993 GMC Vans G3500 sub-models all use the same 225/75R16 radial tire size. That includes the Rally and Vandura families, extended versions, the Rally Ext. (DRW), and the Vandura w/H.D. Suspension model.
Shared tire size simplifies replacement, but it does not erase the need to inspect the actual van. A dual-rear-wheel setup, heavy-duty use, aftermarket wheels, or a long-stored vehicle can still affect what should be checked before mounting tires, especially wheel condition, spacing, and the tire’s suitability for how the van will be driven.
Choosing the Right Tire
What should I consider when choosing a 225/75R16 tire for a 1993 GMC Vans G3500?
Start with the correct size, 225/75R16, and make sure the tire is built for a 16-inch wheel with the proper width range. The available option in this fitment is a radial BFGoodrich All Terrain TA KO2, so the selection centers on a truck-style tire rather than sorting through multiple vintage constructions.
The next step is matching the tire to the van’s real use. A lightly driven passenger van, a working cargo setup, and a conversion or travel van can all place different demands on the same tire size, so load capacity, wheel compatibility, ride expectations, and overall condition of the vehicle should guide the final choice.
What sidewall styles are available for 1993 GMC Vans G3500 tires?
The available 225/75R16 product for the 1993 GMC Vans G3500 uses an RWL sidewall, which means raised white letters. That gives the van a more truck-oriented appearance than a plain blackwall and can suit owners who want a more assertive period-appropriate 1990s look.
Sidewall style should still be treated as an appearance choice within the correct size, not as the first fitment priority. Once the tire size, rim match, and service needs are covered, the sidewall treatment becomes a useful finishing detail that can lean more work-truck, utility, or enthusiast depending on how the van is presented.
What brands offer tires for the 1993 GMC Vans G3500?
The current product choice in the 1993 GMC Vans G3500 fitment is from BFGoodrich. It is offered in the 225/75R16 size as an All Terrain TA KO2 radial, giving this van a recognizable light-truck tire option within its correct primary sizing.
With a single brand option visible in this fitment, selection becomes more about whether that tire’s character matches the van’s use than about comparing multiple manufacturers. Wheel width, load demands, ride expectations, and the van’s overall setup are more important here than chasing brand variety for its own sake.
Restoration & Appearance
Which tire should I choose for a period-style 1993 GMC Vans G3500?
A period-style approach starts with keeping the 225/75R16 size and 16-inch rim fitment that belongs on the 1993 GMC Vans G3500. Since the available option is a modern radial truck tire, the decision is less about vintage construction and more about whether that tire’s look and duty rating suit the van’s intended presentation.
Some owners want a clean stock-van appearance, while others prefer a more utility-focused or off-road-influenced look that still stays within the correct size. If exact restoration detail matters, checking period brochures, marque references, or vehicle-specific history can help confirm whether the visible sidewall style matches the appearance goal.
Does correct tire fitment matter for a 1993 GMC Vans G3500 restoration?
Yes, correct tire fitment matters because tire size has a major effect on how a restored 1993 GMC Vans G3500 sits, fills the wheel opening, and presents itself overall. Staying with the proper 225/75R16 size helps preserve the van’s intended stance while keeping the restoration grounded in the right fitment foundation.
Appearance is only part of the story on a full-size van. Correct size also supports sensible wheel compatibility and road-use preparation, which matters whether the van is a careful survivor, a detailed restoration, or a refreshed driver. Even on an appearance-focused build, the wheel setup and tire condition should be checked before regular use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 GMC Vans G3500?
Yes. Even though the 1993 GMC Vans G3500 uses a 225/75R16 tire as its primary fitment, modifications can change what actually works on the van. Wheel swaps, altered suspension height, conversion equipment, and body changes can all influence clearance, steering travel, and overall compatibility.
A van that still appears stock can also have changes hidden behind hubcaps or under the body, so measuring the installed wheels is worthwhile before replacing tires. On dual-rear-wheel versions especially, checking spacing and wheel configuration is important because the correct size alone does not confirm that every setup is the same.
What should I inspect before driving a 1993 GMC Vans G3500 on new tires?
Before road use, inspect the wheels for damage or corrosion, confirm that the tires match the van’s 16-inch wheel setup, and check inflation carefully. It is also wise to look over suspension and steering components, since worn hardware can make even correctly sized new tires feel unsettled or wear unevenly.
A full-size van places real demand on its tires, so the inspection should extend beyond the tire itself. Lug hardware, brake condition, alignment, and signs of rubbing deserve attention, particularly on vehicles that have sat for long periods or carry passengers, tools, or camper-style equipment on a regular basis.
How should 225/75R16 tires on a collector 1993 GMC Vans G3500 be maintained?
Collector-use tires on a 1993 GMC Vans G3500 should be checked regularly for pressure, tread condition, sidewall cracking, bulges, cuts, and signs of slow air loss. Even when mileage stays low, tires still age, and a large van can put noticeable stress on them simply from weight and long periods of sitting.
Storage conditions make a difference, so it helps to keep the van away from prolonged heat, direct sunlight, and moisture when possible. Routine inspection before every longer drive is a good habit, especially if the van is used seasonally, stored for part of the year, or carries more weight than a lightly used hobby vehicle.
