The 1994 GMC Trucks K1500 Suburban sits in the era when full-size SUVs were expected to handle family duty, towing, winter weather, and rougher back-road use without losing their long-wheelbase practicality. That broad-use character makes tire selection especially important on a Suburban, because the tire needs to suit both the truck’s stance and the way it is actually driven today. This model uses radial fitments in 225/75R16 and 245/75R16 on 16-inch rims. Current choices center on an all-terrain radial with raised white letter sidewalls, so the real decision is confirming the exact size on the vehicle and matching it to the wheel setup, intended use, and overall appearance you want.
Which Tire Size Is Right for The 1994 GMC Trucks K1500 Suburban
The 1994 GMC Trucks K1500 Suburban uses two primary tire sizes, and both are radial tires built for 16-inch wheels. Because Base and SLE models can use either size, the first step is not trim identification but confirming which wheel and tire size is already on the truck before choosing a replacement. Once that is settled, the decision becomes selecting the right overall footprint and wheel-width match.
225/75R16 is a metric radial size in which 225 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 16 is the wheel diameter in inches. On the 1994 GMC Trucks K1500 Suburban, this size delivers a standard modern radial format suited to the truck’s 16-inch wheel fitment. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth considering when the truck already wears the narrower original-style fitment or when wheel-width compatibility points you toward the 225-width tire.
245/75R16 follows the same metric radial format, with 245 indicating nominal section width in millimeters, 75 representing the aspect ratio, R marking radial construction, and 16 identifying the rim diameter. For the 1994 GMC Trucks K1500 Suburban, this is the wider of the two primary tire sizes and still uses the same 16-inch wheel diameter. In this fitment, the available option is a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. It is the size to evaluate when the truck already has the broader tire setup and the wheel width matches the requirements of the 245-size casing.
Tire fitment is straightforward across the covered 1994 GMC Trucks K1500 Suburban sub-models, because both Base and SLE can use the same two radial sizes. The key is confirming which of those two sizes is actually on the vehicle rather than assuming the trim level alone determines the tire choice.

1994 GMC Trucks K1500 Suburban Base
The 1994 GMC Trucks K1500 Suburban Base can use either of the two 16-inch radial tire sizes offered for this model. That means replacement selection starts with checking the truck’s current wheel and tire setup, then choosing the size that matches the intended stance, wheel width, and use.
The 1994 GMC Trucks K1500 Suburban SLE shares the same basic tire-fitment situation as the Base model, with both primary radial sizes available on 16-inch wheels. For tire selection, that puts the focus on verifying the existing size and wheel dimensions before comparing the available all-terrain replacement.
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 Trucks K1500 Suburban Tires for Sale
Available tires for the 1994 GMC Trucks K1500 Suburban center on BFGoodrich All-Terrain T/A KO2 radials in both primary 16-inch sizes. The main comparison points are 225 versus 245 width, raised white letter appearance, wheel-width compatibility, load capacity, and overall tire weight.
Common questions for the 1994 GMC Trucks K1500 Suburban usually come down to the two correct tire sizes, 16-inch rim fitment, how Base and SLE trims overlap, and what to inspect before putting a full-size SUV back on the road.
Tire Size & Fitment
What tire size fits a 1994 GMC Trucks K1500 Suburban?
The 1994 GMC Trucks K1500 Suburban uses two primary tire sizes: 225/75R16 and 245/75R16. Both are radial sizes for 16-inch wheels, and both Base and SLE sub-models can use either one, so this is not a case where one trim automatically gets one size and another trim gets the other.
The practical step is to confirm which size is already fitted to the truck and whether the wheels match that size’s width requirements. Since both sizes are valid for this Suburban, the real fitment question is the actual wheel-and-tire setup on the vehicle, especially if it has had replacement wheels or past tire changes.
What size rim does a 1994 GMC Trucks K1500 Suburban use?
The tire fitments for the 1994 GMC Trucks K1500 Suburban use a 16-inch rim diameter. Both 225/75R16 and 245/75R16 are built around that same 16-inch wheel size, so the wheel diameter stays consistent even though the two tires differ in section width and overall dimensions.
Wheel diameter is only part of the fitment picture, so it is still important to check actual wheel width before choosing between the two sizes. A 225/75R16 and a 245/75R16 do not share the same rim-width range, and that matters when replacing tires on a truck that may have been changed over the years.
Do all 1994 GMC Trucks K1500 Suburban sub-models use the same tire size?
Base and SLE versions of the 1994 GMC Trucks K1500 Suburban share the same overall tire-fitment range. Each can use 225/75R16 or 245/75R16, both in radial construction on 16-inch rims, so sub-model alone does not narrow the selection to a single tire size.
That shared fitment means the deciding factor is usually the truck’s existing wheel and tire combination, not the badge on the door. Looking at the current tire sidewall and measuring wheel width if needed is the best way to avoid choosing a replacement size that does not match the wheel setup already on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 225/75R16 or 245/75R16 tire for a 1994 GMC Trucks K1500 Suburban?
Start with the correct primary size for the truck, because the 1994 GMC Trucks K1500 Suburban can use either 225/75R16 or 245/75R16. Both are radial tires on 16-inch rims, but they differ in width and overall dimensions, so selecting the right one begins with matching the wheel-and-tire setup already on the vehicle.
After confirming size, compare wheel-width compatibility, load capacity, tire weight, and the type of driving the Suburban sees. A truck used for mixed pavement and light off-road travel may benefit from a different overall look and footprint than one kept closer to stock road use, even when both tires are valid fitments.
What sidewall styles are available for 1994 GMC Trucks K1500 Suburban tires?
The available products for the 1994 GMC Trucks K1500 Suburban use RWL sidewalls, meaning raised white letters. That gives the truck a more traditional light-truck and SUV appearance than a plain blackwall and suits the character of a 1990s full-size four-wheel-drive Suburban.
Sidewall style is still a presentation choice as much as a fitment issue, so it helps to think about how the truck is being kept. A raised white letter tire can look right at home on a stock or mildly upgraded Suburban, but the size and wheel match still matter more than appearance alone.
What tire series are available for the 1994 GMC Trucks K1500 Suburban?
The available tire series for the 1994 GMC Trucks K1500 Suburban is the BFGoodrich All-Terrain T/A KO2. It is offered in both primary sizes used on this vehicle, so the series itself remains consistent while the buyer chooses between the narrower 225/75R16 and the wider 245/75R16 fitment.
That keeps the selection process focused on size, wheel-width compatibility, load capacity, and overall truck use rather than sorting through multiple series with different personalities. For a Suburban that sees mixed road conditions, an all-terrain series makes practical sense, but the tire still needs to match the actual wheel setup on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1994 GMC Trucks K1500 Suburban?
A period-style approach for a 1994 GMC Trucks K1500 Suburban starts with staying in one of the two correct primary sizes: 225/75R16 or 245/75R16. Since both sizes were used on this model range, the more authentic-looking choice is usually the one that matches the truck’s existing wheel setup and overall stance.
Appearance should be balanced with practical fitment. A truck kept close to its original look may benefit from preserving the existing size format and wheel relationship, while one with wheel changes needs a more careful review of width and clearance. For exact restoration standards, vehicle-specific historical references remain the best guide.
How does tire construction affect the appearance of a restored 1994 GMC Trucks K1500 Suburban?
The 1994 GMC Trucks K1500 Suburban uses modern radial tire sizes, so keeping radial construction preserves the general visual character and road-going stance associated with the truck. In this case, construction change is less of a vintage bias-ply-versus-radial question and more about choosing the correct size and sidewall presentation.
Sidewall treatment plays a visible role, and the available option uses raised white letters for a distinctly 1990s truck look. On a restoration-oriented Suburban, that can influence the truck’s final presentation almost as much as the size itself, especially when paired with original-style wheels and ride height.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1994 GMC Trucks K1500 Suburban?
Yes, modifications can affect tire fitment on a 1994 GMC Trucks K1500 Suburban even when the tire size is one of the two correct primary options. Changes such as aftermarket wheels, altered wheel width, suspension lifts or lowering, and body or steering-component changes can all influence how a 225/75R16 or 245/75R16 sits on the truck.
That is why the current setup matters more than assumptions about stock configuration. Checking wheel diameter and width, then looking at clearance during steering and suspension movement, helps avoid problems that are not obvious while the truck is parked. A full-size SUV has more variables than a simple sidewall size stamp may suggest.
What should I inspect before driving a 1994 GMC Trucks K1500 Suburban on new tires?
Before putting a 1994 GMC Trucks K1500 Suburban back into regular road use on new tires, inspect the wheels for correct diameter and width, verify air pressure, and make sure the tires clear the suspension and bodywork at full steering lock. It also helps to confirm even mounting and that no tire rub appears under normal loading.
A Suburban often spends time parked or sees intermittent use, so the surrounding hardware deserves attention too. Looking over shocks, springs, steering components, and brake condition can prevent a new set of tires from being blamed for issues that really come from worn chassis parts or long periods of storage.
How should 225/75R16 or 245/75R16 tires on a collector 1994 GMC Trucks K1500 Suburban be maintained?
Tires on a collector-used 1994 GMC Trucks K1500 Suburban should be checked regularly for pressure loss, uneven wear, sidewall cracking, cuts, bulges, and tread condition. Since this truck uses radial 16-inch tires in either 225/75R16 or 245/75R16, keeping the correct pressure and maintaining even loading are basic parts of preserving tire life.
Storage habits matter on a low-use Suburban. Limiting prolonged exposure to heat, sunlight, moisture, and ozone sources can help protect the tires between drives, and occasional movement helps avoid long-term flat spotting. A tire can still look usable on a seldom-driven truck, so routine inspection remains more important than appearance alone.
