The 1989 GMC Trucks V2500 Suburban sits in the heavy-duty end of GM's square-body truck era, a time when Suburbans were expected to haul people, cargo, and towing duties with equal confidence. For owners keeping one on the road today, tire selection matters as much for stance and utility as it does for everyday drivability. This model uses a 235/85R16 radial tire on a 16-inch rim, giving the page a straightforward fitment story centered on one primary size. Available choices focus less on changing size and more on selecting the right tire character, sidewall treatment, and rim-width compatibility for the truck's intended use.
Which Tire Size Is Right for The 1989 GMC Trucks V2500 Suburban
The 1989 GMC Trucks V2500 Suburban uses one primary tire size: 235/85R16, a metric radial mounted on a 16-inch rim. That same size carries across the covered sub-models here, so the decision is less about sorting through multiple fitments and more about choosing the right tire within that size for appearance, load capability, wheel compatibility, and how the Suburban is actually driven.
The 235/85R16 size is a metric radial format: 235 is the nominal section width in millimeters, 85 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On a 1989 GMC Trucks V2500 Suburban, that sizing supports the truck's heavy-duty character while staying within its primary 16-inch wheel fitment. Available options in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter styling and a published rim-width range of 6.0 to 7.5 inches. That makes wheel-width confirmation an important part of choosing the right tire.
Tire fitment is straightforward across the covered 1989 GMC Trucks V2500 Suburban sub-models because both use the same 235/85R16 radial size. Even so, confirming the exact sub-model and wheel setup still helps when comparing tire appearance, load specifications, and wheel compatibility.
This 1989 GMC Trucks V2500 Suburban passenger configuration uses the same 235/85R16 radial fitment as the other covered version. Tire selection therefore comes down to choosing the right product within that size and confirming the wheel still matches the tire's intended rim-width range.
The DRW version shown here also uses a 235/85R16 radial tire, so the primary size remains consistent. The practical step is verifying the actual wheel arrangement on the truck before purchase, especially if it has been modified or no longer wears its original wheel setup.
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.

Tire Size & Fitment
What tire size fits a 1989 GMC Trucks V2500 Suburban?
The 1989 GMC Trucks V2500 Suburban uses a 235/85R16 radial tire. That size appears across the covered passenger and DRW sub-models here, making the primary fitment question relatively simple compared with vehicles that split across several wheel and tire combinations.
Even with one main size, it is still worth confirming the truck's actual wheel setup before replacing tires. Many older Suburbans have seen wheel changes, suspension work, or mixed replacement parts over the years, so checking the installed rim diameter and wheel width helps keep the next tire choice aligned with the vehicle's current configuration.
What size rim does a 1989 GMC Trucks V2500 Suburban use?
The primary tire fitment for the 1989 GMC Trucks V2500 Suburban is built around a 16-inch rim. The available 235/85R16 product in this application also carries a stated rim-width range of 6.0 to 7.5 inches, which gives a useful reference point when confirming wheel compatibility.
Rim diameter is the first check, but wheel width matters too. A 16-inch wheel that falls outside the tire's approved width range can change the way the tire mounts and sits, so it is smart to verify both measurements on the truck rather than assuming every 16-inch wheel is automatically suitable.
Do all 1989 GMC Trucks V2500 Suburban sub-models use the same tire size?
The covered 1989 GMC Trucks V2500 Suburban sub-models both use the same 235/85R16 radial tire size. That means the passenger version and the DRW version shown here share the same primary tire-size designation rather than splitting into separate fitments.
Shared size does not remove the need to inspect the truck itself. A Suburban that has had wheel swaps, axle changes, or other heavy-duty modifications may still need a closer look at wheel width, clearance, and load needs before a tire is chosen, especially on a work-oriented vehicle that may have been altered over time.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1989 GMC Trucks V2500 Suburban?
Start with the basics: the tire should be the correct 235/85R16 size, radial construction, and compatible with the truck's 16-inch wheels. From there, compare the tire's intended use, sidewall styling, load specification, and approved rim-width range so the choice matches how the Suburban is driven and what wheels are actually on it.
A heavy-duty Suburban used for hauling, towing, or mixed road and gravel use may call for a different tire character than one kept mostly for occasional cruising. Appearance also matters on older trucks, so sidewall treatment can influence the final decision just as much as utility, provided the fitment details still line up.
What sidewall styles are available for 1989 GMC Trucks V2500 Suburban tires?
The available 235/85R16 option for this 1989 GMC Trucks V2500 Suburban uses RWL styling, which means raised white letters on the sidewall. That gives the truck a more traditional light-truck performance look than a plain blackwall and can change the overall presentation without changing the core tire size.
Sidewall style is mainly an appearance choice, but it matters on a square-body Suburban because the tire is visually prominent. Owners aiming for a more truck-oriented period look may like raised white letters, while those seeking a more restrained presentation may want to compare whether the wheel and vehicle style suit that treatment.
What brands offer tires for the 1989 GMC Trucks V2500 Suburban?
A BFGoodrich option is available in the 235/85R16 size for the 1989 GMC Trucks V2500 Suburban. The tire offered here is part of the All-Terrain T/A KO2 line, giving buyers a clearly defined truck-oriented radial choice within the correct fitment.
Brand is only one part of the decision. It still helps to compare the tire's sidewall style, load capacity, rim-width compatibility, and overall intended character against how the Suburban is used, especially since an older heavy-duty truck may serve very different roles from one owner to the next.
Restoration & Appearance
Which tire should I choose for a period-style 1989 GMC Trucks V2500 Suburban?
A period-style approach starts with keeping the correct 235/85R16 size on the 1989 GMC Trucks V2500 Suburban. Staying with the proper size preserves the truck's visual proportions and keeps the selection grounded in the fitment that belongs on this heavy-duty Suburban rather than drifting into a modernized size chosen only for appearance.
From there, the decision becomes one of presentation and intended use. A truck-oriented radial with raised white letters can suit the era well, but owners pursuing exact restoration standards should still compare surviving examples, factory literature, or marque-specific references before treating any sidewall style as the definitive historical choice.
How does tire construction affect the appearance of a restored 1989 GMC Trucks V2500 Suburban?
On this 1989 GMC Trucks V2500 Suburban, the primary fitment is already a radial, so the construction question is less about changing the visual profile from bias-ply to radial and more about selecting the right radial tire character. Size, tread personality, and sidewall treatment will have the biggest effect on how the truck looks.
A more aggressive all-terrain design can make the Suburban look more utility-focused, while the same size in a different sidewall treatment can shift the presentation toward a cleaner restoration-minded finish. Keeping the correct 235/85R16 proportions usually matters more visually than chasing a different size for a custom stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 GMC Trucks V2500 Suburban?
Yes. Even though the 1989 GMC Trucks V2500 Suburban uses a straightforward 235/85R16 fitment, changes such as aftermarket wheels, suspension lifts, lowering, axle swaps, or brake conversions can alter the space available for the tire and the wheel dimensions needed to support it properly.
An older Suburban often has a long service life, so it is smart to inspect what is actually on the truck before ordering replacements. Checking wheel diameter, wheel width, and clearance at the steering and fender areas helps confirm that the current setup still matches the intended 235/85R16 tire.
What should I inspect before driving a 1989 GMC Trucks V2500 Suburban on new tires?
Before road use, inspect the wheels for damage or excessive corrosion, confirm the tire pressure is set correctly for the application, and make sure the tires seat properly on the rims. It also helps to look over suspension and steering components, since worn parts can affect how a heavy Suburban tracks and wears its tires.
A short initial drive should be followed by another walk-around. Recheck air pressure, look for signs of rubbing, and watch for uneven stance or unusual steering feel. On a vehicle of this age, fresh tires can reveal problems that old, worn tires were masking, so early inspection is part of getting the truck safely back into use.
How should 235/85R16 tires on a collector 1989 GMC Trucks V2500 Suburban be maintained?
Collector-use tires still need regular attention even if the 1989 GMC Trucks V2500 Suburban is driven infrequently. Keep the 235/85R16 tires properly inflated, inspect for cracking, cuts, bulges, or unusual tread wear, and check for slow air loss before and after periods of storage.
Storage conditions matter just as much as mileage on an older truck. Keeping the Suburban away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition, while periodic movement of the vehicle reduces the chance of long-term flat spotting during extended parked periods.
