The 1989 Chevrolet Trucks R2500 Suburban comes from an era when heavy-duty full-size SUVs were expected to haul, tow, and cover long miles with equal ease. In Scottsdale and Silverado form, this three-quarter-ton Suburban was built around utility first, which makes proper tire fitment especially important for stance, load support, and road manners. The primary fitment is a 235/85R16 radial on a 16-inch rim, giving this truck a tall modern metric light-truck size rather than an older bias-ply format. Available choices in this size lean toward practical truck use, including raised white letter styling and an all-terrain series. The key decision is matching the correct size and wheel width to the truck's actual setup and intended use.
Which Tire Size Is Right for The 1989 Chevrolet Trucks R2500 Suburban
The 1989 Chevrolet Trucks R2500 Suburban uses one primary tire size: 235/85R16 radial on a 16-inch rim. That fitment stays consistent across the covered Scottsdale and Silverado sub-models, so the main decision is not between multiple primary sizes, but between tire style, load-oriented specifications, wheel-width compatibility, and how the truck is actually used.
235/85R16 is a metric radial size in which 235 represents the section width in millimeters, 85 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 1989 Chevrolet Trucks R2500 Suburban, that means a tall light-truck radial suited to the vehicle's heavy-duty character and 16-inch wheel fitment. Available product choice in this size includes BFGoodrich's All Terrain TA KO2 with raised white letter styling. This size is the right starting point when the Suburban still uses its correct 16-inch wheel setup and needs a proper heavy-duty radial fitment.

1989 Chevrolet Trucks R2500 Suburban Scottsdale
The 1989 Chevrolet Trucks R2500 Suburban Scottsdale uses the same 235/85R16 radial fitment as the other covered sub-model. Tire selection therefore centers on choosing the right radial option for wheel-width compatibility, intended road or mixed-use driving, and the appearance you want on the truck.
The 1989 Chevrolet Trucks R2500 Suburban Silverado also uses 235/85R16 radial tires. That keeps fitment simple, but it is still worth confirming that the truck has its correct 16-inch wheel setup before comparing sidewall styling, tire series, and other selection details.
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.

Common questions for the 1989 Chevrolet Trucks R2500 Suburban usually center on 235/85R16 fitment, 16-inch wheels, product selection, sidewall style, and the wheel, suspension, and tire-condition checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 1989 Chevrolet Trucks R2500 Suburban?
The 1989 Chevrolet Trucks R2500 Suburban uses a 235/85R16 radial tire. That size applies to the covered Scottsdale and Silverado sub-models, so the core fitment stays the same across both versions of this heavy-duty Suburban.
A correct size match is only the first step. It is also important to confirm that the truck still has 16-inch wheels and that the wheel width falls within the tire's usable range before choosing a replacement, especially on older trucks that may have seen wheel or suspension changes over time.
What size rim does a 1989 Chevrolet Trucks R2500 Suburban use?
The primary tire fitment for the 1989 Chevrolet Trucks R2500 Suburban uses a 16-inch rim. The available 235/85R16 product in this application is built for a wheel-width range of 6.0 to 7.5 inches, which helps frame the wheel compatibility side of the decision.
Rim diameter is critical because a 16-inch tire must be mounted on a 16-inch wheel. Width matters too, particularly on a three-quarter-ton Suburban where load support and tire shape are important, so measuring the actual wheel is worthwhile if the truck's history or current wheel setup is uncertain.
Do all 1989 Chevrolet Trucks R2500 Suburban sub-models use the same tire size?
Yes. The covered 1989 Chevrolet Trucks R2500 Suburban sub-models use the same 235/85R16 radial tire size. Both the Scottsdale and Silverado versions share that primary fitment, which simplifies replacement compared with vehicles that vary by trim or package.
Even with shared fitment, an older Suburban should still be checked individually. A previous owner may have changed wheels, ride height, or tire type, so verifying the actual wheel diameter, wheel width, and tire clearance on the truck itself helps avoid choosing a tire based only on what the model originally uses.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1989 Chevrolet Trucks R2500 Suburban?
Start with the correct size, 235/85R16, and confirm that the tire matches the truck's 16-inch wheel setup. On this Suburban, construction is already radial, so the next factors are wheel-width compatibility, load-oriented specifications, intended road use, and whether the truck needs a more highway-focused or more all-terrain style of tire.
Appearance can matter too, especially on a square-body Suburban where sidewall presentation changes the overall look. The available product in this fitment uses raised white letter styling and an all-terrain series, so the practical choice comes down to how closely that character matches the way the truck is driven and presented.
What sidewall styles are available for 1989 Chevrolet Trucks R2500 Suburban tires?
The available 235/85R16 product for the 1989 Chevrolet Trucks R2500 Suburban uses RWL sidewall styling, meaning raised white letters. That gives the truck a more traditional light-truck performance appearance than a plain blackwall sidewall would, while still staying within the correct primary size.
Sidewall style does not change the basic fitment, but it does affect the truck's finished look. Raised white letters often suit a late-1980s utility vehicle well, especially if the Suburban is presented with period-style wheels and trim, though the final choice should still begin with correct size, wheel match, and intended use.
What brands offer tires for the 1989 Chevrolet Trucks R2500 Suburban?
BFGoodrich is available in the 235/85R16 fitment for the 1989 Chevrolet Trucks R2500 Suburban. The offered product is part of the All Terrain TA KO2 series, giving this application a truck-focused radial option rather than a broad mix of vintage-style constructions or alternate sidewall treatments.
Brand alone should not decide the purchase. It still makes sense to compare the tire's rim-width range, load figure, sidewall style, and overall character against the Suburban's actual wheel setup and use, especially if the truck sees towing, carrying, or mixed pavement and unpaved driving rather than light occasional cruising.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Chevrolet Trucks R2500 Suburban?
A period-style approach for a 1989 Chevrolet Trucks R2500 Suburban begins with the correct 235/85R16 radial size on the proper 16-inch wheel. That preserves the truck's tall heavy-duty stance, which is a big part of how a three-quarter-ton Suburban from this era should look when viewed from the side or front.
From there, appearance comes down to tire character rather than changing fitment. Raised white letter styling can suit a late-1980s truck presentation well, but exact originality questions are best settled with vehicle-specific literature, surviving original examples, or marque references if the goal is a highly detailed restoration.
Does correct tire fitment matter for a 1989 Chevrolet Trucks R2500 Suburban restoration?
Yes, correct tire fitment matters because tire height, width, and construction have a strong effect on how a 1989 Chevrolet Trucks R2500 Suburban sits and how authentic the finished truck looks. Using the proper 235/85R16 radial size helps maintain the visual proportions expected of a heavy-duty square-body Suburban.
Fitment also affects practical details beyond appearance. A mismatched size can change wheel well fill, steering clearance, and the relationship between the tire and wheel, so restoration-minded buyers should confirm wheel diameter and width carefully before choosing a replacement, especially if the truck has worn aftermarket wheels at any point.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Chevrolet Trucks R2500 Suburban?
Yes. Modifications can change how a 235/85R16 tire works on a 1989 Chevrolet Trucks R2500 Suburban, even when that is the correct original fitment size. Aftermarket wheels, different wheel widths, altered offset, suspension lifts, lowering changes, or body modifications can all affect clearance and overall compatibility.
That is why the actual truck should be checked before replacing tires. A Suburban that still uses stock-style 16-inch wheels may be straightforward, but one with changed suspension or wheel hardware needs a closer look at steering clearance, fender space, and whether the wheel still falls within the tire's intended width range.
What should I inspect before driving a 1989 Chevrolet Trucks R2500 Suburban on new tires?
Before putting a 1989 Chevrolet Trucks R2500 Suburban back into regular use on new tires, inspect the wheels, lug hardware, valve stems, and overall tire seating on the rim. It also helps to check for suspension wear, steering looseness, and any signs that the previous tires were rubbing or wearing unevenly.
After installation, confirm inflation, watch for air loss, and make sure the tires clear through full steering travel. A heavier Suburban can quickly reveal weak shocks, tired springs, or alignment issues, so the first few drives should be treated as a shakedown period rather than assuming the new tires alone solve every road-use concern.
How should 235/85R16 tires on a collector 1989 Chevrolet Trucks R2500 Suburban be maintained?
Collector-use 235/85R16 tires on a 1989 Chevrolet Trucks R2500 Suburban should be kept properly inflated and inspected regularly for cracking, cuts, bulges, irregular wear, and slow air loss. Even a truck that sees limited mileage needs routine attention because age and storage conditions can affect tire condition as much as road miles do.
Storage habits matter on an older Suburban. Keeping the truck away from prolonged sun, moisture, and ozone sources helps preserve the tires, and occasional movement can help avoid long-term flat spotting. Before any longer drive, check pressure, tread condition, and the general condition of the wheels and suspension along with the tires.
