The 1989 GMC Trucks V1500 Suburban came from the last years of GMC’s square-body truck era, a time when full-size utility vehicles were expected to handle family hauling, towing, and everyday road use with equal confidence. On a Suburban like this, tire choice affects not just stance, but how the truck looks and feels in service. The primary fitment is a 235/75R15 radial on a 15-inch rim, and that same size carries across the covered passenger, gas, diesel, and aluminum-wheel variations. Available choices range from raised white letter all-terrain styling to narrow and wide whitewall radials, making it important to match the tire to the truck’s intended appearance, wheel setup, and road use.
Which Tire Size Is Right for The 1989 GMC Trucks V1500 Suburban
The 1989 GMC Trucks V1500 Suburban uses one primary tire size: 235/75R15, a radial tire for a 15-inch rim. That fitment stays consistent across the covered passenger-capacity, gas, diesel, and aluminum-wheel sub-models, so the main decision is not which size fits, but which tire style, brand, series, and sidewall treatment best suits the way the Suburban is used and presented.
235/75R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1989 GMC Trucks V1500 Suburban, this radial fitment supports the truck’s later-model full-size character and keeps selection focused on product style rather than alternate primary sizes. Available choices include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar, with sidewall options ranging from raised white letter to narrow and wide whitewall designs. It is the size to evaluate when keeping the truck on its proper 15-inch wheel setup and tailoring the look toward utility, classic truck, or restoration-oriented use.
Tire fitment is straightforward across the covered 1989 GMC Trucks V1500 Suburban sub-models because each one uses the same 235/75R15 radial size. Checking the exact sub-model still matters because passenger configuration, fuel type, and wheel material can influence how an owner approaches appearance, restoration goals, and wheel verification.
This diesel passenger-configuration Suburban uses the same 235/75R15 radial fitment as the rest of the covered lineup. Tire choice is mainly about selecting the right sidewall style and series for the truck’s intended presentation while keeping the 15-inch wheel setup in mind.
This aluminum-wheel diesel sub-model also uses 235/75R15 radial tires. Since the size remains unchanged, the practical next step is confirming wheel width and then choosing between utility-oriented styling such as raised white letters or more restoration-minded whitewall options.
This gas-powered passenger version stays with the standard 235/75R15 radial size. That makes product selection the real focus, whether the goal is a traditional full-size truck look, a cleaner whitewall presentation, or a more rugged tire style.
This gas sub-model with aluminum wheels uses the same 235/75R15 radial fitment. Tire selection comes down to matching the tire’s sidewall treatment and series character to the wheel appearance and checking that the wheel width stays within the tire’s intended range.
This higher-capacity diesel Suburban keeps the same 235/75R15 radial size. With no change in primary fitment, the buyer can concentrate on choosing a tire that matches the truck’s look and verifying that wheel condition and overall tire condition are ready for road use.
This 8- and 9-passenger gas version also uses 235/75R15 radial tires. The selection process is therefore centered on brand, series, and sidewall style rather than alternate fitment, along with a quick check that the truck still has its correct 15-inch wheel setup.
This diesel aluminum-wheel passenger Suburban continues with the same 235/75R15 radial size. That keeps fitment simple and shifts attention to wheel-width compatibility, appearance goals, and whether a traditional whitewall or more truck-oriented sidewall suits the vehicle better.
This gas aluminum-wheel version uses the same 235/75R15 radial fitment as the other covered sub-models. The choice is less about size and more about selecting the tire series and sidewall style that complements the truck while staying appropriate for the installed wheel.
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 GMC Trucks V1500 Suburban usually center on the 235/75R15 fitment, 15-inch wheel compatibility, sidewall and brand choices, and what to inspect before putting a full-size collector truck back on the road.
Tire Size & Fitment
What tire size fits a 1989 GMC Trucks V1500 Suburban?
The 1989 GMC Trucks V1500 Suburban uses a 235/75R15 radial tire. That size applies across the covered gas and diesel versions, passenger-capacity variations, and aluminum-wheel sub-models, so there is one primary fitment to work from on this page.
That makes the next decision more about tire style than tire size. Once the truck is confirmed to still have its 15-inch wheels, the main variables become sidewall treatment, brand, tire series, rim-width compatibility, and whether the Suburban is being set up for utility driving or a more restoration-oriented appearance.
What size rim does a 1989 GMC Trucks V1500 Suburban use?
The primary tire fitment for the 1989 GMC Trucks V1500 Suburban is built around a 15-inch rim. The 235/75R15 size itself confirms that wheel diameter, and the available products for this fitment are also designed for 15-inch applications.
Wheel diameter is only part of the check, especially on an older truck. It is also smart to confirm the actual wheel width, since available 235/75R15 products can vary in recommended rim-width range, and many surviving Suburbans have seen wheel changes over the years.
Do all 1989 GMC Trucks V1500 Suburban sub-models use the same tire size?
Yes. The covered 1989 GMC Trucks V1500 Suburban sub-models all use the same 235/75R15 radial tire size, including gas and diesel versions, 2- through 9-passenger configurations, and versions with aluminum wheels.
That consistency simplifies fitment, but it does not eliminate the need to inspect the truck itself. A Suburban that has been modified with different wheels, suspension changes, or replacement axles should still be checked carefully before choosing a tire based only on the original-style fitment.
Choosing the Right Tire
What should I consider when choosing a 235/75R15 tire for a 1989 GMC Trucks V1500 Suburban?
Start with the correct size and construction, which for this Suburban is a 235/75R15 radial on a 15-inch wheel. From there, compare the tire’s intended look, sidewall style, brand, tire series, and rim-width suitability to the actual wheels on the truck.
A raised white letter all-terrain design creates a different presentation than a narrow or wide whitewall radial, even though the size is the same. It also helps to compare load figures at their stated pressures and consider whether the truck is used as a driver, a cruiser, or a restoration-minded classic.
What sidewall styles are available for 1989 GMC Trucks V1500 Suburban tires?
Available 235/75R15 tires for the 1989 GMC Trucks V1500 Suburban include raised white letter, narrow whitewall, and wide whitewall styles. That gives the truck owner a broad appearance range, from a more rugged period truck look to a cleaner classic full-size SUV presentation.
Sidewall style can change the character of the Suburban as much as the wheel itself. Raised white letters suit utility-oriented builds, while narrow and wide whitewalls can better support a restoration-oriented or custom look, so the choice should match both the truck’s finish and its intended use.
What brands offer tires for the 1989 GMC Trucks V1500 Suburban?
235/75R15 tires for the 1989 GMC Trucks V1500 Suburban are available from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Those brands appear across several series, including all-terrain and classic-style whitewall radial offerings.
Brand alone should not be the only deciding factor. It is worth comparing sidewall treatment, tire series character, rim-width range, and load capacity at the stated pressure so the selected tire matches the Suburban’s wheels, appearance goals, and the way the truck will actually be driven.
Restoration & Appearance
Which tire should I choose for a period-style 1989 GMC Trucks V1500 Suburban?
For a period-style 1989 GMC Trucks V1500 Suburban, the right choice depends on the appearance you want to preserve. Since the truck uses a 235/75R15 radial, the most relevant period-style decisions are usually sidewall treatment and overall visual character rather than changing to another primary size.
A wide whitewall, narrow whitewall, or raised white letter design can each push the truck in a different visual direction. When exact originality matters, it is wise to compare the truck against model-specific historical references, period photos, or marque-club guidance before settling on one sidewall style.
How does tire construction affect the appearance of a restored 1989 GMC Trucks V1500 Suburban?
On the 1989 GMC Trucks V1500 Suburban, the primary fitment is already radial, so construction change is less of an appearance issue than it is on an earlier bias-ply-era vehicle. The bigger visual difference usually comes from sidewall treatment, tread character, and the proportions of the tire on the 15-inch wheel.
That means a restoration-minded owner can stay within the correct size and still shape the truck’s look substantially. A utility-style all-terrain radial creates a more work-ready impression, while narrow and wide whitewall radials deliver a more polished classic full-size truck presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 GMC Trucks V1500 Suburban?
Yes. Even though the original-style fitment is 235/75R15 on a 15-inch wheel, modifications can change how that size sits on the truck. Aftermarket wheels, different wheel widths, suspension lifts or drops, and body changes can all affect clearance and overall fitment behavior.
That is why an older Suburban should be inspected as it sits today, not only as it left the factory. A quick check of wheel diameter, wheel width, steering clearance, fender clearance, and suspension condition can prevent problems before a new tire is mounted.
What should I inspect before driving a 1989 GMC Trucks V1500 Suburban on new tires?
Before road use, inspect the wheels, valve stems, lug hardware, and overall condition of the suspension and steering components. On the tires themselves, confirm proper inflation, look for any mounting damage, and make sure there is adequate clearance at full steering lock and through normal suspension travel.
A full-size Suburban can hide age-related issues if it has sat for long periods. It is also smart to check for uneven wear patterns from prior alignment problems, verify there is no rubbing under load, and recheck pressure after the first few drives once the tires have settled in.
How should 235/75R15 tires on a collector 1989 GMC Trucks V1500 Suburban be maintained?
Collector-use 235/75R15 tires should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Even when tread wear is low, older trucks often spend long periods parked, which makes sidewall cracking, flat spotting, and slow air loss more important than mileage alone.
Keeping the Suburban out of prolonged sunlight, excess heat, and ozone sources helps protect the rubber over time. It also helps to move the vehicle periodically, inspect for cuts or bulges before each season of use, and have any questionable tire or wheel condition checked before longer trips.
