1987 GMC Trucks R1500 Suburban Tires

The primary tire size for the 1987 GMC Trucks R1500 Suburban is 235/75R15. This is a radial tire size built for a 15-inch rim, and it applies across the covered 4x2, 4x2 (Diesel), and 4x2 (Gas) sub-models on this page.

That means the fitment question is less about choosing between multiple factory sizes and more about confirming that the truck still has the expected wheel setup. If the Suburban has aftermarket wheels, suspension changes, or a different wheel width than stock-type applications, check rim dimensions and clearance before choosing among the available 235/75R15 options.

The 1987 GMC Trucks R1500 Suburban uses a 15-inch rim with its 235/75R15 tire fitment. The tire size itself confirms that wheel diameter, since the final number in 235/75R15 refers to a 15-inch rim.

Wheel diameter is only part of the picture, though. Individual 235/75R15 products can call for different rim-width ranges, so it is worth measuring the wheel before settling on a specific tire. That is especially important on older trucks that may have replacement wheels, custom steel wheels, or later-model takeoffs that still share the same diameter.

Yes. The covered 1987 GMC Trucks R1500 Suburban sub-models on this page all use the same 235/75R15 radial tire size. That includes the 4x2, 4x2 (Diesel), and 4x2 (Gas) versions.

Shared sizing makes replacement easier because the main decision shifts to tire style and specification rather than sub-model-specific dimensions. Even so, an older Suburban may no longer wear its original wheel set, so it is smart to confirm the actual wheel diameter and width on the truck before choosing between whitewall, raised white letter, or other 235/75R15 product variations.

Start with the correct size and construction: 235/75R15 radial on a 15-inch rim. After that, compare the available tire by intended use, sidewall appearance, rim-width specification, and product details such as load capacity and weight where those differences matter to how the Suburban is driven and presented.

A truck kept for cruising or restoration-style presentation may lean toward narrow or wide whitewalls, while a more utility-minded Suburban may suit an RWL design better. It also helps to confirm whether the vehicle spends most of its time on local roads, highway trips, or occasional hauling, since that practical use often narrows the most appropriate product choice within the same size.

235/75R15 tires for the 1987 GMC Trucks R1500 Suburban are available in several sidewall styles, including RWL, narrow whitewall, and wide whitewall. That gives the truck a broad range of visual directions while keeping the same primary size and radial construction.

Sidewall choice changes the Suburban's character more than many owners expect. RWL tends to give a more truck-oriented, later-period look, while narrow and wide whitewalls create a more traditional presentation. Appearance still needs to be balanced with fitment details, so it is worth checking the wheel width and reviewing the individual tire's specifications before choosing a sidewall solely on style.

Available 235/75R15 tires for the 1987 GMC Trucks R1500 Suburban include options from BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Those products also span different tire series, including All Terrain TA KO2, Silvertown Radial, Star Series, Coker Classic Radial, Tornel Classic, Classic Whitewall MA-1, American Classic Radial, and UN106.

Brand choice works best when paired with the kind of Suburban you are building or maintaining. Some options emphasize traditional whitewall styling, while others lean toward a more utility-focused look. Instead of choosing by name alone, compare the sidewall treatment, rim-width requirement, and load specification so the tire suits both the truck's appearance and its actual road use.

A period-style 1987 GMC Trucks R1500 Suburban still starts with the correct primary size, 235/75R15. From there, the most appearance-sensitive choices are usually among the whitewall radials, with narrow and wide whitewall versions offering different visual weight while keeping the same basic fitment and modern radial construction.

The right look depends on how the truck is being restored or preserved. A cleaner, more upscale presentation may point one way, while a more utilitarian Suburban may look more natural with a simpler sidewall treatment. If exact originality matters, compare the tire choice against period photos, build documentation, and marque-specific restoration references before deciding on a stripe width or style.

On the 1987 GMC Trucks R1500 Suburban, construction is straightforward because the primary fitment is already radial. That means the visual difference in a restoration-oriented setup is shaped less by bias-ply versus radial concerns and more by sidewall presentation, brand styling, and the overall profile of the selected 235/75R15 tire.

For many owners, the biggest appearance decision is whether the truck should wear a traditional whitewall or a more work-ready raised white letter sidewall. Keeping the correct size helps preserve the Suburban's stance, but the wheel itself also matters. An incorrect wheel width or altered offset can change how even the right-size tire looks once mounted on the truck.

Yes. Even though 235/75R15 is the primary tire size for the 1987 GMC Trucks R1500 Suburban, modifications can change how well that size works in practice. Aftermarket wheels, altered wheel width, suspension lifts or drops, and body or steering changes can all affect clearance and overall fitment.

A Suburban that still carries stock-type wheels is usually the simplest case, but older trucks are often changed over time. Measure the actual wheel diameter and width, then check clearance at full steering lock and through suspension movement. That small inspection can prevent rubbing, sidewall interference, or mounting a tire that does not suit the truck's current setup.

Before road use, inspect the wheels for damage or corrosion, confirm the tire size matches the intended wheel diameter, and verify that the new tires are mounted and inflated properly. It also helps to look over the suspension and steering components on an older Suburban so the new tires are not working against worn hardware.

A careful walkaround after installation is worthwhile. Check for fender or frame clearance, especially at full lock, and watch for any uneven stance that could suggest unrelated chassis issues. On a vehicle that has spent long periods parked, rechecking air pressure and fastener tightness after the first few drives is a smart habit before longer highway use.

235/75R15 tires on a collector-era 1987 GMC Trucks R1500 Suburban should be kept at the proper inflation for the specific tire, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of sun, moisture, and ozone exposure. Low-mileage use does not eliminate the need for routine inspection.

Collector trucks often age their tires through time and storage more than through tread wear. Rolling the vehicle periodically, keeping it on a clean dry surface, and checking for slow air loss can help preserve the tires between outings. It is also wise to inspect the spare and to look over the wheel itself, since tire condition and wheel condition work together.
