1987 Chevrolet Trucks R20 Tires

A 1987 Chevrolet Trucks R20 uses either 215/85R16 or 235/85R16 radial tires, depending on the truck's GVWR-based configuration. The 6400- and 7200-GVWR versions use 215/85R16, while the 8600-GVWR versions use 235/85R16. Both sizes are built for 16-inch wheels.

The main step is identifying the exact R20 sub-model before choosing a tire. Trim name alone is not enough, because Custom Deluxe, Scottsdale, and Silverado each appear with different GVWR ratings. If the truck has had wheel, axle, or suspension changes over the years, verify the current wheel size and the clearance around the tire before replacing anything.

The 1987 Chevrolet Trucks R20 uses 16-inch rims with both of its primary tire sizes. Whether the truck is fitted with 215/85R16 or 235/85R16, the wheel diameter remains the same at 16 inches, so the fitment difference is tied to tire size and truck rating rather than a different rim diameter.

Wheel diameter is only part of the fitment picture on an older truck. Width also matters, especially when moving into the larger 235/85R16 size, because tire and wheel compatibility affects how the tire seats and carries load. It is worth checking the actual wheels on the truck rather than assuming they are still the original type or width.

The 1987 Chevrolet Trucks R20 has more than one tire size because the truck was offered in several GVWR-based configurations. Lighter-rated 6400 and 7200 versions use 215/85R16, while heavier 8600-GVWR versions use 235/85R16. The difference reflects the truck's intended load-carrying setup rather than a simple trim-level styling change.

That means the correct tire is tied to how the truck was configured, not just what badge is on the fender. A Silverado can use the same size as a Custom Deluxe if the GVWR is the same. Checking the truck's rating, its wheels, and any past modifications helps keep replacement tires aligned with the setup actually under the vehicle today.

Start with the correct GVWR-based size, because the 1987 Chevrolet Trucks R20 uses 215/85R16 on 6400- and 7200-GVWR versions and 235/85R16 on 8600-GVWR versions. Both are 16-inch radial fitments, so the first question is which size belongs on the specific truck rather than whether it needs a different construction type.

After size is confirmed, compare details that affect how the truck will be used, including wheel compatibility, tire load specification, sidewall style, and tread character. A truck kept mostly stock may call for a straightforward replacement approach, while a truck used for hauling, back-road travel, or a more aggressive visual stance may justify a closer look at the available product design.

Among the currently available product options for the 1987 Chevrolet Trucks R20, the visible sidewall treatment shown in 235/85R16 is RWL, or raised white letter. That sidewall style gives the truck a more assertive late-classic pickup appearance than a plain black sidewall and fits well with period-inspired all-terrain presentation.

Sidewall style is an appearance decision as much as a fitment decision, so it should come after confirming the proper tire size and wheel setup. Raised white letters may suit a more rugged or recreational look, while some owners may prefer a simpler presentation. The right choice depends on whether the truck is being restored, preserved, or used regularly with a more utility-focused theme.

BFGoodrich is represented among the available tire choices for the 1987 Chevrolet Trucks R20, specifically in the 235/85R16 size. The product shown is from the All-Terrain T/A KO2 line, which places the emphasis on a more truck-oriented tread style rather than a smooth passenger-car presentation.

Brand matters most after the basic fitment is settled. On an R20, that means verifying whether the truck belongs to the 215/85R16 or 235/85R16 group first, then comparing the available tire's wheel-width compatibility, sidewall style, and intended use. A heavier-rated working truck may prioritize different characteristics than a restored pickup that sees mostly light weekend driving.

A period-style 1987 Chevrolet Trucks R20 starts with using the correct primary tire size for the truck's GVWR-based configuration. That means 215/85R16 on 6400- and 7200-GVWR versions or 235/85R16 on 8600-GVWR versions, both in radial construction and on 16-inch rims, preserving the truck's intended overall tire format.

From there, the choice depends on how closely the truck is being restored versus how it will actually be driven. A stock-appearing truck benefits from staying close to the original size and proportions, while a truck with more utility or trail-oriented styling may lean toward a more aggressive tread presentation. Exact originality questions are best settled with truck-specific historical references and build documentation.

On a restored 1987 Chevrolet Trucks R20, tire construction is less of a visual dividing line than it would be on an earlier classic, because the truck's primary fitments are already radial. The more noticeable appearance factors are the correct size, the tire's overall proportions on a 16-inch wheel, and details like sidewall treatment.

That makes size discipline especially important during restoration. A truck wearing the proper 215/85R16 or 235/85R16 fitment will usually look more settled and appropriate than one wearing a substitute chosen only for convenience. Sidewall styling can further shape the final look, especially if the goal is to reflect an authentic late-1980s truck character rather than a modernized build.

Yes, modifications can affect tire fitment on a 1987 Chevrolet Trucks R20 even when the truck is using one of its correct 16-inch tire sizes. Aftermarket wheels, changes in wheel width, altered offset, suspension lifts or drops, and brake or axle swaps can all influence how a 215/85R16 or 235/85R16 tire sits and clears.

That is especially important on older pickups that may have passed through several owners. A tire that matches the truck's original-style GVWR fitment still needs to be checked against the actual wheel and suspension setup now on the vehicle. Looking at front steering clearance, rear fender space, and overall axle-to-body relationship helps prevent surprises after installation.

Before driving a 1987 Chevrolet Trucks R20 on new tires, inspect the wheels for damage or excessive corrosion, confirm that all tires match the intended size for the truck's configuration, and check that inflation is appropriate for the tire and the truck's use. Lug hardware, valve stems, and general wheel condition also deserve attention.

A short check for clearance is wise before normal road use. Turn the steering from lock to lock, look for any contact near the front fenders or suspension, and confirm that the rear tires sit properly under load. On an older truck, it also helps to review alignment, suspension wear, and brake condition so new tires are not being asked to compensate for unrelated problems.

Before a longer drive in a 1987 Chevrolet Trucks R20, make sure the tires are the correct GVWR-based size, inspect tread and sidewalls for cuts or bulges, and check for any signs of air loss. Wheel condition, inflation, and even wear matter on a truck that may still see work duty or carry extra load on the road.

Longer trips put more emphasis on overall vehicle condition, not just the tires themselves. It is smart to look over the suspension, steering components, and alignment if the truck wanders or feels unsettled. A spare in usable condition is also worth checking, especially on a vintage pickup where roadside convenience can depend on having the right wheel and tire combination ready.
