1986 Chevrolet Trucks C20 Tires

The 1986 Chevrolet Trucks C20 uses either 215/85R16 or 235/85R16 radial tires. The correct size depends on the truck’s exact sub-model and GVWR, with 6400- and 7200-GVWR versions using 215/85R16 and 8600-GVWR versions using 235/85R16.

That means trim name alone is not enough to choose a tire. Before selecting one, confirm the truck’s GVWR and check that the wheels on the truck are still the correct 16-inch setup, especially if it has had replacement wheels, suspension work, or a long service life with mixed parts.

Both primary tire sizes used on the 1986 Chevrolet Trucks C20 fit a 16-inch rim. Whether the truck uses 215/85R16 or 235/85R16, the wheel diameter stays the same, which simplifies the basic fitment question compared with trucks that used multiple rim diameters.

The important follow-up is that the right diameter does not automatically mean every wheel is suitable for every tire. Actual wheel width still matters, and that becomes especially important when moving into 235/85R16 fitment, so the wheel should be measured and checked before choosing a replacement tire.

The 1986 Chevrolet Trucks C20 has more than one tire size because fitment changes with GVWR. Trucks rated at 6400 or 7200 GVWR use 215/85R16, while 8600-GVWR versions use 235/85R16, even across Custom, Scottsdale, and Silverado trim levels.

That makes the truck’s weight-rating configuration more important than the badge on the fender when buying tires. A C20 that has changed hands several times may also have wheels swapped from another truck, so it is smart to verify the current wheel setup and the truck’s exact rating before ordering.

Start with the correct size for the truck’s GVWR, since the 1986 Chevrolet Trucks C20 uses either 215/85R16 or 235/85R16. After that, compare construction, wheel compatibility, load-oriented specifications, and whether the tire’s appearance and intended use suit a working truck, a driver, or a preserved square-body pickup.

A tire that matches the size code still needs to make sense for the actual wheel and the way the truck is used. Looking at rim-width range, sidewall style, and series design helps narrow the choice without assuming that every tire in the same nominal size will feel or present the same.

Raised white letter sidewall styling is available in 235/85R16 for the 1986 Chevrolet Trucks C20. That sidewall treatment appears on the BFGoodrich All Terrain TA KO2 and gives the truck a distinctly traditional light-truck look compared with a plain black sidewall presentation.

Sidewall style does not change the underlying need to match the correct size and wheel setup. It does, however, influence how the truck presents visually, so owners restoring a clean square-body or building a period-flavored driver may want to weigh appearance just as carefully as tread pattern and fitment.

BFGoodrich is available in 235/85R16 for the 1986 Chevrolet Trucks C20. The current product choice in that size includes the All Terrain TA KO2 radial, which combines a truck-oriented series design with raised white letter sidewalls.

Brand matters most after the correct size and wheel compatibility are settled. On a C20, that means confirming whether the truck belongs in 215/85R16 or 235/85R16 first, then comparing the available brand’s series character, appearance, and wheel-width requirements against the way the truck will actually be driven.

A period-style choice for a 1986 Chevrolet Trucks C20 starts with keeping the correct radial size for the truck’s GVWR. On these trucks, that means 215/85R16 for 6400- and 7200-GVWR versions or 235/85R16 for 8600-GVWR versions, rather than choosing by appearance alone.

Once the fitment is right, appearance can help refine the decision. A more traditional truck presentation may point toward a tire and sidewall style that looks appropriate for a mid-1980s pickup, but exact originality should be checked against truck-specific literature or marque references when that level of detail matters.

The 1986 Chevrolet Trucks C20 uses radial tire fitment, so the visual question is less about bias-ply versus radial conversion and more about choosing the right radial presentation. Size, tread character, and sidewall treatment will do more to shape the truck’s look than construction type alone on this application.

That is especially true on a square-body truck, where tires contribute heavily to stance and overall personality. A raised white letter sidewall can give a more period-flavored truck look, while a different presentation may feel more restrained, so appearance should be balanced with proper size, wheel compatibility, and intended use.

Yes, modifications can affect tire fitment on a 1986 Chevrolet Trucks C20 even when the truck still uses the correct nominal tire size. Aftermarket wheels, changes in wheel width, altered ride height, suspension repairs, or body modifications can all change how a 215/85R16 or 235/85R16 tire sits on the truck.

That is why a replacement should be matched to the truck as it exists today, not only to its original configuration. Checking wheel dimensions, steering clearance, rear clearance, and overall tire-to-body space helps prevent surprises, particularly on older trucks that may have had decades of repairs or customization.

Before driving a 1986 Chevrolet Trucks C20 on new tires, inspect the wheels for damage or corrosion, verify correct inflation, and make sure the tires are mounted in the proper size for the truck’s GVWR. It is also wise to look over lug hardware, valve stems, and overall tread and sidewall condition.

A short road test should include attention to steering feel, vibration, and any sign of rubbing at full lock or over bumps. Older trucks often carry suspension wear that was masked by the previous tires, so checking alignment condition and basic front-end health is just as important as the new tires themselves.

Tires on a collector 1986 Chevrolet Trucks C20 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and driven often enough to avoid long periods of neglect. Even a truck that sees only occasional use still needs routine checks because age and storage conditions affect tire condition over time.

Storage matters nearly as much as mileage on an older pickup. Keeping the truck away from prolonged heat, direct sunlight, moisture, and ozone sources can help preserve the tires, and a visual inspection before each outing is smart practice for a C20 that spends much of its life parked between drives.
