The 1986 Chevrolet Trucks C20 Suburban sits in the era when full-size Chevrolet utility vehicles were expected to haul people, cargo, and trailer duty with equal confidence. Its long-wheelbase, heavy-duty character makes tire choice more than a styling decision, especially for owners who still use these trucks on the road. This Suburban uses a 235/85R16 radial tire on a 16-inch rim, and that single primary fitment keeps the size question straightforward. The main choice is within the available radial tire itself, including an all-terrain series with raised white letter sidewalls. For a clean fitment outcome, match the tire to the truck's actual wheel setup and intended use.
Which Tire Size Is Right for The 1986 Chevrolet Trucks C20 Suburban
The 1986 Chevrolet Trucks C20 Suburban uses one primary tire size: 235/85R16. It is a radial fitment for a 16-inch rim, and that same size carries across the covered Custom, Scottsdale, and Silverado sub-model listings. Since the size itself is straightforward, the real decision becomes choosing the right tire type, sidewall presentation, and wheel-compatible product for how the truck will actually be driven.
A 235/85R16 size uses metric sizing, with 235 indicating nominal section width in millimeters, 85 identifying the aspect ratio, R showing radial construction, and 16 calling for a 16-inch rim. On the 1986 Chevrolet Trucks C20 Suburban, this radial format suits the truck's heavy-duty, road-going character and keeps fitment centered on one known size. Available product choice in this size includes BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. It is a practical fitment for owners who want to keep the truck in its intended size range while checking wheel width and overall vehicle setup carefully.

Tire Size & Fitment
What tire size fits a 1986 Chevrolet Trucks C20 Suburban?
The 1986 Chevrolet Trucks C20 Suburban uses a 235/85R16 radial tire. That is the primary size carried across the covered Custom, Scottsdale, and Silverado sub-model listings, including the front and rear position entries.
Because the size is consistent, the key next step is confirming that the truck still has the correct 16-inch wheels and an appropriate wheel width for the tire being considered. Older Suburbans are often modified over time, so checking the actual wheels on the vehicle matters just as much as knowing the original size.
What size rim does a 1986 Chevrolet Trucks C20 Suburban use?
The primary tire fitment for a 1986 Chevrolet Trucks C20 Suburban is built around a 16-inch rim. The available 235/85R16 product also calls for a rim width range of 6.0 to 7.5 inches.
Rim diameter is non-negotiable, since a 16-inch tire must be mounted on a 16-inch wheel. Rim width matters too, especially on a heavy-duty truck, because it affects how the tire seats and carries load. Measuring the wheels already on the Suburban is a smart step before selecting a replacement tire.
Do all 1986 Chevrolet Trucks C20 Suburban sub-models use the same tire size?
Yes. The covered 1986 Chevrolet Trucks C20 Suburban Custom, Scottsdale, and Silverado sub-models all use the same 235/85R16 radial tire size. The front and rear position entries are also shown with that same size.
That consistency makes tire shopping easier, because the question is not which size belongs to which trim. The practical check is whether the truck still retains wheels and suspension dimensions that suit 235/85R16. Trucks that have seen wheel swaps, lift changes, or other alterations should always be measured before a new tire is chosen.
Choosing the Right Tire
What should I consider when choosing a 235/85R16 tire for a 1986 Chevrolet Trucks C20 Suburban?
Start with the essentials: correct size, radial construction, and compatibility with a 16-inch wheel. For this Suburban, the available 235/85R16 option also includes a 6.0 to 7.5 inch rim-width range, a 3,042-pound maximum load capacity at 80 psi, and an all-terrain design.
After that, think about how the truck is actually used. A Suburban that sees road trips, light hauling, or mixed pavement and gravel use may suit an all-terrain tire differently than one kept mostly for occasional cruising. Matching the tire's specifications to the wheel dimensions and the truck's real-world duty is the most useful comparison.
What sidewall styles are available for 1986 Chevrolet Trucks C20 Suburban tires?
The available 235/85R16 product for the 1986 Chevrolet Trucks C20 Suburban uses an RWL sidewall, meaning raised white letters. That gives the truck a more assertive, late-classic light-truck look than a plain blackwall presentation.
Sidewall styling does not change the required size, but it does affect the truck's visual character. Raised white letters tend to suit a more period-flavored utility or off-road appearance, especially on square-body era Chevrolet trucks. The right choice depends on whether the goal is a cleaner stock-looking presentation or a bolder all-terrain style.
What tire series are available for the 1986 Chevrolet Trucks C20 Suburban?
The available tire series in the primary 235/85R16 fitment is BFGoodrich's All Terrain TA KO2. It is a radial all-terrain series sized for a 16-inch wheel and paired here with raised white letter sidewalls.
Series choice helps define the truck's character more than the size question does, since the Suburban already points to one main fitment. An all-terrain series can make sense for a vehicle that still sees utility use or mixed-surface driving. Even so, wheel width, load needs, and overall vehicle setup should still be confirmed before installation.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Chevrolet Trucks C20 Suburban?
A period-style approach starts by staying with the correct 235/85R16 size and 16-inch rim fitment used on the 1986 Chevrolet Trucks C20 Suburban. Within that framework, a radial tire with an all-terrain presentation can suit the truck's heavy-duty utility character without drifting away from its era.
Appearance goals matter here just as much as fitment. Some owners want a more restrained truck look, while others prefer a more rugged presentation that still feels at home on a mid-1980s Chevrolet. If exact restoration detail is important, compare the tire's overall look with trusted period photos, dealer literature, or marque-specific references before making the final choice.
How does tire construction affect the appearance of a restored 1986 Chevrolet Trucks C20 Suburban?
The 1986 Chevrolet Trucks C20 Suburban uses a radial tire in its primary 235/85R16 fitment, so radial construction is already part of the vehicle's period character. On a restored truck, the visual difference comes less from bias-ply versus radial and more from tread style and sidewall treatment.
That means the truck's finished look can change noticeably even when the size remains correct. A raised white letter sidewall creates a more assertive 1980s light-truck appearance, while a simpler sidewall would read more understated. Keeping the proper overall fitment and a wheel-compatible tire usually does more for authenticity than chasing a dramatic style change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Chevrolet Trucks C20 Suburban?
Yes. A 1986 Chevrolet Trucks C20 Suburban may use 235/85R16 as its primary size, but aftermarket wheels, suspension changes, ride-height adjustments, and body modifications can all affect whether that size still works properly on the truck in front of you.
Older full-size trucks are often changed over the years, so it is worth checking wheel diameter, wheel width, and clearance at the fenders and steering components before mounting replacement tires. Even when the nominal size stays the same, a different wheel setup can change how comfortably that tire works on the vehicle.
What should I inspect before driving a 1986 Chevrolet Trucks C20 Suburban on new tires?
Before putting a 1986 Chevrolet Trucks C20 Suburban back into regular road use on new tires, inspect the wheels for the correct 16-inch diameter and suitable width, then check valve stems, lug hardware, alignment condition, and visible clearance around the suspension and body.
It also helps to look over the rest of the truck with a road-use mindset. Make sure the tires are inflated appropriately for the application, then watch for rubbing, vibration, or uneven wear during the first miles. A Suburban that has been sitting for long periods deserves an especially careful inspection before any longer drive.
How should 235/85R16 tires on a collector 1986 Chevrolet Trucks C20 Suburban be maintained?
235/85R16 tires on a collector-era 1986 Chevrolet Trucks C20 Suburban should be inspected regularly for air loss, uneven wear, sidewall cracking, cuts, and bulges. Pressure should be checked consistently, especially on a vehicle that spends long periods parked between drives.
Storage conditions matter almost as much as mileage on an older truck. Keeping the Suburban away from prolonged sunlight, excess moisture, and ozone sources can help preserve the tires over time. It is also wise to inspect the tires before every significant outing, since low-use collector vehicles can age their tires even when tread wear looks minimal.
