1986 Nissan Trucks D21 Tires

The 1986 Nissan Trucks D21 does not use one universal tire size across the full range. Depending on the exact sub-model, the primary radial sizes are 195/75R14, 215/75R14, 215/75R15, 235/75R15, and 31X10.50R15.

That means the first step is identifying the exact D21 configuration and confirming whether the truck has 14-inch or 15-inch wheels. A Base, E 4x2, or DRW setup does not follow the same fitment path as an SE 4x4, and modified wheels or tires can complicate matters further. Matching the truck to the correct primary size avoids choosing a tire that suits a different trim.

A 1986 Nissan Trucks D21 can use either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 195/75R14 and 215/75R14 fitments use 14-inch rims, while 215/75R15, 235/75R15, and 31X10.50R15 use 15-inch rims.

Wheel diameter should be confirmed before anything else, because a correct-looking tire in the wrong rim diameter is not a usable match. It also helps to confirm wheel width before narrowing product choices, especially on 15-inch truck applications where rim-width requirements can vary. If the truck has aftermarket wheels, inspect the actual wheel stamping or measure carefully rather than assuming the original setup remains in place.

The 1986 Nissan Trucks D21 covers several configurations, including 4x2, 4x4, DRW, Base, E, SE, and XE versions, and those do not all share the same wheel and tire package. That is why the truck family spans both 14-inch and 15-inch radial fitments.

The practical takeaway is that trim name alone is not always enough if the truck has been changed over the years. A wheel swap, suspension change, or different replacement tire strategy may leave the current truck wearing something other than its primary fitment. Verifying the exact sub-model and then comparing the actual wheel on the vehicle keeps the selection process grounded in what the truck can realistically use.

Start with the correct primary size for the exact 1986 Nissan Trucks D21 sub-model, then match the tire to the wheel diameter already on the truck. After that, the meaningful differences are sidewall style, tire series, brand, and whether the truck is better served by a classic-looking radial or a more truck-oriented all-terrain design.

Appearance matters, but wheel-width compatibility and intended use matter just as much. A compact 4x2 used for shows or light cruising may point toward a whitewall radial, while a 4x4 used more actively may call for a different presentation and tread character. It also helps to compare load figures and the truck’s actual setup before choosing among products in the same size.

Sidewall choices for the 1986 Nissan Trucks D21 vary by tire size, but the overall mix includes narrow whitewall, wide whitewall, RBL, and raised white letter styles. The whitewall choices appear across several 14-inch and 15-inch radial sizes, while the truck-focused BFGoodrich options bring the black sidewall or raised white letter look.

That gives the D21 owner room to shape the truck’s appearance without changing the primary fitment. A whitewall radial creates a more custom or restoration-oriented presentation, while RBL or raised white letters push the truck toward a more utility-minded 4x4 look. The right choice depends on the exact sub-model, the wheel on the truck, and how closely the finished look should reflect the period style you want.

Available tire brands for the 1986 Nissan Trucks D21 include Coker Classic, American Classic, BFGoodrich, Maxxis, Tornel, and Travelstar. Brand availability depends on the exact size, so a 195/75R14 truck will not have the same mix of choices as a 235/75R15 or 31X10.50R15 application.

Brand should be considered alongside the tire’s sidewall treatment, series, and wheel-fit details rather than by itself. Some sizes lean heavily toward classic whitewall radials, while others include more truck-oriented all-terrain offerings. Comparing the available products within the correct size is the best way to decide whether the priority is period-style appearance, a simple replacement radial, or a more assertive off-road visual character.

A period-style 1986 Nissan Trucks D21 tire choice starts with the truck’s correct primary size and wheel diameter, then narrows to the visual character you want. Many of the available radial options in 195/75R14, 215/75R14, 215/75R15, and 235/75R15 are offered with narrow whitewall or wide whitewall sidewalls that suit a traditional late-1980s custom or restoration-minded presentation.

The most convincing result usually comes from keeping the proper size for the sub-model and choosing a sidewall treatment that matches the truck’s intended style. Owners pursuing exact originality should still compare against period photos, brochures, or marque-specific references, because a size may be correct for the truck even when a given sidewall width or brand presentation reflects a later replacement preference.

On the 1986 Nissan Trucks D21, the primary fitments are radial, so the visual decision is less about bias-ply versus radial and more about sidewall treatment, tread character, and overall tire presence. A narrow or wide whitewall radial gives a very different look from an all-terrain radial with black sidewalls or raised white letters.

That distinction matters on a restored or carefully presented truck because the tires strongly influence whether it reads as stock-leaning, custom, or utility-focused. A 4x2 with whitewalls can take on a distinctly different personality than a 4x4 wearing all-terrain lettering, even when both are in correct primary sizes. Staying within the proper fitment preserves proportion while letting the truck’s final appearance be more deliberate.

Yes. Modifications can affect tire fitment on a 1986 Nissan Trucks D21 even when the chosen tire matches one of the primary sizes associated with the truck. Aftermarket wheels, suspension changes, ride-height changes, and body or fender alterations can all change the space available for a given tire.

That matters most on trucks using the larger 15-inch fitments such as 235/75R15 or 31X10.50R15, where wheel width and clearance become more important. A truck that originally used one size may also have been converted to a different wheel over time. Checking wheel diameter, wheel width, steering clearance, and fender clearance on the actual truck is the safest way to avoid surprises.

Before putting a 1986 Nissan Trucks D21 back on the road with new tires, inspect the wheels for the correct diameter and condition, verify lug hardware, and make sure the new tires are inflated appropriately for their rated load figures. It is also wise to look over the suspension, steering components, and brakes while the truck is already being serviced.

A fresh set of tires cannot compensate for worn front-end parts, damaged wheels, or clearance issues. The truck should be checked for rubbing at full steering lock, uneven ride height, and any signs that an older modification changed the fitment environment. A short test drive followed by another visual inspection helps confirm that the tires are seating, clearing, and tracking the way they should.

Tires on a collector 1986 Nissan Trucks D21 should be maintained with regular pressure checks, visual inspections, and occasional movement of the truck so one part of the tread does not sit loaded for long periods. Sidewalls should be checked for cracking, cuts, bulges, and any sign of slow air loss, especially on a truck that is driven only seasonally.

Storage conditions matter almost as much as mileage on an older compact pickup. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It also pays to inspect tread wear and the valve stems before any longer outing, because low-use collector vehicles often age their tires differently than regularly driven trucks.
