1982 Nissan Trucks 720 Tires

A 1982 Nissan Trucks 720 can use GR78-15, G78-15, E78-14, 185R14, 700-14, or 195R14, depending on the exact sub-model. That range includes both 14-inch and 15-inch wheel fitments, and it also spans both bias-ply and radial construction.

The key step is matching the tire to the exact truck configuration rather than the model name alone. A 4x4 King Cab, 4x4 regular-bed truck, H.D., King Cab, Long Bed, Reg. Bed, and Sport do not all share the same size, so wheel diameter and sub-model description should be confirmed before comparing brands, sidewall styles, or radial alternatives.

The 1982 Nissan Trucks 720 uses either a 14-inch or 15-inch rim, depending on the sub-model and tire size. GR78-15 and G78-15 are 15-inch fitments, while E78-14, 185R14, 700-14, and 195R14 are 14-inch fitments.

That makes rim diameter one of the first things to verify on the truck before choosing tires. Even within the same model year, different 720 versions were built around different wheel diameters, and a previous owner may have changed wheels over time, so the actual wheel on the truck should match the intended tire size before moving on to style or construction decisions.

The 1982 Nissan Trucks 720 used multiple tire sizes because the lineup covered several distinct sub-models, including 4x4, King Cab, H.D., Long Bed, Reg. Bed, and Sport versions. Those trucks were not all equipped the same way, so tire fitment varies by configuration, wheel diameter, and construction type.

In practice, that means tire selection starts with identifying the exact truck rather than choosing by year and make alone. A 15-inch 4x4 fitment should not be treated like a 14-inch two-wheel-drive fitment, and a bias-ply size should not be confused with a radial size simply because the numbers appear close at first glance.

G78-15 is a bias-ply tire size on the 1982 Nissan Trucks 720. It is used on certain 4x4 regular-bed versions, while GR78-15 is the separate radial fitment in the same general 15-inch family for other 4x4 configurations.

That distinction matters because G78-15 and GR78-15 are not just two ways of writing the same tire. Owners considering replacement tires should confirm whether the truck is supposed to stay with a traditional bias-ply setup or whether a radial-equivalent path makes more sense for current use, while still checking wheel width, clearance, and overall vehicle setup.

Radial equivalents for G78-15 include 205R15, P215/75R15, P225/70R15, and 710R15. In that group, 205R15 is the 80-series metric radial equivalent, P215/75R15 is the 75-series P-metric option, P225/70R15 is the 70-series P-metric option, and 710R15 is the bias-look radial equivalent.

These are useful alternatives, but they should be treated as equivalents rather than automatic replacements. The recommended rim-width range for this conversion path is 6 to 8 inches, and the truck should also be checked for wheel compatibility, steering clearance, and any suspension or wheel changes that could affect how a radial option works on the vehicle.

Start by confirming the truck's original tire size, actual wheel diameter, and wheel width. On the 1982 Nissan Trucks 720, radial-equivalent choices are available for G78-15, E78-14, and 700-14, but the correct equivalent depends on the specific bias-ply size the truck uses.

A careful conversion also means comparing the new tire against the truck's wheel and body setup instead of choosing by rim diameter alone. Clearance at the fenders and steering, the condition of suspension components, and any aftermarket wheel changes should be reviewed so the radial choice suits the truck without assuming every equivalent will behave the same way.

The first consideration is the exact sub-model, because the 1982 Nissan Trucks 720 used six different primary sizes across 14-inch and 15-inch wheels. After that, the main decisions are whether the truck uses bias-ply or radial construction and whether the goal is a traditional truck look, a restoration-oriented appearance, or regular road use.

Once the size is confirmed, compare the available products by sidewall style, tire series, brand, and wheel-width compatibility where it is stated. That approach keeps the selection grounded in fitment first, then lets appearance and intended use guide the final choice instead of treating all 720 tires as interchangeable.

Depending on size, 1982 Nissan Trucks 720 tires are available in blackwall, wide whitewall, and narrow whitewall styles. The available sidewall treatment changes by tire size, so a 15-inch G78-15 bias-ply truck and a 14-inch radial King Cab do not necessarily have the same appearance options.

Sidewall style is mainly an appearance decision once the correct fitment has been established. A blackwall generally preserves a simpler utility-truck presentation, while whitewall options create a more styled or restoration-oriented look, so the best choice depends on whether the truck is being preserved for period character, casual cruising, or general display.

Available 1982 Nissan Trucks 720 tires come from Coker Classic, STA, Michelin, Phoenix, Vredestein, and BFGoodrich. The brand mix depends on the size, with some sizes centered on bias-ply offerings and others focused on radial products in a more modern metric format.

Brand choice should come after confirming the correct size and construction for the truck. Once that is settled, compare each option by sidewall style, tire series, rim-width specification where stated, and the kind of appearance or use the truck is meant to have, rather than assuming one brand covers every 720 application the same way.

A period-style choice for a 1982 Nissan Trucks 720 starts with the truck's correct primary size, then follows the construction type used by that sub-model. That may mean a bias-ply size such as G78-15, E78-14, or 700-14, or a radial size such as GR78-15, 185R14, or 195R14, depending on the truck.

After the fitment is confirmed, sidewall treatment and tire series shape the visual result. Whitewall options can create a more styled vintage presentation, while blackwalls often suit a more work-truck or understated look; if exact originality matters, marque-specific references and truck-specific historical documentation are worth checking before making a final appearance decision.

Tire construction can change the overall character of a restored 1982 Nissan Trucks 720 even when the wheel diameter stays the same. A bias-ply tire tends to preserve a more traditional vintage truck presentation, while a radial often gives the truck a later, more road-oriented look in both sidewall shape and general stance.

That matters most on sizes where a bias-ply fitment also has radial-equivalent options, such as G78-15, E78-14, and 700-14. Owners balancing restoration appearance with road use should decide early whether the truck's visual goal is faithful period style, a cleaner touring look, or a compromise that keeps vintage sizing language with radial construction.

Yes, modifications can affect tire fitment on a 1982 Nissan Trucks 720. Wheel changes, altered wheel width, suspension modifications, ride-height changes, and body or fender alterations can all change how a tire fits, even when the size matches the truck's original fitment category.

That is especially important on a model with both 14-inch and 15-inch applications and a mix of bias-ply and radial sizes. A truck that has aftermarket wheels or suspension work should be checked for clearance at steering lock and through suspension travel, rather than assuming the original fitment still applies without any adjustment.

Before driving a 1982 Nissan Trucks 720 on new tires, inspect the wheels for correct diameter and condition, confirm that the lug hardware is appropriate, and make sure the tires are seated properly and inflated to the needed pressure for the application. A basic visual check should also include clearance around fenders, suspension, and steering components.

After installation, it is smart to recheck pressure and look for any signs of rubbing or uneven positioning once the truck has been driven briefly. An older pickup can also reveal worn steering or suspension parts more clearly with fresh tires, so any pull, shake, or unusual wear pattern should be addressed before regular road use.

Tires on a collector 1982 Nissan Trucks 720 should be checked regularly for pressure, tread wear, sidewall cracking, cuts, bulges, and signs of slow air loss. Even a truck that sees limited mileage still needs inspections, because age, storage conditions, and long periods of sitting can affect tire condition as much as road use.

Good storage habits help preserve both bias-ply and radial tires. Keeping the truck away from prolonged sunlight, excess heat, moisture, and ozone sources can reduce deterioration, and occasional movement can help avoid long-term flat spotting; before any longer drive, give the tires and wheels another close inspection rather than relying on appearance alone.
