1985 Nissan Trucks 720 Tires

A 1985 Nissan Trucks 720 can use 185/70R14, 185R14, 195/75R14, 205/75R14, 215/75R15, or 225/75R15, depending on the exact sub-model. The 4x2 King Cab and regular cab versions use 185/70R14, Deluxe 4x2 King Cab and XE use 185R14, Deluxe 4x2 Long Bed and H.D. use 195/75R14, Sport Truck 4x2 uses 205/75R14, Deluxe 4x4 uses 215/75R15, and Sport Truck 4x4 uses 225/75R15.

That range means the first step is identifying the truck's exact configuration rather than choosing by appearance alone. Cab style, trim, drive type, and wheel diameter all matter on the 720, and older trucks are often changed from their original wheel setup. Confirm the sub-model and measure the wheel diameter on the truck before selecting a tire.

The 1985 Nissan Trucks 720 uses either a 14-inch or 15-inch rim, depending on the sub-model and tire size. The 14-inch applications are tied to 185/70R14, 185R14, 195/75R14, and 205/75R14, while the 15-inch applications use 215/75R15 or 225/75R15. All of the primary fitments for this truck are radial sizes, but they do not all share the same wheel diameter.

Wheel diameter is the most important fitment check before anything else, because a 14-inch tire will not mount on a 15-inch wheel and vice versa. It also helps to confirm actual wheel width if the truck has aftermarket rims, aluminum wheels, or a modified stance, since product rim-width ranges can vary within the same size.

The 1985 Nissan Trucks 720 was offered in multiple configurations, including 4x2, 4x4, King Cab, regular cab, long bed, H.D., XE, Deluxe, and Sport Truck versions. Those different uses and trim packages account for the six primary tire sizes, with some trucks staying on 14-inch wheels and others moving to larger 15-inch fitments. The tire size is tied to the specific truck version rather than the 720 name alone.

That matters because two 1985 720 pickups can look similar at a glance but still require different tires. A truck with replacement wheels or suspension changes may also no longer match its original configuration exactly. Checking the sub-model name, current wheel diameter, and the size already mounted on the vehicle helps narrow the right starting point before comparing tire styles.

Start with the correct primary size for the exact 1985 Nissan Trucks 720 sub-model, then match the tire to the truck's current wheel diameter and intended use. A 4x2 truck, a Sport Truck, and a 4x4 do not all share the same fitment. Once the correct size is confirmed, compare radial construction, sidewall style, tire series, rim-width compatibility, and any load figures that matter for how the truck will be used.

An appearance-focused truck may lean toward a blackwall, whitewall, or redline presentation, while a utility-oriented 4x4 may call for a different look within the correct size. It also helps to inspect whether the truck still has its original-style wheels or has been modified over the years. Choosing in the right order keeps the visual decision from overriding fitment.

Sidewall choices for the 1985 Nissan Trucks 720 vary by tire size, but the available styles include blackwall, narrow whitewall, wide whitewall, redline, and RBL. Smaller 14-inch sizes such as 185/70R14 and 185R14 include blackwall and whitewall options, while 205/75R14 adds redline choices. The 15-inch truck sizes also include several whitewall options, and 215/75R15 includes an RBL all-terrain style.

The right sidewall depends on the truck's role and presentation. A simple 4x2 may suit a clean blackwall or narrow whitewall, while a restoration-minded build may call for a broader whitewall treatment in the correct size. Sidewall style should be chosen after confirming the proper fitment, since not every look is offered in every 720 tire size.

Tires for the 1985 Nissan Trucks 720 are available from BFGoodrich, Avon, Dunlop, Michelin, Vredestein, Coker Classic, American Classic, Maxxis, Travelstar, Tornel, and Phoenix, depending on size. Brand availability changes across the six primary fitments, so a 14-inch 4x2 size and a 15-inch 4x4 size will not necessarily have the same mix. Several sizes also include more than one tire series within the same brand family.

Brand choice is best treated as one part of a broader comparison rather than the first decision. Once the right size is confirmed, compare the available brands by sidewall style, rim-width specification, load information, and the overall look you want on the truck. That approach keeps the selection grounded in fitment instead of chasing a brand that may suit a different 720 configuration.

A period-style 1985 Nissan Trucks 720 tire choice starts with the truck's actual factory-size family for its sub-model, not with a universal 720 fitment. Once the correct size is established, the available radial choices include blackwall, narrow whitewall, wide whitewall, redline, and RBL presentations depending on the application. That gives a broad range of looks while staying within the proper size for the truck's configuration.

For a restoration-oriented build, it helps to decide whether the goal is a stock-looking work truck, a dressed-up trim package, or a sportier presentation. Exact originality claims should be checked against vehicle-specific literature or marque references when details matter closely. Starting with the right size and wheel diameter is what keeps the truck visually convincing.

On the 1985 Nissan Trucks 720, the primary fitments are already radial, so the appearance question is less about bias-ply versus radial and more about size format and sidewall treatment. A 185R14 truck presents differently from a 185/70R14 truck, and a 205/75R14 Sport Truck can take on a very different character depending on whether it wears a redline or whitewall sidewall.

That means visual accuracy comes from preserving the truck's correct size family first, then selecting the sidewall style that best matches the build. Wheel changes can alter the overall impression quickly, especially when a 14-inch truck is converted to a 15-inch setup or vice versa. Keeping the proper tire format usually matters as much as the brand name on a restored pickup.

Yes, modifications can affect tire fitment on a 1985 Nissan Trucks 720, especially because this model already uses several different factory tire sizes across 14-inch and 15-inch wheel applications. Aftermarket wheels, altered wheel widths, suspension lifts, lowering, and body changes can all change what clears the truck properly. That becomes especially important on 4x4 and Sport Truck versions where the original size is specific to the sub-model.

A modified truck should be checked for wheel diameter, wheel width, and available clearance at the fenders and steering components before selecting a tire. It also helps to compare the size currently on the truck with the intended replacement rather than assuming the vehicle still matches its original setup. Small pickups often see decades of changes, so verification matters.

Before driving a 1985 Nissan Trucks 720 on new tires, inspect the wheels for damage, confirm the correct tire size and wheel diameter, and make sure the tires are mounted and inflated properly. It is also wise to check brake condition, steering components, wheel bearings, and suspension wear, since problems in those areas can affect how the truck tracks and how evenly the new tires wear.

An older pickup that has spent time parked deserves an especially careful once-over. Look at clearance with the wheels turned, watch for rubbing under load, and recheck tire pressure after the first few drives. If the truck has aluminum wheels, aftermarket wheels, or a changed ride height, those details should be reviewed before any longer road use.

Tires on a 1985 Nissan Trucks 720 should be inspected regularly, with a quick visual check before normal driving and a more thorough inspection at routine service intervals or before longer trips. Older trucks and collector-driven vehicles often cover fewer miles, so age and condition can matter as much as tread depth. Cracks, bulges, cuts, uneven wear, and repeated air loss all deserve prompt attention.

A truck that sits for long periods should also have its tire pressure checked more often than its mileage alone would suggest. Storage conditions, sunlight, heat, and long stationary periods can all affect tire condition over time. Frequent inspection is especially useful on the 720 because its sub-models use different tire sizes, and replacing one incorrectly can create avoidable fitment issues.
