1979 Nissan 810 Tires

The 1979 Nissan 810 uses a 185/70R14 radial tire. That size applies to the covered Sedan & Wagon sub-model, making fitment simpler than on vehicles that used multiple tire sizes across the lineup.

Even with one primary size, it is still worth checking the car's actual wheels before ordering tires. A 14-inch rim is part of the fitment, and wheel-width differences or aftermarket wheel changes can affect which 185/70R14 tire is the most appropriate choice.

The 1979 Nissan 810 uses a 14-inch rim with its 185/70R14 tire size. The tire's size designation ends in 14, which corresponds to the wheel diameter in inches and confirms the basic rim diameter needed for this fitment.

Rim diameter is only part of the check before mounting new tires. Wheel width matters too, especially since available 185/70R14 products have different approved rim-width ranges, so the actual wheel on the car should be measured and compared before making a final selection.

The covered 1979 Nissan 810 Sedan & Wagon sub-models share the same 185/70R14 radial tire size. That means the tire-size decision is consistent across those versions rather than split by separate fitments or different rim diameters.

Shared size does not mean every car is still on its original wheel setup decades later. A careful owner should confirm that the car still wears 14-inch wheels and that no suspension or wheel changes were made that would affect clearance or rim-width compatibility.

Start with the correct size, 185/70R14, and make sure the tire is suited to the 14-inch wheels on the car. From there, the choice comes down to style, rim-width compatibility, brand, and whether the car is being preserved with a more traditional look or used for regular road driving.

A buyer comparing options should also pay attention to sidewall treatment, product series, and any load information supplied with the tire. That approach helps narrow the field without guessing, especially on an older car that may have seen wheel changes over the years.

185/70R14 tires for the 1979 Nissan 810 are available in both blackwall and wide whitewall styles. Most of the available options use a blackwall presentation, while the BFGoodrich Silvertown Radial offers a 2.25-inch wide whitewall for a more distinctive vintage appearance.

Sidewall choice mainly affects the car's visual character rather than the basic fitment size. A blackwall usually suits a cleaner late-1970s road-car look, while a wide whitewall can push the presentation toward a more restoration-oriented or customized appearance on the same wheel diameter.

The 1979 Nissan 810's 185/70R14 size is available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. Those choices span several tire series, including Silvertown Radial, CR6ZZ, Sport Classic, Michelin XAS, and Sprint Classic.

Brand alone should not make the decision. It is smarter to compare each tire's sidewall style, approved rim-width range, and the type of driving the car will actually see, whether that means casual weekend use, show presentation, or regular road miles on a vintage Nissan.

A period-style starting point for a 1979 Nissan 810 is staying with the correct 185/70R14 radial size on a 14-inch wheel. Within that size, blackwall options generally preserve the car's late-1970s import character, while the available wide whitewall creates a more customized vintage presentation.

Appearance goals should guide the final choice as much as fitment. Owners aiming for a restoration-oriented result should compare sidewall style and tire series carefully, then confirm details against photos, marque references, or other vehicle-specific history if exact presentation matters.

On the 1979 Nissan 810, construction is straightforward because the primary fitment is already radial. That means the visual difference between available tires is shaped more by sidewall style and tread-era character than by a choice between bias-ply and radial construction.

For a restored car, the biggest appearance decision is usually blackwall versus wide whitewall in the correct 185/70R14 size. Keeping the proper size and wheel diameter helps the car retain the right stance, while sidewall choice fine-tunes whether the finished look feels restrained or more stylized.

Yes, modifications can affect tire fitment on a 1979 Nissan 810 even when the intended size remains 185/70R14. Changes such as aftermarket wheels, altered wheel width, suspension work, or body modifications can all influence how well a tire works within the available space.

A modified car should be checked for wheel diameter, actual rim width, steering clearance, and fender clearance before new tires are mounted. That is especially important on an older vehicle, where long ownership histories sometimes leave a mix of parts that no longer match the original setup.

Before driving a 1979 Nissan 810 on new tires, inspect the wheels for correct diameter and condition, confirm that the tires are seated properly, and make sure pressure is set appropriately for the tire and vehicle. It also helps to check for rubbing at full steering lock and during suspension movement.

An older car deserves a broader once-over before road use. Look at wheel bearings, suspension wear, brake condition, and any signs of uneven ride height, since those issues can affect how the new tires behave and how evenly they wear once the car is back in service.

185/70R14 tires on a collector 1979 Nissan 810 should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and uneven wear, and protected from long periods of heat, sunlight, and ozone exposure. Low-mileage collector cars can hide tire aging even when tread still looks usable.

Routine checks are especially important before seasonal driving or longer trips. A good habit is to inspect air loss, sidewall condition, and tread surface after storage, then confirm that the car still sits and steers normally, since tire condition can change long before obvious failure appears.
