The 1978 Nissan 510 belongs to the later chapter of Nissan’s long-running 510 name, when compact practicality, clean styling, and everyday drivability mattered as much as enthusiast appeal. For owners today, tire selection comes down to matching the exact body style, because this model year uses both a modern-style 165R13 radial and a period numeric 6.45-13 bias-ply fitment on 13-inch rims. That creates a meaningful split between radial-equipped hatchback and wagon applications and the bias-ply setup used on the two-door sedan. The right choice depends on preserving the vehicle’s intended look and construction while also confirming the wheels actually on the car.
Which Tire Size Is Right for The 1978 Nissan 510
The 1978 Nissan 510 uses two primary tire sizes, and the correct one depends on the specific body style rather than a simple across-the-board fitment. Both sizes are built around a 13-inch rim, but one is a radial and the other is a bias-ply tire, so the first step is confirming whether the car is a Hatchback, Sedan 2 Dr., or Wagon before choosing a replacement.
165R13 is a Euro-metric radial size in which 165 refers to the nominal section width in millimeters, R indicates radial construction, and 13 is the wheel diameter in inches. On the 1978 Nissan 510, this size serves the hatchback and wagon applications and gives the car a more modern radial-style fitment within its original 13-inch wheel format. Available choices include Michelin and Dunlop products, with blackwall presentation and tire series such as Michelin XAS-FF, Michelin XAS, and SP Sport Aquajet. It is the size to evaluate when your 510 uses the radial-equipped body styles and you want to stay with that construction.
6.45-13 is a numeric bias-ply size in which 6.45 represents the nominal section width in inches and 13 designates the wheel diameter. On the 1978 Nissan 510, this size belongs to the Sedan 2 Dr. application and reflects a more traditional bias-ply sizing system than the radial fitments used on other sub-models. Bias-ply construction matters here because it affects both the tire’s appearance and the overall character of a period-style replacement. This is the size to confirm when restoring or maintaining a two-door sedan that still uses its original-style wheel and tire setup.
Sub-model fitment matters on the 1978 Nissan 510 because tire size and construction change by body style. The hatchback and wagon share the same radial size, while the two-door sedan uses a different bias-ply fitment, so identifying the exact sub-model should come before comparing tire options.

1978 Nissan 510 Hatchback
The 1978 Nissan 510 Hatchback uses the 165R13 radial size on a 13-inch rim. That keeps tire selection focused on choosing among the available radial product lines while preserving the correct size format for the hatchback application.
The 1978 Nissan 510 Sedan 2 Dr. uses the 6.45-13 bias-ply size on a 13-inch rim. Tire choice here centers on retaining the proper numeric bias-ply fitment and confirming that the car still has the wheel setup intended for that traditional size.
The 1978 Nissan 510 Wagon uses the 165R13 radial size on a 13-inch rim. That makes the wagon’s decision less about multiple fitments and more about selecting the right radial tire series and confirming wheel compatibility before installation.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 1978 Nissan 510 Tires for Sale
Available 165R13 choices center on radial blackwall tires from Michelin and Dunlop, including Michelin XAS-FF, Michelin XAS, and SP Sport Aquajet. These options let buyers compare tire series, brand, and rim-width compatibility within the correct 13-inch radial fitment.
Owners usually need to sort out three things on a 1978 Nissan 510: which body style they have, whether it uses the radial or bias-ply fitment, and how to choose the right tire for restoration-minded use or regular road driving.
Tire Size & Fitment
What tire size fits a 1978 Nissan 510?
The 1978 Nissan 510 uses two different primary tire sizes. The Hatchback and Wagon use 165R13 radial tires, while the Sedan 2 Dr. uses a 6.45-13 bias-ply tire. All of these fitments are built around a 13-inch rim, but the size format and construction are not the same across every version of the car.
That means the right starting point is the exact body style, not just the year and model name. A hatchback or wagon owner should stay focused on 165R13 radial options, while a two-door sedan owner should confirm the car still uses the wheel and tire setup intended for 6.45-13 before choosing a replacement.
What size rim does a 1978 Nissan 510 use?
The 1978 Nissan 510 uses a 13-inch rim with both of its primary tire fitments. The 165R13 radial and the 6.45-13 bias-ply size are both intended for 13-inch wheels, so wheel diameter remains consistent even though the tire construction and sizing systems differ by sub-model.
Rim diameter is only part of the fitment picture, especially on an older vehicle. Checking the actual wheel on the car still matters, because replacement wheels, later take-off wheels, or other changes can alter what tire size works properly and how the tire sits in relation to suspension and body clearance.
Do all 1978 Nissan 510 sub-models use the same tire size?
No, 1978 Nissan 510 sub-models do not all use the same tire size. The Hatchback and Wagon share the 165R13 radial fitment, while the Sedan 2 Dr. uses a 6.45-13 bias-ply tire. The difference is more than just numbering, since the car can also vary by tire construction depending on body style.
That split makes sub-model identification especially important before comparing products. A buyer who assumes every 1978 510 uses the same size can easily end up shopping the wrong category, so it is worth confirming the exact body style and checking the wheels already on the car before moving ahead.
Bias-Ply & Radial Options
Is 6.45-13 a bias-ply or radial tire for the 1978 Nissan 510?
For the 1978 Nissan 510, 6.45-13 is a bias-ply tire size. It is the primary fitment for the Sedan 2 Dr. and uses a vintage numeric sizing format rather than the Euro-metric radial format used on the hatchback and wagon. That makes it a distinct construction choice within the same model year.
Construction affects more than the label on the sidewall. A sedan owner considering replacement tires should first confirm that the car still has the correct 13-inch wheel setup for this application, then decide whether the goal is to preserve a traditional bias-ply presentation or evaluate a different setup through a more involved fitment review.
Is 165R13 a bias-ply or radial tire for the 1978 Nissan 510?
On the 1978 Nissan 510, 165R13 is a radial tire size. It is used on the Hatchback and Wagon and follows a Euro-metric sizing convention, with 165 as the nominal section width in millimeters, R for radial construction, and 13 for the wheel diameter. That makes it the radial fitment within this model range.
For buyers replacing tires on those sub-models, the main task is not deciding between multiple primary sizes but choosing the right radial product within 165R13. Brand, tire series, sidewall presentation, and wheel compatibility all matter, especially if the car has seen wheel changes or has been sitting long enough to need a broader safety inspection.
Should I use bias-ply or radial tires on a 1978 Nissan 510?
The answer depends on which 1978 Nissan 510 body style you own and what tire fitment belongs on it. The Hatchback and Wagon use 165R13 radial tires, while the Sedan 2 Dr. uses a 6.45-13 bias-ply size. So the first priority is matching the tire to the sub-model’s actual fitment rather than choosing construction in the abstract.
Beyond that, the decision often comes down to preserving the vehicle’s intended setup versus adapting it. Owners should verify the wheel diameter and overall wheel setup already on the car, because an older 510 may no longer be on its original wheels, and that can change what tire choice makes sense for appearance and road use.
Choosing the Right Tire
What should I consider when choosing a 165R13 tire for a 1978 Nissan 510?
A 165R13 tire choice for a 1978 Nissan 510 starts with confirming that the car is a Hatchback or Wagon, since those are the sub-models that use this radial size. From there, the main comparisons are brand, tire series, blackwall appearance, and wheel compatibility within the available 13-inch radial products.
Michelin and Dunlop both appear in this size, with series such as Michelin XAS-FF, Michelin XAS, and SP Sport Aquajet. It is also smart to compare the wheel dimensions on the car against the tire’s intended rim-width range where that specification is available, especially if the 510 has replacement wheels or a modified stance.
What sidewall styles are available for 1978 Nissan 510 tires?
The available 165R13 radial products for the 1978 Nissan 510 use a blackwall sidewall style. That gives hatchback and wagon owners a straightforward visual direction when choosing among the current radial options in this size, since the product differences center more on brand and tire series than on contrasting sidewall treatments.
Appearance still matters on a late-1970s compact, particularly if the car is being preserved or restored with a period-minded look. Even with a simple blackwall selection, the final presentation can still be influenced by the exact tire series, the wheel design on the car, and whether the vehicle remains close to its original ride height and stance.
What brands offer tires for the 1978 Nissan 510?
For the 1978 Nissan 510, the available 165R13 radial products come from Michelin and Dunlop. Michelin appears with the XAS-FF and XAS series, while Dunlop is represented by the SP Sport Aquajet. Those offerings give buyers more than one established brand to consider within the correct radial size for the hatchback and wagon applications.
Brand alone should not be the only filter. It helps to compare the tire series themselves, confirm the wheel dimensions on the vehicle, and think about how the car will be used, whether that means occasional local driving, a preservation-focused presentation, or regular fair-weather road miles on an otherwise stock-style setup.
Restoration & Appearance
Which tire should I choose for a period-style 1978 Nissan 510?
A period-style tire choice for a 1978 Nissan 510 starts with the sub-model’s original fitment type. The Hatchback and Wagon use 165R13 radial tires, while the Sedan 2 Dr. uses a 6.45-13 bias-ply size. Matching the correct size and construction to the body style is the first step toward a restoration-oriented appearance.
After that, the decision becomes more visual and use-based. A buyer preserving a stock-looking hatchback or wagon can compare radial tire series with an eye toward traditional presentation, while a sedan owner will usually want to keep the numeric bias-ply format in focus and verify the wheel setup before choosing a replacement.
Does correct tire fitment matter for a 1978 Nissan 510 restoration?
Correct tire fitment matters on a 1978 Nissan 510 restoration because the model year does not use one universal size across every body style. The hatchback and wagon use 165R13 radial tires, while the two-door sedan uses a 6.45-13 bias-ply size. Using the wrong format can quickly change the car’s stance and overall character.
Restoration-minded owners usually get the best results by confirming the sub-model first, then checking whether the car still has the wheel setup intended for that fitment. When exact historical accuracy is the goal, marque references and vehicle-specific documentation can help settle appearance details that go beyond basic size and construction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1978 Nissan 510?
Yes, modifications can affect tire fitment on a 1978 Nissan 510 even when the correct factory-style tire size is known. Aftermarket wheels, changes in wheel width, altered offset, lowering, suspension work, or body modifications can all change how a 165R13 or 6.45-13 tire sits within the wheel opening and near steering components.
That is why the actual wheel and vehicle setup should be checked before ordering replacement tires for an older 510. A car that no longer sits at stock height or no longer uses stock-style wheels may need extra attention to clearance at the fender edge, inside sidewall, and full-lock steering position.
What should I inspect before driving a 1978 Nissan 510 on new tires?
Before driving a 1978 Nissan 510 on new tires, inspect the wheels for damage or distortion, confirm lug hardware condition, and make sure the tire size matches the car’s body style. It is also wise to check suspension bushings, steering components, and alignment condition so the new tires are not immediately affected by unrelated chassis issues.
Collector-era cars often spend long periods parked, which can hide problems until road use begins again. Tire pressure should be set correctly, and the car should be checked for rubbing, unusual vibration, air loss, or pull during the first miles so any wheel or fitment issue can be caught before regular driving resumes.
How should tires on a collector 1978 Nissan 510 be maintained?
Tires on a collector 1978 Nissan 510 should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even if tread wear remains light. Sidewall cracking, flat spotting, bulges, cuts, and slow air loss deserve attention because older hobby cars often accumulate time in storage faster than they accumulate miles.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged heat, direct sunlight, standing moisture, and ozone sources can help protect the tires, and occasional inspections of both the tire and wheel assembly make it easier to catch problems before a local cruise or a longer seasonal drive.
