The 1973 Nissan PL620 sits squarely in the era when compact Japanese pickups earned a reputation for straightforward utility, tidy dimensions, and everyday durability. Owners restoring or maintaining one today usually want a tire that looks right on the truck while still matching its original-style proportions. For this model, the primary fitment is a 6.00-14 bias-ply tire on a 14-inch rim. That keeps the tire decision focused less on sorting through multiple sizes and more on choosing the right period-style construction and overall presentation. Before making a final choice, it is worth confirming the truck still has the correct wheel setup and has not been changed with later wheels or suspension modifications.
Which Tire Size Is Right for The 1973 Nissan PL620
The 1973 Nissan PL620 uses one primary tire size: 6.00-14. That is a bias-ply fitment on a 14-inch rim, and the covered PL620 Pickup sub-model uses the same size, so the main decision is choosing the right tire within that fitment while keeping wheel condition, intended appearance, and overall vehicle setup in mind.
A 6.00-14 tire uses the older numeric bias-ply sizing system, where 6.00 refers to the nominal section width in inches and 14 identifies the wheel diameter. On a 1973 Nissan PL620, this size maintains the traditional bias-ply construction associated with the truck's original era and overall stance. Numeric bias-ply tires appeal to owners who want a period-style look rather than a modern metric presentation. This size makes the most sense when the goal is preserving the truck's vintage character while staying with the correct 14-inch wheel format.
Tire fitment is straightforward on the covered 1973 Nissan PL620 sub-model. The PL620 Pickup uses the same primary size, so selection comes down to choosing the right 6.00-14 bias-ply tire and confirming the truck still carries the proper 14-inch wheels.

Frequently Asked Questions
These FAQs focus on 1973 Nissan PL620 tire size, 14-inch rim fitment, bias-ply construction, restoration-minded selection, and the checks worth making before putting a vintage compact pickup back into regular road use.
Tire Size & Fitment
What tire size fits a 1973 Nissan PL620?
The 1973 Nissan PL620 uses a 6.00-14 tire. That is the primary fitment for the covered PL620 Pickup configuration, and it is a bias-ply size rather than a modern metric radial size.
Using the right size starts with confirming that the truck still has 14-inch wheels in the proper vintage format. On an older pickup, replacement wheels, brake changes, or later modifications can affect what is currently on the vehicle, so matching the tire to the actual wheel diameter is just as important as matching the size code.
What size rim does a 1973 Nissan PL620 use?
The 1973 Nissan PL620 uses a 14-inch rim with its 6.00-14 tire fitment. The 14 at the end of the tire size identifies the wheel diameter the tire is built to mount on.
That does not mean every 14-inch wheel is automatically suitable for the truck. Older vehicles may have had wheel swaps over the years, so it is smart to verify the actual wheel width, overall condition, and any clearance changes before mounting new tires, especially if the truck has been modified or restored with non-original hardware.
Does the 1973 Nissan PL620 Pickup use the same tire size?
Yes. The covered 1973 Nissan PL620 Pickup uses the same 6.00-14 bias-ply tire size as the model core. That makes fitment simpler than on vehicles that split tire sizes across multiple trims or wheel packages.
Even with one shared size, it still helps to inspect what is on the truck now. A PL620 that has been updated with later wheels, changed ride height, or different suspension parts may need a closer wheel-and-clearance check before replacing tires, even when the goal is returning it to a more traditional period-style setup.
Choosing the Right Tire
What should I consider when choosing a 6.00-14 tire for a 1973 Nissan PL620?
Start with the basics: the 1973 Nissan PL620 calls for a 6.00-14 bias-ply tire on a 14-inch rim. That means the first priority is staying with the correct size and construction style that suits the truck's era and intended appearance.
From there, think about how the truck will be used and how original-looking you want it to remain. A restoration-oriented PL620 may call for a more traditional visual presentation, while a regularly driven truck still needs close attention to wheel condition, tire age, sidewall health, and any evidence that the current wheel setup differs from stock dimensions.
How do I choose between the available 6.00-14 tires for a 1973 Nissan PL620?
Choosing among 6.00-14 tires for a 1973 Nissan PL620 is mostly about matching the tire to the truck's purpose. Since the size itself is fixed, the real differences usually come down to overall period-style appearance, construction consistency, and how closely the tire suits a restoration or preservation approach.
A truck built for shows may call for a tire that complements its vintage presentation, while a driver-quality PL620 still benefits from careful attention to age, condition, and wheel compatibility. It also helps to inspect suspension height and fender clearance so the selected tire works with the truck as it sits today, not just as it left the factory era.
Why is staying with the correct 6.00-14 size important on a 1973 Nissan PL620?
The 6.00-14 size helps preserve the proportions and wheel relationship intended for the 1973 Nissan PL620. On a compact pickup from this period, tire sizing has a noticeable effect on stance, visual balance, and how naturally the truck fills the wheel openings.
Changing away from the original-style size without careful comparison can introduce issues with wheel fit, turning clearance, or the truck's overall appearance. Owners returning a PL620 to road use or restoration duty usually benefit from verifying the existing wheel setup first, then selecting a tire that stays aligned with the truck's proper 14-inch format.
Restoration & Appearance
Which tire should I choose for a period-style 1973 Nissan PL620?
A period-style 1973 Nissan PL620 starts with the correct 6.00-14 bias-ply size. That sizing format matches the truck's early-1970s utility character and gives the vehicle the traditional tire profile expected on a compact pickup of this era.
Appearance-focused buyers should think beyond size alone and consider how the tire complements the truck's finish, wheel style, and restoration goals. When exact originality matters, it is wise to compare the truck against marque references, surviving examples, or restoration documentation so the finished look reflects the PL620's period character as closely as possible.
Does correct tire fitment matter for a 1973 Nissan PL620 restoration?
Yes, correct tire fitment matters because tire size has a strong effect on how a restored 1973 Nissan PL620 sits and presents itself. A 6.00-14 bias-ply tire supports the proper vintage look much better than an obviously modern size that changes the truck's visual proportions.
Fitment also affects practical details during a restoration. The right size helps avoid clearance surprises and keeps the relationship between tire and wheel more appropriate for the truck's original-era setup. Before final assembly, it is worth checking wheel diameter, wheel condition, and suspension height so the restored truck looks settled and usable rather than mismatched.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 Nissan PL620?
Yes. Modifications can change tire fitment on a 1973 Nissan PL620 even when the truck originally used a 6.00-14 bias-ply tire. Wheel swaps, suspension changes, brake conversions, or altered ride height can all affect the space available around the tire.
A truck with aftermarket wheels should be checked for actual wheel diameter and width before new tires are chosen. Steering clearance, fender clearance, and overall stance matter as well, especially on an older pickup that may have seen decades of repairs or customization, so the current setup should guide the final fitment decision.
What should I inspect before driving a 1973 Nissan PL620 on new tires?
Before driving a 1973 Nissan PL620 on new tires, inspect the wheels for damage, corrosion, and proper diameter, and make sure the tires are mounted and inflated correctly. It is also smart to check for any rubbing at the fenders, suspension, or steering components once the truck is back on the ground.
An older pickup deserves a broader road-use inspection as well. Look over the suspension, steering linkage, wheel bearings, and brakes, then recheck tire pressure after the first few drives. Collector and hobby vehicles often sit for long periods, so a cautious first outing helps reveal clearance, vibration, or handling issues before they become larger problems.
How should 6.00-14 tires on a collector 1973 Nissan PL620 be maintained?
6.00-14 tires on a collector 1973 Nissan PL620 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long idle periods on rough or damp surfaces. Even low-mileage tires need routine attention because age and storage conditions matter on vintage vehicles.
Storage plays a major role in long-term condition. Keeping the truck away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber, and occasional movement can reduce flat-spotting during extended downtime. Before any longer drive, it is wise to check air pressure, tread condition, and the overall health of each tire rather than relying on appearance alone.
