1963 Nissan L320 Tires

The 1963 Nissan L320 is associated with two primary tire sizes: 560-14 and 6.00-14. Both are bias-ply fitments and both use a 14-inch rim. The covered L320 Base sub-model can use either size, so the truck is not limited to one single fitment across every surviving example.

The practical decision is confirming which wheel setup is actually on the truck today. An L320 that still has stock-style narrow wheels may point you toward 560-14, while a truck set up for the wider size may call for 6.00-14. Checking wheel width, existing clearance, and the truck's overall stance helps narrow the choice before replacing tires.

The 1963 Nissan L320 uses a 14-inch rim with its primary tire fitments. Both 560-14 and 6.00-14 are built around that same rim diameter, so the diameter itself stays consistent even though the tire widths differ. That makes rim diameter one of the easier parts of the fitment picture on this truck.

Rim diameter is only part of the check, though. Wheel width still matters, especially when comparing a 560-14 against a 6.00-14. Before mounting new tires, verify the actual wheel dimensions on the vehicle, especially if the truck has been modified, restored with replacement wheels, or has been in service long enough that its original wheels may no longer be present.

On a 1963 Nissan L320, 560-14 is a numeric bias-ply tire size. The 5.60 refers to the tire's nominal section width in inches, and the 14 refers to the rim diameter in inches. It is an older sizing system commonly seen on compact trucks and passenger vehicles from the period.

Understanding that format helps when comparing it with 6.00-14, which is the same basic style of designation but with a slightly wider nominal section width. The size code does not tell the whole fitment story by itself, so the truck's actual wheel width, current stance, and available clearance should still be reviewed before settling on a replacement.

Start with the fitment basics: a 560-14 for a 1963 Nissan L320 should match the truck's 14-inch wheel and suit the wheel-width range used by that tire. In available BFGoodrich examples, 560-14 is offered in the Silvertown Classic Bias Ply series with blackwall, narrow whitewall, and wide whitewall sidewall treatments.

After size and wheel compatibility, the next decision is how the truck should look and be used. A blackwall gives a more utilitarian presentation, while whitewall styles lean more toward a restoration-oriented appearance. It also helps to compare product details such as rim-width specification, load capacity, and overall tire character so the truck's appearance and use stay in balance.

For the 1963 Nissan L320 in 560-14, available sidewall styles include blackwall, narrow whitewall, and wide whitewall. Those choices all stay within a vintage bias-ply presentation, but they create very different visual results once mounted on an early compact pickup. The tire's look can change the truck's personality almost as much as the wheel finish.

A buyer aiming for a work-truck feel may prefer blackwall, while a more dressed-up restoration may lean toward one of the whitewall options. Sidewall style should still come after fitment confirmation, since the correct size and wheel compatibility matter first. Once that is settled, sidewall choice becomes a useful way to tailor the truck's final period-style appearance.

Available 560-14 products for the 1963 Nissan L320 are offered by BFGoodrich. Those options appear in the Silvertown Classic Bias Ply series and include multiple sidewall treatments rather than multiple brand lines in the same size. That means the main comparison is less about brand switching and more about style and fitment details within the BFGoodrich range.

When brand variety is limited, selection becomes more focused on tire character. Compare the sidewall presentation you want, confirm the tire matches your wheel dimensions, and review the specifications that matter for a light vintage truck. That approach helps narrow the right tire even when the available lineup centers on one established vintage-style brand.

A period-style 1963 Nissan L320 starts with its original-type bias-ply fitment approach, using either 560-14 or 6.00-14 on 14-inch rims depending on the truck's wheel setup. Among the available 560-14 choices, the BFGoodrich Silvertown Classic Bias Ply line keeps the vintage construction and proportions that suit an early 1960s compact pickup.

From there, the right choice depends on the look you want the truck to project. Blackwall usually supports a more utilitarian presentation, while narrow or wide whitewalls create a dressier restoration feel. If strict originality matters, compare your tire choice against marque references, period photography, or other vehicle-specific historical sources before finalizing the sidewall treatment.

Tire construction has a visible effect on a restored 1963 Nissan L320 because bias-ply tires carry the period sizing format and visual character associated with trucks of this era. The L320's primary fitments are bias-ply sizes, so staying with that construction keeps the truck aligned with its original-era tire presentation.

Appearance is not only about the tread or sidewall color. The overall profile, the vintage numeric sizing, and the way the tire fills the wheel opening all contribute to how authentic the finished truck feels. That is why construction choice should be made alongside size confirmation, especially on a restoration where the goal is to preserve an early-1960s visual balance.

Yes, modifications can affect tire fitment on a 1963 Nissan L320 even when the tire size itself is correct for the model. Replacement wheels, altered wheel width, suspension changes, ride-height adjustments, and body or fender work can all change how a 560-14 or 6.00-14 tire sits on the truck.

A truck that has been restored or updated over the years should be treated as an individual setup rather than assumed to match original dimensions exactly. Measure the actual wheel diameter and width, inspect clearance at full steering travel, and look for rubbing marks before installing tires. Those checks are especially important on older pickups that may have had parts swapped over time.

Before driving a 1963 Nissan L320 on new tires, inspect the wheels for correct size and condition, confirm the tires are mounted to the proper rim diameter, and make sure inflation is set appropriately for the tire and vehicle use. A quick walkaround should also include checking lug hardware, valve stems, and visible clearance around fenders and suspension parts.

An older truck deserves a broader inspection beyond the tires alone. Look for steering looseness, worn suspension components, brake issues, and any signs that the truck has been sitting for long periods. After the first short drive, recheck air pressure and inspect for uneven contact, rubbing, or anything that suggests the wheel and tire package needs closer attention.

560-14 tires on a collector 1963 Nissan L320 should be maintained with regular pressure checks, visual inspections, and periodic review for sidewall cracking, tread wear, bulges, cuts, or slow air loss. Vintage trucks that see infrequent use can develop tire issues from age and storage conditions long before mileage becomes the main concern.

Good maintenance also means protecting the truck from prolonged heat, direct sunlight, standing moisture, and ozone sources during storage. Move the vehicle occasionally so the tires are not left loaded in one position for too long, and inspect them before every outing. That routine helps preserve both safety and appearance on an older light truck that spends much of its life parked.
