1970 Nissan L320 Tires

The 1970 Nissan L320 uses two primary tire sizes: 560-14 and 6.00-14. Both are bias-ply sizes designed for 14-inch rims, and the 1970 Nissan L320 Base is associated with both of them rather than one single universal fitment for every truck you may see in service today.

That means the safest starting point is checking the size already mounted on the truck and confirming the wheel dimensions before ordering a replacement. Since both sizes belong to the same rim diameter but represent different fitment choices, owners should verify wheel width, overall clearance, and the truck’s present configuration rather than assuming one can automatically replace the other.

The 1970 Nissan L320 uses a 14-inch rim diameter with its primary tire fitments. Both 560-14 and 6.00-14 are built around that same 14-inch wheel diameter, so the rim diameter itself stays consistent even though the truck is associated with two different numeric bias-ply tire sizes.

Rim diameter is only part of the fitment picture on a vintage truck like the L320. The next check is wheel width, because tire size selection depends on more than just the bead seat diameter. If the truck has replacement wheels, older repairs, or later modifications, confirm the actual wheel dimensions before choosing between the two available sizes.

The 1970 Nissan L320 is associated with two primary sizes, 560-14 and 6.00-14, both in bias-ply construction. That does not mean the sizes are interchangeable in every case; it means the truck can be encountered with more than one correct primary fitment depending on its wheel setup and how it has been maintained over time.

For an owner, the practical takeaway is to identify what is actually on the truck before selecting a replacement. Measuring the wheel, reading the current sidewall, and checking available clearance around suspension and bodywork are more useful than choosing by year and model alone. Vintage trucks often remain in service long enough to pick up wheel changes that affect tire selection.

A 560-14 tire for a 1970 Nissan L320 should first be matched to the truck’s actual wheel setup, since this is a numeric bias-ply size built for a 14-inch rim and a specific rim-width range. After that, the key differences within the available choices are sidewall presentation, with blackwall, narrow whitewall, and wide whitewall versions offered in the same basic tire series.

The right choice depends on how the truck will be used and how original-looking you want it to appear. A blackwall often suits a more utilitarian presentation, while whitewall variations shift the truck’s visual character toward a more restoration-oriented look. Load capacity, wheel width, and the condition of older rims should also be checked before mounting any new bias-ply tire.

For the 1970 Nissan L320, available 560-14 tire choices include blackwall, narrow whitewall, and wide whitewall sidewall styles. Those options all stay within the same BFGoodrich Silvertown Classic Bias Ply family, so the basic construction remains period-style bias-ply while the outward appearance changes substantially from one version to the next.

That makes sidewall selection mostly an appearance decision rather than a change in tire type. Owners restoring a truck with a simple working-truck look may lean toward blackwall, while a whitewall can create a more dressed-up vintage presentation. Sidewall style should still come after confirming that 560-14 is the size actually suited to the truck’s wheel and fitment setup.

Within the available products for this 1970 Nissan L320 fitment, BFGoodrich appears in 560-14 through the Silvertown Classic Bias Ply line. Those options stay focused on traditional bias-ply construction and differ mainly by sidewall style rather than by a wide spread of competing constructions or modern replacement formats.

That means brand comparison is less of the story here than size confirmation and appearance choice. Before focusing on brand, verify whether the truck needs 560-14 or 6.00-14 and make sure the wheels match the tire’s rim requirements. Once the fitment is confirmed, the available BFGoodrich choices let the buyer decide how traditional or dressy the finished look should be.

A period-style 1970 Nissan L320 should stay with one of its primary bias-ply sizes, either 560-14 or 6.00-14, after confirming which fitment belongs on the truck’s current wheels. For owners using 560-14, the available BFGoodrich Silvertown Classic Bias Ply options provide a traditional construction and a vintage presentation that suits an older compact pickup well.

The final choice depends on whether the goal is a plain working-truck look or a more restoration-oriented finish. Blackwall keeps the appearance simple, while narrow or wide whitewall treatments add more visual emphasis. If exact originality matters beyond general period style, compare the truck against marque references, old photos, or restoration records before settling on a sidewall treatment.

Correct tire fitment matters on a 1970 Nissan L320 restoration because tire size and construction strongly influence the truck’s stance, visual balance, and road manners. Since this model is associated with both 560-14 and 6.00-14 bias-ply sizes, choosing the wrong one for the wheels actually on the truck can change more than appearance alone.

A thoughtful restoration should confirm wheel diameter, wheel width, and the truck’s current clearance before tires are mounted. That helps preserve a believable vintage look while avoiding fitment surprises once the truck is back on the ground. Even on a utility pickup, the tire choice is one of the most visible finishing details in the entire restoration.

Yes, modifications can affect tire fitment on a 1970 Nissan L320 even when the truck still uses one of its primary 14-inch tire sizes. Aftermarket wheels, altered ride height, brake changes, and body or suspension work can all change how much room is available around the tire, especially on a compact vintage pickup.

That is why modified trucks should be checked by measurement rather than by assumption. Confirm wheel width and diameter, inspect steering and fender clearance through the full range of motion, and compare the mounted setup against the intended tire size before installation. A small truck leaves less margin for error when wheel and suspension dimensions have changed.

Before driving a 1970 Nissan L320 on new tires, inspect the wheels for rust, cracks, bent flanges, and bead-seat damage, then verify that the chosen size matches the actual rim setup. It also helps to check lug hardware, wheel mounting surfaces, valve stems, and the condition of suspension and steering components that influence how the truck tracks on the road.

After the tires are mounted, confirm inflation, look for any interference at full steering lock, and watch for unusual vibration or pull on the first short drive. Vintage trucks that have sat for long periods deserve extra attention to wheel bearings, brake function, and alignment as well, since fresh tires can reveal underlying mechanical issues rather than causing them.

560-14 tires on a collector 1970 Nissan L320 should be maintained with regular pressure checks, routine visual inspection, and protection from long periods of heat, sunlight, moisture, and ozone exposure. Because collector vehicles often accumulate miles slowly, sidewall condition, cracking, flat-spotting, and air loss can become more important than tread wear alone.

A good habit is to inspect the tires before every meaningful drive and again after longer storage periods. Clean, dry storage and occasional movement of the truck can help reduce stress on one contact patch over time. Any sign of bulges, deep cracks, cuts, or persistent pressure loss deserves attention before the L320 returns to regular road use.
