1948 Kaiser 482 Tires

The 1948 Kaiser 482 uses a 710-15 tire size. That is a vintage numeric bias-ply size, and it is the primary fitment for this vehicle. The covered 6 Cyl. sub-model uses the same 710-15 sizing, so there is no split fitment to sort through at the sub-model level here.

The practical decision is choosing the right tire within that size rather than deciding between multiple original sizes. Buyers usually compare sidewall style, tire series, and construction approach, especially when deciding whether to keep a period-style bias-ply tire or consider a radial equivalent that should still be checked against wheel width and vehicle clearance.

The 1948 Kaiser 482 uses a 15-inch rim with its primary 710-15 tire size. That rim diameter is part of the tire code itself, with the final number indicating the wheel diameter in inches. Tire selection for this car starts with matching that 15-inch wheel requirement correctly.

Rim diameter is only part of the fitment picture, especially on an older collector car. It still makes sense to confirm the actual wheel on the car, since replacement or aftermarket wheels may have been installed over the years. Wheel width should also be checked before changing tire construction or moving to a radial-equivalent size.

A 710-15 is a numeric bias-ply size. The 710 refers to the tire’s vintage nominal width class, while the 15 designates the wheel diameter in inches. On a 1948 Kaiser 482, it identifies the original sizing format rather than a modern metric or P-metric radial size.

That matters because a vintage numeric bias-ply size should be interpreted within its own era’s sizing system. A modern metric radial may serve as an equivalent, but it is not the same type of size designation. Owners comparing alternatives should verify wheel width, dimensions, and overall appearance before choosing a radial-equivalent setup.

For the 1948 Kaiser 482, 710-15 is the primary bias-ply tire size. That means the original fitment format for this car is a vintage bias-ply construction on a 15-inch rim, matching the kind of tire presentation expected on a late-1940s American passenger car.

Keeping a bias-ply tire usually makes sense when period-style appearance is the main goal. Owners who are considering a radial alternative should treat that as a separate fitment decision rather than assuming the original bias-ply and a radial-equivalent size are automatically interchangeable on the same wheel and vehicle setup.

Radial equivalents for 710-15 include 205R15, P215/75R15, P225/70R15, and 710R15. Those cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial equivalent. Each one is an alternative sizing path away from the original bias-ply construction.

Those choices differ in sizing convention and intended presentation, so the right option depends on the wheel and the look you want from the car. A recommended rim-width range of 6-8 inches is associated with the equivalent radial options. Overall dimensions and clearance should still be checked before any conversion.

Start by confirming the actual wheel diameter and width on the car, then compare the radial-equivalent size you are considering for compatibility. For the 710-15 fitment, radial-equivalent options include 205R15, P215/75R15, P225/70R15, and 710R15. A 6-8 inch rim-width range is associated with those radial alternatives.

Beyond the wheel itself, inspect fender and steering clearance and consider whether the car still has stock suspension and ride height. A collector car that has been modified over the years may not behave like a standard setup. That makes wheel fit, tire dimensions, and clearance checks especially important before changing construction.

Start with the correct 710-15 size and the 15-inch rim requirement, then decide whether the car’s priorities are restoration-oriented appearance, traditional bias-ply construction, or a radial-equivalent alternative. Within the bias-ply choices, the main differences are brand, tire series, sidewall style, and certain product specifications such as rim-width guidance and load figures where stated.

A blackwall tire gives the car a plainer, understated look, while narrow and wide whitewalls create a more dressed-up late-1940s presentation. It also helps to think about how the Kaiser will be used, since occasional show use, touring, and mixed hobby driving can lead buyers toward different construction and appearance priorities.

The 1948 Kaiser 482’s 710-15 tire choices include blackwall, narrow whitewall, and wide whitewall sidewall styles. That gives the car a meaningful appearance range even while staying within the same vintage tire size. Several of the available BFGoodrich, Firestone, Goodyear, and Universal offerings focus on whitewall presentation.

Sidewall choice shapes the car’s visual character more than many buyers expect, especially on a full-size postwar sedan. A wide whitewall usually pushes the look further toward a formal restoration style, while blackwall keeps things simpler. Tire selection should still begin with correct size and wheel compatibility rather than appearance alone.

Available 710-15 tires for the 1948 Kaiser 482 come from BFGoodrich, Firestone, Goodyear, US Royal, and Universal Vintage Tire. Those brands appear across several classic bias-ply product lines, so the brand list is broad enough to give buyers a real comparison within the same basic vintage fitment.

The better way to compare these options is by size correctness, sidewall treatment, tire series, and wheel compatibility rather than assuming one brand is automatically the right choice. For a restoration-focused car, visual presentation may lead the decision. For a driver, construction and setup checks may matter just as much as brand preference.

A period-style 1948 Kaiser 482 usually starts with the original 710-15 numeric bias-ply size. That preserves the vintage sizing format and the traditional tire profile associated with a late-1940s American sedan. From there, the appearance choice often comes down to blackwall, narrow whitewall, or one of several wide whitewall presentations.

For many restorations, the visual effect of the sidewall is almost as important as the construction itself. Buyers seeking the most historically faithful appearance should compare their car against marque references, period photos, or other authoritative restoration sources before choosing a specific whitewall style. That approach is more reliable than assuming every vintage-style option looks the same.

Tire construction changes more than ride feel on a restored 1948 Kaiser 482; it also influences the car’s overall stance and visual character. A 710-15 bias-ply keeps the car in its original sizing language and generally supports a more traditional presentation, especially when paired with the whitewall styles common to the era.

A radial-equivalent setup can still be worth considering, but it should be viewed as an appearance and fitment decision as well as a construction change. Buyers who want the Kaiser to retain a strong late-1940s look often compare a standard radial alternative against a bias-look radial before making that move.

Yes, modifications can affect tire fitment on a 1948 Kaiser 482 even when the tire size itself is correct. Wheel replacements, different wheel widths, altered suspension height, brake conversions, or body changes can all influence how a 710-15 bias-ply tire or a radial-equivalent alternative sits and clears on the car.

Older vehicles often change hands several times, so it is worth confirming what is actually on the car before choosing tires. Checking wheel dimensions, steering travel, and fender clearance is especially important if a radial-equivalent size is being considered, since the original bias-ply fitment does not automatically answer every conversion question.

Before driving a 1948 Kaiser 482 on new tires, inspect the wheels for damage or corrosion, confirm the wheel diameter and width, and make sure each tire is seated properly and inflated appropriately for the setup being used. It is also wise to check valve stems, lug hardware, and basic clearance at full steering lock.

A short collector-car test drive should be treated as a systems check, not just a tire check. Pay attention to vibration, rubbing, unusual steering feel, and any signs of air loss after the first miles. On an older car, suspension wear and steering looseness can also affect how a newly installed tire feels on the road.

Collector-car 710-15 tires should be inspected regularly for visible cracking, bulges, cuts, uneven wear, and signs of air loss. Pressure should be checked routinely, especially on a car that sits for long periods. Even a low-mileage 1948 Kaiser 482 can develop tire issues simply from age, storage conditions, or extended inactivity.

Storage habits matter almost as much as mileage on a hobby vehicle. Keeping the Kaiser away from prolonged sunlight, moisture, and ozone sources can help protect the tires over time. It also makes sense to inspect the tires before longer drives rather than assuming a car that looked fine in the garage is ready for road use.
