1948 Kaiser Tire Fitment Guide

1948 Kaiser vehicles use one tire size across the range covered here: 710-15. That same size fits both the 1948 Kaiser 481 and 1948 Kaiser 482, and the available tires mount on 15-inch wheels. The listed rim-width range for 710-15 is 5.00 to 5.50 inches, which gives you a useful reference when checking original wheels or restored replacements.

That shared fitment simplifies the search because you do not need to sort between multiple tire diameters or rim diameters for these two models. The more important step is confirming that your wheels are true 15-inch Kaiser-spec wheels in the proper width range, then choosing the sidewall style that fits your restoration goals, whether that means a blackwall look or a more formal wide-white presentation.

On a 1948 Kaiser, 710-15 is a traditional numeric bias-ply tire size. The 7.10 portion identifies the nominal section width, while the 15 identifies the wheel diameter in inches. Unlike a modern metric radial size, it does not spell out an aspect ratio, and the bias-ply construction is part of the period-correct design language for a late-1940s American car.

That matters because a 710-15 should be understood as an original-style fitment, not as a modern passenger-car size written in older shorthand. If you are comparing tires for a 1948 Kaiser, decode the size first, then verify wheel diameter and rim width before moving on to sidewall style. That approach avoids mixing era-correct sizing with assumptions drawn from later alphanumeric or metric tire systems.

Yes. The 1948 Kaiser 481 and 1948 Kaiser 482 both use 710-15 tires, so there is no size split between the models covered here. They also share the same 15-inch wheel diameter requirement, which keeps fitment straightforward at the year-and-make level.

That does not mean every tire choice will look the same on every car. A restorer may choose a blackwall for a plainer, understated presentation or a wide whitewall for a more upscale postwar appearance, even though the underlying size remains the same. Once you have confirmed that your car is a 1948 Kaiser and still uses the correct 15-inch wheel setup, the main decision becomes visual character rather than dimensional fit.

1948 Kaiser tires in 710-15 are available in both Blackwall and Wide Whitewall form. BFGoodrich offers blackwall and wide-white versions in this size, while Firestone is also available in blackwall. All of them stay within the correct bias-ply construction for the period, so the visible distinction is primarily the sidewall treatment rather than a change in fitment type.

For a 1948 Kaiser, sidewall style shapes the car’s overall personality more than many buyers expect. Wide whitewalls often suit the formal, optimistic postwar look many owners want on a show-oriented car, while blackwalls can feel more restrained and utilitarian. If authenticity matters for judged events, compare your chosen sidewall look against period photos, club guidance, and the way your particular car was equipped or restored.

BFGoodrich and Firestone both make tires for 1948 Kaiser vehicles in the 710-15 size. The available offerings are all bias-ply tires, and BFGoodrich covers both blackwall and wide-white styling while Firestone appears in blackwall form. That gives Kaiser owners more than one recognized vintage-tire brand within the correct size and construction.

Brand choice on a 1948 Kaiser usually comes down to the visual details you want and how closely you are trying to align the finished car with your restoration plan. Since the size itself does not change between the 481 and 482, buyers can focus on brand heritage, sidewall appearance, and the character each tire brings to the finished stance. It is a more appearance-driven decision than a model-specific fitment decision.

For the 1948 Kaiser, both BFGoodrich and Firestone offer 710-15 bias-ply tires with the same listed maximum load of 1550 pounds at 32 psi and the same 15-inch rim diameter with a 5.00 to 5.50 inch rim-width range. The notable difference is sidewall presentation: BFGoodrich is available in blackwall and wide-white versions, while Firestone is shown in blackwall. Weight also varies slightly among the listed tires, with BFGoodrich versions shown from 21 to 23 pounds and the Firestone at 24 pounds.

That means the practical distinction is not basic fitment but how you want the tire to look on the car and which vintage brand identity best suits your restoration. If you are refining the stance and visual balance of a 1948 Kaiser, the whitewall width options available from BFGoodrich may matter more than the small weight difference. Firestone remains a strong period-style option for owners who prefer a blackwall presentation.

The available 710-15 tires for 1948 Kaiser models are specified for a rim-width range of 5.00 to 5.50 inches. They also mount on a 15-inch wheel, which is the key diameter shared by both the 481 and 482. Staying within that width range helps preserve the intended profile and supports proper seating of an original-style bias-ply tire.

Before fitting tires to a 1948 Kaiser, measure the actual wheel rather than relying on assumptions about what may have been installed during an older restoration. Wheels can be changed over the decades, and a tire that is nominally the correct size can still be mismatched if the rim width is wrong. Confirming width and diameter first is the cleanest way to avoid unnecessary mounting and appearance problems.

The available 710-15 tires for 1948 Kaiser are listed without tube-type or tubeless markings in the size itself, so tube choice should be matched to the tire and wheel combination you are actually using. On a late-1940s car with original-style bias-ply fitment, tube use is often part of the broader wheel-and-tire setup rather than a simple universal rule tied only to the size code.

The important step is to inspect whether your wheels are original-style rims, confirm their condition, and then match the tire setup accordingly. A wheel that has been restored, repaired, or replaced over the life of a 1948 Kaiser may call for a different tube decision than a fully original wheel. If you want to avoid leaks, chafing, or mounting issues, treat tube selection as part of the full wheel package rather than an afterthought.

A 1948 Kaiser should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing sources that can age rubber. Bias-ply tires also benefit from being kept on a clean surface and from periodic movement so the car does not rest in one exact footprint for long stretches. Keeping inflation checked during storage is just as important as the environment itself.

Collector cars often spend more time parked than driven, and that is when many avoidable tire issues begin. If a 1948 Kaiser will sit for an extended period, rolling it occasionally or using storage supports can help reduce flat-spotting and localized stress. Clean, stable storage conditions preserve both sidewall appearance and the more subtle ride qualities that owners expect from an original-style bias-ply tire.

Tires on a 1948 Kaiser should be judged more by age and condition than by mileage, because collector cars often cover limited annual miles. A sound rule is to begin evaluating them closely once they are around five to seven years old and to treat the ten-year mark as a serious replacement consideration, even if tread remains. The DOT date code on the tire is the best way to establish age.

That timeline matters because an older bias-ply tire can look serviceable at a glance while rubber compounds, internal structure, or sidewalls have already begun to age out. For a 1948 Kaiser used mainly for club drives, weekend outings, or shows, replacement decisions should come from calendar age, storage history, and inspection results rather than the low mileage many hobby cars accumulate. Age is usually the deciding factor first.

Tires on a 1948 Kaiser should be inspected before every drive and again before any longer outing. Check for sidewall cracking, tread separation signs, uneven wear, cuts, embedded objects, and pressure loss, and give the valve stems the same level of attention because age-related leaks often begin there. A parked collector car can develop issues quietly between drives, so infrequent use is not a reason to inspect less often.

Regular inspection is one of the easiest ways to keep a 1948 Kaiser enjoyable and predictable on the road. A short local outing may hide a problem that becomes more serious once the car heats up and runs at sustained speed. Building a quick pre-drive routine around pressure, sidewall condition, and visible damage is especially worthwhile on a postwar car that may still use older-style wheels and bias-ply construction.

A 1948 Kaiser 481 would have been associated with bias-ply construction in keeping with normal American passenger-car practice of the period, and the fitment used here is 710-15. That aligns with the late-1940s expectation for a full-size postwar car from an independent maker like Kaiser. Original-equipment brand selection could vary by market, timing, or supply, so the most dependable baseline for authenticity is correct size, correct construction type, and an era-appropriate sidewall style.

For a restoration, that means getting the fundamentals right before chasing finer points. A 710-15 bias-ply tire is the core fitment decision for a 1948 Kaiser 481, while sidewall choice helps shape whether the finished car reads as more formal or more restrained. If your goal is event-level accuracy, compare your tire choice with period photography and seek model-specific guidance from Kaiser marque specialists or club resources.

Correct tire fitment matters on a 1948 Kaiser because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A 710-15 bias-ply tire stays aligned with the period character of the car, while an incorrect size or visibly modern construction can change the stance and visual message of the vehicle. Sidewall treatment also influences authenticity because late-1940s presentation standards were closely tied to how a car sat on its tires.

For show use, the goal is not only that the tire physically fits but that it supports the overall era-correct appearance of the car. Even when two tires share the same basic dimensions, a blackwall and a wide whitewall can convey very different restoration choices on a 1948 Kaiser. Event standards can vary, so buyers pursuing judged competition should compare their selection with marque-club guidance and the expectations of the specific venue.

On a 1948 Kaiser, blackwall and wide whitewall 710-15 tires share the same basic size and bias-ply construction, so the main difference is visual presentation rather than fitment. Blackwalls give the car a plainer, more understated appearance, while wide whitewalls emphasize the formal, upscale late-1940s style that many restorers associate with postwar American cars. Both remain within the correct size family for the year and make.

Choosing between them depends on the story you want the finished car to tell. A wide whitewall can make a 1948 Kaiser look more ceremonial and showroom-oriented, while a blackwall often feels more conservative and practical. If the car is being restored for judged authenticity, period photos and marque guidance are worth consulting, because sidewall style can influence how convincingly the car reflects its original market presence.

1948 Kaiser tires in the available 710-15 fitment are original-style bias-ply tires, and their suitability for highway use depends on proper condition, inflation, age, and matching them to a sound vehicle. The listed products here do not show separate speed-rating letters, so the larger safety picture is centered on correct setup and the condition of the car itself. On a late-1940s automobile, braking, steering, suspension wear, and overall mechanical condition are often just as important as the tire choice.

A well-sorted 1948 Kaiser can be driven confidently within the realistic operating envelope of the car, but it should be approached as a postwar collector vehicle rather than a modern freeway commuter. Bias-ply tires bring the steering feel and road manners expected of the era, which means the driver should leave room, monitor the car closely, and avoid assuming modern handling behavior. Safe highway use starts with honest expectations and thorough preparation.

The available 710-15 tires for 1948 Kaiser models carry a listed maximum load of 1550 pounds at 32 psi. That figure is the tire’s rated load-and-pressure reference, not automatically the day-to-day operating pressure you should use on the car. Factory-recommended inflation for the vehicle should come from the owner’s manual, service literature, or a trusted Kaiser specialist who understands the original application.

The right way to set pressure on a 1948 Kaiser is to begin with the vehicle’s recommended baseline, then verify that it remains appropriate for the specific reproduction tire you are using. Avoid transferring a pressure figure from a different size or from a later radial-equipped vehicle. Correct inflation affects wear, steering feel, and ride quality, and it is one of the easiest adjustments to revisit before any meaningful road use.

Before a longer drive in a 1948 Kaiser, inspect every tire for cracking, bulges, cuts, irregular wear, and pressure loss, and do the same for the spare if you expect to rely on it. Look closely at the valve stems and wheel condition, since age-related issues can appear there before they become obvious in the tread area. A proper tire check should be part of a larger walk-around that also includes brakes, steering response, fluids, and lighting.

Longer trips put sustained heat and load into a tire in a way that short local outings often do not. On a 1948 Kaiser, that makes pre-drive inspection especially worthwhile because the car’s age means several systems interact closely with tire behavior. If anything feels questionable during the check, resolve it before departure rather than treating the drive as a test. A careful half hour in the garage is cheaper than a roadside problem.
