1952 Buick Tire Fitment Guide

1952 Buick vehicles use two tire sizes, depending on model. The 1952 Buick 40 Special and 1952 Buick 50 Super use 760-15 bias-ply tires, while the 1952 Buick 70 Roadmaster uses 800-15 bias-ply tires. Both sizes mount on 15-inch rims. For 760-15, listed rim widths run from 5.50 to 6.00 inches, and for 800-15, listed rim widths run from 6.00 to 6.50 inches.

That means a buyer should identify the exact Buick model before going any further, because the correct size follows the series. A Special or Super should be matched to 760-15, while a Roadmaster should stay with 800-15. Even though both sizes share the same rim diameter, the wheel width range is different enough that it is worth checking the actual wheel before choosing a specific tire.

On a 1952 Buick, 760-15 is a numeric bias-ply size. The 7.60 refers to the tire’s nominal section width in inches, and the 15 refers to the wheel diameter in inches. On 1952 Buick models, that size applies to the 40 Special and 50 Super. Available versions include narrow whitewall and wide whitewall styles from more than one brand.

That size code helps separate the mid-series Buicks from the larger Roadmaster, which uses 800-15 instead. If your car is a Special or Super, 760-15 is the right place to start, and the next choice is usually sidewall appearance rather than a change in basic fitment. Owners aiming for a very era-authentic look often compare the whitewall width against factory photos, surviving originals, or marque-club guidance.

No, 1952 Buick models do not all use the same tire size. The 40 Special and 50 Super share 760-15 tires, but the 70 Roadmaster uses 800-15. All of them use bias-ply construction and 15-inch rim diameter, yet the Roadmaster moves to a larger numeric size and a wider recommended rim-width range.

That split matters because a year-and-make search alone can lead you to more than one valid Buick size. If you are working from an older title, inherited car, or partially restored project, verify whether the car is a Special, Super, or Roadmaster before selecting tires. Buick’s model hierarchy in 1952 is reflected directly in the tire sizing, so getting the series right is the first fitment checkpoint.

1952 Buick tires are available with more than one sidewall treatment, depending on size. In 760-15, current offerings include narrow whitewall and wide whitewall versions. In 800-15 for the Roadmaster, available products are wide whitewall styles with different whitewall widths. All listed choices are bias-ply tires, so the visible difference is primarily the whitewall presentation rather than a change in construction.

That gives owners room to match the tire to the character of the car and the tone of the restoration. A broad whitewall generally suits the formal postwar Buick look most buyers expect, especially on higher-trim cars, while a narrower whitewall can create a more restrained appearance on a driver-quality Special or Super. For strict show work, compare whitewall width and profile against period Buick literature or event-specific judging standards.

1952 Buick tires are available from several brands, but the selection depends on size. The 760-15 size for the 40 Special and 50 Super is offered by BFGoodrich, Coker Classic, and Universal Vintage Tire. The 800-15 size for the 70 Roadmaster is offered in the current selection by Coker Classic. Every listed option is a bias-ply tire sized for 15-inch Buick applications.

Brand choice is easiest on the Special and Super because that size has the broader mix of sidewall presentations. Roadmaster owners have a narrower brand range in the current 800-15 selection, so the decision tends to center on whitewall appearance within the correct size rather than on switching between multiple constructions. If visual authenticity matters most, compare each brand’s sidewall treatment with the look you want the finished Buick to present.

The current 800-15 choices for 1952 Buick vehicles are both Coker Classic bias-ply tires for the 70 Roadmaster, and both carry the same listed 1800-pound maximum load at 32 psi, the same 15-inch rim diameter, the same 6.00 to 6.50-inch rim-width range, and the same 26-pound weight. The visible difference is the whitewall treatment: one uses a 3.00-inch whitewall and the other uses a 2.50-inch whitewall.

That means the decision is largely cosmetic rather than structural. Owners trying to capture a broader early-1950s luxury-car look may prefer the fuller whitewall, while others may want the slightly narrower band for a subtler presentation. Since the fitment specifications are otherwise aligned, the practical question becomes which whitewall width best matches your Roadmaster’s restoration style, wheel covers, and overall visual balance.

1952 Buick tire rim-width requirements depend on the size. For 760-15 tires used on the 40 Special and 50 Super, listed rim widths run from 5.50 to 6.00 inches. For 800-15 tires used on the 70 Roadmaster, listed rim widths run from 6.00 to 6.50 inches. Both sizes are built for 15-inch rim diameter, but they are not intended for the same width range.

That is why wheel inspection matters even when the car already has 15-inch rims on it. A car that has had wheels swapped during decades of service may no longer be carrying the right width for its intended tire size. Before mounting new tires, check the wheel itself, compare it with the correct size range, and make sure the chosen tire and wheel combination lines up with the Buick model you are restoring or driving.

The current 1952 Buick tire listings do not carry tube-type or tubeless markings in the size designation, so tube fitment should be confirmed against the specific tire and wheel being used. Every listed tire is a bias-ply design for a 15-inch application, and tube decisions on collector cars often depend on both the tire’s construction details and the wheel’s design and condition.

That makes the wheel just as important as the tire when planning the installation. Original-style steel wheels, older rims with surface wear, or restoration work that prioritizes period-correct setup often lead owners to verify tube use carefully before mounting. Instead of assuming all 1952 Buick tires are handled the same way, match the tire choice to the actual wheel and confirm the setup before final assembly.

Original 1952 Buick wheels can only be shared across both tire sizes if the wheel has the correct 15-inch diameter and also falls within the proper width range for the tire being considered. The 760-15 size uses 5.50 to 6.00-inch rims, while the 800-15 size uses 6.00 to 6.50-inch rims. The overlap exists at 6.00 inches, but the rest of the width range is not identical.

That means some 15-inch Buick wheels may cross over, but it should never be assumed simply because the bead diameter matches. If a Roadmaster wheel has been fitted to a Special, or vice versa, the tire choice may need to be reconsidered along with the wheel. Measure or verify the wheel first, then confirm that the tire size for your Buick model also matches the wheel width you actually have.

A stored 1952 Buick should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can accelerate sidewall aging. Because 1952 Buick tires here are bias-ply designs, they are more prone to temporary flat-spotting after long stationary periods than a radial would be. Clean floors, stable temperature, and proper inflation help reduce stress on the casing during storage.

Owners who leave the car parked for extended periods should roll it occasionally to change the tire contact patch or support the car in a way that avoids long-term concentrated loading if the storage plan allows it. The goal is to protect both the rubber and the shape of the tire. A collector Buick that looks excellent in the garage can still develop avoidable tire issues if it sits in heat, sun, or ozone-heavy conditions.

Tires on a 1952 Buick should be judged more by age and condition than by mileage, because collector cars often see limited annual use. A good rule is to begin evaluating them carefully once they reach the five- to seven-year range and to treat around ten years as a serious replacement point regardless of tread depth. The DOT date code on the tire helps establish age, even if the car has been driven only occasionally.

That approach matters because rubber hardens, cracks, and loses resilience over time even when a Buick is not accumulating many miles. A tire can look presentable from a few feet away and still be aging out structurally. If the car has an older spare, include it in the same age check so you are not relying on a vintage-looking but over-aged backup tire when taking the car on tours or regional events.

Tires on a 1952 Buick should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, bulges, irregular tread wear, and signs that the tire is losing pressure between uses. Since many collector cars spend long periods parked, a quick visual check before moving the car is more important than owners sometimes realize.

A longer pre-trip inspection should also include valve stems, wheel condition, and the spare tire so the whole package is ready for the road. Bias-ply tires can telegraph alignment or suspension issues in wear patterns differently than modern radials, so unusual wear should prompt a closer chassis review rather than just another air-pressure adjustment. Frequent inspection is one of the simplest ways to keep a seldom-driven Buick dependable and predictable.

A 1952 Buick 40 Special would have been fitted in the bias-ply era, and the correct size for that model is 760-15. That aligns with the broader industry standard of the early 1950s, when bias-ply construction was still the norm for American passenger cars. While multiple modern reproduction brands exist in that size, original-equipment brand choice should be verified by market-specific literature or Buick marque resources if absolute factory detail matters.

For most restorations, getting the size, construction type, and sidewall appearance right has more visual and judging impact than chasing an assumed original brand name. A Special restored as a stock 1952 Buick should stay with a 760-15 bias-ply format and then refine the look through whitewall style. If your car is unusually original or tied to a high-level show standard, period brochures and Buick club references are the right next step.

Correct tire fitment does matter when showing a 1952 Buick, especially in judged restoration settings. Size, construction, and sidewall appearance all affect whether the car looks appropriate for its year and series. On a 1952 Buick, using 760-15 on a Special or Super and 800-15 on a Roadmaster preserves the model-correct proportions, while staying with bias-ply construction matches the period character expected of the era.

What gets noticed at shows is often not just whether the tire fits the wheel, but whether it fits the story of the car. A whitewall width that feels too modern or a model wearing the wrong series size can stand out to experienced judges and marque enthusiasts. For event-specific standards, consult the organizing body or Buick club guidance, because some judging systems are stricter than others about sidewall detail and restoration accuracy.

Available 760-15 tires for the 1952 Buick 40 Special and 50 Super differ mainly in brand and sidewall style rather than in basic size. Current choices include BFGoodrich, Coker Classic, and Universal Vintage Tire, all in bias-ply construction. Sidewall treatments include a 1.00-inch narrow whitewall and wider whitewall versions such as 3.00-inch and 3.375-inch styles. Where load figures are listed, 1710 pounds at 32 psi appears on the BFGoodrich and Coker Classic wide-whitewall examples.

That makes 760-15 selection as much a visual restoration decision as a fitment one. A narrower whitewall can suit a subtler presentation, while the larger whitewall options create a stronger early-1950s Buick look. Because the Special and Super share the same base size, owners can focus on the finish they want the tire to bring to the car without changing away from the correct 760-15 format.

1952 Buick tires can be suitable for highway use when they are in good condition, correctly fitted, and inflated appropriately, but they are bias-ply tires and should be driven with the expectations that come with period construction. No speed ratings are shown in the available size markings here, so the practical limit is not something to assume from modern passenger-car habits. On a 1952 Buick, overall roadworthiness also depends heavily on the car’s brakes, steering, suspension, and wheel condition.

That means highway use should be approached as part of the whole vehicle, not just as a tire question. A properly sorted Buick can cruise comfortably within the pace its design supports, but the driver should still respect the feel and response of a 1950s full-size car on bias-ply tires. If the car wanders, shakes, or reacts oddly at speed, address the chassis and wheel setup before treating it as a normal modern highway cruiser.

Available load-and-pressure figures for 1952 Buick tires differ by size and should not be transferred from one application to another. In 760-15, listed wide-whitewall examples show 1710 pounds at 32 psi. In 800-15, listed examples show 1800 pounds at 32 psi. Those figures describe the tire’s rated load at that pressure, not automatically the factory operating recommendation for every Buick model and driving condition.

The right approach is to start with the original Buick owner guidance for the car and then compare it with the tire manufacturer’s specifications for the exact reproduction tire being used. A Special or Super on 760-15 should be evaluated within that size’s ratings, while a Roadmaster on 800-15 should be evaluated within its own. Keeping pressures matched to the specific tire and vehicle helps preserve handling balance, wear pattern, and ride quality.

Before a longer drive in a 1952 Buick, inspect each tire for cracking, cuts, bulges, embedded debris, and uneven wear, then confirm pressures when the tires are cold. Check the spare as well, because a touring plan is only as good as the backup tire in the trunk. Since these are vintage-style bias-ply applications, it is also wise to look closely at wheel condition and make sure the tires have been mounted on the correct rim width for the size.

A good tire inspection should be part of a larger mechanical once-over that includes brakes, steering, cooling, and lighting, because any one of those systems can end a trip faster than tread depth will. Longer drives reveal small problems that local errands may hide. If the Buick has been sitting, give it a short local test run first so you can feel for pull, vibration, or pressure loss before committing to highway time.
