1956 Packard Tire Fitment Guide

1956 Packard vehicles use two tire sizes: 760-15 for the 5640 Series and 5660 Clipper, and 800-15 for the 5680 and 5688 Series. Both are bias-ply sizes and both mount on 15-inch rims. The 760-15 products listed for these cars fit 5.50- to 6.00-inch rim widths, while the 800-15 products listed fit 6.00- to 6.50-inch rim widths.

That means year and make alone are not enough to choose correctly for a 1956 Packard. Start by confirming the series number or model family on the car, then compare the actual wheel width before selecting a tire. The two sizes are close in era and appearance, but they are tied to different model groups and should not be treated as interchangeable without checking the wheel and the car’s intended restoration standard.

On a 1956 Packard, 760-15 is a numeric bias-ply tire size. The 7.60 designation refers to nominal section width in the older numeric system, and the 15 identifies the wheel diameter in inches. It is the correct size family for the 5640 Series and 5660 Clipper models, and available examples include both narrow and wide whitewall versions.

Modern buyers often expect a metric code, but 760-15 belongs to an earlier American sizing convention that was standard on mid-1950s cars. If your Packard falls into the Clipper or 5640-series group, this is the size to research first. Then narrow your choice by sidewall appearance and by confirming the wheel width, especially if the car has been restored or modified at some point in its life.

No, 1956 Packard models do not all use the same tire size. The 5640 Series and 5660 Clipper use 760-15, while the 5680 and 5688 senior Packard series use 800-15. Both are 15-inch bias-ply tires, but the sizes are assigned to different model groups rather than shared across the lineup.

That difference matters because many 1956 Packards look related at a glance, yet the correct tire size follows the series family rather than just the model year. A buyer sorting through a project car, inherited car, or partially restored car should identify the exact model designation before choosing tires. Once the series is confirmed, the size decision becomes much more straightforward.

1956 Packard tires are offered in different whitewall treatments depending on size. In 760-15, available styles include narrow whitewall and wide whitewall versions. In 800-15, the available products are wide whitewall designs, including 3.00-inch and 2.50-inch whitewall variations. All of the listed options remain bias-ply tires, so the visual choice centers on the width of the whitewall rather than a change in construction.

Whitewall width plays a large role in how a 1956 Packard presents, especially on a car restored to period visual standards. A Clipper or 5640-series car gives you more flexibility between subtler and fuller whitewall looks, while the senior-car 800-15 choices stay within the broader whitewall aesthetic associated with upscale mid-1950s American luxury cars. Matching the sidewall style to the car’s trim level and restoration theme usually produces the most convincing result.

Three brands appear in the available 1956 Packard fitments: BFGoodrich, Coker Classic, and Universal Vintage Tire. The 760-15 size is offered across all three brands, while the 800-15 size is represented by Coker Classic. Every listed product for these Packard applications is a bias-ply tire, which keeps the overall character appropriate to the era.

Brand choice on a 1956 Packard usually comes down to the size your model requires first, then the sidewall look you want. Owners of 760-15 cars have the broadest selection, including both narrow and wide whitewall choices from multiple names. Owners of 800-15 senior Packards have a smaller pool, so it makes sense to focus early on whether the whitewall width aligns with the appearance you want for the car.

For 1956 Packard vehicles using 800-15 tires, the main listed difference between the two Coker Classic options is whitewall width: one uses a 2.50-inch whitewall and the other a 3.00-inch whitewall. Both are bias-ply tires, both fit 15-inch rims, both list a 6.00- to 6.50-inch rim-width range, and both carry the same 1800-pound maximum load at 32 psi.

That makes the decision largely visual rather than structural. If you are restoring a senior 1956 Packard and want a fuller mid-1950s luxury appearance, the 3.00-inch whitewall will usually read bolder on the car. If you prefer a slightly more restrained look while staying within a period whitewall theme, the 2.50-inch version gives that option without changing the underlying size or basic fitment.

1956 Packard tires use different rim-width ranges depending on size. The 760-15 tires fitted to 5640 Series and 5660 Clipper models are listed for 5.50- to 6.00-inch rims. The 800-15 tires used on 5680 and 5688 Series cars are listed for 6.00- to 6.50-inch rims. Both sizes share a 15-inch rim diameter, but the approved wheel-width ranges are not the same.

That is why wheel measurement matters before replacing old tires on a 1956 Packard, especially if the wheels may have been swapped over the years. A tire can match the correct rim diameter yet still be wrong for the wheel width. Confirming the actual wheel dimensions before mounting helps preserve the intended stance, tread shape, and overall drivability of a large 1950s Packard.

Original 1956 Packard wheels are not automatically interchangeable between both tire sizes just because both sizes use 15-inch rims. The 760-15 size is paired with a 5.50- to 6.00-inch rim-width range, while 800-15 is paired with a 6.00- to 6.50-inch range. Diameter compatibility is shared, but width compatibility still needs to be verified against the wheels actually on the car.

That matters most on cars that have changed hands, been restored from parts, or mixed Clipper and senior-Packard components over time. If your car still has its original wheels, the model series usually points you in the right direction. If there is any doubt, measure the wheel or have it checked before fitting new tires rather than assuming any 15-inch Packard wheel is suitable for either size.

A 1956 Packard should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, welders, and other ozone sources that accelerate rubber aging. Bias-ply tires also tend to flat-spot more readily during long static storage than modern radials, so keeping the car moving periodically or using stands during extended layups can help reduce shape distortion.

Collector Packards often spend long periods parked, which means storage habits matter almost as much as mileage. Keep the tires inflated, avoid resting the car on damp surfaces, and inspect the sidewalls after winter or long seasonal storage before returning the car to the road. A simple storage routine helps preserve both the look and the service life of vintage-style whitewall tires.

Tires on a 1956 Packard are usually judged by age more than by mileage, because many collector cars see limited seasonal use. A good rule is to begin evaluating them closely around five to seven years of age and to treat about ten years as a serious replacement consideration, even if the tread still looks usable. The DOT date code on the tire is the practical starting point for that timeline.

A low-mileage Packard can still be riding on old rubber that has hardened or cracked with time. Whitewalls may look presentable long after the casing has aged past its most trustworthy period. If the car’s service history is unclear, checking the date code and inspecting for surface cracking, hardening, or irregular wear is more meaningful than relying on tread depth alone.

Tires on a 1956 Packard should be inspected before every drive, and again more carefully before any longer outing or tour. Check for sidewall cracking, cuts, bulges, uneven wear, and pressure loss, and give extra attention to the condition of the whitewall area because age-related deterioration often shows there early. The spare should be inspected on the same schedule rather than ignored.

That inspection routine is especially important on a heavy 1950s luxury car, where a marginal tire can affect steering feel and ride quality before it shows obvious failure. If the car has been sitting, look closely for flat-spotting and for any signs that the tire no longer holds shape evenly. A few minutes of inspection before departure can prevent a ruined day and protect hard-to-replace vintage components.

A 1956 Packard 5640 Series or 5660 Clipper would have been fitted in period with bias-ply tires, and the correct size family here is 760-15. That aligns with how American passenger cars of the mid-1950s were equipped before radial tires became common in the U.S. market. Sidewall appearance could vary by trim, market, and owner preference, so construction and size come first when establishing authenticity.

For a serious restoration, the safest approach is to match the 760-15 size and choose a whitewall style that fits the car’s intended presentation. Buyers chasing strict originality should confirm period sales literature or consult Packard marque clubs for trim-specific guidance, especially on whitewall width. Getting the size and bias-ply construction right is usually the foundation for the rest of the authenticity decision.

Correct tire fitment does matter when showing a 1956 Packard, especially in judged restoration settings. Judges and marque specialists commonly notice whether the tire size suits the model series, whether the construction matches the era, and whether the sidewall treatment looks appropriate for the car’s class and presentation. A senior Packard wearing the wrong size, or a Clipper using a visibly mismatched whitewall treatment, can affect the car’s overall credibility.

Even outside formal judging, the right tire fitment strongly influences how a 1956 Packard sits and reads visually. The car’s proportions were designed around tall bias-ply tires and period sidewall styling, so details that seem small on paper become obvious once mounted. If you plan to show the car, use event rules and Packard club guidance to fine-tune sidewall choice after the correct size has been established.

For 1956 Packard vehicles using 760-15 tires, BFGoodrich and Coker Classic both offer bias-ply options on 15-inch rims with listed 5.50- to 6.00-inch rim-width fitment on their wide-whitewall versions. Both brands list a 1710-pound maximum load at 32 psi on the wide-whitewall examples, while the sidewall styling differs by product, with BFGoodrich offered in both 3.375-inch wide whitewall and 1.00-inch narrow whitewall, and Coker Classic offered in a 3.00-inch wide whitewall.

That means the practical distinction is more about appearance and brand presentation than a dramatic change in basic size class. A buyer restoring a 5640 Series or 5660 Clipper can choose between a fuller or narrower whitewall look while staying in the proper 760-15 bias-ply format. If the car is being prepared for a particular show style, compare the whitewall width carefully against period photos and club references.

1956 Packard tires can be suitable for highway driving when they are the correct size, in sound condition, properly inflated, and used within the normal expectations of a mid-1950s bias-ply tire. The listed 760-15 and 800-15 products here do not show modern speed-letter markings, so they should be approached as vintage-style bias-ply tires rather than as high-speed modern performance tires. On a 1956 Packard, the car’s age, weight, braking capability, and suspension condition are often just as important as the tire itself.

For practical driving, that means keeping speeds sensible, allowing extra following distance, and making sure the chassis is sorted before asking much of the tires. A freshly restored or seldom-driven Packard should be road-tested progressively rather than sent straight onto an interstate after years of inactivity. Safe highway use starts with condition, correct fitment, and realistic expectations about how a large 1956 car behaves.

The listed load figures for 1956 Packard tires show 760-15 examples rated at 1710 pounds at 32 psi and 800-15 examples rated at 1800 pounds at 32 psi on the products where load data is given. Those figures describe the tire’s rated load-and-pressure relationship, not necessarily the exact operating pressure your specific Packard should run in every condition. Factory guidance from the owner’s manual remains the right reference for vehicle-specific pressure targets.

Use the tire maker’s ratings and the Packard factory recommendation together rather than transferring one pressure assumption across both sizes. A 760-15 Clipper-family car and an 800-15 senior Packard do not share the same tire size, so pressure habits should not be copied casually from one to the other. After inflation, recheck pressure when the tires are cold and monitor wear patterns over time.

Before taking a 1956 Packard on a longer drive, inspect all four tires and the spare for cracking, cuts, bulges, irregular wear, and proper cold inflation. Pay close attention to sidewall condition on older whitewalls, and verify that the tires are the correct 760-15 or 800-15 size for the car’s model series. Tire condition should be part of a broader pre-drive check that also includes brakes, steering, cooling, and fluid levels.

A long-distance outing in a 1956 Packard is most enjoyable when the car is treated like the vintage machine it is rather than like a modern commuter. Bring the tire inspection into the same routine as checking belts, hoses, wheel hardware, and the spare’s accessibility. If the car has been sitting, a short local shakedown run before the main trip is a smart way to catch vibration, pull, or pressure issues early.
