Chevrolet entered 1956 as one of the defining names in the American market, offering everything from practical family transportation to the image-driven Corvette sports car. That broad lineup makes tire selection worth understanding, because 1956 Chevrolet covered three model groups here while keeping them on one shared size: 670-15 bias-ply. The real choice is less about model-to-model fitment and more about how you want the car to present, from blackwall simplicity to wide whitewall styling that suits a period-correct restoration. Before choosing a tire, confirm your exact model and decide whether appearance, authenticity, or general collector-car use matters most for your Chevrolet.
Which Tire Size Is Right for Your 1956 Chevrolet
Only one tire size appears across 1956 Chevrolet vehicles here, and it is shared by every listed model. That means the main decision is not between different fitment sizes, but between bias-ply product choices, sidewall appearance, and the wheel width range that best matches your car. Understanding that distinction before choosing a product saves time and helps match the tire to the way your Chevrolet will be used and presented.
Year(s): 1956|Fit(s): 1956 Chevrolet, Corvette, Wagon|Construction: Bias Ply|Rim: 15 in
670-15 is a numeric bias-ply size in which 6.70 is the nominal section width and 15 is the wheel diameter in inches. Brands in this size include Firestone, US Royal, Coker Classic, and Universal Vintage Tire, with blackwall and wide whitewall sidewall styles available; listed products carry load ratings such as 1450 pounds at 32 psi and 1550 pounds at 32 psi. This is the year-wide size for the listed 1956 Chevrolet models, so the practical choice comes down to the look you want and whether you are aiming for a straightforward driver presentation or a more era-correct restoration appearance.
Three 1956 Chevrolet model groups are covered here. All of them use the same 670-15 tire size, so fitment does not change from model to model, but the right product choice can still vary depending on whether you are restoring a family hauler, a mainstream passenger car, or a halo sports car.

1956 Chevrolet
The core 1956 Chevrolet passenger-car line represents the heart of Chevrolet's mid-Fifties appeal, with styling and everyday usability that helped define the brand's place in postwar America. Its tires mount on 15-inch wheels, and the shared 670-15 sizing leaves room to choose a blackwall or wide whitewall presentation depending on how original or understated you want the car to look.
The 1956 Chevrolet Corvette marked an important step in the early evolution of America's sports car, with cleaner styling and a more confident performance image than the first-year cars. Its tires also mount on 15-inch wheels, and the same 670-15 size used elsewhere in the Chevrolet lineup supports a traditional bias-ply look that suits an authentic mid-Fifties presentation.
The 1956 Chevrolet Wagon reflects the era when station wagons were becoming a central part of American family life, blending passenger-car style with added utility. It uses the same 15-inch wheel diameter as the other listed 1956 Chevrolet models, so the 670-15 choice is shared even though a wagon owner may prioritize durability, stance, or a family-car-correct sidewall look differently.
Twenty-seven products are available across one tire size for 1956 Chevrolet vehicles. In 670-15, Firestone, US Royal, Coker Classic, and Universal Vintage Tire offer bias-ply choices in blackwall and wide whitewall styles, so confirm your preferred look and wheel-width match before selecting.
These FAQs cover the shared 670-15 sizing used across 1956 Chevrolet models, the differences between blackwall and wide whitewall product choices, setup details like wheel width, and the care vintage bias-ply tires need on collector cars.
Size Basics & Fitment
What tire sizes fit 1956 Chevrolet vehicles?
1956 Chevrolet vehicles covered here use one tire size: 670-15. That same size applies to the listed Chevrolet passenger car, Corvette, and Wagon models, and it mounts on a 15-inch rim. Available products show rim width ranges of 4.50 to 5.00 inches for some versions and 5.00 to 6.00 inches for others, so the wheel width should be checked against the specific tire you are considering.
That shared sizing simplifies the search because you do not need to sort through multiple diameters for these models. The more important step is confirming which 670-15 product matches your actual wheel and the look you want, especially if you are deciding between blackwall and wide whitewall options for a restoration or a regularly driven collector car.
What does 670-15 mean on a 1956 Chevrolet tire?
A 670-15 marking on a 1956 Chevrolet tire is a numeric bias-ply size. The 6.70 portion is the nominal section width expressed in the period style, and the 15 identifies the wheel diameter in inches. Unlike a modern metric radial size, it does not include an aspect ratio or an "R" to identify radial construction, because this is a traditional bias-ply format from the era.
Understanding that older size code helps keep a 1956 Chevrolet in the right historical lane. When you compare products, focus on the sidewall style, brand character, rated wheel-width range, and load figure shown for that specific 670-15 tire rather than trying to translate it directly into a modern passenger-car size without checking the intended application.
Do all 1956 Chevrolet models use the same tire size?
The listed 1956 Chevrolet models here all use the same 670-15 tire size. That includes the core Chevrolet passenger-car line, the Corvette, and the Wagon, all on 15-inch rims. Fitment therefore stays consistent at the year-and-make level even though the vehicles themselves serve very different roles, from family transportation to early American sports-car duty.
Shared size does not mean every owner should make the same product choice. A Corvette owner may lean toward a presentation that suits a sports car shown with period flavor, while a wagon owner may care more about a clean, durable driver look. The model matters more for appearance and restoration intent than for basic tire size in this case.
Buying the Right Tire
What sidewall styles are available for 1956 Chevrolet tires?
1956 Chevrolet tires in 670-15 are available in blackwall and wide whitewall styles. Firestone and Universal Vintage Tire appear in blackwall form, while US Royal and Coker Classic appear in wide whitewall form. Both are bias-ply constructions, so the visible difference is primarily about presentation and period appearance rather than changing the fundamental size or wheel diameter.
That choice matters because sidewall style strongly affects how a mid-Fifties Chevrolet reads visually. Wide whitewalls are closely associated with the era's mainstream American styling and are often favored on restored show cars, while blackwalls can suit a plainer or more understated look. Matching the tire's appearance to the car's finish and restoration goal usually produces a better result than choosing on size alone.
What brands make tires for 1956 Chevrolet vehicles?
1956 Chevrolet vehicles in 670-15 have choices from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. All of them offer bias-ply construction in the correct 15-inch fitment, but the visible presentation varies by product because some are blackwalls and others are wide whitewalls. Load ratings also vary, with listed examples including 1450 pounds at 32 psi and 1550 pounds at 32 psi.
Brand choice on a 1956 Chevrolet is often tied to the style of restoration you want to achieve. Some owners prefer a brand with strong period recognition, while others focus on finding the right sidewall treatment and wheel-width compatibility. Narrowing the field by appearance first, then confirming the exact tire's fit on your wheel, is usually the clearest path.
What is the difference between Firestone and Coker Classic tires for the 1956 Chevrolet?
Firestone and Coker Classic both offer 670-15 bias-ply tires for the 1956 Chevrolet, but they differ in presentation and wheel-width range. The listed Firestone version is a blackwall with a 4.50-to-5.00-inch rim width range and a 1450-pound load rating at 32 psi, while the listed Coker Classic version is a 2.75-inch wide whitewall with a 5.00-to-6.00-inch rim width range and a 1550-pound load rating at 32 psi.
That makes the comparison less about one being universally preferable and more about matching the product to your car. Firestone suits an owner after a simpler blackwall look on a narrower wheel, while Coker Classic suits someone wanting a prominent whitewall and a tire intended for a wider wheel range. Wheel measurement should come before appearance if your car's rims are not known.
Fitting & Setup
What rim width do 1956 Chevrolet tires require?
1956 Chevrolet tires in 670-15 mount on 15-inch rims, but the acceptable rim width depends on the specific tire. Listed products in this size show ranges of 4.50 to 5.00 inches on some applications and 5.00 to 6.00 inches on others. The diameter stays the same across the size, yet the wheel-width requirement can change by brand and sidewall version.
That detail matters because a tire can be the right nominal size and still be a poor match for the wheel if the rim is too narrow or too wide for that specific product. Measure the actual wheel or confirm its width before final selection, especially on older cars that may have had wheel swaps during decades of ownership and restoration.
Do 1956 Chevrolet tires require inner tubes?
The listed 670-15 products for 1956 Chevrolet do not carry tube-type or tubeless markings in the size field, so tube use should be confirmed against the exact tire and the wheel it will be mounted on. With vintage bias-ply applications, the wheel's original design and condition can be just as important as the tire itself when deciding whether tube use is appropriate.
A careful setup check is worthwhile on any 1956 Chevrolet because decades-old wheels may have been restored, repaired, or replaced. If your car retains original-style rims, inspect the wheel well, valve-stem arrangement, and sealing surfaces before mounting tires, and verify the recommendation for the specific product you choose rather than assuming every 670-15 is configured the same way.
Maintenance, Storage & Longevity
How should I store a 1956 Chevrolet when the tires are fitted?
A 1956 Chevrolet should be stored away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age rubber. Keep the floor dry, maintain proper inflation, and move the car periodically if possible. Bias-ply tires are more prone to developing temporary flat-spotting during long static storage than a modern radial, especially in cooler temperatures.
Owners who store a 1956 Chevrolet for long stretches often benefit from short monthly roll-outs or from supporting the vehicle in a way that reduces constant loading on one contact patch. Clean, stable storage conditions do more to preserve sidewalls and ride quality than occasional cosmetic dressing, particularly on wide whitewall tires that are purchased as much for appearance as function.
How long do tires on a 1956 Chevrolet typically last?
Tires on a 1956 Chevrolet should be judged more by age and condition than by miles driven. A collector-car tire often sees light use, so many owners begin evaluating closely once the tire is around five to seven years old and consider replacement as it approaches ten years, even if tread remains. The DOT date code and the tire's physical condition are more meaningful than odometer use alone.
That approach is especially sensible on a vintage Chevrolet because stored cars can look fine while the rubber slowly hardens or cracks with time. Sidewall checking, vibration, persistent air loss, and visible aging around the bead or tread blocks are all signals to move from occasional inspection to replacement planning before a longer driving season begins.
How often should tires on a 1956 Chevrolet be inspected?
Tires on a 1956 Chevrolet deserve a quick inspection before every drive and a more careful check before any extended outing. Look for sidewall cracking, tread separation, cuts, embedded debris, bulges, uneven wear, and loss of air pressure. On an older bias-ply setup, it is also smart to inspect valve stems and the spare so the entire road set is ready if the car is used away from home.
Frequent inspection matters because collector cars often sit longer than modern daily drivers, and problems can develop between outings instead of through steady use. A few minutes in the garage can catch age-related damage, wheel-seal issues, or a slow leak before it turns into a roadside problem. That habit is one of the simplest ways to make a 1956 Chevrolet more enjoyable to drive.
Restoration & Authenticity
What tires were originally fitted to the 1956 Chevrolet Corvette?
A 1956 Chevrolet Corvette from this era would have been fitted with bias-ply tires, and the listed size used across the covered 1956 Chevrolet models is 670-15. That aligns with normal mid-Fifties American practice, when bias-ply construction was standard and radial fitments were not part of mainstream U.S. production-car tire selection. Sidewall appearance could vary by market presentation and owner preference, but the construction type belongs squarely to the period.
For a restoration, that means the key authenticity points are the 670-15 size, bias-ply construction, and a sidewall treatment that suits the way your Corvette is being presented. If the car is intended for judged competition, confirm event-specific standards with Corvette specialists or marque clubs, since details such as whitewall width and finish expectations can differ by judging body and restoration philosophy.
Does correct tire fitment matter for showing a 1956 Chevrolet?
Correct tire fitment matters on a shown 1956 Chevrolet because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A 670-15 bias-ply tire is consistent with the period represented here, while an obviously modern construction or a sidewall treatment that clashes with the car's restoration theme can stand out even if the tire physically fits the wheel.
The practical question is how the car will be judged and by whom. A local driver-quality show may reward overall presentation, while a marque-focused event may care more about whether the tire's construction and visual details match accepted period practice. Deciding that standard before buying tires helps avoid paying twice for a set that looks right in the garage but wrong on the show field.
What is the difference between US Royal and Firestone tires for the 1956 Chevrolet?
US Royal and Firestone both offer 670-15 bias-ply tires for the 1956 Chevrolet, but their listed presentations differ. The Firestone example is a blackwall with a 1450-pound load rating at 32 psi and a 4.50-to-5.00-inch rim width range, while the US Royal example is a 2 11/16-inch wide whitewall with the same 1450-pound load rating at 32 psi and the same 4.50-to-5.00-inch rim width range.
That means the choice between them is largely visual rather than dimensional within the listed specifications. A Firestone blackwall can support a simpler, more restrained appearance, while the US Royal wide whitewall places the car more firmly in a classic mid-Fifties American presentation. On a show-oriented Chevrolet, that sidewall difference can influence the car's overall authenticity almost as much as the size itself.
Safety & Road Use
Are 1956 Chevrolet tires safe for highway driving?
A properly maintained 670-15 bias-ply tire can be used for normal highway driving on a 1956 Chevrolet when it is in good condition, correctly mounted, and inflated appropriately for the vehicle and load. Bias-ply construction has a different road feel than a modern radial, with more sensitivity to road crown and a generally more period-correct driving character. On a mid-Fifties car, overall mechanical condition often matters just as much as the tire itself.
Safe road use starts with realistic expectations. A 1956 Chevrolet, whether passenger car, wagon, or Corvette, should be driven within the limits of its brakes, steering, suspension, and age, not simply up to whatever traffic around it is doing. Fresh inspection, stable pressure, and sound wheel condition are better predictors of confidence on the highway than the fact that the tire is new alone.
What inflation pressure should I use for 1956 Chevrolet tires?
Listed 670-15 products for 1956 Chevrolet include load-and-pressure figures such as 1450 pounds at 32 psi and 1550 pounds at 32 psi. Those numbers describe the tire's rated capacity at that pressure, not automatically the exact pressure every 1956 Chevrolet should run in service. Factory recommendations belong to the vehicle, while the tire's stated rating belongs to the product itself.
Use the original owner's manual or marque-standard guidance for the vehicle's starting pressure recommendation, then confirm that the tire you choose is being used within its published limit. Avoid carrying a pressure figure from one brand or one product version to another just because the size is the same, since sidewall style and wheel-width range can differ across 670-15 offerings.
What should I check before taking a 1956 Chevrolet on a longer drive?
Before taking a 1956 Chevrolet on a longer drive, inspect each tire for cracking, cuts, bulges, irregular wear, and stable pressure, and do not forget the spare. Check the valve stems, confirm the wheels are in good condition, and look over the sidewalls carefully if the car has been sitting. Tire readiness should be part of a broader inspection that also includes brakes, steering, cooling, and fluid levels on a car of this age.
That extra attention matters because long drives expose small garage-only issues that never show up on a quick neighborhood outing. A sound 670-15 bias-ply setup can serve well, but only if the tires and wheels are as ready as the rest of the car. Spending a little time before departure is far easier than diagnosing a vibration, leak, or heat-related problem after the trip has already begun.
