1951 Ford Tire Fitment Guide

1951 Ford vehicles covered here use two different tire sizes, and the fitment depends on model. The 1951 Ford Custom uses 670-15 bias-ply tires on 15-inch rims, while the 1951 Ford DL uses 600-16 bias-ply tires on 16-inch rims. For 670-15 products, listed rim widths include 4.50 to 5.00 inches and 5.00 to 6.00 inches depending on the tire. For 600-16 products, listed rim widths include 4.00 to 4.50 inches.

That means year and make alone are not enough to select a tire for a 1951 Ford. Start by identifying whether your car is a Custom or a DL, then confirm the wheel diameter actually on the car before narrowing your choice by brand or sidewall style. Cars that have been restored, modified, or swapped over the years may no longer carry their original wheels, so a quick wheel check prevents choosing a 15-inch tire for a 16-inch application or the reverse.

On a 1951 Ford, 670-15 is a numeric bias-ply tire size. The 6.70 portion refers to the nominal section width in inches, and the 15 identifies the wheel diameter in inches. In this year-make range, 670-15 applies to the Ford Custom and is offered in both blackwall and wide whitewall styles from several vintage-focused brands.

That code matters because it reflects a traditional mid-century sizing system rather than a modern metric one. If your 1951 Ford Custom is being restored to a period appearance, 670-15 keeps you in the right visual and construction family for the era. It is still smart to compare the specific tire's approved rim-width range before making a final selection, especially if the car has aftermarket wheels or wheels sourced from another Ford application.

No, 1951 Ford models do not all use the same tire size. The Custom uses 670-15, while the DL uses 600-16. Both are bias-ply sizes appropriate to the period, but they are not interchangeable because they mount on different rim diameters and serve different model applications within the 1951 Ford lineup.

That split is the most important fitment detail on this page. If you are unsure which model you have, the wheel diameter on the car can help point you in the right direction, but model identification should still come first. Once the model is confirmed, the next decision becomes appearance and brand preference rather than choosing between multiple constructions for the same fitment.

1951 Ford tires are available in both blackwall and wide whitewall styles, but the choices vary by size. The 670-15 size for the Custom includes blackwall and wide whitewall offerings, and the 600-16 size for the DL also appears in both blackwall and wide whitewall form. That gives owners of either model a period-appropriate visual range rather than forcing one look across the whole year and make.

Sidewall style has a strong effect on how a 1951 Ford presents, especially on an early-1950s body where tire appearance is a visible part of the car's stance. Blackwalls generally suit plainer or more understated presentations, while wide whitewalls align with the upscale styling cues many restorers want from the period. Match the sidewall treatment to the way your car is being restored and shown, then confirm the exact size and wheel diameter before choosing a specific tire.

Several brands cover 1951 Ford applications, and the lineup changes by size. The 670-15 Custom fitment is available from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. The 600-16 DL fitment is available from BFGoodrich, Coker Classic, Avon, and Firestone. Across both sizes, the brand selection stays rooted in vintage-style reproduction and heritage-pattern offerings rather than modern high-volume passenger-car tires.

Brand choice on a 1951 Ford often comes down to the look you want and the exact product style available in your size. Some owners prioritize a historically familiar name on the sidewall, while others focus first on whether the tire is offered as a blackwall or wide whitewall. Once the model and size are settled, compare the brand options within that size rather than assuming every brand appears in both Ford fitments.

On a 1951 Ford, Firestone and Coker Classic overlap in both listed sizes, but the details differ by product. In 670-15, the Firestone blackwall is listed with a 1450-pound load capacity at 32 psi and a 4.50 to 5.00-inch rim-width range, while one Coker Classic wide whitewall in the same size is listed at 1550 pounds at 32 psi with a 5.00 to 6.00-inch rim-width range. In 600-16, both Firestone and Coker Classic examples are listed at 1400 pounds at 32 psi with 4.00 to 4.50-inch rim-width guidance, though they differ in sidewall style and weight.

That means the practical difference is not just brand name. On a 1951 Ford, the exact tire you choose can change the sidewall appearance and the approved wheel-width range even within the same nominal size. Compare the individual tire's rim-width guidance and visual treatment to your wheel and restoration goals instead of assuming every 670-15 or 600-16 is identical across all brands.

Rim-width guidance for 1951 Ford tires depends on the size and the specific tire. For 670-15 tires used on the Custom, listed rim widths include 4.50 to 5.00 inches on some products and 5.00 to 6.00 inches on others. For 600-16 tires used on the DL, listed products show a 4.00 to 4.50-inch rim-width range. Those figures are tied to the individual tire, not automatically to every product carrying that nominal size.

The main takeaway is to match the tire to the actual wheel rather than relying on size code alone. Two 670-15 tires can look similar but be approved for slightly different wheel widths, which matters for fit, profile, and how the tire sits on the rim. Measure the wheel or verify the wheel specification before finalizing a tire choice, especially if the car has replacement steel wheels or older restorations of uncertain origin.

The available 1951 Ford products do not all carry a tube-type or tubeless marker in the size wording, so tube requirement should be treated as product-specific rather than assumed across the whole year and make. Both 670-15 and 600-16 are vintage bias-ply fitments, and whether a given tire is run with a tube can depend on the tire's construction details and the wheel itself. Older original-style wheels often influence that decision just as much as the tire size does.

The safest approach is to confirm the sidewall marking and match that to the wheel you are actually using. A tube-compatible wheel and tire combination may call for different setup parts than a tubeless-capable one, and valve-stem condition becomes especially important on collector cars that sit for long periods. Check the specific tire before installation rather than applying one blanket rule to every 1951 Ford product.

A stored 1951 Ford should be kept away from direct sunlight, standing moisture, and ozone sources such as electric motors, battery chargers, compressors, and furnaces. Clean, dry storage helps preserve the rubber and the sidewall finish, whether the car wears blackwalls or wide whitewalls. Because both listed 1951 Ford fitments are bias-ply, long static storage can encourage temporary flat-spotting more readily than many later radials.

If the car will sit for extended periods, maintain proper inflation and move it periodically so the same section of tread is not carrying the load month after month. Some owners also use stands to reduce weight on the tires during long-term storage, but they should still keep the suspension and chassis supported correctly. A breathable cover and a cool, stable environment do more for tire longevity than occasional cosmetic cleaning.

On a 1951 Ford, tire life is usually governed more by age than mileage. Collector vehicles often accumulate very few miles, so a tire can still have substantial tread while the rubber has already aged. A good rule is to begin closer evaluation in the five- to seven-year range and to treat around ten years as a serious replacement consideration, with the DOT date code used to establish the tire's age.

That matters especially on an older Ford that sees occasional local driving, show use, or long periods in storage between outings. Sidewall cracking, hardening, recurring air loss, and visible weathering are more meaningful warning signs than tread depth alone on a low-use classic. Even a carefully stored tire deserves age-based scrutiny before road use simply because time affects rubber compounds whether the car is driven often or not.

Tires on a 1951 Ford should be inspected before every drive, and more carefully before any longer outing. Look for sidewall cracking, cuts, bulges, irregular wear, embedded debris, and signs of aging around the bead and valve area. Since these are vintage-style bias-ply applications, pressure retention and visible shape should be checked closely after the car has been sitting.

A quick walk-around catches many problems before they become a roadside issue. On an older car, a tire that has lost pressure can also place extra strain on wheels, suspension components, and steering behavior that was never especially forgiving by modern standards. If your setup uses tubes, include valve stems and any signs of slow leakage in the inspection routine rather than focusing only on tread and sidewalls.

The 1951 Ford Custom uses a 670-15 bias-ply fitment in the coverage here, and bias-ply construction is the era-correct tire type for an early-1950s American Ford. That aligns with the way domestic passenger cars of the period were ordinarily equipped before radial tires became common in the U.S. market. A specific original-equipment brand should be confirmed through factory literature or marque references if absolute historical accuracy matters for your car.

For restoration work, the most important first step is getting the size and construction family right. Once 670-15 bias-ply is confirmed for the car, the next layer is choosing the sidewall style that best matches how the Custom is being presented, whether restrained or more upscale. Marque clubs, factory brochures, and judging manuals are the best sources when you need to sort out market-specific or trim-sensitive appearance details.

Correct tire fitment matters on a 1951 Ford because judges and knowledgeable enthusiasts notice size, construction, and sidewall style very quickly. A car from this period is expected to wear a bias-ply style tire in the proper numeric size for its model, and an obviously incorrect wheel diameter or inappropriate sidewall treatment can stand out even to casual observers. Authentic appearance at the tire level contributes to the overall credibility of the restoration.

That does not mean every event uses the same standard, but it does mean the tire should support the story the car is telling. A local driver-quality car may have more latitude than a concours-targeted restoration, while marque-specific judging can be much stricter about visual details. If your 1951 Ford is being prepared for formal competition, verify the accepted size and sidewall presentation with the hosting club before making a final tire decision.

On a 1951 Ford, the difference between blackwall and wide whitewall tires is primarily visual, but that visual change is a major part of period character. Both sidewall styles are available within the listed 670-15 and 600-16 fitments, so the choice is not limited to one model. Blackwalls present a simpler, more restrained look, while wide whitewalls emphasize the upscale early-1950s style many owners associate with a show-ready postwar Ford.

Selecting between them depends on the personality of the restoration more than on mechanical fitment. A broad white sidewall can transform the stance and formality of a 1951 Ford, especially on a clean stock wheel and hubcap combination. If authenticity is the goal, align the sidewall choice with period photos, factory literature, and the presentation standard of the events where the car will appear.

1951 Ford tires can be suitable for highway use when the tires are in good condition, correctly fitted, and used within their intended limits. Both listed sizes are bias-ply fitments, and one 600-16 Avon offering carries an H speed rating, which corresponds to a 130 mph ceiling. Other listed tires do not always show a speed letter in the visible size wording, so the specific tire's sidewall marking should be checked rather than assuming a uniform rating across every 1951 Ford option.

For most real-world classic-car driving, the broader safety picture often depends as much on the car as on the tire. A 1951 Ford has period brakes, steering, suspension, and chassis behavior that deserve just as much respect on the highway as the tire itself. Before any sustained-speed driving, make sure the tires are fresh, properly inflated, and matched to the car's wheels, and then drive the vehicle in a way that suits its age and design.

Inflation pressure for 1951 Ford tires should be chosen by matching the tire size and product to the vehicle's factory guidance and the tire's own rated information. Several listed 670-15 tires show 1450 pounds at 32 psi, while one 670-15 Coker Classic example shows 1550 pounds at 32 psi. Several 600-16 tires show 1400 pounds at 32 psi, and one 600H16 Avon listing shows a 1,433-pound load figure without the same pressure notation format.

Those figures are load-and-pressure references for the individual tires, not blanket instructions to copy from one product to another. Use the original owner's manual or factory literature for vehicle baseline guidance, then make sure the chosen reproduction tire's sidewall and manufacturer recommendations support that setup. Do not transfer a pressure number from a 670-15 tire to a 600-16 tire, or from one brand's product to another, without checking the exact tire first.

Before a longer drive in a 1951 Ford, inspect every tire for cracking, cuts, bulges, tread wear, and signs of age around the sidewall and bead. Confirm cold inflation pressure, check that valve stems are sound, and make sure the spare is usable rather than merely present. On a vintage Ford, tire readiness should be part of a broader pre-drive inspection that also includes brakes, steering, fluids, and the car's basic electrical health.

Longer drives put sustained heat and load into a tire in ways short local outings may not, so small defects become more important. A spare with no air, a weathered valve stem, or an overlooked sidewall split can turn a simple tour into a preventable problem. Give the tire inspection the same attention you would give the mechanical systems, because on a collector car, safe road use depends on the whole package working together.
