1948 Dodge Tire Fitment Guide

1948 Dodge vehicles use four sizes, and they are model-specific rather than shared across the whole make. The 1948 Dodge 7 Passenger uses 650-16 or 700-15, while 1948 Dodge Custom & Deluxe models use 6.50-15 or 710-15. The 650-16 size mounts on 16-inch rims with listed rim widths of 4.50 to 5.00 inches, while both 700-15 and 710-15 mount on 15-inch rims with listed rim widths of 5.00 to 5.50 inches.

That means year and make alone are not enough to choose tires for a 1948 Dodge. Start by identifying the exact model, then confirm whether the car is actually wearing 15-inch or 16-inch wheels before narrowing to sidewall style and brand. On a car that has changed hands or been restored decades ago, checking the wheel and the size already fitted can prevent ordering a tire that is correct for the year but wrong for the car.

A 650-16 marking on a 1948 Dodge is a period numeric bias-ply size. The 6.50 portion identifies the tire's nominal section width in inches, and the 16 identifies the wheel diameter in inches. On 1948 Dodge applications, 650-16 is used on the 7 Passenger and is offered in traditional bias-ply construction with both blackwall and wide whitewall versions.

The important thing for a buyer is that 650-16 is not interchangeable with a 15-inch fitment simply because the car is also a 1948 Dodge. It belongs to a specific model group and wheel diameter. If your 7 Passenger still has its 16-inch wheels, 650-16 keeps you in the right postwar sizing family and lets you choose the visual style that best matches your restoration.

No, 1948 Dodge models do not all use the same tire size. The 7 Passenger uses 650-16 or 700-15, while the Custom & Deluxe group uses 6.50-15 or 710-15. That split matters because one branch of the lineup uses a 16-inch fitment option and the other stays in 15-inch sizing.

This is one of those year-make combinations where the model name matters immediately. A buyer who knows only that the car is a 1948 Dodge still needs to sort out whether it is the larger 7 Passenger or a Custom & Deluxe passenger car before picking a size. Once that is settled, the decision becomes much more straightforward because all of the listed choices remain in bias-ply construction and period-correct visual territory.

1948 Dodge tires are available in both blackwall and wide whitewall styles in the listed 650-16, 700-15, and 710-15 sizes. BFGoodrich and Firestone appear across several sizes with both looks, while Coker Classic appears in blackwall form in 650-16 and Garfield appears in wide whitewall form in 650-16. Sidewall styling was an important visual cue in the late 1940s, especially on fuller-bodied American cars.

A blackwall tire generally suits a more restrained or practical presentation, while a wide whitewall gives a stronger postwar luxury and dress-up look. The right choice depends on how your 1948 Dodge is being restored and how closely you want the finished car to reflect period showroom character. If authenticity for judged events matters, compare your chosen sidewall style with period photos, factory literature, and marque-club guidance for your exact body style.

Several brands cover 1948 Dodge fitments, including BFGoodrich, Firestone, Coker Classic, Garfield, and STA. The 650-16 size includes BFGoodrich, Coker Classic, Firestone, and Garfield, while 700-15 includes Firestone, BFGoodrich, and STA. The 710-15 size includes BFGoodrich and Firestone, all in bias-ply construction suited to period-correct applications.

Brand choice on a 1948 Dodge often comes down to the combination of sidewall appearance, tread character, and how closely you want the finished tire to evoke a late-1940s American look. BFGoodrich and Firestone give broad coverage across the listed sizes, while Garfield and STA fill more specific visual or use-case niches. Once you know your correct size, comparing the available brands within that size is the most useful next step.

In 700-15 for the 1948 Dodge, both Firestone and BFGoodrich offer bias-ply tires on 15-inch rims with a listed maximum load capacity of 1700 pounds at 32 psi and a rim width range of 5.00 to 5.50 inches. Firestone appears in both blackwall and 4.125-inch whitewall form, while BFGoodrich appears in a 4.125-inch whitewall version. The listed weights are close, with Firestone examples at 26 to 29 pounds and the BFGoodrich example at 28 pounds.

That means the practical difference is less about major fitment changes and more about sidewall presentation, tread family, and brand preference within the same basic specification. On a 1948 Dodge 7 Passenger using 15-inch wheels, either line stays in the proper bias-ply category. The smartest comparison is to decide first whether you want blackwall or wide whitewall, then compare the series that deliver that look in your chosen brand.

1948 Dodge rim width requirements depend on the tire size. The 650-16 size is listed for 4.50 to 5.00-inch rims, while both 700-15 and 710-15 are listed for 5.00 to 5.50-inch rims. All three of those sizes also have clearly listed rim diameters, with 650-16 on 16-inch wheels and the others on 15-inch wheels.

Rim width matters because even a correct diameter tire can behave poorly if the wheel is too narrow or too wide for the casing. Before fitting new tires to a 1948 Dodge, measure the wheel or verify it against the wheel already on the car instead of assuming every original-looking steel wheel is the same. That is especially helpful on long-restored cars where wheels may have been swapped decades earlier.

The listed 1948 Dodge tire products are bias-ply offerings, but tube status is not uniformly called out in every product description. That means the right approach is to confirm the sidewall marking and the wheel type for the exact tire you are considering rather than assuming every product in a given size is configured the same way. On collector vehicles of this era, tube use often depends on both the tire's marking and the design and condition of the wheel.

For a 1948 Dodge, the practical step is to treat tube fitment as part of the wheel-and-tire package, not as an afterthought. If the wheel is an original-style rim, have it inspected for corrosion, bead-seat condition, and valve-stem integrity at the same time. Matching the tire, tube decision, and wheel condition correctly helps preserve ride quality and reduces the chance of avoidable setup problems after installation.

Original 1948 Dodge wheels cannot be treated as universal across all listed sizes, because the fitments split between 15-inch and 16-inch rim diameters. A 650-16 requires a 16-inch wheel, while 700-15, 6.50-15, and 710-15 are 15-inch fitments. Listed rim width ranges also differ between the available sizes where published.

That means wheel compatibility starts with diameter, then moves to width. A buyer working with a 7 Passenger should verify whether the car is on its 16-inch or 15-inch setup before choosing tires, while a Custom & Deluxe owner should still confirm the actual wheel even though both listed sizes are 15-inch. Using the original wheel is often possible, but only after confirming it matches the selected tire's basic dimensional requirements.

A stored 1948 Dodge should be kept away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age sidewalls prematurely. Clean, dry floors and stable temperatures are better than damp concrete corners or outdoor carports. Because 1948 Dodge fitments here are all bias-ply, long static storage can encourage flat-spotting more readily than many modern radials.

If the car will sit for extended periods, keep the tires properly inflated and move the car occasionally so the same section of casing is not carrying the load for months at a time. Some owners also use stands to reduce sustained weight on the tires during long-term storage, while still supporting the suspension appropriately. Good storage habits preserve both appearance and driving quality when the car returns to the road.

Tires on a 1948 Dodge are usually judged by age and condition more than mileage, since collector cars often see light annual use. A sensible rule is to evaluate them closely once they reach the five-to-seven-year range and to treat roughly ten years as a point where replacement deserves serious consideration, even if tread depth still looks adequate. The DOT date code on the tire helps establish the actual age.

That matters because a lightly driven postwar Dodge can wear very little tread while the rubber and casing continue to age. Cracking, hardening, persistent air loss, vibration, or changes in ride quality can all matter more than the odometer. If the tires came with the car and their age is uncertain, confirming the date code is one of the simplest ways to decide whether the next drive should be routine enjoyment or a tire replacement project first.

Tires on a 1948 Dodge should be inspected before every drive and again before any longer outing. Check for visible sidewall cracking, cuts, bulges, irregular wear, and pressure loss, and look at the spare as carefully as the four road tires. On an older wheel-and-tire package, valve stems also deserve close attention because age can affect them even when the car is seldom used.

Routine inspection is especially important on a collector car because problems often develop slowly between drives rather than during daily use. A Dodge that feels fine on a short neighborhood run may reveal vibration, heat buildup, or pressure loss only when asked to travel farther at steady road speed. Building a quick pre-drive habit around tires, valves, and the spare can prevent a small issue from interrupting a much larger mechanical outing.

A 1948 Dodge 7 Passenger would have been fitted in the bias-ply era, and the sizes associated with that model group are 650-16 and 700-15. Both are period numeric bias-ply sizes and align with the kind of sizing convention American manufacturers used in the late 1940s. The exact original tire choice can still vary with body style, wheel equipment, and how the car was specified when new.

For restoration purposes, the most important point is that a bias-ply tire in the correct size family keeps the car within period expectations. If you are trying to verify the exact as-delivered setup for a particular 1948 Dodge 7 Passenger, compare surviving factory literature, original photos, and marque-club resources before settling on a final size and sidewall style. That extra step is worthwhile when authenticity matters as much as drivability.

Correct tire fitment matters on a 1948 Dodge because judges and knowledgeable enthusiasts often notice size, construction type, and sidewall style immediately. A postwar Dodge restored for authenticity is generally expected to wear a period-appropriate bias-ply tire in the right size for its model group. A mismatched wheel diameter, the wrong size family, or an overly modern visual treatment can distract from an otherwise careful restoration.

That does not mean every show uses the same standard, but it does mean tire choice is part of the car's presentation rather than a minor detail. If your goal is concours-level accuracy, compare your chosen size and sidewall style against period references and ask a Dodge marque club what is considered correct for your event. Getting those details right can elevate the whole stance and authenticity of the finished car.

In 710-15 for the 1948 Dodge, both BFGoodrich and Firestone offer bias-ply tires for 15-inch rims with a listed maximum load capacity of 1550 pounds at 32 psi and a rim width range of 5.00 to 5.50 inches. BFGoodrich appears in blackwall plus more than one wide whitewall treatment, while Firestone appears in blackwall form in the listed selection. Published weights are close, with BFGoodrich examples around 21 to 23 pounds and the Firestone example at 24 pounds.

For a restoration, the practical distinction is usually visual rather than dimensional because the basic fitment envelope is very similar. If your 1948 Dodge Custom or Deluxe is being finished to a more formal late-1940s look, the wider whitewall options may matter as much as the brand name itself. If your goal is a simpler, more understated presentation, blackwall versions keep the car in a correct period category without the brighter sidewall emphasis.

1948 Dodge tires can be suitable for highway use when they are the correct size, in sound condition, and inflated properly, but they are still bias-ply tires with the manners of their era. No explicit speed ratings are shown in the listed size markings here, so the better guide is to operate the car within the limits of the tire's condition and the vehicle's own postwar chassis, braking, and suspension character. A healthy tire package is only one part of safe road use on a 1948 automobile.

For a buyer, that means evaluating the whole car rather than focusing on the tire alone. Fresh bias-ply tires can serve well on normal road outings, but they should be paired with realistic expectations about steering response, tracking, and stopping distances compared with newer vehicles. Before any regular highway use, make sure the alignment, wheel condition, suspension, and brakes are as ready as the tires themselves.

Inflation pressure for 1948 Dodge tires should begin with the vehicle manufacturer's recommendation for the specific model and should never be copied casually from one size to another. Among the listed products, 650-16 tires are shown with a maximum load capacity of 1580 pounds at 32 psi, 700-15 tires at 1700 pounds at 32 psi, and 710-15 tires at 1550 pounds at 32 psi where load figures are given. Those are tire ratings, not automatic running-pressure instructions for every car.

The practical approach is to use the original owner's manual or marque guidance for the car's intended operating pressure, then confirm that your chosen reproduction tire's rating supports that application. Running every size at its maximum stamped pressure can change ride quality and contact patch behavior in ways the car was not meant to have. Pressure choice should suit the exact size, vehicle weight, and intended use of your 1948 Dodge.

Before a longer drive in a 1948 Dodge, inspect every tire for cracking, cuts, bulges, tread separation signs, and pressure loss, and do not ignore the spare. Verify that the wheel hardware is secure and that the valve stems are in good condition, especially on an older wheel-and-tire setup. Tire condition should be checked alongside the rest of the car's basic roadworthiness because a postwar Dodge depends on the whole mechanical system working together.

A longer outing is where age-related issues tend to reveal themselves, so it is smart to include the tires in a broader pre-trip routine covering brakes, cooling system, steering, lights, and fluid levels. On bias-ply tires, also pay attention to any vibration or pull that feels different from the car's normal character. Catching those signs early can turn a disrupted trip into a simple garage correction instead.
