1956 Dodge Tire Fitment Guide

1956 Dodge vehicles use three tire sizes: 670-15, 710-15, and 760-15. The Coronet appears with all three sizes, the Royal uses 710-15 and 760-15, and the Custom Royal uses 760-15. All three are bias-ply sizes built for 15-inch rims. Where rim-width guidance is available, 670-15 products appear on 4.50 to 6.00-inch rims depending on the tire, 710-15 products on 5.00 to 5.50-inch rims, and 760-15 products on 5.50 to 6.00-inch rims.

That means year and make alone are not enough to choose a tire for every 1956 Dodge. You should confirm the exact model first, then compare the wheel on the car to the rim-width range shown for the specific tire you are considering. That approach keeps the choice centered on the actual application instead of assuming every mid-Fifties Dodge passenger car used the same section width.

On a 1956 Dodge, 670-15 is a numeric bias-ply tire size. The 6.70 portion is the nominal section width in inches, and the 15 identifies the wheel diameter in inches. It is not a modern metric radial size, and it does not carry an aspect ratio in the way a P-metric tire does. On 1956 Dodge applications, 670-15 is associated with certain Coronet fitments.

Understanding that code helps you avoid mixing eras of tire sizing. A 670-15 buyer is usually trying to preserve the original mid-Fifties bias-ply look and fit rather than substitute a later-format radial by guesswork. If your car is a Coronet, compare the wheel width and the stance you want before choosing among the available blackwall and wide whitewall versions.

No, 1956 Dodge models do not all use the same tire size. The Coronet spans 670-15, 710-15, and 760-15 fitments, the Royal uses 710-15 and 760-15, and the Custom Royal uses 760-15. Every size in the range is a 15-inch bias-ply, but the section width changes from model to model and, in some cases, within the same model family.

That variation is typical of a make with several trim and body-style levels in the same year. A buyer with a Custom Royal can narrow the search more quickly than a Coronet owner, while Coronet and Royal owners should verify the tire size already on the car, compare it to the wheel width, and use the model page to zero in on the most appropriate fitment.

1956 Dodge tires are offered in several period-appropriate sidewall styles depending on size. The 670-15 range includes blackwall and wide whitewall choices, the 710-15 range includes blackwall and wide whitewall choices, and the 760-15 range includes narrow whitewall and wide whitewall versions. Those sidewall differences change the car’s visual character even when the tire size itself stays the same.

For a mid-Fifties Dodge, whitewall selection is often as important visually as the size code. Wider whitewalls generally suit a dressier showroom-correct look on upscale cars, while blackwalls create a plainer, more understated appearance. If authenticity matters for a judged restoration, compare your car’s trim level, period photography, and event standards before deciding between blackwall, narrow whitewall, and wide whitewall treatments.

Several brands cover 1956 Dodge fitments. The 670-15 size is available from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. The 710-15 size is available from BFGoodrich and Firestone, while the 760-15 size is available from BFGoodrich, Coker Classic, and Universal Vintage Tire. All of the listed offerings for these sizes are bias-ply tires.

That spread gives buyers room to choose by brand heritage, sidewall treatment, and the exact sizing they need for their model. The main step is to work from the correct tire size first, then compare the available brands within that size rather than crossing from one size to another. On a 1956 Dodge, appearance and proper fit usually matter more than brand loyalty alone.

For a 1956 Dodge using 710-15 tires, BFGoodrich and Firestone both offer bias-ply fitments for 15-inch rims with the same stated load rating of 1550 pounds at 32 psi on the listed products. The available rim-width range shown for both brands is 5.00 to 5.50 inches. The visible differences in the listed range come from sidewall presentation and product weight, with BFGoodrich offered in blackwall and wide whitewall versions and Firestone shown in blackwall.

That makes the decision less about basic fit and more about the look you want on the car. A buyer chasing a more formal mid-Fifties presentation may lean toward one of the BFGoodrich whitewall versions, while a simpler blackwall look can be matched either way. Since the fit dimensions shown are alike, the final choice often comes down to restoration style and brand preference.

Rim-width requirements for 1956 Dodge tires depend on the size you are using. The 670-15 products shown here fit rims from 4.50 to 6.00 inches wide, depending on the specific tire. The 710-15 products are shown on 5.00 to 5.50-inch rims, and the 760-15 products on 5.50 to 6.00-inch rims. All of these tires use a 15-inch rim diameter.

That is why wheel verification matters even when two tires share the same 15-inch diameter. A 15-inch wheel can still be the wrong width for a given tire, especially if the car has had wheels changed over the years. Before selecting a tire for a 1956 Dodge, measure the wheel or confirm its width so the tire’s approved rim range and the wheel on the car actually match.

Original 1956 Dodge wheels can often work across the listed tire sizes in the sense that 670-15, 710-15, and 760-15 all mount on 15-inch rims. Diameter compatibility is only part of the equation, though, because the published rim-width ranges tighten as the tire gets larger. A 670-15 may suit a narrower wheel than a 760-15, even though both are built for the same rim diameter.

That means you should not assume any original 15-inch Dodge wheel is automatically suitable for every listed size. If you are moving from one factory-style size to another, confirm the wheel width against the specific tire’s approved range first. That is especially important on Coronets, where more than one size appears and past wheel swaps are common on long-restored cars.

A 1956 Dodge should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment. Bias-ply tires can develop temporary flat spotting more readily than modern radials when they sit for long periods, so steady inflation pressure and occasional movement help. Clean floors and a barrier under the tires can also reduce moisture exposure from concrete.

If the car will sit for months, roll it periodically or place it on stands in a way that does not strain the suspension. Keeping the car from remaining motionless in one spot protects the tire shape and sidewalls. For a collector 1956 Dodge, good storage habits matter as much as mileage because aging usually comes from time, environment, and inactivity rather than constant use.

Tires on a 1956 Dodge should be judged more by age than by tread depth or miles traveled. A practical collector-car rule is to inspect them closely once they are about five to seven years old and to treat around ten years from the date code as a serious replacement point, even if the tread still looks usable. Low-use vintage cars often age tires out long before they wear them out.

That matters because many collector Dodges see short seasonal drives, parades, and shows rather than daily service. Check the DOT or date marking on the tire you have, watch for sidewall cracking and hardening, and do not assume a good-looking old bias-ply is still ready for road use. Age-based replacement is the safer standard for a car of this era.

Tires on a 1956 Dodge should be inspected before every drive and again before any extended trip. Look for cracking in the sidewall, cuts, bulges, uneven wear, embedded objects, and signs that the tire is losing pressure. On a collector car that may sit between outings, a visual walkaround catches aging problems that would be obvious much earlier on a frequently driven modern car.

A longer outing deserves a more detailed check, including spare-tire condition and valve-stem health. If the car has been parked for weeks or months, pay attention to how the tires feel in the first miles in case a bias-ply flat spot needs time to work out. Regular inspections are one of the simplest ways to keep a 1956 Dodge enjoyable and predictable on the road.

A 1956 Dodge Coronet would have been fitted in bias-ply construction when new, which aligns with the sizes used across the model’s fitment range here: 670-15, 710-15, and 760-15. Mid-Fifties American passenger cars were still bias-ply territory, and the Coronet’s size variation reflects different applications within the model rather than a shift to a different construction type. The key is selecting the size that matches the specific Coronet you own.

For a restoration, that means confirming more than just the make and year. Original-size expectations can vary by body style, trim presentation, and market practice, so marque clubs, factory literature, and surviving original cars are useful checks before finalizing the fitment. Once the size is confirmed, sidewall style becomes the next authenticity decision for matching the car’s period appearance.

Correct tire fitment matters on a 1956 Dodge because judges and knowledgeable enthusiasts often notice size, construction, and sidewall style immediately. A car shown for originality is expected to wear a tire size appropriate to its model and a bias-ply construction consistent with the period. A mismatched sidewall treatment or a size that does not belong on that particular Dodge can stand out even to casual observers.

The level of scrutiny depends on the event, but tire details are part of the car’s overall authenticity story. A high-end restoration should match the model’s proper size first and then choose a sidewall treatment that suits the car’s trim level and the standards of the show. Marque-specific judging rules remain the best reference when you are building a 1956 Dodge for points competition.

For a 1956 Dodge in 760-15, BFGoodrich and Coker Classic both offer bias-ply tires for 15-inch rims with listed load ratings up to 1710 pounds at 32 psi on applicable products. The published rim-width range shown for both is 5.50 to 6.00 inches where that information appears. The visible distinctions come from sidewall presentation, with BFGoodrich offered in narrow and wide whitewall versions and Coker Classic shown in a wide whitewall version.

That makes the comparison useful for restorers focused on appearance. If your 1956 Dodge needs a narrower whitewall look, BFGoodrich provides that option in this size, while buyers pursuing a broad whitewall treatment can compare both brands on style and preference. Since the basic load and rim-width figures overlap closely, the decision usually turns on sidewall appearance rather than a major fitment difference.

1956 Dodge tires in the sizes listed here are bias-ply designs, and no speed rating is shown in the available size markings for these products. A properly fitted, fresh bias-ply tire in good condition can be used for normal road driving, but highway behavior will reflect the period design, with more wander, groove-following, and response differences than a later radial. On a mid-Fifties Dodge, the car’s brakes, steering, suspension condition, and overall mechanical health are often just as important as the tire itself.

Practical safety comes from keeping speeds sensible, maintaining correct inflation, and driving the car within its vintage character. Long freeway runs are easier when the chassis is sorted and the tires are recent, evenly worn, and properly matched to the wheels. Before using a 1956 Dodge regularly at highway speed, inspect the whole running gear rather than treating tire selection as the only factor.

For 1956 Dodge tires, the listed load figures shown on applicable products use 32 psi as the reference point: 670-15 tires are shown up to 1450 pounds at 32 psi and 1550 pounds at 32 psi depending on product, 710-15 tires are shown at 1550 pounds at 32 psi, and 760-15 tires are shown up to 1710 pounds at 32 psi. Those figures describe tire capability at that pressure, not necessarily the exact operating pressure your Dodge should run.

Use the factory owner’s manual or period service information for the vehicle’s recommended inflation target, then compare it with the tire maker’s specifications for the exact reproduction tire you choose. Do not transfer a pressure number from one size to another just because the rim diameter matches. Proper pressure affects ride, tread wear, and steering feel on a bias-ply-equipped 1956 Dodge more than many owners expect.

Before taking a 1956 Dodge on a longer drive, inspect all five tires for cracks, cuts, bulges, irregular wear, and proper inflation, and make sure the spare is usable. Look closely at valve stems and bead areas, especially on a car that has spent much of its life stored. Since these are bias-ply fitments, also pay attention to any vibration or flat-spot feel during the first miles after the car has been sitting.

A good tire check should be part of a broader pre-trip routine that includes brakes, steering play, wheel bearings, fluids, lights, and cooling-system condition. Older collector cars often reveal problems only once they are fully warmed up and driven at sustained speed. A careful inspection before departure makes a longer outing in a 1956 Dodge more enjoyable and reduces the chance of a preventable roadside interruption.
