1955 Dodge Tire Fitment Guide

1955 Dodge vehicles use two tire sizes: 710-15 and 670-15. The 710-15 size fits both the 1955 Dodge Coronet and 1955 Dodge Royal, while 670-15 is used on the 1955 Dodge Coronet only. Both sizes mount on 15-inch rims, but their approved wheel-width ranges differ by product, with 710-15 commonly listed for 5.00- to 5.50-inch rims and 670-15 appearing on ranges that include 4.50- to 5.00-inch and 5.00- to 6.00-inch applications depending on the tire.

That means the first question is not just year and make, but model and wheel. A Royal owner is usually headed toward 710-15, while a Coronet owner needs to confirm whether the car was set up for 710-15 or 670-15 and whether the current wheels still match that size’s approved width range. If the car has been restored, modified, or had wheels swapped over the years, a quick check of wheel width and existing tire markings is the safest starting point.

On a 1955 Dodge tire, 710-15 is a numeric bias-ply size. The 710 portion identifies the tire’s nominal section-width class in the older American numeric system, and the 15 identifies the wheel diameter in inches. There is no radial construction marker in the code, which matches the bias-ply construction used in the available 710-15 offerings for 1955 Dodge applications.

For a buyer, that old-style sizing tells you you’re looking at a period-correct mid-century format rather than a modern metric radial code. It also helps explain why sidewall styling is such a big part of the decision in this size, since blackwall and wide whitewall versions are both available. If your 1955 Dodge is a Royal, or a Coronet that uses the larger fitment, 710-15 is the code to match before you compare brands or whitewall widths.

No. The 1955 Dodge Royal uses 710-15, while the 1955 Dodge Coronet appears with both 710-15 and 670-15 depending on the application. Even though both sizes fit 15-inch rims, they are not interchangeable by assumption because the tires are built for different width classes and can call for different approved wheel-width ranges.

That difference matters most for Coronet owners. A Royal owner can usually move directly to confirming wheel width and sidewall style within 710-15, but a Coronet owner should verify the current wheel and existing tire size before choosing a replacement. If the car is being judged, model accuracy also matters, since a correct-looking 1955 Dodge restoration depends on matching the car to the right size family as well as the right sidewall treatment.

The right choice for a 1955 Dodge is determined by model application and wheel setup, not by switching between two different construction types. Both 710-15 and 670-15 are bias-ply sizes on 15-inch rims, but 710-15 fits both the 1955 Dodge Coronet and Royal, while 670-15 is tied to Coronet applications only. The 710-15 products shown are built around 5.00- to 5.50-inch rim widths, while 670-15 products span narrower and wider approved ranges depending on the tire.

A Royal owner should focus on 710-15. A Coronet owner should choose the size that matches the wheel and application already on the car, especially if originality matters or the car has been restored with stock-style steel wheels. Once the size is settled, the next decision becomes appearance: blackwall for a plainer service look or wide whitewall for the fuller mid-1950s presentation many owners want on a show-quality Dodge.

1955 Dodge tires are available in both blackwall and wide whitewall styles. The 710-15 size includes blackwall and wide whitewall offerings from BFGoodrich and Firestone, while 670-15 includes blackwall and wide whitewall versions from Firestone, US Royal, Coker Classic, and Universal Vintage Tire. That gives owners flexibility to match anything from a more restrained factory look to the brighter whitewall presentation that defined many upscale mid-1950s American cars.

Sidewall choice has a strong effect on the finished look of a 1955 Dodge even when the size stays the same. A wide whitewall generally suits a more formal restoration theme and highlights the styling of the period, while blackwall tires can make the car look more understated and work well on drivers or less heavily dressed builds. If you are restoring for an event, check the expected sidewall treatment for your exact model and market before making the final call.

Several brands cover 1955 Dodge fitments. In 710-15, the available brands are BFGoodrich and Firestone. In 670-15, the available brands are Firestone, US Royal, Coker Classic, and Universal Vintage Tire. All of the listed options for this year and make are bias-ply tires, which keeps the construction era-appropriate even though the brands and sidewall presentations vary.

Brand choice on a 1955 Dodge usually comes down to the look you want and the specific size your car uses. Some owners prefer a recognizable legacy name tied to American motoring history, while others focus more on obtaining the right whitewall treatment or wheel-width compatibility for their car. Once you narrow the size, compare the available brands by sidewall style, listed load information, and approved rim-width range rather than treating all same-size tires as identical.

Rim width depends on the tire size and, in the case of 670-15, sometimes the specific product. The 710-15 tires shown for 1955 Dodge applications are listed for 5.00- to 5.50-inch rims. The 670-15 tires appear with approved rim-width ranges of 4.50 to 5.00 inches on some products and 5.00 to 6.00 inches on others, so the exact tire matters just as much as the size code.

That is why wheel measurement should happen before the order decision, especially on a Coronet. A 15-inch diameter alone is not enough if the wheel width falls outside the tire’s approved range. Measure the wheel at the bead seats if possible and compare it to the tire you are considering, rather than assuming every 670-15 or every 710-15 is interchangeable across every 1955 Dodge wheel.

The available 1955 Dodge fitments shown here are bias-ply tires, but the size markings provided do not add TT or TL designations. That means tube use should be confirmed at the individual tire level and matched to the wheel type on the car. On an older steel wheel, tube decisions often depend on the tire’s sidewall marking, the wheel’s condition, and whether the rim was originally intended for tube-type service.

A practical approach is to treat tube choice as part of the wheel-and-tire package rather than as a separate afterthought. If your 1955 Dodge still wears original-style wheels, inspect the rim for pitting, check the valve hole, and confirm the tire’s own marking before assembly. Tube-compatible valve stems and a sound spare should also be part of the plan if the car is driven regularly or taken on longer trips.

Original 1955 Dodge wheels can potentially be used with both listed sizes only if the wheel has the correct 15-inch diameter and falls within the approved width range for the specific tire. Both 710-15 and 670-15 use 15-inch rims, so diameter compatibility is shared. Width compatibility is where the decision changes, because 710-15 products are centered around 5.00- to 5.50-inch rims, while 670-15 products span different ranges depending on the exact tire.

That means a wheel that physically accepts one size is not automatically ideal for the other. If your Coronet has been restored or mixed with parts from another car, measure the actual wheel before assuming either size is appropriate. Keeping the original wheel can absolutely work, but the best path is to match the wheel to the tire’s approved range rather than trying to make the tire conform to a wheel that was chosen for a different application.

A 1955 Dodge should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can age rubber. Because the available tires for 1955 Dodge applications are bias-ply designs, they are more prone to temporary flat-spotting during long static storage than a modern radial would be. Clean floors, stable temperature, and proper inflation all help protect the tire casing while the car sits.

If the car will be parked for an extended period, move it occasionally so the same section of the tire is not carrying the load month after month. Some owners also use stands to reduce sustained weight on the tires, though the suspension should still be supported correctly. Tire covers are worthwhile if the car sits near windows, and a quick pressure check before and after storage is smart on any collector Dodge.

Tire life on a 1955 Dodge is usually judged more by age and condition than by miles, because collector cars often see limited annual use. A sensible rule is to begin evaluating the tires closely once they are about five to seven years old and to treat the ten-year mark as a strong point for replacement consideration, even if the tread still looks good. The DOT date code, sidewall condition, and how the tire has been stored all matter more than the odometer on a hobby car.

That approach is especially important on a car that spends long periods parked and then gets driven at road speed without much warning. A wide-white bias-ply tire can still look presentable while age is already affecting the rubber beneath the surface. If your 1955 Dodge is a weekend cruiser, a show car, or both, treat calendar age and regular inspections as the real maintenance schedule rather than waiting for obvious tread wear.

Tires on a 1955 Dodge should be checked before every drive and inspected more thoroughly before any longer outing. Look for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and pressure loss, and make sure the spare is in comparable condition if you plan to travel any distance. On older collector cars, a tire that appears fine at a glance can still reveal issues once you look closely at the sidewall and valve area.

A brief pre-drive walkaround is often enough to catch the problems that strand vintage cars: low pressure, weather-checking, or a damaged stem. A more complete inspection a few times each season should include checking the inside sidewall when possible and confirming that each tire still holds pressure consistently. If you are using tubes, pay extra attention to valve stems and any signs of heat or abrasion around the rim opening.

A 1955 Dodge Coronet would have been fitted originally with bias-ply tires, which aligns with the available 670-15 and 710-15 fitments shown for that model year. Both sizes appear on Coronet applications, while the Royal stays with 710-15. Original-equipment branding could vary by market and production details, so the key authenticity point is matching the Coronet to the correct bias-ply size and the sidewall presentation that fits the car’s trim level and restoration goal.

For most restorers, construction type is the first authenticity checkpoint and sidewall style is the second. A period-correct Coronet should look like a mid-1950s Dodge when viewed from the side, and that means choosing between blackwall and wide whitewall in a way that matches the car’s intended presentation. If the car is headed for serious judging, confirm the expected size and whitewall treatment with marque clubs or factory literature tied to your exact body style.

Correct tire fitment matters a great deal when showing a 1955 Dodge because judges and knowledgeable enthusiasts notice size, construction, and sidewall style immediately. A mid-1950s Dodge presented for originality should wear an era-appropriate bias-ply tire in the right size family for the model, with a sidewall look that suits the car. A mismatch in size or an obviously modern visual treatment can distract from an otherwise accurate restoration.

For a Royal, that usually means getting the 710-15 fitment and period styling right. For a Coronet, it means first establishing whether the car should be on 670-15 or 710-15 before deciding on blackwall versus whitewall. Event standards vary, so owners chasing points should verify the judging expectations of the specific club or concours rather than assuming that any vintage-looking tire will satisfy an originality-focused class.

The BFGoodrich and Firestone 710-15 options for a 1955 Dodge share the same basic fitment class, with 15-inch diameter, bias-ply construction, 1550-pound load listings at 32 psi, and a 5.00- to 5.50-inch rim-width range. The practical differences shown here are mainly presentation and listed weight. BFGoodrich appears in both blackwall and wide whitewall versions, while Firestone is shown in blackwall, and the listed weights vary slightly among the products.

That makes this a styling and preference decision more than a fitment one, provided your car uses 710-15. If you want a brighter period look for a more dressed-up Royal or Coronet, the BFGoodrich whitewall options broaden the visual choices. If you are keeping the car more understated, a blackwall version from BFGoodrich or Firestone preserves the same size and load class while changing the appearance rather than the fundamental application.

1955 Dodge tires can be suitable for normal highway use when they are the correct size, properly mounted, in sound condition, and run within their intended service limits. The available tires here are bias-ply designs, so their road manners will feel more period-correct than modern, with more sensitivity to grooves, crown, and steering input than a radial driver may expect. On a healthy mid-1950s full-size Dodge, tire condition and inflation are important, but the car’s own brakes, steering, and suspension condition matter just as much at speed.

Highway confidence on an older Dodge comes from the complete package, not just the tire itself. A fresh set of correct bias-ply tires will not compensate for worn front-end components, old shocks, or marginal brakes. Before sustained highway driving, make sure the tires are age-sound, balanced, and inflated correctly, then treat the car like the 1950s machine it is rather than like a modern sedan with far newer handling and stopping reserves.

The listed load-and-pressure figures for 1955 Dodge tires vary by size and product. In 710-15, the available examples shown carry 1550 pounds at 32 psi. In 670-15, examples include 1450 pounds at 32 psi and 1550 pounds at 32 psi depending on the tire. Those are tire ratings, not a blanket factory inflation rule for every 1955 Dodge application, so they should not be transferred casually from one size or product to another.

Use the car’s original manual or factory guidance as the starting point for operating pressure, then confirm that your chosen tire’s own rated pressure and load limits are being respected. A restored car on reproduction bias-ply tires may need a little more attention here than a modern daily driver because the correct feel and wear pattern can change noticeably with only a few pounds of pressure difference. Check cold pressure regularly rather than guessing by appearance.

Before a longer drive in a 1955 Dodge, inspect every tire for cracking, cuts, bulges, unusual wear, and correct cold pressure, and do the same for the spare. Look closely at valve stems, especially on older wheel-and-tire assemblies, and make sure the tires are seated properly and have no signs of rubbing or impact damage. On a collector car, the tire check should be part of a broader review that also includes wheel fasteners, brakes, steering, suspension, and fluid levels.

Longer trips expose weaknesses that short local drives may not reveal. A bias-ply tire that has been sitting for weeks can smooth out after a few miles, but age cracks, pressure loss, or a damaged stem will only become more serious at sustained speed and heat. If the car has recently come out of storage, give it a short local shakedown first so you can evaluate how the tires and the rest of the chassis behave before committing to distance.
