1955 Dodge Coronet Tires

A 1955 Dodge Coronet uses either 710-15 or 670-15, depending on the exact sub-model. Both are vintage numeric bias-ply sizes built for 15-inch rims, so the correct answer is not the same across every Coronet covered here.

The key step is matching the tire size to the actual sub-model before comparing brands or sidewall styles. Once that is confirmed, selection becomes much easier because both sizes have period-style bias-ply choices and modern radial equivalents that can be evaluated against the car's wheel setup and intended use.

The 1955 Dodge Coronet uses a 15-inch rim with both primary tire sizes covered here. That applies whether the car takes 710-15 or 670-15, since each size is built around the same 15-inch rim diameter.

Rim diameter is only part of the fitment picture, so it still helps to confirm the wheel itself before ordering tires. Width can vary between products, and any wheel that has been changed over the years should be measured so the chosen tire size and construction suit the actual wheel on the car.

The 1955 Dodge Coronet has more than one tire size because the covered sub-models do not share the same fitment. The D 55-1 6 Cyl. uses 710-15, while the D 56-1 6 Cyl. uses 670-15, even though both remain bias-ply tires on 15-inch rims.

That means tire shopping should start with the exact model identification rather than with appearance alone. A wide whitewall or blackwall may look right for the era, but the visual choice comes after confirming which of the two original tire sizes belongs on your specific Coronet.

On a 1955 Dodge Coronet, 710-15 is a bias-ply tire size. It is one of the original-style primary fitments for this vehicle and uses the tall-profile numeric sizing format common on mid-1950s American cars.

A radial alternative may still be considered, but it should be treated as an equivalent option rather than the same construction. Owners who want the traditional stance and presentation usually stay with bias-ply, while owners planning more road miles often compare radial equivalents after checking wheel width, clearance, and overall setup.

Radial equivalents for 670-15 include 195R15 as an 80-series metric radial, P205/75R15 as a 75-series P-metric radial, P215/70R15 as a 70-series P-metric radial, and 670R15 as a bias-look radial. The recommended rim-width range attached to these equivalents is 5-7 inches.

Those choices give a 1955 Dodge Coronet owner several ways to move from the original bias-ply format into radial construction while keeping the same 15-inch rim diameter. The final decision still depends on the actual wheel, the space around the fender and suspension, and how closely the owner wants to preserve a traditional visual presentation.

Start by confirming the car's original size, then compare the available radial equivalent tied to that exact fitment. A 710-15 Coronet has different equivalent choices than a 670-15 Coronet, so the conversion begins with the correct base size rather than a general radial substitution.

Wheel width, rim diameter, tire clearance, and the car's actual condition all matter before changing construction. A Coronet with replacement wheels, suspension work, or body modifications may respond differently than a stock car, so checking the full setup helps avoid problems with fit, appearance, or steering clearance.

The first consideration is the exact size your Coronet uses, since 1955 applications here take either 710-15 or 670-15. After that, the main factors are construction, wheel compatibility, sidewall style, brand, and whether the car is being kept close to a restoration-style presentation or prepared for more regular driving.

A bias-ply tire keeps the original-style format, while a radial equivalent changes the construction and may change the visual character as well. It also helps to compare rim-width specifications, load figures where shown, and the overall look of blackwall versus whitewall options before making a final selection.

1955 Dodge Coronet tires are available in blackwall, narrow whitewall, and wide whitewall styles, depending on the size and product line. Those appearance choices are offered across both 710-15 and 670-15, although the exact mix varies by brand and tire series.

Sidewall style has a strong effect on how a mid-1950s car presents, especially on a restoration-oriented vehicle. A blackwall gives a more restrained look, while narrow and wide whitewalls create a more visibly period-style finish, so the best choice usually depends on the car's trim theme and the owner's visual goals.

Tire choices for the 1955 Dodge Coronet include BFGoodrich, Firestone, Goodyear, US Royal, Universal Vintage Tire, Coker Classic, Excelsior, Avon, and STA across the two primary sizes. Brand availability changes with tire size, so some names appear only in 670-15 while others cover both fitments.

Brand choice is best treated as one part of a broader comparison rather than the whole decision. The more useful approach is to narrow the search by the correct size first, then compare the series, sidewall treatment, rim-width specification, and overall appearance that best matches the car and its intended use.

For a period-style 1955 Dodge Coronet, the starting point is the original-size bias-ply fitment for the exact sub-model: either 710-15 or 670-15. Staying with the correct numeric bias-ply size preserves the tall-profile look and construction style associated with American passenger cars of the mid-1950s.

Appearance then comes down to sidewall treatment and series character rather than size alone. Owners who want the restoration to reflect a specific historical presentation should compare whitewall width carefully and consult marque references or period photography if exact visual authenticity matters more than simply capturing the era.

Tire construction changes more than ride feel on a restored 1955 Dodge Coronet; it also changes how the car looks at a glance. A bias-ply tire keeps the original-style sizing language and visual character, while a radial equivalent can alter the presentation even when it remains within the same general fitment range.

That matters most on a car where stance, sidewall height, and whitewall treatment are part of the restoration plan. A bias-look radial can help bridge that gap for some owners, but it still deserves the same wheel and clearance checks as any other alternative to the original bias-ply construction.

Yes, modifications can affect tire fitment on a 1955 Dodge Coronet even when the tire size itself is correct. Changes to wheels, suspension height, steering components, or body clearance can alter how a 710-15 or 670-15 tire sits and moves within the wheel opening.

A Coronet with aftermarket wheels should have both diameter and width confirmed before a new tire is chosen. Clearance at full steering lock and through suspension travel is also worth checking, especially if the car has been lowered, rebuilt, or fitted with parts that differ from the original wheel and chassis setup.

Before driving a 1955 Dodge Coronet on new tires, inspect the wheels, valve stems, and overall mounting condition, then confirm that inflation matches the tire being used. It also helps to look over suspension and steering components so the car is not putting a fresh set of tires on a worn or unstable foundation.

A short initial drive is a good time to listen for rubbing, feel for pull, and recheck pressure once the tires have settled in. Collector cars that sit for long periods also deserve a broader inspection for brake condition, fluid leaks, and wheel fastener security before regular road use resumes.

Collector-car tires in 710-15 or 670-15 should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Even when tread looks good, a low-use 1955 Dodge Coronet can develop age-related issues such as cracking, flat spotting, air loss, or sidewall damage that are easy to miss.

Routine maintenance should also include checking for cuts, bulges, and uneven wear that may point to alignment or suspension issues. Parking the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and any sign of condition change should be evaluated before the next extended drive.
