The 1973 Dodge Coronet sat in the middle of Dodge's changing early-1970s lineup, serving buyers who wanted anything from practical transportation to family wagon duty and big-engine muscle-era attitude. That broad mission shows up clearly in its tire fitment, because this exact model year uses several 14-inch tire sizes across different Coronet configurations. Most primary fitments are vintage alphanumeric bias-ply sizes, while the Wagon also includes an HR78-14 radial fitment. Available choices range from wide whitewalls to redlines, pin white stripes, raised white letters, and radial-equivalent alternatives, so the right selection depends on whether the goal is restoration-style appearance, correct sub-model fitment, or more modern road manners.
Which Tire Size Is Right for The 1973 Dodge Coronet
The 1973 Dodge Coronet uses seven primary tire sizes, and the right one depends on the exact sub-model and engine grouping. Every fitment here stays on a 14-inch rim, but the size and construction can change from one Coronet configuration to another, including one radial fitment. The first step is identifying the correct sub-model before comparing sidewall style, tire series, or radial-equivalent alternatives.
E78-14 is a vintage alphanumeric bias-ply size in which the letter designates the tire's size class, the 78 indicates its profile family, and the 14 identifies the wheel diameter. On the 1973 Dodge Coronet, this is a bias-ply fitment that suits the period driving feel and appearance expected from an early-1970s intermediate. Available choices include a Coker Classic wide whitewall as well as STA blackwall options in Traxion and Transport Highway series. It is the size to evaluate when your Coronet falls into the smaller of the six-cylinder fitment choices and you want to stay with the proper 14-inch format.
F78-14 uses the same vintage alphanumeric sizing system, with the letter marking a larger size class than E78 and the 14 still indicating a 14-inch rim. This is a bias-ply Coronet fitment, making it relevant for owners who want a traditional construction and a period-style stance. In this size, the available product centers on a Coker Classic wide whitewall, which gives the tire a distinctly restoration-oriented appearance. It is an important size to confirm when comparing six-cylinder and 318 or 400 engine Coronets, since it appears across more than one configuration.
H78-14 is a larger vintage alphanumeric bias-ply size, where the H identifies a broader size class, the 78 refers to the profile family, and the 14 is the wheel diameter. For the 1973 Dodge Coronet, this size appears in wagon applications where load-carrying and full-size proportions matter more than muscle-car sidewall styling. The available choice is a Coker Classic wide whitewall, giving this size a traditional and substantial visual character. It is the right starting point when your Coronet is a wagon using the bias-ply fitment rather than the radial alternative.
HR78-14 looks similar to a bias-ply alphanumeric size, but the R in the designation indicates radial construction. On the 1973 Dodge Coronet, that makes it the standout fitment because it reflects a radial primary size rather than a bias-ply one, and it is tied specifically to the Wagon application. Product choices are not shown here, so the real value of this size is understanding that the wagon may be equipped around a radial 14-inch fitment from the start. That makes wheel confirmation and construction choice especially important before selecting a bias-ply-style alternative instead.
G78-14 is another vintage alphanumeric bias-ply size, positioned between F78 and H78 in the traditional sizing hierarchy, with the 14 again identifying a 14-inch wheel. For the 1973 Dodge Coronet, it serves larger non-wagon engine applications that still use a bias-ply tire rather than the lower-profile F70 or G70 performance-style sizes. Available options include BFGoodrich and Coker Classic products with narrow whitewall, dual-white-stripe, and wide whitewall treatments across Silvertown Classic Bias Ply and Coker Classic Bias Ply series. It is the size to examine when tire appearance matters as much as sub-model fitment.
F70-14 is a vintage alphanumeric bias-ply size in which the letter marks the size class, the 70 identifies a lower-profile family than the 78-series sizes, and the 14 is the rim diameter. On the 1973 Dodge Coronet, this size fits the 340 and 440 engine group, so it carries a stronger muscle-era character than the more conservative 78-series fitments. Firestone and Goodyear both offer this size in Wide Oval, Custom Wide Tread, and Speedway Wide Tread lines with redline, pin white stripe, and raised white letter sidewalls. It is the key size for buyers prioritizing performance-era appearance on the correct engine-related Coronet setup.
G70-14 follows the same vintage alphanumeric bias-ply format, but with a larger size class than F70 while retaining the lower 70-series profile family and 14-inch rim fitment. For the 1973 Dodge Coronet, it also belongs to the 340 and 440 engine group and represents the larger of the two muscle-oriented bias-ply choices. Available products come from Firestone and Goodyear with redline, pin white stripe, raised white letter, and blackwall sidewall treatments in Wide Oval and Custom Wide Tread series. It deserves close attention when wheel width, stance, and sidewall style are part of the tire decision.
Sub-model fitment on the 1973 Dodge Coronet is not one-size-fits-all, because different engine groups and the Wagon use different tire sizes and, in one case, different construction. Checking the exact Coronet configuration first prevents choosing the wrong size simply because another 1973 Coronet also uses a 14-inch wheel.

1973 Dodge Coronet 6 Cyl. w/225 Eng.
The 1973 Dodge Coronet 6 Cyl. w/225 Eng. uses either E78-14 or F78-14 bias-ply sizing, making it distinct from the larger and lower-profile V8-oriented fitments. That means tire selection should start with confirming which of those two traditional 14-inch sizes is on the car before comparing whitewall or blackwall product choices.
The 1973 Dodge Coronet Wagon is the only sub-model here that pairs a bias-ply H78-14 fitment with an HR78-14 radial fitment. That makes construction especially important, because a wagon owner may be deciding not just on size, but also whether the vehicle is set up around a bias-ply or radial 14-inch tire.
The 1973 Dodge Coronet w/318 & 400 Eng. uses F78-14 or G78-14 bias-ply tires, placing it between the six-cylinder and high-performance engine groupings in overall fitment. Tire choice here centers on confirming which of those two sizes belongs on the car, then choosing among the available whitewall and series differences.
The 1973 Dodge Coronet w/340 & 440 Eng. uses F70-14 or G70-14 bias-ply tires, the lower-profile alphanumeric sizes most closely associated with muscle-era sidewall styling. Once the exact size is confirmed, the decision usually shifts to sidewall treatment, tire series, and whether a radial equivalent is worth considering.
Bias-Ply to Radial Tire Conversion for the 1973 Dodge Coronet
The 1973 Dodge Coronet's primary tire sizes have several radial-equivalent paths. E78-14 can be matched to 185R14, P195/75R14, or P205/70R14; F78-14 and F70-14 can use 195R14, P205/75R14, P215/70R14, or the 750R14 bias-look radial; H78-14 maps to 215R14, P225/75R14, or P235/70R14; G78-14 and G70-14 map to 205R14, P215/75R14, P225/70R14, or the 800R14 bias-look radial. Recommended rim-width ranges run from 4-6 inches or 5-7 inches depending on size, so wheel width and vehicle clearance should be checked before changing formats.

Important Considerations When Replacing Bias Ply With Radial
Compare overall diameter and section width carefully to ensure proper fit.
Verify recommended rim range (5-7 in) and load needs match your vehicle specifications.
Check fender clearance, steering clearance, and stance before installation.
Consider suspension condition and intended road use when choosing equivalents.
Important Fitment Notes
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Available 1973 Dodge Coronet tire choices span Coker Classic, STA, BFGoodrich, Firestone, and Goodyear, with selections that range from wide whitewalls and narrow whitewalls to redlines, pin white stripes, raised white letters, and blackwalls. Product differences are strongest in the G78-14, F70-14, and G70-14 sizes.
Common 1973 Dodge Coronet tire questions usually come down to sub-model size differences, 14-inch rim fitment, bias-ply versus radial choices, sidewall styling, and what to inspect before putting a collector-era car or wagon back on the road.
Tire Size & Fitment
What tire size fits a 1973 Dodge Coronet?
A 1973 Dodge Coronet can use E78-14, F78-14, H78-14, HR78-14, G78-14, F70-14, or G70-14, depending on the exact sub-model. The six-cylinder car uses E78-14 or F78-14, the Wagon uses H78-14 or HR78-14, 318 and 400 engine cars use F78-14 or G78-14, and 340 and 440 engine cars use F70-14 or G70-14.
The important point is that all 1973 Coronets do not share one universal tire size, even though they all use 14-inch rims. Start by identifying the exact engine grouping or wagon application, then compare the tire already on the car, the wheel size, and the construction before choosing a replacement.
What size rim does a 1973 Dodge Coronet use?
The 1973 Dodge Coronet uses a 14-inch rim across all of its listed tire fitments. That includes E78-14, F78-14, H78-14, HR78-14, G78-14, F70-14, and G70-14, so the wheel diameter remains consistent even though the tire sizes vary by sub-model.
A shared rim diameter does not mean every Coronet can use every listed tire size. Width and overall tire selection still depend on the exact size used by your sub-model, and wheel width should be checked carefully if the car has aftermarket wheels or if a radial-equivalent tire is being considered.
Why does the 1973 Dodge Coronet have more than one tire size?
The 1973 Dodge Coronet covers several configurations, including a six-cylinder model, a Wagon, 318 and 400 engine cars, and 340 and 440 engine cars. Those variations use different tire sizes, and the Wagon is also unique because it includes both a bias-ply H78-14 fitment and an HR78-14 radial fitment.
That variety means tire choice is tied to the exact Coronet you own, not just the model name on the fender. Matching the correct size first helps preserve proper proportions and avoids mixing a lower-profile muscle-era size with a more traditional 78-series or wagon-oriented fitment.
Bias-Ply & Radial Options
Is F70-14 a bias-ply or radial tire for the 1973 Dodge Coronet?
F70-14 is a bias-ply primary tire size for the 1973 Dodge Coronet. It appears on the 340 and 440 engine group and belongs to the lower-profile vintage alphanumeric family that was commonly used on performance-oriented domestic cars of the period.
That matters because an F70-14 bias-ply replacement preserves the original sizing format and the available sidewall styles include redline, pin white stripe, and raised white letter treatments. Anyone considering a radial alternative should compare wheel width, overall dimensions, and clearance rather than assuming the construction change is automatic.
What radial tire sizes are equivalent to F70-14 on a 1973 Dodge Coronet?
Radial equivalents for F70-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, P215/70R14 as a 70-series P-metric radial, and 750R14 as a bias-look radial equivalent. The recommended rim-width range associated with these equivalents is 4-6 inches.
Each option represents a different sizing convention and profile approach, so the decision is not only radial versus bias-ply. Compare the actual wheel width on the car, then verify section width, overall tire dimensions, and fender or steering clearance before choosing one of those alternatives for a 1973 Coronet.
Should I use bias-ply or radial tires on a 1973 Dodge Coronet?
That depends on the exact Coronet configuration and the goal for the car. Most listed 1973 Dodge Coronet fitments are bias-ply primary sizes, while the Wagon also includes an HR78-14 radial fitment, and several bias-ply sizes have radial-equivalent alternatives in metric, P-metric, or bias-look radial form.
A bias-ply tire usually makes the most sense when period-style sizing and appearance are the priority, especially in F70-14 or G70-14 muscle-era applications. A radial alternative can be considered when road use and construction preference matter more, but wheel width, clearance, and the current setup should be confirmed before making the change.
Choosing the Right Tire
What should I consider when choosing a 1973 Dodge Coronet tire?
Start with the exact sub-model and correct primary size, because a 1973 Dodge Coronet may use anything from E78-14 to G70-14 depending on engine grouping or wagon use. After size is confirmed, the next decisions are construction, sidewall style, tire series, and whether a radial-equivalent option belongs in the comparison.
The buying decision changes with the car's purpose. A restoration-minded six-cylinder or wagon may lean toward a traditional whitewall presentation, while a 340 or 440 car may call for redline, pin white stripe, or raised white letter styling. Wheel width and intended driving use should help narrow the final choice.
What sidewall styles are available for 1973 Dodge Coronet tires?
Sidewall choices for the 1973 Dodge Coronet include blackwall, wide whitewall, narrow whitewall, dual-white-stripe, redline, pin-white-stripe, and RWL raised white letter treatments. The exact styles depend on the tire size, with the broadest variety appearing in G78-14, F70-14, and G70-14 applications.
That variety lets the tire change the car's presentation without changing the overall vintage sizing format. A wagon or more formal Coronet can take on a very different look with a wide whitewall, while F70-14 and G70-14 sizes are where muscle-era sidewall treatments become the main part of the selection process.
What brands offer tires for the 1973 Dodge Coronet?
Brands available across 1973 Dodge Coronet tire sizes include Coker Classic, STA, BFGoodrich, Firestone, and Goodyear. Brand choice depends on the size being used, since some fitments have only one or two brand paths while F70-14 and G70-14 offer the broadest mix of Firestone and Goodyear products.
Brand is only one part of the decision. It should be weighed alongside the correct size, the tire series offered in that size, the sidewall treatment you want, and the wheel-width range that matches your current wheels. A narrower product selection in one size usually means fitment should stay the priority over brand preference.
Restoration & Appearance
Which tire should I choose for a period-style 1973 Dodge Coronet?
A period-style 1973 Dodge Coronet should begin with the correct primary size for the exact sub-model, then move to a sidewall and series that match the character of the car. Whitewall bias-ply options suit more conservative or wagon-oriented Coronets, while F70-14 and G70-14 open the door to redline, pin white stripe, and raised white letter choices.
The main goal is to match the tire's visual character to the vehicle's configuration rather than picking a style purely by preference. When exact originality matters, check marque references or vehicle-specific restoration material, because a period-style tire can look appropriate without necessarily proving exact factory delivery details.
How does tire construction affect the appearance of a restored 1973 Dodge Coronet?
Tire construction changes more than ride feel on a restored 1973 Dodge Coronet; it also affects the visual presentation of the car. Bias-ply sizes such as E78-14, F78-14, G78-14, F70-14, and G70-14 preserve the traditional vintage size format, while radial alternatives introduce a more modern sizing language even when they remain close in overall intent.
That difference is especially important if the car is being restored around an early-1970s look. A bias-look radial can help retain a more traditional appearance in sizes where one exists, but it still deserves the same checks for wheel compatibility and clearance as any other radial-equivalent choice.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1973 Dodge Coronet?
Yes, modifications can affect tire fitment on a 1973 Dodge Coronet even when the car still uses a 14-inch wheel. Aftermarket wheel width, wheel offset, lowered suspension, replacement springs, brake changes, or body alterations can all change how an E78-14, F70-14, G70-14, or other Coronet size sits in the wheel opening.
That is why the current setup matters as much as the original application. A Coronet with non-stock wheels may need extra attention to sidewall clearance, steering travel, and fender room, especially if moving from a primary bias-ply size to a radial-equivalent tire with a different sizing convention.
What should I inspect before driving a 1973 Dodge Coronet on new tires?
Before driving a 1973 Dodge Coronet on new tires, inspect the wheels for the correct 14-inch diameter and suitable width, then confirm the tires are mounted in the correct size for the sub-model. It also makes sense to check valve stems, wheel condition, inflation pressure, lug hardware, and the vehicle's basic alignment and suspension condition.
A short road test should be used to watch for rubbing, vibration, pulling, or unusual steering feel. Collector cars often sit for long periods, so it is smart to look over wheel bearings, brakes, and any aged suspension components at the same time rather than assuming the tire change alone prepares the car for use.
How should 1973 Dodge Coronet tires be maintained on a collector car?
Tires on a collector 1973 Dodge Coronet should be checked regularly for pressure loss, tread wear, sidewall cracking, cuts, bulges, and signs of aging from storage. Even a car that is driven sparingly can develop tire issues over time, especially with older bias-ply constructions or long periods parked in one position.
Good storage habits help preserve the tires as much as routine inspection does. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources can reduce deterioration, and moving or driving the Coronet occasionally helps avoid long-term flat spotting and lets you catch problems before a longer trip.
