1973 Dodge Challenger Tires

A 1973 Dodge Challenger can use 735-14, F78-14, or F70-14 tires, depending on the exact engine and wheel configuration. All three are bias-ply sizes built for 14-inch rims, but they do not apply universally across every Challenger covered here.

The practical first step is identifying the exact sub-model and confirming what is already mounted on the car. A 318-equipped Challenger may use 735-14 or F78-14, while a 340 V8 car may use F70-14 or F78-14, so checking the wheel setup avoids ordering a tire that matches the era but not the actual application.

The tire sizes used on the 1973 Dodge Challenger in this fitment group are all built around a 14-inch rim diameter. That includes 735-14, F78-14, and F70-14, so the wheel diameter remains consistent even though the tire size itself may change by sub-model.

Rim diameter is only part of the fitment picture, so it is still important to verify the wheel width before choosing a replacement tire. That matters even more if the car has aluminum wheels or an aftermarket wheel set, since a 14-inch diameter alone does not confirm that every Challenger tire size is suitable for the wheel already on the car.

More than one tire size applies because 1973 Dodge Challenger fitment varies by engine and wheel combination. The covered 318 and 340 V8 configurations do not all use the same primary size, even though they share the same 14-inch rim diameter and bias-ply construction.

That difference means tire selection should begin with the exact Challenger configuration rather than choosing by model name alone. It also explains why one owner may be looking at a whitewall-oriented 735-14 or F78-14 option, while another is correctly shopping for an F70-14 with redline, pin white stripe, or raised white letter styling.

F70-14 is a bias-ply primary tire size for the 1973 Dodge Challenger. It uses a vintage alphanumeric bias-ply sizing format and appears on certain 340 V8 configurations, where it also carries the broadest range of period-style product and sidewall choices.

That matters because an F70-14 bias-ply tire keeps the car within its original size family and visual character. Owners considering a radial alternative should treat that as a separate fitment decision, then compare wheel width, overall dimensions, and clearance rather than assuming a radial equivalent behaves exactly like the original bias-ply construction.

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. Those options cover traditional metric sizing, modern P-metric sizing, and a radial that preserves a more vintage visual presentation.

Each of those alternatives belongs on a 14-inch wheel, but selection still needs to account for wheel width and vehicle clearance. The recommended rim-width range tied to these equivalents is 4 to 6 inches, so the actual wheel on the Challenger should be checked before treating any one of those sizes as the right conversion.

Start by matching the radial equivalent to the correct original size on the car, since a 1973 Dodge Challenger may use 735-14, F78-14, or F70-14 depending on configuration. Then confirm that the wheel diameter is 14 inches and that the wheel width falls within the recommended range for the equivalent being considered.

A careful conversion also includes checking steering and fender clearance, suspension condition, and the actual wheel setup if the Challenger has aluminum or aftermarket wheels. Radial equivalents are useful alternatives, but the car’s stance, available space, and intended road use should all be reviewed before moving away from the original bias-ply construction.

The first priority is matching the tire to the correct Challenger sub-model and wheel setup, since 735-14, F78-14, and F70-14 do not all apply to every 1973 Dodge Challenger. After that, the key factors are construction type, sidewall appearance, rim-width compatibility, and whether the car is being kept in a traditional bias-ply presentation or evaluated for a radial equivalent.

Product variety also changes by size. F70-14 offers the broadest selection and leans into muscle-era visual choices, while 735-14 and F78-14 support more traditional blackwall and whitewall looks, so the final decision usually comes down to fitment accuracy first and appearance goals second.

Sidewall choices for 1973 Dodge Challenger tires include blackwall, narrow whitewall, wide whitewall, redline, pin-white-stripe, and RWL, or raised white letter, depending on the tire size selected. Those options are not evenly distributed across all three sizes, so the style choice is tied directly to the correct fitment.

A 735-14 buyer will be looking at blackwall or narrow whitewall BFGoodrich options, while F78-14 centers on a wide whitewall Coker Classic. F70-14 opens the door to the broadest performance-era sidewall mix, so owners chasing a stronger muscle-car look often begin by confirming whether that size is actually correct for their Challenger.

BFGoodrich, Coker Classic, Firestone, and Goodyear all offer tire options for the 1973 Dodge Challenger across its covered 14-inch bias-ply sizes. Brand availability depends on the specific tire size, with BFGoodrich covering 735-14, Coker Classic covering F78-14, and Firestone and Goodyear concentrated in F70-14.

That spread gives buyers different ways to approach the car’s final look. Someone replacing a 318 fitment may focus on a traditional whitewall or blackwall presentation, while a 340 V8 owner shopping F70-14 will have more room to compare series names and sidewall styles without stepping outside the proper size family.

A period-style 1973 Dodge Challenger tire choice starts with the correct primary size for the exact configuration, then narrows to the look the car is meant to carry. 735-14 and F78-14 support more traditional presentations, while F70-14 opens up a stronger muscle-era look through Firestone and Goodyear performance-style sidewall treatments.

For a restoration-oriented result, keeping the correct size family matters more than choosing the most eye-catching sidewall. Buyers aiming for exact historical authenticity should compare the tire choice against marque-specific references or original vehicle documentation, especially when selecting between whitewall, redline, pin stripe, or raised white letter styling.

Bias-ply construction plays a large role in the visual character of a restored 1973 Dodge Challenger because all primary fitments for this application are bias-ply 14-inch tires. That construction helps preserve the period sizing language and overall presentation associated with the car’s early-1970s look.

A radial equivalent can still be a valid option, especially when road use is a bigger priority, but it changes the path of the restoration decision. Owners trying to keep a more traditional visual impression often stay with bias-ply sizing, while those considering radials should pay close attention to profile, wheel width, and how the finished car is meant to be presented.

Yes, modifications can affect tire fitment on a 1973 Dodge Challenger even when the tire size itself is correct for the original application. Aftermarket wheels, suspension changes, altered ride height, or body and brake upgrades can all change the amount of space available around a 14-inch tire.

That is why the actual car should be checked before changing size or construction, especially on a Challenger with aluminum wheels or a non-stock stance. Wheel width, offset, steering clearance, and fender room all matter, and those details become even more important when comparing a bias-ply tire to a radial-equivalent alternative.

Before driving a 1973 Dodge Challenger on new tires, inspect the wheels for correct diameter and condition, confirm that the new size matches the car’s actual setup, and verify proper inflation. It also makes sense to look over suspension and steering components, since worn parts can affect how any new tire behaves on the road.

A collector-era car should also be checked for rubbing at full steering lock, visible contact under compression, and any signs of uneven wheel fitment from past modifications. A short, careful road test can help confirm that the Challenger tracks cleanly and that the tire clears the fender, chassis, and suspension through normal movement.

1973 Dodge Challenger tires should be maintained with regular pressure checks, routine visual inspection, and attention to age-related deterioration that can affect low-use collector cars. Sidewall cracking, bulges, cuts, tread separation, and slow air loss all deserve attention, whether the car runs a traditional bias-ply tire or a radial equivalent.

Storage conditions matter as much as mileage on an older vehicle. Keeping the Challenger away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and periodic inspections are smart even during off-season storage so the car is not returned to the road on tires that have aged out despite limited use.
