1968 Dodge Coronet Tires

The 1968 Dodge Coronet does not use one single tire size across every covered version. Primary fitments include 735-14, 775-14, 825-14, and F70-14, all in bias-ply construction on 14-inch rims. The exact size depends on the specific Coronet sub-model rather than on the model name alone.

That means the first step is identifying whether the car is a Coronet or Coronet R/T, a Coronet Wagon, or a Coronet w/440 Eng. After that, compare the wheel diameter already on the car and check whether it still has its original-style wheel setup, since aftermarket wheels or prior tire changes can complicate size selection.

The covered tire fitments for the 1968 Dodge Coronet all use a 14-inch rim diameter. That is true whether the car takes a numeric bias-ply size such as 735-14, 775-14, or 825-14, or the alphanumeric F70-14 size used on certain applications.

Rim diameter is only part of the fitment picture, so it is still important to confirm wheel width before choosing among available tires or considering a radial equivalent. On older Mopars, wheel changes over the years are common, and a 14-inch wheel does not automatically mean every 14-inch Coronet tire option is appropriate.

The 1968 Dodge Coronet covers several sub-models, and those configurations do not all share the same primary tire fitment. Coronet and Coronet R/T applications can use 735-14 or 775-14, the Coronet Wagon uses 825-14, and the Coronet w/440 Eng. can use 775-14 or F70-14.

That variation means tire choice starts with the exact version of the car, not just the year and model name. It also explains why some Coronets lean toward whitewall-oriented numeric sizes while others open the door to muscle-era alphanumeric tires with redline, pin stripe, or raised white letter styling.

F70-14 is a bias-ply primary tire size for the 1968 Dodge Coronet w/440 Eng. It uses the vintage alphanumeric sizing system rather than the earlier fully numeric pattern, but it remains a bias-ply fitment tied to a 14-inch wheel.

That matters because an F70-14 bias-ply tire gives the car a very different presentation from a modern radial, both visually and in construction. Anyone considering an alternative should verify wheel width, compare the intended tire's overall dimensions, and make sure steering and fender clearance remain appropriate for the car's actual setup.

Radial equivalents for 775-14 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 for these equivalents is 4 to 6 inches.

Those choices give different sizing conventions and profile styles rather than one universal answer. The bias-look radial is useful for buyers who want a more traditional visual presentation, while the metric and P-metric options follow more modern sizing systems. Any conversion still deserves a check of wheel width, diameter, and vehicle clearance.

Start by matching the Coronet's actual primary tire size to its approved radial-equivalent options, then confirm the 14-inch wheel diameter and the rim-width range tied to that equivalent. On this car, the correct equivalent depends on whether the original size is 735-14, 775-14, 825-14, or F70-14.

A careful conversion also means checking section width and overall dimensions against the car's current wheel, suspension, and body clearance. Older cars are often modified, so wheel offset, ride height, and prior brake or suspension changes can affect the result just as much as the nominal tire size printed on the sidewall.

A 775-14 choice starts with confirming that the car's sub-model actually uses that size, since not every 1968 Dodge Coronet does. From there, the main considerations are bias-ply construction, compatible wheel width, and the sidewall treatment that best matches the car's intended look, whether that means narrow whitewall, redline, goldline, or blueline.

This size also offers several brand and series options, including BFGoodrich, Firestone, and US Royal bias-ply designs. That makes 775-14 less about finding any tire in the size and more about choosing the right visual character and specification range for the way the car is restored, displayed, or driven.

Sidewall choices for the 1968 Dodge Coronet are broad and depend on the tire size. Across the available bias-ply options, styles include blackwall, narrow whitewall, redline, goldline, blueline, pin-white-stripe, and RWL raised white letter sidewalls.

Those appearance differences can change the personality of the car as much as the tire size itself, especially on a late-1960s Mopar. Numeric sizes tend to lean toward traditional blackwall and whitewall presentations, while F70-14 opens the door to more overt muscle-era styling cues. The right choice depends on the sub-model and the overall look being pursued.

The 1968 Dodge Coronet is served by BFGoodrich, Firestone, Goodyear, and US Royal, depending on the size being selected. Those brands appear across several bias-ply tire lines, including Silvertown Classic Bias Ply, Firestone Classic Bias Ply, Wide Oval, Custom Wide Tread, Speedway Wide Tread, and US Royal Classic Bias Ply.

Brand choice should be treated as part of the overall fitment and appearance decision rather than as a shortcut to the right tire. Some sizes have only a few options, while others, especially 775-14 and F70-14, offer a wider mix of sidewall treatments and series names that better support a particular restoration or muscle-era presentation.

A period-style 1968 Dodge Coronet usually starts with the correct primary bias-ply size for the exact sub-model, then narrows down by sidewall treatment and tire series. A wagon, standard Coronet, Coronet R/T, and Coronet w/440 Eng. do not all begin from the same fitment, so the visual direction should follow the correct size first.

After the size is confirmed, the choice becomes whether the car looks most appropriate with blackwall, narrow whitewall, redline, goldline, pin stripe, or raised white letter styling. When strict originality matters, marque-specific documentation and restoration references are worth checking before treating any particular sidewall treatment as historically exact for the car.

Tire construction changes the visual character of a restored 1968 Dodge Coronet as much as the sidewall style does. The primary fitments for this model are bias-ply tires, and that construction helps preserve the taller, more traditional profile and period presentation associated with late-1960s intermediate Mopars.

A radial equivalent can be useful when a buyer wants a different driving setup, but it also shifts the look into a more modern sizing language unless a bias-look radial is chosen where available. That is why appearance-focused restorations usually begin with the original size family and then compare construction only after the visual goal is clear.

Yes, modifications can affect tire fitment on a 1968 Dodge Coronet even when the tire size appears correct on paper. Wheel width, offset changes, suspension alterations, ride-height changes, and body or brake modifications can all influence whether a bias-ply tire or radial equivalent has the clearance the car needs.

That is especially important on a model with multiple original tire sizes, since a car may already be running a setup different from its original sub-model fitment. A quick check of wheel dimensions, steering travel, and fender clearance is worthwhile before mounting new tires, particularly if the car has been restored or modified over time.

Before driving a 1968 Dodge Coronet on new tires, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the tires are seated and inflated appropriately. It is also smart to check for suspension looseness, brake drag, and any interference that could appear at full steering lock or over bumps.

Collector cars often spend long periods parked, so the rest of the tire system matters as much as the fresh rubber. Look over valve stems, verify lug torque, and keep an eye on early air loss during the first drives. A short, cautious road test can reveal rubbing, pulling, or vibration before a longer trip.

Tires on a collector 1968 Dodge Coronet should be inspected regularly for cracking, bulges, cuts, uneven wear, and air loss, even if the car is driven only occasionally. Low-mileage use does not stop tires from aging, and bias-ply tires in particular deserve routine visual checks before each outing.

Proper storage also matters. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. During the season, maintain pressure consistently and move the car often enough to avoid long-term flat spotting. Any sign of deterioration should be evaluated before putting the car back on the road.
