1979 Dodge Ramcharger Tires

A 1979 Dodge Ramcharger can use FR78-15, HR78-15, LR78-15, 700-15, L78-15, or 10-15, depending on the exact GVWR or sub-model. Those fitments include both radial and bias-ply construction, and all of them are built around a 15-inch rim diameter.

The important part is that Ramcharger fitment is configuration-specific rather than universal across the model line. Before choosing a tire, match the truck's exact GVWR or named sub-model, then confirm the wheels currently on the vehicle if it has been modified over the years.

The tire fitments covered for the 1979 Dodge Ramcharger all use a 15-inch rim diameter. That applies across the radial sizes FR78-15, HR78-15, and LR78-15, as well as the bias-ply sizes 700-15, L78-15, and 10-15.

Rim diameter is only the starting point, because wheel width still matters when comparing actual tire choices. A truck may still wear 15-inch wheels but have aftermarket rims that change width or offset, so it is wise to verify the wheel itself before selecting a replacement tire.

The 1979 Dodge Ramcharger covers multiple GVWR classifications and special configurations, so the tire size is not the same across every version. Some sub-models use radial sizes such as FR78-15, HR78-15, or LR78-15, while others use bias-ply sizes including 700-15, L78-15, or 10-15.

That variation means the right tire cannot be chosen by year, make, and model alone. The buyer should first pin down the exact Ramcharger configuration, then confirm whether the truck still has its original wheel setup or has been changed to something different during its life.

L78-15 is a primary bias-ply tire size for the 1979 Dodge Ramcharger. It appears in bias-ply product form across several series and sidewall treatments, and it also has separate radial-equivalent sizes that can be considered as alternatives.

That distinction matters because keeping L78-15 in bias-ply form preserves the original sizing format and a traditional construction style. Moving to a radial equivalent changes the construction choice, so the wheel width, overall vehicle setup, and intended driving use should all be reviewed before making the switch.

Radial equivalents for L78-15 include 235R15, P235/75R15, P255/70R15, and 820R15. Those represent an 80-series metric radial, a P-metric 75-series radial, a P-metric 70-series radial, and a bias-look radial equivalent, respectively.

Each one approaches the original L78-15 fitment a little differently in sizing convention and visual character. The recommended rim-width range is 6 to 8 inches, and any equivalent should still be checked against the truck's wheel dimensions, suspension condition, and available fender and steering clearance.

That depends on the exact Ramcharger configuration and what you want from the truck. Some 1979 Ramcharger applications use primary radial sizes such as FR78-15, HR78-15, or LR78-15, while others use primary bias-ply sizes such as 700-15, L78-15, or 10-15.

A restoration-minded owner may want to stay with the original construction type for that specific sub-model, while a road-use buyer may consider a radial-equivalent path where one exists. The safest approach is to start with the correct primary fitment, then evaluate wheel compatibility and overall vehicle condition before changing construction.

Start by confirming that 700-15 is the correct primary size for the specific 1979 Dodge Ramcharger sub-model. Within that size, the choices vary by brand, sidewall style, tire series, and intended character, including passenger-style whitewall tires as well as more truck- and military-oriented blackwall designs.

The practical decision comes down to how the Ramcharger will be presented and used. A restoration-oriented truck may lean toward a traditional whitewall bias-ply, while a utility-focused truck may call for a more rugged blackwall series, so wheel width and use expectations should guide the final comparison.

Sidewall choices for 1979 Dodge Ramcharger tires include blackwall, narrow whitewall, wide whitewall, and dual-white-stripe styles, depending on the tire size selected. Those appearance options are concentrated mainly in 700-15, L78-15, and LR78-15 offerings rather than across every size on the page.

That means sidewall selection starts with the correct fitment, not the appearance alone. Once the size and construction are confirmed, the buyer can decide whether the truck looks better with a plainer work-truck presentation, a more upscale whitewall treatment, or a vintage radial look.

1979 Dodge Ramcharger tire options include Firestone, BFGoodrich, Coker Classic, and STA. Brand availability depends on the exact size, with 700-15 and L78-15 offering the broadest mix of choices and LR78-15 carrying a Firestone bias-look radial option.

Brand names are useful, but they should be compared alongside size, construction, sidewall treatment, and tire series rather than by label alone. A Ramcharger buyer usually gets the best result by narrowing the correct fitment first, then comparing the visual style and intended use of each available option.

A period-style 1979 Dodge Ramcharger tire choice starts with the exact primary size and construction for the truck's sub-model. That could mean a vintage alphanumeric radial such as HR78-15 or LR78-15, or a bias-ply truck fitment such as 700-15 or L78-15 depending on the configuration.

Once the correct fitment is confirmed, appearance decisions can focus on blackwall, narrow whitewall, wide whitewall, or other available vintage-style presentations. If exact restoration accuracy matters, it is worth checking model-specific historical references or marque guidance before settling on a particular sidewall treatment.

Tire construction changes the visual character of a restored 1979 Dodge Ramcharger more than many buyers expect. A bias-ply tire usually supports a more traditional truck-era presentation, while a vintage-style radial or bias-look radial can give the vehicle a later-period roadgoing look without using a modern-looking metric tire.

That visual difference is especially important on a Ramcharger because the model spans both bias-ply and radial primary fitments. The right approach is to match the truck's actual configuration first, then choose the construction that best supports the restoration goal and the way the vehicle will be driven.

Yes, modifications can change how a tire works on a 1979 Dodge Ramcharger even when the nominal size looks correct. Aftermarket wheels, changes in wheel width or offset, suspension lifts, lowering, or body alterations can all affect clearance and how a vintage tire sits on the vehicle.

That is especially important on a Ramcharger because several different 15-inch fitments already exist across the model range. If the truck has been changed from its original setup, check wheel dimensions, steering clearance, and fender space before choosing a replacement based only on the original size designation.

Before putting a 1979 Dodge Ramcharger back on the road, inspect the wheels for damage, confirm the correct rim diameter and width, and make sure the tires are mounted in the proper size for the exact configuration. It also helps to verify inflation, look over valve stems, and check for any obvious rubbing points.

A truck that has sat for long periods deserves an extra look at suspension wear, steering play, and brake condition because those issues can affect how new tires behave. A short, careful test drive can reveal clearance or handling concerns before the Ramcharger is used for longer highway or trail miles.

700-15 tires on a collector 1979 Dodge Ramcharger should be kept properly inflated, inspected regularly for cracking, bulges, cuts, or uneven wear, and checked for air loss between drives. Collector vehicles often spend long periods parked, so tire condition matters just as much as remaining tread depth.

Storage also plays a role in long-term health. Keeping the Ramcharger away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the sidewalls, and occasional movement can reduce flat-spotting during long storage periods. Any tire showing age-related deterioration should be evaluated before road use.
