1970 Plymouth Valiant & Duster Tires

The 1970 Plymouth Valiant & Duster uses four primary bias-ply tire sizes: 695-14, C78-14, D78-14, and E70-14. The correct size depends on the vehicle's covered configuration, with 6 Cyl. applications using 695-14 or C78-14 and w/318 Eng. w/Air applications using D78-14 or E70-14.

That means the first job is identifying the exact sub-model and confirming what is actually on the car today. All of these sizes fit 14-inch rims, but they are not interchangeable by name alone. A car with replacement wheels, old sidewall lettering, or previous owner changes should have its wheel width and tire clearance checked before selecting a replacement.

Every primary tire size used on the 1970 Plymouth Valiant & Duster in this fitment group is built around a 14-inch rim diameter. That includes the numeric bias-ply 695-14 and the alphanumeric bias-ply sizes C78-14, D78-14, and E70-14.

Rim diameter is only one part of the fitment picture, so it helps to confirm wheel width before ordering tires, especially if the car no longer has its original wheels. Product specifications within these sizes can call for different width ranges, and that becomes particularly important when comparing smaller six-cylinder fitments to the larger V8 and air-conditioned applications.

More than one tire size appears on the 1970 Plymouth Valiant & Duster because the fitment changes by covered sub-model. Six-cylinder versions use 695-14 or C78-14, while the w/318 Eng. w/Air configuration moves to D78-14 or E70-14, even though all remain bias-ply tires for 14-inch wheels.

That variation matters because an older compact often carries whatever was easiest to mount over the years, not necessarily the correct size for its configuration. Matching the tire to the car's exact setup helps preserve proper proportions and avoids choosing a size simply because it shares the same wheel diameter. Checking current wheel width is also worthwhile before settling on a replacement.

For the 1970 Plymouth Valiant & Duster, 695-14 is a primary bias-ply tire size. It uses an older numeric sizing system rather than a modern metric radial format, and it belongs to the traditional 14-inch fitment family used on covered six-cylinder applications.

That matters because keeping a bias-ply construction preserves the original-style sizing format and traditional look, while moving to a radial means evaluating an equivalent rather than another primary 695-14 fitment. Buyers considering that change should compare the actual wheel width, overall tire proportions, and clearance around steering and suspension components before switching construction types.

Radial equivalents for 695-14 are 175R14 as an 80-series metric radial, P185/75R14 as a 75-series P-metric radial, and P195/70R14 as a 70-series P-metric radial. A recommended rim-width range of 4-6 inches applies to those equivalent choices.

These alternatives give different sizing conventions rather than another primary bias-ply fitment, so the decision is partly about how modern or traditional the tire format should look on the car. Wheel width, section fit, and body clearance still need to be checked on the actual vehicle, especially if the Valiant or Duster has replacement wheels or suspension changes from stock height.

Start by matching the car's primary bias-ply size to the correct radial equivalent family, then confirm that the wheel diameter and wheel width suit the radial size being considered. On this application, radial equivalents are available for 695-14, C78-14, and E70-14, but the conversion should still be treated as a fitment change that needs verification.

A careful check should include actual wheel width, fender and steering clearance, suspension condition, and any modifications that may affect space around the tire. It also helps to compare the look you want from the car, since a modern radial profile can change the visual character even when the size relationship is appropriate for road use.

Choosing a 695-14 tire starts with confirming that the car is one of the covered six-cylinder applications using that primary size. Once the size is correct, the key differences are brand, tire series, sidewall treatment, and rim-width specification, with choices that include blackwall, narrow whitewall, dual redline, and raised white letter presentations.

The right pick depends on how the car is being used and how original-looking or sporty the finished appearance should be. A restoration-oriented car may lean toward a traditional whitewall or blackwall look, while a period performance presentation may point toward redline or raised white letter styling. Wheel width should still be checked against the tire's specification before final selection.

Sidewall choices for the 1970 Plymouth Valiant & Duster include blackwall, narrow whitewall, dual redline, redline, pin white stripe, raised white letter, and raised white letter with blue streak styling. The exact sidewall styles depend on the tire size, with 695-14 and E70-14 showing the broadest visible variety among the available products.

That makes sidewall treatment one of the biggest appearance decisions on this page. Smaller compact-car styling cues may look more natural with blackwall or narrow whitewall, while muscle-era visual themes often lead buyers toward redline or raised white letter tires. Sidewall style should be chosen only after confirming the car's actual size and wheel setup, since appearance does not override fitment.

Available brands for the 1970 Plymouth Valiant & Duster include BFGoodrich, US Royal, Goodyear, and Firestone. Brand availability depends on size, with 695-14 covered by BFGoodrich, US Royal, and Goodyear choices, while E70-14 includes Firestone and Goodyear options across period-style bias-ply series.

The best way to use that brand variety is to compare each tire within the correct size rather than starting with the brand name alone. Series, sidewall design, rim-width specification, and overall presentation can vary meaningfully within the same size. Once the sub-model and tire code are confirmed, the comparison becomes much clearer and more useful.

A period-style 1970 Plymouth Valiant & Duster starts with using the correct primary bias-ply size for the car's sub-model, whether that is 695-14, C78-14, D78-14, or E70-14. From there, the most appropriate choice usually comes down to the visual character you want, such as blackwall, whitewall, redline, pin white stripe, or raised white letter styling.

The car's intended personality matters here. A restrained commuter-style restoration may suit blackwall or narrow whitewall, while a more aggressive Duster presentation may lean toward redline or raised white letter tires. When exact originality is important, it is wise to compare the car against period photos, marque references, or build-specific documentation before settling on one sidewall treatment.

Tire construction affects both the look and the stance of a restored 1970 Plymouth Valiant & Duster because the primary fitments are bias-ply sizes with older numeric or alphanumeric sidewall language. Keeping a bias-ply tire maintains that traditional visual presentation more naturally than a modern metric radial code on the sidewall.

That does not mean a radial equivalent cannot work for a driver-focused restoration, but it does change the visual impression of the car. Buyers who want a stronger original-era appearance usually begin with the proper bias-ply size and then choose the sidewall treatment that suits the build. A radial alternative should be chosen with both aesthetics and wheel compatibility in mind.

Yes, modifications can affect tire fitment on a 1970 Plymouth Valiant & Duster even when the tire size is otherwise correct for the covered application. Aftermarket wheels, different wheel widths, suspension lowering, spring changes, and body or brake alterations can all change the space available for a 14-inch tire.

That is especially important on older compact cars that may have changed owners and parts many times. A tire that matches the correct size code still needs enough room at full steering lock and through normal suspension movement. Measuring the current wheel setup and checking clearances before mounting helps prevent rubbing issues and preserves the intended look of the car.

Before driving a 1970 Plymouth Valiant & Duster on new tires, inspect wheel condition, verify the wheel diameter and width, and make sure the tires are mounted in the correct size for the car's sub-model. It is also smart to look over valve stems, lug hardware, and basic suspension components that can affect ride height or clearance.

Once the car is on the ground, check inflation, steering clearance, and visible space around the tire at the fender and suspension. A short, careful test drive can help reveal rubbing, pull, or vibration before the car goes on a longer trip. Rechecking air pressure and fastener torque after initial use is a sensible follow-up step.

Collector-car 695-14 tires should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Even when tread wear is low, an older-use 1970 Plymouth Valiant & Duster can develop issues from age, sunlight, moisture, ozone exposure, or long stationary periods that create flat spotting and sidewall deterioration.

Routine inspections should look for cracking, bulges, cuts, irregular wear, and slow air loss before the car is driven. It also helps to move the car periodically and keep it out of prolonged heat or direct sun when stored. Maintenance becomes more important on a low-mileage collector vehicle because time and environment can matter as much as mileage.
