1972 Plymouth Valiant & Duster Tires

The 1972 Plymouth Valiant & Duster uses three primary bias-ply tire sizes: 6.45-14, 695-14, and D78-14. All three are 14-inch fitments, but they do not apply uniformly across every covered engine configuration. The 198 and 225 engine version uses 6.45-14 and 695-14, while the 318 engine version uses 695-14 and D78-14.

That means the first step is confirming the exact engine-based sub-model and the wheel setup currently on the car. Many surviving Valiant and Duster vehicles have had wheels or tires changed over time, so the size mounted today may not tell the whole story. Matching the correct primary size is the starting point, then sidewall style, brand, and any radial-equivalent consideration can be narrowed down from there.

The tire sizes used on the 1972 Plymouth Valiant & Duster are built around a 14-inch rim diameter. That applies across 6.45-14, 695-14, and D78-14, so the covered fitments stay within one wheel diameter even though tire size can vary by engine grouping.

Rim diameter is only part of the fitment picture, especially on cars that may have seen decades of parts changes. Wheel width still matters when comparing products or considering a radial equivalent, and 695-14 radial alternatives carry a recommended rim-width range of 4 to 6 inches. Checking the actual wheel before ordering helps avoid choosing a tire that suits the diameter but not the wheel width or overall vehicle setup.

More than one tire size appears because the 1972 Plymouth Valiant & Duster fitment changes by engine-based sub-model. The 198 and 225 engine version uses 6.45-14 and 695-14, while the 318 engine version uses 695-14 and D78-14. The shared size between the two is 695-14, but the second listed size differs.

For a buyer, that means tire selection should not start with the model name alone. It should start by confirming whether the car is the 198 and 225 engine configuration or the 318 engine configuration, then verifying what is on the car now. That process is especially important if the car has aftermarket wheels, replacement wheels, or a long restoration history that may have altered the original combination.

On the 1972 Plymouth Valiant & Duster, 695-14 is a primary bias-ply tire size. Available 695-14 products on this application are bias-ply tires, and that construction is consistent with the original-style fitment approach used across the vehicle's listed sizes.

That matters because keeping a bias-ply tire preserves the sizing format and traditional presentation associated with the car. A buyer comparing alternatives should separate the primary bias-ply fitment from modern radial-equivalent options rather than treating them as the same thing. Once the correct size is confirmed, the next choice becomes whether the goal is a bias-ply look and feel or a radial alternative that still needs wheel and clearance checks.

Radial equivalents for 695-14 include 175R14, P185/75R14, and P195/70R14. The 175R14 is an 80-series metric radial equivalent, P185/75R14 is a P-metric 75-series radial equivalent, and P195/70R14 is a P-metric 70-series radial equivalent. No bias-look radial equivalent is associated with 695-14 here.

Each of those alternatives uses a different radial sizing convention, so the choice is not only about construction but also about profile family and wheel compatibility. A recommended rim-width range of 4 to 6 inches is tied to these equivalents. Before moving from the original bias-ply size to any radial alternative, compare the wheel width on the car and make sure steering, suspension, and body clearance are still appropriate.

Start by confirming that the car uses the 695-14 size, since that is the primary size on this application with stated radial equivalents. The available radial-equivalent sizes are 175R14, P185/75R14, and P195/70R14, with a recommended rim-width range of 4 to 6 inches for the equivalent fitment path.

The practical checks include actual wheel width, rim diameter, and clearance through steering and suspension movement. A surviving Valiant or Duster may also have replacement wheels, changed ride height, or prior repairs that alter available space. Comparing the tire already on the car against the intended radial size helps keep the conversion grounded in the vehicle's real setup rather than the model name alone.

Begin with the fact that 695-14 is a primary 14-inch bias-ply fitment used across both covered engine groupings of the 1972 Plymouth Valiant & Duster. From there, selection comes down to the tire's intended role on the car: traditional restoration-style appearance, a more performance-oriented visual treatment, or a baseline blackwall presentation.

Available 695-14 products vary by brand, tire series, sidewall style, rim-width specification, weight, and load rating. Some list 5.00 to 6.00-inch rim compatibility, while others are tied to 5-inch or 5.5-inch wheel widths. Comparing the actual wheel on the car with those product details is just as important as choosing between whitewall, dual-redline, raised white letter, or blackwall appearance.

Within the available 695-14 products for the 1972 Plymouth Valiant & Duster, sidewall choices include blackwall, narrow whitewall, dual-redline, RWL, and raised-white-letter blue streak styling. Those options all stay within the same primary tire size, but they give the car very different visual character depending on whether the goal is understated, sporty, or more restoration-oriented.

Appearance should be matched to the personality of the specific car rather than treated as a simple style upgrade. A plain Valiant can look more reserved on blackwalls or narrow whitewalls, while a Duster or 318-powered car may suit dual-redlines or raised white letters better. The key is choosing a sidewall treatment after confirming the right size and wheel, not before.

For the 695-14 size used on the 1972 Plymouth Valiant & Duster, available brands include BFGoodrich, US Royal, and Goodyear. Those brands appear across several tire series, including Silvertown Classic Bias Ply, US Royal Classic Bias Ply, Blue Streak, and Power Cushion, giving the buyer more than one way to approach period-style replacement.

Brand choice should be considered alongside size, series, sidewall treatment, and wheel compatibility rather than in isolation. Some products emphasize a cleaner stock-style look, while others carry more overt performance-era visual cues such as raised white letters or blue streak treatment. The better comparison is not brand versus brand alone, but how each available tire suits the specific Valiant or Duster build and intended use.

A period-style approach starts with the correct primary bias-ply size for the exact 1972 Plymouth Valiant & Duster configuration: 6.45-14, 695-14, or D78-14 depending on the engine grouping and wheel setup. Staying within those original-style sizing formats preserves the visual proportions and sidewall character that suit an early 1970s compact Mopar.

After the size is settled, the appearance choice usually comes down to sidewall treatment and tire series, especially within 695-14 where the product range is broad. Buyers pursuing close historical authenticity should compare their choice against marque references, surviving examples, or restoration documentation for the specific car. That helps separate a convincing period-style presentation from a tire that is only generally vintage in appearance.

Tire construction changes more than ride feel on a restored 1972 Plymouth Valiant & Duster; it also changes the visual impression of the car. The listed primary fitments are bias-ply sizes, and bias-ply tires generally preserve the older sizing language and traditional sidewall presentation associated with the model's era.

A radial alternative in the 695-14 equivalent range can still be a useful option, but it tends to move the car away from a strictly original-style presentation. That does not make it wrong; it simply means the buyer should decide whether appearance or driving preference leads the project. On a restoration-minded car, construction choice should be made as deliberately as paint, wheel covers, or trim details.

Yes, modifications can affect tire fitment on a 1972 Plymouth Valiant & Duster even when the nominal tire size is correct. Aftermarket wheels, changed wheel widths, altered offsets, suspension work, or ride-height changes can all influence how a 14-inch bias-ply or radial-equivalent tire sits in the wheel opening and clears surrounding components.

That is especially important when considering 695-14 radial equivalents such as 175R14, P185/75R14, or P195/70R14, because changing construction often changes the overall fitment conversation. A smart check includes wheel diameter, wheel width, lock-to-lock steering clearance, and fender or suspension space. Cars that have been modified over time should be evaluated by their actual setup, not only by catalog year and model.

Before driving a 1972 Plymouth Valiant & Duster on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware is proper, and verify inflation matches the tire's needs. The tires themselves should be checked for proper seating and uniform clearance at the fender, suspension, and steering components.

A collector-era car also deserves a broader look before road use. Steering and suspension wear, weak shocks, sagging springs, and old alignment issues can make a newly mounted set feel wrong even when the tire choice is sound. A short local drive followed by a second inspection for rubbing, air loss, or unusual wear is a sensible final step before any longer trip.

695-14 tires on a collector 1972 Plymouth Valiant & Duster should be maintained with regular pressure checks, visual inspections, and periodic evaluation for age-related deterioration. Even a low-mileage car can develop sidewall cracking, flat spotting, cuts, or slow air loss simply from long storage and infrequent use rather than from high road mileage.

Storage conditions matter as much as driving habits. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tire over time. It also helps to inspect tread and sidewalls before each outing and after extended storage. On a car that sees only occasional use, tire condition should be judged by age and health, not just by how much tread remains.
