The 1971 Plymouth Valiant & Duster sits squarely in Chrysler's compact-car era, when practical transportation and youthful performance flavor often shared the same showroom floor. These A-body Plymouths remain appealing because they can range from simple six-cylinder cruisers to sharper small-block street cars, and tire choice plays a big role in preserving that character. Primary fitment stays rooted in 14-inch bias-ply sizing, with 6.45-14, 695-14, and D78-14 all appearing across the covered configurations. Within those sizes, the real choices involve period-style sidewall treatments, tire series, and whether a 695-14 car should be evaluated against a modern radial equivalent. Start by confirming the exact engine-based sub-model and wheel setup before choosing for restoration appearance or road use.
Which Tire Size Is Right for The 1971 Plymouth Valiant & Duster
Three primary tire sizes apply to the 1971 Plymouth Valiant & Duster, and all of them are bias-ply fitments on 14-inch rims. The first step is identifying the exact engine-based sub-model, because tire size varies across the covered configurations. Once that is clear, the decision shifts to choosing the right period-style tire presentation, available brand and series options, and whether a 695-14 application should also be compared with radial-equivalent alternatives.
A 6.45-14 uses a numeric bias-ply size code in which 6.45 refers to the tire's nominal section width in inches and 14 identifies the wheel diameter. This is a traditional bias-ply fitment suited to the period driving character and appearance expected on an early-1970s compact Plymouth. Its relevance is mainly fitment-based, since this size appears on specific six-cylinder applications rather than across the full Valiant & Duster range. Choosing it starts with confirming that your particular sub-model actually uses 6.45-14 before comparing any wheel, clearance, or restoration-oriented considerations.
A 695-14 is a numeric bias-ply size, with 6.95 indicating nominal section width and 14 indicating a 14-inch rim. On the 1971 Plymouth Valiant & Duster, it is one of the key shared fitments and also the size with the broadest product choice, including BFGoodrich, US Royal, and Goodyear options. Available sidewall treatments include blackwall, narrow whitewall, dual redline, raised white letter, and Blue Streak styling across series such as Silvertown Classic Bias Ply, US Royal Classic Bias Ply, Blue Streak, and Power Cushion. This is the size to study most closely if you want the widest mix of appearance choices or want to compare a bias-ply tire with a radial equivalent.
D78-14 uses a vintage alphanumeric bias-ply size system, where the letter marks the tire's size class, the series number identifies the profile family, and 14 denotes wheel diameter. This is still a traditional bias-ply fitment, but the coding style is different from the older straight-numeric sizes used elsewhere in the lineup. Its role is configuration-specific, appearing on certain 225 and 318 engine applications rather than every 1971 Plymouth Valiant & Duster. The right reason to choose D78-14 is simple accuracy for the vehicle's actual setup, followed by careful confirmation of wheel and sub-model fitment.
Tire fitment for the 1971 Plymouth Valiant & Duster is not completely uniform, because the covered sub-models split across different 14-inch bias-ply sizes. Checking the exact engine-based sub-model matters first, especially since 695-14 overlaps both groups while 6.45-14 and D78-14 do not.

The 1971 Plymouth Valiant & Duster 6 Cyl. w/198 Eng. uses 14-inch bias-ply sizing, with 6.45-14 and 695-14 associated with this configuration. That makes the selection process less about broad model-year assumptions and more about confirming which wheel and period-style presentation best match the individual car.
The 1971 Plymouth Valiant & Duster w/225 & 318 Eng. uses 14-inch bias-ply fitments as well, but here the associated sizes are 695-14 and D78-14. This setup calls for careful size confirmation before purchase, especially if the goal is to balance correct-looking stance, wheel compatibility, and the available sidewall choices in 695-14.
Bias-Ply to Radial Tire Conversion for the 1971 Plymouth Valiant & Duster
For the original 695-14 size, three radial-equivalent options are available. 175R14 is the 80-series metric radial equivalent, P185/75R14 is the P-metric 75-series radial equivalent, and P195/70R14 is the P-metric 70-series radial equivalent. These choices reflect different sizing conventions and profile families rather than one automatic substitute. A recommended rim-width range of 4 to 6 inches applies, and any conversion should still be checked against the car's wheel dimensions, overall setup, and clearance.

Tire Size & Fitment
What tire size fits a 1971 Plymouth Valiant & Duster?
The 1971 Plymouth Valiant & Duster uses three primary tire sizes: 6.45-14, 695-14, and D78-14. All three are bias-ply fitments on 14-inch rims, but they do not apply equally across every covered configuration. The 6 Cyl. w/198 Eng. sub-model uses 6.45-14 and 695-14, while the w/225 & 318 Eng. sub-model uses 695-14 and D78-14.
That means the first step is confirming the exact engine-based sub-model and checking what wheels are actually on the car today. Many surviving A-body Plymouths have seen wheel or suspension changes over the years, so choosing by model name alone can lead to the wrong size. Once the correct fitment is confirmed, selection becomes a matter of construction style, sidewall appearance, and whether a 695-14 application should also be compared with radial-equivalent options.
What size rim does a 1971 Plymouth Valiant & Duster use?
The covered tire fitments for the 1971 Plymouth Valiant & Duster all use a 14-inch rim diameter. That includes 6.45-14, 695-14, and D78-14, so the rim diameter remains consistent even though the tire sizes vary by sub-model. The key difference is the tire size itself, not a change from one wheel diameter to another.
Rim diameter is only one part of the fitment picture, so it should not be the sole basis for choosing a tire. Wheel width can still affect which tire works properly, and a car with replacement wheels may not match its original-type setup anymore. Confirm the wheel dimensions before ordering, especially if the car has been modified or if a radial equivalent is being considered for a 695-14 application.
Why does the 1971 Plymouth Valiant & Duster have more than one tire size?
More than one tire size appears because the 1971 Plymouth Valiant & Duster covers different engine-based sub-models. The 6 Cyl. w/198 Eng. configuration is associated with 6.45-14 and 695-14, while the w/225 & 318 Eng. configuration is associated with 695-14 and D78-14. The overlap at 695-14 makes it common, but the other sizes are tied to more specific applications.
This matters because the right tire is determined by the car's exact configuration rather than by a one-size-fits-all model-year answer. It also means a buyer should verify the current wheels and compare the tire already on the car before making a final choice. That extra step is especially important on collector vehicles that may have changed owners, wheels, or driveline combinations long ago.
Bias-Ply & Radial Options
Is 695-14 a bias-ply or radial tire for the 1971 Plymouth Valiant & Duster?
On the 1971 Plymouth Valiant & Duster, 695-14 is a primary bias-ply tire size. The available 695-14 products are bias-ply designs, and that keeps this size rooted in the traditional construction used across the covered vehicle fitments. It is one of the main sizes for this application and appears across both engine-based sub-model groupings.
That distinction matters because a bias-ply tire preserves the period-style construction and appearance many owners want from an early-1970s Plymouth. A buyer comparing options in 695-14 is mainly choosing among sidewall styles, series, and brands unless a radial equivalent is being considered separately. Construction changes should be treated as a fitment decision, not just a cosmetic one, since wheel compatibility and overall vehicle setup still need to be checked.
What radial tire sizes are equivalent to 695-14?
Radial equivalents for 695-14 include 175R14 as an 80-series metric radial, P185/75R14 as a P-metric 75-series radial, and P195/70R14 as a P-metric 70-series radial. These are three distinct radial-equivalent paths for the same original bias-ply size, and they represent different sizing systems rather than one single replacement format.
A recommended rim-width range of 4 to 6 inches is associated with those 695-14 equivalents, which makes wheel measurement worth checking before any change in construction. The next step is comparing the car's actual wheels, available clearance, and intended use so the alternative size stays appropriate for the vehicle. Equivalent does not mean automatic interchangeability, especially on an older compact that may no longer be on its original wheels.
Should I use bias-ply or radial tires on a 1971 Plymouth Valiant & Duster?
That decision depends on what size your car uses and what you want from the finished setup. The primary fitments for the 1971 Plymouth Valiant & Duster are bias-ply, and 695-14 is the size with radial-equivalent options. If preserving a traditional period-style presentation is the priority, staying with the primary bias-ply fitment often aligns more closely with that goal.
A radial alternative can still be worth considering on a 695-14 application, but the wheel dimensions and vehicle clearance should be confirmed before making that change. It also helps to think about how the car will be used, whether mostly for shows, occasional cruises, or broader road mileage. Matching the tire choice to the car's actual setup usually matters more than choosing one construction type on principle.
Choosing the Right Tire
What should I consider when choosing a 695-14 tire for a 1971 Plymouth Valiant & Duster?
Start with fitment accuracy, because 695-14 is common on the 1971 Plymouth Valiant & Duster but not universal to every covered configuration. Then compare the available bias-ply choices by brand, tire series, sidewall style, rim-width specification, weight, and maximum load rating. In this size, BFGoodrich, US Royal, and Goodyear each offer distinct period-style presentations.
A blackwall, narrow whitewall, dual redline, or raised white letter design can change the car's look as much as the brand name itself. It also helps to think about whether the car is being restored toward a restrained stock-style appearance or a more performance-flavored presentation. Once those priorities are clear, the product grid becomes much easier to narrow down without drifting away from the correct size.
What sidewall styles are available for 1971 Plymouth Valiant & Duster tires?
In the available 695-14 product selection for the 1971 Plymouth Valiant & Duster, sidewall styles include blackwall, narrow whitewall, dual redline, raised white letter, and a raised-white-letter Blue Streak style. Those choices all stay within the same primary 14-inch bias-ply size, but they create very different visual results on the car.
Sidewall style is often the easiest way to tune the personality of a Valiant or Duster without changing the basic fitment. A narrow whitewall can suit a more restrained period presentation, while dual redlines or raised white lettering push the car toward a sportier look. Appearance should still come after size confirmation, since the right visual treatment only works when the tire also matches the car's actual sub-model and wheel setup.
What brands offer tires for the 1971 Plymouth Valiant & Duster?
The available 695-14 fitment options for the 1971 Plymouth Valiant & Duster come from BFGoodrich, US Royal, and Goodyear. Those brands appear across several bias-ply series, including Silvertown Classic Bias Ply, US Royal Classic Bias Ply, Blue Streak, and Power Cushion. The result is a solid spread of traditional-looking tires within one of the key primary sizes.
Brand should be considered alongside the rest of the tire's character rather than as a standalone decision. One product may match the visual goal better because of its sidewall treatment, while another may align more closely with the type of driving the car sees. Looking at the full combination of size, construction, series, and appearance is usually more useful than narrowing the choice by brand name first.
Restoration & Appearance
Which tire should I choose for a period-style 1971 Plymouth Valiant & Duster?
A period-style choice starts with using the correct primary size for the car's exact configuration, whether that is 6.45-14, 695-14, or D78-14. On a 695-14 application, the available bias-ply offerings make it possible to stay close to the visual character expected of an early-1970s compact Plymouth while still choosing among different brands and series.
From there, the right selection depends on the look being restored. A simple blackwall gives a restrained presentation, while narrow whitewalls, dual redlines, or raised white letters can shift the appearance in noticeably different directions. If exact originality matters beyond general period style, compare the car against marque references, build documentation, or well-vetted restoration examples before choosing a final sidewall treatment.
How does tire construction affect the appearance of a restored 1971 Plymouth Valiant & Duster?
Tire construction influences both stance and visual character, especially on a compact car from 1971. The primary fitments for the Plymouth Valiant & Duster are bias-ply, so staying with a bias-ply tire generally preserves the traditional look associated with the car's original-era presentation. That is particularly relevant when the goal is a restoration-oriented finish rather than a modernized driver setup.
A radial equivalent is only part of the conversation and applies specifically to 695-14, not every fitment on the page. Even when a radial is being considered, the visual effect may differ from a traditional bias-ply setup, so appearance should be weighed alongside wheel compatibility and clearance. Restored cars often look most cohesive when tire construction supports the same overall era-specific theme as the wheels and ride height.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1971 Plymouth Valiant & Duster?
Yes, modifications can change tire fitment on a 1971 Plymouth Valiant & Duster even when the car originally used one of the correct 14-inch bias-ply sizes. Aftermarket wheels, wheel-width changes, suspension work, altered ride height, or brake conversions can all influence what clears properly. That matters most when comparing the car's current setup against its original-type tire sizing.
A modified car should be measured rather than assumed to match stock-style fitment. Wheel diameter may still be 14 inches, but width and offset can change how a tire sits in the wheel opening or turns at full steering lock. Extra caution is worthwhile when considering a 695-14 radial equivalent, since the correct comparison involves the actual wheel and clearance conditions on the vehicle today.
What should I inspect before driving a 1971 Plymouth Valiant & Duster on new tires?
Before road use, inspect the wheel condition, verify the wheel dimensions, and make sure the new tires match the car's correct size and construction plan. On the tires themselves, check inflation, bead seating, sidewall condition, and any signs of shipping or installation damage. A collector-era Plymouth also deserves a quick look at suspension, steering, and brake condition before a serious drive.
The first miles are a good time to watch for rubbing, pull, vibration, or unusual clearance issues during turns and over bumps. Those symptoms can point to wheel mismatch, alignment concerns, or an older chassis component that needs attention. A careful road check matters even more if the car has sat for long periods, changed hands recently, or moved away from its previous tire and wheel combination.
How should 695-14 tires on a collector 1971 Plymouth Valiant & Duster be maintained?
Collector-car tires in 695-14 should be maintained with regular pressure checks, periodic visual inspections, and storage habits that reduce age-related deterioration. Look for cracking, bulges, cuts, uneven wear, and slow air loss, especially on a Plymouth that spends more time parked than driven. Keeping the car clean and stored away from prolonged heat, strong sunlight, and ozone sources also helps protect the tires.
Low annual mileage does not eliminate the need for inspection, because age and storage conditions matter as much as tread depth on an older hobby vehicle. Rolling the car occasionally and checking for flat spotting can also be useful on lightly used bias-ply tires. Before a longer trip, confirm pressure again and give the full tire and wheel package another close review rather than assuming a seldom-driven car is road-ready.
