The 1967 Plymouth Valiant sits squarely in the practical compact-car era, when simple engineering, tidy proportions, and durable everyday transportation made cars like this a familiar part of American roads. Today, surviving Valiants are often appreciated for that honest character, whether preserved as stock family transportation or restored as a clean Mopar compact. Tire fitment centers on two 13-inch bias-ply sizes, 650-13 and 700-13, with size choice tied to engine and air-conditioning configuration. Period-style options include different whitewall presentations, and modern radial equivalents are also available for owners considering a change in construction. The right choice starts with confirming the exact sub-model and wheel setup already on the car.
Which Tire Size Is Right for The 1967 Plymouth Valiant
The 1967 Plymouth Valiant uses two primary tire sizes, both bias-ply and both built for 13-inch rims. The first step is identifying the exact sub-model, because some 6-cylinder cars can use either 650-13 or 700-13, while 8-cylinder cars and all models with air conditioning use 700-13. Once the size is confirmed, the decision shifts to sidewall style, brand, and whether to stay with bias-ply construction or compare a radial equivalent.
In a numeric bias-ply size like 650-13, the 650 refers to an approximate 6.50-inch nominal section width and the 13 identifies the wheel diameter in inches. On the 1967 Plymouth Valiant, this is a traditional bias-ply fitment that suits the compact car's original-era tire presentation. Available choices include Coker Classic and US Royal versions in both wide whitewall and narrow whitewall form, all in classic bias-ply series. This size is worth considering when your specific Valiant configuration uses it and you want a period-style 13-inch tire with traditional proportions.
The 700-13 code is also a numeric bias-ply size, with the leading number indicating an approximate 7.00-inch nominal section width and the final number identifying a 13-inch rim. For the 1967 Plymouth Valiant, this size is especially important because it covers 8-cylinder cars and all models equipped with air conditioning. Firestone offers this size in a classic bias-ply series with a wide whitewall treatment, giving buyers a traditional look on the proper rim diameter. It is the size to evaluate when the car's configuration calls for the broader 13-inch bias-ply fitment.
Sub-model fitment matters on the 1967 Plymouth Valiant because tire size is not the same across every configuration. The key distinction is whether the car is a 6-cylinder version or an 8-cylinder or air-conditioned model, since that determines which 13-inch bias-ply size should be matched to the car.

The 1967 Plymouth Valiant 6 Cyl. can use either 650-13 or 700-13 in bias-ply construction on a 13-inch rim. That makes wheel confirmation especially important, along with deciding whether the goal is a slimmer period-style fitment or a larger original-size option for the specific setup already on the car.
The 1967 Plymouth Valiant 8 Cyl. & All Models w/Air uses the 700-13 bias-ply size on a 13-inch rim. Tire selection here is more straightforward, with the main decision shifting from size to choosing the right construction approach, sidewall appearance, and overall presentation for a restored or regularly driven car.
Bias-Ply to Radial Tire Conversion for the 1967 Plymouth Valiant
The original 650-13 size has four radial-equivalent paths, while 700-13 has three. For 650-13, those options are 175R13 as an 80-series metric radial, P175/75R13 as a 75-series P-metric radial, P185/70R13 as a 70-series P-metric radial, and 650R13 as a bias-look radial. For 700-13, the equivalents are 185R13, P185/75R13, and P205/70R13. Both primary sizes reference a 4-6 inch recommended rim-width range, and any change should be checked against wheel width, overall dimensions, and vehicle clearance.

Best 1967 Plymouth Valiant Tires for Sale
Available 1967 Plymouth Valiant tire choices focus on 650-13 and 700-13 bias-ply fitments from Coker Classic, US Royal, and Firestone. Buyers can compare classic tire series and whitewall treatments, including narrow and wide whitewall styles, while keeping the correct 13-inch rim fitment in view.
These FAQs focus on the exact tire sizes used on the 1967 Plymouth Valiant, how sub-model fitment changes the decision, what radial equivalents mean, and what to inspect before putting a restored or regularly driven car on the road.
Tire Size & Fitment
What tire size fits a 1967 Plymouth Valiant?
The 1967 Plymouth Valiant uses two primary tire sizes: 650-13 and 700-13, both in bias-ply construction for 13-inch rims. The 6-cylinder Valiant can use either 650-13 or 700-13, while the 8-cylinder cars and all models with air conditioning use 700-13.
That means the first step is confirming the exact configuration of the car rather than choosing by appearance alone. A Valiant that has been changed over the years may also have different wheels than it left with, so checking the current rim diameter and width before selecting a tire helps avoid ordering the wrong size.
What size rim does a 1967 Plymouth Valiant use?
The tire fitments used on the 1967 Plymouth Valiant are built around a 13-inch rim diameter. Both 650-13 and 700-13 use that same rim diameter, so the main fitment difference is tire size rather than wheel diameter.
Rim diameter is only part of the check, though, because the product range also carries specific rim-width recommendations. Measuring the actual wheels on the car is worthwhile, especially on older Mopars that may have replacement steel wheels or aftermarket wheels, since the right 13-inch diameter does not automatically confirm the right width for every tire.
Do all 1967 Plymouth Valiant sub-models use the same tire size?
No, the 1967 Plymouth Valiant does not use one universal tire size across every covered sub-model. The 6-cylinder version can use 650-13 or 700-13, while the 8-cylinder Valiant and all models with air conditioning use 700-13.
That difference matters because a buyer cannot assume that every Valiant should be fitted with the same tire simply because all of them ride on 13-inch rims. Engine and equipment level affect the correct starting point, so matching the tire to the sub-model and checking the wheel already on the car is the safest way to narrow the choice.
Bias-Ply & Radial Options
Is 650-13 a bias-ply or radial tire for the 1967 Plymouth Valiant?
For the 1967 Plymouth Valiant, 650-13 is a primary bias-ply tire size. It is one of the original-style fitments used on 13-inch rims, and the available products in this size follow that traditional bias-ply construction rather than a modern radial format.
That matters because a buyer deciding on 650-13 is really choosing between staying with the original-style bias-ply fitment or moving to one of the recognized radial equivalents. Construction affects both appearance and how the car feels on the road, so wheel width, clearance, and the overall condition of the suspension should be reviewed before changing away from bias-ply.
What radial tire sizes are equivalent to 650-13 and 700-13?
For 650-13, radial equivalents include 175R13, P175/75R13, P185/70R13, and the bias-look radial 650R13. For 700-13, the equivalent radial sizes are 185R13, P185/75R13, and P205/70R13. These alternatives cover an 80-series metric format, a 75-series P-metric option, and a lower-profile 70-series P-metric option.
Each of those sizes should be treated as an alternative, not as an automatic interchange. The recommended rim-width range for both primary sizes is 4-6 inches, and any radial conversion deserves a careful check of wheel width, overall tire dimensions, steering clearance, and fender clearance before the change is made.
Should I use bias-ply or radial tires on a 1967 Plymouth Valiant?
That choice depends on how the 1967 Plymouth Valiant is being used and what matters most to the owner. Bias-ply tires preserve the traditional construction and period-style look tied to the car's original fitment, while radial equivalents give another path for owners who want a modernized tire format in a comparable size range.
A restoration-oriented car often stays closer to the original bias-ply presentation, especially when whitewall style is part of the finished look. A Valiant driven more regularly may lead an owner to consider radial equivalents, but the decision should include wheel compatibility, clearance checks, and a close look at the car's current suspension and steering condition.
Choosing the Right Tire
What should I consider when choosing a 1967 Plymouth Valiant tire?
Start with the correct primary size for the car: 650-13 or 700-13, both on 13-inch rims and both in bias-ply construction. From there, the real comparison involves the exact sub-model, the wheel width on the car, the tire's series, sidewall treatment, and whether the goal is a restoration-style appearance or a radial-equivalent alternative.
It also helps to think about how the Valiant will be used. A car built around original-style presentation may call for one of the classic whitewall bias-ply options, while a driver-focused setup may push the decision toward an equivalent radial after careful fitment checks. Getting the size and wheel relationship right should come before choosing appearance details.
What sidewall styles are available for 1967 Plymouth Valiant tires?
The available sidewall styles for 1967 Plymouth Valiant tire sizes include wide whitewall and narrow whitewall treatments. In 650-13, both Coker Classic and US Royal offer wide and narrow whitewall choices, while the 700-13 Firestone option uses a wide whitewall style.
Sidewall style can change the visual character of the car even when the tire size stays the same. A wider whitewall tends to give a stronger mid-century presentation, while a narrower whitewall looks more restrained, so the right choice usually comes down to the look of the individual Valiant and the era-specific appearance the owner wants to emphasize.
What brands offer tires for the 1967 Plymouth Valiant?
The 1967 Plymouth Valiant tire sizes are available from Coker Classic, US Royal, and Firestone. Coker Classic and US Royal appear in the 650-13 size with multiple whitewall treatments, while Firestone covers the 700-13 size in a classic bias-ply offering.
Brand choice should be weighed alongside the actual size needed for the car, since not every brand appears in both primary fitments. Once the correct size is confirmed, comparing brand by tire series, sidewall style, rim-width specification, and load figure at the stated pressure gives a more useful basis for selection than picking by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Plymouth Valiant?
A period-style 1967 Plymouth Valiant usually starts with the correct bias-ply size for the specific configuration, either 650-13 or 700-13. From there, the most relevant choices are traditional bias-ply tire series and the whitewall treatment that best matches the car's intended finished look.
For many restorations, staying with bias-ply construction preserves the right overall stance and visual character better than a modern radial profile. Exact originality can vary by trim, market, and prior restoration history, so owners pursuing a highly exact presentation should compare their choice against marque references, period photos, and other vehicle-specific historical sources.
How does tire construction affect the appearance of a restored 1967 Plymouth Valiant?
Tire construction changes more than road feel on a restored 1967 Plymouth Valiant; it also changes the car's visual presence. A bias-ply tire keeps the traditional construction associated with the Valiant's original-era fitment, while a radial equivalent can alter the look even when it stays in a comparable size family.
That difference becomes more noticeable when whitewall styling is part of the restoration plan. Owners trying to maintain a distinctly sixties presentation often favor bias-ply construction and a carefully chosen whitewall width, while owners balancing appearance with regular road use may compare radial alternatives more closely after checking how the tire will sit on the wheel and within the fender opening.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Plymouth Valiant?
Yes, modifications can change tire fitment on a 1967 Plymouth Valiant even when the car still appears to have the correct 13-inch wheel diameter. Aftermarket wheels, changes in wheel width, suspension alterations, or body and steering adjustments can all affect how a 650-13, 700-13, or equivalent radial alternative sits on the car.
That is why a modified Valiant should be checked by measurement rather than assumption. Wheel width, inner and outer clearance, and any signs of interference at full steering lock matter before a new set is installed. The more the car has moved away from its original setup, the more important it becomes to verify the actual hardware already on it.
What should I inspect before driving a 1967 Plymouth Valiant on new tires?
Before driving a 1967 Plymouth Valiant on new tires, inspect the wheels for correct diameter and usable condition, confirm the wheel width suits the tire being installed, and make sure the tires are inflated properly. It is also smart to look over steering and suspension parts so the new tires are not being asked to compensate for worn mechanical components.
A short clearance check should follow once the tires are mounted. Turn the steering from lock to lock, look for fender or suspension contact, and recheck after the first few miles for any rub marks or unusual wear. On an older compact car, that basic inspection routine helps protect both the new tires and the drivability of the car.
How should 650-13 or 700-13 tires on a collector 1967 Plymouth Valiant be maintained?
Collector-car tires on a 1967 Plymouth Valiant should be maintained with regular pressure checks, periodic visual inspections, and attention to age-related condition even if the car is driven only occasionally. Look closely for sidewall cracking, bulges, cuts, uneven wear, or any sign that the tire is losing air between drives.
Storage conditions matter just as much as mileage on a low-use Valiant. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and moving the car occasionally can help avoid long-term flat spotting. A tire that looks acceptable at a glance can still deserve replacement if age or condition raises concern.
