In 1964, Plymouth covered a wide slice of the American market, from practical compact transportation to full-size family cars and wagons with distinctly mid-century styling. That broad range means 1964 Plymouth tire fitment is not a one-size-fits-all subject, even though every size used this year stays true to the era with bias-ply construction. Across four model groups, five different sizes appear, with the Valiant on 13-inch fitments and the larger six-cylinder, eight-cylinder, and wagon models using 14-inch sizes. Before choosing a tire for a 1964 Plymouth, the first step is confirming your exact model, then matching the correct size and sidewall look to your restoration goals.
Which Tire Size Is Right for Your 1964 Plymouth
Five tire sizes fit 1964 Plymouth vehicles, and they vary by model rather than carrying across the full lineup. The key decision is confirming whether your car uses a 13-inch or 14-inch rim first, then narrowing down the correct bias-ply size for the specific model. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 1964|Fit(s): 6 Cyl., 8 Cyl.|Construction: Bias Ply|Rim: 14 in
700-14 is a numeric bias-ply size in which 7.00 denotes nominal section width and 14 denotes the wheel diameter, and on 1964 Plymouth it is specific to six-cylinder and eight-cylinder cars rather than the full model range. This size is available from BFGoodrich with blackwall and narrow whitewall sidewall styles, and its products carry a 1360-pound load rating at 32 psi. It suits a 1964 Plymouth owner who wants the original-style bias-ply look and road manners appropriate to a mid-1960s full-size car.
750-14 is a numeric bias-ply size with a nominal 7.50-inch section width and a 14-inch rim diameter, and it appears on larger 1964 Plymouth passenger cars as well as the wagon. BFGoodrich, US Royal, and Coker Classic offer this size with narrow whitewall, wide whitewall, and redline sidewall styles, and load ratings in this group reach 1500 to 1580 pounds at 32 psi. It is the broadest 14-inch fitment in the 1964 Plymouth range and is the natural choice when your car calls for a fuller-size bias-ply stance with period-correct sidewall options.
Year(s): 1964|Fit(s): Valiant|Construction: Bias Ply|Rim: 13 in
650-13 is a numeric bias-ply size in which 6.50 denotes nominal section width and 13 identifies the wheel diameter, and on 1964 Plymouth it is exclusive to the Valiant. Coker Classic and US Royal both offer it with wide whitewall and narrow whitewall styling, and these products carry a 1150-pound load rating at 32 psi. It is the better fit for a Valiant owner aiming to preserve the compact car's original-scale appearance and period-correct bias-ply feel.
Year(s): 1964|Fit(s): Valiant|Construction: Bias Ply|Rim: 13 in
700-13 is a numeric bias-ply size with a nominal 7.00-inch section width and a 13-inch rim diameter, and it is another Valiant-specific fitment rather than a universal 1964 Plymouth size. Firestone offers this size with a wide whitewall sidewall style, and its product carries a 1270-pound load rating at 32 psi. It is a sensible choice for a Valiant owner seeking a slightly larger 13-inch period-style fitment while staying within the bias-ply character appropriate to the car.
Year(s): 1964|Fit(s): Wagon|Construction: Bias Ply|Rim: 14 in
800-14 is a numeric bias-ply size in which 8.00 denotes nominal section width and 14 denotes the wheel diameter, and for 1964 Plymouth it is specific to the wagon. BFGoodrich and Universal Vintage Tire offer this size in blackwall, narrow whitewall, and wide whitewall versions, and BFGoodrich examples carry a 1620-pound load rating at 32 psi. It is the heaviest-looking fitment in the range and best matches the wagon when you want the stance and visual presence associated with a larger 14-inch bias-ply tire.
Four Plymouth model groups are covered for 1964, and tire size changes with the model rather than staying uniform across the lineup. In practical terms, that means year and make alone are not enough; you need to identify whether you have a six-cylinder or eight-cylinder full-size car, a compact Valiant, or a wagon before choosing a tire. Select a model below to narrow the fitment history and see the products that match it.
1964 Plymouth 6 Cyl.
A 1964 Plymouth six-cylinder car typically represented the value-minded side of the full-size Plymouth range, pairing straightforward mechanicals with the broad, clean body lines of the period. Its tires mount on 14-inch rims, with two bias-ply sizes associated with this model group depending on the exact application and desired original look.
A 1964 Plymouth eight-cylinder car sat in the same full-size family as the six, but with the added character expected from V8-powered mid-1960s American transportation. Its tire fitments also use 14-inch rims, with two bias-ply sizes that preserve the era-correct appearance and driving character of a larger Plymouth sedan or coupe.
The 1964 Plymouth Valiant was Plymouth's compact offering, known for tidy dimensions, practical packaging, and a distinct identity apart from the larger Plymouth cars. Its tires mount on 13-inch rims, and both associated sizes stay within a bias-ply presentation that suits a stock or restoration-focused Valiant.
A 1964 Plymouth wagon was built for family hauling and cargo duty, and wagons of this era often carried their own visual and load-bearing tire requirements compared with sedans. This model group uses 14-inch rims and appears with two larger bias-ply sizes that complement the wagon's heavier-duty, full-size character.
Twenty-five products are available across five tire sizes for 1964 Plymouth vehicles. 700-14 has 2 BFGoodrich bias-ply choices in blackwall and narrow whitewall; 750-14 has 11 bias-ply choices from BFGoodrich, US Royal, and Coker Classic in narrow whitewall, wide whitewall, and redline; 650-13 has 4 bias-ply choices from Coker Classic and US Royal in narrow and wide whitewall; 700-13 has 1 Firestone bias-ply wide whitewall; 800-14 has 7 bias-ply choices from BFGoodrich and Universal Vintage Tire in blackwall, narrow whitewall, and wide whitewall.
These answers focus on the model-by-model tire differences across the 1964 Plymouth range, from compact Valiant 13-inch fitments to larger 14-inch sizes for full-size cars and wagons. They also cover sidewall styling, rim width, storage, road use, and restoration-minded choices for a mid-1960s Mopar.
Size Basics & Fitment
What tire sizes fit 1964 Plymouth vehicles?
1964 Plymouth vehicles use five bias-ply tire sizes across four model groups: 700-14 and 750-14 for Plymouth 6 Cyl., 700-14 and 750-14 for Plymouth 8 Cyl., 650-13 and 700-13 for Plymouth Valiant, and 750-14 and 800-14 for Plymouth Wagon. The 13-inch sizes mount on Valiant rims, while the larger Plymouth cars and wagon use 14-inch rims. Rim width ranges covered by the available products are 4.50 to 5.00 inches for 650-13, 4.00 to 5.00 inches for 700-13, 5.00 to 5.50 inches for 700-14 and 750-14, and 5.00 to 6.00 inches for 800-14.
That split matters because a 1964 Plymouth owner cannot choose by year alone. A Valiant owner needs to stay within the 13-inch family, while full-size six-cylinder and eight-cylinder cars stay with 14-inch fitments, and the wagon reaches the largest 14-inch option in the group. Start by identifying the model, then confirm the wheel diameter and rim width on the actual car before settling on a final size.
What does 700-14 mean on a 1964 Plymouth tire?
On a 1964 Plymouth, 700-14 is a numeric bias-ply size. The 7.00 portion refers to the tire's nominal section width in inches, while the 14 identifies the wheel diameter in inches. Within the 1964 Plymouth range, this size belongs to the six-cylinder and eight-cylinder full-size cars rather than the Valiant or the wagon-specific larger fitment. Available examples use 14-inch rims and fit rim widths from 5.00 to 5.50 inches.
For a buyer, the important takeaway is that 700-14 is an original-style full-size Plymouth size from the bias-ply era, not a modern metric radial size. If your car is a full-size 1964 Plymouth and the wheel measures 14 inches, 700-14 may be correct, but it should still be checked against the wheel and the vehicle's current setup. That is especially helpful on older cars that may have been changed over the years.
Do all 1964 Plymouth models use the same tire size?
No. The 1964 Plymouth lineup uses different tire sizes depending on the model. Full-size six-cylinder and eight-cylinder cars share 700-14 and 750-14, the Valiant uses 650-13 and 700-13, and the wagon uses 750-14 and 800-14. Every size in the range is bias-ply, but the wheel diameter and overall fitment family change between compact and full-size applications.
That means identifying the model is the first real fitment step. A buyer comparing all 1964 Plymouth tires may see several sizes that look close in name, yet a 13-inch Valiant fitment and a 14-inch wagon fitment are not interchangeable. If the car is new to you or has aftermarket wheels, verify the wheel diameter on the vehicle before choosing a tire so you can narrow the search quickly and accurately.
Buying the Right Tire
What sidewall styles are available for 1964 Plymouth tires?
1964 Plymouth tires are available in several period-style sidewall treatments depending on size. 700-14 comes in blackwall and narrow whitewall, 750-14 comes in narrow whitewall, wide whitewall, and redline, 650-13 comes in narrow whitewall and wide whitewall, 700-13 comes in wide whitewall, and 800-14 comes in blackwall, narrow whitewall, and wide whitewall. That gives the full-size cars and wagon the broadest visual range, while Valiant fitments stay centered on whitewall presentations.
The right choice comes down to how you want the car to read visually. A blackwall often suits a plainer, more restrained appearance, while whitewalls are strongly associated with mainstream American styling in the early to mid-1960s. Redline is a more specialized look and appears here only in 750-14. If originality matters, compare your car's trim level, market presentation, and restoration goal before choosing a sidewall style.
What brands make tires for 1964 Plymouth vehicles?
Several well-known vintage tire brands cover the 1964 Plymouth range. BFGoodrich appears in 700-14, 750-14, and 800-14; US Royal appears in 750-14 and 650-13; Coker Classic appears in 750-14 and 650-13; Firestone covers 700-13; and Universal Vintage Tire appears in 800-14. Brand choice varies with the tire size, so the exact model and wheel diameter narrow the field before style preferences come into play.
That brand spread gives a 1964 Plymouth owner room to choose around sidewall appearance and the character of each series without leaving the period-correct bias-ply category. Full-size 14-inch applications generally offer the widest brand selection, while some 13-inch Valiant fitments are more specialized. A good approach is to identify the correct size first, then compare the available brands within that size by sidewall style and any load information important to your car.
What is the difference between BFGoodrich and US Royal 750-14 tires for the 1964 Plymouth?
For the 1964 Plymouth in 750-14, BFGoodrich and US Royal share the same 14-inch rim diameter and 5.00 to 5.50 inch rim width range, but they differ in sidewall offerings and load figures. BFGoodrich appears in a narrow whitewall version rated at 1580 pounds at 32 psi, while US Royal appears in narrow whitewall and redline versions rated at 1500 pounds at 32 psi. Both stay within an authentic bias-ply presentation for a mid-1960s Plymouth.
The practical difference is less about basic fit and more about the look you want and the exact product character you prefer. If a redline sidewall matters, US Royal is the option in this size. If your focus is a BFGoodrich-branded period bias-ply with its own sidewall presentation and load figure, that narrows the choice the other way. Compare sidewall styling first, then confirm the tire matches the wheel and intended use of the car.
Fitting & Setup
What rim width do 1964 Plymouth tires require?
Rim width requirements for 1964 Plymouth tires vary by size. The 650-13 fits 4.50 to 5.00 inch rims, the 700-13 fits 4.00 to 5.00 inch rims, the 700-14 and 750-14 fit 5.00 to 5.50 inch rims, and the 800-14 fits 5.00 to 6.00 inch rims. Those ranges matter because the same year and make spans compact, full-size, and wagon applications rather than using one universal wheel package.
Before choosing a tire, measure or confirm the actual wheel on the car instead of assuming it is still original. Older Plymouths are often restored, swapped, or updated, and a wheel that is the correct diameter may still fall outside the ideal width range for the tire you want. Matching tire size to both diameter and rim width helps preserve the intended profile, appearance, and ride characteristics.
Can the original 1964 Plymouth wheels be used with both or all tire sizes?
A single set of original 1964 Plymouth wheels cannot be assumed to work with all tire sizes across the full lineup because the year is split between 13-inch and 14-inch fitments. The Valiant uses 13-inch sizes, while the six-cylinder, eight-cylinder, and wagon models use 14-inch sizes. Within the 14-inch family, 700-14 and 750-14 share the same 5.00 to 5.50 inch rim width range, while 800-14 expands to 5.00 to 6.00 inches.
That means some overlap exists within the full-size and wagon group, but compatibility still needs to be checked against the wheel actually on the car. A wagon owner comparing 750-14 and 800-14 should verify both diameter and rim width before making a change, while a Valiant owner should stay in the 13-inch family entirely. Treat original wheels as a starting point, then confirm the dimensions before mounting a different size.
Maintenance, Storage & Longevity
How should I store a 1964 Plymouth when the tires are fitted?
A 1964 Plymouth should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone-producing equipment. Because every size in this application is bias-ply, long stationary storage can encourage temporary flat-spotting and can be harder on the casing than regular gentle use. A clean floor or tire barrier under the tires is also helpful in damp environments.
For a collector car, the best routine is periodic movement so the tire does not sit on one contact patch for months at a time. If the car will be parked for a very long period, some owners prefer stands used correctly to reduce constant load, but the suspension should still be supported appropriately. Good storage habits protect the sidewalls, preserve ride quality, and reduce surprises when the car comes back out for driving season.
How long do tires on a 1964 Plymouth typically last?
Tires on a 1964 Plymouth are usually judged by age and condition more than mileage, especially on collector cars that spend much of their lives parked. A sound rule is to inspect them carefully beginning around five to seven years of age and to treat roughly ten years as a serious replacement point even if tread remains. The DOT date code, physical condition, and storage history matter more than the number of miles driven.
That age-based approach is important because a lightly used vintage Plymouth can still be riding on old rubber that looks acceptable at first glance. Bias-ply tires may retain their period appearance while quietly developing age-related stiffness or cracking. If the car's tire age is uncertain, checking the date codes and giving the tires a close inspection is one of the smartest maintenance steps before regular driving resumes.
How often should tires on a 1964 Plymouth be inspected?
Tires on a 1964 Plymouth should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread damage, irregular wear, cuts, bulges, and any sign that a tire has lost pressure while parked. Since these are bias-ply applications, changes in shape after storage and signs of age on the sidewall deserve especially close attention.
A quick check takes only a few minutes and can prevent a roadside problem that starts with a car sitting longer than it drives. Include the spare in that routine, because an old spare often becomes the weak link on a vintage car. If the tire appears aged or the car has been stored for a long period, inspect more carefully and correct pressure before heading out on modern roads.
Restoration & Authenticity
What tires were originally fitted to the 1964 Plymouth 6 Cyl.?
A 1964 Plymouth 6 Cyl. would have been fitted with bias-ply tires when new, because bias-ply construction was still standard American practice in this period. Within the 1964 Plymouth range, the six-cylinder full-size cars use 700-14 and 750-14. Those sizes stay true to the era, and sidewall choices such as blackwall or whitewall can significantly affect how original the finished car looks.
If you are restoring a specific body style, trim level, or market-delivery car, the final call should be checked against factory literature, surviving original examples, or a marque club. Tire size, sidewall width, and overall presentation can all matter in a judged setting. The safest path for a restoration-focused owner is to confirm the exact model first, then choose the bias-ply size and sidewall style that best match the car's intended presentation.
Does correct tire fitment matter for showing a 1964 Plymouth?
Yes, correct tire fitment matters on a 1964 Plymouth because judges and knowledgeable enthusiasts often notice whether the size, construction, and sidewall style suit the model and the era. A Valiant on the wrong 14-inch tire family, or a full-size Plymouth shown with a sidewall treatment that clashes with its period presentation, can look out of place even before anyone studies finer details. Bias-ply construction is also part of the visual and historical character of a mid-1960s Plymouth.
For show use, tire choice is not only about whether the tire fits the wheel. It also shapes stance, side profile, and overall authenticity. Event standards vary, so local or marque-specific judging guides are worth checking before making a final decision. If your goal is concours accuracy, start with the model-correct size family and then narrow the whitewall, blackwall, or redline style to suit the way the car would have appeared in period.
What is the difference between Coker Classic and US Royal 650-13 tires for the 1964 Plymouth?
For the 1964 Plymouth in 650-13, Coker Classic and US Royal share the same basic fitment profile: both are bias-ply tires for 13-inch rims, both fit 4.50 to 5.00 inch rim widths, and both carry a 1150-pound load rating at 32 psi. The main difference lies in branding and sidewall presentation. Each brand appears in both narrow whitewall and wide whitewall versions in this size.
That means the choice is largely about the exact look you want on a Valiant and the brand character you prefer in a period-style tire. If your restoration is chasing a certain visual balance between body trim and sidewall width, compare the narrow and wide whitewall treatments first. Once that appearance is settled, staying within the correct 650-13 fitment keeps the compact Plymouth in the right visual and historical lane.
Safety & Road Use
Are 1964 Plymouth tires safe for highway driving?
1964 Plymouth tire choices here are all bias-ply products, and none of the available sizes in this group carry a speed rating letter in the tire size description. That means highway use should be approached with the expectations appropriate to a vintage bias-ply tire and a mid-1960s vehicle. On cars of this age, overall roadworthiness depends as much on brakes, steering, suspension, alignment, and wheel condition as it does on the tires themselves.
A well-maintained 1964 Plymouth can certainly be driven on modern roads, but it should be driven with respect for the behavior of period-style tires and the capabilities of the car as a whole. Before sustained highway use, inspect the tires closely, confirm pressures, and make sure the chassis is in equally sound condition. Safe road use comes from the complete vehicle package, not from tire size alone.
What inflation pressure should I use for 1964 Plymouth tires?
Load and pressure figures vary by size on 1964 Plymouth tires, so one number should not be carried across the entire range. 700-14 products are rated at 1360 pounds at 32 psi, 750-14 products run 1500 to 1580 pounds at 32 psi, 650-13 products are 1150 pounds at 32 psi, 700-13 is 1270 pounds at 32 psi, and BFGoodrich 800-14 examples are 1620 pounds at 32 psi. Those figures describe the tire's rated load relationship, not necessarily the exact pressure your Plymouth should be driven at.
For actual running pressure, use the original owner's manual or factory inflation guidance for the specific model as your baseline, then compare that against the tire manufacturer's information for the reproduction tire you choose. A Valiant, a full-size sedan, and a wagon should not be treated as identical just because they share the same year and make. Keeping pressure tied to the exact size and model helps preserve ride, wear, and handling.
What should I check before taking a 1964 Plymouth on a longer drive?
Before a longer drive in a 1964 Plymouth, inspect each tire for sidewall cracking, cuts, bulges, irregular wear, and any loss of pressure from storage. Check the spare as carefully as the four road tires, because a decades-old spare can be unusable when you actually need it. Since these are bias-ply applications, pay attention to how the car feels during the first miles after sitting, especially if the tires have developed temporary flat spots.
Tires are only one part of the pre-drive routine on a car of this age. It is equally wise to confirm wheel hardware, brakes, steering response, fluid levels, and basic lighting before setting out. If the Plymouth is newly acquired or has not been driven recently, make the first outing a shorter shakedown trip rather than a long highway run. That approach gives you time to catch tire or chassis issues before they become bigger problems.
