1964 Plymouth 8 Cyl. Tires

The 1964 Plymouth 8 Cyl. uses two primary tire sizes: 700-14 and 750-14. Both are bias-ply sizes designed for 14-inch rims, so the correct choice is not about radial versus bias-ply at the basic fitment level, but about confirming which of the two original-style sizes belongs on the car’s present setup.

Because the covered Base configuration can be associated with either size, the safest next step is to inspect the tires already on the car and confirm wheel width before ordering replacements. That helps keep the stance, clearance, and visual proportion consistent with the Plymouth’s current configuration instead of assuming every 1964 V8 Plymouth used one size only.

The primary tire fitments for a 1964 Plymouth 8 Cyl. are built around a 14-inch rim diameter. Both 700-14 and 750-14 use that same rim diameter, so the main difference between the two fitments is tire size rather than wheel diameter.

Rim diameter is only part of the picture, though. Several available products also show rim-width guidance, and that becomes important if the car has replacement wheels or a non-stock setup. A 14-inch wheel still needs to be the right width for the tire chosen, and clearance should be checked if the Plymouth has had wheel, brake, or suspension changes over time.

On a 1964 Plymouth 8 Cyl., 700-14 is a numeric bias-ply size. The 700 portion reflects an approximate nominal section width of 7.00 inches, while the 14 refers to the rim diameter in inches. It is an older sizing system commonly seen on American vehicles of this era.

Understanding that format helps when comparing period-style tires with modern radial alternatives. A 700-14 is not read the same way as a modern metric radial, so matching by appearance alone can be misleading. If the Plymouth is being converted from its original-style bias-ply fitment to a radial equivalent, wheel width and overall fit should be checked before making the change.

For the 1964 Plymouth 8 Cyl., 700-14 is a primary bias-ply tire size. It uses the older numeric bias-ply format rather than a modern radial designation, and available products in this size are traditional bias-ply offerings with blackwall or narrow whitewall sidewall treatments.

That matters because staying with 700-14 bias-ply construction preserves the original-style sizing system and period presentation. Buyers who want a different road-use character can compare radial equivalents, but the original fitment category remains bias-ply. Any construction change should be checked against the wheel, the Plymouth’s current stance, and available space around the fenders and steering components.

Radial equivalents for 700-14 include 185R14, P195/75R14, and P205/70R14. Radial equivalents for 750-14 include 195R14, P205/75R14, P215/70R14, and 750R14, with 750R14 serving as a bias-look radial option for buyers who want a more traditional visual presentation.

Those equivalents span several sizing conventions, from Euro-metric radial to P-metric radial and bias-look radial formats. They provide useful alternatives to the original-style bias-ply sizes, but they should not be treated as automatic substitutions. Wheel width, overall dimensions, steering clearance, and the Plymouth’s actual wheel setup all deserve a careful check before any radial-equivalent conversion.

That choice depends on how the 1964 Plymouth 8 Cyl. is being used and how closely the owner wants to stay with a traditional presentation. The primary fitments are bias-ply, with 700-14 and 750-14 both falling into that category, while several radial equivalents are available for buyers considering a different construction.

Bias-ply tires support a period-style look and keep the car within its original sizing tradition. Radial equivalents can be considered when road use is the priority, but the change should be approached as a full fitment decision rather than a simple size swap. Wheel width, tire dimensions, and body or steering clearance should all be verified before moving away from the original construction type.

Start with the correct primary size, since the 1964 Plymouth 8 Cyl. can use either 700-14 or 750-14. After size is confirmed, compare construction, sidewall style, rim-width compatibility, and the visual character of the tire. Those factors matter more here than chasing a single universal answer.

A narrower 700-14 and a wider 750-14 should not be treated as interchangeable just because both fit 14-inch rims. Buyers should also think about how the car will be used, whether the goal is a traditional blackwall or whitewall look, and whether the wheel setup still matches the tire’s recommended width range.

The available sidewall styles for the 1964 Plymouth 8 Cyl. include blackwall, narrow whitewall, wide whitewall, and redline, depending on tire size and product line. The broader variety appears in 750-14, while 700-14 choices are more limited and focus on blackwall or narrow whitewall presentations.

Sidewall treatment has a major effect on how the car reads visually, especially on a mid-1960s Plymouth with a tall bias-ply profile. A buyer choosing for restoration style may focus on whitewall width or redline appearance, while a more understated street car may suit a blackwall. The right choice depends on the look being pursued, not just the tire size itself.

Tires for the 1964 Plymouth 8 Cyl. are available from BFGoodrich, US Royal, Coker Classic, Firestone, Universal Vintage Tire, and Goodyear. Most of that variety appears in 750-14, where multiple series and sidewall treatments are available across several classic-style bias-ply offerings.

Brand choice should be considered alongside size, sidewall style, and tire series rather than treated as the only decision. Two tires may share the same nominal size but differ in rim-width guidance, load specification, or visual presentation. Comparing those practical details helps narrow the field more effectively than choosing a brand name first.

A period-style 1964 Plymouth 8 Cyl. starts with one of its primary bias-ply sizes, either 700-14 or 750-14, depending on the car’s setup. From there, the best choice depends on the intended appearance, since available options include blackwall, narrow whitewall, wide whitewall, and redline treatments in classic bias-ply series.

For many restorations, the key is choosing a tire that looks right on the car before getting into brand preference. Sidewall treatment can change the whole stance and visual era of the Plymouth. If exact originality matters at a judged level, the final decision should be checked against marque-specific references, historical photos, or other vehicle-specific documentation.

Tire construction affects more than ride feel on a restored 1964 Plymouth 8 Cyl.; it also changes how the car presents visually. The original-style fitments are bias-ply, and that construction supports the tall, traditional profile most buyers associate with a mid-1960s American car of this type.

A radial equivalent can still be a sensible alternative, especially for road use, but it should be viewed as a different presentation rather than the same tire in another material. Buyers who want a more traditional look may stay with bias-ply or consider a bias-look radial where available. The right answer depends on whether appearance or construction type takes priority.

Yes, modifications can affect tire fitment on a 1964 Plymouth 8 Cyl. even when the tire size itself is correct on paper. Aftermarket wheels, altered wheel width, suspension changes, brake conversions, or ride-height changes can all influence whether a 700-14, 750-14, or radial equivalent has proper clearance.

That is especially important on a car that may have been changed over decades of ownership. A 14-inch rim diameter alone does not confirm compatibility. Tire selection should be checked against the wheel’s actual width and the available space at the fenders and steering components, particularly if the car no longer wears its original-style wheels.

Before driving a 1964 Plymouth 8 Cyl. on new tires, inspect wheel condition, confirm the wheel size matches the tire selected, and make sure the tires are inflated appropriately for the product being used. It is also wise to look over suspension and steering components so the new tires are not being asked to compensate for worn hardware.

A short initial drive should be followed by another check for rubbing, unusual wear, or any sign of contact at full steering lock. Collector cars often sit for long periods, so new tires should be paired with a fresh inspection of brake function, alignment behavior, and air retention rather than assuming the rest of the chassis is ready for road use.

Collector-car tires on a 1964 Plymouth 8 Cyl. should be inspected regularly for air loss, sidewall cracking, cuts, bulges, and uneven tread wear, even if the car is driven only occasionally. Low annual mileage does not stop a tire from aging, and long periods of storage can be hard on bias-ply tires as well as radial alternatives.

Storage conditions matter just as much as mileage. Keeping the Plymouth away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition between drives. Tire pressure should be checked before road use, and any car that has been sitting for a season deserves a close look at the tires before heading out on a longer trip.
