1964 Plymouth 6 Cyl. Tires

The 1964 Plymouth 6 Cyl. uses two primary tire sizes: 700-14 and 750-14. Both are bias-ply sizes built for 14-inch rims, and the Base sub-model is associated with both fitments rather than only one dedicated size.

That makes the real decision less about model-year lookup and more about confirming the car’s current wheel and tire setup. Checking the existing tire size, wheel width, and overall clearance helps determine whether the Plymouth should stay with 700-14 or move forward with 750-14 within the correct 14-inch fitment family.

The primary tire fitments for the 1964 Plymouth 6 Cyl. are built around a 14-inch rim diameter. Both 700-14 and 750-14 use that same rim diameter, so the size difference is in tire width and overall fitment character rather than a switch to a different wheel diameter.

Rim diameter is only part of the check, though. Product specifications for these tires also show rim-width considerations, and that matters when choosing between the narrower 700-14 and the wider 750-14. A Plymouth with replacement wheels should have both wheel diameter and wheel width confirmed before a new set is selected.

Both 700-14 and 750-14 are numeric bias-ply tire sizes. In this system, the first number refers to the tire’s nominal section width in inches, so 7.00 is narrower than 7.50, and the final number identifies the 14-inch rim diameter.

Understanding that difference helps when choosing between the two Plymouth fitments. A 700-14 keeps the car within the narrower primary size range, while a 750-14 moves to a wider bias-ply option with a broader assortment of sidewall styles and brands. Wheel width and vehicle clearance should be checked before changing from one to the other.

On the 1964 Plymouth 6 Cyl., both 700-14 and 750-14 are primary bias-ply tire sizes. They are not metric radials or modern P-metric sizes in their original form, and the available primary products in these Plymouth fitments are bias-ply tires.

That matters because a buyer can either stay with the original-style construction or evaluate a radial equivalent separately. Keeping bias-ply construction supports a more traditional presentation, while a radial conversion should be approached as an alternative setup that still requires wheel, width, and clearance checks rather than an automatic interchange.

For 700-14, radial equivalents include 185R14, P195/75R14, and P205/70R14. For 750-14, the radial equivalents are 195R14, P205/75R14, P215/70R14, and 750R14, with the 750R14 serving as a bias-look radial alternative.

Those choices differ by sizing convention and profile family, so they should be compared carefully rather than treated as the same tire in a different label. The recommended rim-width range for these radial equivalents is 4 to 6 inches, and the vehicle should also be checked for wheel compatibility and physical clearance before changing construction.

That choice depends on how the 1964 Plymouth 6 Cyl. will be used and how closely the owner wants to retain its original-style tire construction. The primary fitments are bias-ply, while the listed radial sizes are alternatives for buyers who want to consider a more modern construction in a comparable size range.

A bias-ply tire keeps the car aligned with its period tire format and appearance choices, especially in whitewall or blackwall form. A radial alternative can be considered, but the switch should be evaluated around wheel width, overall fitment, suspension condition, and the actual stance or clearance available on the Plymouth rather than appearance alone.

Start with the correct primary size for the car’s actual setup, since the 1964 Plymouth 6 Cyl. is associated with both 700-14 and 750-14. From there, compare construction, wheel-width compatibility, sidewall appearance, brand, and the tire series available in the size that best matches the car.

The 700-14 range is simpler, while 750-14 opens a much broader mix of blackwall, narrow whitewall, wide whitewall, and redline choices. That makes 750-14 especially useful for owners who want more visual flexibility, but the car’s wheels still need to be appropriate for the selected tire before appearance becomes the deciding factor.

Sidewall choices for the 1964 Plymouth 6 Cyl. include blackwall, narrow whitewall, wide whitewall, and redline, depending on the tire size selected. The broadest variety appears in 750-14, while 700-14 is available in blackwall and narrow whitewall form.

That variety lets the tire do a lot of visual work on a mid-1960s Plymouth. A blackwall gives the car a plainer, understated look, while whitewall and redline styles shift the presentation toward a more restoration-oriented or custom-leaning appearance. The first step is still choosing the correct tire size, then selecting the sidewall treatment that matches the car’s intended look.

Available tires for the 1964 Plymouth 6 Cyl. come from BFGoodrich, US Royal, Firestone, Universal Vintage Tire, Coker Classic, and Goodyear. Brand availability depends partly on size, with 700-14 offered in a narrower selection and 750-14 carrying the widest spread of brand and sidewall combinations.

Choosing among brands is usually less about chasing a single answer and more about comparing the presentation each tire offers within the correct size. Tire series, sidewall style, rim-width specification, and load figures can all help narrow the field once the Plymouth’s actual fitment has been confirmed.

A period-style approach for a 1964 Plymouth 6 Cyl. starts with its primary bias-ply sizes, 700-14 or 750-14, rather than jumping directly to a modern radial. From there, the best match depends on the car’s wheel setup and the visual direction of the restoration, since both blackwall and whitewall treatments are available.

The 750-14 size offers the broadest period-style presentation, including narrow whitewall, wide whitewall, and redline choices across several classic series. When exact originality matters, the tire should be checked against the car’s historical references and existing wheel configuration so appearance goals do not override correct fitment.

Tire construction changes more than ride feel on a restored 1964 Plymouth 6 Cyl.; it also changes the car’s visual character. A bias-ply tire keeps the Plymouth in its original-era sizing language and sidewall proportions, while a radial alternative introduces a more modern construction even when chosen in an equivalent size range.

That is why many restoration-minded owners decide on construction before choosing a brand or sidewall treatment. A bias-ply setup supports a traditional mid-1960s presentation, and a bias-look radial can soften the visual change in the 750-14 fitment. Either way, the wheel and body clearance should be verified before finalizing the switch.

Yes, modifications can change tire fitment on a 1964 Plymouth 6 Cyl. even when the tire size itself falls within the vehicle’s primary fitment range. Aftermarket wheels, wheel-width changes, altered offsets, suspension work, or body modifications can all influence whether 700-14, 750-14, or a radial equivalent is still appropriate.

A Plymouth that no longer has its original-style wheel and suspension setup should be measured instead of assumed. Confirm the actual rim diameter and width, then check steering travel and fender clearance with the car at normal ride height. That step becomes especially important when considering the wider 750-14 size or any radial alternative.

Before road use, inspect the wheels for correct diameter and condition, make sure the tires are inflated properly for the setup being used, and confirm there is no interference at the fenders or during steering movement. It also helps to look over suspension and steering components so the new tires are not being asked to compensate for unrelated mechanical wear.

Collector cars often sit longer than modern daily drivers, so a careful first drive matters. Recheck air pressure after installation, listen for rubbing, and watch for pull, vibration, or uneven contact. Those signs can point to wheel issues, alignment needs, or clearance problems that should be addressed before putting more miles on the Plymouth.

Collector-car tires on a 1964 Plymouth 6 Cyl. should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is low, a low-use bias-ply tire can still age, so cracking, flat spotting, bulges, cuts, and persistent air loss deserve attention before routine road use.

Storage conditions matter almost as much as mileage on a vintage Plymouth. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve tire condition over time. A short inspection before each drive and a more complete check at regular intervals can prevent an old problem from becoming a roadside one.
