1963 Plymouth Plymouth Tires

The 1963 Plymouth Plymouth uses two primary tire sizes: 700-14 and 750-14. Both are bias-ply sizes designed for 14-inch rims, and the covered sub-model grouping uses those same two size options rather than a separate construction type or different rim diameter.

That means the real fitment question is deciding which of those two sizes belongs on the car’s current setup. Checking the wheel width, the existing tire size, and the car’s overall stance is the best next step before choosing a replacement, especially if the vehicle has had wheel changes or if the goal is to preserve a period-style appearance.

The primary tire fitments for a 1963 Plymouth Plymouth are built around a 14-inch rim diameter. Both 700-14 and 750-14 use that same rim diameter, so the buyer does not need to sort between different wheel diameters when comparing the primary sizes on this page.

Rim diameter is only one part of the fitment picture, though. It is still important to confirm the actual wheel width on the car, because product specifications within these sizes can vary slightly by tire line. That check becomes even more important if the Plymouth has aftermarket wheels or if a radial-equivalent size is being considered.

A 700-14 tire uses a vintage numeric bias-ply sizing format. The 700 portion refers to an approximate 7.00-inch nominal section width, and the 14 identifies the rim diameter in inches. On the 1963 Plymouth Plymouth, that code points to a traditional bias-ply fitment rather than a modern metric radial size.

Understanding that format helps when comparing period-style tires to radial alternatives. A 700-14 should be matched to the correct 14-inch wheel and checked against the car’s actual setup before replacement, since vintage numeric sizing does not translate one-for-one into modern metric naming without reviewing the available equivalent options.

For the 1963 Plymouth Plymouth, 700-14 is a primary bias-ply tire size. It is part of the vehicle’s vintage numeric sizing system and is offered in classic bias-ply construction rather than as a primary radial fitment on this application.

That matters because a buyer choosing 700-14 is usually deciding whether to keep the original-style construction or move to a radial equivalent. If a conversion is being considered, the wheel diameter stays the same at 14 inches, but wheel width, overall dimensions, and clearance should still be checked before changing from bias-ply to radial construction.

Radial equivalents for 750-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, P215/70R14 as a 70-series P-metric radial, and 750R14 as a bias-look radial. Those options give the 1963 Plymouth Plymouth several ways to move from a vintage bias-ply size into radial construction.

Each of those equivalents uses a different sizing convention and may suit a different goal, whether the priority is a more traditional radial profile or a bias-look presentation. The recommended rim-width range is 4-6 inches, but wheel compatibility, tire dimensions, and vehicle clearance still need to be confirmed before making the change.

Start by confirming the original tire size on the car, then compare it to the correct radial-equivalent options for that size. For this Plymouth, 700-14 and 750-14 each have specific radial equivalents, and those alternatives should be treated as fitment options to evaluate rather than automatic substitutions.

The most important checks are wheel diameter, wheel width, tire clearance at the fenders and steering components, and the car’s overall suspension condition. A vehicle that has been lowered, fitted with different wheels, or sitting on worn suspension parts may respond differently to a radial conversion than a stock-height Plymouth with original wheel dimensions.

Choosing a 750-14 tire starts with confirming that 750-14 is the right primary size for the car. From there, the meaningful differences are brand, tire series, sidewall style, and product specifications such as rim-width compatibility, weight, and load capacity where those figures are given.

That makes 750-14 less about simple fitment and more about matching the tire to the car’s purpose. A restoration-oriented Plymouth may call for a particular whitewall or redline presentation, while a more understated driver may lean toward blackwall. The wheel setup should still be verified before settling on one tire line over another.

Available sidewall styles for the 1963 Plymouth Plymouth include blackwall, narrow whitewall, wide whitewall, and redline, depending on the tire size and product line. The broadest sidewall variety appears in 750-14, while 700-14 is available in blackwall and narrow whitewall configurations.

That variety lets the buyer tune the car’s appearance without changing the primary vintage sizing format. Sidewall treatment can significantly alter the look of a full-size early-1960s Plymouth, so it helps to decide whether the goal is a restrained driver-style presentation, a more upscale whitewall look, or a sportier period-style redline treatment.

Tires for the 1963 Plymouth Plymouth are available from BFGoodrich, US Royal, Coker Classic, Firestone, Universal Vintage Tire, and Goodyear, depending on size. The 700-14 offerings are narrower in brand selection, while 750-14 opens up the widest range of classic bias-ply choices.

That brand spread is useful because it gives the buyer more than one path to the right look and specification. Some lines focus on blackwall and whitewall variations, while others add redline or different classic series names. The best comparison is not brand alone, but brand plus correct size, sidewall style, and wheel compatibility.

A period-style 1963 Plymouth Plymouth starts with the correct primary bias-ply size, either 700-14 or 750-14 depending on the car’s setup. From there, the visual character can be shaped through blackwall, narrow whitewall, wide whitewall, or redline sidewall treatments offered in the available classic tire lines.

The right choice depends on how authentic or era-inspired the finished car needs to appear. If exact originality matters, it is wise to compare the tire choice against period photos, marque references, or restoration documentation for the specific car. For many owners, the goal is a convincing period-style look rather than an exact historical duplicate.

Tire construction changes more than ride feel on a restored 1963 Plymouth Plymouth; it also affects visual character. A bias-ply tire preserves the vintage sizing format and traditional profile associated with the car’s era, while a radial equivalent can change the presentation even when it remains close in overall fitment intent.

That is why many restoration-minded buyers decide on construction before narrowing down brand or sidewall style. Bias-ply tires usually make the strongest visual match for an early-1960s presentation, while radial equivalents appeal to owners who want a different road-use experience. Either way, the wheel dimensions and body clearance should be confirmed before final selection.

Yes, modifications can affect tire fitment on a 1963 Plymouth Plymouth even when the tire size itself is correct. Changes to wheel width, wheel offset, ride height, springs, or suspension components can alter how a 700-14 or 750-14 tire sits in the wheel opening and how much clearance it has during turning and suspension movement.

That is especially important on a collector car that may have seen wheel swaps over the years. A Plymouth with aftermarket wheels or altered suspension should be checked carefully before replacement tires are chosen, because the original size alone does not account for every change that can influence clearance and overall compatibility.

Before driving a 1963 Plymouth Plymouth on new tires, inspect the wheels for correct diameter and condition, confirm the lug hardware is appropriate, and make sure the tires are inflated properly for service. It is also smart to check that the suspension, steering components, and alignment are in sound condition so the new tires are not compromised right away.

A short test drive should include listening for rubbing, checking steering feel, and confirming that nothing contacts the tire through turns or over bumps. Collector cars often sit for long periods, so it also helps to look over brake condition, wheel bearings, and any signs of fluid leakage before putting the car back into regular road use.

Collector-car tires in 700-14 or 750-14 should be maintained with regular pressure checks, visual inspections, and periodic review of tread and sidewall condition. Even if the 1963 Plymouth Plymouth is driven infrequently, bias-ply tires still need attention for cracking, bulges, cuts, and signs of air loss that can develop with age and storage.

Storage conditions matter almost as much as mileage on a low-use car. Keeping the Plymouth away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the tires, and moving the car occasionally can reduce long-term flat spotting. Before any longer drive, check pressure again and inspect each tire closely, including the inner sidewall if accessible.
