1957 Plymouth Plaza & Savoy Tires

The 1957 Plymouth Plaza & Savoy uses two primary tire sizes: 750-14 and 800-14. Both are vintage numeric bias-ply sizes for 14-inch rims, and both appear on the covered Plaza & Savoy fitments for 6-cylinder and 8-cylinder cars.

That means the real task is not choosing between unrelated modern sizes, but confirming which of those two period sizes belongs on the specific car in front of you. A car that has been restored, had wheels changed, or been altered for stance may no longer match its earlier setup, so wheel width, current tire markings, and clearance around the fenders and suspension should all be checked before settling on 750-14 or 800-14.

The 1957 Plymouth Plaza & Savoy uses a 14-inch rim with its primary tire fitments. Both 750-14 and 800-14 are built around that 14-inch rim diameter, so rim diameter stays consistent even though the car has two different tire size options.

Rim diameter is only part of the fitment picture on a collector car. The wheel still needs to suit the tire’s width requirements, and that becomes especially important if the car has replacement wheels or if a radial equivalent is being considered. A quick check of the wheel itself, along with the tire size already on the car, helps prevent ordering a correct-diameter tire that does not suit the actual rim width or overall setup.

The covered 1957 Plymouth Plaza & Savoy 6-cylinder and 8-cylinder sub-models share the same two primary tire sizes: 750-14 and 800-14. Both sub-models use bias-ply construction on 14-inch rims, so there is no separate size split between those two engine-based variations.

That shared fitment keeps the search simpler, but it does not remove the need to verify the car’s current configuration. Many surviving 1957 Plymouths have been restored or modified over the years, and wheel changes can influence which of the two sizes makes sense today. Matching the tire to the car’s actual wheel width, ride height, and intended appearance is more important than relying on the engine designation alone.

On the 1957 Plymouth Plaza & Savoy, 750-14 is a primary bias-ply tire size. It uses the vintage numeric sizing system common to the period, with a nominal 7.50-inch section width and a 14-inch rim diameter rather than a modern metric radial designation.

Keeping 750-14 in bias-ply form usually appeals to owners who want a traditional look and driving character. A radial equivalent can still be considered, but the decision should start with how the car is used and how closely the tire should reflect period presentation. Wheel width, overall stance, and available clearance should all be checked before changing construction, even when staying within the same general size family.

For 750-14, radial equivalents include 195R14, P205/75R14, P215/70R14, and 750R14 as a bias-look radial. For 800-14, radial equivalents include 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial. These options cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a radial built to retain a more traditional visual character.

Those sizes give owners several ways to approach a radial conversion without abandoning the original-era tire language entirely. The choice still needs to be checked against wheel dimensions and the car’s available clearance, since an equivalent is a comparison point rather than an automatic substitute. The recommended rim-width ranges are 4-6 inches for 750-14 and 5-7 inches for 800-14, which makes wheel confirmation especially important.

A radial conversion on a 1957 Plymouth Plaza & Savoy starts with confirming the original tire size on the car, then matching it to the appropriate equivalent size such as 195R14, P205/75R14, P215/70R14, or 750R14 for 750-14, and 205R14, P215/75R14, P225/70R14, or 800R14 for 800-14. Rim diameter and usable wheel width need to align with the radial being considered.

Clearance is the next major checkpoint, especially on an older car that may have replacement wheels, suspension wear, or body changes accumulated over time. Steering travel, fender space, and the car’s current ride height all deserve attention before switching construction. It also helps to decide whether the goal is a modern radial profile or a bias-look radial that keeps a more traditional sidewall presentation.

Start with the correct primary size for the car: 750-14 or 800-14 on a 14-inch rim. From there, the main considerations are whether to stay with traditional bias-ply construction, which sidewall style best suits the car, and how the available tire series compare in rim-width requirements, load figures, and overall presentation.

That matters because two tires in the same nominal size can still serve different restoration or driving goals. A wide whitewall may support a stronger late-1950s visual statement, while a blackwall creates a plainer look, and a redline introduces a more specific styling cue. The right choice usually comes from balancing appearance, wheel compatibility, and how closely the car should reflect a period-style setup.

The 1957 Plymouth Plaza & Savoy tire options include blackwall, narrow whitewall, wide whitewall, and redline sidewall treatments, depending on the size and product line. The broadest range appears in 750-14, while 800-14 includes blackwall, narrow whitewall, and wide whitewall choices.

Sidewall style changes the car’s appearance more than many buyers expect, especially on a 1957 Plymouth where the tire contributes strongly to stance and period presence. A blackwall keeps things restrained, narrow whitewalls offer a modest contrast, and wide whitewalls create a more dramatic mid-century look. Redline is available in 750-14 and can be considered when a more distinctive period-style presentation is the goal.

Tires for the 1957 Plymouth Plaza & Savoy are available from BFGoodrich, US Royal, Firestone, Goodyear, Coker Classic, and Universal Vintage Tire. These brands appear across the 750-14 and 800-14 bias-ply fitments, with some variation by size, sidewall style, and tire series.

Brand choice should be treated as one part of a broader fitment decision rather than the whole decision. The more useful comparison is whether a given tire is offered in the right size, sidewall treatment, and series for the car’s intended look and use. Rim-width specifications and load figures can also differ, so those details deserve as much attention as the brand name on the sidewall.

A period-style 1957 Plymouth Plaza & Savoy usually starts with one of its primary bias-ply sizes, 750-14 or 800-14, rather than jumping immediately to a modern radial format. That keeps the car within the visual language of the late 1950s and opens the door to traditional sidewall treatments such as blackwall, narrow whitewall, wide whitewall, or redline.

The better choice between the two sizes depends on the car’s actual wheel setup and the stance you are trying to preserve. Appearance details matter, but exact originality can vary by trim, market, and prior restoration decisions, so buyers chasing a highly exact presentation should compare the tire choice against marque references and surviving vehicle documentation. For most owners, staying with the correct-size bias-ply format is the strongest starting point.

Tire construction has a visible effect on a restored 1957 Plymouth Plaza & Savoy because bias-ply and radial tires do not present the same way on the car. A bias-ply tire keeps the traditional vintage sizing format and supports the type of sidewall profile many owners associate with a late-1950s restoration.

A radial equivalent can still be a useful option, especially in a bias-look radial form, but the visual impression may differ from a conventional bias-ply tire even when the size relationship is carefully chosen. That is why restoration-minded buyers often decide on construction before comparing brands or sidewall details. On a car from this era, the tire contributes strongly to stance, wheel opening fill, and overall authenticity of presentation.

Yes, modifications can affect tire fitment on a 1957 Plymouth Plaza & Savoy even when the tire size itself is one of the correct primary options. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body work can all influence how a 750-14 or 800-14 tire sits and clears the car.

That is especially important on an older vehicle that may have changed hands and configurations more than once. A quick check of wheel diameter, wheel width, steering clearance, and fender space helps confirm whether the car still suits its original-style fitment or whether extra caution is needed. Any move to a radial equivalent should be treated the same way, with the current setup verified before tire selection.

Before driving a 1957 Plymouth Plaza & Savoy on new tires, inspect the wheels for proper diameter and general condition, confirm that the tires are mounted in the intended 750-14 or 800-14 size, and check inflation carefully. It also makes sense to look over the suspension and steering so the new tires are not being asked to work around worn components.

A slow first drive is the best way to confirm there is no rubbing, pulling, or unusual vibration once the car is back on the road. Sidewall clearance at full steering lock and adequate space under compression are worth checking on a car of this age. After the first miles, recheck air pressure and give the tires and wheels another visual inspection before settling into regular use.

Collector-car tires in 750-14 or 800-14 should be maintained with regular pressure checks, periodic visual inspection, and clean storage conditions. Even a lightly driven 1957 Plymouth Plaza & Savoy can develop tire issues over time if it sits for long periods, so tread condition, sidewall cracking, bulges, cuts, and unexplained air loss all deserve attention.

Storage habits matter almost as much as mileage on a vintage car. Keeping the Plymouth away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires while the car is parked. Occasional movement can also help prevent long-term flat spotting on collector vehicles. Before any longer drive, inspect the tires closely rather than assuming low annual mileage means they are automatically road-ready.
