1958 Plymouth Plaza & Savoy Tires

The 1958 Plymouth Plaza & Savoy uses either 750-14 or 800-14 as its primary tire size, and both are bias-ply fitments on 14-inch rims. Those are two distinct original-style size paths for this exact model, so the car should not be treated as having just one universal size.

The practical next step is checking which size is already on the vehicle, confirming the wheel width, and deciding whether the goal is a period-style bias-ply replacement or a radial-equivalent alternative. If the car has been changed over the years, the existing wheel-and-tire setup matters more than assumptions based only on the model name.

The 1958 Plymouth Plaza & Savoy uses a 14-inch rim with both of its primary tire sizes, 750-14 and 800-14. Rim diameter stays the same across these fitments, even though the tire size itself can vary.

That makes the diameter question straightforward, but wheel width still matters when choosing among available tires or considering a radial equivalent. A car that still has its original-style wheels may be simple to sort out, while a car with replacement wheels should be measured and inspected before a new set of tires is selected.

The 1958 Plymouth Plaza & Savoy is associated with two primary tire sizes, 750-14 and 800-14, both in bias-ply construction. That means tire selection depends on the actual wheel-and-tire setup on the car rather than assuming one size applies to every example in the same way.

A collector car may have changed wheels, replacement tires, or an earlier restoration that chose one size over the other for appearance or stance. Matching the existing fitment, checking the wheel width, and looking at clearance around the fenders and steering components will help narrow the choice to the size that makes sense for that specific car.

For the 1958 Plymouth Plaza & Savoy, 750-14 is a primary bias-ply tire size. It uses the traditional numeric bias-ply sizing format, and that construction is part of the car’s original-era tire character and appearance.

A buyer choosing 750-14 usually decides next whether to stay with a bias-ply tire for period-style presentation or consider one of the available radial equivalents. If the car will be converted to a radial alternative, compare the wheel width, overall dimensions, and clearance carefully rather than assuming every 14-inch option behaves the same on the vehicle.

For 750-14, radial equivalents include 195R14, P205/75R14, P215/70R14, and the bias-look radial 750R14. For 800-14, the corresponding equivalents are 205R14, P215/75R14, P225/70R14, and the bias-look radial 800R14. These give the 1958 Plymouth Plaza & Savoy both metric and P-metric radial alternatives, plus a radial option with a more traditional visual presentation.

Each equivalent uses a different sizing convention, so the decision is not just radial versus bias-ply. Rim-width guidance, wheel compatibility, and clearance around the body and steering should all be reviewed before making the switch, especially on a restored car where appearance and stance may matter as much as the change in tire construction.

Start by confirming whether the car uses 750-14 or 800-14, then compare that size to the appropriate radial equivalent rather than choosing a radial by rim diameter alone. For this Plymouth, the available radial alternatives include 195R14, P205/75R14, P215/70R14, 750R14, 205R14, P215/75R14, P225/70R14, and 800R14, depending on the original bias-ply size.

Wheel width is one of the first checks, along with clearance at the fenders, steering, and suspension. A radial conversion can also change the visual character of the car, so owners pursuing a restoration-oriented look often compare a standard radial alternative against a bias-look radial before deciding which direction suits the vehicle best.

Begin with the correct primary size for the car, since the 1958 Plymouth Plaza & Savoy can use either 750-14 or 800-14 and both are bias-ply fitments. Once the size is confirmed, the real comparison becomes construction choice, wheel-width compatibility, sidewall style, brand, and the visual character you want the tire to bring to the car.

A period-style restoration may lean toward a traditional bias-ply with the right whitewall treatment, while a driver-focused build may lead you to study the radial equivalents more closely. Checking the existing wheels, the car’s stance, and how much emphasis is placed on original-era appearance will usually narrow the field quickly.

Available sidewall styles for 1958 Plymouth Plaza & Savoy tires include blackwall, narrow whitewall, wide whitewall, and redline, depending on the size and product line. The broadest appearance range is in 750-14, while 800-14 is also offered in blackwall, narrow whitewall, and wide whitewall treatments.

That choice has a major effect on how the car presents, especially on a late-Fifties Plymouth where the sidewall is highly visible. A blackwall gives a plainer look, while narrow and wide whitewalls change the car’s period-style emphasis. Redline is also available in 750-14 for buyers who want a more distinctive vintage performance flavor.

Brands available for the 1958 Plymouth Plaza & Savoy include BFGoodrich, US Royal, Firestone, Goodyear, Coker Classic, and Universal Vintage Tire. Availability varies by size, with 750-14 showing the widest mix of brands and 800-14 centered on BFGoodrich, Goodyear, and Universal Vintage Tire offerings.

Brand should be considered alongside the tire series, sidewall treatment, and wheel-width specification rather than as a stand-alone choice. Two tires may share the same size but present the car very differently, so comparing the overall appearance and fitment details is usually more useful than choosing only by the name on the sidewall.

A period-style 1958 Plymouth Plaza & Savoy usually starts with the correct primary bias-ply size for the individual car, either 750-14 or 800-14. From there, the appearance decision often centers on blackwall, narrow whitewall, or wide whitewall, with 750-14 also offering a redline option for a different vintage look.

Bias-ply construction generally preserves the most traditional presentation, especially on a full-size late-Fifties Plymouth where the tire profile and sidewall treatment are visually important. When exact originality matters, it is worth checking marque-specific restoration references or historical vehicle documentation before settling on one stripe or whitewall treatment.

Correct tire fitment matters a great deal on a 1958 Plymouth Plaza & Savoy restoration because the car’s proportions, ride height impression, and sidewall presentation are all strongly influenced by the tire. Using the proper size family, 750-14 or 800-14, keeps the restoration grounded in the vehicle’s actual fitment range.

Appearance is only part of the picture, since wheel width and tire construction also affect what can be used safely and sensibly on the car. A restoration-oriented buyer should compare the existing wheel setup, decide whether bias-ply character is important to the finished look, and treat radial equivalents as alternatives that still require careful checking.

Yes, modifications can affect tire fitment on a 1958 Plymouth Plaza & Savoy even when the car still uses a 14-inch wheel. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or body repairs can influence how either a 750-14 or 800-14 tire sits in the wheel opening and clears adjacent components.

That is especially important when moving to a radial equivalent, since the construction and sizing format may differ from the original bias-ply tire. Measuring the actual wheel, checking steering travel, and inspecting fender and suspension clearance will give a much better answer than relying on size designation alone.

Before driving a 1958 Plymouth Plaza & Savoy on new tires, inspect the wheels for condition and correct diameter, confirm lug hardware and mounting surfaces, and make sure the tires are inflated properly for the application. It also helps to check that the chosen 750-14 or 800-14 tires clear the fenders, steering components, and suspension through normal movement.

A short, careful road test is a smart follow-up after installation, especially on a collector car that may have sat for long periods. Listen for rubbing, watch for pull or vibration, and recheck pressure after the first few drives. Any sign of interference or unusual wear should be addressed before regular road use.

Collector-car tires on a 1958 Plymouth Plaza & Savoy should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the car uses 750-14 or 800-14 tires, look for cracking, bulges, cuts, uneven wear, and slow air loss, especially if the car is driven only occasionally.

Storage conditions matter just as much as mileage on an older vehicle. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and periodic movement can reduce flat-spotting during long storage. Before any longer drive, inspect the full tread and sidewall area rather than judging condition by appearance alone.
