1958 Plymouth Belvedere Tires

The 1958 Plymouth Belvedere uses two primary tire sizes: 750-14 and 800-14. Both are bias-ply sizes designed for 14-inch rims, so the fitment question is not about switching wheel diameter but about confirming which of the two primary sizes belongs on the car you are working with.

That distinction matters because 750-14 and 800-14 are both valid Belvedere sizes, but they are not the same tire. Before choosing a product, verify the wheel setup already on the car and compare the existing tire or restoration plan so the new set matches the intended appearance, wheel width, and overall fitment.

The tire fitments for the 1958 Plymouth Belvedere use a 14-inch rim diameter. Both 750-14 and 800-14 are built around that same 14-inch wheel size, which simplifies the basic wheel-diameter question even though the car has two different primary tire sizes.

Rim diameter is only the first check, though. A 14-inch wheel still needs to be evaluated for width before selecting among available tires or considering radial equivalents, especially on a collector car that may have had wheel changes over the years. Confirming both diameter and wheel width keeps the tire choice grounded in the actual setup.

The 1958 Plymouth Belvedere is associated with both 750-14 and 800-14 as primary tire sizes. Since both fitments are bias-ply and both use a 14-inch rim, the difference is centered on the tire size itself rather than on a change in construction type or wheel diameter.

That means owners should avoid assuming one size automatically replaces the other. The smart approach is to confirm which primary size matches the wheels and the car’s intended presentation, then compare products within that size. Once the correct primary size is settled, sidewall style, brand, and radial-equivalent options become much easier to narrow down.

For the 1958 Plymouth Belvedere, 750-14 is a primary bias-ply tire size. It is one of the two original-style fitment paths for this model, and it is offered in several bias-ply product lines with traditional sidewall treatments such as blackwall, narrow whitewall, wide whitewall, and redline.

That matters because a buyer choosing 750-14 is starting from a period-style construction, not a modern radial fitment. A radial equivalent can still be considered, but it should be evaluated separately by wheel width, overall dimensions, and clearance. Keeping that distinction clear helps avoid mixing original-style fitment with alternative construction choices.

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. The recommended rim-width range for these equivalents is 4 to 6 inches.

Each of those sizes approaches the original 750-14 fitment a little differently in sizing format and presentation. The metric and P-metric options use modern radial conventions, while 750R14 is aimed at owners who want a more traditional visual character. Wheel width, actual tire dimensions, and body or steering clearance should still be checked before making the switch.

Start by confirming which primary Belvedere size the car uses, because the radial equivalents differ between 750-14 and 800-14. Then confirm the wheel diameter, the actual wheel width, and the equivalent size you are considering, since the recommended rim-width ranges are 4 to 6 inches for 750-14 equivalents and 5 to 7 inches for 800-14 equivalents.

A conversion should also include a careful clearance review at the fenders, steering, and suspension. Cars that have been lowered, fitted with aftermarket wheels, or altered during restoration deserve extra attention. The goal is to confirm that the radial alternative suits the complete wheel-and-vehicle setup, not just the original size designation.

The first consideration is making sure 750-14 is the correct primary size for the specific 1958 Plymouth Belvedere being fitted. Once that is established, selection comes down to construction style, brand, tire series, sidewall treatment, rim-width compatibility, and details such as maximum load figures where they are shown.

In this size, the visible character of the tire can change the look of the car just as much as the brand name. Blackwall, narrow whitewall, wide whitewall, and redline options create very different presentations, so the right choice depends on whether the Belvedere is being restored toward a period-style appearance or prepared for a different visual direction.

1958 Plymouth Belvedere tires are available with several sidewall styles, including blackwall, narrow whitewall, and wide whitewall. In 750-14, redline is also available, giving that size an extra appearance option beyond the more traditional blackwall and whitewall treatments.

Sidewall choice can dramatically affect how a late-1950s Plymouth reads visually, even when the tire size stays the same. A wide whitewall leans into the period look associated with the era, while blackwall offers a plainer presentation and redline adds a more distinctive accent. The key is to choose the style that matches the car’s overall restoration theme.

The 1958 Plymouth Belvedere has tire options from BFGoodrich, Firestone, Goodyear, US Royal, Coker Classic, and Universal Vintage Tire. Those brands appear across the two primary bias-ply sizes and are spread among several classic-style tire series rather than one uniform product family.

That variety gives owners room to compare more than just brand names. Sidewall style, tire series, rim-width specification, weight, and stated load figures may differ by size and product, so the strongest comparison starts with the correct Belvedere size first. After that, the best choice is the one that matches the car’s appearance goals and wheel setup.

A period-style 1958 Plymouth Belvedere should start with one of its two primary bias-ply sizes, 750-14 or 800-14, depending on which size matches the car. That keeps the selection anchored in the Belvedere’s original fitment style before moving into appearance details such as blackwall, narrow whitewall, wide whitewall, or redline in the applicable size.

The visual goal should guide the final choice within that size. Late-1950s American cars often carry a very different character depending on sidewall treatment, and the Belvedere is no exception. Owners pursuing exact historical authenticity should also compare the chosen tire against marque references or restoration documentation before settling on a final brand or sidewall style.

On a restored 1958 Plymouth Belvedere, tire construction affects both visual stance and overall presentation. The primary fitments are bias-ply, which is the traditional construction associated with the car’s original era, while radial equivalents introduce a more modern format even when they are selected to stay close to the original size.

That difference matters most when the restoration goal is period-style character. A standard radial can change the look as well as the construction, while a bias-look radial is aimed at owners who want a more traditional appearance with radial construction. Either way, the result should be judged against the car’s restoration priorities, not construction alone.

Yes, modifications can affect tire fitment on a 1958 Plymouth Belvedere even when the tire size itself is correct. Aftermarket wheels, wheel-width changes, altered offset, lowering, suspension work, or body repairs can all change how a 750-14, 800-14, or radial-equivalent tire sits within the wheel opening and steering arc.

A car that has been updated should be checked as an individual setup rather than treated like a stock Belvedere. Wheel diameter, wheel width, and clearance at the fenders and steering components are all worth verifying before mounting a new set. That is especially important when moving from bias-ply to radial construction or between the two primary sizes.

Before driving a 1958 Plymouth Belvedere on new tires, inspect the wheels for correct diameter and sound condition, confirm proper tire pressure, and look over the suspension and steering for obvious wear. The new tires should also be checked for clearance at full steering lock and through normal suspension travel.

A collector car that has spent long periods parked deserves extra attention beyond the tires alone. Hardened wheel hardware, aged valve components, uneven ride height, or old alignment issues can all affect how the car behaves once it returns to the road. A careful once-over helps the new tires perform as intended and protects the fitment decision.

Collector-car tires in 750-14 or 800-14 size should be maintained with regular pressure checks, visual inspections, and attention to age-related condition even if tread wear is minimal. Sidewall cracking, bulges, cuts, flat spotting, and slow air loss all matter on a 1958 Plymouth Belvedere that may spend more time stored than driven.

Good storage habits also make a difference. Keeping the Belvedere away from prolonged sun, excess heat, moisture, and ozone sources helps preserve the tires between drives. Occasional movement can help reduce prolonged static loading, and any tire that shows visible deterioration should be evaluated before the car goes back into regular road use.
