1958 Mercury All Models Except: Tires

The primary tire size for the 1958 Mercury All Models Except: is 800-14. This is a vintage numeric bias-ply size used on a 14-inch rim, and the covered Base sub-model uses that same fitment.

That means the main choice is not between multiple primary sizes, but between the available tires within 800-14 and any radial-equivalent alternatives you may want to consider. Before ordering, confirm that the car still has the correct wheel diameter and that no later wheel, brake, or suspension changes have altered the fitment requirements.

The 1958 Mercury All Models Except: uses a 14-inch rim with its primary 800-14 tire size. Product offerings in this fitment also show rim-width compatibility in the traditional range used with this size, depending on the specific tire selected.

Rim diameter is the first thing to confirm because an 800-14 tire is built for a 14-inch wheel, not a different diameter. On an older Mercury, it is also smart to verify the actual wheel width currently on the car, especially if it has been restored, modified, or fitted with replacement wheels over the years.

Yes. The covered 1958 Mercury All Models Except: Base uses the same 800-14 bias-ply tire size as the overall fitment for this vehicle grouping. There is no separate primary size within the covered sub-model information.

That keeps the fitment side simple, but it does not make every tire choice identical. Owners still need to decide whether they want a blackwall, narrow whitewall, or wide whitewall appearance, and whether staying with a traditional bias-ply construction or exploring a radial equivalent better matches the car’s restoration goals and driving plans.

For the 1958 Mercury All Models Except:, 800-14 is the primary bias-ply tire size. The available products in that primary size are bias-ply tires, which match the original-era sizing format and traditional tire presentation associated with a late-1950s full-size Mercury.

That matters because staying with bias-ply keeps the car in its original construction family, while moving to a radial means selecting an equivalent rather than the primary fitment itself. Construction changes should be evaluated alongside wheel width, overall tire dimensions, and clearance, especially on a large collector car that may have seen wheel or suspension changes during its life.

Radial equivalents for 800-14 include 205R14 as an 80-series metric radial, P215/75R14 as a 75-series P-metric radial, P225/70R14 as a 70-series P-metric radial, and 800R14 as a bias-look radial. These are alternatives to the original bias-ply size, not additional primary fitments.

Each option follows a different sizing convention, so the practical decision is not just radial versus bias-ply, but which radial format best suits the car and wheel setup. A 5-7 inch recommended rim-width range is associated with these equivalents, and wheel width, diameter, and vehicle clearance should be confirmed before making the change.

Yes, 800R14 is available as a bias-look radial equivalent for the 1958 Mercury All Models Except:. It is intended for owners who want a radial alternative while keeping a more traditional visual presentation than a clearly modern metric-marked replacement might suggest.

A bias-look radial still needs the same careful fitment review as any other equivalent size. The wheel diameter must remain 14 inches, rim width should fall within the appropriate range, and the overall tire dimensions and clearance around the fenders and suspension should be checked before committing to a construction change.

Start with the correct primary size, which is 800-14, and then narrow the choice by construction, sidewall appearance, brand, and tire series. In this fitment, the available products are bias-ply tires, so the main variations are visual style and the specific product family rather than a mix of primary constructions.

A restoration-minded Mercury may call for a wide whitewall or narrow whitewall, while a more understated presentation may point to a blackwall. It also helps to compare rim-width compatibility, load figures where stated, and the intended use of the car, since a lightly driven show car and a regularly road-driven collector car may lead to different priorities.

The available 800-14 tires for the 1958 Mercury All Models Except: come in blackwall, narrow whitewall, and wide whitewall styles. That gives owners a meaningful appearance choice without changing the primary tire size itself.

Sidewall style has a major effect on how a late-1950s Mercury looks, especially because these cars carry a lot of visual mass and chrome. The best choice depends on the character you want the car to present, whether that is cleaner and more restrained or more overtly period-styled, while still keeping the correct 800-14 fitment at the center of the decision.

BFGoodrich, Goodyear, and Universal Vintage Tire all offer 800-14 tires for the 1958 Mercury All Models Except:. Those options appear across tire series including Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply.

Brand is only one part of the selection process on a car like this. It is also worth comparing the sidewall treatment, the product series character, and wheel compatibility details such as rim-width specification, since two tires in the same size can still serve different restoration or presentation goals even before radial-equivalent options enter the conversation.

A period-style starting point for the 1958 Mercury All Models Except: is the original-format 800-14 bias-ply size. Within that size, the visual direction comes from the sidewall treatment and tire series rather than from changing to a different primary fitment.

Wide whitewall, narrow whitewall, and blackwall options can all change the car’s presentation in noticeable ways. If exact restoration authenticity matters, the final appearance choice should be checked against marque references, period photos, or vehicle-specific documentation, because a tire that suits the era well is not automatically the exact original style for every individual Mercury.

Tire construction affects both the look and character of a restored 1958 Mercury All Models Except:. The primary 800-14 bias-ply format delivers the traditional sizing language and period-style presence most owners expect on a late-1950s full-size American car.

A radial equivalent can change the visual impression even when it stays close to the original fitment intent, especially if the replacement uses modern metric sizing. An 800R14 bias-look radial can help bridge that gap for owners who want a more vintage presentation, but wheel size, width, and overall fit should still be verified before making the switch.

Yes, modifications can affect tire fitment on a 1958 Mercury All Models Except:, even when the original tire size is straightforward. Changes such as aftermarket wheels, altered wheel width, suspension work, lowering, or brake conversions can all change the space available for an 800-14 tire or any radial-equivalent alternative.

That is why the actual car should be checked before replacing old tires based only on year and model. Wheel diameter needs to remain correct, and the combination of width, offset, steering travel, and fender clearance should be reviewed carefully, particularly if the Mercury has been restored more than once or modified at any point in its history.

Before putting a 1958 Mercury All Models Except: back on the road, inspect the wheels, valve stems, and the tire mounting itself, then confirm that all four tires are the intended size and properly inflated for the setup being used. It is also smart to look over steering and suspension components on a long-stored collector car.

A fresh set of tires can only do its job if the surrounding hardware is sound. Check for rubbing at full steering lock, make sure the wheels are true and free of damage, and verify that brakes, alignment, and suspension condition are not likely to create uneven wear or road manners that get blamed on the tires.

800-14 tires on a collector 1958 Mercury All Models Except: should be kept at the proper operating pressure for the tire and vehicle setup, inspected regularly for cracking, cuts, bulges, and air loss, and stored away from prolonged sunlight, heat, moisture, and ozone sources when the car is not being driven often.

Collector cars frequently age their tires through time and storage rather than mileage alone. Routine checks matter even when tread wear looks minimal, and the car should be looked over before longer drives after sitting. Consistent maintenance protects both the tire investment and the fitment confidence needed for a large, heavy late-1950s road car.
