1958 Rambler Ambassador Tires

The 1958 Rambler Ambassador uses an 800-14 tire size. This is a numeric bias-ply fitment for a 14-inch rim, and the covered 8 Cyl. sub-model uses that same primary size, so the fitment question is more straightforward than on vehicles that changed sizes by trim or wheel package.

Once the size is confirmed, the real decision becomes which version of 800-14 best suits the car. Available tires vary by brand, tire series, and sidewall treatment, including blackwall, narrow whitewall, and wide whitewall styles. It is also worth verifying that the car still has its intended wheel setup if wheels were changed at some point.

The 1958 Rambler Ambassador uses a 14-inch rim with its primary 800-14 tire size. That rim diameter is central to fitment because both the original bias-ply size and its radial-equivalent alternatives are built around the same 14-inch wheel diameter.

Rim diameter alone is not the only measurement that matters. Wheel width should also be checked before choosing among available tires or considering a radial equivalent, especially on a collector car that may have had replacement wheels installed over the years. Confirming the actual wheel on the car helps avoid clearance or mounting issues later.

Yes. The covered 1958 Rambler Ambassador 8 Cyl. uses the same 800-14 bias-ply tire size as the main fitment for this model. There is no separate primary size for that sub-model in the covered fitment, which simplifies the first step of selecting tires.

That consistency means most buyers can focus on construction and appearance rather than sorting through multiple factory-type sizes. The main differences come from the tire itself, such as blackwall versus whitewall styling, brand, and tire series. Checking the wheel dimensions on the actual car still matters, particularly if the car has been modified or restored with non-original wheels.

For the 1958 Rambler Ambassador, 800-14 is the primary bias-ply tire size. That means the original fitment format centers on traditional bias-ply construction rather than a modern radial as the starting point for this vehicle.

Keeping a bias-ply tire usually appeals to owners who want the tall profile and traditional presentation associated with a late-1950s car. A radial can still be considered through an equivalent size, but the decision should include wheel width, overall fit on the car, and the kind of driving the Ambassador will actually see rather than treating the two constructions as automatically interchangeable.

Radial equivalents for 800-14 include 205R14, P215/75R14, P225/70R14, and 800R14. Those cover an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial option that keeps a more traditional visual character than a typical modern radial.

Each option stays in the 14-inch wheel family, but that does not make every choice automatic on every car. The recommended rim-width range tied to these equivalents is 5-7 inches, and buyers should also compare the actual wheel on the car, surrounding clearance, and the vehicle’s stance before moving away from the original bias-ply size.

Start by confirming the wheel diameter and width on the car, then compare the radial equivalent you are considering against the 800-14 primary fitment. For this Ambassador, radial alternatives include 205R14, P215/75R14, P225/70R14, and 800R14, with a 5-7 inch recommended rim-width range associated with the equivalents.

A careful conversion also includes checking front and rear clearance, steering travel, suspension condition, and the visual effect you want from the car. Some owners prefer to retain the traditional look of a bias-ply or choose a bias-look radial, while others accept a more modern appearance. The key is treating the change as a full fitment decision, not just a size-number swap.

The first step is staying with the correct 800-14 size and confirming that the car still has a 14-inch wheel setup compatible with that fitment. From there, the biggest differences among available tires involve construction, sidewall presentation, tire series, and brand rather than changes to the primary size itself.

A buyer choosing for a road-ready driver may focus on overall fit and whether to remain with bias-ply construction or explore a radial equivalent. A buyer choosing for presentation may care more about blackwall, narrow whitewall, or wide whitewall styling. Rim-width specifications and load figures are also worth comparing where they are stated for the individual tire.

The 1958 Rambler Ambassador’s 800-14 tire choices include blackwall, narrow whitewall, and wide whitewall sidewall styles. That variety matters on a late-1950s American car because the sidewall treatment changes the car’s overall visual balance almost as much as the wheel and hubcap combination.

Blackwall gives the most restrained look, while narrow whitewall and wide whitewall options move the presentation toward a stronger period-style appearance. The right choice depends on how the car is being restored or driven, not on a universal rule. Owners who care about exact historical presentation should compare the car’s trim, photos, and marque-specific references before settling on a sidewall style.

Tires for the 1958 Rambler Ambassador in 800-14 are available from BFGoodrich, Goodyear, and Universal Vintage Tire. Those brands appear across several product lines, including Silvertown Classic Bias Ply, Custom Super Cushion, and Universal Classic Bias Ply, giving buyers more than one way to approach the same basic fitment.

Brand is only one part of the decision. It helps to compare sidewall style, construction, stated rim-width compatibility, and load-capacity details where those figures are shown. Since this car uses a single primary size, the smartest comparison is between tire character and presentation within 800-14, not between unrelated sizes that could change the look or fitment of the car.

A period-style 1958 Rambler Ambassador usually starts with the original-format 800-14 bias-ply size. That size preserves the traditional profile associated with the car, and it is offered in several bias-ply series with appearance choices that range from blackwall to narrow whitewall and wide whitewall treatments.

The best period-style choice depends on the character of the specific car rather than one universal answer. A restrained driver may look right on blackwalls, while a more formal or highly detailed restoration may call for a whitewall presentation. When originality is especially important, historical photos and Rambler-specific reference material are useful final checks before making the appearance decision.

Tire construction changes the look of a restored 1958 Rambler Ambassador more than many buyers expect. An 800-14 bias-ply tire keeps the traditional construction associated with the car’s era, while a radial equivalent can alter the visual impression even when it remains on the same 14-inch wheel diameter.

That does not mean a radial is the wrong choice, only that the appearance goal should be clear before selecting one. A bias-look radial can help bridge that gap for owners who want a more traditional presentation with radial construction. Sidewall style still matters either way, so construction and whitewall choice should be considered together rather than as separate decisions.

Yes. Even though the 1958 Rambler Ambassador’s primary size is 800-14, modifications can change how that size or a radial equivalent works on the car. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body and brake modifications can all affect mounting suitability and surrounding clearance.

A car that has been restored or updated should be checked as it sits now, not as it may have left the factory decades ago. Measuring the actual wheel diameter and width is the first step, followed by checking steering clearance and fender space. That becomes especially important when moving from the original bias-ply fitment to any radial alternative.

Before road use, inspect the wheels for correct diameter and sound condition, confirm that the tires are seated properly, and check inflation, tread, and sidewalls. On a collector-era 1958 Rambler Ambassador, it is also smart to look over suspension and steering components so the new tires are not being asked to compensate for worn hardware.

A short initial drive should be followed by another look at air pressure and visible clearance around the front suspension, rear wheel openings, and full steering travel. Collector cars sometimes reveal problems only after they are back in motion. Catching rub marks, unusual pull, or vibration early helps protect both the new tires and the car.

800-14 tires on a collector 1958 Rambler Ambassador should be kept at the proper inflation for the tire and checked regularly for cracking, cuts, bulges, uneven wear, and slow air loss. Cars that spend long periods parked deserve closer attention because age and storage conditions can affect tire condition even when tread wear is minimal.

Storage habits matter as much as mileage on a low-use collector car. Keeping the vehicle away from prolonged sunlight, heat, moisture, and ozone sources helps protect the sidewalls over time. It also helps to inspect the tires before each outing and again before a longer trip, since a car that looks fine in storage may still have age-related issues worth catching early.
