1958 Rambler Tire Fitment Guide

1958 Rambler vehicles use five sizes across four models: 800-14 for the Ambassador, 590-15 and 640-15 for the American, 640-15 and 670-15 for the Rambler, and 750-14 for the Rebel. Those fitments are all bias-ply sizes, and they are split between 14-inch and 15-inch wheel diameters. Where rim-width guidance is listed, 800-14 fits 5.00-6.00-inch rims, 590-15 fits 4.00-4.50-inch rims, 640-15 fits either 4.00-4.50-inch or 4.50-5.00-inch rims depending on product, 670-15 fits either 4.50-5.00-inch or 5.00-6.00-inch rims, and 750-14 fits 5.00-5.50-inch rims.

Model identification matters first on a 1958 Rambler because the lineup does not share one universal tire size. Once the model and wheel diameter are confirmed, the next step is narrowing by the exact size used on that model and then choosing the sidewall style that matches the car's character, whether that means blackwall, narrow whitewall, wide whitewall, or redline where available.

On a 1958 Rambler, 800-14 is a numeric bias-ply tire size. The 800 identifies the tire's nominal section-width class in vintage numeric sizing, and the 14 means it mounts on a 14-inch wheel. It is not a modern metric size, and it does not decode the same way a P-metric or radial size would. For the 1958 Rambler line, 800-14 belongs specifically to the Ambassador.

That matters because a buyer looking at a 14-inch Rambler tire may still have two very different size families in play depending on model. The Ambassador's 800-14 and the Rebel's 750-14 are both 14-inch fitments, but they are not interchangeable by assumption. Matching the full size code, not just the rim diameter, is the right approach when selecting a reproduction bias-ply tire.

No, 1958 Rambler models do not all use the same tire size. The Ambassador uses 800-14, the American uses 590-15 and 640-15, the Rambler uses 640-15 and 670-15, and the Rebel uses 750-14. Only 640-15 is shared, and even that applies only to the American and Rambler models rather than to the whole make.

That means year and make alone are not enough for confident tire selection on a 1958 Rambler. A buyer should confirm whether the car is an Ambassador, American, Rambler, or Rebel before comparing products. Once the model is settled, the correct size range becomes much clearer and helps prevent mixing a 14-inch fitment with a 15-inch application or choosing a shared size that belongs to a different model.

1958 Rambler tire choices include several period-style sidewall treatments, depending on size. Blackwall appears in 800-14, 590-15, 670-15, and 750-14 offerings, narrow whitewall appears in 800-14, 640-15, and 750-14, wide whitewall appears in every size family represented here, and redline appears in 750-14. That range reflects the visual diversity of the late 1950s, when whitewalls were widely associated with upscale presentation and sportier accents were beginning to show up on certain cars.

A restoration-focused buyer should usually choose the sidewall look that matches the car's intended market image and presentation style rather than selecting by appearance alone. Wide whitewalls tend to suit a dressed-up late-1950s American car, while blackwalls deliver a plainer, more utilitarian look. The Rebel's redline option is especially distinctive, but the best match still comes from pairing the correct size to the correct model before deciding which sidewall treatment looks right.

Brands represented across 1958 Rambler sizes include BFGoodrich, Universal Vintage Tire, Avon, Firestone, US Royal, and Coker Classic. The brand mix changes by size: 800-14 comes from BFGoodrich and Universal Vintage Tire, 590-15 from BFGoodrich and Avon, 640-15 from BFGoodrich and Firestone, 670-15 from Firestone, US Royal, Coker Classic, and Universal Vintage Tire, and 750-14 from BFGoodrich, US Royal, and Coker Classic. Not every brand appears in every Rambler fitment.

Brand choice on a 1958 Rambler is usually less about changing the basic fitment and more about choosing among sidewall styling, listed load figures, and the visual character associated with a given series. A buyer comparing brands should stay inside the exact size required for the model first, then compare the appearance and specifications of the available products within that size rather than assuming the same brand lineup carries across the whole Rambler range.

In 1958 Rambler 590-15 fitment, BFGoodrich offerings include blackwall and wide whitewall versions of a bias-ply tire with listed rim-width guidance of 4.00-4.50 inches and a stated load figure of 1050 pounds at 32 psi. The Avon Turbospeed in the same size is also listed as bias ply, uses a blackwall appearance, carries an H speed rating with a 130 mph ceiling, and lists a maximum load of 1,018 pounds. The Avon entry is also lighter in listed weight than the BFGoodrich versions.

That comparison gives a 1958 Rambler American owner two different paths inside the same size family. BFGoodrich offers the broader sidewall-style choice for a more traditional late-1950s look, while Avon brings a speed-rated option in blackwall form. The right call depends on whether the car's presentation matters most or whether you want the specific characteristics tied to that Avon-marked product.

Rim-width guidance for 1958 Rambler tires depends on the size. The 800-14 size is listed for 5.00-6.00-inch rims, 590-15 for 4.00-4.50-inch rims, 640-15 for either 4.00-4.50-inch or 4.50-5.00-inch rims depending on the product, 670-15 for either 4.50-5.00-inch or 5.00-6.00-inch rims depending on the product, and 750-14 for 5.00-5.50-inch rims. Those ranges should be checked against the actual wheel on the car rather than assumed from model name alone.

That is especially important where one size includes more than one approved rim-width range. A 1958 Rambler owner comparing two products in the same size may find that both fit the model but call for slightly different wheel widths. Confirming the wheel before purchase helps avoid a mismatch between the tire's approved mounting range and the rim already on the vehicle.

The available 1958 Rambler tire listings do not carry tube-type or tubeless markings across these products, so tube choice should be confirmed from the specific tire and wheel combination you plan to use. That matters because a vintage-style bias-ply tire can be mounted in more than one wheel environment depending on the vehicle's original wheel design and the details of the reproduction tire selected.

A practical way to approach a 1958 Rambler is to inspect the wheels already on the car and verify the sidewall markings on the exact product before finalizing setup parts. If the car still uses original-style wheels, many owners also check the condition of the valve stem area and the inside of the rim at the same time, since an otherwise correct tire installation can still be compromised by aged wheel hardware or corrosion.

A 1958 Rambler should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate rubber aging. Keeping the tires clean and properly inflated helps them hold shape during long periods of inactivity. Because every fitment here is bias ply, the tires are more prone to temporary flat-spotting during storage than a modern radial would be.

For a collector Rambler that sits for weeks or months at a time, periodic rolling or repositioning is helpful, and some owners use stands to reduce static load during longer storage periods. Tire covers can also help limit UV exposure if the car is kept in a bright area. Good storage habits preserve sidewall appearance and reduce the chances of vibration or harsh ride feel on the next outing.

Tire life on a 1958 Rambler is usually judged more by age than mileage. Collector vehicles often accumulate limited miles, so a tire can look usable in tread depth while still aging out in the rubber. A sound rule is to begin evaluating closely once tires are around five to seven years old and to treat roughly ten years as a serious replacement consideration, regardless of how little the car has been driven.

The smartest check is the date code on each tire, along with a close look at sidewall cracking, hardening, irregular wear, and how well the tire holds pressure over time. A lightly used Rambler that spends most of its life indoors may age more gracefully than one stored outside, but age still matters. Time, environment, and care usually tell you more than odometer readings on a vintage car.

Tires on a 1958 Rambler should be inspected before every drive, especially if the car is used intermittently. Look for sidewall cracks, bulges, cuts, embedded debris, uneven tread wear, and any sign that a tire has lost pressure since the last outing. Bias-ply tires reward regular inspection because many collector cars spend long periods parked and then go directly onto the road without the daily-use checks a modern driver might take for granted.

A more thorough inspection before longer trips is wise, including the spare, wheel condition, and valve stems. If the car uses an inner-tube setup, tube-related leaks often show up first as slow pressure loss rather than obvious visual damage. Building a habit of quick pre-drive checks is one of the easiest ways to keep a 1958 Rambler dependable and pleasant on short cruises or extended event drives.

A 1958 Rambler Ambassador in this fitment family uses 800-14, and the period-correct construction for a 1958 American car is bias ply. That aligns with the broader industry reality of the late 1950s, when bias-ply tires were still standard equipment on domestic passenger cars. Original-equipment brand varied by manufacturer practice, assembly sourcing, and market, so the important restoration point is matching the correct size, construction type, and sidewall character first.

For a judged restoration, owners usually confirm the final sidewall treatment and any market-specific details through factory literature, marque clubs, and period photographs of similarly equipped cars. The same approach applies across the 1958 Rambler line, whether the car is an American, Rambler, Rebel, or Ambassador. Getting the size family right establishes the foundation; the finishing touches come from choosing the correct visual treatment for the way the car is being restored.

Correct tire fitment matters a great deal when showing a 1958 Rambler because judges and knowledgeable enthusiasts notice size, construction, and sidewall style quickly. A car wearing the wrong wheel diameter, an incorrect size family for its model, or a sidewall treatment that clashes with the period look can stand out even if the rest of the restoration is strong. Late-1950s American cars are especially sensitive to whitewall presentation, since the tire's visual impact is such a visible part of the finished profile.

That does not mean every event uses the same standard, but it does mean authenticity-minded owners should choose tires with the same care they would give paint, trim, or wheel covers. A local cruise night may welcome more freedom than a marque-specific judged event. Checking club guidance and event rules beforehand helps determine whether a blackwall, narrow whitewall, wide whitewall, or redline treatment is the most credible match for a particular 1958 Rambler.

For 1958 Rambler 640-15 fitment, BFGoodrich appears as a wide whitewall option with a listed rim-width range of 4.00-4.50 inches and a stated load figure of 1190 pounds at 32 psi. Firestone offerings in the same size include two wide whitewall versions and one narrow whitewall version, with listed rim-width guidance of 4.50-5.00 inches. Firestone also lists two different load figures in this size family, including 1190 pounds at 32 psi and 970 pounds at 32 psi depending on the specific product.

That means a 1958 Rambler American or Rambler owner comparing 640-15 products should look beyond the size stamp alone. Sidewall appearance, wheel-width compatibility, and the listed load figure all vary inside the same size family. For a restoration, the visual difference between narrow and wide whitewall may be the deciding factor, while a careful fitter will also confirm that the wheel on the car matches the approved rim-width range of the chosen tire.

1958 Rambler tires can be suitable for highway use when they are the correct size for the model, properly installed, correctly inflated, and in sound condition. Every size here is a bias-ply fitment, and one 590-15 option from Avon carries an H speed rating with a 130 mph ceiling. Most of the other products do not show a speed letter, so a buyer should not assume a shared speed capability across every Rambler tire offering.

On a car of this age, the tire is only one part of the highway-readiness question. Brakes, steering, wheel bearings, suspension condition, and alignment matter at least as much as the tire itself. A well-sorted 1958 Rambler on fresh, correctly sized tires can be an enjoyable road car, but the right approach is to think of highway safety as a complete vehicle-condition issue rather than a tire label alone.

Several 1958 Rambler tire sizes list maximum load at 32 psi, including 800-14 at 1620 pounds, 590-15 at 1050 pounds on BFGoodrich products, 640-15 at 1190 pounds or 970 pounds depending on product, 670-15 at 1450 or 1550 pounds depending on product, and 750-14 at 1500 or 1580 pounds depending on product. Those figures identify the pressure associated with the stated maximum load on that particular tire. They are not automatically the same as the vehicle manufacturer's recommended operating pressure.

For a 1958 Rambler, the best practice is to start with the original owner's manual or factory inflation guidance for the specific model, then compare it with the tire maker's information for the exact product you are using. Pressure should never be transferred casually from one Rambler size to another, especially when the car could be on either 14-inch or 15-inch wheels and several different load-rated products exist within the lineup.

Before a longer drive in a 1958 Rambler, inspect each tire for cracking, cuts, bulges, tread damage, and pressure loss, and make sure the spare is usable as well. Confirm that the tires match the correct model-specific size, since the 1958 Rambler range spans both 14-inch and 15-inch applications. Any vibration, pull, or unusual wear pattern should be addressed before departure rather than treated as a normal old-car quirk.

A longer-trip check should also include the broader chassis and braking systems because a late-1950s car asks more of its mechanical condition than a modern driver may expect. Wheel bearings, brake function, steering play, and fluid levels all matter, but the tires remain the first road contact point. A few minutes of inspection before departure can prevent turning a pleasant Rambler drive into a preventable roadside problem.
