1958 Chevrolet Tire Fitment Guide

1958 Chevrolet vehicles use three sizes across the model range: 750-14, 800-14, and 670-15. The 750-14 size applies to 1958 Chevrolet Chevrolet models, 800-14 applies to 1958 Chevrolet Chevrolet, Impala, and Wagon models, and 670-15 is the Corvette fitment. The two full-size Chevrolet sizes both mount on 14-inch rims, while the Corvette uses a 15-inch rim. Where rim-width guidance is available, 750-14 fits 5.00 to 5.50-inch rims, 800-14 fits 5.00 to 6.00-inch rims, and 670-15 appears on 4.50 to 5.00-inch or 5.00 to 6.00-inch approved widths depending on the tire.

The practical takeaway is that year and make alone are not enough for 1958 Chevrolet fitment. Start by identifying whether the car is a full-size Chevrolet, an Impala, a Wagon, or a Corvette, then confirm the wheel diameter already on the car before narrowing the sidewall style. That avoids the common mistake of comparing 14-inch full-size tires to the Corvette’s 15-inch fitment as though they were interchangeable choices.

A 750-14 marking on a 1958 Chevrolet tire is a traditional numeric bias-ply size. The 7.50 figure is the nominal section width expressed in inches, and the 14 identifies the wheel diameter in inches. On 1958 Chevrolet applications, 750-14 is a 14-inch bias-ply fitment associated with Chevrolet passenger-car models rather than Corvette. It is available with multiple sidewall looks, including narrow whitewall, wide whitewall, and redline.

That older numeric code does not translate directly to a modern metric size by label alone, so the best approach is to stay with the original-style numeric size when originality matters. For a 1958 Chevrolet owner, the important part is recognizing that 750-14 is not just a generic old-car marking; it identifies a specific 14-inch bias-ply fitment within the broader Chevrolet line. Once that is confirmed, sidewall styling becomes the next restoration decision.

No, 1958 Chevrolet models do not all use the same tire size. Full-size Chevrolet applications appear in 750-14 and 800-14, while the 1958 Chevrolet Corvette uses 670-15. That means there is both a size split within the passenger-car lineup and a separate wheel-diameter break between full-size Chevrolet models and Corvette. Impala and Wagon models align with 800-14 rather than the Corvette’s 15-inch fitment.

For a buyer, that means the first step is positively identifying the model before choosing a tire. A full-size 1958 Chevrolet may still need a second check to determine whether it belongs in 750-14 or 800-14, especially if wheels have been changed over the years. Corvette owners have a clearer path because the 670-15 fitment stands alone in the 1958 Chevrolet range.

1958 Chevrolet tires are offered in several period-style sidewall treatments depending on size. The 750-14 size is available in narrow whitewall, wide whitewall, and redline. The 800-14 size is offered in blackwall, narrow whitewall, and wide whitewall, while 670-15 for the 1958 Chevrolet Corvette appears in blackwall and wide whitewall. All of these options are bias-ply, so the visual difference comes from the sidewall presentation rather than a change in construction type.

That choice matters because sidewall style strongly influences the finished look of a late-1950s Chevrolet. Wide whitewalls often deliver the most overt period flavor on full-size cars, while blackwalls and redlines can steer the car toward a plainer or more sporting presentation. Owners chasing event-specific authenticity should compare the chosen style against period photography, factory literature, or a marque expert familiar with 1958 Chevrolet judging standards.

Several brands cover 1958 Chevrolet fitments. The 750-14 size is available from BFGoodrich, US Royal, and Coker Classic. The 800-14 size is available from BFGoodrich and Universal Vintage Tire, while the 670-15 Corvette size is offered by Firestone, US Royal, Coker Classic, and Universal Vintage Tire. All listed options are bias-ply tires matched to the original-style sizing conventions of the period.

Brand choice on a 1958 Chevrolet often comes down to which combination of sidewall style, brand heritage, and dimensional fit best matches the car’s intended finish. A restorer may care deeply about the period character suggested by a particular brand name, while a driver-focused owner may be more interested in approved rim-width range and available sidewall appearance. Comparing within the correct size first keeps that brand decision meaningful.

For a 1958 Chevrolet Corvette in 670-15, the Firestone offering listed here is a blackwall bias-ply tire rated at 1450 pounds at 32 psi, intended for 4.50 to 5.00-inch rims, and weighing 23 pounds. The Coker Classic 670-15 is a wide whitewall bias-ply tire rated at 1550 pounds at 32 psi, intended for 5.00 to 6.00-inch rims, and weighing 21 pounds. Both mount on 15-inch rims, but they differ in sidewall appearance, load figure, weight, and approved rim-width range.

That means the choice is not purely cosmetic. A Corvette owner should first verify the actual wheel width, since the approved rim ranges are not identical between those two 670-15 options. Once wheel width is confirmed, the decision becomes whether the car calls for a blackwall sports-car look or a more visually prominent whitewall presentation consistent with a different restoration goal.

Rim-width guidance for 1958 Chevrolet tires varies by size and, in one case, by product. The 750-14 size is intended for 5.00 to 5.50-inch rims. The 800-14 size is intended for 5.00 to 6.00-inch rims. In 670-15, some tires are approved for 4.50 to 5.00-inch rims, while others are approved for 5.00 to 6.00-inch rims, so Corvette wheel width needs extra attention before selecting a specific product.

That range matters because two tires with the same size code do not always share the same approved wheel-width window. On a 1958 Chevrolet, especially a Corvette, measuring the wheel and comparing it to the individual tire’s approved range is the safest way to narrow the field. That step helps preserve intended tire shape and avoids choosing a tire whose casing is not matched to the wheel already on the car.

Original 1958 Chevrolet wheels cannot be treated as universal across all three sizes because the model range uses two different rim diameters. The 750-14 and 800-14 sizes both mount on 14-inch rims for full-size Chevrolet applications, while the 670-15 Corvette size requires a 15-inch rim. Diameter alone prevents a direct crossover between the Corvette fitment and the full-size passenger-car fitments.

Within the 14-inch full-size Chevrolet group, the next check is wheel width rather than diameter. A car already using 14-inch wheels may still need verification against the specific tire’s approved rim-width range before moving between 750-14 and 800-14. Corvette owners should approach 670-15 separately and confirm that the individual tire selected matches the wheel width on the car.

A 1958 Chevrolet should be stored in a cool, dry, dark environment away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing equipment. Clean floors and stable temperature help preserve the rubber, and keeping the tires properly inflated reduces casing stress while parked. Because every listed 1958 Chevrolet fitment here is bias-ply, longer static storage can encourage temporary flat-spotting more readily than many modern radial owners expect.

For a collector car that sits often, periodic rolling helps change the tire’s contact patch and reduces the chance of one section carrying the load for months at a time. Some owners also use stands during long-term storage to ease weight on the tires and suspension. The goal is not just preserving tread, but preserving sidewall condition and roundness so the car drives smoothly when it returns to service.

Tires on a 1958 Chevrolet are usually judged more by age and condition than by mileage, because collector cars often accumulate limited use. A good working rule is to inspect closely once tires reach the five-to-seven-year range and to consider replacement around ten years regardless of remaining tread. The DOT date code on the tire is the starting point for age tracking, even on a car that has spent much of its life indoors.

A low-mileage bias-ply tire can still age out through hardening, cracking, or internal deterioration long before the tread looks worn. That is especially important on a 1958 Chevrolet that sees occasional weekend drives and long idle periods between outings. If the car’s history is unclear, age verification and a careful professional inspection should come before relying on the existing tires for regular road use.

Tires on a 1958 Chevrolet should be inspected before every drive and again before any extended outing. Look closely for sidewall cracking, cuts, bulges, uneven wear, embedded debris, and any sign that the tire is losing pressure. Because these are bias-ply collector-car fitments, also watch for changes in ride smoothness after storage that may point to persistent flat-spotting or casing issues.

Routine inspection is one of the simplest ways to prevent a roadside problem in an older car that may not be driven often. On a 1958 Chevrolet, it also helps catch age-related deterioration that can progress even while the car is parked. Include the spare in that routine, since an aged spare is often forgotten until it is needed most.

A 1958 Chevrolet Corvette would have been fitted in keeping with the bias-ply construction standard of the era, and the size used here is 670-15. That places the car on a 15-inch bias-ply fitment rather than the 14-inch sizes used across Chevrolet’s full-size passenger-car line. Available replacements today include blackwall and wide whitewall versions, which means the construction can remain era-appropriate while the visual finish is tailored to the car’s presentation.

For an owner seeking strict originality, the key factors are correct size, correct construction type, and an appropriate sidewall style for the way the car is being restored or judged. Original-equipment brand use could vary by market and production practice, so final concours-level verification is best checked against factory literature, marque experts, and Corvette judging resources. That extra step matters more than choosing by brand name alone.

Correct tire fitment does matter when showing a 1958 Chevrolet, especially in restoration classes where overall period accuracy is judged. Size, construction type, rim diameter, and sidewall style all contribute to whether the car looks and presents as it would have in the late 1950s. A Corvette wearing a 14-inch full-size Chevrolet tire size, or a passenger car wearing an obviously incorrect sidewall treatment for the class, would stand out immediately.

The level of scrutiny depends on the event. Some local shows focus mostly on presentation, while marque judging may look much more closely at whether the tire’s visual character suits the specific model. Before committing to a tire for a show car, compare your intended class rules with period photos and 1958 Chevrolet club guidance so the final choice supports the way the vehicle will actually be judged.

On a 1958 Chevrolet restoration, 750-14 and 800-14 are both 14-inch bias-ply sizes, but they are not interchangeable by assumption because they apply to different parts of the full-size lineup. The 750-14 size appears on Chevrolet models and is approved for 5.00 to 5.50-inch rims, while 800-14 is used on Chevrolet, Impala, and Wagon applications and is approved for 5.00 to 6.00-inch rims. Sidewall options also differ slightly between the two sizes.

That means a restorer should resist choosing solely by appearance. The correct path is to identify the model, verify which of the two 14-inch sizes belongs on that application, and then select the sidewall style that supports the car’s desired presentation. On a judged car, the right size code is part of the authenticity story just as much as paint, trim, and wheel covers.

1958 Chevrolet tires can be suitable for highway use when they are the correct size for the model, properly mounted on the right wheel width, correctly inflated, and in sound condition. The listed 1958 Chevrolet fitments here are all bias-ply tires, and no speed ratings are shown for these products, so the sensible approach is to drive within the comfort zone of the tire, the car, and prevailing conditions. On many late-1950s Chevrolets, the vehicle’s original braking, suspension, and steering characteristics deserve as much attention as the tire itself.

For real-world use, condition matters more than appearance alone. A fresh, properly fitted bias-ply tire on a well-sorted 1958 Chevrolet is very different from an old tire on a car with neglected chassis components. Before regular highway driving, confirm the tire size, inspect for age-related deterioration, and make sure the rest of the car is prepared for sustained road speed rather than assuming the tire is the only variable.

Inflation pressure on a 1958 Chevrolet should be set with two references in mind: the vehicle manufacturer’s recommended operating pressure and the tire’s own rated pressure information. The listed load-and-pressure figures include 750-14 tires at up to 1500 to 1580 pounds at 32 psi, 800-14 tires at up to 1620 pounds at 32 psi, and 670-15 tires at up to 1450 to 1550 pounds at 32 psi depending on product. Those figures describe the tire’s load rating point, not automatically the pressure every 1958 Chevrolet should be driven at.

That distinction is important because a reproduction collector tire’s maximum rated pressure and a carmaker’s recommended service pressure are not the same thing. Use the owner’s manual, period service information, or a marque specialist to determine the car’s baseline setting, then confirm that the chosen tire’s rating supports it. Never transfer a pressure rule from one 1958 Chevrolet size to another simply because both belong to the same model year.

Before taking a 1958 Chevrolet on a longer drive, inspect each tire for cracking, cuts, bulges, uneven wear, and embedded debris, and verify cold inflation pressure. Confirm that the spare is usable and that the wheel and valve area show no obvious issues. On a collector car, it is also wise to look beyond the tires and review brakes, steering, wheel bearings, suspension, fluid levels, and lighting before relying on the car for extended road time.

Longer drives expose weaknesses that may never appear on short local outings. A 1958 Chevrolet that has spent much of its life in storage may seem fine around town yet reveal age-related rubber or chassis problems after heat builds up on the highway. Treat the tires as one part of a broader pre-trip inspection, and take extra care if the car has not been exercised regularly in recent months.
