1950 Chevrolet 6 Cyl. Tires

The primary tire size for the 1950 Chevrolet 6 Cyl. is 670-15. That is a vintage numeric bias-ply size used on a 15-inch rim, and it is the main fitment point for selecting a period-style replacement tire for this Chevrolet application.

Using the correct size is only the first step. After confirming 670-15, the next decision is whether to stay with a bias-ply tire or consider one of the radial equivalents, then choose among blackwall, narrow whitewall, or wide whitewall styles based on the car’s appearance goals and wheel setup.

The 1950 Chevrolet 6 Cyl. tire fitment centers on a 15-inch rim diameter. That matches the 670-15 primary tire size and also provides the wheel diameter reference point when comparing available radial-equivalent sizes such as 195R15, P205/75R15, P215/70R15, and 670R15.

Rim diameter alone does not settle the whole fitment question. Wheel width should also be checked, especially if the car has replacement wheels or if a radial alternative is being considered, because construction type, sidewall shape, and clearance can all change how the tire works on the vehicle.

The 670-15 size is a numeric bias-ply format. In plain terms, 6.70 refers to the tire’s nominal section width in inches, while 15 identifies the rim diameter, so the size describes a traditional bias-ply tire built for a 15-inch wheel.

That older sizing format matters because it points you toward tires that look and behave like vintage fitments rather than modern low-profile designs. Once 670-15 is confirmed, the practical choice becomes sidewall style, brand, and tire series, plus whether a radial equivalent makes sense for the car’s current wheel and road-use setup.

For the 1950 Chevrolet 6 Cyl., 670-15 is the primary bias-ply tire size. The available product selection in that size is centered on bias-ply construction, which suits owners who want a traditional vintage tire format and period-style appearance.

That matters because staying with bias-ply keeps the car in its original style of construction, while moving to a radial means shifting to an equivalent rather than the primary fitment. A change in construction should be checked against wheel width, tire dimensions, and fender or steering clearance before the car goes back into regular road use.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those represent an 80-series metric radial, a 75-series P-metric radial, a 70-series P-metric radial, and a bias-look radial alternative that keeps a more traditional visual character.

Each of those sizes gives a different route away from the original bias-ply format, so the comparison should go beyond rim diameter alone. The recommended rim-width range for these equivalents is 5 to 7 inches, and overall wheel compatibility, section width, and body or suspension clearance should be verified before making the change.

A 670R15 bias-look radial is available as a radial equivalent for the 1950 Chevrolet 6 Cyl. It is intended for owners who want a radial construction while keeping a tire size and visual presentation that stays closer to the car’s traditional bias-ply look.

That makes it a useful middle ground for some cars, but it still needs to be treated as an equivalent rather than an automatic substitute. Wheel width, overall dimensions, and clearance around the fenders and steering components should be checked carefully, especially if the Chevrolet has been altered from its original wheel or suspension setup.

Start with the correct 670-15 size and the fact that it is a bias-ply fitment on a 15-inch rim. From there, the main decisions are sidewall appearance, tire series, brand, rim-width compatibility, and whether the car is being equipped for a restoration-minded look or broader road use.

A blackwall gives a plainer, more utilitarian presentation, while narrow and wide whitewalls change the car’s visual character significantly. It also helps to compare the wheel width on the car to the tire’s rim-width specification and to confirm that load capacity and overall tire style match how the Chevrolet will actually be driven.

The 1950 Chevrolet 6 Cyl. has 670-15 tire options in blackwall, narrow whitewall, and wide whitewall styles. That gives owners room to tailor the appearance from a simpler postwar look to a brighter restoration-oriented presentation without changing the primary size.

Sidewall choice has a strong visual effect on a 1950 Chevrolet, especially because whitewall width changes the car’s stance and period impression. The safest approach is to choose the style that matches the vehicle’s build goal, then confirm the tire’s construction and rim-width compatibility rather than selecting by appearance alone.

The 670-15 size for the 1950 Chevrolet 6 Cyl. is available from Firestone, US Royal, Coker Classic, Universal Vintage Tire, BFGoodrich, Excelsior, Avon, Goodyear, and STA. Those brands appear across several classic bias-ply series and sidewall treatments in the correct primary size.

Brand choice should be used to narrow the look and specification that best suits the car, not as a shortcut around fitment. Comparing tire series, sidewall style, load information where shown, and rim-width guidance will tell you more than the brand name alone when deciding which 670-15 tire belongs on your Chevrolet.

A period-style starting point for a 1950 Chevrolet 6 Cyl. is the original-format 670-15 bias-ply tire. Staying with that primary size preserves the vintage numeric sizing system and opens the door to traditional blackwall, narrow whitewall, or wide whitewall choices depending on the look being built.

For many restorations, the real question is not the size but the presentation. Owners seeking the most historically precise appearance should compare the tire’s sidewall treatment with factory literature, marque references, or period photographs, while owners building a driver can focus on the 670-15 style that best suits the car’s finished character.

Tire construction changes both the look and feel of a restored 1950 Chevrolet 6 Cyl. A 670-15 bias-ply keeps the car in a traditional vintage format, while a radial equivalent can shift the visual impression even when the rim diameter remains the same.

That difference is especially important on a postwar sedan where tire profile and sidewall presentation contribute to the overall stance. Owners who want a more traditional appearance often stay with bias-ply or consider a bias-look radial, while any move to a modern radial format should still be checked against wheel fit and body clearance.

Modifications can absolutely affect tire fitment on a 1950 Chevrolet 6 Cyl. Even though 670-15 is the primary size, aftermarket wheels, suspension changes, altered ride height, brake updates, or bodywork can change the space available around the tire and the wheel dimensions it needs.

That becomes even more important when comparing radial equivalents, because the wheel may no longer match the original-style tire assumptions. A modified Chevrolet should be checked for actual rim width, steering clearance, and fender room before tires are chosen, rather than relying only on the original size associated with the car.

Before driving a 1950 Chevrolet 6 Cyl. on new tires, inspect the wheels for correct diameter and sound condition, then check that the tires are mounted in the proper size and construction. It also makes sense to confirm air pressure, look over valve stems, and make sure there is no interference at full steering lock.

A collector car that has been parked for long periods deserves a broader once-over. Suspension wear, loose steering parts, uneven wheel alignment, and brake issues can all affect how fresh tires behave, so a careful inspection of the car’s basic running condition is just as important as the tires themselves.

670-15 tires on a collector 1950 Chevrolet 6 Cyl. should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and air loss, and checked for tread wear even if the car sees only occasional use. Low annual mileage does not prevent aging, especially on older collector vehicles.

Storage conditions matter as much as road miles. Keeping the Chevrolet away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires, while periodic movement of the car reduces long stationary loading. Any tire showing age-related deterioration should be evaluated before the car is taken on longer drives.
