1950 Chevrolet Wagon Tires

The 1950 Chevrolet Wagon uses a 670-15 tire size. That is a numeric bias-ply size mounted on a 15-inch rim, and it is the primary fitment for the covered vehicle. The Base sub-model uses this same size, so there is not a second primary tire size to sort through first.

Once the size is confirmed, the choice shifts to tire style and construction path rather than alternate fitments. Many 670-15 options differ by blackwall, narrow whitewall, or wide whitewall appearance, and radial equivalents are also available for buyers considering a change from the original bias-ply format. Wheel width and clearance should still be verified on any wagon that has been modified.

The 1950 Chevrolet Wagon uses a 15-inch rim with its 670-15 tire size. The tire size itself ends in 15, and the primary fitment is built around that wheel diameter. For this vehicle, getting the rim diameter right is simple because there is only one primary tire size to match.

Rim diameter is only one part of the fitment picture, especially on an older wagon that may have seen wheel changes over the years. It also helps to confirm actual wheel width before selecting among available 670-15 tires or moving to a radial equivalent, since product rim-width specifications and equivalent rim-width guidance can differ from one option to another.

A 670-15 is a vintage numeric bias-ply size. The 6.70 portion refers to the tire’s nominal section width in inches, while the 15 identifies the wheel diameter in inches. This older sizing system is different from modern metric radial sizes, so it often looks unfamiliar even though it is correct for many postwar American vehicles.

Understanding the format helps when comparing period-style tires to radial alternatives. A 670-15 is not just a width and diameter label; it also points to the bias-ply construction style the wagon was fitted around. That is why a buyer should compare construction type, sidewall treatment, and wheel compatibility carefully rather than assuming a modern-looking size automatically serves the same role.

For the 1950 Chevrolet Wagon, 670-15 is a bias-ply primary fitment. That construction is part of the vehicle’s original tire sizing convention and shapes the traditional appearance associated with an early postwar Chevrolet wagon. The available products in this primary size are bias-ply tires rather than modern radials in the same exact sizing format.

That distinction matters because a radial-equivalent option is a separate decision from choosing a 670-15 bias-ply tire. Buyers trying to keep a more period-style look often stay with bias-ply construction, while others may compare radial equivalents for road use. Either way, the wheel diameter is still 15 inches, and wheel width plus vehicle clearance should be checked before any construction change.

Radial equivalents for 670-15 include 195R15, P205/75R15, P215/70R15, and 670R15. Those cover an 80-series metric radial, a 75-series P-metric radial, a lower-profile 70-series P-metric radial, and a bias-look radial equivalent. Each one offers a different sizing convention while serving as a comparison point to the original 670-15 bias-ply fitment.

The practical difference is not just the numbers on the sidewall but the way each equivalent relates to wheel width and overall fitment. A 5-7 inch rim-width range is associated with these radial equivalents, so the wagon’s actual wheels should be measured before conversion. Clearance around fenders and steering components also deserves a careful check rather than assuming any equivalent is automatically interchangeable.

A 670R15 bias-look radial is available as a radial equivalent for the 1950 Chevrolet Wagon’s original 670-15 size. That makes it a useful option for owners who want a radial construction while keeping a tire presentation that feels closer to the wagon’s vintage character than a purely modern metric sidewall format.

A bias-look radial should still be treated as an alternative, not as an automatic one-for-one swap. The wheel needs to be compatible, and the wagon should be checked for width and clearance before converting from the original bias-ply setup. It is also worth deciding whether the project priority is traditional restoration appearance, regular driving use, or a balance between the two.

Start with the confirmed primary size, 670-15, and the 15-inch wheel diameter. From there, the main choices are construction style, sidewall appearance, brand, tire series, and rim-width compatibility. Because this wagon uses one established vintage size, selecting the right tire is more about matching the vehicle’s intended look and use than sorting between multiple primary fitments.

A restoration-oriented wagon may call for a whitewall treatment that suits the era, while a more utilitarian presentation may lean toward blackwall. It also helps to compare product details such as rim-width specification and load figures where they are stated. Those differences can matter if the vehicle has replacement wheels, added cargo use, or a driving pattern that goes beyond occasional show and cruise duty.

The 1950 Chevrolet Wagon’s 670-15 tire options include blackwall, narrow whitewall, and wide whitewall styles. That gives buyers a broad spread of visual choices within the same vintage size, from a more understated utility look to the fuller whitewall presentation often associated with early 1950s American cars and wagons.

Sidewall style changes the wagon’s appearance immediately, even when the tire size stays the same. A wide whitewall tends to emphasize a more formal, restoration-oriented look, while blackwall keeps things simpler and more workmanlike. The best choice depends on how the wagon is being presented, and it helps to compare whitewall widths across the available products rather than choosing by brand name alone.

Tires for the 1950 Chevrolet Wagon in 670-15 are available from Firestone, BFGoodrich, US Royal, Goodyear, Universal Vintage Tire, Coker Classic, Excelsior, STA, and Avon. Those brands appear across several bias-ply series, with differences in sidewall treatment, rim-width specification, and in some cases load figures and tire weight.

The most useful way to compare brands here is by how closely a given tire matches the wagon’s goals. Some choices emphasize traditional blackwall or whitewall presentation, while others may suit heavier-duty use or a more specialized vintage style. Looking at brand together with tire series and sidewall style gives a clearer picture than treating brand name alone as the deciding factor.

A period-style 1950 Chevrolet Wagon usually starts with the original 670-15 bias-ply size on a 15-inch rim. Within that fitment, the most important appearance choices are blackwall, narrow whitewall, or wide whitewall, along with the tire series and brand presentation that best suit the wagon’s restoration direction.

The right answer depends on whether the goal is a clean driver, a restoration-oriented show vehicle, or a practical long-roof with a traditional stance. Bias-ply construction keeps the sizing and look closest to the wagon’s era. When exact originality matters, marque-specific references, period photography, and build documentation are the better guides for choosing a particular sidewall treatment or brand style.

Tire construction changes more than road feel on a restored 1950 Chevrolet Wagon; it also changes the visual language of the vehicle. The original 670-15 fitment is bias-ply, and that construction is part of the wagon’s traditional stance and vintage presentation. A radial alternative can shift the look even when it stays close in overall intent.

That is why many restoration-minded owners begin with a bias-ply tire and then choose sidewall styling to complete the appearance. A bias-look radial can be considered when a more traditional look is still important, but it should not be treated as visually identical by default. The wheel setup and the finished profile of the tire on the vehicle both deserve a careful look before deciding.

Yes, modifications can affect tire fitment on a 1950 Chevrolet Wagon even when the intended tire size remains 670-15. Aftermarket wheels, changed wheel widths, suspension alterations, lowering, or bodywork repairs can all influence how a tire sits in the wheel opening and how much room it has during steering and suspension movement.

That is especially important when moving from the original bias-ply fitment to a radial equivalent, since wheel-width needs may change. A wagon that still appears stock can still have replacement wheels installed over the years, so measuring the actual rim and checking clearance at full steering lock is a smart step. Tire selection should follow the vehicle’s present setup, not assumptions about its past.

Before driving a 1950 Chevrolet Wagon on new tires, inspect the wheels for correct diameter and condition, confirm lug hardware and mounting surfaces, and make sure the tires are inflated properly for the chosen application. It also helps to look over the steering and suspension for looseness, since worn components can mask or exaggerate how new tires behave.

A short initial check should include tread-to-fender clearance, sidewall clearance near suspension parts, and any sign of rubbing during turns. On a collector wagon that has been parked for long stretches, it is also wise to inspect old valve stems, look for fluid leaks that could reach the tires, and verify that the spare and jack setup are still usable before longer road use.

Collector-car 670-15 tires should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is low, a 1950 Chevrolet Wagon that sees limited use can still develop age-related concerns such as sidewall cracking, flat spotting, air loss, or weathering from heat, sunlight, and long periods of inactivity.

Good maintenance means checking the tires before each outing rather than assuming low mileage equals good condition. Keep the wagon stored away from prolonged sun and ozone sources when possible, and look for bulges, cuts, or uneven wear that may point to alignment or suspension issues. Periodic wheel inspection matters too, since an older rim can create problems that look like tire trouble.
