1948 Chevrolet Tire Fitment Guide

1948 Chevrolet vehicles in this guide use two tire sizes: 600-16 and 670-15. Both sizes apply to the 1948 Chevrolet 6 Cyl. and the 1948 Chevrolet Wagon, and both are bias-ply constructions. The difference is wheel diameter, since 600-16 fits a 16-inch rim and 670-15 fits a 15-inch rim. Rim width ranges shown in current offerings are 4.00 to 4.50 inches for 600-16 and either 4.50 to 5.00 inches or 5.00 to 6.00 inches for 670-15, depending on the specific tire.

That means year and make alone are not enough to choose between the two sizes. A 1948 Chevrolet owner should first verify the actual wheel diameter already on the car, then compare the tire's approved rim width range with the wheel in use. Once that is confirmed, the remaining decisions usually come down to sidewall appearance and which brand best suits the character of the restoration.

On a 1948 Chevrolet tire, 600-16 is a numeric bias-ply size. The 6.00 figure is the nominal section width in inches, and the 16 identifies the rim diameter in inches. It is an older domestic sizing convention used widely before modern metric radial sizes became common. In current offerings for 1948 Chevrolet, this size appears in bias-ply construction with blackwall and wide whitewall options.

Understanding that code helps keep wheel diameter mistakes from creeping into an order. A 600-16 tire belongs on a 16-inch wheel, and several examples are built for rim widths in the 4.00 to 4.50 inch range. If your 1948 Chevrolet has already been restored or modified at some point, physically checking the wheel is smarter than assuming the size from the model name alone.

Yes and no. Both 1948 Chevrolet models covered here—the 6 Cyl. and the Wagon—share the same two tire size options, 600-16 and 670-15, so there is no model-specific split between them in this guide. Even so, those two sizes do not interchange on the same rim diameter, because one is for a 16-inch wheel and the other is for a 15-inch wheel.

That shared listing is useful because it tells you the model name does not decide the tire by itself. A buyer still needs to identify which wheels are on the car now, especially on a 1948 Chevrolet that may have seen decades of repairs, restorations, or wheel changes. Once the wheel diameter is confirmed, both models can be narrowed to the correct size quickly.

A 1948 Chevrolet owner should not choose between 600-16 and 670-15 by preference alone, because the two sizes fit different wheel diameters. The 600-16 size is built for a 16-inch rim, while the 670-15 size is built for a 15-inch rim, and both are bias-ply constructions. Since both sizes appear across the same model range, the deciding factor is the wheel actually on your car rather than whether one model is assigned one size and another model a different size.

Once wheel diameter is settled, the choice becomes more about presentation and restoration direction than about construction type. Blackwalls tend to suit a more understated utility look, while wide whitewalls create a dressier late-1940s appearance that many owners prefer on a finished show car. Checking the wheel first prevents ordering a period-correct tire that is simply the wrong diameter.

1948 Chevrolet tires are available in both blackwall and wide whitewall styles. In 600-16, examples include blackwall and wide whitewall versions from brands such as Coker Classic, Avon, BFGoodrich, and Firestone. In 670-15, the same overall sidewall choices appear through brands including Firestone, US Royal, Coker Classic, and Universal Vintage Tire. Both sizes remain within the traditional bias-ply look expected for a late-1940s Chevrolet.

Sidewall style has a strong effect on the finished personality of a 1948 Chevrolet even when fitment stays the same. Blackwalls usually lean toward a simpler working-car or fleet impression, while wide whitewalls better match the dressier visual language many restorers want for a postwar American passenger car. If show authenticity matters, compare your target look with period photos and any judging guidance from Chevrolet clubs before finalizing the style.

Several brands offer tires for 1948 Chevrolet vehicles. The 600-16 size includes BFGoodrich, Coker Classic, Avon, and Firestone among the available names, while 670-15 includes Firestone, US Royal, Coker Classic, and Universal Vintage Tire among its choices. All of the examples listed here are bias-ply products, so brand selection is more about sidewall style, series character, and approved fitment details than about choosing between bias-ply and radial construction.

That range gives a 1948 Chevrolet owner room to match the car's purpose and appearance. Some buyers prioritize a historically familiar American brand identity, while others focus on a specific whitewall treatment or a preferred tire series. Comparing the exact size, sidewall style, approved rim-width range, and load information within the brand lineup is the practical way to narrow the field.

Rim width requirements for 1948 Chevrolet tires depend on the size you are using. Current 600-16 offerings are shown for 4.00 to 4.50 inch rims. Current 670-15 offerings appear in more than one approved range, including 4.50 to 5.00 inches on some tires and 5.00 to 6.00 inches on others. That means the tire size alone is not always enough to choose the exact product within the size.

A 1948 Chevrolet owner should measure the wheel or verify its width before narrowing the product choice. Staying within the tire maker's approved rim-width range helps maintain proper section shape, tread contact, and sidewall behavior. This matters especially on older cars, where replacement wheels or restored originals may not all share the same width even when the diameter is correct.

Inner-tube status is not marked uniformly across every 1948 Chevrolet tire shown here, so it should be confirmed on the exact tire being considered and matched to the wheel construction already on the car. Both listed sizes, 600-16 and 670-15, are traditional bias-ply sizes commonly associated with vintage wheel designs, but the tire itself is only one part of the setup. Tube use can also depend on the wheel's condition, bead seat design, and whether the wheel was originally intended for tube-type service.

The practical step is to verify tube guidance before final assembly rather than assuming all 1948 Chevrolet bias-ply tires are handled the same way. If your wheel has rivets, age-related pitting, or a design typical of tube-type service, that can affect the decision as much as the tire does. A restorer familiar with late-1940s Chevrolet wheels can help confirm the safest and most appropriate setup.

A 1948 Chevrolet should be stored in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can age the sidewalls. Proper inflation matters during storage, and the car should either be moved periodically or supported in a way that reduces long static loading if it will sit for long periods. Bias-ply tires are more prone to temporary flat-spotting after extended parking than modern radials, so some stiffness on the first miles is not unusual.

Good storage habits preserve both appearance and service life on collector-car tires. If a 1948 Chevrolet sits for months at a time, regular visual checks for cracking, weathering, and pressure loss are worthwhile even when the car is not being driven. Keeping the tires clean and away from petroleum products on the garage floor also helps protect the rubber over time.

Tire life on a 1948 Chevrolet is usually judged by age and condition more than by mileage, because collector cars often cover relatively few miles. A sensible rule is to begin evaluating tires closely once they reach about five to seven years of age and to consider replacement as they approach ten years, even if the tread still looks usable. The DOT date code on the tire is the reference point for age, and sidewall cracking, hardening, or persistent air-loss issues can shorten that timeline.

That age-based approach is especially important on a car like a 1948 Chevrolet, where low annual mileage can make old tires seem newer than they are. Bias-ply tires may still look presentable long after their rubber has begun to age out. If the car is used for tours or longer road outings, replacing aged tires before they become visibly distressed is the more conservative decision.

Tires on a 1948 Chevrolet should be inspected before every drive and again before any extended outing. Check for visible cracking, cuts, bulges, irregular wear, and signs that the tire is losing pressure between drives. Because these are vintage-style bias-ply fitments, it is also wise to inspect valve stems and to pay attention to how the car feels during the first miles after storage, when flat-spotting or age-related stiffness may be most noticeable.

Frequent inspection is one of the easiest ways to prevent a small issue from becoming a roadside problem. A 1948 Chevrolet often spends more time parked than a modern daily driver, and long idle periods can hide deterioration until the next trip. If the spare tire is still part of your touring plan, include it in the same routine so it is usable when needed.

A 1948 Chevrolet 6 Cyl. would have been associated with bias-ply tire construction as original-period fitment, which aligns with the sizes and construction offered here. The two listed sizes for 1948 Chevrolet are 600-16 and 670-15, both in bias-ply form, and both also apply to the Wagon. That tells you the construction is era-correct, while the exact wheel diameter on an individual car still needs to be confirmed against the wheels on the vehicle and any model-specific factory literature you may have.

For restoration work, the safest path is to treat those sizes as the starting point and then verify the exact setup against original Chevrolet references, surviving cars, or marque-club guidance. A specific original-equipment brand should not be assumed from modern reproduction availability alone. Once the wheel diameter is confirmed, sidewall style becomes the next major authenticity choice.

Correct tire fitment matters a great deal when a 1948 Chevrolet is judged for authenticity. Size, construction type, wheel diameter match, and sidewall style all affect whether the car looks right for the period. Since 1948 Chevrolet belongs to an era when bias-ply construction was standard, an incorrect diameter or a sidewall treatment that clashes with the intended restoration theme can stand out quickly even to casual observers.

That does not mean every show follows the same standard, but it does mean tire choice should be part of the restoration plan rather than an afterthought. Owners aiming for marque judging should compare the car with period photography and check event-specific standards through Chevrolet clubs or judging manuals. Even on a driver-quality restoration, the right tire proportion and sidewall style can materially improve the car's stance.

For a 1948 Chevrolet, the difference between wide whitewall and blackwall tires is primarily visual rather than dimensional when you stay within the same listed size. Both 600-16 and 670-15 are available in blackwall and wide whitewall versions, and both remain within traditional bias-ply construction. Whitewall width can vary by product series, as seen in examples such as 3.50-inch and 3.25-inch whitewalls in 600-16 and several wide-whitewall treatments in 670-15.

That means the right choice depends on the story you want the car to tell. A blackwall often supports a simpler, more utilitarian presentation, while a wide whitewall better suits the dressed-up look many owners associate with late-1940s American cars. If authenticity is important, compare the whitewall treatment you prefer with period Chevrolet imagery and with the judging expectations of the events you plan to enter.

1948 Chevrolet tires can be suitable for highway use when they are the correct size, properly mounted, correctly inflated, and in sound condition. The sizes listed here are bias-ply, and one 600-16 offering carries an H speed rating, which corresponds to a 130 mph ceiling, while other examples in these sizes are presented without speed letters in the size line. In real use, a properly sorted 1948 Chevrolet is far more likely to be limited by its age, brakes, steering, suspension, and overall mechanical condition than by extreme speed capability.

Highway safety depends on matching the tire to the wheel, keeping pressures consistent, and respecting the driving character of a late-1940s car. Bias-ply tires do not feel like modern radials, so steering response and tracking can be more sensitive to road surface and inflation changes. A thorough pre-drive inspection matters as much as the tire choice itself when planning regular road use.

Inflation pressure for 1948 Chevrolet tires should be set with the vehicle manufacturer's recommended operating pressure in mind, while also respecting the tire maker's stated load-and-pressure limits for the exact tire size and product. Among current offerings, several 600-16 tires list 1,400 pounds at 32 psi, and 670-15 examples list capacities such as 1,450 pounds at 32 psi and 1,550 pounds at 32 psi depending on the tire. Those figures are product ratings, not a one-size-fits-all vehicle setting.

The practical approach is to start with the Chevrolet factory guidance for the car when available, then confirm that your chosen tire's rated pressure and load figures support that setup. Pressure should never be copied from one tire size to another simply because both fit 1948 Chevrolet vehicles. If the car's wheels, suspension, or use have changed over time, a knowledgeable vintage-tire specialist can help refine the final setting.

Before a longer drive in a 1948 Chevrolet, inspect each tire for sidewall cracking, cuts, bulges, punctures, and uneven wear, then confirm pressures when the tires are cold. Make sure the tires match the wheel diameter correctly, and examine valve stems and the spare before leaving. On a bias-ply-equipped car, it is also worth paying attention to any vibration or pulling that appears once the car is underway, since long storage can reveal flat spots or age-related stiffness on the road.

Tires are only one part of the pre-trip routine on a car of this age, but they are one of the easiest things to inspect thoroughly. A longer outing is also a good time to verify that the jack, spare, and wheel hardware are usable with the wheels on the car now. Combining that tire check with a broader brake, steering, and fluid inspection makes a 1948 Chevrolet much better prepared for distance driving.
