1938 Dodge D 8 Tires

The 1938 Dodge D 8 uses two primary tire sizes: 600-16 and 650-16. Both are bias-ply tires for 16-inch wheels, but they do not apply to the same configuration. The 6 Cyl. model uses 600-16, while the 6 Cyl. (7 Passenger) model uses 650-16.

That makes sub-model identification the first step before choosing a tire. Once the correct size is confirmed, the decision shifts to sidewall style, tread character, brand, and series rather than searching for additional primary fitments. If the car has been altered over the years, it is still worth checking the actual wheel width and overall clearance before final selection.

Both primary tire sizes used on the 1938 Dodge D 8 mount on 16-inch rims. The difference between the two fitments is tire width rather than wheel diameter, so the standard 6 Cyl. and 6 Cyl. (7 Passenger) versions stay within the same 16-inch wheel family.

Knowing the rim diameter helps narrow the search quickly, but it should not be the only measurement checked. A 16-inch wheel can still vary in width, and some available tires in these sizes are intended for slightly different rim-width ranges. Confirming the actual wheel setup is especially important if the car no longer wears its original-style wheels.

The 1938 Dodge D 8 has more than one tire size because fitment changes by sub-model. The 6 Cyl. version uses 600-16, while the 6 Cyl. (7 Passenger) version uses 650-16. Both remain bias-ply tires on 16-inch rims, but the 7 Passenger configuration uses the wider size.

For a buyer, that means the extra step is not choosing between different eras of wheel design, but simply matching the tire to the correct vehicle configuration. Once that is settled, you can compare the available blackwall and whitewall options, classic passenger-car lines, and more specialty tread styles without risking a size mismatch at the starting point.

Start with the correct primary size for the specific 1938 Dodge D 8 sub-model, then confirm that the tire matches the car's 16-inch wheel setup. After size is settled, the main variables are bias-ply series, sidewall treatment, and whether the tire is aimed at passenger-car styling or a more utility-oriented tread type.

A restoration-focused car may call for a traditional blackwall or wide whitewall presentation, while a car used more practically may lead you toward a different tread pattern in the same size. Wheel width also matters, since some tires in these sizes call for different rim-width ranges. Matching the tire to both the car and the intended use usually leads to the clearest decision.

Sidewall choices for 1938 Dodge D 8 tires include blackwall and wide whitewall in both 600-16 and 650-16. In 600-16, double-whitewall options are also available. Those appearance differences can change the character of the car noticeably even when the size and basic bias-ply construction stay the same.

For a prewar Dodge, sidewall style is often one of the biggest visual decisions after confirming size. A blackwall gives a plainer, more understated presentation, while a wide whitewall creates a stronger period-style look. Because sidewall treatment does not change the need for proper size and wheel compatibility, appearance choices should come after the sub-model and rim setup are verified.

Tires for the 1938 Dodge D 8 are available from several vintage-focused brands, including BFGoodrich, Firestone, Goodyear, Coker Classic, Excelsior, Lester, Avon, STA, Garfield, Camac, Ford Script, and Tornel, depending on size and series. The selection varies between 600-16 and 650-16.

Brand alone should not be the only deciding factor. It helps more to compare each tire within the correct size by sidewall style, tire series, intended visual character, rim-width compatibility, and whether the design is a standard passenger-car bias-ply or something more specialty oriented. That approach keeps the choice tied to the actual needs of the car rather than just the name on the sidewall.

A period-style 1938 Dodge D 8 tire choice starts with the correct original-type size for the sub-model: 600-16 for the 6 Cyl. and 650-16 for the 6 Cyl. (7 Passenger). From there, a bias-ply tire in a traditional series keeps the car visually aligned with late-1930s road-car proportions and sidewall character.

The final choice usually comes down to how formal or restrained the car should look. Blackwall, wide whitewall, and some double-whitewall treatments are available depending on size, and each gives the Dodge a different presentation. If exact originality matters at a judged level, checking marque references or historical vehicle documentation is the safest way to narrow the appearance details.

On a restored 1938 Dodge D 8, tire construction shapes the car's overall stance and visual character as much as the sidewall treatment does. Because the primary fitments are bias-ply, staying with a bias-ply construction preserves the tall, upright, prewar look associated with the car's original-era wheel and tire presentation.

Appearance is not just about whitewalls versus blackwalls; the construction itself influences how authentic the finished car feels. A restoration-minded owner usually begins by keeping the proper size and traditional bias-ply format, then choosing among available series and sidewall styles. That approach keeps the Dodge visually coherent without overstating any single tire as universally correct for every restoration goal.

Yes, modifications can affect tire fitment on a 1938 Dodge D 8 even when the tire size itself is correct. Changes such as aftermarket wheels, different wheel widths, altered suspension height, brake conversions, or body and fender work can influence clearance, steering travel, and how a 600-16 or 650-16 tire sits on the car.

That is why the actual wheel and vehicle setup should be checked before choosing a tire solely by model year and name. A 16-inch rim still needs the right width, and the available tires in these sizes do not all share the same intended wheel range. Turning clearance and fender space are especially worth checking on a modified prewar chassis.

Before driving a 1938 Dodge D 8 on new tires, inspect the wheels, valve hardware, and overall mounting condition, then confirm proper inflation for the tire being used. It is also smart to look over steering and suspension components, since worn tie-rod ends, bushings, or shocks can affect how a bias-ply tire behaves on the road.

A collector car that sees limited mileage deserves an extra walk-around before regular use. Check for any contact marks inside the fenders, make sure the tires are holding air evenly, and verify that the spare matches the car's size plan. A short local drive followed by a reinspection often catches small issues before a longer trip turns them into bigger ones.

Collector-car tires on a 1938 Dodge D 8 should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of heat, sunlight, moisture, and ozone exposure. Because these are vintage-style bias-ply tires, storage conditions matter just as much as mileage does.

Low annual use can make an old tire look better than it really is, so age and condition should be taken seriously even when tread appears usable. Keeping the car clean, moving it occasionally, and checking for air loss before each outing helps prevent flat spotting and surprise failures. Any sign of deterioration deserves attention before the car goes back on the road.
