The 1930 Dodge DC comes from an era when American cars were moving into smoother, more capable touring duty while still carrying distinctly prewar tire proportions and styling. For owners of a Dodge DC today, tire choice affects not just roadworthiness, but also the stance and visual character that define a late-1920s to early-1930s car. This application centers on bias-ply fitments in 28X5.50 and 550-18 on 18-inch wheels. Available choices include blackwall, wide whitewall, and double-whitewall treatments across several vintage tire series. The real decision is matching the correct size format and appearance to the car’s wheel setup, restoration direction, and intended driving use.
Which Tire Size Is Right for The 1930 Dodge DC
The 1930 Dodge DC uses two primary tire sizes, and both are bias-ply fitments tied to 18-inch wheel use. Because this fitment appears on the covered sub-model, the main task is confirming which size format matches the wheels and the tire presentation you want before comparing brands, sidewall styles, and series options.
The 28X5.50 size uses an older diameter-by-section format, where 28 refers to the tire’s approximate overall diameter and 5.50 refers to its nominal section width in inches. It is a bias-ply fitment that suits the prewar character of the 1930 Dodge DC and reflects the sizing language commonly seen on vehicles of this period. This format is especially useful for owners who want to preserve an early-style tire presentation rather than shift to a later numeric designation. Before choosing it, confirm that your current wheels and existing tire markings correspond to this antique-style format.
The 550-18 size is a numeric bias-ply designation in which 5.50 represents nominal section width in inches and 18 identifies the rim diameter. On a 1930 Dodge DC, this size opens the door to several restoration-oriented choices, including blackwall, wide whitewall, and double-whitewall styles from Excelsior, Firestone, BFGoodrich, and Michelin. Tire series also vary, including Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet. It is a strong size to evaluate when appearance, brand preference, and wheel-width compatibility all matter in the final selection.
Fitment is straightforward for the covered 1930 Dodge DC sub-model because the same two bias-ply tire sizes are associated with it. Checking the exact sub-model still matters, since it confirms that tire selection is about size format, wheel match, and appearance rather than a different trim-specific fitment.

1930 Dodge DC 8 Cyl.
The 1930 Dodge DC 8 Cyl. uses the same pair of bias-ply tire sizes associated with this model family, so there is no separate sub-model-only tire format to sort out. That lets the focus shift to confirming which size marking matches the wheels on the car and then choosing among available period-style blackwall or whitewall options.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Common 1930 Dodge DC tire questions usually center on the two size formats, 18-inch wheel fitment, bias-ply construction, sidewall appearance, and what to inspect before putting a prewar car back on the road.
Tire Size & Fitment
What tire size fits a 1930 Dodge DC?
The 1930 Dodge DC uses two primary bias-ply tire sizes: 28X5.50 and 550-18. Those two markings represent different vintage sizing formats, but both belong to this exact vehicle application and relate to the same general prewar tire profile used on 18-inch wheels.
The key is to match the size marking to the wheels and tire format already on the car. A Dodge DC that has been restored, modified, or re-wheeled over the years may not still have its original setup, so checking the wheel diameter and the existing tire designation before ordering helps avoid choosing the wrong vintage size convention.
What size rim does a 1930 Dodge DC use?
The 1930 Dodge DC uses an 18-inch rim diameter. That rim size aligns with the 550-18 numeric bias-ply fitment and supports the overall wheel sizing used for this application.
Rim diameter is the first number to confirm on a prewar car before moving into brand or sidewall choices. It also helps to verify wheel width, especially if the car has replacement wheels or long-ago restoration work, because several available 550-18 products carry different wheel-width specifications that can affect which tire is the most appropriate choice.
What does 28X5.50 mean on a 1930 Dodge DC?
On a 1930 Dodge DC, 28X5.50 is an antique diameter-by-section tire size. The 28 refers to the tire’s approximate overall diameter, while 5.50 refers to its nominal section width in inches, making it different from later numeric bias-ply sizing.
That distinction matters because a car may be wearing wheels and tires that are marked in one vintage convention while the owner is shopping in another. Reading the sidewall of the current tires, checking the wheel diameter, and comparing the car’s present stance can help determine whether the diameter-by-section marking or the 550-18 format is the better match for the setup in front of you.
Choosing the Right Tire
What should I consider when choosing a 550-18 tire for a 1930 Dodge DC?
Start with the correct size, bias-ply construction, and 18-inch wheel compatibility, then compare the details that separate one 550-18 tire from another. On the 1930 Dodge DC, available choices differ by brand, tire series, sidewall styling, wheel-width specification, and in some cases maximum load figures tied to inflation pressure.
A restoration-minded owner may focus first on whether the car looks right with a blackwall, wide whitewall, or double-whitewall presentation. A driver putting regular road miles on the car may also want to compare wheel-width requirements and the condition of the existing rims so the selected tire suits both the appearance goal and the actual wheel setup.
What sidewall styles are available for 1930 Dodge DC tires?
For the 1930 Dodge DC in 550-18, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those options give the car a very different visual impression even when the basic size and bias-ply construction remain the same.
Choosing among them depends on the look you want from the finished car. Blackwalls tend to suit a more understated touring presentation, while wide whitewall and double-whitewall tires create a more decorative prewar appearance, so it helps to compare the tire style against the car’s restoration theme, wheel finish, and overall level of historical detail.
What brands offer tires for the 1930 Dodge DC?
The 1930 Dodge DC has 550-18 tire options from Excelsior, Firestone, BFGoodrich, and Michelin. Those brands appear across several vintage-oriented tire series, including Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet.
Brand alone should not be the only deciding factor on a prewar application. It is better to compare the exact tire series, sidewall treatment, wheel-width specification, and any available load information so the final choice matches the car’s use, the look you want, and the wheel dimensions actually installed on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Dodge DC?
A period-style 1930 Dodge DC usually starts with the correct bias-ply sizing and a sidewall treatment that suits the car’s intended presentation. With 28X5.50 and 550-18 both associated with this application, the decision often comes down to matching the wheel setup first, then choosing a blackwall or whitewall look that complements the restoration.
Owners aiming for a historically sensitive result should compare current wheel measurements, surviving photos, restoration records, and marque-specific references before settling on a final appearance. That extra step is especially helpful on prewar cars, where the difference between a plain blackwall and a decorative whitewall treatment can noticeably change the car’s character.
Does correct tire fitment matter for a 1930 Dodge DC restoration?
Correct tire fitment matters a great deal on a 1930 Dodge DC because tire size and construction strongly influence stance, side profile, and overall authenticity of appearance. On a prewar car, the wrong size format or a mismatched wheel-and-tire combination can stand out immediately even to casual observers.
Fitment also affects how the car sits and how comfortably the tire works with the wheel. Getting the size and wheel relationship right before choosing a sidewall style helps prevent a restoration from looking visually off, and it reduces the chance of ending up with a tire that does not suit the car’s actual rim dimensions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Dodge DC?
Yes, modifications can affect tire fitment on a 1930 Dodge DC. Changes such as replacement wheels, altered wheel width, brake conversions, suspension work, or body repairs can all influence which of the correct vintage tire sizes makes the most sense on the finished car.
A prewar Dodge that has been updated over time should be measured rather than assumed to be stock. Checking wheel diameter, usable wheel width, steering clearance, and fender space before ordering is especially important when the car’s history includes older restorations, custom work, or substituted wheels that may differ from the original setup.
What should I inspect before driving a 1930 Dodge DC on new tires?
Before driving a 1930 Dodge DC on new tires, inspect the wheels, valve hardware, and the overall condition of the car’s steering and suspension. It also makes sense to confirm that the selected tire size matches the wheel dimensions and that the beads seat properly on sound, straight rims.
A short, careful road test is wise after installation, especially on a collector car that has spent long periods parked. Watch for uneven clearance during turning, verify inflation pressure, and keep an eye on any vibration or pull that could point to a wheel issue, alignment concern, or another chassis condition unrelated to the new tires themselves.
How should 550-18 tires on a collector 1930 Dodge DC be maintained?
550-18 tires on a collector 1930 Dodge DC should be kept properly inflated, inspected regularly, and protected from long periods of sunlight, heat, moisture, and ozone exposure. Since collector cars are often driven infrequently, sidewall condition and air retention matter just as much as visible tread wear.
Routine checks should include looking for cracking, bulges, cuts, and any signs that the tire is not sitting evenly on the rim. Occasional movement of the car, clean storage conditions, and a quick inspection before each drive help preserve the tires and reduce the chance of discovering age-related problems only after the car is already back on the road.
