The 1929 Durant 4-40 comes from a period when independent American automakers were competing hard on style, value, and everyday usability just before the market changed dramatically. Owners of these late-1920s cars usually balance preservation, correct visual character, and careful road manners more than outright speed or modernized handling. Tire fitment on the 1929 Durant 4-40 centers on bias-ply sizing, with 28X4.75 and 475-19 both tied to this model. That makes the real decision less about modern conversion and more about understanding which wheel setup is on the car and whether a blackwall or wide whitewall presentation better suits the restoration.
Which Tire Size Is Right for The 1929 Durant 4-40
The 1929 Durant 4-40 uses two primary tire sizes, and the first step is confirming which wheel setup is actually on the car. Both fitments are bias-ply, but they do not share the same rim diameter, so selecting the right tire begins with checking whether the vehicle is equipped for the 28X4.75 or the 475-19 size before comparing appearance and product choices.
The 28X4.75 size uses an older diameter-by-section system, where 28 refers to approximate overall tire diameter and 4.75 refers to nominal section width. It is a bias-ply fitment suited to the pre-war style and wheel conventions associated with a car like the 1929 Durant 4-40. This format is quite different from later numeric bias-ply sizing, so it needs to be read carefully rather than matched by appearance alone. Choosing this size starts with confirming the actual wheel diameter on the car and making sure the mounted wheel and tire setup matches this older sizing method.
The 475-19 size is a numeric bias-ply designation in which 4.75 represents the nominal tire width and 19 identifies the rim diameter. On the 1929 Durant 4-40, this keeps the period-correct construction style while using a format that is familiar across many late-1920s and early-1930s applications. Available choices in this size include Goodyear Deluxe All-Weather tires in both blackwall and wide whitewall form, giving the owner a traditional visual decision within the same fitment. This size is worth considering when the car is on 19-inch wheels and the goal is a restoration-oriented presentation.
Sub-model fitment is straightforward here because the covered 1929 Durant 4-40 sub-model uses the same two bias-ply tire sizes. The important step is not comparing trims, but confirming which wheel and tire setup is installed on the individual car before selecting replacements.

These 1929 Durant 4-40 tire FAQs focus on the difference between 28X4.75 and 475-19 fitment, 19-inch wheel confirmation, bias-ply tire selection, restoration-oriented appearance choices, and the basic inspections that matter before road use.
Tire Size & Fitment
What tire size fits a 1929 Durant 4-40?
The 1929 Durant 4-40 is associated with two primary tire sizes: 28X4.75 and 475-19. Both are bias-ply fitments, but they are not the same format and they do not use the same rim diameter, so they should not be treated as interchangeable simply because the section width appears similar.
The practical step is to inspect the wheels already on the car and confirm which setup it actually uses. Many surviving cars have been restored, repaired, or reassembled over time, so the right replacement starts with the wheel in front of you rather than assumptions based only on the model name.
What size rim does a 1929 Durant 4-40 use?
Rim size depends on which tire size is on the 1929 Durant 4-40. The 475-19 tire uses a 19-inch rim, while the 28X4.75 fitment is associated with a different wheel setup and should be verified carefully before ordering tires or tubes.
Wheel diameter is the key measurement to confirm because a mismatch here stops the project immediately. Check the wheel itself, not just an old sidewall marking, and also make sure the wheel width and overall condition are suitable for continued use on a collector car that may have sat for long periods.
What does 475-19 mean on a 1929 Durant 4-40?
On a 1929 Durant 4-40, 475-19 is a vintage numeric bias-ply size. The 4.75 portion refers to nominal section width in inches, and the 19 identifies the rim diameter, making it a traditional pre-war tire designation rather than a modern metric or radial size format.
Understanding that code helps separate wheel fitment from appearance choices. Once the car is confirmed to use 19-inch wheels, the next decisions are usually whether the restoration calls for a blackwall or wide whitewall look and whether the existing wheels are appropriate for continued service.
Choosing the Right Tire
What should I consider when choosing a 475-19 tire for a 1929 Durant 4-40?
Start with the correct fitment, which means confirming that the car actually uses the 475-19 size and a 19-inch rim. From there, the main choices center on traditional bias-ply construction, the Goodyear Deluxe All-Weather series, and whether a blackwall or wide whitewall presentation better suits the car.
It also helps to compare details such as rim-width compatibility, load capacity, and the condition of the wheels themselves. A pre-war car may look complete yet still have mismatched parts from earlier work, so careful checking matters as much as the visual style of the replacement tire.
What sidewall styles are available for 1929 Durant 4-40 tires?
For the 475-19 fitment used on the 1929 Durant 4-40, available sidewall styles include blackwall and wide whitewall. Both choices stay within the same Goodyear Deluxe All-Weather bias-ply series, so the difference is primarily visual rather than a change in the underlying size or construction.
That makes sidewall choice an appearance decision tied to the car's restoration character. A blackwall usually gives a more restrained period look, while a wide whitewall creates a more formal, show-oriented presentation, and the right pick depends on how the vehicle is being finished and displayed.
How do I choose between the available 475-19 tires for a 1929 Durant 4-40?
The available 475-19 choices for a 1929 Durant 4-40 are closely related because they share the same Goodyear brand, Deluxe All-Weather series, bias-ply construction, load figure, and rim-width specification. The meaningful difference is the sidewall treatment: one is a blackwall and the other uses a 2.875-inch wide whitewall.
Selection usually comes down to how the car is being restored and presented. A driver-focused car may lean toward the cleaner blackwall look, while a more formal restoration may call for the whitewall, provided the wheel condition, mounted clearances, and overall visual theme of the car support that choice.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Durant 4-40?
A period-style 1929 Durant 4-40 begins with staying in the correct bias-ply fitment that matches the wheel setup on the car, whether that is 28X4.75 or 475-19. For cars using 475-19, the Goodyear Deluxe All-Weather line offers a traditional pre-war tread and sidewall presentation appropriate to the era.
The right choice depends on how closely the restoration is following a known historical presentation. If exact originality matters, compare the tire style against marque references, photos, or surviving documentation, then confirm that the wheel diameter and overall setup on the car still match the intended fitment.
Does correct tire fitment matter for a 1929 Durant 4-40 restoration?
Correct tire fitment matters a great deal on a 1929 Durant 4-40 because the tire strongly affects stance, wheel appearance, and the overall visual balance of a pre-war car. Using the right size format and the correct bias-ply construction keeps the restoration closer to the period character these cars are known for.
Fitment is not just cosmetic, either. The wrong rim diameter or an incorrect tire profile can create mounting problems, awkward proportions, and clearance issues that distract from otherwise careful restoration work, so wheel verification should happen before focusing on sidewall style or other finishing details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Durant 4-40?
Yes, modifications can affect tire fitment on a 1929 Durant 4-40, especially on a vehicle that may have had wheel changes, brake work, suspension repairs, or non-original rims installed over many decades. Even when the car still looks stock, those changes can alter which tire size and wheel diameter actually belong on it now.
That is why wheel inspection comes before tire ordering on a car of this age. Check the diameter, width, and overall wheel condition, then look for clearance at the fenders and steering components so the replacement tire matches the real setup instead of an assumed one.
What should I inspect before driving a 1929 Durant 4-40 on new tires?
Before driving a 1929 Durant 4-40 on new tires, inspect the wheels for rust, cracks, bent areas, and secure mounting surfaces. The tires themselves should be checked for proper inflation, bead seating, visible damage, and even positioning on the rim, especially on a collector car returning to use after long storage.
A short, cautious initial drive is a smart next step because it gives time to feel for vibration, rubbing, or steering irregularities. It also helps to recheck inflation and hardware afterward, since an older car can reveal wheel, hub, or suspension issues only once it is moving under load.
How should 475-19 tires on a collector 1929 Durant 4-40 be maintained?
475-19 tires on a collector 1929 Durant 4-40 should be maintained with regular pressure checks, visual inspection for cracking or cuts, and close attention to any air loss while the car is stored. Collector vehicles often accumulate little mileage, so age and storage conditions matter just as much as tread wear.
Good storage habits help preserve both appearance and service life. Keep the car away from prolonged sunlight, moisture, and ozone sources when possible, and inspect the tires before each outing so sidewall condition, wheel integrity, and general readiness are reviewed before the car returns to the road.
