Durant 17 Series Tires

Durant 17 Series uses two listed tire sizes for 1930: 29X5.50 and 550-19. The 29X5.50 size is an antique diameter-by-section code, while 550-19 is a numeric bias-ply size that fits a 19-inch rim. Current products are available in 550-19, with a listed rim width range of 2.50 to 3.00 inches.

That means the right choice starts with the wheel already on the car, not with the model year alone. If your Durant 17 Series has 19-inch rims, 550-19 is the directly identified rim-based size; if the car is being restored around an older 29X5.50 specification, verify the wheel and original references carefully before moving forward.

On Durant 17 Series, 29X5.50 is an antique-style size code rather than a modern rim-first size. The 29 refers to the tire's overall outside diameter in inches, and the 5.50 refers to its nominal section width. That first number does not identify the wheel diameter.

This is where many restorers get tripped up, especially when comparing it to a numeric size like 550-19. If your Durant 17 Series carries a tire marked 29X5.50, inspect the wheel directly and compare it with period references before choosing a replacement, because the tire code alone does not tell you the rim diameter.

A 1930 Durant 17 Series can show two tire sizes because the model sits in a period when manufacturers and replacement listings still overlapped between older diameter-by-section sizing and newer numeric rim-based sizing. That is why 29X5.50 and 550-19 can both appear for the same year even though they are written in very different ways.

The practical takeaway is that year alone is not enough to choose a tire. Check the actual wheel diameter on your Durant 17 Series, compare the current tires if they are present, and use original manuals, restoration records, or marque expertise to determine which of the two listed sizes belongs on your specific car.

Durant 17 Series should be treated as a tube-type application for the listed sizes here. The available 550-19 products are bias-ply tires, and both the antique-style 29X5.50 and the numeric 550-19 fit the kinds of period wheel constructions that normally require tubes. A tube is required with these listed fitments.

Tube fitment matters just as much as tire size on a collector car from this era. When preparing a Durant 17 Series for road use or show use, make sure the wheel condition, flap or band arrangement where applicable, and tube compatibility are all addressed together rather than treating the tire as a standalone component.

The surest way to confirm tire size for a 1930 Durant 17 Series is to start with the wheel itself and the sizing format already fitted to the car. If the rim measures 19 inches and the existing tire uses a numeric code, 550-19 is the clear rim-based listing. If the car is built around the older 29X5.50 format, the code must be interpreted differently because it describes tire diameter and section width rather than wheel diameter.

A careful buyer will compare the wheel measurement, any surviving original paperwork, and the car's restoration history before making a final choice. That approach helps avoid ordering by appearance alone, which is especially important on Durant 17 Series because the two listed sizes belong to two different sizing conventions.

The available Durant 17 Series products in 550-19 come in two sidewall styles: blackwall and wide whitewall. Both are BFGoodrich bias-ply tires in the Silvertown Classic Bias Ply series, and both carry the same 19-inch rim diameter and load rating. The difference is visual presentation rather than basic fitment.

Choosing between them usually comes down to the look you want for the finished car and the restoration style you are following. A blackwall often suits a more restrained, workmanlike appearance, while a wide whitewall gives a more formal period look that many owners prefer on late-1920s and early-1930s American cars.

The currently listed Durant 17 Series products are from BFGoodrich. Both available tires are in size 550-19 and belong to the Silvertown Classic Bias Ply line, with one blackwall version and one 3.25-inch whitewall version. No additional brands appear in the current listed product set for this model group.

That narrower brand spread makes size verification even more important than brand comparison. Once you have confirmed that your Durant 17 Series uses the 19-inch numeric size rather than the antique-style alternative, the decision becomes more about sidewall appearance and restoration intent than about choosing among multiple manufacturers.

Durant 17 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and wide temperature swings. Long periods on cold concrete, underinflation, and concentrated vehicle weight in one spot can all shorten tire life on a low-use collector car. Clean tires and wheels before storage so grime and moisture are not left sitting against the rubber.

If the car will sit for months, move it occasionally or support it in a way that reduces flat spotting and casing stress. Owners of a Durant 17 Series also do well to maintain correct inflation, keep the wheel hardware dry and clean, and inspect tubes and rim condition whenever the tires are off the car.

Tires on a Durant 17 Series should be inspected before every drive and more thoroughly at regular intervals even if the car covers very few miles. Collector-car use tends to age tires by time, storage conditions, and inactivity as much as by tread wear. On an early-1930s bias-ply application, sidewall cracking, tread separation, tube-related air loss, and wheel condition all deserve attention.

A practical routine is to check inflation, visible cracking, bead area condition, and any change in how the car steers or rides each time the Durant 17 Series comes out. A yearly inspection by a shop familiar with vintage wheels, tube-type tires, and older suspension geometry is a wise step for a car that is driven sparingly.

Durant 17 Series tires should be replaced when age, cracking, hardening, deformation, repeated air loss, or any structural concern appears, even if the tread still looks usable. Collector tires often age out long before they wear out, particularly on lightly driven cars that spend much of their life parked. Visible tread depth alone is not a reliable measure of serviceability on a vintage bias-ply application.

Treat replacement as a condition-based decision rather than a mileage-based one. If a Durant 17 Series has been sitting for years, shows sidewall checking, rides roughly, or has uncertain service history, have the tires and tubes evaluated before further driving and replace them when condition no longer supports safe road use.

Durant 17 Series is associated here with two size references for 1930: 29X5.50 and 550-19. The currently available replacement products are BFGoodrich Silvertown Classic Bias Ply tires in 550-19, offered in blackwall and wide whitewall form. That means more than one period-style path exists within the listed fitment range, but the exact original configuration of a specific car should be matched to factory or marque sources.

For restoration work, originality is not just about mounting a tire that physically fits the wheel. A carefully judged Durant 17 Series should also reflect the right size convention, visual style, and overall presentation for the individual car, so period photos, surviving paperwork, and marque specialists remain important references.

Correct tire fitment can absolutely affect how a Durant 17 Series is judged and how seriously a restoration is taken. Size, stance, sidewall treatment, and overall period appearance all shape whether the car looks right for its year and class. On a less common independent make, those details can stand out even more to knowledgeable observers.

The best approach is to match the tire not only to the wheel but also to the restoration goal. If the Durant 17 Series is being prepared for formal judging, compare your chosen size and sidewall style against club standards, period photos, and marque guidance so the finished car reads as historically coherent rather than merely drivable.

Durant 17 Series currently has blackwall and wide whitewall choices in the available 550-19 BFGoodrich bias-ply range. Either can suit an early-1930s American restoration depending on the exact presentation of the car and the look you are trying to recreate. Sidewall style is therefore a restoration decision as much as a fitment decision.

A blackwall usually supports a simpler, more understated finish, while a wide whitewall creates a more dressed appearance that many owners associate with the period. For a Durant 17 Series being restored closely to original presentation, compare the sidewall style to period photography and surviving examples rather than choosing by preference alone.

A Durant 17 Series can be driven on public roads when the tires are the correct size, properly mounted, correctly inflated, and supported by sound wheels, tubes, brakes, steering, and suspension. The available 550-19 products are purpose-built vintage-style bias-ply tires, which is appropriate for the car's era. Safety, however, depends on the whole mechanical package, not just the tire itself.

That means road use should be approached conservatively and with realistic expectations about braking, handling, and speed compared with a modern car. Before taking a Durant 17 Series into traffic, inspect the entire chassis and running gear so the tire choice is working within a car that is equally ready for use.

Before driving a Durant 17 Series, check tire inflation, visible sidewall and tread condition, wheel security, valve stems, and any sign of tube-related air loss. It is also smart to look over steering play, brake response, wheel bearings, and suspension condition because tire performance on a vintage car depends heavily on those systems. A brief walk-around can catch problems before they become road issues.

Once underway, pay attention to pull, shimmy, unusual vibration, or a change in braking feel. A Durant 17 Series should feel consistent and predictable at modest speeds, and any sudden change in behavior is reason to stop and inspect rather than pressing on and hoping the issue clears up.

A Durant 17 Series should be driven at moderate speeds that respect the design limits of an early-1930s automobile and the behavior of bias-ply tires. Even with new vintage-style replacements, the car's steering, braking, chassis geometry, and road manners are from a different era than modern traffic. Smooth, conservative driving is the right standard.

In practice, that means treating a Durant 17 Series as a collector car rather than a high-speed cruiser. Keep speeds in a range where the car feels settled, leave extra following distance, avoid abrupt lane changes, and remember that preserving the car and its occupants matters more than trying to keep pace with faster contemporary vehicles.
