Durant 66 Series Tires

Durant 66 Series uses two listed tire sizes for 1929: 29X5.00 and 500-19. The 29X5.00 size is an antique diameter-by-section format, while 500-19 is a numeric bias-ply format. The available products tied to the listed fitments use 19-inch rims, and the 500-19 products show rim widths ranging from 4 inches to 5 inches depending on the tire.

That means the year alone is not enough to choose a tire for a Durant 66 Series. Check the wheel diameter on the car, read any surviving sidewall marking if possible, and compare the car's current setup to original-era references before deciding between the antique-format and numeric-format size.

On a Durant 66 Series, 29X5.00 is an antique-style size code. The 29 refers to the tire's approximate outside diameter in inches, and the 5.00 refers to its nominal section width. It does not mean a 29-inch wheel, because the corresponding rim diameter for the listed fitment is 19 inches.

That distinction matters because modern buyers often read the first number as wheel size when they first encounter early tire codes. If your Durant 66 Series carries this style of fitment, match both the antique size marking and the actual wheel diameter before moving ahead, and plan on using an inner tube with this type of bias-ply construction.

A 1929 Durant 66 Series can show two listed tire sizes because the same model year appears with both an antique-style size code and a numeric bias-ply size code. The sizes are 29X5.00 and 500-19, and both relate to 19-inch rims rather than two completely different wheel diameters.

That kind of split is common on late-1920s cars because tire sizing language was evolving during the period. The practical move is to inspect the wheel, compare the current tire marking if one survives, and verify which sizing convention matches your Durant 66 Series before selecting a replacement.

Durant 66 Series fitments here are bias-ply tires in antique and numeric formats, and a tube is required. That applies to both 29X5.00 and 500-19 in this model range. These are not modern tubeless radial applications, and the construction style belongs to an earlier wheel-and-tire system.

Tube fitment should be treated as part of the complete tire setup rather than an afterthought. When preparing a Durant 66 Series for road or show use, make sure the wheel condition, flap or tube arrangement, and tire size all match one another so the assembly is correct for the period and suitable for low-use collector service.

To confirm the correct tire size for a 1929 Durant 66 Series, start by checking the wheel diameter on the car and then compare any surviving tire marking to the two listed sizes: 29X5.00 and 500-19. The key detail is that 29X5.00 is not a 29-inch wheel size; it is an antique-style tire code that still corresponds to a 19-inch rim.

Once the wheel diameter is verified, compare the tire code format your car appears to have used and review whether the wheel width aligns with the listed 500-19 product range. Original manuals, period photos, and Durant specialists are especially helpful when a restoration has changed wheels or when older replacement tires used a different marking style.

The listed Durant 66 Series products in 500-19 are blackwall tires. Both available products for that size use black sidewalls, which aligns well with the practical, period-appropriate appearance many late-1920s owners want. No alternate sidewall style appears among the listed products for this model group.

For a restoration-minded owner, that means sidewall choice is straightforward within the currently listed options. The more important decision is not whitewall versus blackwall, but whether your Durant 66 Series should use the antique 29X5.00 sizing convention or the numeric 500-19 format, and whether the tire's overall look suits the intended use of the car.

The listed Durant 66 Series products come from Excelsior and Firestone. In the available 500-19 offerings, Excelsior appears with the Comp H series and Firestone appears with the Dirt Track Ribbed Front series. Those are the brands presently represented within the listed tire options for this model group.

Brand choice should come after the basic fitment questions are settled. Once you have confirmed the correct size and wheel setup for your Durant 66 Series, you can compare tread style, intended use, and period character to decide which brand and series best matches a restoration, a display car, or a more specialized driving purpose.

The listed Durant 66 Series products include two different tire series: Excelsior Comp H and Firestone Dirt Track. Both are bias-ply constructions in 500-19, but they represent different approaches in tread style and intended character. Comp H is a traditional vintage-style series name, while Dirt Track Ribbed Front points toward a more specialized front rib pattern.

For a Durant 66 Series owner, that means the choice is not only about size but also about how the car will be used and presented. A period-correct restoration may lean toward one visual style, while a special-purpose build may favor another, so compare the tread appearance and overall look to the role your car serves.

A Durant 66 Series should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, electric motors, ozone sources, and petroleum contamination. Because these are bias-ply collector-car tires, long periods of inactivity can encourage flat spotting and sidewall stress more quickly than modern daily-driver tires.

If the car will sit for extended periods, maintain proper inflation, move it occasionally, or support it in a way that reduces constant load on one contact patch. Good storage habits preserve both the tire and the driving character of a Durant 66 Series, especially when the car is used only for seasonal events and short runs.

Tires on a Durant 66 Series should be inspected before every drive and more thoroughly at regular intervals during the season. Look for cracks, sidewall distortion, tread separation, uneven wear, punctures, and any sign that the tube or casing may be shifting. On an older collector car, that quick pre-drive inspection matters more than mileage alone.

Bias-ply tires can age quietly on a car that sees very little use, so visual condition and feel are just as important as tread depth. Make it a routine to inspect the spare as well, and have a specialist examine the tires on a Durant 66 Series any time steering feel, vibration, or ride height changes unexpectedly.

Tires on a Durant 66 Series should be replaced when age, cracking, casing stiffness, impact damage, or separation makes them questionable, even if the tread still looks usable. Collector-car tires often age out before they wear out, especially on cars driven only occasionally. Visible deterioration in the sidewall or bead area is reason enough to stop using them.

That standard is especially important on a late-1920s car because the tire, tube, wheel, and chassis all work together in a much less forgiving system than a modern car. If an older tire's history is uncertain, treat replacement as preventive maintenance rather than waiting for a visible failure on the road.

Durant 66 Series is associated here with two period-correct size conventions for 1929: 29X5.00 and 500-19. The currently listed products do not establish a single original equipment brand for every car, but they do show the size range and the bias-ply construction type that belongs to the era. That makes size and construction the most reliable starting points for authenticity.

For a restoration, the best approach is to confirm which of the two size conventions matches your specific Durant 66 Series and then choose a tire that preserves the correct period appearance. Original owner material, factory literature, and Durant marque specialists are the best references when judging-level accuracy is the goal.

Correct tire fitment can absolutely affect the presentation, judging results, and perceived value of a Durant 66 Series. Judges and knowledgeable buyers notice whether the car sits properly, whether the sidewall style fits the era, and whether the tire sizing convention makes sense for the wheel and period of the restoration.

On a car like Durant 66 Series, using the right size language matters as much as the tire itself because antique and numeric sizes can look similar in width while representing a different period presentation. If authenticity matters, confirm the wheel setup and compare your choice against marque-club standards before finalizing the restoration.

The listed Durant 66 Series products available in 500-19 use blackwall sidewalls. Blackwall is a historically appropriate look for many practical late-1920s applications, and it suits the restrained, workmanlike appearance many restorers want. No alternate sidewall style appears in the listed product range for this model group.

For restoration planning, that means the greater authenticity question centers on choosing the correct size convention and overall tire character rather than selecting among several sidewall treatments. If your Durant 66 Series is being restored for formal judging, compare the car's surviving evidence and period references to make sure the blackwall presentation aligns with its intended specification.

A properly fitted, correctly mounted bias-ply tire can be suitable for limited public-road use on a Durant 66 Series when the car is mechanically sound and driven within the expectations of a 1929 automobile. Tire safety on a car of this age depends as much on wheel condition, tube setup, steering, brakes, and suspension as it does on tread itself.

The important point is to treat Durant 66 Series as a collector vehicle rather than a modern highway car. Shorter trips, conservative speeds, careful route planning, and regular inspection are part of using a late-1920s car responsibly, even when the tires are fresh and the fitment is correct.

Before driving a Durant 66 Series, check tire inflation, visible sidewall condition, tread condition, wheel security, valve stems, and any sign of tube trouble or casing shift. Also look at steering response, brake feel, and whether the car sits evenly, since a sudden change in stance can point to a tire or wheel issue.

That quick inspection is especially valuable on collector cars that may sit for long intervals between outings. A few minutes spent checking the tires and wheels on a Durant 66 Series before each drive can catch age-related problems early and helps avoid turning a simple local outing into a roadside repair.

A Durant 66 Series should be driven at conservative speeds that respect the age, chassis design, and bias-ply tire construction associated with a 1929 automobile. Even with correct replacement tires, the car's braking, steering, and suspension characteristics remain far removed from modern traffic expectations. Smooth, moderate driving is the right mindset.

In practical terms, that means using the car for the kind of touring, local events, and fair-weather driving it was suited to in period rather than sustained high-speed travel. If your Durant 66 Series has been freshly restored or has an unknown mechanical history, start with short low-speed runs and build confidence only after the whole car proves itself.
