Windsor 85 Series Tires

Windsor 85 Series was part of Chrysler's late-1920s move into a more refined, upper-medium-priced American car, combining substantial coachwork with the engineering character of the prewar era. Built for 1929, Windsor 85 Series belongs to a period when tire sizing was not yet fully standardized in the way later motorists expect. Tire selection for Windsor 85 Series is not entirely straightforward because two different size conventions appear for the same model year, including an antique diameter-by-section size and a numeric bias-ply size tied to a 19-inch rim. The smartest first step is to confirm the actual wheel and rim diameter on the car before choosing a tire.

Windsor 85 Series Tire Size Guide

Windsor 85 Series uses 2 distinct tire sizes across the 1929 model year. One of those sizes uses the antique diameter-by-section format, where the leading number refers to the tire's overall outside diameter rather than the wheel diameter. That difference makes it especially important to verify the actual rim on the car before matching a modern reproduction or period-style replacement.

31X6.001929Antique diameter-by-section

31X6.00 is an antique-format size listed for 1929 Windsor 85 Series applications. The 31 indicates an overall tire diameter of about 31 inches, while 6.00 is the nominal section width in inches; the wheel diameter is not contained in the size code and must be confirmed on the actual rim. Choose this size only after verifying that the car is set up for this larger antique-style sizing convention, and because it is a bias-type format a tube is required.

600-191929Numeric bias-ply

600-19 is a numeric bias-ply size listed for 1929 Windsor 85 Series and available here with a 19-inch rim diameter. The 600 denotes a nominal 6.00-inch section width and the 19 is the wheel diameter in inches. Choose this size for Windsor 85 Series cars fitted with 19-inch wheels, especially where a period-style bias-ply look is desired, and a tube is required.

Windsor 85 Series Tires by Year

The year listing shows which tire sizes are associated with each Windsor 85 Series model year and helps narrow the search before comparing individual products. In 1929, more than two sizes are listed for Windsor 85 Series, so confirm the specific wheel and configuration on the car before selecting. The leading number in antique-style sizes is the tire's outside diameter rather than the wheel size, so the rim diameter must be checked separately.

Frequently Asked Questions

The FAQs below focus on the two different size systems used on Windsor 85 Series, how to verify the correct rim diameter, and what bias-ply collector tires require in regular ownership and restoration use.

Size Basics & Fitment

Windsor 85 Series uses two listed tire sizes for 1929: 31X6.00 and 600-19. The 600-19 size is tied to a 19-inch rim in the available product range, while 31X6.00 is an earlier-style diameter-by-section code whose wheel diameter is not stated in the size itself and has to be confirmed separately on the car.

That means the right choice depends on the actual wheels fitted to the specific Windsor 85 Series rather than the year alone. Start by reading the size on any existing tire if it is trustworthy, then measure or verify the wheel diameter and compare it with original vehicle records, restoration notes, or a Chrysler marque specialist before settling on either size.

On a Windsor 85 Series, 31X6.00 is an antique diameter-by-section size rather than a modern wheel-first size. The 31 refers to the tire's approximate overall outside diameter in inches, and the 6.00 refers to the nominal section width. It does not mean a 31-inch wheel, and the rim diameter must be identified from the actual wheel or a confirmed specification.

That distinction matters because modern buyers often read the first number as wheel diameter, which would be incorrect here. If your Windsor 85 Series carries this style of size marking, confirm the wheel itself before choosing a replacement, and plan on using an inner tube because this type of period bias-ply fitment was designed around tube-type service.

A 1929 Windsor 85 Series can show both 31X6.00 and 600-19 because two different size conventions were used for the same model year. One is an antique diameter-by-section format and the other is a numeric bias-ply format built around a 19-inch wheel diameter. They are not interchangeable by name alone, even though both appear under the same year.

The practical takeaway is that year alone is not enough to choose a tire for a Windsor 85 Series. Confirm what wheels are actually on the car, check whether it has stayed on its original specification or was changed during its life, and then match the tire to the wheel diameter and the style of fitment the car is currently using.

Windsor 85 Series fitments in this range should be treated as tube-type applications. The listed available product is a bias-ply 600-19, and both the numeric bias-ply format and the antique 31X6.00 format belong to the tube-era of collector car tire construction. A tube is therefore required for these Windsor 85 Series sizes.

Tube choice matters just as much as tire choice on an older Chrysler product like Windsor 85 Series. Use the correct tube and flap arrangement where required, make sure the wheel condition is suitable for tube service, and inspect the inside of the rim for rust, roughness, or spoke-related wear points before mounting a fresh tire.

Buying the Right Tire

The best way to confirm the correct tire size for a 1929 Windsor 85 Series is to verify the wheel diameter first and then match it to the listed size system. A car using 600-19 needs a 19-inch rim, while a car carrying 31X6.00 uses an antique format where the wheel diameter is not stated in the size marking and must be checked separately.

Begin with the wheels actually on the car, not just the model year. If the car has been restored more than once, compare the current setup with period literature, surviving tags, restoration records, and marque-club guidance so you can choose the size that matches both the hardware and the level of originality you want to preserve.

The available Windsor 85 Series product in 600-19 is offered with a wide whitewall sidewall style. That gives the car a distinctly late-1920s luxury-tourer appearance and suits many restorations aiming for a formal, period-correct presentation. No additional sidewall styles are listed in the available product range here.

Sidewall style affects the visual character of a prewar car almost as much as the wheel itself. If your Windsor 85 Series is being restored for historical accuracy, compare the sidewall treatment on the car with period photos, surviving examples, and judging standards before finalizing the tire, since whitewall width can influence the overall look of the restoration.

The available Windsor 85 Series tire listing in this range comes from Lester. The listed product is a 600-19 bias-ply tire in the Lester Classic Bias Ply series with a wide whitewall sidewall style. No other brand appears in the current product set for this model group.

For a collector-car owner, brand is only one part of the decision. The more important step is to make sure the Windsor 85 Series is matched to the correct size system and rim diameter first, then choose the product that aligns with your restoration goals, intended driving use, and the appearance you want from the finished car.

Maintenance & Longevity

A Windsor 85 Series should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large swings in temperature. Keep the tires properly inflated, avoid prolonged contact with oil or solvents, and move the car occasionally so the same section of the casing is not carrying the load for months at a time.

Long-term collector storage is easiest on the tires when the car is kept indoors and the suspension is not left to settle unevenly. If the Windsor 85 Series will sit for an extended period, many owners use wheel cradles or carefully reduce static loading, then recheck inflation and sidewall condition before the car goes back into regular show or touring use.

Tires on a Windsor 85 Series should be inspected before every drive and more thoroughly at regular intervals even if the car covers very little mileage. On a prewar collector car, that inspection should include inflation pressure, sidewall cracking, bead condition, tread separation signs, valve stem condition, and any evidence that the tube or rim is causing trouble.

Low annual mileage can hide tire problems rather than prevent them. A Windsor 85 Series often spends more time parked than driven, so age, storage conditions, and wheel condition become just as important as tread depth, and periodic hands-on inspection by someone familiar with older bias-ply and tube-type assemblies is a wise habit.

Tires on a Windsor 85 Series should be replaced when they show age cracking, hardening, deformation, cord exposure, repeated air loss, or any structural concern even if the tread still looks usable. Collector-car tires can age out long before they wear out, especially on vehicles that spend much of their life stored between events and occasional drives.

A prewar car asks more of an old tire than appearances suggest because braking, steering feel, and wheel condition are all less forgiving than on a modern car. Treat calendar age and condition as the deciding factors, and have any questionable tube-type assembly removed and inspected rather than assuming low mileage means the tire remains serviceable.

Restoration & Authenticity

Windsor 85 Series is associated here with two period-appropriate size conventions for 1929: 31X6.00 and 600-19. The available product range includes a Lester Classic Bias Ply 600-19 with a wide whitewall, which matches the general character expected of a late-1920s premium American car. That does not automatically make one choice correct for every surviving car.

Original fitment on a particular Windsor 85 Series should be verified against factory literature, surviving records, and marque-club knowledge for the exact body and wheel setup. Restorers often encounter wheel changes made decades ago, so authenticity work should begin with the car's current hardware and a careful review of period references rather than assumptions.

Correct tire fitment can absolutely affect the presentation, credibility, and judging outcome of a Windsor 85 Series restoration. Size, sidewall treatment, construction type, and overall stance all influence whether the car looks right for its period. On a car from 1929, an obviously incorrect tire profile can alter the visual balance of the entire vehicle.

That matters both for formal judged events and for private-sale confidence. If your Windsor 85 Series is being restored to a high standard, use marque clubs, period photographs, and restoration references to confirm the right combination of wheel diameter, tire size, and sidewall appearance so the finished car reflects the era it came from.

The available Windsor 85 Series product is offered with a wide whitewall, a style that fits the upscale visual language of many late-1920s American cars. Sidewall treatment was an important styling feature in the period, and a whitewall can materially change how formal or sporting the finished car appears. No alternate sidewall style is listed in the current available range here.

Correctness depends on how your specific Windsor 85 Series was equipped and how strictly you are restoring it. Use period sales material, unrestored reference cars, and judging guidance to decide whether a wide whitewall suits your car's intended presentation, especially if the goal is concours authenticity rather than a generally period-looking restoration.

Safety & Road Use

A properly selected and properly mounted collector tire can be suitable for public-road use on a Windsor 85 Series when the rest of the car is mechanically sound and the tire matches the wheel correctly. Because this is a 1929 prewar car using tube-type bias-ply-era sizing, safe use depends on condition, inflation, wheel integrity, and sympathetic driving rather than tread alone.

Road use should be approached with the expectations appropriate to a late-1920s automobile. Before regular driving, make sure the Windsor 85 Series has sound brakes, steering, wheel bearings, and rims, and treat any long-stored car as a recommissioning project rather than assuming that fresh-looking tires alone make the car ready for traffic.

Before driving a Windsor 85 Series, check tire inflation, visible sidewall condition, valve stems, wheel fasteners, and any sign of tube-related air loss or shifting on the rim. On a prewar car, it is also wise to inspect the wheels themselves for cracks, corrosion, loose hardware, or other issues that could compromise a tube-type assembly under load.

A short pre-drive inspection is especially important when the car has been sitting, even for a few weeks. Older collector cars often reveal problems only once they begin to roll, so taking a moment to check the Windsor 85 Series before each outing helps catch preventable issues while they are still garage problems rather than roadside ones.

A Windsor 85 Series should be driven at moderate, conservative speeds that respect both the design age of the car and the characteristics of bias-ply, tube-type collector tires. Even with fresh tires, a 1929 automobile does not deliver modern braking, steering response, or high-speed stability. The right pace is one that keeps the car composed and leaves a generous margin for stopping and avoidance.

In practice, that means using the Windsor 85 Series for the kind of touring, parade, and local road driving that suits a prewar car, rather than sustained fast highway travel. Smooth inputs, extra following distance, and careful route planning do more for safety than any single tire choice once the car is operating within its historical limits.
