The 1929 Windsor 85 Series comes from the late pre-war era, when American cars were transitioning into more refined, longer-wheelbase touring machines with a strong emphasis on ride quality and presence. Tire selection on a car of this age is closely tied to both appearance and correct wheel fitment, and this Windsor uses bias-ply sizing in 31X6.00 and 600-19 on 19-inch rims. That gives the owner a practical choice between period-style sizing formats rather than a modern radial conversion path. For a restoration-minded driver, the real focus is confirming which size is on the car now and matching the tire’s look and dimensions to the vehicle’s wheels and intended road use.
Which Tire Size Is Right for The 1929 Windsor 85 Series
The 1929 Windsor 85 Series uses two primary tire sizes, and both are bias-ply fitments tied to a 19-inch wheel setup. The first step is confirming which size is fitted to the car now, since pre-war vehicles are often restored, re-wheeled, or set up differently over time. Once that is established, the decision becomes choosing the proper period-style presentation and making sure the tire matches the wheel and overall vehicle setup.
31X6.00 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter and the second refers to section width in inches. On the 1929 Windsor 85 Series, it represents a traditional bias-ply fitment suited to the styling and road manners expected of a late-1920s car. This format is especially relevant to owners trying to preserve an authentic early automotive look rather than moving into later numeric sizing conventions. It is a size that should be matched carefully to the wheel already on the car and checked against existing clearances before replacement.
600-19 is a numeric bias-ply size in which the 600 indicates an approximate 6.00-inch nominal section width and the 19 identifies the rim diameter. For the 1929 Windsor 85 Series, it is a correct-era style of fitment that keeps the traditional bias-ply construction expected on a vehicle of this vintage. Available products in this size include Lester options, including a Wide Whitewall treatment in the Lester Classic Bias Ply series. This size is a strong choice for owners who want a restoration-oriented look, but wheel condition and actual installed wheel dimensions still deserve a close check.
Fitment is straightforward across the covered sub-models, with the same two bias-ply sizes associated with the Windsor 85 Series 6 Cyl. Even so, checking the exact wheel setup on the car matters because older restorations and replacement wheels can affect which of the two period sizes is currently in use.

Tire Size & Fitment
What tire size fits a 1929 Windsor 85 Series?
The 1929 Windsor 85 Series uses two primary bias-ply tire sizes: 31X6.00 and 600-19. Both sizes are associated with this vehicle, and the covered 6-cylinder sub-model uses those same period-style fitments rather than a modern radial size as a primary application.
The practical step is to confirm which size is actually on the car before ordering replacements. Pre-war cars are often restored over many decades, and wheel changes or prior replacements can leave one example wearing a different correct-era size than another. Checking the mounted tire, wheel diameter, and general wheel condition will help narrow the choice.
What size rim does a 1929 Windsor 85 Series use?
The 1929 Windsor 85 Series uses a 19-inch rim with its primary tire fitments. That 19-inch wheel diameter aligns directly with the 600-19 size, and it is the key wheel dimension to confirm before selecting a replacement tire for the car.
Older vehicles can be tricky because wheels may have been replaced, restored, or mixed over time. A tire marked for a 19-inch rim should never be chosen on size code alone without verifying the actual wheel on the car. Measuring the wheel, checking bead-seat condition, and confirming that all four wheels match can prevent an expensive mismatch.
What does 31X6.00 mean on a 1929 Windsor 85 Series?
On a 1929 Windsor 85 Series, 31X6.00 is an antique diameter-by-section size. The 31 refers to the tire’s approximate overall diameter in inches, while 6.00 refers to its section width. It is a traditional pre-war bias-ply sizing style rather than a later numeric or modern metric radial format.
That older sizing convention matters because it does not read like a modern passenger-car tire code. Owners comparing it to 600-19 should avoid assuming the two sizes are automatically interchangeable in every situation. The safer approach is to confirm the wheel setup already on the vehicle and compare the replacement tire to the car’s existing fitment.
Choosing the Right Tire
What should I consider when choosing a 600-19 tire for a 1929 Windsor 85 Series?
A 600-19 tire for a 1929 Windsor 85 Series should first match the car’s actual wheel diameter and existing fitment. From there, the main considerations are bias-ply construction, period-style appearance, and how the tire complements the vehicle’s restoration goals and intended road use.
Available 600-19 choices can differ in presentation, including sidewall treatment and tire series. A Wide Whitewall creates a more formal pre-war look, while the exact product details can also affect how the tire suits a touring car that is driven occasionally versus one built mainly for show. Wheel condition and consistency across all corners should still be part of the decision.
What sidewall styles are available for 1929 Windsor 85 Series tires?
For the 1929 Windsor 85 Series, available product choices in 600-19 include a Wide Whitewall sidewall style. On a car from this period, sidewall treatment has a major effect on the finished look because the tires are such a visible part of the vehicle’s stance and overall presentation.
Choosing a sidewall style is usually less about performance than about how the car is being finished. A wide whitewall can suit a more formal restoration-oriented appearance, while some owners may prefer a plainer look if they are matching an existing setup. Consistency across all four tires matters, especially on a pre-war car with tall, exposed sidewalls.
What tire series are available for the 1929 Windsor 85 Series?
The available 600-19 product assortment for the 1929 Windsor 85 Series includes the Lester Classic Bias Ply series. That places the tire choice squarely in the traditional bias-ply category, which is the expected construction and visual style for a vehicle of this age.
A tire series can help signal the type of appearance and overall character a buyer is selecting, even when the fitment size stays the same. On a pre-war car, that matters because the owner may be balancing judged-show presentation, weekend touring, or a long-running older restoration. The right series starts with the correct size and wheel match, then narrows by style.
Restoration & Appearance
Which tire should I choose for a period-style 1929 Windsor 85 Series?
For a period-style 1929 Windsor 85 Series, the starting point is staying with one of its primary bias-ply sizes: 31X6.00 or 600-19. Both reflect vintage sizing conventions, so the better choice depends on the wheel setup already on the car and the appearance the owner is trying to preserve.
The safest restoration path is to match the car’s existing, verified configuration rather than selecting by appearance alone. On a vehicle this old, details can vary from one long-restored example to another. If exact originality matters, period photos, marque references, and restoration documentation can help confirm whether a particular size and sidewall treatment suits the car’s history.
Does correct tire fitment matter for a 1929 Windsor 85 Series restoration?
Correct tire fitment matters a great deal on a 1929 Windsor 85 Series because tire height, width, and sidewall presentation strongly affect how the car sits and how authentic the finished restoration looks. On a pre-war vehicle, the tires are visually prominent and play a major role in the overall character.
Fitment also matters beyond appearance. A tire that does not suit the wheel or the car’s existing setup can create avoidable problems with mounting, stance, and clearance. Even when using a correct-era bias-ply size, owners should verify the actual wheel diameter, compare all four corners, and make sure the replacement matches the car’s present configuration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1929 Windsor 85 Series?
Yes, modifications can affect tire fitment on a 1929 Windsor 85 Series. Replacement wheels, earlier restoration work, suspension repairs, brake updates, or body adjustments can all change what size is currently on the car, even when the tire choice still appears period-appropriate from the outside.
That is why a pre-war car should be checked as it sits today rather than assumed to match a reference size automatically. Looking at wheel diameter, wheel width, clearance around fenders and steering components, and whether all four wheels are the same can prevent selecting a tire that suits the model in general but not the individual car.
What should I inspect before driving a 1929 Windsor 85 Series on new tires?
Before driving a 1929 Windsor 85 Series on new tires, inspect the wheels, valve hardware, and overall mounting condition, then confirm proper air pressure once the tires are installed. It also makes sense to check the steering and suspension for looseness, since a pre-war car can react noticeably to wear in those components.
A short, careful road test is a smart next step after installation. Watch for vibration, pulling, rubbing, or any sign that the tire is contacting a fender or suspension part. Older collector cars also benefit from a second pressure check after the first drive, along with a visual look at the sidewalls and beads for any settling issues.
How should tires on a collector 1929 Windsor 85 Series be maintained?
Tires on a collector 1929 Windsor 85 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires on an infrequently driven car deserve attention for sidewall cracking, cuts, bulges, flat spotting, and slow air loss, especially after long periods parked in one place.
Storage conditions matter almost as much as mileage on a car of this age. Keeping the vehicle away from prolonged sunlight, excess heat, moisture, and ozone sources can help protect the rubber over time. Even a tire that still has usable tread should be inspected closely before road use if the Windsor has spent long stretches off the road.
