The 1931 Ruxton 8 Cyl. comes from one of the most distinctive corners of early American motoring, remembered for advanced engineering and dramatic styling during the Classic Era. Owners drawn to a Ruxton today are usually balancing preservation, authenticity, and careful road use rather than everyday transportation. Tire fitment for the 1931 Ruxton 8 Cyl. centers on two bias-ply sizes, 31X6.00 and 600-19, both tied to a 19-inch wheel fitment context. That keeps the decision focused on selecting the right period-style construction and appearance, including a Wide Whitewall option in 600-19. Before choosing, it is worth confirming the wheel setup on the car and deciding how closely the tire should reflect a restoration-oriented presentation.
Which Tire Size Is Right for The 1931 Ruxton 8 Cyl.
The 1931 Ruxton 8 Cyl. uses two primary tire sizes, and both are bias-ply fitments associated with the covered Base configuration. Because both sizes appear on the same vehicle line, the first step is confirming which tire size matches the wheels and overall setup on the car. Once that is established, the real choice becomes period-style presentation, construction retention, and selecting among the available product characteristics within the correct size.
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 its approximate section width in inches. On a 1931 Ruxton 8 Cyl., this is a bias-ply fitment that suits the pre-war character of the car and the way many owners approach restoration-era tire selection. The size reads differently from later numeric bias-ply sizing, so it is important not to confuse it with a modern metric radial format. This size deserves a careful wheel and fitment check before selection, especially on a vehicle that may have seen wheel changes over time.
600-19 is a numeric bias-ply size in which 600 represents an approximate 6.00-inch nominal section width and 19 identifies the rim diameter in inches. For the 1931 Ruxton 8 Cyl., it preserves the traditional bias-ply construction that collectors often want for appearance and period driving character. Available choices in this size include a Lester tire in the Lester Classic Bias Ply series with a Wide Whitewall sidewall treatment, giving the buyer an appearance decision as well as a fitment one. This size is worth evaluating closely when restoration presentation matters and the car is running the corresponding 19-inch wheel setup.
Sub-model fitment is straightforward for the covered 1931 Ruxton 8 Cyl. range because the Base model carries the same two primary bias-ply tire sizes. Checking the exact sub-model still matters because wheel changes or long-ago restoration decisions can affect which of those sizes is actually on the car today.

1931 Ruxton 8 Cyl. Base
The 1931 Ruxton 8 Cyl. Base uses the same two primary bias-ply size paths found on this vehicle line, so the key issue is confirming which wheel and tire setup the car currently carries. That makes tire selection less about trim differences and more about choosing the right period-style size and appearance for the specific car in front of you.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1931 Ruxton 8 Cyl.?
The 1931 Ruxton 8 Cyl. uses two primary tire sizes: 31X6.00 and 600-19. Both are bias-ply fitments, and the Ruxton 8 Cyl. Base is associated with both sizes rather than a single exclusive fitment path.
That means the right choice starts with confirming which wheel and tire setup is actually on the car. On an older collector vehicle, wheels may have been changed during restoration or long-term ownership, so the size on paper and the size mounted on the car are not always the same. Verifying the wheel dimensions and existing tire markings before replacing anything helps avoid ordering a period-style tire that does not match the current setup.
What size rim does a 1931 Ruxton 8 Cyl. use?
The 1931 Ruxton 8 Cyl. is tied to a 19-inch rim fitment. That rim diameter is stated directly with the 600-19 size, and the vehicle's overall fitment profile centers on 19-inch wheels.
Rim diameter is one of the most important checks on a pre-war car because tire size naming can look unfamiliar by modern standards. A 600-19 tire is built for a 19-inch rim, while 31X6.00 uses an older sizing style that should still be matched carefully to the actual wheel on the car. Measuring the wheel and checking the current tire markings is the safest way to confirm fitment before choosing a replacement.
What does 600-19 mean on a 1931 Ruxton 8 Cyl.?
On a 1931 Ruxton 8 Cyl., 600-19 is a numeric bias-ply tire size. The 600 portion refers to an approximate 6.00-inch nominal section width, and the 19 identifies the rim diameter in inches.
This older sizing system is different from modern metric radial sizing, so it helps to read the code as a vintage fitment description rather than trying to compare it directly to a modern passenger-car tire. For a Ruxton owner, that matters because replacement decisions often come down to preserving the proper pre-war look and wheel relationship, not simply finding any tire with a similar width. Confirming the wheel and existing setup keeps the choice grounded in the car itself.
Choosing the Right Tire
What should I consider when choosing a 600-19 tire for a 1931 Ruxton 8 Cyl.?
Start with the basics: the tire must match the Ruxton's actual wheel diameter and the size that belongs on the car's present setup. In 600-19, the key product characteristics are bias-ply construction, period-style presentation, and sidewall appearance, including a Wide Whitewall offering.
A pre-war car like the Ruxton usually benefits from a selection process that balances appearance and intended use. Some owners want a tire that supports a restoration-oriented look, while others are mainly preparing the car for careful touring or show-field movement. Looking at the tire series, sidewall treatment, and wheel compatibility together gives a much clearer answer than choosing by size code alone.
What sidewall styles are available for 1931 Ruxton 8 Cyl. tires?
The available 600-19 product for the 1931 Ruxton 8 Cyl. uses a Wide Whitewall sidewall style. That gives the car a strong period-style visual presence and makes sidewall appearance a meaningful part of the tire decision rather than a minor detail.
On a pre-war automobile, sidewall style changes the overall presentation as much as the tread and construction do. A whitewall can suit a restoration-oriented build or a car meant to reflect the formal visual language of the era. Even so, appearance should be considered only after the correct size and wheel fitment are confirmed, since a visually appealing tire still needs to match the Ruxton's actual setup.
What brands offer tires for the 1931 Ruxton 8 Cyl.?
The available product coverage for the 1931 Ruxton 8 Cyl. includes Lester in the 600-19 size. That tire is part of the Lester Classic Bias Ply series and carries a Wide Whitewall sidewall treatment.
Brand matters mainly as part of the overall product character rather than as a shortcut to the right answer. On a specialty vehicle like a Ruxton, the more important questions are whether the tire matches the correct vintage size, whether the construction remains bias-ply, and whether the sidewall style suits the way the car is being presented. Looking at those factors together makes brand comparison more useful.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Ruxton 8 Cyl.?
A period-style 1931 Ruxton 8 Cyl. should stay focused on the correct primary bias-ply size for the car's actual wheel setup, whether that is 31X6.00 or 600-19. Keeping the vintage construction is usually central to maintaining the visual and mechanical character expected on a pre-war automobile.
Once the correct size is confirmed, appearance choices become more meaningful. In 600-19, a Wide Whitewall presentation is available and may suit a restoration-oriented look, but exact originality should be checked against marque-specific historical references if that level of detail matters. The best starting point is matching the correct size and wheel relationship first, then refining the sidewall style to fit the car's restoration goals.
Does correct tire fitment matter for a 1931 Ruxton 8 Cyl. restoration?
Correct tire fitment matters a great deal on a 1931 Ruxton 8 Cyl. because tire size, construction, and sidewall presentation all shape the car's stance and visual balance. On a pre-war luxury automobile, the tires are a large and highly visible part of the finished restoration.
Fitment also affects practicality, since an incorrect size can create problems with wheel compatibility or simply look out of place on such a distinctive car. Even when the goal is mostly aesthetic, it still pays to confirm the mounted wheels, current tire markings, and overall setup before ordering replacements. That approach helps the car retain a coherent period-style appearance without guessing at what belongs on it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Ruxton 8 Cyl.?
Yes. Any 1931 Ruxton 8 Cyl. that has had wheel changes, suspension work, or body-related alterations can require closer fitment review before replacing tires. That is especially important here because the Ruxton is associated with two different primary bias-ply sizes rather than one simple modern equivalent.
Cars of this age often pass through multiple restorations, and small changes made decades ago can influence what fits today. A different wheel diameter, altered wheel width, or changes in ride height can all affect clearance and tire choice. Looking at the current wheel setup on the car, not just the model name, is the practical way to avoid mismatching an antique-size tire to a modified chassis.
What should I inspect before driving a 1931 Ruxton 8 Cyl. on new tires?
Before road use, inspect the wheels, valve stems, mounting condition, and tire pressure, and make sure the new tires match the Ruxton's actual wheel diameter and installed fitment. It is also wise to look over the suspension and steering for looseness that could affect how a pre-war car tracks on fresh bias-ply tires.
A short shakedown drive should be treated as a systems check rather than a routine trip. Watch for rubbing at full steering lock, uneven stance, vibration, or signs that the tires are not seated or centered properly. Collector vehicles that spend long periods parked can reveal issues only once they move again, so checking the car carefully after installation is just as important as selecting the correct tire size.
How should 600-19 tires on a collector 1931 Ruxton 8 Cyl. be maintained?
600-19 tires on a collector 1931 Ruxton 8 Cyl. should be maintained with regular pressure checks, routine visual inspection, and protection from long-term heat, sunlight, and ozone exposure. Bias-ply tires on low-use cars also deserve periodic checks for cracking, cuts, bulges, and any signs of air loss between drives.
Storage conditions matter because a collector car often spends far more time parked than driven. Keeping the Ruxton in a clean, dry environment and inspecting the tires before each outing helps catch age-related issues early. Even a tire that looks good from a distance can develop condition problems over time, so close inspection is part of responsible road use on a pre-war automobile.
