The 1931 Jordan 6 comes from the closing years of an independent American automobile marque, giving it the kind of pre-war character that makes tire choice part of the car’s overall presentation. Cars of this era rely heavily on proper stance, wheel fitment, and sidewall appearance to look and drive as intended. The 1931 Jordan 6 uses a 650-18 bias-ply tire on an 18-inch rim, keeping the fitment squarely in traditional pre-war territory. Available choices include Firestone Balloon tires in blackwall and 3.50 inch wide whitewall form. For a roadgoing restoration, the real decision is usually how closely the tire’s look should match the vehicle’s intended finish and use.
Which Tire Size Is Right for The 1931 Jordan 6
The 1931 Jordan 6 uses one primary tire size: 650-18. That fitment is a bias-ply tire for an 18-inch rim, and the covered sub-model uses the same size, so the main decision is not the size itself but which period-style tire presentation best suits the car, along with confirming wheel width and overall condition before installation.
A 650-18 size is a vintage numeric bias-ply designation in which the 6.50 figure refers to the tire’s nominal section width in inches and the 18 identifies the wheel diameter. On a 1931 Jordan 6, that keeps the fitment aligned with the construction style expected of an early 1930s automobile. Firestone Balloon options in this size include both blackwall and wide whitewall versions, giving the owner a meaningful appearance choice without changing the basic fitment. This size is the right starting point when the goal is to preserve traditional proportions and a distinctly pre-war tire profile.
Fitment is straightforward across the covered 1931 Jordan 6 sub-model lineup. The listed sub-model uses the same 650-18 bias-ply tire size, so tire selection centers more on appearance and wheel compatibility than on trim-specific sizing differences.

1931 Jordan 6 Base
The 1931 Jordan 6 Base uses the same 650-18 bias-ply fitment as the core model. That makes the choice largely about staying with a traditional Firestone Balloon presentation and selecting the sidewall style that best matches the car’s restoration or touring character.
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 Jordan 6?
The 1931 Jordan 6 uses a 650-18 tire size. That is a bias-ply fitment on an 18-inch rim, which is consistent with the tire construction and sizing conventions used on many pre-war American automobiles.
The key step is matching the tire to the actual wheels on the car, especially if it has been apart for restoration or has had wheel changes over the years. A 650-18 should be treated as the primary fitment, but wheel width, rim condition, and overall clearance still deserve a close look before mounting new tires.
What size rim does a 1931 Jordan 6 use?
The 1931 Jordan 6 uses an 18-inch rim with its 650-18 tire size. Available tires in this size are built for that rim diameter, and the product options also show a rim-width range of 3.25 to 3.50 inches.
Rim diameter is only part of the fitment picture on a car of this age. It is also worth checking that the wheel width falls within the tire’s intended range and that the rims are sound, true, and appropriate for road use. Older wheels can look serviceable while still needing careful inspection.
Does the 1931 Jordan 6 Base use the same tire size?
Yes. The 1931 Jordan 6 Base uses the same 650-18 bias-ply tire size as the core 1931 Jordan 6 fitment. There is no separate tire-size split shown for the Base sub-model.
That simplifies the buying decision because the question is not which size fits the Base, but which version of the correct size best suits the car. Once the wheels are confirmed, the choice usually comes down to sidewall appearance, the look of a blackwall versus a wide whitewall, and the overall restoration direction.
Choosing the Right Tire
What should I consider when choosing a 650-18 tire for a 1931 Jordan 6?
Start with the correct 650-18 size and the traditional bias-ply construction used on the 1931 Jordan 6. From there, the biggest decision is usually visual: whether the car calls for a blackwall presentation or a 3.50 inch wide whitewall.
Wheel compatibility matters just as much as appearance on a pre-war car. Compare the tire’s intended rim-width range to the wheels on the vehicle, and inspect the rims closely before mounting. It also helps to think about how the Jordan will be used, since a show-focused restoration may call for a different look than a car driven regularly.
What sidewall styles are available for 1931 Jordan 6 tires?
The 1931 Jordan 6 has 650-18 tire options with both blackwall and wide whitewall sidewall treatments. In this size, the whitewall offering is a 3.50 inch wide whitewall, while another Firestone Balloon option keeps a plain blackwall look.
That choice affects the entire visual character of the car, especially on a vehicle from the early 1930s where the tire occupies a large part of the wheel opening. A blackwall gives a more understated presentation, while a wide whitewall creates a more formal period-style appearance. Either way, the tire still needs to match the correct 650-18 fitment.
How do I choose between the available 650-18 tires for a 1931 Jordan 6?
The available 650-18 tires for a 1931 Jordan 6 come from Firestone’s Balloon series, so the main differences are not a change in basic fitment but a change in presentation and specification details. Sidewall style and product weight are the clearest distinctions within the size.
A useful way to decide is to match the tire to the car’s purpose. A restoration that emphasizes traditional styling may lean toward the wide whitewall look, while a more restrained driver may suit a blackwall better. It is also smart to compare rim-width compatibility and any load information shown for the individual tire before making the final choice.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Jordan 6?
A period-style 1931 Jordan 6 should begin with the correct 650-18 bias-ply size. That preserves the car’s intended proportions and keeps the tire construction in line with what buyers expect to see on a pre-war automobile.
From there, the decision becomes one of presentation rather than fitment category. A Firestone Balloon in blackwall gives a restrained traditional look, while the 3.50 inch wide whitewall creates a more formal restoration-oriented appearance. When exact historical authenticity matters, it is worth comparing the tire choice against period photos, marque references, and surviving examples.
Does correct tire fitment matter for a 1931 Jordan 6 restoration?
Yes, correct tire fitment matters a great deal on a 1931 Jordan 6 restoration. On a car from this era, tire size, construction, and sidewall treatment all influence stance, visual balance, and the overall impression of the finished vehicle.
Using the proper 650-18 size helps keep the car from looking visually off even before it turns a wheel. The remaining choice is how the sidewall should present the car, whether blackwall or wide whitewall. A careful restoration also includes checking that the wheels themselves are appropriate in width and condition for the selected tire.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Jordan 6?
Yes. Even though the primary fitment is 650-18, modifications can affect how that tire works on a 1931 Jordan 6. Wheel replacements, altered wheel width, brake conversions, suspension work, or body changes can all influence clearance and overall compatibility.
Many pre-war cars have been updated or repaired over the decades, so it is wise to inspect the actual setup instead of assuming every car still matches original wheel specifications. Turning clearance, fender room, and wheel condition all deserve attention. That is especially important before mounting a new bias-ply tire on an older restoration.
What should I inspect before driving a 1931 Jordan 6 on new tires?
Before driving a 1931 Jordan 6 on new tires, inspect the wheels for damage, rust, cracks, and proper width, then confirm the tires are seated correctly and inflated appropriately for their intended use. The suspension, steering, and brakes should also be checked on a car of this age.
A pre-war car can have tire-related issues that are really wheel or chassis issues in disguise. It helps to verify there is no rubbing at full steering lock, no unusual lean from weak springs, and no air loss after initial installation. A short, careful shakedown drive is usually better than immediately heading out on a long trip.
How should 650-18 tires on a collector 1931 Jordan 6 be maintained?
650-18 tires on a collector 1931 Jordan 6 should be kept clean, properly inflated, and inspected regularly for cracking, cuts, bulges, and uneven wear. Cars that spend long periods parked deserve extra attention because tire aging can advance even when tread wear is minimal.
Storage conditions matter almost as much as mileage on a collector vehicle. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the rubber, and moving the car periodically can reduce stress from sitting in one position too long. Tire condition should be reviewed before every meaningful road outing, not just at seasonal intervals.
