The 1931 Jordan 66 comes from the final years of an independent American automobile maker, a period when styling, road presence, and mechanical character still depended heavily on traditional tire construction. For an owner keeping one of these uncommon cars on the road, tire choice is as much about proper stance and wheel compatibility as it is about simple replacement. The 1931 Jordan 66 uses a 6.00-18 bias-ply tire on an 18-inch rim. That keeps the decision centered on selecting the right period-style bias-ply tire rather than sorting through multiple factory fitments. For restoration-minded use, it also makes wheel condition, tube setup, and overall vehicle inspection especially important before regular driving.
Which Tire Size Is Right for The 1931 Jordan 66
The 1931 Jordan 66 uses one primary tire size: 6.00-18. It is a bias-ply fitment on an 18-inch rim, and the covered Base sub-model uses that same size, so the main decision is choosing the right style of 6.00-18 tire and confirming that the car still has the correct wheel setup before installation.
In the 6.00-18 size, the first number is the nominal section width in inches and the final number identifies the wheel diameter in inches. This is a traditional bias-ply format, which suits the era of the 1931 Jordan 66 and preserves the tire construction style commonly associated with early 1930s vehicles. Buyers looking at this size should focus on period-style presentation, wheel condition, and whether the car remains on its proper 18-inch wheels. That approach helps keep the tire choice aligned with both restoration goals and practical road use.
Tire fitment for the covered 1931 Jordan 66 sub-model is straightforward. The Base model uses the same primary tire size, so the focus shifts from identifying different fitments to choosing the right 6.00-18 bias-ply tire and confirming the wheel setup on the car.

Frequently Asked Questions
These FAQs for the 1931 Jordan 66 focus on 6.00-18 fitment, 18-inch rim compatibility, bias-ply construction, restoration-minded tire selection, and the inspections that matter before an early 1930s car returns to road use.
Tire Size & Fitment
What tire size fits a 1931 Jordan 66?
The 1931 Jordan 66 uses a 6.00-18 tire size. That is a numeric bias-ply size, and it is the primary fitment for the covered vehicle. The 1931 Jordan 66 Base uses this same 6.00-18 bias-ply size as well.
That makes the first step less about sorting between multiple factory sizes and more about confirming that the car still has the proper 18-inch wheels. On a collector car of this age, it is also smart to inspect the wheels, hardware, and overall condition of the tire and tube setup before assuming the existing configuration should simply be repeated.
What size rim does a 1931 Jordan 66 use?
The 1931 Jordan 66 uses an 18-inch rim with its 6.00-18 tire size. The rim diameter is the critical number here because the tire must match the wheel diameter exactly, and 6.00-18 is built for an 18-inch wheel.
A buyer should still verify the actual wheels on the car, especially if the vehicle has been restored, modified, or assembled from long-stored parts. Early wheels can vary in condition, and a proper fitment decision should include checking the wheel diameter, the wheel's physical condition, and whether the tire setup matches the way the car will actually be driven.
Does the 1931 Jordan 66 Base use the same tire size?
Yes. The 1931 Jordan 66 Base uses the same 6.00-18 bias-ply tire size as the covered 1931 Jordan 66 fitment. There is no separate primary tire size within the covered sub-model, so the fitment itself remains consistent.
That consistency makes the buying decision more about tire style and wheel verification than about choosing between different factory sizes. Even so, a car this old may have had wheel changes over the years, so checking the actual 18-inch rims on the vehicle is still an important step before mounting new tires or replacing an existing tube-type setup.
Choosing the Right Tire
What should I consider when choosing a 6.00-18 tire for a 1931 Jordan 66?
Start with the correct primary fitment: 6.00-18 in bias-ply construction on an 18-inch rim. For a 1931 Jordan 66, that keeps the tire choice aligned with the vehicle's era and traditional presentation, rather than moving into a modern sizing format that changes the character of the car.
After confirming size, think about how the car will be used. A restoration-oriented car may call for a more traditional look, while a vehicle intended for occasional touring still needs close attention to wheel condition, tube compatibility, and overall tire age. The right choice is the one that matches the car's wheel setup, intended use, and appearance goals.
How do I choose between the available 6.00-18 tires for a 1931 Jordan 66?
The key is to choose within the correct 6.00-18 bias-ply fitment rather than trying to solve the decision with a different primary size. On a 1931 Jordan 66, the differences that matter most are usually the tire's construction style, period-style appearance, and suitability for the wheel setup already on the car.
It helps to decide whether the goal is a more restoration-focused presentation or a general road-ready replacement that still respects the vehicle's original era. A careful buyer should also compare the tire to the wheel condition, confirm the 18-inch rim, and make sure the complete mounting setup is appropriate for a low-use collector vehicle.
What rim-fitment details matter when choosing tires for a 1931 Jordan 66?
The most important rim-fitment detail is confirming the 18-inch wheel diameter required by the 6.00-18 tire. Since the 1931 Jordan 66 uses one primary size, an incorrect wheel diameter is a much bigger issue than debating between multiple tire sizes.
Wheel condition matters just as much on a car from this era. Before fitting new tires, inspect the rims for damage, corrosion, poor repairs, or any condition that could affect mounting and air retention. It is also wise to verify that the wheels currently on the car are the ones intended for the vehicle's present setup and use.
Restoration & Appearance
Which tire should I choose for a period-style 1931 Jordan 66?
A period-style starting point for a 1931 Jordan 66 is the correct primary size: 6.00-18 in bias-ply construction. That sizing and construction match the character of an early 1930s automobile much more closely than a modern-format substitute and help preserve the car's traditional stance and visual balance.
Appearance is only part of the decision, though. A restoration-minded owner should also confirm the actual wheels on the car, the condition of the rims, and the full tire-and-tube setup before road use. When exact originality matters beyond general period style, marque-specific historical references remain the best way to refine the final choice.
Does correct tire fitment matter for a 1931 Jordan 66 restoration?
Yes, correct tire fitment matters a great deal on a 1931 Jordan 66 restoration. The 6.00-18 size and bias-ply construction influence how the car sits, how the wheels are visually filled, and how closely the finished vehicle reflects the proportions expected of a car from this period.
Using the right fitment also helps avoid practical issues that can distract from the restoration itself. An owner should confirm the 18-inch wheel size, inspect the rim condition, and make sure the vehicle has enough clearance for the tire setup actually being used. On an uncommon prewar car, those checks support both appearance and dependable road manners.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1931 Jordan 66?
Yes. Even though the primary tire size for a 1931 Jordan 66 is 6.00-18, later changes can alter what actually works on the car today. Different wheels, brake work, suspension changes, or body adjustments can all affect clearance, mounting, and the suitability of the existing tire setup.
That is especially important on an older collector vehicle that may have been restored in stages over many decades. A careful fitment check should include the actual wheel diameter, wheel condition, sidewall and fender clearance, and the steering range once the tire is mounted. Those checks matter more than assuming every surviving car remains exactly stock.
What should I inspect before driving a 1931 Jordan 66 on new tires?
Begin with the basics: confirm the 18-inch wheels, inspect the rims for damage or corrosion, and make sure the 6.00-18 tires are mounted as part of a sound overall setup. On a collector car of this age, the condition of the wheels and related components is just as important as the tires themselves.
A broader road-use inspection should also include air retention, visible cracking, cuts, bulges, tread condition, and any sign of rubbing once the car is on the ground. Since many early cars spend long periods in storage, it is wise to check the full vehicle before driving, including steering response and general mechanical readiness.
How should 6.00-18 tires on a collector 1931 Jordan 66 be maintained?
6.00-18 tires on a collector 1931 Jordan 66 should be inspected regularly even if the car is driven only occasionally. Collector vehicles often age their tires through time and storage conditions rather than mileage, so visual inspection and pressure checks matter as much as tread wear.
Good maintenance also means storing the car away from prolonged sunlight, excess heat, moisture, and ozone sources when possible. Before each driving season or a longer outing, check for cracking, flat spotting, air loss, and any wheel-related issues that could affect mounting or running condition. Low annual mileage should never be taken as proof that older tires remain road-ready.
