The 1930 Jordan 80 Standard comes from the final years of an independent American automaker known for building stylish cars with a distinctive personality. For owners restoring or maintaining one today, tire choice is part of preserving that late pre-war character while keeping the car usable and properly supported on the road. This Jordan 80 Standard uses bias-ply fitments in two period-size formats, 30X6.00 and 6.00-18, both tied to the same 18-inch wheel diameter. That leaves room to compare sizing notation as much as tire style. The right decision starts with confirming the wheel and selecting the size presentation that best suits the car's restoration goals and road use.
Which Tire Size Is Right for The 1930 Jordan 80 Standard
The 1930 Jordan 80 Standard uses two primary tire sizes, and both apply to the Base sub-model. Because both fitments are bias-ply and relate to an 18-inch wheel setup, the real task is confirming which size notation matches the wheels and the presentation you want before choosing among available tires.
30X6.00 is an antique diameter-by-section size, meaning the first number refers to the tire's approximate overall diameter and the second number refers to its section width in inches. On the 1930 Jordan 80 Standard, it represents a period bias-ply fitment suited to pre-war tire sizing conventions. This format tends to appeal to owners who want a very early style of tire designation rather than a later numeric bias-ply marking. It is worth comparing the actual wheel and current tire markings on the car so the replacement matches both the rim setup and the look you want to preserve.
6.00-18 is a numeric bias-ply size in which 6.00 indicates the nominal section width in inches and 18 identifies the wheel diameter. For the 1930 Jordan 80 Standard, this is another correct-era bias-ply fitment and it works within the same general vintage tire vocabulary buyers expect on a pre-war automobile. Numeric sizing is often easier for owners to recognize when comparing existing wheel and tire markings. Choosing this size starts with confirming that the car's wheel setup corresponds to the 18-inch application and that the tire's proportions suit the vehicle's restoration or touring plans.
Sub-model fitment is straightforward here because the covered 1930 Jordan 80 Standard Base uses the same two bias-ply sizes. Checking the sub-model still matters, but the main decision is confirming which of the two period size formats belongs on the wheels currently on the car.

1930 Jordan 80 Standard Base
The 1930 Jordan 80 Standard Base uses both 30X6.00 and 6.00-18 bias-ply fitments. That makes tire selection less about trim differences and more about verifying the wheel setup, the size marking already on the car, and the period-style appearance you want to maintain.
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.
Frequently Asked Questions
These FAQs focus on the two bias-ply tire sizes used on the 1930 Jordan 80 Standard, how to interpret those vintage markings, and what to check for fitment, restoration appearance, and safe road use.
Tire Size & Fitment
What tire size fits a 1930 Jordan 80 Standard?
The 1930 Jordan 80 Standard uses two primary bias-ply tire sizes: 30X6.00 and 6.00-18. Both are period-style fitments associated with this exact vehicle, and the Base sub-model uses these same size options rather than a separate trim-specific tire size.
Choosing between them starts with the wheels and the size convention already on the car. One size is written in antique diameter-by-section form, while the other uses numeric bias-ply notation tied to an 18-inch rim. Checking the wheel diameter and any existing tire markings helps ensure the replacement matches the car's actual setup.
What size rim does a 1930 Jordan 80 Standard use?
The 1930 Jordan 80 Standard uses an 18-inch rim with its 6.00-18 fitment, and the vehicle's tire fitment centers on that 18-inch wheel diameter. That makes wheel confirmation especially important before selecting a replacement tire for a pre-war car that may have seen changes over the decades.
An 18-inch wheel does not automatically settle the full tire decision, because this Jordan also uses the 30X6.00 size format. Owners should confirm the wheel itself, compare the markings on the current tires, and make sure the tire choice matches both the rim and the vehicle's intended appearance. Older collector cars can carry mixed parts, so visual inspection matters.
What does 30X6.00 mean on a 1930 Jordan 80 Standard?
30X6.00 is an antique diameter-by-section tire size. The 30 refers to the tire's approximate overall diameter in inches, while 6.00 refers to its section width in inches. On a 1930 Jordan 80 Standard, that marking represents a period bias-ply sizing style common to earlier automotive applications.
That matters because this notation reads differently from later numeric bias-ply sizes such as 6.00-18. Owners replacing old tires should not assume the two formats are interchangeable without checking the wheel, current fitment, and the way the tire sits within the fender and steering clearance. Vintage size markings often require a little more confirmation than modern radial sizes.
Choosing the Right Tire
What should I consider when choosing a 30X6.00 or 6.00-18 tire for a 1930 Jordan 80 Standard?
Start with the exact size used on the car, since the 1930 Jordan 80 Standard accepts both 30X6.00 and 6.00-18 in bias-ply construction. The choice is not about using a modern substitute here; it is about matching the wheel setup and choosing the period-style tire notation that belongs on the vehicle.
After confirming size, think about how the car will be used. A restoration-focused owner may want the tire size format that best matches the vehicle's existing presentation, while a touring-minded owner still needs to stay within the correct vintage fitment. Wheel condition, clearance, and overall consistency across all four corners should be checked before final selection.
How do I choose between the available 30X6.00 and 6.00-18 tires for a 1930 Jordan 80 Standard?
The first step is determining which size notation belongs on the car's current wheel and tire setup. The 1930 Jordan 80 Standard uses both 30X6.00 and 6.00-18 as bias-ply fitments, so the decision is mainly about matching the wheel diameter and the vintage size convention already in use.
A close inspection of the existing tires, wheels, and any restoration records can help settle the choice. On a pre-war collector car, appearance often matters almost as much as fitment, so owners usually want a replacement that looks appropriate as well as fits correctly. Consistency across the axle and proper clearance during steering travel should be part of the final check.
What rim-fitment details should I compare when choosing tires for a 1930 Jordan 80 Standard?
Wheel diameter is the key rim-fitment detail on a 1930 Jordan 80 Standard, especially because one of its primary sizes is 6.00-18. That 18-inch reference should match the actual wheel before any tire is selected, and older cars should always be inspected carefully rather than relying on assumption.
Beyond diameter, the wheel's condition and the way the tire seats on the rim deserve attention. A collector vehicle may have replacement wheels, repaired rims, or parts swapped over many decades. Tire selection should also leave proper clearance at the fender, suspension, and steering components so the finished setup suits both the car and its intended road use.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Jordan 80 Standard?
For a period-style 1930 Jordan 80 Standard, the right starting point is one of its correct bias-ply sizes: 30X6.00 or 6.00-18. Both belong to the vehicle's vintage fitment story, so the better choice depends on which size notation matches the wheels and the historical presentation already established on the car.
Owners pursuing a detailed restoration often want the tire markings and overall look to align with the era of the vehicle, not just the dimensions. If exact originality is important, compare the car against marque references, restoration photos, or period documentation. That extra step helps keep appearance decisions grounded while staying within the correct fitment family.
Does correct tire fitment matter for a 1930 Jordan 80 Standard restoration?
Correct tire fitment matters a great deal on a 1930 Jordan 80 Standard because the tires are a visible part of the car's stance, proportions, and pre-war character. Using the proper bias-ply size family helps preserve the look the vehicle is meant to carry and avoids introducing an obviously mismatched presentation.
Fitment also affects practicality. A tire that does not suit the wheel or the car's clearance can create problems even if it looks close at first glance. On a restoration, the best approach is to confirm the wheel diameter, compare the existing tire markings, and keep the finished set consistent so the car looks settled and drives as intended.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Jordan 80 Standard?
Yes, modifications can affect tire fitment on a 1930 Jordan 80 Standard. If the car has replacement wheels, brake changes, suspension work, or body repairs that altered clearances, the original bias-ply size choices still need to be checked against the vehicle as it sits today rather than assumed from age alone.
Even small changes can influence how a vintage tire clears the fender, steering linkage, or suspension at full travel. A careful inspection should confirm wheel diameter, tire-to-body spacing, and any signs that the car no longer carries its original wheel setup. That matters on older restorations and long-owned collector cars just as much as on recently modified vehicles.
What should I inspect before driving a 1930 Jordan 80 Standard on new tires?
Before driving a 1930 Jordan 80 Standard on new tires, inspect the wheels, lug hardware, valve stems, and overall tire seating on the rims. The tires themselves should be checked for proper inflation, even sidewall appearance, and adequate clearance around the fenders, suspension, and steering components once mounted.
A short initial drive followed by a second inspection is a smart step on a collector car. That follow-up helps catch rubbing, settling, or any mounting issue before the car is used more seriously. It is also wise to confirm that the brake system, steering, and suspension are in sound condition, since fresh tires can reveal problems that older tires masked.
How should tires on a collector 1930 Jordan 80 Standard be maintained?
Tires on a collector 1930 Jordan 80 Standard should be maintained with regular pressure checks, visual inspections, and careful storage habits. Bias-ply tires on a low-use pre-war car deserve close attention for sidewall cracking, flat spotting, cuts, bulges, and slow air loss, especially after long periods of sitting.
Storage conditions make a real difference. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. It also helps to roll the car periodically or move it slightly during long storage periods. Before any longer outing, inspect both the tire condition and the wheel hardware rather than relying on appearance alone.
