1926 Jordan Tire Fitment Guide

1926 Jordan vehicles use four sizes across two models. The Jordan Gt Line-8 uses 32X6.20 and 650-20, both on 20-inch rims, while the Jordan Line-8 uses 30X6.00 and 6.00-18, both on 18-inch rims. All four sizes are bias-ply fitments, and the sizes are model-specific rather than shared across the entire 1926 Jordan lineup.

That means year and make alone are not enough to choose a tire for a 1926 Jordan. Start by confirming whether your car is a Line-8 or Gt Line-8, then confirm whether the wheels on the car are still the correct diameter for that model. Once those two points are settled, you can narrow the choice to the appropriate size family instead of comparing unrelated tires.

On a 1926 Jordan, 32X6.20 is an antique diameter-by-section size. The 32 refers to the tire’s approximate overall diameter in inches, while 6.20 refers to nominal section width. That differs from later sizing systems that emphasize wheel diameter in the size code itself. For the 1926 Jordan range, this size belongs to the Gt Line-8 and mounts on a 20-inch rim.

Antique-format sizing can look unfamiliar because it describes the tire more by outside diameter and cross section than by modern fitment shorthand. If you see 32X6.20 on a Gt Line-8, treat it as part of that model’s original-era sizing language rather than assuming it cross-references directly to any 18-inch Jordan fitment. Matching the actual wheel diameter remains the first checkpoint before comparing tire options.

On a 1926 Jordan, 650-20 is a numeric bias-ply size. The 6.50 portion indicates nominal section width in inches, and the 20 indicates the rim diameter in inches. Within the 1926 Jordan range, 650-20 is used on the Gt Line-8. It is one of the clearer early sizing systems because the wheel diameter is directly stated in the code.

That makes 650-20 easier for many buyers to interpret than an antique diameter-by-section marking, but it still should not be treated as interchangeable with the Line-8’s 18-inch sizes. If your Jordan wears 20-inch wheels and falls under the Gt Line-8 family, 650-20 is one of the correct sizing paths to investigate. Sidewall appearance can then help refine the final selection.

For 1926 Jordan tires with currently listed product coverage, the 650-20 size is offered in both Blackwall and Wide Whitewall form. Firestone appears in both styles, while Denman and Deka are listed in Blackwall versions. All of these are bias-ply offerings in keeping with the period construction used on 1926 Jordan cars.

Sidewall style often affects the look of a pre-war restoration as much as the size itself. Blackwalls usually suit a more restrained or utility-minded presentation, while whitewalls can emphasize luxury styling and period visual drama. For a 1926 Jordan, the right choice depends on how you want the finished car to present and what standards your restoration or show goals call for.

Firestone, Denman, and Deka all have products listed for 1926 Jordan fitment in the 650-20 size. Firestone includes both Blackwall and Wide Whitewall versions, while Denman and Deka are represented in Blackwall bias-ply offerings. All of the listed products stay within the period-appropriate bias-ply construction expected for a 1926 Jordan.

Brand choice on a pre-war car often comes down to the look you want and the specific size you need rather than broad marketing claims. If your Jordan is a Gt Line-8 using 650-20 tires, comparing the available brands by sidewall style, load listing, and intended visual character is the practical next step. For other 1926 Jordan sizes, begin by confirming the exact model-specific fitment first.

On the 1926 Jordan Gt Line-8, Firestone 650-20 tires are offered in both Blackwall and 3.75-inch Wide Whitewall versions, while Denman and Deka 650-20 tires are listed as Blackwalls. Firestone’s listed 650-20 products carry a max load figure of 2120 pounds at 60 psi and a rim width range of 3.00 to 5.00 inches. The Denman and Deka entries are presented as classic truck-oriented bias-ply products.

That makes the comparison less about one tire being universally better and more about whether you want a passenger-car presentation or a more utilitarian blackwall look within the same size. Owners restoring a visually upscale Gt Line-8 may lean toward the whitewall Firestone, while others may prefer a plain blackwall appearance. Wheel width and the intended style of the finished car should guide the final decision.

Rim width guidance is listed for 1926 Jordan in the 650-20 size, where the available products specify a usable rim width range of 3.00 to 5.00 inches on a 20-inch rim. The 1926 Jordan Gt Line-8 is the model associated with that size. Other 1926 Jordan sizes here do not carry a published rim width range in the available product set.

Rim width matters because even when the tire size code appears correct, a wheel that is too narrow or too wide can affect section shape and how the tire sits on the rim. On a 1926 Jordan Gt Line-8, checking the wheel against the 650-20 rim width range is a smart setup step before choosing between available products. For the 18-inch Line-8 sizes, compare your wheel carefully against the actual tire you intend to run.

All 1926 Jordan sizes covered here are bias-ply tires from a pre-war application, but tube marking is not shown uniformly in the available listings. The currently listed 650-20 products do not include a TT or TL marking in the size field, so the safest approach is to verify the specific tire’s sidewall marking and wheel type before finalizing setup. That is especially important on original-style multi-piece or early drop-center wheels.

On a 1926 Jordan, tube use is often tied as much to the wheel itself as to the tire size. If the car retains original wheels, inspect the rim design, condition, and valve hardware so the tire and tube arrangement work together correctly. A pre-war wheel should never be assumed to be tubeless-ready simply because a modern reproduction tire happens to exist in a matching size.

A 1926 Jordan should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age rubber. Bias-ply tires are especially prone to developing temporary flat spotting and visible sidewall aging when they sit under load for long periods. Keeping the car clean and the tires at correct operating pressure helps reduce avoidable stress during storage.

For longer layups, move the car periodically so one section of the tire does not stay compressed in the same spot for months at a time. Some owners also use stands to reduce load, but they should support the car properly without twisting the suspension. A stored 1926 Jordan that only comes out occasionally still benefits from regular tire pressure checks and visual inspection between drives.

Tire life on a 1926 Jordan is usually governed more by age than by mileage. Collector tires should be evaluated regularly once they reach the five- to seven-year range, and around ten years is a common point where replacement deserves serious consideration regardless of remaining tread. The DOT date code, if present on the tire, helps determine age, and visual condition remains an important part of the decision.

That matters because many pre-war cars are driven sparingly, so a tire can look barely worn while still being old enough to warrant caution. Sidewall checking, hardening rubber, changes in ride quality, and repeated pressure loss are all reasons to inspect more closely. On a 1926 Jordan, preserving originality should never mean stretching aged tires beyond a reasonable service life.

Tires on a 1926 Jordan should be inspected before every drive and again before any longer outing. Look for sidewall cracking, cuts, tread separation, bulges, embedded objects, and pressure loss, and pay attention to how evenly the tire is sitting on the wheel. Pre-war bias-ply tires can show age and storage effects before they show meaningful tread wear.

A thorough check is especially important when the car has been sitting or when the route includes sustained road speeds. Inspect valve stems carefully and, where tube-type fitment is being used, make sure slow leaks are not being overlooked as normal vintage-car behavior. The spare should be checked too, since a 1926 Jordan often depends on it more than a modern car would on a long drive.

The 1926 Jordan Gt Line-8 would have been a bias-ply application when new, which aligns with the sizes used here: 32X6.20 and 650-20 on 20-inch rims. That construction type is consistent with the period, long before radials became normal passenger-car equipment in the American market. Specific original brand fitment could vary by supply, selling dealer, and market expectations, so size and construction are the more reliable authenticity markers.

For a restoration, the key is to stay within the correct bias-ply size family for the Gt Line-8 and then choose the sidewall presentation that best suits the car’s intended finish. If the car is headed for formal judging, consult Jordan specialists or marque clubs for model-specific guidance on cosmetic details. Those sources can help settle questions about what would look most authentic on your particular car.

Correct tire fitment matters a great deal on a 1926 Jordan because judges and knowledgeable enthusiasts notice size, construction type, and sidewall appearance quickly. A car from this period is expected to wear bias-ply tires in the correct size family for its model, and a visibly incorrect rim diameter or an obviously out-of-era sidewall treatment can disrupt the car’s authenticity. Even on non-judged cars, the wrong fitment changes the overall stance.

That does not mean every restored 1926 Jordan must be prepared for concours rules, but it does mean the tire should support the story the car is telling. A preservation-minded car, a touring car, and a show-focused restoration may make different choices within the correct model-specific size path. Event rules vary, so the final standard should come from the judging body or marque community you plan to satisfy.

On a 1926 Jordan, antique-size markings such as 32X6.20 and 30X6.00 describe the tire primarily by overall diameter and nominal section width, while numeric sizes such as 650-20 and 6.00-18 emphasize nominal width and wheel diameter. Both systems appear within the 1926 Jordan lineup, and all are bias-ply applications tied to specific models. The Gt Line-8 uses the 20-inch pair, while the Line-8 uses the 18-inch pair.

For restoration work, the difference is more than just how the sidewall reads. Antique-format sizes often appeal to owners who want the tire marking itself to look era-correct to the period, while numeric sizes can be more immediately recognizable when checking wheel fitment. On a 1926 Jordan, the important point is not to mix the model-specific 20-inch and 18-inch paths simply because the sizing systems look related.

1926 Jordan tires can be suitable for road use when they are the correct size, in good condition, properly inflated, and matched to sound wheels, but they remain bias-ply tires designed around pre-war vehicle dynamics. No speed rating markings are shown in the currently listed 1926 Jordan products here, so safe road use should be approached with the car’s age, braking ability, steering geometry, suspension condition, and overall mechanical health in mind rather than tire size alone.

A well-sorted 1926 Jordan used responsibly can be enjoyable on secondary roads and moderate highway stretches, but sustained high-speed use is not the right benchmark for a car of this era. The real safety decision comes from the full condition of the car, not just the presence of fresh tires. Before any extended drive, make sure the chassis and steering are as trustworthy as the rubber touching the road.

Inflation pressure on a 1926 Jordan should follow the size and tire actually fitted, not a one-number rule for the whole make. Among the listed products, 650-20 Firestone tires carry a maximum load and pressure figure of 2120 pounds at 60 psi. That is a maximum-rated figure for that tire, not automatically the pressure your Jordan should be run at in normal service.

For actual operating pressure, start with the original Jordan literature if available and then compare it with the tire manufacturer’s guidance for the specific reproduction tire on the car. Pressure affects ride, steering feel, and tread behavior on a bias-ply vehicle more than many owners expect. Never transfer a pressure figure from the 650-20 Gt Line-8 fitment to the 18-inch Line-8 sizes without checking the exact tire first.

Before a longer drive in a 1926 Jordan, inspect each tire for cracking, cuts, bulges, irregular wear, and proper inflation, and make sure the spare is roadworthy as well. Check that the wheel hardware is secure, the valve stems are in good condition, and any tube-type setup is holding pressure correctly. On a pre-war car, tire condition is only one part of a broader safety check that should also include brakes, steering, wheel bearings, and fluids.

A longer outing puts more heat and continuous load into the tires than a short local drive, so small problems become more important. It is wise to confirm that the car tracks properly, does not shimmy, and has no recurring pressure loss before committing to distance. A 1926 Jordan rewards preparation, and a careful pre-drive routine usually prevents the kind of roadside trouble that vintage owners remember for the wrong reasons.
