The 1930 Jordan T comes from the closing years of the American independent-car era, when distinctive styling and upscale presentation still played a major role in how a car was perceived. For owners of a surviving Jordan today, tire choice is part fitment decision and part period-style presentation. This model uses bias-ply fitments in 28X5.50 and 550-18, centered around an 18-inch wheel setup. That opens the door to traditional blackwall tires as well as restoration-oriented whitewall and double-whitewall choices from brands such as Excelsior, Firestone, BFGoodrich, and Michelin. The key is confirming which of the two size conventions matches the wheels and look your car carries now.
Which Tire Size Is Right for The 1930 Jordan T
The 1930 Jordan T uses two primary tire sizes, and both are bias-ply fitments. Because the two sizes are written in different sizing systems, the first step is confirming whether your car is set up around a flotation-style 28X5.50 tire or a numeric 550-18 tire on an 18-inch rim. Once that is settled, the choice shifts to appearance, brand, and period-style tire series rather than modern construction alternatives.
28X5.50 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 a 1930 Jordan T, this is a bias-ply fitment aimed at the traditional driving feel and visual character expected of an early 1930s automobile. Because this format is less familiar to many modern buyers, it is important to confirm that the wheel and existing tire markings actually match this older sizing convention. This size is best evaluated when the goal is to stay close to an authentic early-car tire format.
550-18 is a numeric bias-ply size, with the 550 indicating an approximate 5.50-inch nominal section width and the 18 indicating an 18-inch rim diameter. For the 1930 Jordan T, this size offers the broadest visible product choice, including blackwall, wide whitewall, and double-whitewall styles across series such as Excelsior Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Michelin Double Rivet. Brand choice, sidewall treatment, and wheel-width compatibility all matter here. This is the size to study closely if your Jordan is already running 18-inch wheels and you want meaningful appearance options.
Fitment is straightforward for the covered 1930 Jordan T sub-model because the same primary tire choices carry across it. Even so, checking the exact sub-model remains worthwhile so the tire size convention on the car now matches the wheel setup and restoration direction.

1930 Jordan T Base
The 1930 Jordan T Base uses the same two bias-ply size paths found on the model overall: 28X5.50 and 550-18. That means the main decision is not trim-based fitment, but confirming which wheel and tire sizing convention the car currently uses before choosing among blackwall or whitewall-style replacements.
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 1930 Jordan T?
The 1930 Jordan T uses two primary bias-ply tire sizes: 28X5.50 and 550-18. Those are not simply two ways of writing the same modern tire size, so the correct choice depends on which sizing convention matches the wheel and tire setup on the car.
A Jordan that still carries period-style wheels may already point clearly to one size or the other through existing tire markings, wheel dimensions, or long-established restoration choices. Checking the tire stamped on the car now, measuring wheel diameter, and confirming clearance before replacement helps prevent ordering a tire that matches the era but not the actual wheel setup.
What size rim does a 1930 Jordan T use?
The 1930 Jordan T uses an 18-inch rim with its 550-18 bias-ply fitment. That size makes the wheel diameter easy to read directly from the tire code, since the final number in 550-18 designates the rim diameter in inches.
The 28X5.50 sizing format is older and expresses approximate tire diameter and section width rather than spelling out the wheel diameter in the same way. Because of that, it is smart to measure the wheel or verify the tire currently on the car before selecting a replacement. Early-car restorations and long-ago wheel changes can leave a Jordan wearing a setup different from what the size code alone might suggest.
What does 550-18 mean on a 1930 Jordan T?
On a 1930 Jordan T, 550-18 is a vintage numeric bias-ply size. The 550 refers to an approximate 5.50-inch nominal section width, and the 18 refers to the rim diameter in inches.
That matters because a 550-18 tire is selected around an 18-inch wheel, not just overall appearance. It also opens up several traditional product choices, including blackwall, wide whitewall, and double-whitewall styles. Once the size is confirmed, the next steps are comparing wheel-width compatibility, reviewing the sidewall look that suits the car, and making sure the tire clears fenders and steering components.
Choosing the Right Tire
What should I consider when choosing a 550-18 tire for a 1930 Jordan T?
Start with the basics: confirm that 550-18 is the size actually used on your 1930 Jordan T and that the car is running 18-inch wheels. From there, the biggest differences are brand, tire series, sidewall treatment, and wheel-width specification.
A blackwall tire gives a more understated presentation, while wide whitewall and double-whitewall versions create a more formal restoration look. Product details also vary by rim-width fitment and load figures, with examples such as 1000@32 psi and 1125@32 psi appearing within this size. Matching the tire to the wheel, the intended appearance, and the way the car will be used is more important than chasing one style on looks alone.
What sidewall styles are available for 1930 Jordan T tires?
For 550-18 fitment on a 1930 Jordan T, available sidewall styles include blackwall, wide whitewall, and double-whitewall. Those choices can change the visual character of the car substantially even when the tire size remains the same.
Blackwall tires tend to suit owners who want a restrained, mechanical early-car look, while whitewall treatments bring more visual emphasis to the wheel and tire package. Because sidewall style does not change the need for correct size and wheel compatibility, appearance should be chosen only after confirming fitment. On a restoration-minded Jordan, the sidewall treatment is often one of the final details that ties the whole stance together.
What brands offer tires for the 1930 Jordan T?
The 1930 Jordan T has 550-18 tire choices from Excelsior, Firestone, BFGoodrich, and Michelin. Those brands appear across several period-style bias-ply offerings rather than one single visual or series approach.
That variety gives owners room to compare a simpler blackwall presentation against more formal whitewall styles, while also reviewing differences in tire series and wheel-width specifications. It is usually more helpful to narrow the decision by fitment and appearance first, then compare brands within that group. A Jordan intended for shows may call for a different visual emphasis than one being prepared for regular touring use.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Jordan T?
A period-style 1930 Jordan T starts with the correct primary size convention on the car, either 28X5.50 or 550-18, and with bias-ply construction. After that, the choice becomes one of visual character, especially if the car uses 550-18 where blackwall, wide whitewall, and double-whitewall options are available.
Owners pursuing strict historical accuracy should compare the tire choice against marque references, older photos, surviving-car evidence, and restoration documentation for the specific vehicle. For many buyers, though, a traditional bias-ply tire in the right size with a sidewall style that fits the car's presentation is the practical path. The most convincing result usually comes from balancing appearance, wheel compatibility, and intended road use.
Does correct tire fitment matter for a 1930 Jordan T restoration?
Correct tire fitment matters on a 1930 Jordan T because the tire is a large visual element and a major part of how the car sits. Using the right size family and an appropriate bias-ply construction helps preserve the proportions and period feel expected of an early 1930s automobile.
Appearance is only part of the issue. A mismatch between tire size and wheel setup can affect how the car steers, how it fills the fenders, and whether the finished restoration looks coherent. Even when the goal is a show-oriented result, it is worth checking wheel dimensions, present tire markings, and overall stance before choosing between the two accepted size conventions.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Jordan T?
Yes. Any change to wheels, suspension height, brake components, or body clearance can affect tire fitment on a 1930 Jordan T, especially on a vehicle this old where parts may have been changed more than once over its life.
An altered wheel can change the size path from what the car once used, and even a correct-looking tire may be wrong for the wheel now installed. Before replacing tires, inspect actual rim diameter and width, then turn the steering through full travel and check clearance at the fenders and suspension. That extra verification is especially important when choosing between 28X5.50 and 550-18 rather than assuming either one belongs on every surviving car.
What should I inspect before driving a 1930 Jordan T on new tires?
Before driving a 1930 Jordan T on new tires, inspect the wheels, valve stems, mounting surfaces, and overall tire seating. Then check inflation, look for any contact points during steering movement, and confirm that the tires clear the body and suspension at rest.
A car from this era also benefits from a wider mechanical walk-around before road use. Look at wheel bearings, steering play, brake function, and any signs that an old wheel or rim edge could damage a fresh tire. Early collector cars often spend long periods parked, so the first drive after tire installation should be short and deliberate, with a follow-up pressure and visual check once the car returns.
How should 550-18 tires on a collector 1930 Jordan T be maintained?
550-18 tires on a collector 1930 Jordan T should be maintained with regular pressure checks, routine visual inspections, and careful storage habits. Even a lightly driven antique car can develop tire issues from age, underinflation, heat, sunlight, or long periods of sitting.
Look over the tread and sidewalls for cracking, cuts, bulges, or uneven wear before each season and before any longer outing. Keeping the car in a cool, dry space away from prolonged sun and ozone sources helps protect the rubber over time. A Jordan that is rarely driven still needs periodic inspection, because collector-car tires can age out physically long before they wear out from mileage.
