The 1928 Chrysler 72 Series came from a period when American cars were rapidly becoming more refined, more capable, and better suited to regular road use beyond short local driving. That makes tire choice especially important today, because a pre-war car like this depends heavily on proper sizing and period-appropriate construction to look right and drive with the character owners expect. The 1928 Chrysler 72 Series uses bias-ply tires, with two fitment conventions appearing here: 30X6.00 and 6.00-18. The key decision is confirming which wheel and tire sizing system your car is set up for, then choosing a tire that suits restoration goals and road-use plans.
Which Tire Size Is Right for The 1928 Chrysler 72 Series
The 1928 Chrysler 72 Series uses two primary tire sizes, and the first step is identifying which wheel and sizing convention your car is using. Both fitments are bias-ply, but one follows an antique diameter-by-section format and the other uses a numeric bias-ply format tied to an 18-inch rim, so wheel confirmation matters before choosing a tire.
In a size like 30X6.00, the first number refers to the tire's approximate overall diameter in inches, while the second refers to its nominal section width. That format is common on earlier vehicles and helps preserve the tall, upright tire profile that suits a late-1920s Chrysler. This is a bias-ply fitment, so the buyer focus stays on retaining the proper period-style construction and overall presentation rather than moving into modern sizing conventions. It is the right size to evaluate when the car is still using the wheel and tire setup associated with this older measurement style.
A size marked 6.00-18 uses a vintage numeric bias-ply system, where 6.00 represents nominal section width in inches and 18 identifies the rim diameter. For a 1928 Chrysler 72 Series, that ties tire choice directly to an 18-inch wheel and keeps the vehicle in a traditional bias-ply construction. This size makes the most sense when the car is equipped for the later numeric bias-ply convention rather than the older diameter-by-section format. Before selecting a tire, confirm the actual wheel diameter and current wheel setup on the car.
Fitment is straightforward here because the covered sub-model uses the same pair of bias-ply tire sizes. The important step is not choosing between trims, but confirming which wheel and tire-size convention your particular car is wearing before ordering replacement tires.

Frequently Asked Questions
These FAQs focus on the actual tire sizes used on the 1928 Chrysler 72 Series, how the two fitment conventions differ, and what to inspect on a pre-war car before putting it back on the road.
Tire Size & Fitment
What tire size fits a 1928 Chrysler 72 Series?
The 1928 Chrysler 72 Series uses two primary bias-ply tire sizes: 30X6.00 and 6.00-18. Those are not simply alternate spellings of the same modern tire size. They represent two vintage sizing conventions, so the correct choice depends on the wheel and tire setup currently on the car.
A careful look at the wheel diameter and the markings on the existing tires is the best starting point. The 6.00-18 size is tied to an 18-inch rim, while 30X6.00 uses an older diameter-by-section format. On a restored or long-stored Chrysler, confirm what is actually mounted before replacing anything.
What size rim does a 1928 Chrysler 72 Series use?
An 18-inch rim is associated with the 6.00-18 fitment for the 1928 Chrysler 72 Series. That rim diameter is the critical reference point when the car is using the numeric bias-ply size. The 30X6.00 fitment is presented in an older format that emphasizes overall tire diameter and section width.
Wheel verification matters on cars of this age because many have been serviced, restored, or changed over the decades. Measure the rim, inspect the wheel itself, and compare it to the tire size now installed. That step helps prevent ordering a tire that matches the car in theory but not the actual wheel setup.
Does the 1928 Chrysler 72 Series 6 Cyl. use the same tire size?
Yes. The 1928 Chrysler 72 Series 6 Cyl. uses the same two primary bias-ply tire sizes associated with this model: 30X6.00 and 6.00-18. The fitment question is not about a different sub-model specification, but about which of those two vintage sizing systems your particular car is set up to use.
That means the next step is confirming the wheels already on the car rather than trying to sort through trim-level differences. Check the tire sidewall markings, confirm wheel diameter, and look for any prior restoration or replacement work. On a pre-war vehicle, those details matter more than the sub-model name alone.
Choosing the Right Tire
What should I consider when choosing a 30X6.00 or 6.00-18 tire for a 1928 Chrysler 72 Series?
Start with the correct primary size for the wheel setup on your 1928 Chrysler 72 Series. Both 30X6.00 and 6.00-18 are bias-ply fitments, so the main decision is confirming which sizing convention belongs on your car before thinking about appearance, usage, or restoration priorities.
Once the size is confirmed, consider how the car will be used. A vehicle built for shows may prioritize a traditional period-style presentation, while a car driven regularly still needs the same size accuracy with close attention to wheel condition and overall tire age. Correct fitment always comes before appearance preferences.
How do I choose between the available 1928 Chrysler 72 Series tire sizes?
Choosing between the available tire sizes is really a matter of choosing the right fitment for the wheels on the car. The 30X6.00 size follows an antique diameter-by-section format, while 6.00-18 is a numeric bias-ply size that uses an 18-inch rim reference.
That distinction matters because vintage cars are often found with replacement wheels, mixed parts, or long-ago service changes. Read the current tire markings, measure the wheel where needed, and avoid assuming that every 1928 Chrysler 72 Series still carries its original setup. Correct identification prevents an expensive mismatch.
What rim-fitment details should matter when choosing tires for a 1928 Chrysler 72 Series?
Rim diameter is the first detail to confirm, especially if the car may use the 6.00-18 size. On a 1928 Chrysler 72 Series, the tire size must correspond to the actual wheel mounted on the vehicle. Vintage size notation can look unfamiliar, but the wheel still determines the fitment.
Beyond diameter, inspect the wheel for age, damage, and past repairs before mounting new tires. A collector car that has sat for years may also need attention to rim condition, hardware, and overall straightness. Tire replacement is a good time to confirm the entire wheel-and-tire assembly is ready for safe road use.
Restoration & Appearance
Which tire should I choose for a period-style 1928 Chrysler 72 Series?
For a period-style 1928 Chrysler 72 Series, the right starting point is the correct bias-ply fitment in the proper vintage size system for the car's wheels. That means choosing between 30X6.00 and 6.00-18 based on the actual setup rather than treating them as interchangeable modern alternatives.
Appearance on a late-1920s car is shaped strongly by tire proportions, sidewall presence, and construction style. Buyers pursuing an especially accurate restoration should compare the car against marque references, period photos, and restoration records. Even when two sizes are associated with the model, the correct presentation depends on the vehicle's own wheel arrangement.
Does correct tire fitment matter for a 1928 Chrysler 72 Series restoration?
Yes, correct tire fitment matters a great deal on a 1928 Chrysler 72 Series restoration. Tires affect stance, visual balance, and the overall authenticity of the finished car as much as many more obvious restoration details. On a pre-war vehicle, the wrong size can change the look immediately.
Proper fitment also affects how the car sits on its wheels and how the restoration reads to knowledgeable enthusiasts. Matching the tire to the wheel setup, preserving the intended bias-ply character, and checking that the size convention is correct all help the car look cohesive. Those details are especially important on open, upright pre-war designs.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 Chrysler 72 Series?
Yes. Modifications can affect tire fitment on a 1928 Chrysler 72 Series, especially if the car has replacement wheels, altered suspension height, brake updates, or bodywork changes. Even when using a correct vintage tire size, changes elsewhere on the vehicle can alter clearance or create a mismatch between the tire and wheel.
A modified car should be checked at the wheel openings, steering range, and suspension travel before new tires are chosen. Older vehicles also sometimes carry mixed components from earlier repairs. Looking closely at what is actually on the car helps avoid rubbing, uneven stance, or a tire that does not suit the current setup.
What should I inspect before driving a 1928 Chrysler 72 Series on new tires?
Before driving a 1928 Chrysler 72 Series on new tires, inspect the wheels, valve hardware, and the general condition of the suspension and steering components. A fresh set of tires cannot compensate for bent rims, worn steering parts, or a chassis that has been sitting for a long period without regular maintenance.
It also makes sense to confirm tire pressure, check for any signs of interference, and recheck the mounting after the first short drive. On a pre-war collector car, road-readiness is about the whole rolling assembly. Tire condition, wheel condition, and mechanical condition all need to work together before regular use.
How should 30X6.00 or 6.00-18 tires on a collector 1928 Chrysler 72 Series be maintained?
Collector-car tires on a 1928 Chrysler 72 Series should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even when tread wear is minimal, age and inactivity can be harder on vintage tires than mileage. Sidewall cracking, flat spotting, and air loss deserve attention before every outing.
Storage conditions make a difference as well. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between drives. A Chrysler that is used infrequently should still have its tires inspected on a schedule, because older vehicles often age their tires long before they wear them out.
