The 1930 Marmon 79 Series came from an era when American luxury cars were defined by advanced engineering, smooth straight-eight power, and formal road presence. Marmon stood apart as a technically minded Indianapolis builder, and the 79 Series reflects that pre-war character in both appearance and running gear. Tire fitment for the 1930 Marmon 79 Series centers on two bias-ply sizes, 31X6.00 and 600-19, both tied to a 19-inch wheel setup. That keeps the decision focused less on modern sizing confusion and more on preserving the right stance, sidewall look, and period-style construction. For restoration-minded owners, wheel confirmation and visual presentation matter just as much as the size itself.
Which Tire Size Is Right for The 1930 Marmon 79 Series
The 1930 Marmon 79 Series uses two primary tire sizes, and both are bias-ply fitments tied to the same 19-inch wheel diameter. The first step is confirming which size is on the car now and whether the wheel and overall presentation match 31X6.00 or 600-19, especially on a restoration or a car that may have seen wheel changes over time.
31X6.00 is an antique diameter-by-section size, which means the first number refers to the tire's approximate overall diameter and the second refers to its nominal section width. On the 1930 Marmon 79 Series, this is a bias-ply fitment that suits the formal, upright tire profile expected of a premium pre-war automobile. Its format is older than later numeric sizing systems, so owners often encounter it on cars restored with an emphasis on period appearance. Choosing this size calls for careful wheel confirmation and attention to how the tire's diameter and visual proportions suit the car's current setup.
600-19 is a numeric bias-ply size in which 600 represents a nominal 6.00-inch section width and 19 identifies the rim diameter in inches. For a 1930 Marmon 79 Series, it delivers a traditional pre-war bias-ply presentation and is available in a restoration-oriented Lester Classic Bias Ply offering with a Wide Whitewall sidewall style. That makes it especially relevant for owners who want a traditional luxury-car look rather than a purely utilitarian finish. It is worth evaluating closely against the wheels on the car and the appearance goal of the restoration before making a final choice.
Tire fitment is straightforward across the covered 1930 Marmon 79 Series sub-model, since the same two bias-ply sizes are associated with it. Checking the exact sub-model still matters because it helps confirm that the car remains on the wheel and tire setup intended for this chassis.

1930 Marmon 79 Series 8 Cyl.
The 1930 Marmon 79 Series 8 Cyl. uses the same two bias-ply fitment paths found within this model range, so the main question is which of those sizes matches the wheels and presentation of the car in front of you. That makes selection more about confirming the existing setup and choosing the right period-style replacement than sorting through trim-specific tire differences.
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 Marmon 79 Series?
The 1930 Marmon 79 Series uses two primary tire sizes: 31X6.00 and 600-19. Both are bias-ply fitments, and both relate to the same general 19-inch wheel setup used on this model range, so the key difference is the sizing convention and the way the tire is identified on the car.
The practical step is confirming which size is actually on the Marmon now before choosing a replacement. Pre-war cars are often restored, re-wheeled, or mixed with parts over time, so the sidewall markings, wheel dimensions, and overall tire proportions should all be checked rather than assuming either size belongs on every individual car.
What size rim does a 1930 Marmon 79 Series use?
The 1930 Marmon 79 Series uses a 19-inch rim diameter. That rim diameter is directly associated with the 600-19 fitment, and the vehicle's tire inventory points to a 19-inch wheel setup across the covered fitments for this model.
Rim diameter is the first measurement to verify before ordering tires for a pre-war car. On an older restoration, the current wheels may not match what the car originally carried, and diameter alone is not the whole story, so it also helps to confirm wheel width, bead condition, and whether the tire's sidewall style suits the look you want.
Do all 1930 Marmon 79 Series sub-models use the same tire size?
The covered 1930 Marmon 79 Series sub-model uses the same two tire sizes associated with this vehicle: 31X6.00 and 600-19. That means fitment is consistent within the listed 79 Series 8 Cyl. application rather than split by separate trim-specific tire sizes.
Even with shared fitment, the right choice still depends on the car's present wheel and restoration configuration. A Marmon that has been restored for show may favor one style of presentation, while a driver may simply need the size that matches its current wheels and existing sidewall markings.
Choosing the Right Tire
What should I consider when choosing a 600-19 tire for a 1930 Marmon 79 Series?
Start with the fundamentals: correct size, bias-ply construction, and 19-inch wheel compatibility. For the 1930 Marmon 79 Series, a 600-19 tire should also be chosen with the car's visual character in mind, since sidewall treatment and series style can strongly influence how authentic or formal the finished car looks.
The available 600-19 selection includes a Lester tire in the Lester Classic Bias Ply series with a Wide Whitewall sidewall style. That makes this size especially relevant for owners pursuing a traditional luxury-car presentation, but wheel condition, actual wheel dimensions, and the intended use of the car should still be reviewed before final selection.
What sidewall styles are available for 1930 Marmon 79 Series tires?
The available sidewall style shown for the 1930 Marmon 79 Series is Wide Whitewall in 600-19. On a pre-war luxury automobile, that kind of sidewall treatment can play a major role in the car's finished appearance and may be just as important to the buyer as the size itself.
Sidewall choice should be matched to the way the car is being presented, whether that is a formal restoration look or a more understated touring appearance. It also helps to compare the sidewall treatment to period photos, marque references, and the visual balance of the car's body, wheel covers, and ride height.
What brands offer tires for the 1930 Marmon 79 Series?
Lester is represented in the available 1930 Marmon 79 Series tire selection, specifically in 600-19. The brand appears in a restoration-oriented bias-ply offering that aligns well with the kind of traditional presentation many pre-war luxury car owners want to preserve.
Brand choice is only one part of the decision on a car like this. It should be weighed alongside the actual size used on the vehicle, the wheel dimensions, the sidewall style, and the overall look the owner is trying to achieve rather than treating the brand name alone as the deciding factor.
Restoration & Appearance
Which tire should I choose for a period-style 1930 Marmon 79 Series?
A period-style 1930 Marmon 79 Series tire choice starts with the correct primary fitment, which means staying with one of the two bias-ply sizes used on the car: 31X6.00 or 600-19. That keeps the construction and visual character aligned with the pre-war era instead of shifting the car toward a more modern-looking setup.
The better choice between those two sizes depends on the wheels currently on the vehicle and the appearance goal of the restoration. Owners seeking close historical accuracy should compare the car's existing setup with period references, marque-club guidance, and restoration records before settling on a specific sidewall treatment or size format.
Does correct tire fitment matter for a 1930 Marmon 79 Series restoration?
Correct tire fitment matters a great deal on a 1930 Marmon 79 Series because tire size and construction strongly affect stance, visual proportion, and the overall character of a pre-war luxury automobile. A car from this era can look noticeably different when the tire profile, sidewall treatment, or diameter presentation is out of step with the chassis.
Restoration-minded owners should look beyond the sidewall marking alone and confirm the wheels, the tire's visual shape, and the intended use of the car. Even when two fitments belong to the same model, the one that suits the car best is usually the one that matches both the existing hardware and the restoration objective.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1930 Marmon 79 Series?
Yes, modifications can affect tire fitment on a 1930 Marmon 79 Series even when the tire size itself appears correct. Changes to wheels, suspension height, brake components, or body clearances can alter how a 31X6.00 or 600-19 tire sits and whether it has the clearance needed in normal driving and steering movement.
A pre-war car often passes through many decades of repairs and restoration work, so assumptions can be risky. Checking actual wheel diameter, wheel width, tire-to-fender clearance, and steering clearance on the car is the best way to avoid choosing a tire that matches the sidewall marking but not the current physical setup.
What should I inspect before driving a 1930 Marmon 79 Series on new tires?
Before driving a 1930 Marmon 79 Series on new tires, inspect the wheels, valve hardware, and overall mounting quality, then confirm that the tires are seated properly and inflated appropriately for their intended use. It also helps to verify that nothing in the suspension or steering causes rubbing or uneven tire position at full lock.
A short, careful test drive is the right next step on a collector car of this age. Pay attention to pull, vibration, unusual noise, or any sign of contact inside the fenders, and recheck pressure and visual condition after the first drive so small installation or clearance issues are caught early.
How should 600-19 tires on a collector 1930 Marmon 79 Series be maintained?
600-19 tires on a collector 1930 Marmon 79 Series should be maintained with regular pressure checks, visual inspections, and clean storage conditions. Because older collector cars are often driven infrequently, age-related issues such as sidewall cracking, flat spotting, cuts, or slow air loss can become more important than tread wear alone.
Storage conditions matter almost as much as road use on a pre-war car. Keeping the Marmon away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tire casing, and routine inspections before each outing make it easier to catch deterioration before it turns into a road-use problem.
