The 1928 Velie 66 Series comes from the closing years of the independent American automaker era, when durable touring cars still rode on tall, narrow tires that were as much a part of the car’s stance as its body lines. For owners of this exact model, tire fitment centers on two bias-ply sizes: 30X5.25 and 5.25-20. Those two sizes represent different vintage sizing systems, so the first step is understanding which one matches the car’s wheel setup. Once that is settled, the focus shifts to preserving proper period-style appearance, confirming wheel dimensions, and inspecting the chassis and tires carefully before returning the car to road use.
Which Tire Size Is Right for The 1928 Velie 66 Series
The 1928 Velie 66 Series uses two primary tire sizes, and they do not share the same rim diameter. That makes wheel confirmation the first step before choosing a tire, especially on a vehicle that may have seen wheel changes over the decades. Both sizes are bias-ply fitments, but they come from different vintage sizing conventions, so identifying the exact wheel setup matters more here than simply matching the sidewall marking.
30X5.25 is an antique diameter-by-section size, meaning the first number refers to the tire’s approximate overall diameter and the second refers to its section width. On the 1928 Velie 66 Series, this is a bias-ply fitment that reflects an earlier tire-sizing convention often seen on late-1920s vehicles. Because this format differs from later numeric bias-ply sizing, it is important to match the tire to the actual wheel diameter rather than assuming the first number identifies the rim. This size is most relevant for owners preserving a very early period-style presentation and wheel setup.
5.25-20 is a numeric bias-ply size, with 5.25 indicating nominal section width in inches and 20 identifying the rim diameter. On a 1928 Velie 66 Series, this format points to a tall, narrow vintage tire suited to the car’s original-era proportions and steering geometry. Its sizing convention is more familiar than the antique diameter-by-section format, but it still calls for careful wheel confirmation on a nearly century-old vehicle. This size is the one to evaluate if the car is running 20-inch wheels or has already been set up around later vintage numeric markings.
Fitment is straightforward here because the covered sub-model uses the same two bias-ply tire sizes already associated with the 1928 Velie 66 Series. Even so, checking the exact wheel diameter remains important before selecting between the two vintage size formats.

1928 Velie 66 Series 6 Cyl.
The 1928 Velie 66 Series 6 Cyl. uses the same pair of bias-ply tire sizes found at the model level, so the main issue is not trim variation but wheel confirmation. Tire selection comes down to matching the car’s actual rim setup and choosing a period-style bias-ply tire that suits restoration and road-use goals.
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 vintage tire sizes used on the 1928 Velie 66 Series, how to confirm the correct wheel setup, and what to consider for restoration appearance, fitment checks, and safe road use.
Tire Size & Fitment
What tire size fits a 1928 Velie 66 Series?
The 1928 Velie 66 Series uses two primary bias-ply tire sizes: 30X5.25 and 5.25-20. Those are not simply two ways of writing the same size, because they come from different vintage sizing systems and use different rim diameters on this application.
The practical next step is to confirm which wheels are actually on the car before choosing a tire. Many collector vehicles have had wheel, hub, or tire changes over time, so the sidewall marking should match the wheel setup instead of being chosen by appearance alone.
What size rim does a 1928 Velie 66 Series use?
The 1928 Velie 66 Series uses two rim diameters across its primary tire fitments: 5.0 inches with 30X5.25 and 20.0 inches with 5.25-20. That difference is central to the tire decision, because each size belongs to a different wheel setup.
A buyer should measure and verify the actual wheel before ordering a tire, especially on a vehicle from the late 1920s. Old sidewall markings, wheel swaps, and restoration changes can create confusion, and matching the tire to the correct rim diameter is more important than matching the car’s overall era.
What does 30X5.25 mean on a 1928 Velie 66 Series?
30X5.25 is an antique diameter-by-section size. The 30 refers to the tire’s approximate outside diameter, while 5.25 refers to section width, so this format does not use the first number to identify rim diameter the way later tire sizes often do.
That makes this size easy to misread if you are more familiar with later numeric bias-ply or modern radial formats. On a 1928 Velie 66 Series, the safest approach is to confirm the wheel itself, then choose the tire that matches both the vintage sizing system and the rim setup already on the car.
Choosing the Right Tire
What should I consider when choosing a tire for a 1928 Velie 66 Series?
Start with the actual wheel diameter and the tire size already associated with that wheel setup, because the 1928 Velie 66 Series uses both 30X5.25 and 5.25-20 bias-ply tires. The right choice depends first on matching the tire to the wheel, not on choosing between two interchangeable options.
After that, think about how the car will be used. A restoration-oriented car may prioritize a period-style presentation, while a regularly driven collector vehicle still needs careful attention to wheel condition, tire age, tread and sidewall health, and general chassis readiness before road use.
How do I choose between 30X5.25 and 5.25-20 tires for a 1928 Velie 66 Series?
The choice between 30X5.25 and 5.25-20 depends on which wheel setup is on the car. They are both bias-ply sizes for the 1928 Velie 66 Series, but they belong to different vintage sizing systems and are tied to different rim diameters.
That means the decision should be made with the wheel in front of you rather than by guessing from the vehicle year alone. Checking the rim diameter, existing tire markings, and overall restoration setup will point you toward the correct size and help avoid ordering a tire that cannot be mounted properly.
What rim-fitment details matter when choosing 1928 Velie 66 Series tires?
Rim diameter matters most on the 1928 Velie 66 Series because its two primary tire sizes do not use the same wheel size. A 30X5.25 tire corresponds to a different rim setup than a 5.25-20 tire, so correct identification comes before any appearance or restoration decision.
Wheel condition also deserves attention on a vehicle of this age. Inspect for damage, corrosion, out-of-round issues, and any signs that the wheel has been modified, then confirm that the tire size and wheel configuration match before moving forward with mounting or road use.
Restoration & Appearance
Which tire should I choose for a period-style 1928 Velie 66 Series?
A period-style 1928 Velie 66 Series should begin with the correct primary bias-ply size for the wheels on the car, either 30X5.25 or 5.25-20. Both sizes suit the late-1920s character of the vehicle, but they are not interchangeable because they correspond to different wheel setups.
Appearance should follow fitment, not replace it. Once the wheel diameter is confirmed, a bias-ply tire in the correct vintage format will preserve the tall, narrow look that complements the car’s proportions, while owners pursuing exact historical accuracy should also consult marque-specific restoration references.
Does correct tire fitment matter for a 1928 Velie 66 Series restoration?
Correct tire fitment matters a great deal on a 1928 Velie 66 Series restoration because the tire contributes heavily to the car’s stance, visual balance, and mechanical compatibility. Choosing between 30X5.25 and 5.25-20 is not a cosmetic detail alone; it is tied directly to the wheel setup.
A mismatch can affect how the car sits, how the wheels are presented, and whether the tire mounts properly in the first place. On a restoration of this era, getting the basic size and construction right is usually the most important step before considering finer appearance details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 Velie 66 Series?
Yes. Modifications can affect tire fitment on a 1928 Velie 66 Series, especially if the car has had wheel changes, brake conversions, suspension work, or replacement hubs over the years. Even when the car still looks stock, those changes can alter which of the two primary tire sizes actually belongs on it.
A careful inspection should confirm wheel diameter, wheel condition, and clearance around fenders and steering components before choosing a tire. On a vehicle this old, it is wise to evaluate the complete rolling setup rather than assume the current tires or wheels reflect the correct combination.
What should I inspect before driving a 1928 Velie 66 Series on new tires?
Before driving a 1928 Velie 66 Series on new tires, inspect the wheels, valve hardware, and the tire mounting itself, then check that the tires are seated properly and inflated evenly. It is also smart to look over steering linkage, suspension components, and brake condition on a car from this era.
The first road use should include a cautious check for rubbing, pulling, vibration, or unusual tire behavior at low speed. A collector vehicle that has spent long periods parked may reveal unrelated mechanical issues once it returns to regular movement, so tire installation should be treated as part of a broader readiness check.
How should tires on a collector 1928 Velie 66 Series be maintained?
Tires on a collector 1928 Velie 66 Series should be inspected regularly for cracking, cuts, bulges, tread wear, and signs of slow air loss, even if the car is driven sparingly. Low annual mileage does not stop rubber from aging, and long storage periods can hide problems until the car is back on the road.
Storage conditions matter as much as mileage on a vintage vehicle. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve tire condition, while routine pressure checks and periodic wheel inspections support safer operation when the car is used again.
