The 1928 Pierce Arrow 81 Series comes from an era when premium American automobiles were built with imposing proportions, formal coachwork, and a strong emphasis on quiet, dignified road manners. For many owners today, the tire decision is closely tied to preserving that distinctly late-1920s character. This Pierce Arrow uses bias-ply fitments in two period sizes, 30X5.77 and 30x5, both tied to 7-inch wheel fitment context on this page. Those choices matter because they reflect different vintage sizing conventions rather than a modern one-size-fits-all replacement approach. Selecting the right tire starts with confirming which of the two original-style sizes belongs on the car and then matching appearance and wheel compatibility carefully.
Which Tire Size Is Right for The 1928 Pierce Arrow 81 Series
The 1928 Pierce Arrow 81 Series uses two primary tire sizes, and both are bias-ply fitments rooted in late-1920s tire practice. Because the two sizes follow different vintage sizing conventions, the first step is confirming which tire is actually on the car now and verifying the wheel setup before choosing a replacement for restoration use or road service.
30X5.77 is an antique diameter-by-section size, meaning the first number refers to an approximate 30-inch overall tire diameter and the second number refers to an approximate 5.77-inch section width. It is a bias-ply fitment that suits the period construction and visual character expected on a 1928 Pierce Arrow 81 Series. This format is especially relevant to buyers trying to stay close to original-era sizing language rather than substituting a later convention. It deserves a careful wheel and fitment check because antique sizes can look straightforward while still requiring attention to wheel design and overall compatibility.
30x5 is also an antique diameter-by-section size, with the 30 indicating approximate overall diameter and the 5 indicating approximate section width. On the 1928 Pierce Arrow 81 Series, it remains a bias-ply, restoration-oriented fitment that reflects an even earlier style of tire sizing familiar to pre-war and late-brass-era vehicles. Its beaded-edge style association makes it particularly important to evaluate with care rather than treating it like a later drop-center wheel application. Buyers considering this size should confirm the car's existing wheel type and current tire setup before moving ahead.
Sub-model fitment is straightforward here because the covered 1928 Pierce Arrow 81 Series configuration uses the same two period tire sizes. Checking the exact sub-model still matters so the replacement tire matches the car's existing wheel and vintage fitment style.

1928 Pierce Arrow 81 Series 6 Cyl.
The 1928 Pierce Arrow 81 Series 6 Cyl. uses the same pair of bias-ply vintage tire sizes found on this page, so the main question is not trim-level variation but confirming the wheel and tire arrangement already on the car. That makes selection more about correct period-style fitment, wheel compatibility, and whether the car is being prepared for show presentation or careful road use.
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
Owners of a 1928 Pierce Arrow 81 Series usually need clarity on vintage tire size meaning, wheel fitment, period-style replacement choices, and the inspections that matter before putting a large pre-war automobile back on the road.
Tire Size & Fitment
What tire size fits a 1928 Pierce Arrow 81 Series?
The 1928 Pierce Arrow 81 Series uses two primary tire sizes: 30X5.77 and 30x5. Both are bias-ply fitments, and the covered 81 Series 6 Cyl. application uses those same period sizes rather than a modern metric or alphanumeric replacement standard.
That means the first step is confirming which size is actually mounted on the car and which wheel style it uses now. On a collector car of this age, wheels, tires, and even rims may have been changed over time, so matching the replacement tire to the existing setup is more important than assuming either vintage size applies automatically.
What size rim does a 1928 Pierce Arrow 81 Series use?
The 1928 Pierce Arrow 81 Series uses a 7-inch rim diameter in the fitment covered here. That rim diameter is tied to the 30X5.77 fitment and serves as an important reference point when evaluating replacement tires for a car from this era.
Rim diameter alone is not the whole story on a 1920s luxury car. Antique tire fitment can also depend on wheel type and how the tire is intended to seat, so it is smart to inspect the existing wheel carefully before ordering a replacement. A close look at the current tire markings and wheel construction will usually resolve the fitment question.
What does 30X5.77 mean on a 1928 Pierce Arrow 81 Series?
30X5.77 is an antique diameter-by-section size. The 30 refers to the tire's approximate overall diameter in inches, and the 5.77 refers to its approximate section width, also in inches, rather than a modern wheel-diameter-based size code.
For a 1928 Pierce Arrow 81 Series owner, that means the size should be read as part of an older tire system, not compared casually with later passenger-car sizing. The practical next step is to verify the exact wheel and existing tire arrangement on the car so the replacement keeps the correct vintage fitment relationship without clearance or mounting surprises.
Choosing the Right Tire
What should I consider when choosing a 30X5.77 tire for a 1928 Pierce Arrow 81 Series?
Start with the basics: confirm that 30X5.77 is the size actually used on the car, and confirm that the wheel matches the intended application. On a 1928 Pierce Arrow 81 Series, this size is a bias-ply vintage fitment, so the decision is usually centered on preserving proper era appearance and mechanical compatibility.
A careful choice also means looking at how the car will be used. A restoration focused on period presentation may place more emphasis on original-style sizing convention, while a regularly driven collector car still needs the same attention to wheel condition, tire age, and proper mounting. With antique fitments, verifying the existing setup matters more than making assumptions from appearance alone.
How do I choose between the available 30X5.77 and 30x5 tires for a 1928 Pierce Arrow 81 Series?
The right choice depends on which of the two original-style sizes belongs on the specific car and wheel arrangement. Both 30X5.77 and 30x5 are bias-ply fitments for the 1928 Pierce Arrow 81 Series, but they represent different vintage sizing conventions and should not be treated as casual substitutes.
A good selection process starts at the wheel, not the catalog page. Inspect the tire currently mounted, read the sidewall markings, and examine the wheel construction before deciding. That approach helps preserve the intended stance and period character of the car while reducing the chance of choosing a tire that matches the numbers loosely but not the actual hardware.
What rim-fitment details matter when choosing tires for a 1928 Pierce Arrow 81 Series?
The key rim detail is making sure the wheel matches the tire's intended mounting style and diameter. A 7-inch rim diameter is part of the fitment context for this 1928 Pierce Arrow 81 Series, and antique sizes such as 30X5.77 and 30x5 demand closer checking than later standardized passenger-car sizes.
Condition matters just as much as nominal size on a car of this age. Inspect the wheels for damage, corrosion, past repairs, and any signs that the car may have been converted to a different setup years ago. Tire selection becomes much easier once the wheel itself has been positively identified and judged suitable for safe service.
Restoration & Appearance
Which tire should I choose for a period-style 1928 Pierce Arrow 81 Series?
A period-style choice for a 1928 Pierce Arrow 81 Series starts with staying within the correct primary vintage size family: 30X5.77 or 30x5, depending on the car's actual wheel and tire setup. Both are bias-ply fitments, which aligns naturally with the appearance and road character expected from a late-1920s luxury automobile.
Appearance alone should not decide the purchase on a restoration-oriented car. The strongest approach is to verify which size belongs on the specific vehicle, then compare that against historical references tied to the car if originality is especially important. That keeps the tire choice grounded in both presentation and fitment rather than style alone.
Does correct tire fitment matter for a 1928 Pierce Arrow 81 Series restoration?
Correct tire fitment matters a great deal on a 1928 Pierce Arrow 81 Series because the tire contributes heavily to the car's stance, wheel presentation, and overall period impression. Using the proper vintage size convention also helps keep the restoration visually consistent with how a late-1920s Pierce Arrow should sit.
That does not mean every surviving car will still have its original wheel arrangement intact. Restored and long-stored cars sometimes carry replacement wheels, older conversions, or mismatched tires from earlier ownership. Before choosing a new set, inspect the wheels and current tire markings closely so the restoration reflects the car's actual hardware as well as its intended era.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1928 Pierce Arrow 81 Series?
Yes, modifications can affect tire fitment on a 1928 Pierce Arrow 81 Series, especially on a vehicle that may have seen many decades of repairs, wheel swaps, or restoration work. Changes to wheels, hubs, suspension height, brake components, or body clearance can alter what fits safely even when the tire size appears period-appropriate.
That is why a visual inspection should come before any purchase. Check the actual wheel construction, current mounted size, and clearance around fenders and steering components. On antique cars, fitment problems are often caused less by the catalog size itself and more by older modifications that changed the relationship between tire, wheel, and chassis.
What should I inspect before driving a 1928 Pierce Arrow 81 Series on new tires?
Before road use, inspect the wheels, lug hardware or locking hardware as applicable, valve stems, and the overall condition of the suspension and steering. A 1928 Pierce Arrow 81 Series is a large, heavy pre-war automobile, so the tires need to be mounted on sound wheels and supported by components that are ready for use.
A short shakedown drive is smarter than a long outing right away. Watch for rubbing, unusual steering feel, vibration, and any sign of air loss after the first miles. Rechecking inflation, wheel security, and visible sidewall condition after initial use helps confirm that the new tires and the car's existing mechanical setup are working together properly.
How should 30X5.77 or 30x5 tires on a collector 1928 Pierce Arrow 81 Series be maintained?
Collector-car tires in 30X5.77 or 30x5 should be kept clean, properly inflated, and inspected regularly even if the 1928 Pierce Arrow 81 Series is driven only occasionally. Low annual mileage does not prevent aging, so sidewall cracking, flat spotting, cuts, bulges, and slow air loss all deserve attention.
Storage conditions also matter on a pre-war car. Keeping the vehicle away from prolonged sunlight, heat, moisture, and ozone sources helps protect the tires between drives, and rolling the car periodically can reduce long-term stress in one contact area. A brief inspection before each outing is a sensible habit, especially after long periods of display or storage.
