Cadillac Model A Tires
Cadillac Model A introduced the young Cadillac marque at the dawn of the American automobile industry, and the 1903 to 1904 cars belong squarely to the brass-era world of light runabouts, simple controls, and very early wheel and tire standards. That matters because tire selection for Cadillac Model A is not a modern size-reading exercise; the car uses an early diameter-by-section tire designation that can be easily misunderstood if you read it like a later passenger-car size. The first step is to verify that the car still carries the correct early wheel for its original tire format, then match the tire by construction style and sidewall appearance for the intended restoration.
Cadillac Model A Tire Size Guide
Cadillac Model A uses one distinct tire size across the 1903 to 1904 production span: 28X3. This is an antique diameter-by-section size, so the first number refers to an overall tire diameter of 28 inches and the second number refers to a 3-inch section width, rather than a modern wheel diameter reading. Available products in this size come from Universal Vintage Tire in both All White and Blackwall sidewall styles. The products in this size are made to order. A tube is required.
Cadillac Model A Tires by Year
The year listing breaks Cadillac Model A tire fitment down by production year so you can confirm the correct size for a 1903 or 1904 car. The leading number in the 28X3 size code is the tire's outside diameter, not the wheel size, so the wheel itself should be checked carefully before final selection. These early Cadillac Model A listings are best verified against original vehicle literature or a knowledgeable marque specialist.

Frequently Asked Questions
The FAQ below focuses on the early Cadillac Model A tire questions that matter most, including how to read the 28X3 size, whether tubes are required, what made-to-order means, and how to care for brass-era tires on a low-use collector car.
Size Basics & Fitment
Cadillac Model A uses one tire size across the years covered here: 28X3 for both 1903 and 1904. That makes the basic fitment straightforward at the model level, but it is still an early brass-era size that should be read differently from later numeric or metric passenger-car sizing.
The practical step is to confirm that the car still carries the correct early wheel and tire format rather than assuming any 28-inch marking refers to the wheel itself. On a brass-era restoration, original literature, surviving wheel dimensions, and the actual wheel condition all deserve a close look before a final tire choice is made.
On a Cadillac Model A, 28X3 is an antique diameter-by-section size. The 28 refers to the tire's overall outside diameter in inches, while the 3 refers to the nominal section width. It does not identify the wheel diameter the way a later 15-inch or 16-inch tire size would.
That distinction is important because many first-time brass-era buyers misread the size and end up comparing it to later tire conventions. When working with a Cadillac Model A, treat the antique size as a period designation first, then verify the actual wheel and fitment details on the car before choosing a tire for restoration or careful road use.
Cadillac Model A uses an antique size format, so the rim diameter is not stated in the 28X3 code itself. The visible size marking gives overall tire diameter and section width, which means the wheel diameter has to be confirmed separately on the actual wheel and against the product specifications for the tire being considered.
That is one of the most important checks on an early Cadillac Model A because brass-era cars are often restored, re-wheeled, or assembled from long-stored parts. Measure the wheel carefully and compare it to the intended tire's specifications rather than relying on the size code alone, especially if the car's history is uncertain.
Cadillac Model A uses an early antique-format tire and the available products are appropriate to brass-era construction, so a tube is required. That is normal for this period and should be treated as part of the complete tire fitment rather than an optional extra.
Tube fit, flap needs where applicable, and wheel condition all matter on a car as early as Cadillac Model A. Before mounting new tires, inspect the wheel for corrosion, burrs, spoke issues, and any irregularity that could damage a tube, because an otherwise correct tire can still give poor service if the wheel itself is not prepared properly.
Buying the Right Tire
A 1903 Cadillac Model A uses 28X3. Since only one size is listed for that year, the main question is not choosing between multiple listed sizes but confirming that the car still retains the proper early wheel arrangement and has not been altered during restoration or long-term ownership.
The best approach is to inspect the wheel, compare the car against period references, and make sure the tire style matches the restoration goal. On a brass-era Cadillac Model A, even a single listed size still deserves careful checking because wheel changes, reproduction parts, and mixed-era components are common in very early automobiles.
Cadillac Model A tires are available in both All White and Blackwall sidewall styles in the 28X3 size. That gives restorers a choice in presentation while staying within the available offerings for this early brass-era Cadillac.
Sidewall appearance should be chosen with the car's restoration standard in mind rather than as a cosmetic afterthought. A show-oriented Cadillac Model A may call for one look, while a historically conservative restoration may favor another, so compare the sidewall treatment to period photos, club guidance, and the overall finish of the car.
For Cadillac Model A, the available 28X3 tires are made-to-order products. That identifies them as specialty collector tires produced for a very narrow early-automobile application rather than a mass-market tire line.
The practical implication is that Cadillac Model A buyers should approach tire selection carefully and settle the fitment details before committing to a style. On a brass-era car, it also makes sense to think through sidewall preference, overall restoration goals, and wheel readiness at the same time so the tire choice supports the whole project.
Maintenance & Longevity
Cadillac Model A should be stored in a cool, dark, dry space away from direct sunlight, electric motors, welders, or other ozone-producing equipment that can age rubber prematurely. Because it is a brass-era automobile with narrow antique-format tires, clean storage conditions and stable temperatures matter more than they would on a frequently driven modern car.
If the Cadillac Model A will sit for long periods, keep the tires properly inflated, move the car occasionally to avoid prolonged flat spotting, and avoid parking on damp concrete or oil-stained surfaces. Many owners also reduce sustained load with careful support under the chassis when the car is stored for extended stretches.
Tires on a Cadillac Model A should be inspected before every drive and more thoroughly at regular intervals even if the car sees only occasional use. On a brass-era tire, sidewall cracking, tread separation, tube issues, wheel condition, and bead-area damage can become serious long before tread wear looks significant.
A careful inspection routine is part of operating a very early car responsibly. Check inflation, look for any change in shape or surface condition, and have a specialist review the tires and wheels periodically if the Cadillac Model A is driven beyond simple display movement or short exhibition runs.
Cadillac Model A tires should be replaced when age, cracking, hardening, distortion, or any structural concern appears, even if the tread still looks usable. On a brass-era car, low mileage does not prevent rubber aging, and time often matters more than wear in deciding when a tire has reached the end of safe service.
That rule is especially important for collector cars that spend years in storage and then return to use only occasionally. A Cadillac Model A intended for tours, demonstrations, or even short road movement deserves fresh, carefully inspected tires rather than relying on old rubber that merely looks acceptable from a distance.
Restoration & Authenticity
Cadillac Model A uses the 28X3 size in the years covered here, and the available replacement style is a ribbed tread offering. That gives restorers a strong starting point for matching the car to an early brass-era tire format without jumping ahead to later balloon, alphanumeric, or metric sizing conventions.
For a highly exact restoration, the final word should come from period Cadillac literature, surviving original examples, and marque-club research rather than from size alone. Early cars like Cadillac Model A can appear simple, but details such as sidewall presentation and tread style can matter in judging and historically focused restorations.
Correct tire fitment can absolutely affect how a Cadillac Model A is viewed in restoration judging and by knowledgeable collectors. Brass-era cars are often evaluated as complete historical objects, so tire size, appearance, and overall appropriateness can influence authenticity just as much as paint, trim, or hardware details.
For that reason, Cadillac Model A owners should treat tire choice as part of the restoration plan rather than as a final cosmetic step. Marque clubs, period photographs, and established early-car judges can help determine whether a particular sidewall look and tread style support the kind of restoration standard the owner is trying to achieve.
Cadillac Model A tires are available in All White and Blackwall sidewall styles. Either may suit a restoration depending on the presentation goal, since very early cars often require owners to balance historical interpretation, surviving reference material, and the visual character of the finished automobile.
The right choice depends on whether the Cadillac Model A is being restored for strict period appearance, club judging, touring, or a more display-oriented finish. Comparing the car against period images and marque guidance is worthwhile, because sidewall color on a brass-era automobile changes the overall look more dramatically than many buyers expect.
Safety & Road Use
A Cadillac Model A is a brass-era automobile and should be treated accordingly, even when fitted with newly made tires in the correct size. Public-road use calls for caution because the car's braking, steering, lighting, and overall mechanical design belong to a much earlier motoring environment than modern traffic conditions.
For most owners, the sensible use pattern is limited, low-speed operation such as exhibitions, parade movement, or short controlled drives after a thorough mechanical review. Tire condition is only one part of the safety picture on a Cadillac Model A, so the entire car should be evaluated before any regular road movement is attempted.
Before driving a Cadillac Model A, inspect tire inflation, visible sidewall and tread condition, wheel integrity, tube-related issues, and any sign of shifting or damage at the bead area. Because the car uses early antique-format tires, those checks should be paired with a broader review of steering response, brake function, lubrication, and general chassis condition.
A brass-era Cadillac Model A rewards careful preparation more than spontaneous use. Even for a very short drive, make sure the tires match the wheels correctly, the car rolls freely, and there are no age-related faults that could turn a simple outing into a difficult roadside problem.
Cadillac Model A should be driven at very modest speeds that respect the limitations of an early brass-era car and its period tire format. Even when the tire size is correct, the vehicle's original design belongs to an era of low-speed motoring, simple roads, and far lighter traffic demands than drivers face today.
In practice, Cadillac Model A is best suited to gentle operation for shows, demonstrations, and short local movement rather than sustained road speed. A conservative pace reduces stress on the tires, tubes, wheels, and chassis, and it better matches the way an early Cadillac should be used if preservation is the goal.
