The 1962 Cadillac Commercial Series was built for specialized coachbuilt duty, serving in professional applications where Cadillac ride quality and presence mattered as much as durability. Vehicles in this class often carry a very different visual and functional character than a standard passenger car, so tire choice has to respect both the vehicle’s proportions and its intended use. The primary fitment is a 890-15 bias-ply tire on a 15-inch rim. Available options include traditional wide whitewall treatments as well as a blackwall bias-ply choice. For a restoration-minded owner, the real decision is balancing period-style appearance, load-carrying needs, and careful wheel compatibility before the vehicle returns to road use.
Which Tire Size Is Right for The 1962 Cadillac Commercial Series
The 1962 Cadillac Commercial Series uses one primary tire size: 890-15. This is a numeric bias-ply tire for a 15-inch rim, and the same size applies to the covered Base sub-model. With size settled, the main choice becomes how closely the tire should match a traditional commercial-series presentation, including sidewall style, brand, tire series, and wheel-width compatibility.
890-15 is a vintage numeric bias-ply size in which the leading number refers to the tire’s nominal section width, about 8.90 inches, and the final number identifies the 15-inch rim diameter. On a 1962 Cadillac Commercial Series, that bias-ply construction suits the vehicle’s period character and the tall, substantial look expected on a professional Cadillac chassis. Available choices include Firestone wide whitewall versions in the Firestone Classic Bias Ply series and an Avon blackwall in the Turbospeed Mk4 series. The right selection depends on whether the goal is a more formal restoration-oriented appearance or a simpler blackwall presentation, along with confirming the wheel matches the tire’s intended fitment range.
Tire fitment is straightforward on the 1962 Cadillac Commercial Series. The covered sub-model uses the same 890-15 bias-ply size, so the focus shifts from identifying different fitments to choosing the right tire style and verifying the wheel setup on the vehicle.

1962 Cadillac Commercial Series Base
The 1962 Cadillac Commercial Series Base uses the 890-15 bias-ply tire size on a 15-inch rim. That makes tire selection more about choosing the right period-style look, such as wide whitewall or blackwall, and confirming the wheel and overall vehicle setup are still appropriate for that size.
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 1962 Cadillac Commercial Series?
The 1962 Cadillac Commercial Series uses a 890-15 tire size. This is a vintage numeric bias-ply fitment mounted on a 15-inch rim, and it is the primary size used for the covered vehicle configuration, including the Base sub-model.
That means the first step is not choosing between multiple primary sizes, but confirming that the vehicle still has the correct 15-inch wheels and enough room for the proper commercial-series tire. Once that is established, the real choice becomes selecting the right bias-ply option by sidewall appearance, brand, tire series, and wheel compatibility.
What size rim does a 1962 Cadillac Commercial Series use?
The 1962 Cadillac Commercial Series uses a 15-inch rim with its 890-15 tire fitment. Product coverage for this size includes 15-inch applications, and Firestone options in this size are built around a 6.50 to 7.00 inch rim-width range.
Rim diameter needs to be verified before any tire is selected, especially on older commercial vehicles that may have seen wheel changes over time. Wheel width matters too, since a tire may share the correct 15-inch diameter but still need a suitable rim width to maintain proper shape, load support, and clearance.
What does 890-15 mean on a 1962 Cadillac Commercial Series?
On a 1962 Cadillac Commercial Series, 890-15 is a vintage numeric bias-ply size. The 890 refers to the tire’s nominal section width, approximately 8.90 inches, while the 15 indicates the rim diameter in inches.
This older sizing format reads differently from modern metric radial sizes, so it helps to interpret it before comparing products. For this Cadillac, the size points you toward a traditional bias-ply tire with the proportions expected on a coachbuilt commercial chassis, then lets you compare whitewall versus blackwall styling and wheel-width suitability within that correct size.
Choosing the Right Tire
What should I consider when choosing a 890-15 tire for a 1962 Cadillac Commercial Series?
Start with the correct size and construction: the 1962 Cadillac Commercial Series uses a 890-15 bias-ply tire on a 15-inch rim. After that, compare sidewall presentation, brand, tire series, maximum load figures, and the wheel dimensions the tire is intended to work with.
A commercial Cadillac often looks very different depending on whether it wears a wide whitewall or a blackwall, so appearance may matter almost as much as fitment. It also helps to inspect the actual wheels on the vehicle, since an older professional car may have had replacements over the years that affect how well a given 890-15 option suits it.
What sidewall styles are available for 1962 Cadillac Commercial Series tires?
The available 890-15 tires for a 1962 Cadillac Commercial Series include both wide whitewall and blackwall sidewall styles. Firestone offers wide whitewall versions, while Avon offers a blackwall option in the same general size family.
That gives the owner two very different visual directions. A wide whitewall leans toward a formal, restoration-oriented presentation that suits many period Cadillacs, while a blackwall creates a more restrained commercial look. The best choice depends on the vehicle’s intended presentation, along with confirming that the selected tire also matches the wheel and service needs of the car.
What brands offer tires for the 1962 Cadillac Commercial Series?
Firestone and Avon both offer tires for the 1962 Cadillac Commercial Series in the 890-15 size range. Firestone options appear in the Firestone Classic Bias Ply series, while Avon offers the Turbospeed Mk4 as a blackwall bias-ply alternative.
Brand choice should be treated as one part of a broader selection process rather than the only decision. It makes sense to compare the appearance each tire creates, whether the sidewall treatment suits the vehicle, and whether the wheel dimensions and load-related specifications line up with how the Cadillac will actually be used.
Restoration & Appearance
Which tire should I choose for a period-style 1962 Cadillac Commercial Series?
For a period-style 1962 Cadillac Commercial Series, the proper starting point is the 890-15 bias-ply tire size on a 15-inch rim. Within that size, the visual character changes meaningfully between Firestone wide whitewall options and the Avon blackwall offering.
The right choice depends on the vehicle’s restoration direction and how closely the finished presentation should reflect a formal professional-car look. When exact historical appearance matters, it is wise to compare the vehicle against marque references, coachbuilder history, period photos, or club guidance rather than assuming every tire style sold in the correct size matches every application.
How does tire construction affect the appearance of a restored 1962 Cadillac Commercial Series?
Tire construction matters because the 1962 Cadillac Commercial Series is built around a bias-ply fitment, and that construction contributes to the tall, traditional profile expected on an early-1960s professional Cadillac. In this application, the available tires stay within that period-style bias-ply presentation.
Appearance is shaped not only by size, but also by sidewall treatment and overall tire character. A wide whitewall gives the vehicle a more formal, ceremonial presence, while a blackwall can look more restrained and service-oriented. For a restoration, keeping the correct size and general construction style usually preserves the visual balance better than focusing on brand alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1962 Cadillac Commercial Series?
Yes, modifications can affect tire fitment on a 1962 Cadillac Commercial Series even when the tire size remains 890-15. Changes to wheels, suspension height, brake components, or body clearances can alter how a bias-ply tire sits and moves within the vehicle’s available space.
That is especially important on older commercial Cadillacs because many have had long service lives and may no longer be exactly as built. A replacement tire should be checked against actual wheel diameter and width, plus steering and fender clearance, rather than assuming the vehicle still carries its original wheel and suspension setup.
What should I inspect before driving a 1962 Cadillac Commercial Series on new tires?
Before driving a 1962 Cadillac Commercial Series on new tires, inspect the wheels for the correct 15-inch diameter, check that rim condition is sound, and make sure valve stems, mounting surfaces, and overall wheel integrity are in good order. Tire pressure should also be set appropriately for the tire and vehicle use.
The vehicle itself deserves just as much attention. Look at steering play, suspension wear, brake condition, and any signs of rubbing at the fenders or chassis. On a collector or professional car that sees limited use, it also helps to recheck inflation and visual condition after the first few drives to catch settling or clearance issues early.
How should 890-15 tires on a collector 1962 Cadillac Commercial Series be maintained?
890-15 tires on a collector 1962 Cadillac Commercial Series should be maintained with regular pressure checks, routine visual inspections, and clean storage conditions. Watch for sidewall cracking, bulges, cuts, flat spotting from long periods of inactivity, and any signs of uneven wear once the vehicle is back in service.
Collector vehicles often age their tires differently than daily drivers because long storage periods can be harder on rubber than steady use. Keeping the Cadillac away from prolonged sunlight, heat, moisture, and ozone sources helps preserve the tires, and occasional movement or careful repositioning can reduce standing stress on one section of the tread.
