The 1967 Cadillac Commercial Series sits in a very specialized corner of Cadillac history, built for professional use where long wheelbases, substantial coachwork, and dignified road presence mattered as much as durability. Vehicles in this class are often restored with close attention to stance and sidewall appearance because the tire has such a visible effect on the finished look. The 1967 Cadillac Commercial Series uses a 890-15 bias-ply tire on a 15-inch rim. Within that size, choices include wide whitewall and blackwall presentations from Firestone and Avon. The right selection comes down to the balance between restoration-oriented appearance, intended road use, and careful wheel compatibility.
Which Tire Size Is Right for The 1967 Cadillac Commercial Series
The 1967 Cadillac Commercial Series uses one primary tire size: 890-15. It is a bias-ply fitment for a 15-inch rim, and the covered Base sub-model uses the same size, so the key decision is not which size fits but which version of that size best suits the vehicle's appearance, wheel setup, and intended use.
In numeric bias-ply sizing, the 890 portion represents a nominal section width of about 8.90 inches, while the 15 identifies the rim diameter in inches. On the 1967 Cadillac Commercial Series, this is a bias-ply fitment that matches the substantial, traditional tire profile associated with large professional vehicles of the period. Available choices include Firestone and Avon offerings, with both wide whitewall and blackwall sidewall styles represented across Firestone Classic Bias Ply and Turbospeed Mk4 series. For many owners, the real decision is whether the vehicle calls for a restoration-oriented whitewall presentation or a more understated blackwall look.
Fitment is straightforward across the covered 1967 Cadillac Commercial Series sub-models. The Base model uses the same 890-15 bias-ply size, so the focus shifts from size differences to sidewall style, tire series, and wheel compatibility.

1967 Cadillac Commercial Series Base
The 1967 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 visual presentation and product characteristics than sorting through multiple fitment sizes.
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 1967 Cadillac Commercial Series?
The 1967 Cadillac Commercial Series uses a 890-15 tire size. This is a numeric bias-ply size mounted on a 15-inch rim, and the covered Base sub-model uses that same fitment.
That means the main choice is not between multiple primary sizes, but between different 890-15 tires with different sidewall treatments and product characteristics. Before selecting one, confirm that the vehicle still has the correct 15-inch wheels and has not been altered with aftermarket wheels or coachwork-related changes that could affect clearance.
What size rim does a 1967 Cadillac Commercial Series use?
The 1967 Cadillac Commercial Series uses a 15-inch rim with its 890-15 tire size. Product options in this fitment are built around that 15-inch rim diameter, and some 890-15 tires include rim-width guidance in the 6.50 to 7.00 inch range.
Rim diameter is the first thing to confirm before any replacement, especially on specialty or restored commercial vehicles. A tire can share the correct size code yet still deserve a closer look at wheel width, bead-seat condition, and overall wheel integrity if the vehicle has been stored for long periods or rebuilt over time.
Does the 1967 Cadillac Commercial Series Base use the same tire size?
Yes. The 1967 Cadillac Commercial Series Base uses the same 890-15 bias-ply tire size as the overall model fitment. There is no alternate primary size shown for the covered Base configuration.
That keeps fitment simple, but it does not eliminate the need to inspect the actual wheel and vehicle setup. A long-wheelbase professional car may have gone through restoration, wheel replacement, or extended storage, so it is still worth confirming rim diameter, wheel width, and the overall condition of the tire and wheel assembly before road use.
Choosing the Right Tire
What should I consider when choosing a 890-15 tire for a 1967 Cadillac Commercial Series?
Start with the correct 890-15 size and the fact that this application is bias-ply. From there, compare sidewall appearance, tire series, rim-width guidance where stated, maximum load figures, and the overall presentation you want from the vehicle.
A Commercial Series Cadillac often places more visual emphasis on the tire than a smaller passenger car, so whitewall width can change the look substantially. It also helps to match the tire choice to how the vehicle will be used, whether that means restoration display, occasional road use, or a more understated blackwall presentation.
What sidewall styles are available for 1967 Cadillac Commercial Series tires?
Available 890-15 tires for the 1967 Cadillac Commercial Series include wide whitewall and blackwall sidewall styles. Firestone options are offered with 3.00-inch and 5.00-inch whitewalls, while Avon offers a blackwall version in the same overall fitment family.
That gives the owner a meaningful appearance choice without changing the basic tire size. A wide whitewall tends to suit a more formal, restoration-oriented presentation, while a blackwall creates a more restrained look. The best choice depends on how the vehicle is being restored, shown, or driven rather than on size alone.
What brands offer tires for the 1967 Cadillac Commercial Series?
Firestone and Avon both offer 890-15 tires for the 1967 Cadillac Commercial Series. The available series include Firestone Classic Bias Ply and Avon Turbospeed Mk4, giving buyers more than one way to approach the correct size.
Brand choice should be weighed alongside sidewall style, series character, and wheel compatibility rather than treated as the only decision. On a large professional vehicle, visual style matters, but so do practical details such as the tire's stated load figure, any rim-width guidance, and how closely the finished look matches the intended presentation of the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Cadillac Commercial Series?
A period-style approach starts with the correct 890-15 bias-ply size, since that preserves the original-era sizing format and tire construction style associated with the 1967 Cadillac Commercial Series. From there, the visual choice centers on whether the vehicle looks right with a wide whitewall or a blackwall presentation.
Many restorations of formal commercial Cadillacs place strong emphasis on sidewall appearance because the tire is so visible against the body's scale and trim. If exact originality matters, compare the vehicle against marque references, coachbuilder history, and period photography before settling on a specific whitewall treatment or brand.
How does tire construction affect the appearance of a restored 1967 Cadillac Commercial Series?
On the 1967 Cadillac Commercial Series, the primary fitment is bias-ply, and that construction plays a major role in the vehicle's visual character. The sidewall shape and overall stance of a bias-ply tire help maintain the traditional presentation expected on a large, coachbuilt Cadillac commercial chassis.
Appearance is only part of the decision, but it is an important one on a restoration-minded vehicle. Even within the correct 890-15 size, details such as whitewall width and blackwall versus whitewall presentation can noticeably change the finished look, so tire choice should support the overall restoration theme rather than simply fill the wheel opening.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Cadillac Commercial Series?
Yes. Even though the 1967 Cadillac Commercial Series uses a 890-15 tire on a 15-inch rim, modifications can affect how that fitment works in practice. Changes to wheel width, wheel offset, suspension height, or bodywork can alter clearance and overall tire behavior.
That matters even more on a specialty commercial vehicle because coachbuilt bodies and restoration work can introduce small differences that do not appear on paper. Any time the vehicle has aftermarket wheels, suspension changes, or body modifications, inspect steering clearance, fender clearance, and wheel-to-tire compatibility before mounting new tires.
What should I inspect before driving a 1967 Cadillac Commercial Series on new tires?
Begin with the wheels, lug hardware, valve stems, and overall tire installation, then check inflation, visible clearance, and the condition of suspension and steering components. On a vehicle like a 1967 Cadillac Commercial Series, it is also wise to inspect for sidewall contact under turning and compression.
Collector and professional vehicles often spend long periods parked, so roadworthiness depends on more than fresh rubber alone. A careful pre-drive check should include brake condition, signs of air loss, unusual bulges or cuts, and any age-related issues elsewhere in the chassis that could affect safe, stable operation on the road.
How should 890-15 tires on a collector 1967 Cadillac Commercial Series be maintained?
Maintain 890-15 tires on a collector 1967 Cadillac Commercial Series with regular pressure checks, routine visual inspections, and careful attention to age and storage conditions. Even low-mile vehicles need monitoring for cracking, flat spotting, sidewall damage, tread wear, and signs of air loss.
Storage environment matters because heat, sunlight, moisture, and nearby ozone sources can shorten tire life on seldom-driven vehicles. Moving the car periodically, keeping the tires properly inflated, and checking them before each outing helps preserve both appearance and road manners, especially on a large professional chassis that places steady demand on its tires.
