Cadillac Allante Tires

Cadillac Allante uses three tire sizes across its 1987-1993 production run. The 1987 and 1988 Cadillac Allante uses 225/60R15 on a 15-inch rim. The 1989 through 1992 Cadillac Allante uses 225/55R16 on a 16-inch rim, and the 1993 Cadillac Allante uses 225/60R16 on a 16-inch rim.

The practical takeaway is that year matters immediately on a Cadillac Allante, because the wheel diameter changed after 1988 and the final year uses a different 16-inch profile than 1989-1992. Start with the model year, then confirm the wheel diameter stamped on the rim or measured on the wheel itself before selecting a tire.

On a Cadillac Allante, 225/60R15 is a modern metric radial size. The 225 is the nominal section width in millimeters, the 60 is the aspect ratio, meaning the sidewall height is 60 percent of the section width, the R means radial construction, and the 15 is the required rim diameter in inches. That size belongs to 1987-1988 Cadillac Allante fitment.

Understanding the code helps prevent one of the most common Allante mistakes: assuming all 225-section tires are interchangeable. They are not. A 225/60R15 requires a 15-inch wheel, while later Allante sizes require 16-inch wheels, so matching the final number in the size code to the actual rim is essential.

Cadillac Allante used two rim diameters during production. The 1987-1988 Cadillac Allante uses 15-inch rims with 225/60R15 tires, while 1989-1993 Cadillac Allante models use 16-inch rims. Within the 16-inch years, 1989-1992 uses 225/55R16 and 1993 uses 225/60R16.

That wheel change is the first thing to verify on any Cadillac Allante, especially on a car that may have had wheels changed over time. If the car is an early model, confirm it still has 15-inch wheels. If it is a later car, make sure you distinguish between the 1989-1992 profile and the 1993 final-year size.

The correct size for a Cadillac Allante is tied first to the model year and then to the wheel diameter on the actual car. A 1987-1988 Cadillac Allante uses 225/60R15, a 1989-1992 Cadillac Allante uses 225/55R16, and a 1993 Cadillac Allante uses 225/60R16. Those are three distinct fitments, not interchangeable substitutes.

Use the year listing as the starting point, then inspect the tire sidewall already on the car and verify the rim diameter on the wheel itself. That matters most on cars that have been restored, personalized, or stored for long periods, because a Cadillac Allante may no longer wear its original wheel-and-tire combination.

Cadillac Allante tires are available in several sidewall styles depending on size. 225/60R15 options include blackwall, wide whitewall, redline, and RWL. 225/55R16 options in this range are blackwall, while 225/60R16 offers blackwall, redline, pin white stripe, wide whitewall, narrow whitewall, and raised yellow letter styles.

Sidewall choice affects the visual character of a Cadillac Allante more than fitment, so it is usually the final decision after year and wheel size are confirmed. Owners pursuing a factory-like late-1980s or early-1990s look often stay with blackwall, while whitewall, stripe, or lettered options can shift the car toward a more personalized period appearance.

The brands represented for Cadillac Allante tire sizes here are Goodyear, BFGoodrich, Avon, and Travelstar. Brand availability varies by size. The broadest selection appears in 225/60R15 and 225/60R16, while 225/55R16 is represented by BFGoodrich options in this range.

Brand selection is easiest once the correct year-specific size is settled. After that, compare sidewall style, intended use, and the general personality you want for the car. A Cadillac Allante used for touring, local events, or a more performance-flavored presentation may lead you toward different choices even within the same size.

Cadillac Allante fitments here include several radial tire series: Goodyear Eagle Gatorback, BFGoodrich Silvertown Radial, BFGoodrich Radial T/A, Avon CR6ZZ, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Comp 2 AS, Goodyear Eagle NASCAR, and Travelstar UN106. These differ primarily in visual style, intended character, and sidewall treatment rather than basic construction, since all are radial tires.

The practical difference is choosing between a more period-styled appearance and a more modern performance-oriented presentation. A Silvertown Radial with whitewall, redline, or pin stripe will suit a more traditional look, while Gatorback, g-Force, CR6ZZ, or lettered performance styles can better match an owner who wants a sportier visual statement on a Cadillac Allante.

A Cadillac Allante should be stored on clean, properly inflated tires in a cool, dry, dark space away from direct sunlight, ozone sources, and major temperature swings. Electric motors, welders, furnaces, and similar equipment can accelerate rubber aging. If the car will sit for long periods, move it occasionally so one section of the tire does not carry the load continuously.

Collector cars like Cadillac Allante often age their tires by time and environment rather than mileage. Keeping the car out of UV exposure and maintaining proper inflation will do more for tire life than simply driving it less. If long-term storage is expected, regular visual checks for flat spotting, sidewall cracking, and pressure loss are worthwhile.

Tires on a Cadillac Allante should be inspected before any meaningful drive and at regular intervals even when the car is mostly parked. Look for cracking, bulges, uneven wear, tread separation signs, punctures, and air loss. On a low-mileage collector car, those condition checks matter more than tread depth alone.

A practical routine is to inspect the tires every month during storage and again before any highway or event use. Cadillac Allante owners should also pay attention to tire age, because a roadster that sees limited annual mileage can still be riding on tires that appear attractive but have already aged beyond their safest service window.

Cadillac Allante tires should be replaced when age, cracking, hardening, vibration, sidewall damage, or other condition issues appear, even if the tread still looks deep. Collector-car tires often wear out chemically before they wear out mechanically. A tire can look usable at a glance while no longer offering the road manners expected from a grand-touring Cadillac.

The best approach is to treat age and condition as seriously as tread. If a Cadillac Allante has been stored for years, have the tires evaluated carefully before resuming regular road use. Replacement is especially wise when there is any doubt about age history, storage conditions, or changes in ride quality at speed.

Cadillac Allante fitment in this range is year-specific rather than one-size-fits-all. Early 1987-1988 cars use 225/60R15, 1989-1992 cars use 225/55R16, and 1993 cars use 225/60R16. Available series include period-flavored options such as Goodyear Eagle Gatorback and BFGoodrich Silvertown Radial alongside other radial choices.

For restoration work, the important point is matching the tire size to the exact year before worrying about brand or sidewall cosmetics. Once that is settled, period appearance becomes the next decision. Original photos, surviving delivery literature, and Cadillac marque references are the best guides when a factory-correct presentation is the goal.

Correct tire fitment can affect both presentation and judging on a Cadillac Allante because wheel diameter, tire profile, and sidewall style all change the car’s stance and visual period character. A 1987-1988 Cadillac Allante on 15-inch tires presents differently from a later 16-inch car, and a 1993 Cadillac Allante has its own distinct sidewall profile as well.

For a judged or carefully restored Cadillac Allante, getting the year-correct size right is usually the first authenticity step. After that, choose a sidewall style that matches the era and the restoration objective. Marque clubs, period photography, and event judging standards are the best references when authenticity matters more than personal preference.

Cadillac Allante tires in these sizes are available in blackwall, wide whitewall, redline, RWL, pin white stripe, narrow whitewall, and raised yellow letter styles, though not every style is available in every size. Blackwall is the most restrained late-1980s and early-1990s presentation in this group, while whitewall and stripe options create a more personalized or upscale custom look.

The correct restoration choice depends on whether the goal is factory-like visual restraint or a period-personalized appearance. Confirm the proper size for the exact Cadillac Allante year first, then narrow the sidewall treatment to match the car’s intended presentation. Sidewall style will not correct a wrong fitment, but it can strongly influence authenticity once the size is right.

The listed Cadillac Allante tires are radial designs intended for road use when they are the correct size for the car, properly mounted on the correct rim diameter, inflated correctly, and in sound condition. Safety depends on the complete condition of the tire, wheel, suspension, and braking system rather than the size designation alone.

Before regular road use, make sure the Cadillac Allante is wearing the exact year-appropriate size and that the tires are free from age-related deterioration. A later 16-inch tire cannot safely substitute for an early 15-inch wheel, and an early 15-inch fitment cannot be forced onto a later 16-inch application. Fitment accuracy is the foundation of safe road use.

Before driving a Cadillac Allante, check tire pressure, visible sidewall and tread condition, wheel security, and any signs of rubbing, uneven wear, vibration, or air loss. Also confirm that the tire size matches the car’s year and wheel diameter: 225/60R15 for 1987-1988, 225/55R16 for 1989-1992, and 225/60R16 for 1993.

That quick inspection is especially important on a collector car that may sit for weeks or months between drives. A Cadillac Allante can look ready for the road while still carrying aged tires, low pressure, or a mismatched set from a previous owner. A careful pre-drive check helps catch those issues before they become road problems.

A Cadillac Allante should only be driven at speeds appropriate to the tire actually fitted, the tire’s present condition, and the overall mechanical state of the car. The fitments listed here are radial road tires rather than brass-era or pre-war designs, but age and storage history still matter greatly on a collector vehicle from this period.

The practical rule is to avoid assuming that an older-looking but unworn tire is ready for sustained high-speed use. If a Cadillac Allante has recently returned to service after storage, build confidence gradually with inspection, careful test driving, and fresh pressure checks. Stable behavior, correct fitment, and confirmed tire condition should come before extended highway speeds.
