The 1991 Cadillac Allante reflects Cadillac’s attempt to blend European-influenced road manners with American luxury in a two-seat personal convertible. By this point in the model’s run, the Allante had developed into a distinct grand-touring car, and tire choice plays a major role in preserving that character. The 1991 Cadillac Allante uses a 225/55R16 radial tire on a 16-inch rim, giving owners one clear primary fitment to start from. Available choices stay within that modern metric radial size and center on BFGoodrich g-Force series blackwall tires. The real decision is matching that correct size to the car’s intended use, wheel setup, and preferred road-going character.
Which Tire Size Is Right for The 1991 Cadillac Allante
The 1991 Cadillac Allante uses one primary tire size: 225/55R16. It is a radial tire fitment for a 16-inch rim, and that same size is shared by the Base and Value Leader sub-models. Since the fitment itself is straightforward, the main decision becomes choosing the right tire within that size by looking at tire series, road-use intent, and wheel compatibility.
A 225/55R16 size uses a 225-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 1991 Cadillac Allante, this modern metric radial format suits the car’s later-era luxury-sport character and keeps fitment aligned with its original wheel diameter. In this size, available choices include BFGoodrich blackwall tires from the g-Force Sport Comp 2 and g-Force Comp 2 AS series. The practical comparison is less about size selection and more about choosing the tire that best matches the car’s driving use while staying within the correct rim-width range.
Tire fitment is straightforward across the covered 1991 Cadillac Allante sub-models. Both sub-models use the same 225/55R16 radial size, so the key step is confirming the car still has the correct 16-inch wheel setup before comparing tire choices.

Tire Size & Fitment
What tire size fits a 1991 Cadillac Allante?
The 1991 Cadillac Allante uses a 225/55R16 radial tire. That is the primary tire size for this model and it is used on a 16-inch rim. Both the Base and Value Leader sub-models use the same size, so the fitment question is simpler here than on vehicles that vary by trim or wheel package.
The next step is making sure the car still has the correct wheel diameter and a wheel width that suits the tire. A 225/55R16 tire should also be checked against the actual wheel and vehicle setup if the Allante has had aftermarket wheels, suspension changes, or long-term storage that could affect fitment condition.
What size rim does a 1991 Cadillac Allante use?
The 1991 Cadillac Allante uses a 16-inch rim with its 225/55R16 tire size. Available tires in this size are built for that same 16-inch wheel diameter, and the products offered here show a rim-width compatibility range of 6.0 to 8.0 inches.
Wheel diameter should be confirmed before ordering tires, especially on a collector-era car that may have seen wheel changes over the years. Width matters too, because a 16-inch wheel can still be too narrow or too wide for the intended tire. Verifying both dimensions helps avoid clearance, mounting, and handling issues.
Do all 1991 Cadillac Allante sub-models use the same tire size?
Yes. The covered 1991 Cadillac Allante sub-models use the same 225/55R16 radial tire size. That includes the Base and the Value Leader, so there is no split in primary tire size among those versions.
That consistency makes the search easier, but it is still worth checking the actual wheels on the car before selecting tires. A previous owner may have changed wheel width or diameter, and even when the nominal size remains correct, wheel condition, suspension wear, and fender clearance should still be considered on an older luxury road car.
Choosing the Right Tire
What should I consider when choosing a 225/55R16 tire for a 1991 Cadillac Allante?
Start with the correct size, which is 225/55R16, and make sure the tire matches the car’s 16-inch wheel diameter. From there, compare the available radial tire series, confirm that the wheel width falls within the tire’s approved range, and think about whether the Allante will be used for occasional cruising, fair-weather touring, or broader street driving.
Construction is not the variable here because the primary fitment is already radial, so the finer points are series choice, wheel compatibility, and overall vehicle condition. It also helps to inspect the suspension, steering components, and alignment, since a fresh set of tires will show problems quickly if the chassis setup is no longer in good order.
What sidewall styles are available for 1991 Cadillac Allante tires?
The available 225/55R16 tires for the 1991 Cadillac Allante use a blackwall sidewall style. That keeps the appearance clean and appropriately modern for a late-run Allante, especially compared with the period presentations more often associated with earlier collector vehicles.
Since sidewall styling does not vary among the current options, the real comparison shifts to tire series and intended driving use. Owners focused on preserving the Allante’s original visual balance should still confirm wheel finish, ride height, and overall stance, because those details affect appearance just as much as the sidewall itself.
What tire series are available for the 1991 Cadillac Allante?
Two BFGoodrich tire series are available in the correct 225/55R16 size for the 1991 Cadillac Allante: g-Force Sport Comp 2 and g-Force Comp 2 AS. Both are radial blackwall tires built for a 16-inch rim and both fall within the same general fitment envelope for wheel width.
Choosing between them comes down to how the car is driven and which series better suits the owner’s priorities. The important point is to stay with the proper size and confirm wheel condition before mounting new tires, since even the right size can feel wrong if the wheel, alignment, or suspension setup is not sorted.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Cadillac Allante?
A period-style approach for a 1991 Cadillac Allante starts with the correct 225/55R16 size and a radial construction, since that is the vehicle’s primary fitment. The available BFGoodrich blackwall options keep the presentation in line with the Allante’s late-model luxury-sport character rather than pushing it toward an earlier vintage look.
Appearance-focused buyers should pay close attention to overall stance, wheel finish, and whether the car still rides at its intended height. Exact originality claims are best confirmed through marque-specific references and vehicle history, but staying with the proper size and sidewall style is a strong starting point for a tasteful restoration-oriented presentation.
Does correct tire fitment matter for a 1991 Cadillac Allante restoration?
Yes, correct tire fitment matters on a 1991 Cadillac Allante restoration because the tire size influences both the car’s visual balance and the way it presents on its 16-inch wheels. Using the proper 225/55R16 radial size helps maintain the proportions expected of an Allante from this period.
Restoration-minded owners should think beyond the tire code alone and check the actual wheel dimensions, ride height, and surrounding chassis condition. Tires that are technically close in concept can still change the look if the profile, sidewall treatment, or wheel setup is off, so careful fitment verification is part of getting the car right.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Cadillac Allante?
Yes. Modifications can affect tire fitment on a 1991 Cadillac Allante even when the intended tire size remains 225/55R16. Changes to wheel width, wheel offset, suspension height, springs, or steering components can alter clearance and change how the tire sits within the wheel opening.
A modified Allante should be checked carefully before new tires are installed. Confirm the actual wheel diameter and width, then inspect for fender, inner wheelhouse, and steering-clearance issues through the full range of motion. That is especially important on cars that have been lowered, fitted with aftermarket wheels, or rebuilt with non-stock suspension parts.
What should I inspect before driving a 1991 Cadillac Allante on new tires?
Before putting a 1991 Cadillac Allante back on the road with new tires, inspect the wheels for damage, verify proper inflation, and look over the suspension and steering for worn components. Alignment condition matters as well, because even a correct 225/55R16 tire can wear quickly or behave poorly if the chassis geometry is off.
It also helps to check brake condition, wheel-bearing smoothness, and any signs of rubbing at the inner fender or suspension points. On a car that may have seen limited seasonal use, a short and careful test drive is worthwhile to confirm that the tires seat properly, the car tracks straight, and no vibration appears at speed.
How should 225/55R16 tires on a collector 1991 Cadillac Allante be maintained?
225/55R16 tires on a collector 1991 Cadillac Allante should be kept at the correct pressure for the vehicle setup, inspected regularly for cracking, cuts, bulges, and uneven wear, and protected from long periods of harsh sunlight or ozone exposure. Low-mileage collector cars can age tires out long before they wear them out.
Routine checks are especially important if the car spends time parked between drives. Rolling the vehicle periodically, storing it on a clean surface, and watching for slow air loss can help preserve the tires and the way the Allante drives. Any signs of vibration, flat-spotting, or visible deterioration deserve attention before longer trips.
