The 1991 Cadillac Brougham came at the end of the traditional full-size Cadillac era, carrying the long-wheelbase, rear-wheel-drive luxury sedan formula that many collectors still associate with classic American comfort. Its upright styling and formal road presence make tire appearance almost as important as tire fitment. This car uses a 225/75R15 radial on a 15-inch rim, so the core decision is less about multiple sizes and more about choosing the right whitewall look within the correct fitment. Available choices include narrow and wide whitewall treatments across several radial lines and brands. For a road-driven or restoration-minded Brougham, matching size, sidewall style, and wheel compatibility matters just as much as maintaining the car itself.
Which Tire Size Is Right for The 1991 Cadillac Brougham
The 1991 Cadillac Brougham uses one primary tire size: 225/75R15, and it is a radial fitment for a 15-inch rim. Both the Base and d'Elegance share that same size, so the main choice is not between different fitments but between whitewall styles, tire series, brand preferences, and the wheel-width compatibility of the tire you select.
225/75R15 is a metric radial size in which 225 identifies the nominal section width in millimeters, 75 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On a 1991 Cadillac Brougham, that means a modern radial fitment suited to the car’s full-size luxury character and 15-inch wheel setup. Available choices include BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar, with both narrow and wide whitewall presentations. For most Brougham owners, this size is about selecting the right look and specifications within the correct fitment rather than sorting through multiple primary sizes.
Tire fitment is straightforward across the covered 1991 Cadillac Brougham sub-models because both use the same 225/75R15 radial size. Checking the sub-model still helps confirm the car’s trim identity before choosing among whitewall styles and tire series.

1991 Cadillac Brougham Base
The 1991 Cadillac Brougham Base uses the same 225/75R15 radial fitment as the rest of the range. That keeps tire selection focused on appearance and product details, such as narrow versus wide whitewall styling and the rim-width specifications of the tire under consideration.
The 1991 Cadillac Brougham d'Elegance also uses 225/75R15 radial tires on a 15-inch wheel. Tire choice here comes down to the presentation you want on the car, along with making sure the selected tire matches the actual wheel width and overall setup on the vehicle.
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 1991 Cadillac Brougham?
The 1991 Cadillac Brougham uses a 225/75R15 radial tire. That is the primary fitment for this model and it applies across both the Base and d'Elegance sub-models, which keeps size selection simple compared with vehicles that split fitment by trim or wheel package.
The practical decision is choosing the right tire within that size rather than trying to sort between multiple primary sizes. Whitewall width, brand, tire series, and wheel-width compatibility are the details worth comparing, especially if the car has replacement wheels or has been sitting long enough that its current tires no longer reflect the correct setup.
What size rim does a 1991 Cadillac Brougham use?
The 1991 Cadillac Brougham uses a 15-inch rim with its 225/75R15 tire size. That 15 at the end of the tire size identifies the wheel diameter, so any tire in this fitment is built around a 15-inch wheel rather than a larger or smaller rim.
Wheel diameter is only part of the check, though. Product fitments in this size also carry specific wheel-width ranges, so it is smart to confirm the actual width of the wheels on the car before choosing among available tires. That matters even more if the Brougham has aftermarket wheels or replacement factory-style rims.
Do all 1991 Cadillac Brougham sub-models use the same tire size?
Yes. Both the 1991 Cadillac Brougham Base and the 1991 Cadillac Brougham d'Elegance use the same 225/75R15 radial tire size. There is no split primary tire size between these covered sub-models, which makes fitment more straightforward than on many multi-trim vehicles.
That shared fitment means tire selection is mostly about product character rather than sub-model differences. Owners can focus on whitewall style, brand, and tire series, while still checking the actual wheel width and overall vehicle setup. A long-owned or modified Brougham may no longer be riding on its original-style wheels, so verification remains worthwhile.
Choosing the Right Tire
What should I consider when choosing a 225/75R15 tire for a 1991 Cadillac Brougham?
Start with the correct size and construction: 225/75R15 radial on a 15-inch wheel. From there, the important comparisons are sidewall appearance, brand, tire series, wheel-width compatibility, and load specification. On a large luxury sedan like the Brougham, those details shape both the visual presentation and the suitability of the tire for the car’s use.
A wide whitewall creates a more formal traditional look, while a narrower whitewall gives a subtler presentation. It also helps to compare the wheel-width range of each tire against the actual wheels on the car and to make sure the tire choice matches how the Brougham will be used, whether for local cruising, events, or longer highway driving.
What sidewall styles are available for 1991 Cadillac Brougham tires?
225/75R15 tires for the 1991 Cadillac Brougham are available with both narrow whitewall and wide whitewall styling. That gives owners room to choose between a more restrained sidewall treatment and a fuller whitewall presentation that better emphasizes the Brougham’s traditional luxury-sedan character.
The right choice depends on the look you want from the car rather than a universal rule. A wide whitewall tends to stand out more on a formal Cadillac body, while a narrow whitewall keeps the appearance cleaner and less pronounced. Matching the sidewall style to the car’s trim, wheel covers, and restoration direction usually matters more than chasing one appearance for every example.
What brands offer tires for the 1991 Cadillac Brougham?
Available 225/75R15 tires for the 1991 Cadillac Brougham include options from BFGoodrich, Coker Classic, American Classic, Maxxis, and Travelstar. The assortment includes named series such as Silvertown Radial, Star Series, American Classic Radial, and Travelstar UN106, along with different whitewall treatments.
Brand choice should be weighed alongside the rest of the tire’s specifications rather than treated as the only deciding factor. Comparing sidewall width, wheel-width compatibility, load figure, and the overall visual character of the tire gives a clearer picture of which option suits the car. That is especially important on a Brougham, where appearance and fitment both matter.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Cadillac Brougham?
A period-style 1991 Cadillac Brougham tire choice usually starts with the correct 225/75R15 radial size and then moves to sidewall presentation. Wide whitewall and narrow whitewall options are both available, so the appearance can be tailored toward a more formal traditional look or a more understated late-model luxury-sedan presentation.
The best visual match depends on the specific car, its trim, and the restoration direction rather than one fixed answer for every Brougham. Owners seeking a highly exact appearance should compare the tire against original photos, sales literature, or marque-specific references. For many drivers, staying in the proper size and choosing the right whitewall style achieves the look they want.
Does correct tire fitment matter for a 1991 Cadillac Brougham restoration?
Yes, correct tire fitment matters because the 1991 Cadillac Brougham is a large, formal car whose stance depends heavily on tire size and sidewall appearance. Using the proper 225/75R15 radial size helps preserve the intended visual proportion at the wheel opening and keeps the car aligned with its collector-era luxury character.
Appearance is only part of the picture. Correct fitment also means checking that the selected tire suits the wheel width actually on the car and that the overall setup clears properly during steering and suspension movement. A restoration can look right from across the lot yet still need closer fitment verification before regular road use.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Cadillac Brougham?
Yes. Even though the primary tire size for a 1991 Cadillac Brougham is 225/75R15, modifications can change whether a given tire remains appropriate for the car. Aftermarket wheels, wheel-width changes, altered offset, suspension work, or ride-height changes can all affect how the tire sits and clears.
That is why the car itself should be checked before assuming any replacement tire is suitable just because the size matches. Measuring the actual wheel width, confirming the 15-inch wheel diameter, and looking at steering and fender clearance can prevent problems. These checks are especially worthwhile on older cars that may have passed through several owners.
What should I inspect before driving a 1991 Cadillac Brougham on new tires?
Before driving a 1991 Cadillac Brougham on new tires, inspect the wheels for condition and correct size, confirm the tires are seated properly, and set inflation to the appropriate pressure for the tire and vehicle application. It also makes sense to look over suspension and steering components on a collector-age full-size Cadillac.
A short initial road check can reveal issues that a parked inspection may miss. Watch for vibration, pulling, rubbing during turns, or uneven ride height, and recheck pressures after the first drives. Looking over the spare and the car’s jack equipment is also smart if the Brougham will be used for longer trips rather than short local outings.
How should 225/75R15 tires on a collector 1991 Cadillac Brougham be maintained?
225/75R15 tires on a collector 1991 Cadillac Brougham should be maintained with regular pressure checks, routine visual inspections, and attention to aging as well as tread wear. Low-use collector cars often accumulate time faster than miles, so sidewall cracking, flat spotting, air loss, and general age-related deterioration deserve close attention.
Storage conditions matter almost as much as driving habits. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps protect the tires between outings. It also pays to inspect the tires before every meaningful drive, since a Brougham that sits for long periods can develop issues that are easy to miss until road speed rises.
