The 1991 Buick Century sits squarely in the front-drive American midsize sedan era, when comfort, clean packaging, and everyday usability mattered more than flashy performance. For many owners today, that makes tire choice less about chasing extremes and more about preserving the car’s composed road manners and period-appropriate look. The 1991 Buick Century uses radial tires in two 14-inch sizes, 185/75R14 and 195/75R14, with fitment varying by sub-model. Available choices lean heavily toward whitewall styling, including narrow and wide whitewall options across several brands and series. The key is confirming the exact sub-model and wheel setup before choosing between the two sizes.
Which Tire Size Is Right for The 1991 Buick Century
The 1991 Buick Century uses two primary tire sizes, and both are radial tires built for 14-inch rims. The first step is identifying the exact sub-model, because Special models use one size while Custom and Limited models can use either size. Once that is confirmed, the decision shifts to the look and character of the tire, including whitewall width, brand, and series.
185/75R14 is a metric radial size in which 185 identifies the nominal section width in millimeters, 75 is the aspect ratio, R marks radial construction, and 14 is the wheel diameter in inches. On the 1991 Buick Century, this is one of the primary 14-inch radial fitments and it is the sole size used on the Special sub-model. Available options center on traditional narrow whitewall styling from Tornel, Maxxis, and Travelstar across series such as Tornel Classic, Classic Whitewall MA-1, and UN106. This size suits owners who want to stay with the narrower of the Century’s two radial fitments while keeping a distinctly period-style presentation.
195/75R14 follows the same metric radial format, with a 195-millimeter nominal section width, a 75-series profile, radial construction, and a 14-inch rim diameter. On the 1991 Buick Century, this size applies to certain Custom and Limited applications and gives buyers the broader product range of the two primary fitments. Choices include narrow whitewall and wide whitewall designs from Coker Classic, Tornel, Maxxis, and Travelstar, with series such as Star Series, Coker Classic Radial, Tornel Classic, Classic Whitewall MA-1, and UN106. It is the size to evaluate when your Century uses the larger primary fitment and sidewall appearance is part of the decision.
Tire fitment on the 1991 Buick Century is mostly straightforward, but the exact sub-model still matters. Special models use one size, while Custom and Limited models can use either of the two 14-inch radial fitments, so confirming the badge and current wheel setup helps avoid ordering the wrong tire.

1991 Buick Century Custom
The 1991 Buick Century Custom can use either of the two primary 14-inch radial sizes offered for this model year. That means the most important next step is checking which size is currently on the car and making sure the wheel and overall setup match before choosing a sidewall style or tire series.
The 1991 Buick Century Limited also spans both primary 14-inch radial tire sizes. Tire selection starts with confirming which of those two sizes belongs on the car’s present wheel package, then narrowing the choice by whitewall treatment, brand, and the kind of period-style appearance you want.
The 1991 Buick Century Special uses the 185/75R14 radial size, making fitment simpler than on the other sub-models. With the size established, the decision becomes choosing among the available narrow whitewall options and confirming wheel condition and dimensions before putting the car back into regular road use.
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.

Common 1991 Buick Century tire questions usually center on choosing between 185/75R14 and 195/75R14, understanding which sub-model uses which size, and comparing whitewall, brand, and road-use considerations before installing new tires.
Tire Size & Fitment
What tire size fits a 1991 Buick Century?
A 1991 Buick Century uses one of two primary radial tire sizes: 185/75R14 or 195/75R14. Both sizes are built for 14-inch wheels, but they do not apply the same way across every sub-model. The Century Special uses 185/75R14, while Century Custom and Century Limited can use either 185/75R14 or 195/75R14.
That makes sub-model identification and wheel confirmation the first step before choosing a tire. If the car has been changed over the years, the current wheel size and the size already on the car should be checked against the intended replacement. Once the correct size is confirmed, the next decisions are usually whitewall style, brand, and tire series.
What size rim does a 1991 Buick Century use?
The 1991 Buick Century uses a 14-inch rim with both primary tire sizes. Whether the car uses 185/75R14 or 195/75R14, the tire is built around the same 14-inch wheel diameter. The difference between the two fitments is in tire width and overall dimensions, not a change in rim diameter.
Rim diameter is only part of the fitment check, especially on a collector-era driver that may have seen wheel changes over time. Wheel width still matters, and product options vary in their rim-width recommendations. Looking at the actual wheel on the car before ordering helps prevent a mismatch between the selected tire and the wheel currently installed.
Do all 1991 Buick Century sub-models use the same tire size?
No, not every 1991 Buick Century sub-model uses the same tire size. The Special uses 185/75R14, while the Custom and Limited are associated with both 185/75R14 and 195/75R14. That means the Century family shares a common 14-inch radial format, but not one single tire size across every covered version.
For an owner, that means the trim badge alone is helpful but not always the whole story on Custom and Limited cars. Checking the existing tire size, wheel width, and any prior changes made to the car is worthwhile before replacing tires. A Century that still wears its intended setup is much easier to match than one that has been altered.
Choosing the Right Tire
What should I consider when choosing a 1991 Buick Century tire?
Start with the correct size for the car: 185/75R14 or 195/75R14, depending on the sub-model and wheel setup. After that, focus on radial construction, the tire’s sidewall style, rim-width compatibility, and how the car will actually be used. On a 1991 Buick Century, appearance often matters just as much as basic fitment because many available tires use period-style whitewall treatments.
A Century used for casual cruising may call for a different visual approach than one being freshened for a more restoration-oriented presentation. Narrow whitewall and wide whitewall options create noticeably different looks. Comparing rim-width recommendations, load figures as stated for the tire, and the overall condition of the wheels helps narrow the choice without treating every 14-inch radial as interchangeable.
What sidewall styles are available for 1991 Buick Century tires?
The available sidewall styles for 1991 Buick Century tires center on whitewall designs. In these two 14-inch radial sizes, the product mix includes narrow whitewall options and wide whitewall options, depending on the exact size selected. The broader 195/75R14 fitment offers the most visible sidewall variety, including both traditional narrow whitewalls and wider whitewall presentations.
That choice affects the car’s personality more than many buyers expect. A narrow whitewall tends to keep the look restrained and late-model for the era, while a wide whitewall gives the Century a more formal, traditional appearance. Picking the sidewall first only works after the size is confirmed, since not every styling treatment appears in both primary fitments.
What brands offer tires for the 1991 Buick Century?
1991 Buick Century tires in these primary 14-inch radial sizes are available from Coker Classic, Tornel, Maxxis, and Travelstar. Brand availability varies by size, with 185/75R14 centered on Tornel, Maxxis, and Travelstar, while 195/75R14 adds Coker Classic options as well. The selection also spans multiple tire series rather than one uniform product type.
Brand choice is most useful when it helps narrow down the style and specification you want. Some buyers may be focused on wide whitewall presentation, while others want a narrower whitewall or a particular rim-width range. Comparing the actual size, sidewall treatment, and series details usually tells you more than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Buick Century?
A period-style 1991 Buick Century tire starts with the correct radial size for the exact car, then moves to the right visual treatment. In practice, that usually means choosing between 185/75R14 and 195/75R14 first, then selecting a narrow whitewall or wide whitewall option that matches the presentation you want for the car.
The Century’s early-1990s Buick character can look noticeably different depending on sidewall width. A restrained narrow whitewall keeps the appearance closer to everyday passenger-car trim, while a wide whitewall pushes the look in a more formal direction. For strict originality research, vehicle-specific references and marque-focused documentation are still the best way to confirm exact historical presentation.
How does tire construction affect the appearance of a restored 1991 Buick Century?
On a 1991 Buick Century, construction is less of an appearance debate than it is on older classics because the primary fitments are already radial. The bigger visual difference comes from sidewall treatment and tire series, especially the contrast between narrow whitewall and wide whitewall options available in the correct 14-inch sizes.
That means a restoration-minded buyer can stay within the proper radial theme while still shaping the car’s final look. A wide whitewall can give the Buick a dressier, more traditional impression, while a narrower stripe feels more understated. Matching the tire’s size and visual character to the wheel and trim package usually produces a more cohesive result than choosing by brand alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Buick Century?
Yes, modifications can affect tire fitment on a 1991 Buick Century even though the original fitments are straightforward 14-inch radials. Wheel changes, altered wheel width, suspension work, or changes in ride height can all influence which of the two primary sizes works best on the car. That matters most on Custom and Limited models, which span both sizes.
A Century that still uses its intended wheel setup is easier to match than one fitted with aftermarket wheels or non-original suspension parts. Checking current wheel diameter, wheel width, and visible clearance around the fenders and steering components helps avoid surprises. Replacement is much smoother when the actual car is verified instead of relying on assumptions from trim level alone.
What should I inspect before driving a 1991 Buick Century on new tires?
Before putting a 1991 Buick Century back on the road with new tires, inspect the wheels for damage, confirm the wheel diameter and width, and make sure the selected tire size matches the car’s intended setup. It also makes sense to look over the suspension, steering components, and alignment condition so the new tires are not immediately compromised.
Road readiness goes beyond the tires themselves, especially on a car that may not see daily use. Air pressure, lug hardware, valve stems, and signs of rubbing should be checked before a longer drive. A short local drive followed by another inspection can reveal clearance or handling issues early, before they become wear problems.
How should 185/75R14 and 195/75R14 tires on a collector 1991 Buick Century be maintained?
Collector-use 185/75R14 and 195/75R14 tires on a 1991 Buick Century should be maintained with regular pressure checks, routine visual inspection, and attention to aging even if tread wear is minimal. Sidewall cracking, bulges, cuts, and slow air loss matter just as much on a lightly used Buick as they do on a regularly driven one.
Storage conditions make a difference over time. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve both the tire structure and the whitewall appearance. Occasional movement to avoid long-term flat spotting is also useful, and any Century that has been sitting for an extended period deserves a thorough inspection before sustained road use.
