The 1981 Buick Century came from a period when midsize American cars were balancing traditional Buick comfort with more modern packaging and road manners. Whether kept as a sedan, wagon, or estate-bodied family cruiser, it is a vehicle that benefits from getting the tire size right before appearance choices come into play. The 1981 Buick Century uses radial tires on 14-inch rims, with 185/75R14, 195/75R14, and 205/70R14 fitments depending on sub-model. That opens up meaningful choices in whitewall width, redline, raised white letter, and blackwall presentation across several tire series and brands. The key is matching the correct size to the exact Century configuration and wheel setup.
Which Tire Size Is Right for The 1981 Buick Century
Three tire sizes apply to the 1981 Buick Century, and the right one depends on the exact sub-model rather than a change in wheel diameter. All three are radial fitments for 14-inch rims, but sedan, sport, limited, estate, and wagon versions do not all share the same size range. The first step is confirming the specific Century model and whether it has the wheel configuration associated with that fitment before comparing sidewall style, brand, or tire series.
Fit(s): Base, Limited, Limited w/aluminum wheels, Sport, Sport w/aluminum wheels, and w/aluminum wheels
Construction: Radial|Rim: 14 in
The 185/75R14 size uses a metric width designation, a 75-series aspect ratio, radial construction, and a 14-inch rim diameter. On the 1981 Buick Century, it serves as one of the primary radial fitments for several sedan-based sub-models and keeps the sizing in a traditional late-classic domestic range. Available choices center on narrow whitewall presentation from Tornel, Maxxis, and Travelstar across different series. This size is worth considering when the vehicle calls for it and the goal is to stay with the proper fitment while choosing a whitewall style that suits the car's character.
The 195/75R14 size follows the same metric radial sizing system, with a slightly wider section than 185/75R14 while retaining a 75-series profile and 14-inch rim fitment. It is the broadest-application tire size in the 1981 Buick Century range, appearing across multiple sub-models including base, limited, sport, and wagon-related versions. Product choices include narrow whitewall and wide whitewall styles from Coker Classic, Tornel, Maxxis, and Travelstar in several tire series. This is the size to evaluate carefully when your Century uses it, especially if appearance is as important as maintaining the correct overall fitment pattern.
Fit(s): Estate, Estate w/aluminum wheels, Wagon, and Wagon w/aluminum wheels
Construction: Radial|Rim: 14 in
The 205/70R14 size is a metric radial with a wider 205-millimeter section and a lower 70-series profile, still built for a 14-inch rim. On the 1981 Buick Century, it is associated with estate and wagon-oriented sub-models, where it creates a different fitment path from the 75-series sedan sizes. This size brings the widest appearance variety, including narrow whitewall, redline, dual-redline, raised white letter, and blackwall offerings from Maxxis, BFGoodrich, and Michelin. It is the right size to review when the vehicle calls for it and the buyer wants to balance correct fitment with a more tailored period-style look.
Sub-model fitment matters on the 1981 Buick Century because tire sizing is shared within some groups but not across the full lineup. Sedan, sport, limited, estate, and wagon versions can overlap on one size while differing on the second, so confirming the exact model is the first step before choosing a tire.

1981 Buick Century Base
The 1981 Buick Century Base uses the 185/75R14 and 195/75R14 radial fitment range on 14-inch rims. That gives the owner a choice within the proper size range, with tire selection focused on matching the car's actual wheel setup and preferred whitewall presentation.
The 1981 Buick Century Estate uses 195/75R14 and 205/70R14 radial tires rather than the narrower 185-series option. Tire selection here starts with confirming which of those two sizes belongs on the car, then choosing among whitewall, redline, raised white letter, or blackwall styles where available.
The 1981 Buick Century Estate w/aluminum wheels also falls into the 195/75R14 and 205/70R14 radial fitment group. That makes wheel confirmation especially important, since the buying decision centers on the correct size first and appearance details such as sidewall treatment second.
The 1981 Buick Century Limited uses 185/75R14 and 195/75R14 radial tires on 14-inch rims. Once the correct size is confirmed, the next decision usually comes down to whitewall width, brand preference, and how traditional or understated the finished look should be.
The 1981 Buick Century Limited w/aluminum wheels shares the 185/75R14 and 195/75R14 radial size range. Tire choice is straightforward once the installed wheel setup is verified, with the main differences coming from sidewall styling and the character of the available tire series.
The 1981 Buick Century Sport uses 185/75R14 and 195/75R14 radial tires rather than the wagon and estate 205/70R14 option. That makes the decision less about construction and more about selecting the correct size, then choosing the whitewall treatment that best suits the car.
The 1981 Buick Century Sport w/aluminum wheels remains in the 185/75R14 and 195/75R14 radial fitment group. The practical choice is verifying which of those sizes is on the car now and selecting a tire that matches both wheel compatibility and desired appearance.
The 1981 Buick Century Wagon uses 195/75R14 and 205/70R14 radial tires on 14-inch rims. Because both sizes appear in this sub-model, checking the existing wheel-and-tire setup is important before comparing the broader appearance choices available in the 205/70R14 range.
The 1981 Buick Century Wagon w/aluminum wheels also uses 195/75R14 and 205/70R14 radial fitments. Buyers should confirm the actual size on the vehicle first, then compare sidewall style, rim-width compatibility, and tire series within the correct size.
The 1981 Buick Century w/aluminum wheels uses 185/75R14 and 195/75R14 radial tires. That keeps the fitment in the sedan-style size group, with the main decision centered on choosing the right size first and the preferred whitewall look after that.
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.

Owners usually need to sort out which of the three 14-inch radial sizes belongs on their exact 1981 Buick Century, then compare whitewall and performance-oriented appearance options. The questions below cover size meaning, sub-model differences, product selection, and practical fitment checks before road use.
Tire Size & Fitment
What tire size fits a 1981 Buick Century?
The 1981 Buick Century uses three radial tire sizes across the model range: 185/75R14, 195/75R14, and 205/70R14. Base, Limited, Sport, and related aluminum-wheel versions use 185/75R14 or 195/75R14, while Estate and Wagon versions use 195/75R14 or 205/70R14.
The practical choice starts with identifying the exact Century sub-model and then confirming the size already associated with the car. Since all three fitments share a 14-inch rim diameter, the deciding factor is usually the vehicle configuration rather than wheel diameter alone.
What size rim does a 1981 Buick Century use?
The tire fitments for the 1981 Buick Century are built around a 14-inch rim diameter. That applies across the 185/75R14, 195/75R14, and 205/70R14 sizes, so the Century stays within one wheel diameter even though tire width and profile vary by sub-model.
That does not mean every 14-inch tire is interchangeable on every Century. Wheel width, the exact tire size, and the car's sub-model still need to line up, especially if the vehicle has aluminum wheels or has been changed from its original wheel-and-tire setup.
Why does the 1981 Buick Century have more than one tire size?
The 1981 Buick Century has more than one tire size because the lineup includes several sub-model groupings with different fitment ranges. Sedan-based versions use 185/75R14 or 195/75R14, while Estate and Wagon versions use 195/75R14 or 205/70R14, all in radial construction.
That makes the tire decision more specific than simply searching by year, make, and model. Matching the tire to the exact sub-model helps narrow the correct size first, after which sidewall style, tire series, and brand differences can be compared within the proper fitment.
Choosing the Right Tire
What should I consider when choosing a 1981 Buick Century tire?
Start with the correct size for the exact 1981 Buick Century sub-model: 185/75R14, 195/75R14, or 205/70R14. After size is confirmed, compare construction details within the available radial choices, including rim-width specifications where stated, load capacity figures, tire series, and sidewall presentation.
The best choice depends on how the car is used and how it should look. A traditional whitewall may suit a comfortable boulevard presentation, while a redline, raised white letter, or blackwall tire can shift the visual tone of the car without changing the required rim diameter.
What sidewall styles are available for 1981 Buick Century tires?
Sidewall choices for the 1981 Buick Century include narrow whitewall, wide whitewall, redline, dual-redline, raised white letter, and blackwall, depending on tire size. The broadest appearance range shows up in 205/70R14, while 185/75R14 and 195/75R14 focus primarily on whitewall presentations.
That means sidewall style should be chosen only after confirming the correct size for the car. Owners trying to preserve a more formal Buick look may lean toward whitewalls, while sportier presentations often point buyers toward the redline or raised white letter options available in the larger fitment.
What brands offer tires for the 1981 Buick Century?
Tires for the 1981 Buick Century are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin, depending on the size. Brand availability changes across 185/75R14, 195/75R14, and 205/70R14, so not every brand appears in every Century fitment.
Brand choice matters less than getting the correct size and the right visual style for the car. Once the fitment is confirmed, comparing brand offerings by tire series, sidewall treatment, and wheel-width compatibility gives a clearer basis for selection than choosing by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1981 Buick Century?
A period-style 1981 Buick Century tire starts with the correct radial size for the sub-model and then moves to appearance. Whitewall tires are the most prominent traditional-looking option in the Century range, with narrow and wide whitewall choices available depending on whether the car uses 185/75R14 or 195/75R14.
The right look depends on the way the car is being presented, not just on fitment alone. Owners seeking a historically consistent restoration-oriented appearance should compare the installed wheels, trim level, and surviving reference photos or marque-specific documentation before settling on a sidewall treatment.
How does tire construction affect the appearance of a restored 1981 Buick Century?
Construction is less of a visual issue here than it is on earlier collector cars because the 1981 Buick Century uses radial primary fitments. The stronger appearance difference comes from the sidewall itself, with whitewall, redline, raised white letter, and blackwall designs changing the car's overall character far more noticeably.
That makes size and sidewall style the main restoration decisions on this Century. A formal sedan or wagon may call for a more traditional whitewall presentation, while a sport-oriented build can look very different on redlines or raised white letters even when the tire remains in the correct radial fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1981 Buick Century?
Yes. A 1981 Buick Century may have the correct 14-inch rim diameter yet still run into fitment issues if aftermarket wheels, changed wheel widths, suspension alterations, or body modifications are present. Those changes can affect how a 185/75R14, 195/75R14, or 205/70R14 tire sits in the wheel opening.
Clearance should be checked at full steering lock and through suspension movement before settling on a replacement tire. The need for verification becomes even more important when the car has aluminum wheels or when the current wheel-and-tire package differs from the original Century setup.
What should I inspect before driving a 1981 Buick Century on new tires?
Inspect the wheels for correct diameter and sound condition, then verify that the installed tire size matches the Century sub-model. It also helps to look over valve stems, air pressure, tread seating, and visible clearance around the fenders, suspension, and steering components before putting miles on the car.
Collector and low-use cars deserve extra attention because age can affect more than just the old tires that came off. A short test drive followed by a recheck for rubbing, air loss, and even wear can catch setup issues early, especially when changing to a different size within the Century range.
How should 1981 Buick Century tires be maintained?
1981 Buick Century tires should be maintained with regular pressure checks, routine visual inspection, and attention to age-related condition. Watch for cracking, bulges, cuts, uneven tread wear, and slow air loss, particularly on cars that sit for long periods or are driven only seasonally.
Storage conditions matter on a collector-era Buick. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, while periodic inspection of alignment and suspension condition can prevent wear problems that shorten the life of otherwise good radial tires.
