The 1980 Buick Century sits in the transitional era when midsize American cars blended traditional Buick comfort with downsized packaging and more modern road manners. Buyers today often approach one as either a well-kept survivor, a practical cruiser, or a period-minded restoration. Tire fitment on the 1980 Buick Century stays firmly in the radial era, with 14-inch fitments in 185/75R14, 195/75R14, and 205/70R14 depending on sub-model and wheel setup. That opens the door to meaningful choices in whitewall width, redline, raised white letter, and blackwall presentation across several brands and series. The key is matching the correct size to the exact Century configuration before choosing the look and driving character you want.
Which Tire Size Is Right for The 1980 Buick Century
The 1980 Buick Century uses three primary tire sizes, and the right one depends on the exact sub-model. All three are radial tires for 14-inch wheels, so the first step is confirming whether your Century is a Base, Limited, Sport, Estate, Wagon, or aluminum-wheel variation. Once the correct size is established, the decision shifts to sidewall style, tire series, brand, and the kind of period look you want the car to carry.
Fit(s): Base, Limited, Limited w/aluminum wheels, and w/aluminum wheels
Construction: Radial|Rim: 14 in
185/75R14 is a metric radial size with a 185-millimeter section width, a 75-series profile, and a fitment for a 14-inch rim. On the 1980 Buick Century, this size suits selected Base and Limited configurations and stays true to the car's modern-for-its-era radial construction. Available choices lean toward a traditional whitewall presentation, including narrow whitewall options from Tornel, Maxxis, and Travelstar across several tire series. This size makes the most sense when your Century's exact sub-model and wheel setup call for it and you want a stock-style radial look rather than a sportier sidewall treatment.
195/75R14 uses the same metric radial sizing system, with a slightly wider 195-millimeter section width, a 75-series profile, and a 14-inch rim diameter. It appears across several 1980 Buick Century configurations, including Base, Limited, and certain Wagon and aluminum-wheel applications, making it one of the most broadly used Century sizes. Product choices include both narrow and wide whitewall treatments from Coker Classic, Tornel, Maxxis, and Travelstar, with series differences that affect appearance and rim-width compatibility. This is the size to evaluate carefully if your Century falls into one of the shared-fitment sub-model groups.
Fit(s): Estate, Estate w/aluminum wheels, Sport, Sport w/aluminum wheels, Wagon, and Wagon w/aluminum wheels
Construction: Radial|Rim: 14 in
205/70R14 is a metric radial with a 205-millimeter section width, a lower 70-series profile, and a 14-inch rim fitment. On the 1980 Buick Century, it is used on Estate and Sport versions and also appears on some Wagon applications, giving those cars a distinct sizing path from the 75-series fitments. This size offers the broadest visual variety, with narrow whitewall, raised white letter, redline, dual redline, and blackwall choices from Maxxis, BFGoodrich, and Michelin. It is the right place to look when the goal is a more assertive period-style appearance without stepping away from the correct primary radial format.
Sub-model fitment matters on the 1980 Buick Century because tire size is not the same across the full range. Every version uses a 14-inch radial tire, but the correct size changes by body style and wheel configuration, so identifying the exact Century sub-model comes before comparing products.

1980 Buick Century Base
The 1980 Buick Century Base uses either 185/75R14 or 195/75R14 radial tires. That means the owner should confirm the actual wheel and current setup first, then choose among the available whitewall-focused product options in the matching size.
The 1980 Buick Century Estate uses the 205/70R14 radial size. Tire selection here can move beyond basic fitment into appearance, since this size is available with whitewall, redline, dual redline, raised white letter, and blackwall presentations.
The 1980 Buick Century Estate w/aluminum wheels also uses 205/70R14 radials. Once the wheel setup is confirmed, the main decision becomes which sidewall style and tire series best suit the wagon's intended period look and road use.
The 1980 Buick Century Limited uses either 185/75R14 or 195/75R14 radial tires. Buyers should verify which of those two sizes is on the car before narrowing the choice to wide or narrow whitewall styling and the available brand options.
The 1980 Buick Century Limited w/aluminum wheels shares the 185/75R14 or 195/75R14 radial fitment pattern. That makes wheel confirmation especially important before selecting a replacement tire or trying to preserve a restoration-oriented appearance.
The 1980 Buick Century Sport uses 205/70R14 radial tires. That opens up a broader range of visual choices than the 75-series sizes, including sportier sidewall treatments that may better match the trim and stance of a Century Sport.
The 1980 Buick Century Sport w/aluminum wheels uses the same 205/70R14 radial size. Selection is less about finding the size and more about deciding whether the car looks right with RWL, redline, blackwall, or a more traditional whitewall treatment.
The 1980 Buick Century Wagon can use either 195/75R14 or 205/70R14 radial tires. That makes the wagon one of the Century variants where confirming the exact wheel and existing fitment is essential before comparing style and series differences.
The 1980 Buick Century Wagon w/aluminum wheels also uses either 195/75R14 or 205/70R14 radials. Owners should settle the actual size on the vehicle first, then choose the appearance and product character that best match the wagon's intended presentation.
The 1980 Buick Century w/aluminum wheels uses either 185/75R14 or 195/75R14 radial tires. With two possible sizes in play, the practical next step is confirming the wheel and current tire setup before selecting among the available whitewall radial options.
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 1980 Buick Century?
A 1980 Buick Century can use 185/75R14, 195/75R14, or 205/70R14, depending on the exact sub-model and wheel configuration. Base and Limited versions can use 185/75R14 or 195/75R14, while Estate and Sport versions use 205/70R14. Wagon applications can use 195/75R14 or 205/70R14.
That means the correct first step is identifying the exact Century version before choosing a tire. Even though every listed fitment uses a 14-inch radial, the section width and profile differ, so the owner should confirm the current wheel setup and the size already on the car before moving on to sidewall style or brand selection.
What size rim does a 1980 Buick Century use?
The listed tire fitments for the 1980 Buick Century all use a 14-inch rim diameter. That applies across 185/75R14, 195/75R14, and 205/70R14, so the Century stays within one wheel diameter even though the tire size changes from one sub-model to another.
A shared 14-inch rim diameter does not mean every Century automatically uses the same tire. Width and profile still vary, and some product options also call for different rim-width ranges. Checking the actual wheel on the car is still worthwhile, especially if the Century has aluminum wheels, replacement rims, or an older tire size that may not match the original setup now installed.
Why does the 1980 Buick Century have more than one tire size?
The 1980 Buick Century has more than one tire size because fitment varies by sub-model and wheel configuration. Buick offered the Century in several forms, and those versions use different radial sizes even though they all stay on a 14-inch wheel diameter.
The practical takeaway is that a Century owner should not select a tire by year and model name alone. Base, Limited, Sport, Estate, Wagon, and aluminum-wheel versions can follow different size paths, so the safest approach is to match the tire to the exact sub-model and then confirm the current wheel and clearance setup before replacing all four tires.
Choosing the Right Tire
What should I consider when choosing a 1980 Buick Century tire?
Start with the exact tire size required for the specific 1980 Buick Century sub-model, since the car may use 185/75R14, 195/75R14, or 205/70R14. From there, compare construction, rim-width compatibility where stated, load capacity figures, and the sidewall treatment that best matches the car's intended look.
A Century kept as a clean survivor may call for a traditional whitewall presentation, while a Sport or Estate owner may prefer redline, RWL, or blackwall styling if that suits the car's personality. Product series also differ, so it is worth comparing details carefully once the size is settled rather than choosing only by brand name or appearance.
What sidewall styles are available for 1980 Buick Century tires?
Sidewall choices for the 1980 Buick Century include narrow whitewall, wide whitewall, redline, dual redline, raised white letter, and blackwall, depending on the tire size. The 185/75R14 and 195/75R14 options lean toward whitewall styling, while 205/70R14 brings the widest spread of visual treatments.
That makes sidewall style an important part of the buying decision once the correct size is confirmed. A wide whitewall can give a more traditional Buick look, while redlines or RWL can push the car toward a stronger late-classic performance flavor. The right choice depends on the Century's trim, wheels, and the kind of period presentation the owner wants to emphasize.
What brands offer tires for the 1980 Buick Century?
Tires for the 1980 Buick Century are available from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin, depending on size. Brand availability changes across the three fitments, so the selection for 185/75R14 is not identical to the selection for 195/75R14 or 205/70R14.
That variation means the best way to compare brands is within the exact size your Century uses. Some sizes focus on whitewall touring-style options, while 205/70R14 adds sportier visual choices and a broader series mix. It helps to compare brand offerings alongside sidewall style, load figures, and wheel compatibility rather than treating the brand name as the only decision point.
Restoration & Appearance
Which tire should I choose for a period-style 1980 Buick Century?
A period-style 1980 Buick Century starts with the correct primary size for the exact sub-model, then moves to the visual tone you want. Whitewall radials are a natural fit for a more formal Buick presentation, while 205/70R14 opens the door to redline, dual redline, raised white letter, or blackwall choices on the right Century configuration.
The best-looking result usually comes from matching the tire's sidewall character to the car's trim, wheel style, and intended era feel rather than choosing by size alone. If absolute originality matters, it is worth checking marque references or period sales material before settling on a stripe width or sidewall treatment for a restoration-focused car.
How does tire construction affect the appearance of a restored 1980 Buick Century?
On the 1980 Buick Century, construction is less about bias-ply versus radial debate and more about choosing the right radial presentation. The Century's primary fitments are already radial, so appearance differences come mainly from profile, sidewall style, and series character rather than from a shift between vintage and modern constructions.
That gives a restorer room to tune the visual result without leaving the proper radial format. A narrow or wide whitewall can pull the car toward a softer luxury look, while redlines or RWL can make some trims feel more performance-oriented. Keeping the correct size tied to the exact sub-model remains the foundation of an authentic-looking stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1980 Buick Century?
Yes. A 1980 Buick Century may have the correct nominal tire size on paper and still run into fitment issues if the car has aftermarket wheels, altered wheel offset, replacement suspension parts, or changes in ride height. Those changes can affect clearance even when the tire still matches one of the proper 14-inch Century sizes.
That is why modified cars should be checked at the wheel openings and through the steering range before new tires are chosen. Looking at actual wheel width also matters, since some available Century tires carry specific rim-width guidance. A quick inspection now can prevent rubbing, stance issues, or mismatched appearance once the new set is mounted.
What should I inspect before driving a 1980 Buick Century on new tires?
Before driving a 1980 Buick Century on new tires, inspect the wheels for damage, verify that the tire size matches the exact sub-model, and make sure the tires are inflated properly for the setup in use. It also helps to look over the suspension and steering components so the new tires are not being asked to compensate for worn hardware.
A short follow-up check after installation is smart on any collector-era car. Watch for uneven clearance, rubbing at full lock, vibration, or unusual wear patterns as the tires begin service. If the Century has spent long periods parked, also inspect the spare and confirm that all four road tires are free of cuts, bulges, or signs of mounting damage.
How should 1980 Buick Century tires be maintained?
Tires on a 1980 Buick Century should be checked regularly for air pressure, tread wear, cracking, cuts, bulges, and signs of aging, especially if the car is driven only occasionally. Collector-era cars often accumulate miles slowly, so condition matters just as much as tread depth when evaluating whether a tire is still roadworthy.
Storage habits also affect service life. Keeping the Century out of prolonged heat, direct sunlight, and ozone-heavy environments can help preserve the sidewalls and maintain appearance. It is also wise to inspect the car before longer drives, since a low-use vehicle may look fine at a glance while still hiding air loss or age-related deterioration.
