The 1984 Buick Century sits squarely in Buick’s front-wheel-drive, mid-1980s transition period, when comfort, efficiency, and clean contemporary packaging shaped the character of the car. Whether kept as a well-preserved family sedan, wagon, or sporty T-Type, the right tire choice has a noticeable effect on stance, ride quality, and period appearance. This Buick Century uses 14-inch radial tire fitments, with size choice varying by sub-model and configuration. Available options range from whitewall touring-style radials to blackwall and raised white letter selections tied to more sporting applications. The key is matching the correct size to the exact sub-model, then choosing the sidewall look and tire character that suit the car.
Which Tire Size Is Right for The 1984 Buick Century
The 1984 Buick Century uses four primary tire sizes, and the right one depends on the exact sub-model. All of them are radial tires for 14-inch wheels, but the fitment splits between traditional higher-profile sizes used on Custom, Estate, Limited, and Olympia Limited models and lower-profile sizes used on the T-Type. Identifying the sub-model and confirming the wheel setup should come before comparing tire style or appearance.
Fit(s): Custom (Diesel), Custom (Gas), Estate (Diesel), Estate (Gas), Limited (Diesel), Limited (Gas), Olympia Limited (Diesel), and Olympia Limited (Gas)
Construction: Radial|Rim: 14 in
195/75R14 is a metric radial size in which 195 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 14 is the wheel diameter in inches. On the 1984 Buick Century, this higher-profile radial is used on several diesel sub-models and also appears on certain gas-powered versions. Available choices include Coker Classic, Tornel, Maxxis, and Travelstar, with wide whitewall and narrow whitewall presentations across several tire series. It is the size to evaluate when preserving a traditional 1980s touring look on the correct Century configuration.
Fit(s): Custom (Gas), Estate (Gas), Limited (Gas), and Olympia Limited (Gas)
Construction: Radial|Rim: 14 in
185/75R14 follows the same metric radial format, with a 185-millimeter nominal width, a 75-series profile, radial construction, and a 14-inch rim. This size appears on certain gas-powered 1984 Buick Century Custom, Estate, Limited, and Olympia Limited models, where it serves as a slightly narrower companion to 195/75R14 fitment. Product choices center on Tornel, Maxxis, and Travelstar, all offered with narrow whitewall styling that suits a traditional driver-oriented presentation. This size deserves close attention when the car is a gas model and the goal is to stay with the proper fitment family rather than move into sportier T-Type sizing.
195/70R14 uses a 195-millimeter nominal width, a lower 70-series aspect ratio, radial construction, and a 14-inch wheel diameter. On the 1984 Buick Century, this size is associated with the T-Type, where it reflects a more performance-minded fitment than the taller touring sizes used on other sub-models. The available product in this size is a Dunlop Sport Classic with a blackwall presentation, giving it a distinctly cleaner and more sporting visual character. It is the size to examine when the car is a T-Type and the intent is to retain the model’s lower-profile radial look.
215/60R14 is a metric radial size with a 215-millimeter nominal width, a 60-series profile, radial construction, and a 14-inch rim. This lower-profile fitment is also used on the 1984 Buick Century T-Type, pairing a wider tread section with a shorter sidewall than the Century’s touring-oriented sizes. The available choice is a BFGoodrich Radial T/A with raised white letter sidewalls, a presentation that strongly matches the performance image many owners want from a T-Type. This size is worth considering only after confirming the car’s actual T-Type wheel and clearance setup.
Sub-model identification matters on the 1984 Buick Century because fitment is not the same across the range. Most Custom, Estate, Limited, and Olympia Limited versions stay within the taller 185/75R14 and 195/75R14 family, while the T-Type uses lower-profile 14-inch radial sizes of its own.

1984 Buick Century Custom (Diesel)
The 1984 Buick Century Custom (Diesel) uses the taller 195/75R14 radial fitment rather than the narrower or sport-oriented alternatives seen elsewhere in the lineup. Tire choice here centers more on whitewall style, brand, and overall presentation than on deciding between multiple fitment families.
The 1984 Buick Century Custom (Gas) can use either 185/75R14 or 195/75R14, so confirming the car’s actual wheel and tire setup is important before replacing anything. Once the correct size is established, the decision usually shifts to narrow whitewall appearance and brand or series preference.
The 1984 Buick Century Estate (Diesel) uses 195/75R14 radial tires, keeping it in the same taller-profile fitment group as several other diesel Century models. That makes selection more about choosing the right whitewall look and tire character for a wagon that is being preserved or driven regularly.
The 1984 Buick Century Estate (Gas) uses either 185/75R14 or 195/75R14, so the first step is matching the replacement tire to the wheel and size already on the car. That distinction matters because the available products stay within traditional narrow or wider whitewall touring-style radial options rather than the T-Type’s lower-profile fitments.
The 1984 Buick Century Limited (Diesel) uses 195/75R14 radial tires, placing it in the Century’s more traditional touring-oriented fitment group. Buyers can focus on whitewall width, tire series, and brand character while keeping the proper 14-inch radial size in place.
The 1984 Buick Century Limited (Gas) can be fitted with either 185/75R14 or 195/75R14, so the exact wheel-and-tire combination should be confirmed first. After that, the main choice becomes selecting the sidewall style and product line that best suit a clean, period-style Century appearance.
The 1984 Buick Century Olympia Limited (Diesel) uses 195/75R14 radial tires on 14-inch wheels, sharing the taller touring-style fitment seen on other diesel Century variants. That setup points the buyer toward whitewall radial choices rather than the lower-profile tires associated with the T-Type.
The 1984 Buick Century Olympia Limited (Gas) uses either 185/75R14 or 195/75R14, making size confirmation the first priority before comparing products. Once the correct fitment is established, selection is largely about choosing among narrow whitewall or broader whitewall-style radial options where available.
The 1984 Buick Century T-Type uses lower-profile 195/70R14 and 215/60R14 radial sizes that stand apart from the rest of the Century range. Tire selection here is tied more closely to the car’s sporty visual character, so wheel setup and desired blackwall or raised white letter appearance should both be checked carefully.

Common 1984 Buick Century tire questions usually come down to exact sub-model fitment, 14-inch wheel compatibility, whitewall versus sport-style sidewalls, and how to choose among the Century’s taller touring sizes and T-Type performance-oriented options.
Tire Size & Fitment
What tire size fits a 1984 Buick Century?
The 1984 Buick Century uses four primary tire sizes: 195/75R14, 185/75R14, 195/70R14, and 215/60R14. The taller 185/75R14 and 195/75R14 sizes are used on Custom, Estate, Limited, and Olympia Limited models, while the T-Type uses the lower-profile 195/70R14 and 215/60R14 sizes.
The right choice depends on the exact sub-model and the wheel-and-tire combination already on the car. A Century that has been kept original, changed to another factory-accepted size, or fitted with replacement wheels can look similar at a glance, so checking the current wheel diameter and tire size before ordering is the safest approach.
What size rim does a 1984 Buick Century use?
The 1984 Buick Century uses 14-inch rims across all of its primary tire sizes. That applies whether the car is using 185/75R14, 195/75R14, 195/70R14, or 215/60R14, so the wheel diameter remains consistent even though the tire profiles and widths vary.
Wheel diameter is only one part of the fitment picture. Width can still matter, especially when comparing a narrower touring tire to a wider T-Type fitment, so it helps to confirm both the wheel size and the tire currently mounted before moving from one approved Century size family to another.
Do all 1984 Buick Century sub-models use the same tire size?
No, the 1984 Buick Century does not use one universal tire size across every sub-model. Diesel versions of the Custom, Estate, Limited, and Olympia Limited use 195/75R14, many gas versions use either 185/75R14 or 195/75R14, and the T-Type uses 195/70R14 or 215/60R14.
That means sub-model identification comes before product selection. A wagon, sedan, or T-Type may all share the Century name, but the tire character is different, from traditional whitewall touring radials to lower-profile sport-oriented options. Matching the tire to the exact model keeps the stance, clearance, and overall look within the right range.
Choosing the Right Tire
What should I consider when choosing a 1984 Buick Century tire?
Start with the exact tire size that belongs on the specific 1984 Buick Century sub-model, since this car uses several different 14-inch radial fitments. After size, the main differences are sidewall style, tire series, rim-width compatibility where stated, and whether the car is being kept in a traditional touring presentation or a sportier T-Type appearance.
A whitewall radial makes sense for many Custom, Estate, Limited, and Olympia Limited cars, while blackwall or raised white letter options better suit the T-Type fitments offered here. It also helps to compare load figures and wheel-width ranges when they are given, especially if the Century has replacement wheels or a setup that may differ from stock.
What sidewall styles are available for 1984 Buick Century tires?
Sidewall choices for the 1984 Buick Century include wide whitewall, narrow whitewall, blackwall, and RWL, which is raised white letter. The exact style depends on the tire size, with the touring-oriented 185/75R14 and 195/75R14 offerings centered on whitewall radials, while the T-Type sizes bring in blackwall and raised white letter options.
That gives the Century owner a clear appearance choice after the correct size is confirmed. Whitewalls support a more formal mid-1980s Buick look, while blackwall and raised white letter designs create a more performance-focused presentation. Sidewall style should follow both the sub-model and the overall character the car is meant to project.
What brands offer tires for the 1984 Buick Century?
Brands available for 1984 Buick Century tire sizes include Coker Classic, Tornel, Maxxis, Travelstar, Dunlop, and BFGoodrich. Brand availability changes by size, so the 195/75R14 and 185/75R14 touring sizes have the broadest whitewall selection, while the 195/70R14 and 215/60R14 T-Type sizes are tied to more specialized sport-oriented offerings.
Brand comparison is most useful after the correct fitment has been narrowed down. At that point, it becomes easier to compare sidewall treatment, tire series, stated rim-width range where available, and the overall look the tire gives the car. The best choice is usually the one that matches both the Century’s actual setup and its intended use.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Buick Century?
A period-style 1984 Buick Century usually starts with the proper sub-model tire size, then the sidewall treatment that best matches the car’s character. For many Custom, Estate, Limited, and Olympia Limited cars, that points toward 185/75R14 or 195/75R14 whitewall radials, while the T-Type’s 195/70R14 and 215/60R14 fitments support a sportier blackwall or raised white letter look.
Appearance should follow the exact version of the car rather than a one-style-fits-all approach. A formal Buick wagon and a T-Type project very different personalities, even though both are Century models. When exact originality matters, comparing the tire choice to period photos, build records, or marque-specific references is a smart final step.
How does tire construction affect the appearance of a restored 1984 Buick Century?
On the 1984 Buick Century, construction is straightforward because the primary fitments are radial. The visible difference comes less from bias-ply versus radial choice and more from sidewall style, profile, and tread presentation, such as whether the car wears a taller whitewall touring tire or a lower-profile blackwall or raised white letter design.
That means the restored look is shaped mainly by matching the tire size and sidewall treatment to the sub-model. A wide or narrow whitewall can give the car a softer, more upscale presentation, while the T-Type sizes bring in a noticeably sportier visual tone. Keeping the tire profile appropriate helps the car sit and look more like its era.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Buick Century?
Yes, modifications can affect tire fitment on a 1984 Buick Century, even though all of its primary sizes use a 14-inch wheel. Aftermarket wheels, different wheel widths, altered offset, suspension changes, or body modifications can change how a 185/75R14, 195/75R14, 195/70R14, or 215/60R14 tire sits in the wheel opening.
That matters most when moving between the Century’s taller touring sizes and the T-Type’s lower-profile options. A car that has been lowered or fitted with wider wheels should be checked for steering clearance, fender clearance, and overall wheel compatibility before a replacement tire is chosen, even when the size itself is one used on this model line.
What should I inspect before driving a 1984 Buick Century on new tires?
Before driving a 1984 Buick Century on new tires, inspect the wheels for correct diameter and condition, confirm that the tire size matches the sub-model, and check for adequate clearance at the fenders and steering components. It also helps to make sure the valve stems are sound and that inflation pressure is set appropriately for the tire being used.
A collector or lightly used Century can also have suspension, alignment, or brake issues that were easy to miss on old tires. Looking over tread seating, wheel fastener condition, and any signs of rubbing during the first short drive can prevent small fitment problems from becoming larger ones once the car is back on the road.
How should tires on a collector 1984 Buick Century be maintained?
Tires on a collector 1984 Buick Century should be checked regularly for pressure, visible cracking, bulges, cuts, uneven wear, and slow air loss. Even a well-kept car that sees only occasional use can develop age-related tire issues long before the tread appears worn, especially when the vehicle spends long periods parked.
Storage conditions play a big role in tire life. Keeping the Century away from prolonged sunlight, moisture, and ozone sources such as electric motors helps preserve both the rubber and the sidewall appearance. Regular inspections before drives and after long storage periods are especially important on cars using whitewall or specialty appearance-oriented tires.
