The 1989 Buick Century sat in the heart of Buick’s front-wheel-drive midsize lineup, balancing practical family transportation with the cleaner, more aerodynamic styling that defined late-1980s American sedans and wagons. That makes tire choice on a 1989 Buick Century less about vintage bias-ply concerns and more about matching the right 14-inch radial size to the car’s actual setup. This model uses 185/75R14, 195/70R14, or 215/60R14 radial tires, depending on configuration and wheel choice. Available options range from narrow whitewall touring-style tires to blackwall and raised white letter performance-oriented choices. The key is confirming the exact size already on the car and choosing a tire that suits its appearance, intended use, and wheel dimensions.
Which Tire Size Is Right for The 1989 Buick Century
The 1989 Buick Century uses three primary tire sizes, all built as radial tires for 14-inch rims. Because the same sub-models can appear with more than one size, the first step is confirming the exact tire size already fitted to the car and verifying that the wheel width matches the tire being considered. Once that is settled, the decision becomes one of style, series, and intended driving character.
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 rim diameter in inches. On the 1989 Buick Century, this size represents a traditional 14-inch radial fitment with a touring-oriented profile. Available choices center on narrow whitewall presentation from Tornel, Maxxis, and Travelstar across the Tornel Classic, Classic Whitewall MA-1, and UN106 series. This size makes the most sense for an owner who wants a more classic late-1980s passenger-car look with whitewall styling on the correct rim diameter.
195/70R14 is a metric radial size that combines a 195-millimeter nominal section width, a 70-series profile, radial construction, and a 14-inch rim. For a 1989 Buick Century, it sits between the narrower 185-series fitment and the wider 215-series option while keeping the same wheel diameter. The available product in this size is a Dunlop Sport Classic with a blackwall sidewall, giving it a more understated and performance-flavored appearance than the whitewall alternatives. It is a useful size to evaluate when the car already carries this fitment and the goal is a clean, road-focused radial choice.
215/60R14 is a metric radial size where 215 is the nominal section width in millimeters, 60 is the aspect ratio, R denotes radial construction, and 14 indicates the rim diameter. On the 1989 Buick Century, this size brings a wider, lower-profile 14-inch radial fitment than the other two primary sizes. The available option is the BFGoodrich Radial T/A in the Radial TA series with raised white letter sidewalls, giving the car a more assertive period-style look. This size deserves careful wheel-width confirmation before selection, especially on cars that may no longer wear their original wheel setup.
Tire fitment across the 1989 Buick Century lineup is broad rather than sharply split by sub-model, since Custom, Estate Wagon, and Limited versions can all appear with the same three 14-inch radial sizes. Checking the exact sub-model still helps, but confirming the wheel and the tire size already on the vehicle matters even more.

1989 Buick Century Custom
The 1989 Buick Century Custom can use any of the three 14-inch radial sizes associated with this model line. That means tire selection should begin with the actual size mounted on the car, then move to appearance choices such as narrow whitewall, blackwall, or raised white letter styling.
The 1989 Buick Century Estate Wagon shares the same range of 14-inch radial tire sizes used elsewhere in the Century lineup. For wagon owners, the practical step is confirming the installed size and wheel dimensions before comparing available tire series, sidewall treatment, and load-related specifications.
The 1989 Buick Century Limited also falls within the same three-size, 14-inch radial fitment pattern. That gives the owner room to choose between a more conservative touring-style presentation and a sportier visual approach, provided the existing wheel and tire size are matched correctly.
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.
Best 1989 Buick Century Tires for Sale
Available 1989 Buick Century tire choices span 185/75R14, 195/70R14, and 215/60R14 radials from Tornel, Maxxis, Travelstar, Dunlop, and BFGoodrich.

Common questions for the 1989 Buick Century usually center on identifying the correct 14-inch radial size, understanding how the three fitments differ, and choosing between whitewall, blackwall, or raised white letter tire styles for the car’s intended use.
Tire Size & Fitment
What tire size fits a 1989 Buick Century?
A 1989 Buick Century uses one of three radial tire sizes: 185/75R14, 195/70R14, or 215/60R14. All three are 14-inch fitments, so the main difference is not wheel diameter but the tire’s width and profile. Those sizes appear across the Century lineup rather than being limited to just one clearly separate trim.
The practical step is to confirm the size already on the car before choosing a replacement. Door-jamb labeling, the existing tire sidewall, and the actual wheel setup should all agree. On an older Century, previous wheel or tire changes are common, so matching the replacement to the installed wheel width and overall clearance matters more than relying on trim name alone.
What size rim does a 1989 Buick Century use?
The 1989 Buick Century uses a 14-inch rim with the primary tire sizes covered here. That is consistent across 185/75R14, 195/70R14, and 215/60R14, so the key fitment difference is the tire size itself rather than a change in rim diameter from one option to another.
Rim diameter is only part of the fitment picture, though. Wheel width still needs to suit the tire being considered, especially when moving to a wider option such as 215/60R14. A Century that has replacement wheels, wheel covers hiding a different rim, or older service parts should be checked directly so the tire size and wheel dimensions work together properly.
Why does the 1989 Buick Century have more than one tire size?
The 1989 Buick Century appears with three different radial sizes because the model line could be equipped in more than one way while still using a 14-inch wheel. The available fitments include a taller-profile 185/75R14, a mid-range 195/70R14, and a wider, lower-profile 215/60R14.
That means the right replacement is the size that matches the car’s current wheel and tire setup, not simply the model name on the trunk. On a vehicle of this age, wheels may have been swapped over time for appearance or service reasons. Checking the tire sidewall, wheel width, and clearance around suspension and fenders helps avoid choosing the wrong size from an otherwise correct Century listing.
Choosing the Right Tire
What should I consider when choosing a 1989 Buick Century tire?
Start with the exact tire size on the car, since a 1989 Buick Century may use 185/75R14, 195/70R14, or 215/60R14. After size, the main considerations are sidewall style, tire series, and whether the vehicle is being kept in a more traditional touring presentation or given a sportier late-1980s look.
A narrow whitewall tire suits buyers who want a more formal period-style appearance, while blackwall and raised white letter options change the car’s visual character significantly. Rim-width compatibility also matters, particularly with wider sizes. Comparing load figures, construction details, and the way the car is actually driven will usually narrow the choice faster than focusing on appearance alone.
What sidewall styles are available for 1989 Buick Century tires?
Three sidewall styles are available across 1989 Buick Century tire options: narrow whitewall, blackwall, and RWL, which is raised white letter. Narrow whitewall choices appear in 185/75R14, blackwall appears in 195/70R14, and the 215/60R14 option uses a raised white letter presentation.
Those styles can change the car’s character even when wheel diameter stays the same. A narrow whitewall tends to support a more conservative Buick appearance, while blackwall looks cleaner and less formal. Raised white letter sidewalls give the Century a stronger period performance flavor, but that style comes with the wider 215/60R14 fitment, so wheel width and clearance deserve extra attention.
What brands offer tires for the 1989 Buick Century?
Tires for the 1989 Buick Century are available from Tornel, Maxxis, Travelstar, Dunlop, and BFGoodrich. Brand choice depends in part on tire size, since 185/75R14 has multiple options, while 195/70R14 and 215/60R14 each center on a single available brand and series combination.
That makes the buying process different depending on which size the car uses. An owner with 185/75R14 can compare several whitewall radials across different series, while the other two sizes are more tightly tied to a particular look and tire character. It helps to compare the actual product details that matter most for the car, such as sidewall style, rim-width suitability, weight, and load capacity.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Buick Century?
A period-style 1989 Buick Century usually starts with the tire size already correct for the car, then narrows the choice by appearance. In this group, 185/75R14 narrow whitewall radials create the most formal late-1980s Buick presentation, while 195/70R14 blackwall and 215/60R14 raised white letter options move the look in a sportier direction.
The best visual match depends on how the car is being restored or preserved. Some owners want a clean, family-sedan look, while others prefer a more assertive period personality. If exact originality matters, compare the tire choice against the car’s own historical references and current wheel setup rather than assuming any available sidewall treatment is automatically right for every Century.
How does tire construction affect the appearance of a restored 1989 Buick Century?
On a restored 1989 Buick Century, construction is less of an appearance issue than it would be on an older collector car because the primary fitments here are already radial tires. The visual difference comes more from the size and sidewall treatment than from choosing between bias-ply and radial construction.
That shifts attention to profile and sidewall presentation. A taller whitewall radial can give the car a more traditional Buick stance, while a lower-profile raised white letter tire looks more performance-oriented and less formal. Keeping the car visually consistent usually means choosing a tire that matches the wheel, the trim level’s character, and the owner’s restoration goals.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Buick Century?
Yes, modifications can affect tire fitment on a 1989 Buick Century even when the tire size looks correct on paper. Aftermarket wheels, altered wheel width, offset changes, suspension work, or body and fender repairs can all change how 185/75R14, 195/70R14, or 215/60R14 tires sit and clear the car.
That is especially important on the wider 215/60R14 size, where wheel-width suitability becomes more critical. A Century with replacement wheels should be checked at full steering lock and through suspension movement before settling on a tire. Older family cars are often changed over time, so the safest approach is to verify the actual hardware on the vehicle rather than assume it still matches original-type dimensions.
What should I inspect before driving a 1989 Buick Century on new tires?
Before driving a 1989 Buick Century on new tires, inspect the wheels for damage, confirm the tire size matches the car’s setup, and make sure inflation is set appropriately for the tire and vehicle application. Lug hardware, valve stems, and overall wheel condition should also be checked so the new tires are starting from a sound foundation.
A short road test should follow with attention to rubbing, vibration, pulling, or any unusual steering feel. It also helps to recheck pressure after the first miles and confirm that the tires clear the suspension and bodywork under normal driving conditions. On an older Century, worn steering or suspension parts can make a new set of tires feel worse than expected.
How often should tires on a 1989 Buick Century be inspected?
Tires on a 1989 Buick Century should be inspected regularly, especially if the car is driven infrequently or stored for long periods. Tread wear, cracking, bulges, cuts, and unexplained air loss all deserve attention. Collector-minded or lightly used late-1980s cars can look fine at a glance while still developing age-related tire problems.
A quick visual check before each drive and a more deliberate inspection at routine service intervals is a sensible habit. Pressure should be monitored consistently, and the sidewalls should be examined closely if the car has been parked for extended periods. Storage near heat, sunlight, or ozone sources can shorten tire life, so usage pattern matters almost as much as mileage.
