The 1997 Buick Century sits in the final years of Buick’s long-running midsize sedan tradition, offering the smooth, comfort-first character that made these cars a familiar sight in American driveways. Buyers looking after one today are often balancing practical road use with the desire to keep the car’s appearance in step with its late-1990s personality. Tire fitment is straightforward here, with 205/70R15 as the primary size on a 15-inch wheel and radial construction throughout. That still leaves meaningful choice, including blackwall, narrow whitewall, wide whitewall, and even a bias-look radial presentation. The right selection comes down to appearance, wheel compatibility, and how the car will actually be driven.
Which Tire Size Is Right for The 1997 Buick Century
The 1997 Buick Century uses one primary tire size: 205/70R15. It is a radial tire on a 15-inch rim, and that same fitment carries across the covered Century sub-models. With size settled, the real decision is which version of that size best suits the car, whether that means a traditional whitewall look, a blackwall presentation, or a radial option with a more vintage-inspired appearance.
205/70R15 is a metric radial size in which 205 identifies the nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 15 is the wheel diameter in inches. On the 1997 Buick Century, this is the core fitment and it matches the car’s modern suspension and everyday road-going character. Available choices within this size include blackwall, narrow whitewall, and wide whitewall styles from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. That gives Century owners room to choose between a cleaner late-model look, a more traditional Buick-style whitewall presentation, or a specialty radial with a different visual character.
Tire fitment is simple across the covered 1997 Buick Century sub-models, since both use the same primary size. Checking the exact sub-model still helps confirm that the wheel setup has not been changed over the years and keeps tire selection focused on style and product preference rather than size differences.

1997 Buick Century Custom
The 1997 Buick Century Custom uses the same 205/70R15 radial fitment as the other covered Century sub-model. That makes selection more about choosing the right sidewall style, brand, and tire series for the car’s appearance and intended road use than sorting through multiple primary sizes.
The 1997 Buick Century Limited also uses 205/70R15 radial tires on a 15-inch wheel. For this sub-model, the main decision is whether to keep a more formal whitewall presentation, choose a blackwall tire, or compare specialty radial options that change the car’s visual tone without changing the primary size.
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 1997 Buick Century?
The 1997 Buick Century uses 205/70R15 tires. This is the primary fitment for the covered Century models, and it is a radial size designed for a 15-inch wheel. Both the Century Custom and Century Limited use this same size, so the basic fitment question is straightforward on this vehicle.
That simplicity means the next step is not choosing between different primary sizes, but choosing the right version of 205/70R15. Before replacing tires, confirm that the car still has its correct 15-inch wheels and has not been changed to an aftermarket wheel package, since wheel diameter and width still matter even when the factory-size answer is clear.
What size rim does a 1997 Buick Century use?
The 1997 Buick Century uses a 15-inch rim with its 205/70R15 tire size. The tire size itself confirms the 15-inch wheel diameter, and the available tires in this fitment are built around that same rim diameter. That makes wheel diameter one of the simplest parts of Century tire selection.
Even so, wheel diameter is only part of the fitment picture. It is smart to verify the actual wheel on the car, especially if it has been owned by several people or has had replacement wheels installed over time. Rim width should also be checked against the tire being considered, since different 205/70R15 products can call for slightly different wheel-width ranges.
Do all 1997 Buick Century sub-models use the same tire size?
Yes. The covered 1997 Buick Century sub-models use the same 205/70R15 radial tire size. That includes both the Century Custom and Century Limited, so there is no split in primary tire size between those two versions of the car.
For most owners, that means sub-model identification is less important than confirming the car still wears the proper 15-inch wheels. Once that is settled, the decision shifts toward appearance and product details, such as whether a blackwall, narrow whitewall, or wide whitewall tire better matches the Century’s character and how the car is being preserved or driven.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1997 Buick Century?
Start with the correct size, which is 205/70R15, and make sure the tire matches the Century’s 15-inch wheel setup. From there, compare construction, sidewall appearance, brand, tire series, and any product details such as load figures or recommended rim-width range that matter to the way the car will be used.
A regularly driven Century may call for a different choice than one being kept for occasional fair-weather use or a more formal period-style presentation. Whitewall width, blackwall styling, and specialty radial designs can all change the car’s visual impression, so it helps to decide early whether the priority is everyday practicality, a traditional Buick look, or a more distinctive presentation.
What sidewall styles are available for 1997 Buick Century tires?
205/70R15 tires for the 1997 Buick Century are available in blackwall, narrow whitewall, and wide whitewall styles. That creates a useful spread of appearance choices, from a cleaner late-model look to a more traditional sidewall treatment that better suits the Century’s comfortable, upscale sedan character.
Sidewall choice affects appearance more than fitment, but it can make a noticeable difference in how the car reads at a glance. A blackwall often gives the Century a plainer modern-driver look, while narrow and wide whitewalls move it toward a more formal, restoration-minded presentation. Matching the sidewall to the wheel covers, trim, and the car’s intended use usually leads to the most satisfying result.
What brands offer tires for the 1997 Buick Century?
Brands available in 205/70R15 for the 1997 Buick Century include Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. Those options cover a mix of blackwall and whitewall radials, along with specialty offerings that give Century owners more than one way to stay within the correct size.
The practical way to compare them is by looking at the tire series, sidewall treatment, and wheel-width compatibility instead of assuming every 205/70R15 is the same. Brand choice should support the kind of Century being built or maintained, whether that means a clean driver, a comfort-oriented cruiser, or a more appearance-conscious sedan with period-style visual cues.
Restoration & Appearance
Which tire should I choose for a period-style 1997 Buick Century?
For a period-style 1997 Buick Century, the right starting point is still the correct 205/70R15 radial size on a 15-inch wheel. From there, the decision usually comes down to presentation, with narrow whitewall and wide whitewall options offering a more traditional Buick look than a plain blackwall tire.
The best visual choice depends on how the car is being preserved. A clean driver may look right on a modest whitewall, while a more formal restoration-minded Century may benefit from a wider whitewall treatment. When exact originality matters, it is worth checking period sales material, surviving original cars, or Buick enthusiast references before settling on a sidewall style.
How does tire construction affect the appearance of a restored 1997 Buick Century?
On a 1997 Buick Century, radial construction is already the natural fitment, so the visual difference comes less from switching construction types and more from choosing the tire’s sidewall treatment and overall design. In this size, blackwall, narrow whitewall, wide whitewall, and bias-look radial styling can all give the car a distinctly different presence.
That matters on a restored or carefully preserved Century because tires strongly influence the car’s stance and personality. A blackwall can make the car look more utilitarian, while whitewalls add a more formal Buick character. A bias-look radial can also change the presentation, but it should be evaluated carefully against wheel compatibility and the specific look being pursued.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 Buick Century?
Yes. Even though the 1997 Buick Century uses 205/70R15 as its primary tire size, modifications can change what works on an individual car. Aftermarket wheels, altered wheel width, suspension changes, lowering, or body repairs can all affect clearance, steering movement, and how a tire sits within the wheel opening.
That is why a Century with a non-original setup should be inspected before replacement tires are chosen. Checking actual wheel diameter and width, along with clearance at full steering lock and through suspension travel, is more useful than assuming every Century still matches its original configuration. A stock-size tire is the right reference point, but the car’s current hardware still needs confirmation.
What should I inspect before driving a 1997 Buick Century on new tires?
Before driving a 1997 Buick Century on new tires, inspect the wheels for damage, confirm the wheel diameter is still 15 inches, and make sure the new 205/70R15 tires match the wheel properly. It is also wise to check valve stems, tire pressure, lug hardware, and the overall condition of the suspension and steering components.
A fresh set of tires can only perform as well as the rest of the car allows. Uneven wear, loose front-end parts, weak shocks, or poor alignment can quickly spoil a new set and change how the Century feels on the road. A short local test drive, followed by a recheck of pressure and visual condition, is a sensible step before longer use.
How often should tires on a 1997 Buick Century be inspected?
Tires on a 1997 Buick Century should be inspected regularly, especially if the car is driven infrequently. Collector-age cars often spend long periods parked, which makes it important to watch for air loss, sidewall cracking, flat spotting, cuts, bulges, and uneven tread wear even when annual mileage is low.
A quick visual check before each drive is a good habit, with a more thorough inspection at regular service intervals and before longer trips. Tire pressure deserves special attention because a car that sits can lose pressure gradually without obvious warning. Keeping the Century clean, properly inflated, and stored away from prolonged heat, sunlight, and ozone sources helps extend tire life.
