The 2000 Buick Century belongs to the final years of a long-running midsize Buick formula built around quiet road manners, everyday comfort, and clean, conservative styling. For many owners, it sits in the practical modern-classic space where originality matters, but dependable road use matters just as much. This exact car uses a 205/70R15 radial tire on a 15-inch rim, which keeps tire selection straightforward across the model line. Available choices include blackwall, narrow whitewall, and wide whitewall designs across several radial series, including a bias-look radial option. The real decision is matching the right appearance, construction style, and rim compatibility to the way the car is actually driven.
Which Tire Size Is Right for The 2000 Buick Century
The 2000 Buick Century uses one primary tire size: 205/70R15. It is a radial fitment on a 15-inch rim, and both the Custom and Limited use the same size, so the main choice is not size selection but choosing the right tire style, brand, and overall presentation for the car.
In 205/70R15, the 205 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. That makes it a modern metric radial format well suited to a 2000 Buick Century, which uses radial construction rather than an earlier bias-ply setup. Within this size, there are blackwall, narrow whitewall, and wide whitewall choices from brands including Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. The right choice depends on whether the goal is a stock-looking daily driver, a more traditional whitewall presentation, or a sportier blackwall appearance.
Tire fitment is straightforward across the covered 2000 Buick Century sub-models because both use the same primary size and radial construction. Checking the exact sub-model still helps confirm that the car remains on its original wheel setup before choosing among the available tire styles.

2000 Buick Century Custom
The 2000 Buick Century Custom uses the same 205/70R15 radial tire size as the rest of the model range covered here. That keeps tire selection focused on sidewall style, brand, and rim-width compatibility rather than sorting through multiple fitment sizes.
The 2000 Buick Century Limited also uses 205/70R15 radial tires on a 15-inch rim. For this sub-model, the buying decision is mainly about whether the car looks best on blackwalls, narrow whitewalls, or a wider whitewall treatment.
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 2000 Buick Century?
The 2000 Buick Century uses a 205/70R15 radial tire. That is the primary size for both the Custom and Limited sub-models, so the basic fitment is consistent across the covered Century lineup.
Since there is one main size, the decision usually comes down to sidewall style, brand, and the wheel setup actually on the car. It is still smart to confirm that the Century has its original 15-inch wheels and has not been changed to an aftermarket diameter or width before selecting a replacement tire.
What size rim does a 2000 Buick Century use?
The 2000 Buick Century uses a 15-inch rim with its 205/70R15 tire size. The tire size itself confirms that rim diameter, since the final number in the size code is the wheel diameter in inches.
Rim diameter is the first thing to verify before replacing tires, especially on an older used car that may have had wheel changes over time. After confirming 15-inch wheels, compare the wheel width to the tire's approved rim-width range so the tire's shape, clearance, and road behavior stay within an appropriate setup.
Do all 2000 Buick Century sub-models use the same tire size?
Yes. Both the 2000 Buick Century Custom and the 2000 Buick Century Limited use the same 205/70R15 radial tire size. That makes fitment simpler than on vehicles where trim level or package changes affect tire size.
Shared sizing does not mean every Century still has the same wheel setup it left with years ago. A previous owner could have changed wheels, added aftermarket rims, or altered ride height, so it is still worth checking actual wheel diameter, wheel width, and fender clearance before mounting new tires.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 2000 Buick Century?
Start with the correct 205/70R15 size and confirm that the tire is suitable for the 15-inch wheel on the car. From there, compare radial versus bias-look radial construction, sidewall style, approved rim-width range, and load figures when they are stated.
The Century can wear very different visual treatments even within the same size, from blackwall to narrow whitewall to wide whitewall. That means the right choice depends on whether the car is being kept close to its original everyday look, dressed with a more traditional Buick appearance, or set up for a more performance-oriented presentation.
What sidewall styles are available for 2000 Buick Century tires?
The 2000 Buick Century's 205/70R15 size is available in several sidewall styles, including blackwall, narrow whitewall, and wide whitewall. That gives the car a wide range of possible visual character without changing the primary tire size.
Blackwalls suit a more understated or sport-oriented look, while whitewall choices lean more traditional and formal, which often fits a Buick sedan well. Since sidewall treatment changes the car's overall presentation so noticeably, many owners narrow the tire search by appearance first and then compare brand, series, and wheel compatibility within that style.
What brands offer tires for the 2000 Buick Century?
The 2000 Buick Century's 205/70R15 fitment is available from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. Those brands cover blackwall, whitewall, and specialty-style options within the same basic size range.
Brand choice should be treated as one part of the decision rather than the whole decision. It helps to compare each tire's series, sidewall treatment, construction type, and wheel-width compatibility so the final selection suits the car's appearance goals and the way it will actually be driven.
Restoration & Appearance
Which tire should I choose for a period-style 2000 Buick Century?
A period-style 2000 Buick Century usually starts with the correct 205/70R15 size and then narrows down by sidewall treatment. Narrow whitewall and wide whitewall radials create a more traditional Buick presentation, while blackwalls give the car a more understated late-model sedan look.
The right appearance depends on how closely the car is being preserved and what visual era the owner wants to emphasize. For a restoration-oriented Century, matching the size first and then choosing the sidewall that best suits the car's trim, wheel covers, and overall presentation is usually the most useful approach.
How does tire construction affect the appearance of a restored 2000 Buick Century?
On a restored 2000 Buick Century, construction affects appearance mostly through the tire's overall presentation rather than through old-style bias-ply proportions. Standard radial choices keep a familiar modern shape, while a bias-look radial can give the car a slightly more traditional visual character without changing to an actual bias-ply tire.
That distinction matters most when appearance is being balanced against everyday drivability. Owners aiming for a clean restoration-style look often compare construction together with sidewall style, because a whitewall radial and a blackwall bias-look radial can create very different impressions even though both remain within the same general size family.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2000 Buick Century?
Yes, modifications can affect tire fitment on a 2000 Buick Century even though the original size is straightforward. Aftermarket wheels, altered wheel width, suspension changes, lowering, and body or brake modifications can all change how a 205/70R15 tire sits and clears.
A Century that has been changed from its original setup should be checked at full steering lock and through suspension travel before assuming the tire choice is settled. Verifying actual wheel diameter, wheel width, and nearby clearance points matters more on a modified car than simply matching the original size code.
What should I inspect before driving a 2000 Buick Century on new tires?
Before driving a 2000 Buick Century on new tires, inspect wheel condition, confirm proper inflation, and check for any signs of suspension or alignment problems that could affect tire wear. It also helps to make sure the tires are seated correctly and that there is no rubbing at the front or rear.
A short initial drive is a good time to listen for vibration, contact noise, or pulling that may point to wheel, alignment, or clearance issues. Rechecking pressure after installation and looking over the sidewalls and tread after the first few trips helps catch problems before the car returns to regular road use.
How should 205/70R15 tires on a collector 2000 Buick Century be maintained?
Collector-use 205/70R15 tires on a 2000 Buick Century should be kept at the correct pressure, inspected regularly for cracking, bulges, cuts, uneven wear, and slow air loss, and protected from long periods of heat, sunlight, and ozone exposure. Low-mileage cars still need tire checks even when tread looks good.
A Century that spends long periods parked benefits from periodic movement so one part of the tire does not carry the same load continuously. Regular visual inspections, pressure checks, and attention to overall tire age are especially important on lightly used collector cars that may look ready for the road before the tires actually are.
