The 1998 Buick Century sits squarely in the final years of Buick’s traditional midsize front-wheel-drive sedan formula, built for quiet daily use rather than overt performance. That makes tire choice especially important, because the right fitment helps preserve the Century’s composed ride and familiar road manners. This model uses a 205/70R15 radial tire on a 15-inch rim, and that same primary size carries across the covered Century sub-models. Within that size, choices include blackwall, narrow whitewall, wide whitewall, and even a bias-look radial presentation across several brands and tire series. The key is matching the tire’s look and character to how the car is driven and maintained today.
Which Tire Size Is Right for The 1998 Buick Century
The 1998 Buick Century uses one primary tire size: 205/70R15, and it is a radial fitment for a 15-inch wheel. Both the Custom and Limited use this same size, so the main decision is not which primary size fits, but which version of that size best suits the car’s appearance, driving use, and wheel setup.
A 205/70R15 tire uses a 205-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 15-inch rim diameter. On a 1998 Buick Century, this modern metric radial format matches the car’s original-era tire sizing language and supports a straightforward replacement search. Available choices in this size include blackwall, narrow whitewall, wide whitewall, and bias-look radial styling from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. That makes 205/70R15 the size to evaluate when balancing traditional Buick appearance, road use, and wheel compatibility.
Tire fitment is straightforward across the covered 1998 Buick Century sub-models because they share the same primary tire size. Checking the exact sub-model still helps confirm that the car remains on its intended wheel setup before comparing whitewall, blackwall, or bias-look radial choices.

1998 Buick Century Custom
The 1998 Buick Century Custom uses the same 205/70R15 radial fitment as the other covered Century configuration. That keeps tire selection focused on appearance and product character, such as narrow whitewall, wide whitewall, blackwall, or a bias-look radial option.
The 1998 Buick Century Limited also uses the 205/70R15 radial size on a 15-inch wheel. For this sub-model, the decision centers on choosing the right sidewall presentation and tire series while confirming the car still has the correct wheel diameter and compatible rim width.
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 1998 Buick Century?
The 1998 Buick Century uses a 205/70R15 radial tire. That is the primary tire size for both covered sub-models, so the core fitment remains consistent whether the car is a Custom or a Limited.
The practical next step is confirming that the car still has 15-inch wheels and a compatible wheel width before choosing among the available tires in this size. Many Century sedans remain original, but aftermarket wheels or older replacement rims can change what works comfortably in terms of profile, appearance, and clearance.
What size rim does a 1998 Buick Century use?
The 1998 Buick Century uses a 15-inch rim with its 205/70R15 tire size. That 15-inch diameter is the key wheel measurement tied to the Century’s primary tire fitment.
Rim diameter should be checked first at the wheel itself, especially on a car that may have seen replacement wheels over time. After confirming 15-inch diameter, compare the wheel width against the tire you are considering, since available 205/70R15 products can carry different rim-width recommendations depending on brand and tire series.
Do all 1998 Buick Century sub-models use the same tire size?
Yes. The covered 1998 Buick Century sub-models use the same 205/70R15 radial tire size. Both the Custom and Limited share that primary fitment, so there is no split in size between those two versions.
That makes shopping simpler, because the decision shifts away from size differences and toward sidewall style, brand, construction details, and intended use. Even so, it is still wise to confirm the actual wheels on the car, because a Century with replacement rims may need closer attention to wheel width and overall tire presentation.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1998 Buick Century?
Start with the correct 205/70R15 size and a tire that matches the Century’s 15-inch wheel. From there, the meaningful differences are sidewall style, tire series, construction details, rim-width compatibility, and load information where it is stated.
A Buick Century often looks very different on a blackwall than it does on a narrow or wide whitewall, so appearance matters as much as fitment for many owners. It also helps to think about how the car is used, whether it is a regularly driven sedan, a preserved original, or a nostalgic cruiser that benefits from a more traditional sidewall treatment.
What sidewall styles are available for 1998 Buick Century tires?
The 1998 Buick Century has 205/70R15 tire choices in blackwall, narrow whitewall, and wide whitewall styles. A bias-look radial option is also available in blackwall form for buyers who want a more traditional visual character in a radial construction.
Sidewall choice changes the car’s presentation more than many owners expect. A blackwall tends to keep the look understated and contemporary to later replacement tires, while narrow and wide whitewalls move the Century toward a more formal, Buick-style appearance that many restoration-minded or nostalgic owners prefer.
What brands offer tires for the 1998 Buick Century?
Tires for the 1998 Buick Century in 205/70R15 are available from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. Those options cover both traditional-looking whitewall choices and sportier or more understated blackwall selections.
Brand alone should not be the only deciding factor. It makes more sense to compare the specific tire series, sidewall treatment, construction, wheel-width guidance, and load figures that matter for the way the Century is driven. That approach helps narrow the field without assuming every 205/70R15 tire serves the same purpose.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Buick Century?
A period-style 1998 Buick Century usually starts with the correct 205/70R15 size, then narrows the choice by sidewall appearance. Narrow whitewall and wide whitewall radials both suit the Century’s late-1990s Buick character differently, while a blackwall keeps the look more understated.
The best visual match depends on how original the car is and what kind of presentation is intended. Owners pursuing a highly authentic restoration should compare surviving photos, window stickers, dealer literature, or marque-specific references, since a tire’s correct size does not automatically make every available sidewall treatment historically exact.
How does tire construction affect the appearance of a restored 1998 Buick Century?
On a restored 1998 Buick Century, construction affects appearance mostly through tread and sidewall presentation rather than through a change in primary fitment, because 205/70R15 is already a radial size. Standard radial choices and a bias-look radial can give the car noticeably different visual character.
That means construction choice can be part of the styling decision as well as the fitment decision. A conventional radial usually aligns with a later-1990s replacement-tire look, while a bias-look radial introduces a more nostalgic presentation. Either way, the wheel diameter and tire size still need to remain appropriate for the car’s actual setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Buick Century?
Yes. A 1998 Buick Century may use the correct 205/70R15 tire size from the factory-style fitment standpoint, but wheel changes, suspension alterations, or body modifications can change how that tire sits and clears the car.
A Century with aftermarket wheels should have wheel width and diameter checked carefully before a tire is selected. Suspension sag, lowering, or non-stock offsets can also affect steering and fender clearance, so the safest approach is to confirm the actual wheel-and-body setup on the car rather than assuming every 205/70R15 will behave the same way.
What should I inspect before driving a 1998 Buick Century on new tires?
Before driving a 1998 Buick Century on new tires, inspect the wheels for damage, confirm the wheel diameter is 15 inches, and make sure the tires are properly seated and inflated. It also helps to check alignment condition and general suspension health on an older sedan.
A short visual review after installation can prevent avoidable problems. Look for sidewall contact, uneven clearance, vibration, and any sign that the car is sitting unusually low at one corner. Older Centurys that have spent time parked should also have brake condition, wheel fastener torque, and air retention checked before regular road use.
How should 205/70R15 tires on a collector 1998 Buick Century be maintained?
Collector-use 205/70R15 tires on a 1998 Buick Century should be kept at proper inflation, inspected for cracking, bulges, cuts, and uneven wear, and checked regularly even if the car is driven only occasionally. Low annual mileage does not stop tires from aging.
Storage conditions matter just as much as mileage on a preserved Century. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the rubber, and moving or driving the car periodically can help avoid long-term flat spotting. Any tire showing age-related deterioration deserves attention before the next road outing.
