By 1999, the Buick Century had settled into its role as a comfortable midsize sedan aimed at quiet, dependable everyday driving. Its appeal today often comes from that same honest character, especially for owners preserving a well-kept original car or maintaining a clean late-1990s Buick as a usable classic. The 1999 Buick Century uses a 205/70R15 radial tire on a 15-inch rim, so the main decision is less about size and more about selecting the right style within that fitment. Available choices include blackwall, narrow whitewall, and wide whitewall designs across several radial series, with a bias-look radial also offered for a more traditional presentation.
Which Tire Size Is Right for The 1999 Buick Century
The 1999 Buick Century uses one primary tire size: 205/70R15. It is a radial fitment for a 15-inch rim, and both Century Custom and Century Limited models share that same size. That means the key choice is not between multiple factory fitments, but between available tire styles, brands, sidewall treatments, and whether a more traditional-looking radial suits the car's appearance goals.
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 the 1999 Buick Century, this is the standard fitment format and gives buyers a familiar modern sizing system that is easy to compare across replacement options. Within this size, choices include blackwall, narrow whitewall, and wide whitewall tires from brands such as Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. The right selection depends on whether the goal is everyday road use, a more upscale period-style look, or a traditional sidewall presentation that better suits the car.
Tire fitment is straightforward across the covered 1999 Buick Century sub-models because both use the same 205/70R15 radial size. Checking the exact sub-model still helps confirm that the car has retained its original wheel setup before comparing sidewall and brand options.

1999 Buick Century Custom
The 1999 Buick Century Custom uses the same 205/70R15 radial fitment as the rest of the Century range covered here. That keeps tire selection focused on appearance and product choice, including blackwall, narrow whitewall, wide whitewall, or a more traditional-looking radial presentation.
The 1999 Buick Century Limited also uses 205/70R15 radial tires on a 15-inch rim. For this sub-model, the decision centers on the style and character of the replacement tire rather than a different size, so wheel condition and preferred sidewall treatment become the main checks.
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 1999 Buick Century?
The 1999 Buick Century uses a 205/70R15 radial tire. That size applies to both the Century Custom and Century Limited, so there is one primary fitment to focus on rather than different sizes for different covered trims.
That makes the next step fairly simple: confirm the car still has 15-inch wheels and then compare the available tire styles within 205/70R15. If the car has aftermarket wheels or a previous owner changed the setup, verify the actual wheel diameter and width before choosing a replacement tire.
What size rim does a 1999 Buick Century use?
The 1999 Buick Century uses a 15-inch rim with its 205/70R15 tire size. The tire code itself confirms that wheel diameter, since the final number in 205/70R15 identifies the rim as 15 inches.
Wheel width still matters even when the diameter is correct, because different 205/70R15 tires are built around slightly different approved rim-width ranges. A Century that remains on its original-style wheel setup is usually straightforward, but any wheel swap should be checked carefully before selecting a tire.
Do all 1999 Buick Century sub-models use the same tire size?
Yes. Both the 1999 Buick Century Custom and the 1999 Buick Century Limited use the same 205/70R15 radial tire size. There is no split fitment here that forces a choice between two different primary sizes.
That consistency means buyers can spend more time comparing tire appearance and product character instead of sorting through trim-specific sizing differences. It is still smart to inspect the car's current wheels and tire markings, especially if the Century has spent years in secondhand ownership or has seen replacement wheels.
Choosing the Right Tire
What should I consider when choosing a 205/70R15 tire for a 1999 Buick Century?
Start with the basics: correct 205/70R15 sizing, radial construction, and a 15-inch wheel. From there, the real choice is between tire character and appearance, including blackwall, narrow whitewall, wide whitewall, and a range of brand and series options.
A well-preserved Buick Century can look very different depending on sidewall treatment, so appearance matters as much as fitment for many buyers. It also helps to compare rim-width compatibility, load figures where stated, and whether the car will be driven regularly or kept as a clean, lightly used survivor.
What sidewall styles are available for 1999 Buick Century tires?
205/70R15 tires for the 1999 Buick Century are available in blackwall, narrow whitewall, and wide whitewall styles. That gives the Century owner a meaningful visual choice, from a simple late-model replacement look to a brighter, more traditional presentation.
A blackwall usually suits a stock everyday appearance, while whitewall options can add more visual contrast and a stronger Buick character. The best choice depends on how the car is being presented, along with practical checks such as wheel condition, proper pressure, and enough clearance for the selected tire.
What brands offer tires for the 1999 Buick Century?
The 1999 Buick Century's 205/70R15 fitment is available from Maxxis, Michelin, Avon, American Classic, Coker Classic, Dunlop, Tornel, and Travelstar. Those options cover both straightforward replacement radials and more appearance-oriented choices within the same general size category.
Brand alone should not make the decision. Compare each tire's series, sidewall style, stated load information when available, and wheel-compatibility details so the tire suits both the car and the way it will be used. That approach matters more than chasing a name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1999 Buick Century?
For a period-style 1999 Buick Century, 205/70R15 remains the correct starting point because it preserves the car's intended overall sizing format and 15-inch wheel relationship. From there, a narrow whitewall or wide whitewall radial can create a more traditional Buick presentation than a plain blackwall.
The best match depends on whether the goal is a clean showroom-style sedan look or a more understated everyday appearance. Exact originality questions should be checked against vehicle-specific sales literature, surviving examples, or marque references, since sidewall treatment can vary from what simply looks appropriate on the car.
How does tire construction affect the appearance of a restored 1999 Buick Century?
The 1999 Buick Century is a radial-fitment car, so radial construction already aligns with the vehicle's era and general visual character. Appearance changes come more from sidewall style and tread presentation, although a bias-look radial can give the tire a more traditional look than a standard blackwall radial.
That distinction matters most on a carefully preserved or cosmetically restored Century where the wheel-and-tire package has a strong effect on the car's stance and personality. Buyers chasing a cleaner late-1990s sedan look may prefer blackwalls, while whitewalls can bring out a more classic Buick feel.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1999 Buick Century?
Yes. A 1999 Buick Century may be associated with 205/70R15 tires, but wheel changes, altered suspension height, or body modifications can change how that size behaves on the car. Even the correct nominal size can become a problem if the wheel width or offset has been changed.
A careful check should include actual wheel diameter, wheel width, and visible clearance around the fenders and steering components. That matters most on older used cars, where prior owners may have changed parts over time. Confirming the current setup prevents a simple tire replacement from turning into a fitment issue.
What should I inspect before driving a 1999 Buick Century on new tires?
Before putting a 1999 Buick Century back into regular road use on new tires, inspect the wheels for damage or corrosion, verify proper air pressure, and make sure the tires seat correctly and hold air. A quick look at alignment wear and basic suspension condition is also worthwhile.
Collector and low-use cars often need more than fresh rubber, especially if they have sat for long periods. Check for cracked valve stems, loose lug hardware, brake drag, and any rubbing during full-lock steering. A short test drive followed by another visual inspection helps catch small problems before they become larger ones.
How often should tires on a 1999 Buick Century be inspected?
Tires on a 1999 Buick Century should be inspected regularly, not just when tread appears worn. Look over them before longer drives and at routine intervals for pressure loss, uneven wear, sidewall cracking, bulges, cuts, or signs that the car has been sitting too long on underinflated tires.
A well-kept Century may not accumulate many miles, which makes age and storage conditions especially important. Cars stored near heat, sunlight, or ozone-producing equipment can age tires faster than expected. Regular inspection is the best way to catch condition issues early, even when the tread still looks usable.
