The 1982 Buick Century sits at an interesting point in Buick history, bridging traditional midsize comfort with the more efficient, downsized thinking that defined many early 1980s American cars. For owners today, tire selection is less about bias-ply versus radial conversion and more about sorting out which of the two 13-inch radial sizes belongs on the car. The 1982 Buick Century uses either 185/80R13 or 205/70R13, and both sizes open different appearance and product choices, from whitewall touring-style radials to a blackwall performance-oriented option. The key is confirming the car's exact setup first, then matching tire size, sidewall style, and overall presentation to the way the Century will be driven and shown.
Which Tire Size Is Right for The 1982 Buick Century
The 1982 Buick Century uses two primary tire sizes, and both are radial tires built for 13-inch rims. Because both the Custom and Limited can use either size, the first step is confirming which size is currently on the car or which wheel-and-tire setup the vehicle is meant to use. Once size is confirmed, the decision shifts to sidewall appearance, tire series, and the overall look you want from a period-minded replacement.
185/80R13 is a metric radial size in which 185 identifies the nominal section width in millimeters, 80 is the aspect ratio, R means radial construction, and 13 is the wheel diameter in inches. On a 1982 Buick Century, this size supports a more traditional passenger-car presentation on a 13-inch rim. Available choices include Maxxis, BFGoodrich, and Coker Classic options, with narrow whitewall and wide whitewall styles offered across series such as Maxxis Radial, Silvertown Radial, and Star Series. This size is worth considering when maintaining a softer, more classic visual profile matters as much as basic fitment.
205/70R13 is also a metric radial size, with 205 indicating nominal section width in millimeters, 70 representing the aspect ratio, and 13 showing the wheel diameter in inches. For the 1982 Buick Century, it remains a 13-inch radial fitment but shifts to a wider, lower-profile format than 185/80R13. The available product in this size is a Michelin blackwall tire from the XDX-B series, giving it a distinctly different character from the whitewall options offered in the narrower size. This size deserves a careful look when the car's existing wheel setup and intended appearance point toward that wider radial profile.
Tire fitment on the 1982 Buick Century is straightforward in one sense, because both covered sub-models use the same two radial size options. Checking the exact sub-model still helps keep the purchase focused on the car's intended setup, current wheels, and desired appearance.

1982 Buick Century Custom
The 1982 Buick Century Custom can use either of the two 13-inch radial tire sizes associated with this model line. That makes selection less about trim distinction and more about confirming which wheel-and-tire combination is actually on the car before choosing between whitewall and blackwall product styles.
The 1982 Buick Century Limited also uses the same 13-inch radial fitment choices found on the Custom. With size overlap across the sub-models, the practical decision comes down to verifying the car's current tire size and then choosing the sidewall presentation and tire series that best suit the vehicle.
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 1982 Buick Century Tires for Sale
Available 1982 Buick Century tires span distinct visual directions: 185/80R13 choices from Maxxis, BFGoodrich, and Coker Classic in narrow or wide whitewall styles, and a 205/70R13 Michelin XDX-B blackwall option. That gives buyers a useful comparison between classic-looking whitewall radials and a more understated blackwall presentation.
Owners of a 1982 Buick Century usually need clarity on the two 13-inch radial sizes, sub-model fitment overlap, sidewall choices, and what to inspect before putting a collector-era Buick back on the road.
Tire Size & Fitment
What tire size fits a 1982 Buick Century?
The 1982 Buick Century uses two primary tire sizes: 185/80R13 and 205/70R13. Both are radial tire fitments for 13-inch wheels, and both the Custom and Limited sub-models can use either size depending on the vehicle's setup.
That means the real task is confirming which size belongs on the specific car in front of you. Check the current tires, wheel size, and overall stance before choosing, because 185/80R13 and 205/70R13 are not the same profile even though they share the same rim diameter.
What size rim does a 1982 Buick Century use?
The tire fitments associated with the 1982 Buick Century use a 13-inch rim diameter. Both 185/80R13 and 205/70R13 are built around that same 13-inch wheel size, so the rim diameter stays consistent across the supported tire options.
Rim diameter is only part of the fitment picture, so it is still wise to confirm wheel width before buying. The available tires in these sizes do not share the same rim-width ranges, and an aftermarket wheel can change what works cleanly on the car.
Do all 1982 Buick Century sub-models use the same tire size?
The 1982 Buick Century Custom and Limited share the same tire-size choices. Both sub-models can use either 185/80R13 or 205/70R13, so fitment does not split by sub-model name alone in this application.
Even with that overlap, the right purchase still depends on the car's actual wheel-and-tire setup. A Century that is currently on 185/80R13 whitewalls calls for a different buying decision than one already set up with 205/70R13 blackwalls on the same 13-inch diameter.
Choosing the Right Tire
What should I consider when choosing a tire for a 1982 Buick Century?
Start with the correct primary size, because the 1982 Buick Century uses either 185/80R13 or 205/70R13 on 13-inch wheels. After size is confirmed, compare construction details, rim-width compatibility, sidewall style, and the tire series available within that exact fitment.
Appearance matters on a car from this era, so the decision often comes down to how traditional or understated you want the Century to look. A whitewall radial gives a very different visual result than a blackwall tire, even when both are valid choices for the vehicle.
What sidewall styles are available for 1982 Buick Century tires?
Sidewall options for the 1982 Buick Century include narrow whitewall, wide whitewall, and blackwall styles. The 185/80R13 size carries the whitewall choices, while the 205/70R13 option is offered as a blackwall Michelin radial.
That makes sidewall style one of the biggest visual decisions on this car. Owners aiming for a more traditional Buick presentation often focus on the whitewall options, while a blackwall tire creates a plainer, more restrained look that still needs to match the car's confirmed tire size.
What brands offer tires for the 1982 Buick Century?
Tires for the 1982 Buick Century are available from Maxxis, BFGoodrich, Coker Classic, and Michelin. Brand availability depends on the tire size, with multiple choices in 185/80R13 and a Michelin option in the 205/70R13 fitment.
Brand should be considered alongside tire series, sidewall treatment, and wheel compatibility rather than as a stand-alone decision. It helps to narrow the search by confirming size first, then comparing the visual style and specifications that matter most for the way the Century will be used.
Restoration & Appearance
Which tire should I choose for a period-style 1982 Buick Century?
A period-style direction for a 1982 Buick Century usually begins with choosing the tire size that matches the car's established setup, then selecting the sidewall style that suits the Buick's character. In this application, 185/80R13 offers narrow whitewall and wide whitewall radial choices that create a more traditional presentation.
That does not automatically make every whitewall the exact original visual treatment for every car, so buyers focused on strict restoration should compare against build documentation or marque-specific reference material. For many owners, though, the right whitewall radial simply helps the Century look appropriately at home in its early 1980s setting.
How does tire construction affect the appearance of a restored 1982 Buick Century?
On a 1982 Buick Century, construction is less of a visual dividing line than on earlier bias-ply-era cars because the primary fitments are already radial. The bigger appearance difference comes from size and sidewall treatment, especially the contrast between 185/80R13 whitewall options and the 205/70R13 blackwall alternative.
A restored car aimed at a softer, more formal Buick look may read very differently depending on whether it wears a wide whitewall or a blackwall tire. Matching that visual tone to the car's trim, stance, and intended presentation is often just as important as selecting the right radial size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1982 Buick Century?
Yes, modifications can affect tire fitment on a 1982 Buick Century even when the car still uses a 13-inch wheel. Changes such as aftermarket wheels, altered wheel width, suspension work, or ride-height changes can influence which of the two supported tire sizes works best on the vehicle.
A Century that has been lowered or fitted with different wheels deserves a closer clearance check at the fenders, steering range, and suspension. That is especially important when choosing between 185/80R13 and 205/70R13, since the sizes differ in width and profile even though they share the same rim diameter.
What should I inspect before driving a 1982 Buick Century on new tires?
Before driving a 1982 Buick Century on new tires, inspect the wheels for the correct 13-inch diameter and suitable width, then confirm the tires are inflated properly and seated correctly. It is also smart to check for suspension wear, loose steering components, and any signs of previous rubbing.
A collector-era car can hide problems that only appear once it is back on the road. Looking over brake condition, alignment behavior, and fender clearance during a short initial drive helps catch issues early, especially if the Century has sat for long periods or has changed wheel-and-tire combinations over time.
How should tires on a collector 1982 Buick Century be maintained?
Tires on a collector 1982 Buick Century should be checked regularly for air loss, sidewall cracking, bulges, cuts, and uneven tread wear. Cars that are driven infrequently still need periodic inspection, because age and storage conditions can affect tire condition even when mileage stays low.
Storage habits matter almost as much as driving habits on an older Buick. Keeping the car away from prolonged sunlight, excess moisture, and ozone sources helps protect the tires, and moving the vehicle occasionally can reduce flat-spotting during long periods between drives.
