The 1979 Buick Century came from a period when Buick intermediates balanced traditional comfort with a leaner late-1970s footprint, making tire selection more about exact configuration than broad one-size-fits-all assumptions. Coupe, V6, and wagon versions can follow different fitment paths even though they share the same 14-inch wheel diameter. This Century uses radial tires in 205/70R14, 185/75R14, or 195/75R14 depending on sub-model. Available choices range from narrow and wide whitewalls to redline, dual redline, raised white letter, and blackwall designs across several series and brands. The right pick depends on whether the goal is stock-looking road use, a more sporting appearance, or a wagon or V6 fitment check before replacement.
Which Tire Size Is Right for The 1979 Buick Century
Three tire sizes apply to the 1979 Buick Century, and the correct choice depends on the exact sub-model rather than a change in wheel diameter, since all three sizes use a 14-inch rim. The first step is confirming whether the car is a Sport Coupe, V6, or Wagon. After that, the decision shifts to profile, appearance, and the available radial tire options within the correct size.
A 205/70R14 uses a 205-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 14-inch rim. On the 1979 Buick Century, this is one of the radial fitments used on specific sub-models and it carries the more performance-oriented look of the three primary sizes. Product choices in this size span Maxxis, BFGoodrich, and Michelin, with sidewall styles including narrow whitewall, redline, dual redline, raised white letter, and blackwall across series such as Classic Whitewall MA-1, Silvertown Radial, Radial TA, and XWX. It is the size to evaluate when the car already uses this lower-profile 14-inch setup.
A 185/75R14 uses a 185-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 14-inch rim. For the 1979 Buick Century, this size appears on V6 applications and reflects a narrower metric radial format than the other primary fitments. Available choices center on traditional narrow whitewall presentation from Tornel, Maxxis, and Travelstar in series such as Tornel Classic, Classic Whitewall MA-1, and UN106. This size makes the most sense when the vehicle calls for the narrower V6 fitment and the goal is a straightforward road-ready radial with a period-style sidewall treatment.
A 195/75R14 uses a 195-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 14-inch rim. On the 1979 Buick Century, it serves as one of the fitments for V6 and wagon applications, sitting between the narrower 185 width and the lower-profile 205/70 format. Choices include Coker Classic, Tornel, Maxxis, and Travelstar, with both narrow whitewall and wide whitewall options in series such as Star Series, Coker Classic Radial, Tornel Classic, Classic Whitewall MA-1, and UN106. It is a useful size to consider when appearance matters as much as fitment, especially for a more traditional whitewall presentation.
Sub-model fitment matters on the 1979 Buick Century because the covered versions do not all share the same tire size. Confirming whether the car is a Sport Coupe, V6, or Wagon is the key first step before comparing sidewall style, series, or brand choices.

1979 Buick Century Sport Coupe
The 1979 Buick Century Sport Coupe uses the 205/70R14 radial fitment. That makes the tire decision more about choosing the right look within that size, whether that means whitewall, redline, raised white letter, or a simpler blackwall presentation on the existing 14-inch wheel setup.
The 1979 Buick Century V6 uses either 185/75R14 or 195/75R14 radial tires, so exact configuration matters before replacement. Once the correct size is confirmed, the next decision is whether the car suits a narrower whitewall look or a broader set of appearance choices available in 195/75R14.
The 1979 Buick Century Wagon uses either 195/75R14 or 205/70R14 radial tires. That means wheel and existing tire setup should be verified before ordering, especially if the wagon has changed hands over the years or has already been fitted with replacement tires that differ in profile and sidewall style.
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 1979 Buick Century?
The 1979 Buick Century uses three possible tire sizes: 205/70R14, 185/75R14, and 195/75R14. The Sport Coupe uses 205/70R14, the V6 uses 185/75R14 or 195/75R14, and the Wagon uses 195/75R14 or 205/70R14. All of these are radial tires built for a 14-inch rim.
The practical step is confirming the exact sub-model and checking the size already mounted on the car before choosing a replacement. On a vehicle of this age, prior owners may have changed tire sizes, so matching the current wheel setup and confirming clearance is just as important as knowing the general Century fitment range.
What size rim does a 1979 Buick Century use?
The covered tire fitments for the 1979 Buick Century all use a 14-inch rim diameter. That applies across 205/70R14, 185/75R14, and 195/75R14, so the difference between these sizes is not wheel diameter but tire width and profile within the same 14-inch family.
That shared rim diameter simplifies part of the fitment process, but it does not mean every 14-inch tire is automatically suitable. Rim width, the exact sub-model, and the tire size already on the car still need to be checked, especially if the Buick has aftermarket wheels or a different stance than it originally carried.
Why does the 1979 Buick Century have more than one tire size?
The 1979 Buick Century has more than one tire size because fitment varies by sub-model. The Sport Coupe, V6, and Wagon do not all use the same radial size, even though they stay within the same 14-inch rim diameter. That creates separate fitment paths within the same year, make, and model family.
For a buyer, that means the car should be identified beyond just year and model name before ordering tires. A wagon may not use the same profile as a V6 sedan-style application, and the easiest way to avoid a mismatch is to confirm the sub-model, inspect the wheel setup, and compare the mounted tire size on the vehicle.
Choosing the Right Tire
What should I consider when choosing a 1979 Buick Century tire?
Start with the correct size for the exact 1979 Buick Century sub-model, since this car can use 205/70R14, 185/75R14, or 195/75R14. From there, compare radial construction details such as rim-width compatibility, load figures where shown, and the type of appearance you want, from understated blackwall to restoration-oriented whitewall or redline styling.
A good choice matches both the car and its intended use. A Century driven casually to shows may place more emphasis on sidewall appearance, while a road-driven car may call for a different series or specification range. Keeping the correct size first prevents appearance preferences from leading to the wrong fitment.
What sidewall styles are available for 1979 Buick Century tires?
Sidewall choices for the 1979 Buick Century include narrow whitewall, wide whitewall, redline, dual redline, raised white letter, and blackwall, depending on tire size. The broadest mix appears in 205/70R14, while 185/75R14 centers on narrow whitewall options and 195/75R14 adds both narrow and wide whitewall choices.
That variety lets the tire change the personality of the car even when the size stays correct. A wide whitewall can lean more traditional, a redline or raised white letter look can feel sportier, and a blackwall can keep the presentation simple. The key is choosing the look within the exact size your Century actually uses.
What brands offer tires for the 1979 Buick Century?
Brands available across the 1979 Buick Century fitments include Maxxis, BFGoodrich, Michelin, Coker Classic, Tornel, and Travelstar. Brand availability varies by size, so 205/70R14, 185/75R14, and 195/75R14 do not all carry the same mix of names, sidewall treatments, or tire series.
Brand choice is most useful after the correct size is settled. At that point, compare each option by sidewall style, series character, rim-width specification, and any visible load or speed-related details that matter to your use. The strongest comparison is not brand alone, but how each available tire fits the Buick and the look you want.
Restoration & Appearance
Which tire should I choose for a period-style 1979 Buick Century?
A period-style 1979 Buick Century tire starts with the correct sub-model size, then moves to the sidewall treatment that suits the car's presentation. Narrow whitewall options are available in all three primary sizes, while 195/75R14 also offers wide whitewall choices and 205/70R14 opens the door to redline, dual redline, raised white letter, and blackwall styles.
The right visual match depends on how the car is being finished rather than on one universally correct answer. A more formal Century can lean toward whitewall styling, while a sportier build may suit redline or raised white letters. When exact originality matters, compare the tire choice against marque references and the car's own historical details.
Does correct tire fitment matter for a 1979 Buick Century restoration?
Correct tire fitment matters on a 1979 Buick Century restoration because the size affects both stance and visual proportion, and this model family does not rely on one tire size across every sub-model. Using the proper 14-inch radial size for the exact Coupe, V6, or Wagon application keeps the tire choice grounded in the vehicle's actual configuration.
Appearance details come after size is settled. A wide whitewall, narrow whitewall, or sport-oriented sidewall treatment can all change how the Buick reads visually, but the restoration will look more convincing when the basic fitment is right first. Verifying the wheel setup before installation helps avoid a finished look that seems obviously out of place.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1979 Buick Century?
Yes, modifications can affect tire fitment on a 1979 Buick Century even when the nominal size looks close to stock. Aftermarket wheels, changes in wheel width, altered ride height, suspension repairs, or bodywork can all influence how a 205/70R14, 185/75R14, or 195/75R14 tire sits within the fender and steering range.
That is why the existing wheel and tire setup should be inspected before replacing anything on a modified car. Clearance at full steering lock, suspension travel, and sidewall-to-body space are all worth checking. A Century that has stayed original is simpler, but any change in wheels or stance can alter what works comfortably.
What should I inspect before driving a 1979 Buick Century on new tires?
Before driving a 1979 Buick Century on new tires, inspect the wheels for damage, confirm the correct tire size for the sub-model, and make sure all four tires are seated and inflated properly. It also helps to check for rubbing at the fenders or steering components, especially if the car has been sitting or has changed wheels at some point.
Road readiness goes beyond the new tires themselves. A collector-era Buick should also have its suspension, alignment condition, and basic brake function reviewed before regular use. Taking a short initial drive and rechecking pressure afterward can reveal issues early, before the car is put into longer or higher-speed service.
How should 1979 Buick Century tires be maintained?
1979 Buick Century tires should be maintained with regular pressure checks, visual inspections, and attention to age-related condition as much as tread wear. Radial tires that spend long periods parked can still develop problems, so sidewall cracking, bulges, cuts, uneven wear, and persistent air loss all deserve attention before the car returns to regular use.
Storage habits matter on a lower-use vintage Buick. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, and moving the vehicle occasionally can reduce flat-spotting concerns. Routine inspection is especially important when the Century is driven seasonally rather than every week.
