The 1986 Pontiac Bonneville came from the last era of big, comfortable American front-engine sedans that still balanced traditional full-size presence with increasingly modern road manners. Buyers looking at one today are often preserving a clean original cruiser, reviving a family survivor, or sorting out a period-correct street car with the right stance. Tire fitment centers on two 14-inch radial sizes, 195/75R14 and 205/70R14, depending on the exact Bonneville configuration. That gives room to choose among whitewall, blackwall, redline, dual-redline, and raised white letter presentations. The key is matching the right size first, then choosing the look and driving character that best suits the car.
Which Tire Size Is Right for The 1986 Pontiac Bonneville
The 1986 Pontiac Bonneville uses two primary tire sizes, both in radial construction on 14-inch rims. The first step is confirming the exact sub-model, because some versions use only 205/70R14 while others can use either 195/75R14 or 205/70R14. Once the correct size is confirmed, the decision shifts to sidewall style, tire series, brand, and the overall look you want on the car.
Fit(s): (1/2 inch studs), Base, LE, and LE (1/2 inch studs)
Construction: Radial|Rim: 14 in
195/75R14 is a metric radial size in which 195 represents nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 14 is the wheel diameter in inches. On the 1986 Pontiac Bonneville, this size supports a more traditional full-sidewall look within the car's 14-inch fitment family. Available choices include wide whitewall and narrow whitewall styles from Coker Classic, Tornel, Maxxis, and Travelstar across several tire series. This size is worth considering when your Bonneville calls for it and you want a distinctly period-style presentation.

205/70R14 is also a metric radial size, with a 205-millimeter nominal section width, a 70-series profile, and a 14-inch rim diameter. For the 1986 Pontiac Bonneville, it is the more widely shared fitment across Brougham and Handling Package applications and also appears on several other sub-models. Product choices span narrow whitewall, blackwall, redline, dual-redline, and raised white letter treatments from Maxxis, BFGoodrich, and Michelin. It is the size to evaluate when your sub-model points to a slightly sportier visual character within the same 14-inch wheel diameter.
Sub-model fitment matters on the 1986 Pontiac Bonneville because some versions can use either primary size while others are tied specifically to 205/70R14. Confirming the exact sub-model is the quickest way to narrow the tire decision before comparing sidewall styles or product families.

1986 Pontiac Bonneville (1/2 inch studs)
This Bonneville configuration uses radial tires on 14-inch rims and can be matched with either of the two primary sizes used within the model range. That makes wheel verification and current vehicle setup especially important before choosing between a more traditional whitewall presentation and a lower-profile alternative.
The Bonneville Base can use either 195/75R14 or 205/70R14, both in radial construction on 14-inch wheels. Selection usually comes down to confirming the wheel setup already on the car and then choosing the appearance you want, from classic whitewalls to more sport-oriented sidewall treatments.
The Bonneville Brougham uses 205/70R14 radial tires. That keeps the fitment question straightforward and lets the focus move to product character, including whitewall, blackwall, redline, dual-redline, or raised white letter styling depending on how original or personalized the car is meant to look.
This Brougham configuration also uses 205/70R14 radial tires on 14-inch rims. With the size narrowed down, the main choice becomes visual presentation and tire series, along with confirming wheel width and clearance if the car has been altered from its original wheel setup.
The Bonneville LE can use either 195/75R14 or 205/70R14 in radial construction. That means the correct tire depends on the exact wheel and vehicle configuration, after which the selection can be tailored toward a softer whitewall look or a more assertive redline or lettered style.
This LE variation shares the broader fitment pattern and can use either primary 14-inch radial size. Checking the wheels currently on the car is the practical first move, especially if the goal is to balance authentic late-1980s appearance with the sidewall style that best suits the restoration.
The Handling Package version uses 205/70R14 radial tires. That points the tire decision away from size hunting and toward choosing the right series and sidewall treatment, particularly for owners who want the car's sharper package identity to carry through in the tire appearance.
1986 Pontiac Bonneville w/Handling Pkg. (1/2 inch studs)
This Handling Package configuration also uses 205/70R14 radial tires. Tire selection is therefore centered on style and specification details within that size, while still checking actual wheel width and clearance if the car has aftermarket wheels or suspension changes.
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.

Common questions for the 1986 Pontiac Bonneville usually center on which of the two 14-inch radial sizes applies, how sub-model fitment differs, and how to choose among whitewall, redline, blackwall, and raised white letter options.
Tire Size & Fitment
What tire size fits a 1986 Pontiac Bonneville?
A 1986 Pontiac Bonneville uses one of two primary radial tire sizes: 195/75R14 or 205/70R14. Both sizes fit 14-inch wheels, but they do not apply the same way across every Bonneville configuration. Brougham and Handling Package versions use 205/70R14, while several other Bonneville sub-models can use either size.
The practical step is to confirm the exact sub-model and the wheels currently on the car before choosing a tire. Many Bonnevilles have changed hands, and some may have different wheels than they started with. Once the size is confirmed, the remaining choice is mostly about sidewall style, tire series, and the overall appearance you want.
What size rim does a 1986 Pontiac Bonneville use?
The 1986 Pontiac Bonneville uses 14-inch rims with both of its primary tire sizes, 195/75R14 and 205/70R14. The final number in each size is the wheel diameter, so both tires are built for a 14-inch wheel. That keeps rim diameter simple even though the model range includes two different tire sizes.
Rim diameter is only part of the fitment picture, so it still helps to check wheel width before selecting a specific tire. Some available products have different approved rim-width ranges within the same 14-inch diameter. That matters most if the car has replacement wheels, because correct diameter alone does not settle the full fitment decision.
Do all 1986 Pontiac Bonneville sub-models use the same tire size?
No. The 1986 Pontiac Bonneville range does not use one universal tire size across every sub-model. Brougham and Handling Package versions use 205/70R14, while the Base, LE, and certain Bonneville configurations can use either 195/75R14 or 205/70R14, all in radial construction on 14-inch rims.
That difference matters because a buyer should not assume that every Bonneville takes the same tire simply because the wheel diameter matches. The best approach is to identify the exact sub-model first, then compare the wheels actually installed on the car. That keeps the choice focused and avoids selecting a tire only by appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 1986 Pontiac Bonneville?
Start with the correct size for the specific Bonneville configuration, since the 1986 model range uses either 195/75R14 or 205/70R14. Both are radial tires for 14-inch rims, but not every sub-model uses both sizes. After size, the biggest differences come from sidewall style, tire series, rim-width compatibility, and the visual character each tire gives the car.
A restoration-minded sedan may look best with a whitewall, while a sportier presentation may lean toward redline or raised white letter styling. It also helps to compare product details such as approved wheel width and load figures where they are shown. Matching the tire to the car's intended use and appearance usually leads to the clearest decision.
What sidewall styles are available for 1986 Pontiac Bonneville tires?
Tires for the 1986 Pontiac Bonneville are available in several sidewall styles, including wide whitewall, narrow whitewall, blackwall, redline, dual-redline, and raised white letter. The exact style depends on which primary size you need. The broader selection appears in 205/70R14, while 195/75R14 is oriented more toward whitewall choices.
That variety lets the car lean either more formal or more performance-inspired without changing the basic tire category. Whitewalls usually suit a traditional Bonneville presentation, while redlines, dual-redlines, or raised white letters give a stronger visual accent. The right choice depends on the sub-model, the period look you prefer, and whether the car is restored or personalized.
What brands offer tires for the 1986 Pontiac Bonneville?
The 1986 Pontiac Bonneville has tire options from Coker Classic, Tornel, Maxxis, Travelstar, BFGoodrich, and Michelin. Brand availability depends on the tire size. The 195/75R14 fitment includes Coker Classic, Tornel, Maxxis, and Travelstar, while 205/70R14 includes Maxxis, BFGoodrich, and Michelin across several different sidewall presentations.
Brand choice is most useful when it helps narrow the look and specification you want rather than treating one name as automatically better. Some buyers are searching for a clean whitewall radial, while others want redlines, blackwalls, or raised white letters. Once the correct size is confirmed, brand becomes part of the visual and product-series decision.
Restoration & Appearance
Which tire should I choose for a period-style 1986 Pontiac Bonneville?
A period-style 1986 Pontiac Bonneville should begin with the correct primary size for the sub-model, either 195/75R14 or 205/70R14, both in radial construction on 14-inch wheels. From there, the appearance choice becomes the key decision. Whitewall radials usually create the most traditional Bonneville presentation, while redline or raised white letter options add a more customized late-1980s flavor.
The best visual match depends on how the car is being preserved. A formal Brougham or a clean original-style sedan often looks most natural with a whitewall treatment, while a more individualized car may suit a stronger sidewall accent. When exact originality matters, compare the tire choice against marque references and the car's own historical details.
How does tire construction affect the appearance of a restored 1986 Pontiac Bonneville?
On a restored 1986 Pontiac Bonneville, tire construction is straightforward because the primary fitments are radial tires. That means the appearance difference is less about bias-ply versus radial and more about the proportions and sidewall treatment within the correct size. A 195/75R14 and a 205/70R14 can give the car a noticeably different visual attitude even though both use 14-inch wheels.
The sidewall style then does much of the visual work. Wide or narrow whitewalls tend to reinforce the Bonneville's upscale, traditional character, while blackwalls, redlines, dual-redlines, and raised white letters move the look in a sportier direction. Matching the right size first keeps the restored car from looking unintentionally over-tired or under-tired on its wheels.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1986 Pontiac Bonneville?
Yes. Modifications can affect tire fitment on a 1986 Pontiac Bonneville even when the tire still has the correct 14-inch rim diameter. Aftermarket wheels, different wheel widths, altered offsets, lowering, spring changes, or body work can all change how a 195/75R14 or 205/70R14 sits in the wheel opening and how it clears during steering and suspension movement.
That is especially important on a Bonneville that could use more than one primary size depending on configuration. A tire that matches the model family may still need a closer check on a modified car. Measuring the actual wheels and checking fender and steering clearance before installation is the safest way to avoid fitment surprises.
What should I inspect before driving a 1986 Pontiac Bonneville on new tires?
Before driving a 1986 Pontiac Bonneville on new tires, inspect the wheels for the correct 14-inch diameter, verify that the wheel width suits the tire being installed, and make sure the tires are inflated properly. It also helps to look over the suspension, steering components, and alignment condition so the new tires start life on a sound chassis.
A short clearance check is worthwhile before regular road use. Turn the steering lock to lock, look for any contact points, and confirm that the tires sit cleanly within the fenders. After the first few drives, recheck pressure and look for unusual wear or rubbing marks, especially if the car has replacement wheels or older suspension parts.
How should tires on a collector 1986 Pontiac Bonneville be maintained?
Collector-car tires on a 1986 Pontiac Bonneville benefit from regular pressure checks, routine visual inspection, and clean storage conditions. Even a low-mile car should be watched for sidewall cracking, cuts, bulges, uneven tread wear, or slow air loss. Those basics matter whether the Bonneville runs 195/75R14 or 205/70R14 radials.
Storage habits make a real difference on a car that spends long periods parked. Keeping the Bonneville away from prolonged heat, direct sunlight, standing moisture, and ozone sources helps preserve the tires over time. Occasional movement also helps avoid long static loading in one spot, and any sign of age-related deterioration deserves closer inspection before road use.
