The 1987 Pontiac Bonneville comes from a period when full-size American comfort cars were blending traditional road manners with more modern wheel and tire sizing. Buyers looking at this exact Bonneville are usually balancing clean original-style fitment with the right stance and sidewall presentation for a well-kept late-classic GM sedan. Tire fitment depends on sub-model, with the Base using 205/70R14 radials and the LE using 215/65R15 radials. That opens the door to choices in blackwall, whitewall, redline, raised white letter, and touring or sportier radial series. The key is confirming whether the car is a Base or LE and matching the wheel diameter before comparing appearance and construction details.
Which Tire Size Is Right for The 1987 Pontiac Bonneville
The 1987 Pontiac Bonneville uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. Both are radial fitments, but one uses a 14-inch rim and the other uses a 15-inch rim, so confirming whether the car is a Base or LE should come before comparing sidewall style, tire series, or brand options.
205/70R14 is a metric radial size in which 205 identifies the section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the wheel diameter in inches. On the 1987 Pontiac Bonneville, this size is used on the Base model and keeps the fitment in a distinctly late-1980s passenger-car format. Available choices include narrow whitewall, redline, dual-redline, raised white letter, and blackwall designs from Maxxis, BFGoodrich, and Michelin across several series. This size makes the most sense when the car still carries its 14-inch wheel setup and the goal is to match either a conservative touring look or a more customized period-style appearance.
215/65R15 is a metric radial size where 215 is the section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 indicates a 15-inch rim. This size belongs to the 1987 Pontiac Bonneville LE and moves the car to a different wheel diameter, so it should not be selected until the wheel setup is confirmed. Product choices include wide whitewall, redline, raised white letter, and outlined white letter styles from Goodyear, Cooper, and BFGoodrich in several radial series. It is the size to evaluate when the Bonneville has the LE wheel package and the buyer wants to balance correct diameter with the right visual character.
Sub-model identification matters on the 1987 Pontiac Bonneville because tire fitment changes between the Base and LE. The two versions use different wheel diameters, so choosing tires starts with confirming the exact trim and the wheels currently on the car.

1987 Pontiac Bonneville Base
The 1987 Pontiac Bonneville Base uses a 205/70R14 radial setup on a 14-inch wheel. Tire selection here centers on maintaining the correct diameter class while choosing among touring-style blackwall and whitewall options or more distinct redline and raised white letter presentations.
The 1987 Pontiac Bonneville LE uses a 215/65R15 radial tire on a 15-inch wheel. That makes wheel confirmation essential before shopping, then the decision shifts to whether the car should wear a traditional whitewall treatment or a more performance-flavored 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 1987 Pontiac Bonneville?
A 1987 Pontiac Bonneville uses one of two radial tire sizes depending on sub-model. The Base model uses 205/70R14, while the LE uses 215/65R15. Both are modern metric radial sizes, but they are tied to different wheel diameters, so they are not simply alternate versions of the same fitment.
The practical first step is identifying whether the car is a Base or LE and then confirming the wheel diameter currently on the vehicle. Many older cars have seen wheel changes over time, so the correct tire decision should match both the sub-model and the actual 14-inch or 15-inch wheel setup before comparing brands or sidewall styles.
What size rim does a 1987 Pontiac Bonneville use?
The 1987 Pontiac Bonneville uses either a 14-inch or 15-inch rim, depending on sub-model. A Bonneville Base is paired with a 14-inch wheel and 205/70R14 tires, while a Bonneville LE uses a 15-inch wheel with 215/65R15 tires. That rim difference is one of the most important fitment distinctions on this car.
Wheel diameter should be confirmed before shopping because a tire designed for a 14-inch rim cannot be mounted on a 15-inch wheel, and the reverse is also true. It is also worth checking wheel width when comparing products, especially if the car has aftermarket wheels or replacement factory-style wheels installed during its life.
Why does the 1987 Pontiac Bonneville have more than one tire size?
The 1987 Pontiac Bonneville has more than one tire size because fitment changes by sub-model. The Base uses 205/70R14, while the LE uses 215/65R15. Both are radial tires, but the Bonneville line was not built around one universal wheel and tire package for every trim.
That means tire selection starts with the exact version of the car rather than the Bonneville name alone. An owner should also verify that the current wheels still match the original diameter class for that trim, since a previous owner may have changed wheels, tires, or suspension height in ways that affect what should be purchased now.
Choosing the Right Tire
What should I consider when choosing a 1987 Pontiac Bonneville tire?
Start with the correct size for the car’s sub-model and wheel diameter: 205/70R14 for the Base or 215/65R15 for the LE. From there, compare radial tire construction details such as sidewall style, tire series, and wheel-width compatibility. Those factors shape both the appearance of the Bonneville and how closely the tire matches the wheel setup on the car.
A Bonneville kept in a more original-looking presentation may lean toward whitewall or blackwall styling, while a more customized or performance-flavored look may point toward redline, outlined white letter, or raised white letter options. Load capacity and rim-width range are also worth reviewing so the tire choice suits the wheel and expected road use.
What sidewall styles are available for 1987 Pontiac Bonneville tires?
Sidewall choices for the 1987 Pontiac Bonneville include blackwall, narrow whitewall, wide whitewall, redline, dual-redline, RWL, and OWL depending on tire size. The 205/70R14 selection includes blackwall, narrow whitewall, redline, dual-redline, and RWL styles, while 215/65R15 adds wide whitewall and OWL choices along with redline and RWL options.
That variety makes sidewall style one of the biggest visual decisions on this page. A whitewall can support a more formal late-1980s full-size look, while redline and lettered sidewalls create a stronger performance or custom impression. The right choice depends on the car’s trim, wheel design, and whether the goal is restoration-minded presentation or a more personalized appearance.
What brands offer tires for the 1987 Pontiac Bonneville?
Tires for the 1987 Pontiac Bonneville are available from BFGoodrich, Michelin, Maxxis, Goodyear, and Cooper, depending on size. The 205/70R14 fitment includes BFGoodrich, Michelin, and Maxxis choices, while the 215/65R15 fitment includes BFGoodrich, Goodyear, and Cooper. Each brand appears in radial construction for this Bonneville application.
Brand alone is only part of the decision. It helps to compare which series and sidewall treatments are actually offered in the needed size, since one brand may provide a traditional whitewall look while another may emphasize raised white letter or sportier styling. Matching the tire to the wheel size and intended visual character usually matters more than the badge on the sidewall.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Pontiac Bonneville?
A period-style 1987 Pontiac Bonneville tire choice starts with the correct sub-model size: 205/70R14 for the Base or 215/65R15 for the LE. From there, the most restoration-oriented direction usually comes from selecting a radial with a traditional sidewall treatment such as blackwall, narrow whitewall, or wide whitewall rather than choosing strictly by brand name.
The right visual result depends on how the car is being presented. A formal sedan look may favor whitewall styling, while a cleaner late-1980s appearance may lean blackwall. When exact originality matters, compare the tire choice against period photos, sales literature, and marque-specific references so the finished look matches the character of the individual Bonneville.
How does tire construction affect the appearance of a restored 1987 Pontiac Bonneville?
Tire construction is straightforward on the 1987 Pontiac Bonneville because both primary fitments are radial. That means the appearance difference comes less from bias-ply versus radial construction and more from the sidewall treatment, tire series, and overall profile of the selected 205/70R14 or 215/65R15 tire.
On a restored or carefully preserved Bonneville, those appearance details have a noticeable effect. A wide or narrow whitewall can make the car feel more formal, while redline or lettered sidewalls push it toward a sportier or more customized presentation. Choosing the correct size first keeps the proportions right, then the sidewall style sets the personality.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Pontiac Bonneville?
Yes, modifications can affect tire fitment on a 1987 Pontiac Bonneville even when the tire size matches a recognized Base or LE application. Aftermarket wheels, different wheel widths, suspension changes, or body alterations can change clearance at the fender, steering components, or suspension, especially when moving between the car’s original 14-inch and 15-inch wheel packages.
A modified Bonneville should be checked as an actual vehicle rather than treated like an untouched trim package. Wheel diameter, wheel width, and available clearance matter just as much as the printed tire size. Looking over the car at full steering lock and normal ride height helps prevent avoidable rubbing or mismatch problems after installation.
What should I inspect before driving a 1987 Pontiac Bonneville on new tires?
Before driving a 1987 Pontiac Bonneville on new tires, inspect the wheels for correct diameter and condition, confirm tire pressure, and make sure the tires clear the body and suspension. It is also smart to look at valve stems, lug hardware, and overall wheel condition so the new tires are being mounted onto sound components.
A late-classic Bonneville that sits for long periods deserves a little extra attention before road use. Check for uneven ride height, worn suspension parts, and any signs of rubbing once the car is back on the ground. A short initial drive followed by another visual inspection can catch contact issues or air-loss concerns early.
How should tires on a collector 1987 Pontiac Bonneville be maintained?
Tires on a collector 1987 Pontiac Bonneville should be kept properly inflated, inspected regularly for cracking, bulges, cuts, and irregular wear, and protected from long periods of sun and ozone exposure. Even a low-mile car benefits from routine checks because age and storage conditions can affect tire condition long before tread is worn out.
Driving the car occasionally helps, but storage habits still matter. Parking on a clean surface, keeping the car out of prolonged heat, and watching for slow air loss can preserve both the ride and the appearance of whitewall, redline, or lettered sidewalls. Any Bonneville that has been sitting should get a full tire inspection before longer road use.
