The 1993 Pontiac Bonneville came from an era when full-size Pontiac sedans balanced comfort, V6-powered highway manners, and a more assertive design language than many of their domestic rivals. By the early 1990s, Bonneville buyers were also seeing more variation in wheel and tire packages within the same model line. For this exact 1993 Pontiac Bonneville, the key fitment question centers on two radial sizes: 215/65R15 and 225/60R16. That opens the door to choices in sidewall appearance, tire series, and brand depending on the wheel setup already on the car. Before selecting a tire, confirm the sub-model and wheel diameter so the replacement matches the car's actual configuration and intended look.
Which Tire Size Is Right for The 1993 Pontiac Bonneville
The 1993 Pontiac Bonneville uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. Both fitments are radial, but they do not share the same rim size, so the first step is confirming whether the car is on 15-inch or 16-inch wheels. Once that is settled, the real choice becomes sidewall style, tire series, brand, and how closely the tire's appearance matches the way the car is being preserved or driven.
215/65R15 is a metric radial size in which 215 identifies nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 15 is the wheel diameter in inches. On the 1993 Pontiac Bonneville, this size is used on 15-inch wheel applications and keeps the selection firmly in modern radial construction. Available choices include Goodyear, Cooper, and BFGoodrich, with sidewall treatments such as OWL, RWL, redline, and wide whitewall across several series. This size is the right starting point when the car has the proper 15-inch wheel setup and the goal is to balance fitment with a specific visual style.
225/60R16 is also a metric radial size, with 225 representing nominal section width in millimeters, 60 describing the aspect ratio, and 16 identifying the wheel diameter in inches. For the 1993 Pontiac Bonneville, this size belongs to 16-inch wheel applications and is the standard fitment for the SSE and SSEi. Product choices span Goodyear, BFGoodrich, and Travelstar, with raised yellow letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall presentations. This is the size to evaluate when the car carries the larger wheel package and the tire needs to suit both the wheel dimensions and the car's intended appearance.
Sub-model fitment matters on the 1993 Bonneville because tire size is not the same across every version. The SE can use either of the two radial sizes, while the SSE and SSEi are tied to the 16-inch fitment, so identifying the exact trim and wheel setup is the first step before comparing tires.

1993 Pontiac Bonneville SE
The 1993 Pontiac Bonneville SE is the most variable trim here because it can use either the 215/65R15 or 225/60R16 radial fitment. Tire selection starts with confirming which wheel diameter is actually on the car, then narrowing choices by sidewall style, brand, and overall presentation.
The 1993 Pontiac Bonneville SSE uses the 225/60R16 radial fitment on a 16-inch wheel. That makes the size decision straightforward, so the focus shifts to choosing among available sidewall looks such as raised yellow letter, redline, or whitewall-style options.
The 1993 Pontiac Bonneville SSEi also uses the 225/60R16 radial fitment. With the size established, the main considerations become wheel compatibility, preferred sidewall treatment, and whether the tire's visual character suits a stock-appearing car or a more personalized presentation.
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 1993 Pontiac Bonneville?
A 1993 Pontiac Bonneville uses either 215/65R15 or 225/60R16, and both are radial tire sizes. The correct fitment depends on the sub-model and the wheel package on the car, with the SE using either size and the SSE and SSEi using 225/60R16.
The safest starting point is the wheel already on the car. A 15-inch wheel calls for the 215/65R15 fitment, while a 16-inch wheel calls for 225/60R16. If the Bonneville has changed hands, aftermarket wheels, or replacement rims from another trim, confirm the actual wheel diameter before choosing a tire.
What size rim does a 1993 Pontiac Bonneville use?
The 1993 Pontiac Bonneville uses either a 15-inch or 16-inch rim, depending on the tire size and sub-model configuration. The 215/65R15 fitment uses a 15-inch rim, while the 225/60R16 fitment uses a 16-inch rim.
That difference matters because tire size cannot be separated from wheel diameter. A 15-inch tire does not belong on a 16-inch wheel, and vice versa. On an SE, either diameter may be present, so checking the wheel itself is more useful than assuming by trim name alone.
Do all 1993 Pontiac Bonneville sub-models use the same tire size?
No, the 1993 Pontiac Bonneville sub-models do not all use the same tire size. The SE can use 215/65R15 or 225/60R16, while the SSE and SSEi use 225/60R16 only.
That means the exact trim helps narrow the fitment, but the wheel on the car still deserves a close look. An SE has the widest fitment range of the group, so owners should confirm wheel diameter and compare the current setup before ordering a replacement based only on the Bonneville model name.
Choosing the Right Tire
What should I consider when choosing a 1993 Pontiac Bonneville tire?
Start with the correct primary size for the car: 215/65R15 on a 15-inch wheel or 225/60R16 on a 16-inch wheel. From there, compare radial construction details, rim-width specifications, sidewall styling, and the tire series that best matches how the Bonneville is used and presented.
Some owners want a straightforward 1990s performance look, while others prefer a more traditional whitewall or redline presentation. It also helps to compare load figures, pressure references, and wheel-width compatibility so the chosen tire suits the car's actual wheels rather than just matching the size molded on the sidewall.
What sidewall styles are available for 1993 Pontiac Bonneville tires?
Sidewall choices for the 1993 Pontiac Bonneville vary by tire size and product line. Available styles include OWL, RWL, redline, raised yellow letter, pin-white-stripe, wide whitewall, and narrow whitewall, depending on whether the car uses 215/65R15 or 225/60R16.
That variety makes appearance a real part of the buying decision, especially on a sedan that may be preserved in stock style or personalized to suit the owner's taste. Matching the sidewall treatment to the wheel design and overall look of the car usually produces a better result than selecting by brand name alone.
What brands offer tires for the 1993 Pontiac Bonneville?
Tires for the 1993 Pontiac Bonneville are available from Goodyear, Cooper, BFGoodrich, and Travelstar across the two primary radial sizes. Brand availability depends on size, with some names appearing only in 215/65R15 and others appearing only in 225/60R16.
The more useful comparison is how each brand's available series and sidewall options fit the car's needs. One Bonneville owner may want raised-letter styling, while another may prefer a cleaner whitewall or redline presentation. Comparing the actual size-specific options usually matters more than choosing a brand first.
Restoration & Appearance
Which tire should I choose for a period-style 1993 Pontiac Bonneville?
A period-style 1993 Pontiac Bonneville tire starts with the correct size for the car's wheel setup, either 215/65R15 or 225/60R16, since both are authentic to the model year fitment range. From there, sidewall treatment becomes the main visual choice, with options that include RWL, OWL, redline, and several whitewall presentations.
The right look depends on how the Bonneville is being preserved. A sportier trim may suit raised-letter styling, while a more traditional presentation can lean toward pin-white-stripe or whitewall options. If exact historical presentation matters, compare the tire choice with original photos, window-sticker materials, or marque-specific references.
How does tire construction affect the appearance of a restored 1993 Pontiac Bonneville?
Tire construction is straightforward on the 1993 Pontiac Bonneville because both primary fitments are radial. The visual difference comes less from construction type and more from the sidewall style, tire series, and the proportion created by the correct 15-inch or 16-inch wheel package.
A restored Bonneville can look noticeably different with raised letters, redlines, or whitewalls even when the size remains correct. Keeping the proper tire size for the wheel package usually preserves the car's stance more effectively than chasing a particular style first, especially when the goal is a clean and era-appropriate appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1993 Pontiac Bonneville?
Yes, modifications can affect tire fitment on a 1993 Pontiac Bonneville even when the tire size itself is correct. Aftermarket wheels, changes in wheel width, altered offset, lowering, replacement springs, or body and suspension work can all change the amount of clearance around the tire.
That matters most on an SE, where either 15-inch or 16-inch setups may appear, but it applies to every trim. A Bonneville with non-original wheels should be checked for wheel diameter, rim width, steering clearance, and fender room before new tires are installed, especially if the suspension no longer sits at stock height.
What should I inspect before driving a 1993 Pontiac Bonneville on new tires?
Before driving a 1993 Pontiac Bonneville on new tires, inspect the wheels for damage, confirm the correct wheel diameter, and make sure the tires are seated and inflated properly. It is also smart to check for suspension wear, uneven old tire wear patterns, and any signs that alignment or steering parts need attention.
A short test drive should include listening for rubbing on turns and watching for vibration or pull. Older Bonnevilles may have sat for periods of time, so it helps to inspect brake components and verify that the car tracks straight once the new tires are mounted and the pressures are set correctly.
How often should tires on a 1993 Pontiac Bonneville be inspected?
Tires on a 1993 Pontiac Bonneville should be inspected regularly, especially if the car is driven infrequently. Pressure checks, tread inspection, and a close look for cracking, bulges, cuts, or slow air loss are worthwhile before routine use and particularly before longer highway trips.
Collector-era and lightly used cars often age their tires before they wear them out, so condition matters as much as tread depth. A Bonneville that spends time parked should also be kept away from prolonged heat, direct sunlight, and ozone sources, with periodic checks to catch aging issues before they become road-use problems.
