The 1997 Mitsubishi Diamante came from an era when imported full-size sedans were expected to balance comfort, clean styling, and confident highway manners. It sits in the late-1990s near-luxury segment, so tire choice matters not just for appearance, but for how the car feels on the road. This model uses radial tire fitments in either 205/65R15 or 215/60R16, depending on sub-model and wheel setup. In 205/65R15, available choices include BFGoodrich Silvertown Radial options with either a wide whitewall or redline sidewall treatment. The key step is confirming the exact sub-model and wheel diameter before choosing a tire that suits restoration-minded styling or regular road use.
Which Tire Size Is Right for The 1997 Mitsubishi Diamante
The 1997 Mitsubishi Diamante uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Both are radial metric sizes, but one fits a 15-inch rim and the other fits a 16-inch rim. Before choosing a tire, confirm whether the car is equipped for 205/65R15 or 215/60R16, since wheel diameter is the first fitment checkpoint.
205/65R15 is a metric radial size where 205 identifies nominal section width in millimeters, 65 is the aspect ratio, R denotes radial construction, and 15 is the rim diameter in inches. On the 1997 Mitsubishi Diamante, this size belongs to a 15-inch wheel setup rather than the 16-inch alternative used elsewhere in the range. Available choices in this size include BFGoodrich Silvertown Radial tires with either a 2-inch whitewall or a redline sidewall. This size is the one to evaluate when maintaining the 15-inch wheel package and choosing between traditional sidewall appearances.
215/60R16 is a metric radial size with a 215-millimeter nominal section width, a 60-series profile, radial construction, and a 16-inch rim diameter. For the 1997 Mitsubishi Diamante, this size serves the 16-inch wheel fitment and should not be confused with the 15-inch 205/65R15 setup. Its role in the fitment lineup is to match cars equipped for the larger wheel diameter, including LS applications and some ES configurations. Choosing this size starts with confirming the actual wheel on the car, especially if wheels may have been changed over time.
Sub-model fitment matters on the 1997 Mitsubishi Diamante because tire size is not the same across the full lineup. The ES can use either of the two primary sizes, while the LS uses the 16-inch radial fitment, so the exact version and wheel package should be confirmed first.

1997 Mitsubishi Diamante ES
The 1997 Mitsubishi Diamante ES can use either a 205/65R15 radial or a 215/60R16 radial, so wheel diameter is the critical detail on this sub-model. Tire selection starts with confirming whether the car is on its 15-inch or 16-inch setup before comparing style and construction details.
The 1997 Mitsubishi Diamante LS uses the 215/60R16 radial fitment tied to a 16-inch wheel. That makes the tire decision more straightforward, with the main priority being confirmation of the existing wheel setup if the car has seen wheel 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.

Tire Size & Fitment
What tire size fits a 1997 Mitsubishi Diamante?
A 1997 Mitsubishi Diamante uses either 205/65R15 or 215/60R16, depending on sub-model and wheel setup. Both are radial metric tire sizes, but they are tied to different rim diameters, so they are not the same fitment choice.
The ES can use either size, while the LS uses 215/60R16. That makes wheel confirmation especially important on an ES, since the correct tire depends on whether the car is equipped with a 15-inch or 16-inch rim. If the car has had wheel changes over the years, checking the actual wheel before selecting a tire is the safest next step.
What size rim does a 1997 Mitsubishi Diamante use?
The 1997 Mitsubishi Diamante uses either a 15-inch or 16-inch rim, depending on tire size and sub-model configuration. The 205/65R15 tire fits a 15-inch rim, while the 215/60R16 tire fits a 16-inch rim.
Rim diameter should be confirmed before anything else because a 15-inch tire cannot be mounted on a 16-inch wheel, and the reverse is also true. On an ES model, either wheel diameter may be present, so visual assumptions can lead to the wrong choice. Reading the current tire size or measuring the wheel diameter will narrow the fitment quickly.
Why does the 1997 Mitsubishi Diamante have more than one tire size?
The 1997 Mitsubishi Diamante has more than one tire size because fitment varies by sub-model and wheel package. The range includes both 205/65R15 and 215/60R16 radial sizes, and those sizes correspond to different wheel diameters on the car.
That difference does not mean both sizes automatically apply to every Diamante. The LS uses the 16-inch setup, while the ES may use either size. For an owner replacing tires, the practical issue is identifying the exact sub-model and confirming the wheel currently on the vehicle, especially if it has passed through multiple owners or received aftermarket wheel changes.
Choosing the Right Tire
What should I consider when choosing a 205/65R15 tire for a 1997 Mitsubishi Diamante?
Start with the basics: the car must actually use the 205/65R15 fitment and have the 15-inch wheel that belongs with it. In this size, the available choices are BFGoodrich Silvertown Radial tires, with the same radial construction and the same series offered in different sidewall treatments.
That means the main decision is visual character rather than changing tire type. A wide whitewall gives the Diamante a more formal, restoration-oriented presentation, while a redline adds a sportier period-style touch. It also helps to compare the tire's rim-width specification to the wheel on the car so the chosen tire suits the actual wheel, not just the nominal size.
What sidewall styles are available for 1997 Mitsubishi Diamante tires?
For the 1997 Mitsubishi Diamante in 205/65R15, the available sidewall styles are a 2-inch wide whitewall and a redline. Both are offered on BFGoodrich Silvertown Radial tires, so the underlying construction and tire series remain consistent while the visual treatment changes.
That makes sidewall choice largely an appearance decision. A wide whitewall leans toward a more formal vintage-inspired look, while a redline gives the car a sharper period-style accent. Since sidewall treatment can change the overall presentation of the car more than many owners expect, it is worth considering the Diamante's color, trim, and restoration goals before settling on one style.
What brands offer tires for the 1997 Mitsubishi Diamante?
BFGoodrich is the brand represented in the available 205/65R15 tire selection for the 1997 Mitsubishi Diamante. Those choices fall under the Silvertown Radial series and differ by sidewall style rather than by a change in construction type or basic size.
Because the available products in this fitment stay within one brand and one series, the comparison is more focused than on some older collector applications. The decision comes down to confirming the correct wheel diameter first, then choosing the sidewall treatment that best matches the car's intended look. Rim-width compatibility is also worth checking against the wheel currently mounted on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1997 Mitsubishi Diamante?
A period-style choice for a 1997 Mitsubishi Diamante starts with the correct primary size for the car's wheel setup, then moves to sidewall appearance. In 205/65R15, BFGoodrich Silvertown Radial options are available with either a 2-inch whitewall or a redline, giving two very different visual directions.
The better match depends on how the car is being presented. A wide whitewall gives the Diamante a more formal, upscale look, while a redline tends to feel more assertive and late-1990s custom in character. Owners pursuing exact originality should compare any appearance choice against marque-specific references, since a period-style look is not the same thing as a documented factory-delivered tire treatment.
How does tire construction affect the appearance of a restored 1997 Mitsubishi Diamante?
On the 1997 Mitsubishi Diamante, construction is straightforward because the primary fitments are radial sizes rather than vintage bias-ply applications. The visual character of the tire therefore comes less from a bias-versus-radial decision and more from the tire's profile and sidewall treatment within the correct size.
That is why appearance choices such as wide whitewall or redline can matter so much on a restoration-minded sedan from this era. Even when the size is correct, the sidewall can push the car toward a formal luxury look or a more customized period presentation. Matching the tire's look to the car's trim, stance, and intended use usually matters more here than construction nostalgia.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1997 Mitsubishi Diamante?
Yes. Modifications can change tire fitment on a 1997 Mitsubishi Diamante even when the original size range is known. Aftermarket wheels, altered wheel width, suspension changes, or a lowered stance can all affect how a 205/65R15 or 215/60R16 tire sits and clears the body.
That is especially important on an ES, where either a 15-inch or 16-inch setup may already be in play. A car that no longer carries its original wheel package should be checked for actual rim diameter, wheel width, and clearance at steering and suspension travel before a replacement tire is chosen. Modified cars need verification on the vehicle, not just by year and model.
What should I inspect before driving a 1997 Mitsubishi Diamante on new tires?
Before driving a 1997 Mitsubishi Diamante on new tires, inspect the wheels for damage, verify the tire size matches the wheel diameter, and make sure inflation is set correctly for the installed tires. It also helps to look over the suspension and alignment condition so the new tires start life on a sound chassis.
A low-use sedan can hide problems that fresh tires alone will not solve. Check for uneven wear patterns from previous alignment issues, rubbing at full steering lock, and signs of looseness in steering or suspension components. After the first few drives, recheck air pressure and look for any interference marks, especially if the car has replacement wheels or a changed ride height.
How should tires on a collector 1997 Mitsubishi Diamante be maintained?
Tires on a collector or infrequently driven 1997 Mitsubishi Diamante should be checked regularly for air loss, sidewall cracking, tread condition, cuts, and bulges. Even when mileage stays low, age and storage conditions can affect tire condition long before tread wear becomes the reason for replacement.
Storage habits matter on a late-1990s collector sedan. Keeping the car away from prolonged sunlight, excess heat, standing moisture, and ozone-producing equipment can help preserve the tires between drives. It is also smart to inspect the spare, confirm the wheel setup still matches the tire size on the car, and give the tires a close look before any longer highway trip.
