The 1998 Mitsubishi Diamante came from the final years of Mitsubishi’s upscale front-wheel-drive sedan era, when smooth highway manners and a more refined character set it apart from many mainstream family cars. Buyers looking at this exact model usually need to sort out wheel and trim differences before choosing tires, because the 1998 Mitsubishi Diamante uses either 205/65R15 or 215/60R16 radial fitment depending on configuration. Available choices here center on the 205/65R15 size, with BFGoodrich Silvertown Radial options in either a 2 Inch Whitewall or Redline sidewall treatment. The right choice depends on confirming the car’s actual wheel diameter and whether the goal is stock-style road use or a more personalized appearance.
Which Tire Size Is Right for The 1998 Mitsubishi Diamante
The 1998 Mitsubishi Diamante uses two primary tire sizes, and the first thing to confirm is wheel diameter. One fitment uses a 15-inch rim and the other uses a 16-inch rim, so the correct tire choice depends on the exact sub-model and the wheels currently on the car. Once that is settled, the decision becomes choosing the right radial tire style and overall presentation for that setup.
205/65R15 is a metric radial size that reads as 205 millimeters of section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1998 Mitsubishi Diamante, this size suits the 15-inch wheel setup and keeps the buyer focused on modern radial fitment rather than vintage sizing conventions. In this size, BFGoodrich offers Silvertown Radial choices with either a 2 Inch Whitewall or Redline sidewall treatment. It is the right size to evaluate when the car has 15-inch wheels and the owner wants to balance correct fitment with a distinct visual style.
215/60R16 is a metric radial size with a 215-millimeter section width, a 60-series profile, radial construction, and a 16-inch rim diameter. For the 1998 Mitsubishi Diamante, this size belongs to the 16-inch wheel configuration and should be treated separately from the 15-inch setup rather than as a simple substitution. The key practical difference is that wheel diameter must already match before any tire selection begins. This is the size to verify on LS models and on ES cars equipped with the larger wheel package, especially if wheels may have been changed over time.
Sub-model fitment matters on the 1998 Mitsubishi Diamante because tire size is not the same across every version. The ES can use either size, while the LS is tied to the 16-inch fitment, so identifying the exact trim and wheel setup is the first step before choosing tires.

1998 Mitsubishi Diamante ES
The 1998 Mitsubishi Diamante ES can use either the 205/65R15 radial size or the 215/60R16 radial size, depending on how the car is equipped. That makes wheel confirmation especially important before ordering, since the tire decision starts with the actual rim diameter on the vehicle rather than the model name alone.
The 1998 Mitsubishi Diamante LS uses the 215/60R16 radial fitment. For this trim, tire selection is more straightforward, but the owner should still confirm that the car remains on its intended 16-inch wheel setup if wheels have ever been changed.
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 1998 Mitsubishi Diamante?
The 1998 Mitsubishi Diamante uses two radial tire sizes: 205/65R15 and 215/60R16. The ES can use either size depending on wheel setup, while the LS uses 215/60R16. Those are two different fitments tied to two different rim diameters, not two interchangeable choices for the same wheel.
The practical step is to confirm the car’s actual wheel diameter before selecting tires. A Diamante that has had wheels changed over the years may not still match its original trim-based setup, so checking the sidewall size already on the car and measuring the wheel can prevent ordering the wrong fitment.
What size rim does a 1998 Mitsubishi Diamante use?
A 1998 Mitsubishi Diamante uses either a 15-inch or 16-inch rim, depending on sub-model and wheel configuration. The 205/65R15 tire fits a 15-inch rim, while the 215/60R16 tire fits a 16-inch rim. The ES appears in both configurations, and the LS uses the 16-inch setup.
Rim diameter is the first fitment check because a 15-inch tire cannot be mounted on a 16-inch wheel, and the reverse is also true. It is also worth checking wheel width and any aftermarket wheel changes, especially on an older sedan that may have seen replacement wheels during its service life.
Why does the 1998 Mitsubishi Diamante have more than one tire size?
The 1998 Mitsubishi Diamante has more than one tire size because fitment varies by trim and wheel package. The ES can be found with either 205/65R15 or 215/60R16, while the LS uses 215/60R16. The difference is tied to wheel diameter rather than a simple preference between two sizes.
That means the right tire starts with identifying the exact sub-model and then confirming what wheels are actually on the car today. On a used vehicle, wheel swaps are common enough that the safest approach is to verify the current setup directly instead of assuming every ES or LS still has its original wheel size.
Choosing the Right Tire
What should I consider when choosing a 205/65R15 tire for a 1998 Mitsubishi Diamante?
For a 1998 Mitsubishi Diamante running 205/65R15, the first priorities are correct size, radial construction, and compatibility with the 15-inch wheel setup. Within that size, available choices include BFGoodrich Silvertown Radial tires with either a Wide Whitewall or Redline sidewall, so the main difference is visual presentation rather than a change in fitment category.
The selection process should also include checking the wheel width range, which is 5.50 to 7.50 inches for the available 205/65R15 products. That makes this size especially useful for buyers who want a distinctive appearance on a Diamante while still staying within the proper size format for a 15-inch application.
What sidewall styles are available for 1998 Mitsubishi Diamante tires?
In the available 205/65R15 product range for the 1998 Mitsubishi Diamante, sidewall choices include Wide Whitewall and Redline. Both are offered on the BFGoodrich Silvertown Radial series, so the buyer is choosing between two very different visual treatments on the same basic radial tire format.
That matters most for owners who want the car to lean toward a cleaner restored look or a more customized late-1990s show-style presentation. Sidewall style does not replace the need to confirm the correct tire size and wheel diameter, but it can strongly influence how the finished car looks once fitment is settled.
What brands offer tires for the 1998 Mitsubishi Diamante?
Current product choices for the 1998 Mitsubishi Diamante center on BFGoodrich in the 205/65R15 size. The available offerings are part of the Silvertown Radial line and give buyers a choice of sidewall appearance while staying within the same tire series and radial construction type.
Brand comparison only becomes useful after the tire size has been confirmed, since the Diamante uses both 15-inch and 16-inch fitments. For a 15-inch ES application, BFGoodrich provides the visible choice between whitewall and redline styling, which may be more important to the final decision than brand switching alone.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Mitsubishi Diamante?
A period-style choice for a 1998 Mitsubishi Diamante starts with using the correct size for the car’s wheel setup, either 205/65R15 or 215/60R16. For 15-inch applications, the available BFGoodrich Silvertown Radial options add a more stylized look through Wide Whitewall or Redline sidewall treatments while keeping modern radial construction.
Appearance goals should be weighed against how original or personalized the car is meant to look. If exact historical presentation matters, it is smart to compare the intended tire style against period photos, dealership literature, or marque-specific references rather than assuming any decorative sidewall treatment was original to every Diamante.
Does correct tire fitment matter for a 1998 Mitsubishi Diamante restoration?
Correct tire fitment matters on a 1998 Mitsubishi Diamante restoration because the car uses two different tire and wheel combinations. Choosing between 205/65R15 and 215/60R16 is not just a styling decision; it affects whether the tire matches the wheel diameter and the configuration the car is meant to retain.
A restoration-minded owner should verify trim level, wheel size, and the overall direction of the project before selecting tires. Even when the goal is mainly visual, the finished car looks more coherent when the tire profile, wheel diameter, and sidewall style all suit the specific Diamante setup instead of mixing unrelated fitments.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Mitsubishi Diamante?
Modifications can affect tire fitment on a 1998 Mitsubishi Diamante, especially when wheels have been changed from 15-inch to 16-inch sizes or replaced with aftermarket designs. Suspension changes, altered ride height, or wheel offset differences can also change how much room the tire has at the fender, strut, and steering components.
A modified Diamante should be checked carefully before choosing tires by confirming current wheel diameter, wheel width, and clearance at full steering lock and through suspension travel. That is particularly important on the ES, since it can appear with either original tire size and may no longer reflect its factory-style wheel configuration.
What should I inspect before driving a 1998 Mitsubishi Diamante on new tires?
Before driving a 1998 Mitsubishi Diamante on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and check that the tires are mounted and inflated properly. It is also wise to look over suspension and steering components, since worn parts can affect how a new tire tracks and wears.
A road-ready inspection should include checking for fender and strut clearance, making sure lug hardware is correct, and watching for any rubbing on the first short drive. Older sedans can hide alignment or wheel-balance issues, so paying attention early helps protect the new tires and makes the car feel settled on the road.
How often should tires on a 1998 Mitsubishi Diamante be inspected?
Tires on a 1998 Mitsubishi Diamante should be inspected regularly, especially if the car is driven infrequently or kept as a well-preserved older sedan. Routine checks should include air pressure, tread wear, cracking, bulges, cuts, and any signs of uneven wear that could point to alignment or suspension problems.
Cars that spend long periods parked deserve extra attention because tire aging can develop even when mileage stays low. A quick visual inspection before each drive and a more thorough check at regular intervals can help catch issues early, particularly on a Diamante that may still be riding on older wheels or replacement tire sets.
