2010 Mitsubishi Eclipse Tires

The 2010 Mitsubishi Eclipse uses two tire sizes: 225/50R17 and 235/45R18. The 225/50R17 size applies to the GS and Spyder GS, while the 235/45R18 size applies to the GS Sport, GT, and Spyder GT. Both are radial tire fitments tied to specific sub-model and wheel setups.

The practical step is identifying the exact trim and confirming the wheel diameter actually on the car. A used Eclipse may have aftermarket wheels or a replacement wheel set, so matching the tire to both the sub-model and the current 17-inch or 18-inch rim is more important than assuming every 2010 Eclipse uses the same size.

A 2010 Mitsubishi Eclipse uses either a 17-inch or 18-inch rim, depending on sub-model. The 225/50R17 tire size uses a 17-inch rim, while the 235/45R18 tire size uses an 18-inch rim. Rim diameter is part of the tire size itself, so the tire and wheel must match at that point.

Checking the wheel diameter on the car is the first fitment step before comparing brands or tire series. Even if the sub-model originally used one setup, wheel swaps are common, and a 17-inch tire cannot be mounted on an 18-inch rim. Wheel width should also be reviewed when comparing product options in the correct size.

No. The 2010 Mitsubishi Eclipse uses different tire sizes across its sub-model range. GS and Spyder GS models use 225/50R17, while GS Sport, GT, and Spyder GT models use 235/45R18. The difference is tied to the trim level and its wheel diameter rather than a simple universal fitment across the whole model line.

That split means tire selection should start with the exact sub-model name, then move to the wheel size currently installed. This is especially important on cars that have changed hands or seen cosmetic upgrades, because a tire decision based only on the model year and name can miss the actual 17-inch or 18-inch setup.

Start with the correct tire size for the exact sub-model: 225/50R17 or 235/45R18. From there, compare radial construction details such as the tire series, wheel-width compatibility, load figures where shown, and whether the tire suits the way the car is used, from routine street driving to more spirited road use.

Appearance is simpler here because the available choices are blackwall tires, so the bigger differences are in the product line and wheel match. It also helps to verify that the car still has the intended wheel diameter and width, since an Eclipse with aftermarket wheels may narrow the field of appropriate choices within the correct size.

BFGoodrich and Nitto offer tires for the 2010 Mitsubishi Eclipse in the sizes covered here. The 225/50R17 fitment includes BFGoodrich and Nitto options, while the 235/45R18 fitment is represented by BFGoodrich products. All of the available choices are radial blackwall tires aimed at a modern performance-oriented presentation.

Brand choice should be part of a broader comparison rather than the only deciding factor. Looking at the correct size first, then reviewing tire series, rim-width range, load information where shown, and intended use will do more to narrow the field than choosing solely by brand name on a car with trim-specific tire fitment.

Available tire series for the 2010 Mitsubishi Eclipse include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. The exact series available depends on whether the car uses the 225/50R17 or 235/45R18 tire size tied to its sub-model.

Comparing tire series is useful once the correct size is confirmed, because series differences help separate one radial option from another within the same fitment. The smartest approach is to keep size and wheel compatibility fixed first, then compare the series that remain and decide which one best matches the car’s current use and setup.

A period-style choice for a 2010 Mitsubishi Eclipse starts with using the proper original-format size for the sub-model, either 225/50R17 or 235/45R18, and staying with a radial tire. Since the available products here are blackwall performance-oriented tires, they suit the modern sporty look that matches the Eclipse’s late-model character.

The main visual decision is less about vintage sidewall treatment and more about preserving the car’s intended stance through the correct wheel diameter and profile. A 17-inch GS or Spyder GS should not be approached the same way as an 18-inch GS Sport, GT, or Spyder GT, especially if appearance and proportions matter to the final result.

Yes, correct tire fitment matters because the 2010 Mitsubishi Eclipse uses two different size and rim-diameter combinations across its sub-model lineup. Using the proper 225/50R17 or 235/45R18 setup helps preserve the car’s intended proportions and keeps the wheel-and-tire package aligned with the trim it belongs to.

That becomes especially important on cars that have been modified, repainted, or returned toward stock appearance after years of use. Correct fitment does not automatically make a restoration historically exact, but it does provide the right starting point. For owners chasing high-level originality, trim-specific references and marque-focused documentation are worth consulting.

Yes. A 2010 Mitsubishi Eclipse can be affected by wheel, suspension, or ride-height changes even when the tire size appears close to stock. Aftermarket wheels may change width or offset, and suspension modifications can alter fender and steering clearance. That matters on a car that already uses two different factory size and rim-diameter combinations.

The safest approach is to verify the actual wheel diameter, wheel width, and clearances on the car before selecting replacement tires. A GS on 17-inch wheels and a GT on 18-inch wheels should be treated differently, and any lowered or customized Eclipse deserves a careful check at full lock and under normal driving load.

Inspect the wheels for damage, verify the tire size matches the car’s actual rim diameter, and look over alignment-sensitive wear points such as suspension components and steering parts. Tire condition should also be checked closely, including air pressure, bead seating, sidewall condition, and any visible cuts or irregularities after installation.

A short road test should confirm that the tires clear the fenders and suspension without rubbing and that the car tracks normally. On a 2010 Eclipse, this matters even more if the car has replacement wheels, because the difference between the 17-inch and 18-inch fitments leaves less room for assumptions during a new-tire change.

Tires on a 2010 Mitsubishi Eclipse should be inspected regularly, not just at major service intervals. A quick visual check for uneven tread wear, sidewall cracking, punctures, bulges, and air loss is worthwhile before routine driving, and a more thorough inspection should happen anytime the car’s handling or ride changes noticeably.

Cars in this age range often spend periods parked, and that can hide problems until the next drive. It helps to monitor pressure, look for age-related deterioration, and confirm that wear remains even across the tread. Paying attention early is especially useful on a sporty coupe or convertible where wheel changes and enthusiastic driving are both common.
