The 2007 Mitsubishi Eclipse belongs to the final generation of a sport compact coupe and convertible that carried a strong enthusiast identity into the modern era. Its sharp styling and available performance-focused trim packages make tire choice more than a routine maintenance decision, especially when wheel size changes with the package. This Eclipse uses modern radial fitments in either 225/50R17 or 235/45R18, depending on the exact sub-model. Available tires center on blackwall performance-oriented radial choices from BFGoodrich and Nitto, with several g-Force series options in the mix. The key is matching the correct size to the exact trim and wheel setup before comparing tread character, rim-width compatibility, and intended street use.
Which Tire Size Is Right for The 2007 Mitsubishi Eclipse
The 2007 Mitsubishi Eclipse uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Most GS, GT, Spyder GS, and Spyder GT versions use 225/50R17, while Premium Sport Package versions step up to 235/45R18. Before choosing a tire, confirm whether the car is on 17-inch or 18-inch wheels and make sure the current wheel setup still matches the original package.
225/50R17 is a metric radial size that reads as a 225-millimeter section width, a 50-series aspect ratio, and fitment for a 17-inch rim. On the 2007 Mitsubishi Eclipse, this is the primary size for several coupe and Spyder sub-models, making it the more common fitment across the range. Available choices include blackwall performance radials from BFGoodrich and Nitto, with g-Force and NT555 G2 series options. This size is the right place to focus if your Eclipse retains its 17-inch wheel setup and you want to compare brand, series, and rim-width suitability within the correct fitment.
Fit(s): GT w/Premium Sport Pkg. and Spyder GT w/Premium Sport Pkg.
Construction: Radial|Rim: 18 in
235/45R18 is a metric radial size with a 235-millimeter section width, a 45-series profile, and fitment for an 18-inch rim. On the 2007 Mitsubishi Eclipse, this size is tied to Premium Sport Package versions, so it should not be treated as universal across all trims. Available options are blackwall BFGoodrich performance radials, including multiple g-Force series. This size deserves close attention if the car has the larger factory-style wheel package or if wheel changes have been made and you need to verify that the 18-inch setup is actually what the vehicle is using now.
Tire fitment on the 2007 Mitsubishi Eclipse is straightforward once the exact sub-model and wheel package are confirmed. Most covered sub-models share the 17-inch fitment, while Premium Sport Package versions move to a different tire size on an 18-inch wheel.

2007 Mitsubishi Eclipse GS
The 2007 Mitsubishi Eclipse GS uses the 225/50R17 radial tire size. That keeps selection centered on modern 17-inch performance-oriented blackwall radials, with the main job being to confirm the car still has the correct wheel diameter before comparing product options.
The 2007 Mitsubishi Eclipse GT also uses 225/50R17 radial tires in standard form. Tire selection then comes down to choosing among the available 17-inch performance radial options while making sure the current wheels have not been changed from the original setup.
The 2007 Mitsubishi Eclipse GT w/Premium Sport Pkg. uses the larger 235/45R18 radial fitment. That makes wheel confirmation especially important, since this package changes both tire size and rim diameter compared with the standard GT configuration.
The 2007 Mitsubishi Eclipse Spyder GS uses 225/50R17 radial tires. For selection purposes, the focus stays on correct 17-inch fitment and comparing the available blackwall performance radials for the kind of street use the car sees.
The 2007 Mitsubishi Eclipse Spyder GT shares the 225/50R17 radial size with several other sub-models. That shared fitment makes tire shopping simpler, but it still helps to verify wheel diameter and width before settling on a specific tire series.
2007 Mitsubishi Eclipse Spyder GT w/Premium Sport Pkg.
The 2007 Mitsubishi Eclipse Spyder GT w/Premium Sport Pkg. uses 235/45R18 radial tires rather than the standard 17-inch size. Tire selection should start with confirming that 18-inch wheel package, then comparing the available BFGoodrich performance radial options within that fitment.
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.
Best 2007 Mitsubishi Eclipse Tires for Sale
Available 2007 Mitsubishi Eclipse tire choices center on 17-inch and 18-inch blackwall radial performance tires from BFGoodrich and Nitto. The product grid lets you compare g-Force series options, NT555 G2 fitment, and rim-width specifications within the correct size for your exact sub-model.
Owners of a 2007 Mitsubishi Eclipse usually need to confirm the right tire size by sub-model first, then compare wheel diameter, performance-oriented radial options, and product differences such as brand, series, and rim-width compatibility.
Tire Size & Fitment
What tire size fits a 2007 Mitsubishi Eclipse?
The 2007 Mitsubishi Eclipse uses either 225/50R17 or 235/45R18, depending on the sub-model. GS, GT, Spyder GS, and Spyder GT models use 225/50R17, while GT w/Premium Sport Pkg. and Spyder GT w/Premium Sport Pkg. use 235/45R18.
The practical difference is not just tire width and profile, but wheel diameter. Before selecting tires, confirm the exact trim and check whether the car is still running its original 17-inch or 18-inch wheels, since aftermarket wheel changes can make the current setup different from the original sub-model fitment.
What size rim does a 2007 Mitsubishi Eclipse use?
A 2007 Mitsubishi Eclipse uses either a 17-inch or 18-inch rim, depending on the tire size tied to the sub-model. The 225/50R17 fitment uses a 17-inch rim, and the 235/45R18 fitment uses an 18-inch rim.
That rim diameter needs to match the tire exactly, so the first check should be the wheel itself rather than the old tire alone. It also helps to confirm wheel width before choosing among available tires, since the product options in both sizes have rim-width specifications that should align with the actual wheel on the car.
Do all 2007 Mitsubishi Eclipse sub-models use the same tire size?
No. Most 2007 Mitsubishi Eclipse sub-models use 225/50R17, but Premium Sport Package versions use 235/45R18. That means the GS, GT, Spyder GS, and Spyder GT share one fitment, while the GT w/Premium Sport Pkg. and Spyder GT w/Premium Sport Pkg. use a larger wheel-and-tire combination.
This matters because tire shopping for this Eclipse starts with package identification, not just the model name on the decklid. A GT can be either 17-inch or 18-inch depending on the package, so checking the exact sub-model and wheel diameter prevents choosing a tire that belongs to a different Eclipse configuration.
Choosing the Right Tire
What should I consider when choosing a 2007 Mitsubishi Eclipse tire?
Start with the correct size for the exact sub-model: 225/50R17 or 235/45R18. From there, compare radial construction details that matter to the way the car is used, including tire series, rim-width compatibility, load figures where stated, and whether the tire is geared more toward all-season or sport-oriented driving.
The 2007 Eclipse has a more focused personality than an ordinary commuter coupe, so the tire should match both the wheel setup and the owner’s expectations. A car used mostly for fair-weather driving may lead to a different choice than one that sees regular street miles, even when both are using the same basic size.
What brands offer tires for the 2007 Mitsubishi Eclipse?
Available tires for the 2007 Mitsubishi Eclipse come from BFGoodrich and Nitto. In 225/50R17, choices include BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2, while 235/45R18 fitment includes several BFGoodrich g-Force options.
Brand is only one part of the decision, since the actual fitment, tire series, and wheel compatibility still matter more than the name on the sidewall. It helps to compare products within the correct size first, then look at differences in tread character, stated load capacity, and intended use for the car.
What tire series are available for the 2007 Mitsubishi Eclipse?
The 2007 Mitsubishi Eclipse is offered with several performance-oriented tire series, including BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and the Nitto NT555 G2. Availability depends on whether the car uses the 17-inch or 18-inch fitment.
Series names matter because they help separate an all-season-style option from more explicitly sport-focused choices within the same size range. Once the correct tire size is confirmed, comparing series is a useful way to narrow the field based on how the Eclipse is driven and whether tire behavior or everyday versatility matters more.
Restoration & Appearance
Which tire should I choose for a period-style 2007 Mitsubishi Eclipse?
A period-style approach for a 2007 Mitsubishi Eclipse starts with keeping the correct original-size format for the exact sub-model, whether that is 225/50R17 or 235/45R18. Since the available choices are modern blackwall radials, the visual character stays in line with the Eclipse’s factory-era sport compact appearance.
For an appearance-focused build, matching the proper wheel diameter and avoiding an unintended change in profile usually matters more than chasing unusual styling cues. Owners seeking exact showroom-era detail should also compare the car against original window sticker information, marque references, or period photography before making a final selection.
Does correct tire fitment matter for a 2007 Mitsubishi Eclipse restoration?
Yes, correct tire fitment matters because the 2007 Mitsubishi Eclipse used two different wheel-and-tire packages depending on sub-model. A restoration-minded car looks and sits differently when the original 17-inch setup is replaced with an 18-inch package, or the reverse.
Keeping the proper size helps preserve the intended stance and proportions of the car, especially on Premium Sport Package versions that were built around the larger fitment. Even on a driver-quality restoration, confirming the right size before purchase is one of the simplest ways to keep the finished car visually coherent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2007 Mitsubishi Eclipse?
Yes. A 2007 Mitsubishi Eclipse may no longer match its original tire fitment if it has aftermarket wheels, suspension changes, altered ride height, or body modifications. That matters especially on this model because the original fitment already varies between 17-inch and 18-inch setups depending on the sub-model and package.
The safest approach is to verify the actual wheel diameter and width on the car before choosing tires. Clearance at the fender, strut, and steering range should also be checked any time the wheel or suspension setup has been changed, even when the tire size sounds close to the original specification.
What should I inspect before driving a 2007 Mitsubishi Eclipse on new tires?
Before putting a 2007 Mitsubishi Eclipse back into regular road use on new tires, inspect wheel condition, valve stems, alignment-related wear patterns, and the basic condition of suspension and steering components. Tire pressure should be set correctly, and the wheel hardware should be in proper condition before the car is driven any distance.
A fresh set of tires cannot compensate for bent wheels, worn suspension parts, or poor alignment. It is also worth checking for rubbing at full steering lock and over suspension movement, particularly if the car has aftermarket wheels or if an 18-inch Premium Sport Package setup has been changed from its original configuration.
How often should tires on a 2007 Mitsubishi Eclipse be inspected?
Tires on a 2007 Mitsubishi Eclipse should be inspected regularly, not just when tread looks low. Check them for uneven wear, sidewall damage, punctures, cracking, bulges, and slow air loss, especially if the car is driven seasonally or sits for long stretches between outings.
Low-use sporty cars can develop tire issues that are easy to miss because mileage accumulates slowly. A quick inspection before routine drives and a more careful check before longer trips helps catch age-related deterioration, pressure loss, or clearance problems early, which is especially useful on cars running lower-profile performance tire fitments.
