The 2008 Mitsubishi Eclipse came from the final years of the model’s modern front-wheel-drive performance era, when bold styling and a sport-compact image still shaped the car’s appeal. Coupe and Spyder versions gave buyers different personalities, but tire fitment stayed closely tied to trim level and wheel package. This Eclipse uses modern radial sizing, with 225/50R17 on 17-inch wheels or 235/45R18 on 18-inch wheels depending on the sub-model. Available choices center on Blackwall performance-oriented radials from BFGoodrich and Nitto across several g-Force and NT555 series options. The key is matching the exact sub-model and wheel diameter before comparing ride character, sizing details, and product construction within the correct fitment.
Which Tire Size Is Right for The 2008 Mitsubishi Eclipse
Two primary tire sizes apply to the 2008 Mitsubishi Eclipse, and the right one depends on the specific sub-model and wheel diameter. GS and Spyder GS models use a 17-inch fitment, while GT, SE, SE V6, and Spyder GT models use an 18-inch fitment. Before comparing tires, confirm which sub-model you have and verify that the car still has the correct wheel size.
225/50R17 is a metric radial size in which 225 indicates section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2008 Mitsubishi Eclipse, this size is used on the 17-inch wheel fitment rather than the larger-wheel trims. Product choices in this size include Blackwall radials from BFGoodrich and Nitto in series such as g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2. It is the size to evaluate when matching GS or Spyder GS fitment and comparing performance-oriented street tire options.
235/45R18 is a metric radial size with a 235-millimeter nominal section width, a 45-series profile, radial construction, and an 18-inch wheel diameter. This fitment belongs to the larger-wheel 2008 Mitsubishi Eclipse configurations, including GT, SE, SE V6, and Spyder GT models. Available choices are Blackwall radials from BFGoodrich, including the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. It is the correct starting point for buyers whose Eclipse is equipped with the 18-inch setup and who want to compare tire character within the proper size.
Tire fitment on the 2008 Mitsubishi Eclipse varies by sub-model rather than staying uniform across the lineup. Checking the exact trim matters because the car uses either a 17-inch or 18-inch wheel package, and that changes the correct tire size from the start.

2008 Mitsubishi Eclipse GS
The 2008 Mitsubishi Eclipse GS uses the 17-inch radial fitment rather than the larger 18-inch setup used on other trims. That makes wheel confirmation especially important before comparing BFGoodrich and Nitto options in the correct size.
The 2008 Mitsubishi Eclipse GT uses the 18-inch radial fitment shared with several higher-spec Eclipse variants. Tire selection here centers on staying with the proper larger-wheel size and then comparing available BFGoodrich product series within that fitment.
The 2008 Mitsubishi Eclipse SE uses the 18-inch radial tire size rather than the 17-inch fitment found on GS models. Buyers should confirm that the car still carries its matching wheel package before narrowing choices by tire series and specification.
The 2008 Mitsubishi Eclipse SE V6 follows the 18-inch radial fitment used on the upper Eclipse configurations. The practical step is to confirm wheel diameter first, then compare the available Blackwall performance tire choices in the proper size.
The 2008 Mitsubishi Eclipse Spyder GS uses the same 17-inch radial fitment as the GS coupe. That keeps tire selection straightforward as long as the convertible still has the correct wheel size and has not been changed to an aftermarket setup.
The 2008 Mitsubishi Eclipse Spyder GT uses the 18-inch radial fitment shared with the GT and SE-based coupe models. Tire choice depends on keeping that larger-wheel sizing straight before comparing available series and rim-width compatibility.
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.

Owners usually need to confirm the exact Eclipse sub-model first, then sort out wheel diameter, tire size, and the differences between available radial tire lines. These answers focus on fitment, product choice, appearance, and basic road-use checks for a 2008 Mitsubishi Eclipse.
Tire Size & Fitment
What tire size fits a 2008 Mitsubishi Eclipse?
A 2008 Mitsubishi Eclipse uses one of two tire sizes: 225/50R17 or 235/45R18. The 225/50R17 size belongs to the GS and Spyder GS, while the 235/45R18 size is used on the GT, SE, SE V6, and Spyder GT.
The practical difference is that these sizes are tied to different wheel diameters, so the first step is confirming the exact sub-model and checking the wheels currently on the car. An Eclipse with aftermarket wheels or a previous tire swap may no longer match its original trim-based setup.
What size rim does a 2008 Mitsubishi Eclipse use?
The 2008 Mitsubishi Eclipse uses either a 17-inch or 18-inch rim, depending on sub-model. GS and Spyder GS models use the 17-inch fitment, while GT, SE, SE V6, and Spyder GT models use the 18-inch fitment.
Rim diameter needs to match the tire exactly, so a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is also true. It is worth checking the wheel itself before ordering tires, especially if the car has changed hands or has been modified since new.
Why does the 2008 Mitsubishi Eclipse have more than one tire size?
The 2008 Mitsubishi Eclipse has more than one tire size because the lineup was split by sub-model and wheel package. Some versions use 225/50R17 on 17-inch wheels, while others use 235/45R18 on 18-inch wheels.
That means tire selection is not just a year-and-model question. The buyer needs to identify the exact trim and confirm the wheel diameter on the car now, since a GS-sized tire and a GT-sized tire are not interchangeable simply because they belong to the same model year.
Choosing the Right Tire
What should I consider when choosing a 2008 Mitsubishi Eclipse tire?
Start with the correct size for the sub-model: 225/50R17 for GS and Spyder GS, or 235/45R18 for GT, SE, SE V6, and Spyder GT. From there, compare radial tire construction, rim-width compatibility, load figures where stated, and the intended street use of the car.
A mostly stock Eclipse used for regular warm-weather driving may be chosen differently than one kept for occasional use or one already fitted with aftermarket wheels. Looking at tire series, sidewall treatment, and the wheel width on the car will help narrow the right option without drifting away from the correct fitment.
What brands offer tires for the 2008 Mitsubishi Eclipse?
Available tires for the 2008 Mitsubishi Eclipse come from BFGoodrich and Nitto. In the 17-inch fitment, BFGoodrich and Nitto both appear, while the 18-inch fitment shown here centers on BFGoodrich options.
Brand alone should not make the decision. It helps to compare the exact tire series, the wheel-width range the tire is built around, and any stated load specification that applies to your size. Those details matter more than the badge when matching a tire to the car’s current wheel setup.
What tire series are available for the 2008 Mitsubishi Eclipse?
The 2008 Mitsubishi Eclipse is supported here by several radial tire series, including BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, BFGoodrich g-Force Phenom T/A, and Nitto NT555 G2. Availability depends on whether the car uses the 17-inch or 18-inch fitment.
Series names matter because they help separate one product from another even when the tire size is the same. Once the correct size is confirmed, the useful comparison points are the specific series, the rim-width range, and any load or weight details that influence how the tire suits the wheel and intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Mitsubishi Eclipse?
A period-style 2008 Mitsubishi Eclipse should begin with the correct original fitment type for the sub-model, which means 225/50R17 on GS-based cars or 235/45R18 on GT and SE-based cars. Since the available choices are modern Blackwall radials, the appearance stays in line with the Eclipse’s late sport-compact era.
The main restoration-minded decision is less about vintage sidewall treatment and more about keeping the right wheel diameter and overall visual balance for the trim. Buyers who care about exact presentation should also confirm the car still wears the proper wheel style and size before selecting a replacement tire.
Does correct tire fitment matter for a 2008 Mitsubishi Eclipse restoration?
Correct tire fitment matters on a 2008 Mitsubishi Eclipse restoration because the model used distinct 17-inch and 18-inch packages depending on trim. Using the proper size helps preserve the stance, wheel-to-tire proportion, and overall visual character that belongs with that specific version of the car.
The effect is not only cosmetic. A mismatch in tire size can also complicate wheel fit, fender clearance, and the way the car sits on the road. Anyone restoring an Eclipse to a trim-appropriate appearance should confirm both the sub-model and the actual wheels on the vehicle before choosing tires.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Mitsubishi Eclipse?
Yes, modifications can affect tire fitment on a 2008 Mitsubishi Eclipse. Aftermarket wheels, lowered suspension, alignment changes, or body modifications can alter the space available around a 225/50R17 or 235/45R18 tire even when the nominal size still sounds correct.
The safest approach is to verify the actual wheel diameter and width on the car, then check clearance at the fender, strut, and steering range before changing tires. A modified Eclipse should be measured as it sits now rather than assumed to follow the original trim-based fitment without issue.
What should I inspect before driving a 2008 Mitsubishi Eclipse on new tires?
Before driving a 2008 Mitsubishi Eclipse on new tires, inspect the wheels for damage, confirm the tire size matches the rim diameter, and check that inflation is set correctly for the installation. It also helps to look over the valve stems, wheel hardware, and general condition of the suspension and alignment.
A quick road-use check should include watching for vibration, rubbing, or a pull at the steering wheel once the car is moving. Any sign of uneven clearance or contact deserves attention immediately, especially on an Eclipse that may have non-stock wheels or suspension parts.
What should I check before a longer drive in a 2008 Mitsubishi Eclipse?
Before a longer drive in a 2008 Mitsubishi Eclipse, check tire pressure, tread condition, and the sidewalls for cracks, cuts, or bulges. It is also smart to confirm that all four tires are the correct size for the car’s wheel package and that there is no slow air loss.
Longer trips put more heat and distance into the tires, so an Eclipse that spends much of its time parked still deserves a careful inspection before heading out. Looking over alignment wear, wheel balance behavior, and general clearance can prevent small fitment or maintenance issues from becoming larger problems on the road.
