The 2018 Mitsubishi Mirage is a modern subcompact built around efficiency, easy urban maneuverability, and low running costs rather than oversized wheel and tire packages. For owners, that makes correct tire selection less about chasing dramatic upgrades and more about matching the car’s exact trim and wheel setup. This model uses two primary radial tire sizes, 165/65R14 and 175/55R15, depending on sub-model. The choice is straightforward once the trim and rim diameter are confirmed, but the available setup still affects ride character, appearance, and everyday drivability. Checking the car’s actual wheels before ordering is especially important if anything has been changed over time.
Which Tire Size Is Right for The 2018 Mitsubishi Mirage
The 2018 Mitsubishi Mirage uses two primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. Both are radial sizes, but one fits a 14-inch rim and the other fits a 15-inch rim, so the first step is confirming whether the car is an ES, SE, or GT and verifying the wheels currently on the vehicle.
The 165/65R14 size is a metric radial format: 165 identifies the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 2018 Mitsubishi Mirage, this size supports the smaller-wheel fitment used on certain sub-models. Its overall dimensions make it part of the car’s intended compact, economical setup rather than a styling-driven package. This is the size to evaluate when matching an ES or SE wheel package or when confirming that a 14-inch wheel remains on the car.
The 175/55R15 size is also a metric radial, with a 175-millimeter nominal section width, a 55-series profile, radial construction, and a 15-inch rim diameter. On the 2018 Mitsubishi Mirage, this size belongs to the larger-wheel fitment used on the GT sub-model. Compared with the 14-inch setup, the key distinction for the buyer is wheel diameter first, not just the printed tire code. This is the size to focus on when the car carries its 15-inch wheel package and the goal is to preserve the intended trim-specific fitment.
Tire fitment on the 2018 Mitsubishi Mirage varies by sub-model, so identifying the exact trim matters before choosing a replacement. ES and SE share one tire size, while GT uses a different size on a different rim diameter.

2018 Mitsubishi Mirage ES
The 2018 Mitsubishi Mirage ES uses the 165/65R14 radial tire size. That keeps tire selection centered on maintaining the correct 14-inch fitment and confirming that the car still has its original wheel diameter before replacement.
The 2018 Mitsubishi Mirage GT uses the 175/55R15 radial tire size. Tire selection for the GT starts with confirming the 15-inch wheel setup, since this trim does not share the smaller 14-inch fitment used on other Mirage sub-models.
The 2018 Mitsubishi Mirage SE uses the 165/65R14 radial tire size. That gives the SE the same basic tire-fitment path as the ES, with the main priority being correct 14-inch wheel matching rather than deciding between multiple primary sizes.
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.
Frequently Asked Questions
Owners of a 2018 Mitsubishi Mirage usually need to sort out trim-specific tire size, 14-inch versus 15-inch wheel fitment, and practical replacement checks. These FAQs focus on exact size selection, tire choice, and everyday road-use inspection points for this model.
Tire Size & Fitment
What tire size fits a 2018 Mitsubishi Mirage?
A 2018 Mitsubishi Mirage uses one of two radial tire sizes: 165/65R14 or 175/55R15. The correct size depends on the sub-model, with ES and SE using 165/65R14 and GT using 175/55R15.
That means the first step is identifying the exact trim and checking the wheel diameter currently on the car. A Mirage that has had wheels changed over time may no longer match its original sub-model setup, so the tire size on the sidewall and the actual rim size should both be confirmed before replacement.
What size rim does a 2018 Mitsubishi Mirage use?
The 2018 Mitsubishi Mirage uses either a 14-inch or 15-inch rim, depending on sub-model. The 165/65R14 tire fits the 14-inch setup, while the 175/55R15 tire fits the 15-inch setup.
Rim diameter is the key fitment checkpoint because a 14-inch tire cannot be mounted on a 15-inch wheel, and the reverse is also true. Looking at the current tire sidewall and measuring only if needed is usually enough to confirm which wheel package the car has before choosing a replacement tire.
Do all 2018 Mitsubishi Mirage sub-models use the same tire size?
No. The 2018 Mitsubishi Mirage ES and SE use 165/65R14, while the GT uses 175/55R15. All of them use radial tires, but they do not all share the same wheel and tire package.
That difference matters because the GT’s 15-inch fitment should not be treated as interchangeable with the 14-inch setup used on ES and SE. Buyers should verify the sub-model and the actual wheels on the vehicle, especially if the car was purchased used or has had replacement wheels installed at some point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Mitsubishi Mirage?
Start with the correct size for the exact trim: 165/65R14 for ES and SE, or 175/55R15 for GT. Since both primary fitments are radial, the main decision is not construction type but matching the proper size and rim diameter to the car.
From there, compare the tire’s intended use with how the Mirage is driven, whether that means city commuting, occasional highway use, or low-mileage service. Wheel diameter, current wheel condition, and any previous modifications should be checked so the replacement tire matches the vehicle’s present setup rather than just the model name.
How do I choose between the available tires for a 2018 Mitsubishi Mirage?
The best way to narrow the choice is to confirm the correct trim-specific size first, then compare tires within that exact size. For a 2018 Mitsubishi Mirage, that means staying within either 165/65R14 or 175/55R15 rather than mixing the two fitments.
Once size is settled, think about how original the wheel package remains and whether the car is used daily or only occasionally. A careful comparison should center on the tire’s dimensions, compatibility with the existing wheel, and the kind of service the car actually sees, instead of assuming every same-size tire will suit the vehicle equally.
What rim-fitment details matter when choosing 2018 Mitsubishi Mirage tires?
The most important rim-fitment detail is diameter: the 2018 Mitsubishi Mirage uses either a 14-inch or 15-inch wheel depending on trim. A tire must match that wheel diameter exactly, so 165/65R14 belongs with the 14-inch setup and 175/55R15 belongs with the 15-inch setup.
Wheel condition and actual wheel specification also matter, especially on a used car. If the Mirage has aftermarket wheels, a previous owner may have changed the original setup, so it is smart to confirm the current wheel size and inspect for clearance around suspension and body components before choosing a replacement tire.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Mitsubishi Mirage restoration or refresh?
Yes. Even on a newer compact car like the 2018 Mitsubishi Mirage, keeping the correct trim-specific tire size helps preserve the intended stance, wheel proportion, and everyday driving character. ES and SE use 165/65R14, while GT uses 175/55R15, so the visual presentation changes with the wheel package.
A cosmetic refresh or careful preservation project benefits from matching the tire to the wheel setup the car actually carries. Before replacing tires for appearance reasons, confirm that the current wheels are the correct diameter for the trim so the finished look remains consistent rather than accidentally mixing GT and non-GT fitment.
How does tire size affect the appearance of a 2018 Mitsubishi Mirage?
Tire size has a noticeable effect because the 2018 Mitsubishi Mirage uses two different wheel diameters across its sub-models. The 165/65R14 setup gives the car its 14-inch wheel presentation, while the 175/55R15 setup changes the visual balance by pairing the Mirage with a 15-inch wheel.
That does not make one look inherently better than the other, but it does mean appearance is tied closely to trim and wheel choice. Owners trying to keep a Mirage looking consistent should match the tire size to the wheel package already on the car and avoid assuming all sub-models shared one uniform setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mitsubishi Mirage?
Yes. A 2018 Mitsubishi Mirage that has aftermarket wheels, altered suspension height, or body changes may no longer follow its original trim-based tire setup. Even though the factory fitments are 165/65R14 and 175/55R15, changes to the car can affect which tire size is currently appropriate.
The practical step is to inspect the actual wheel diameter and look for clearance around the fenders, struts, and steering components before replacing tires. Modifications do not automatically create a problem, but they do make it more important to verify the car’s present configuration instead of relying only on the factory sub-model listing.
What should I inspect before driving a 2018 Mitsubishi Mirage on new tires?
Before road use, inspect the wheels for damage, confirm the new tires match the correct trim-specific size, and check that inflation is set properly for the vehicle. It is also wise to look over the valve stems, lug torque, and general mounting condition after installation.
A short clearance check can prevent surprises, especially during full steering lock or over bumps. Owners should also pay attention to vibration, pull, or uneven feel during the first drive, since those signs can point to balance issues, alignment concerns, or a mismatch between the tire chosen and the wheel setup on the car.
How often should tires on a 2018 Mitsubishi Mirage be inspected?
Tires on a 2018 Mitsubishi Mirage should be inspected regularly, not just when tread looks low. Routine checks for air loss, cuts, bulges, irregular wear, and sidewall damage are especially important on a compact car where small tire changes can affect ride quality and day-to-day drivability.
A monthly pressure and condition check is a sensible habit, with another inspection before longer drives or after road impacts. Cars that sit for extended periods still need attention, because age, storage conditions, and underinflation can affect a tire even when mileage stays low.
