The 2020 Mitsubishi Mirage is a modern subcompact built around efficiency, easy maneuverability, and low operating costs rather than oversized wheels or aggressive tire fitments. That makes exact tire selection especially important, because small changes in size can noticeably affect the way the car looks and drives. This Mirage uses one of two primary radial tire sizes, 165/65R14 or 175/55R15, depending on the sub-model and wheel diameter. The key decision is not bias-ply versus radial, but confirming whether the car is equipped with the 14-inch or 15-inch setup. Once that is settled, the focus shifts to matching the correct size to the trim and verifying the actual wheel package on the car.
Which Tire Size Is Right for The 2020 Mitsubishi Mirage
Two tire sizes apply to the 2020 Mitsubishi Mirage, and they are tied to sub-model and wheel diameter rather than interchangeable versions of the same fitment. The first step is identifying the exact trim and confirming whether the car has 14-inch or 15-inch wheels. Once that is clear, the decision becomes choosing the correct modern radial size for the vehicle's current wheel setup.
165/65R14 is a metric radial size in which 165 identifies the nominal section width in millimeters, 65 is the aspect ratio, R designates radial construction, and 14 is the wheel diameter in inches. On the 2020 Mitsubishi Mirage, this size belongs to the 14-inch wheel fitment used on specific sub-models rather than across the full range. Its overall dimensions suit the Mirage's compact footprint and economy-focused setup. This is the size to use when the car is equipped with the matching 14-inch wheels and has not been changed to another wheel package.
175/55R15 is a metric radial size where 175 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 15 identifies the wheel diameter in inches. On the 2020 Mitsubishi Mirage, this size is used on sub-models equipped with the 15-inch setup. It is a separate primary fitment, not an upgrade path that should be assumed for every Mirage. This is the size to evaluate when the car carries the correct 15-inch wheels and the trim was built around that wheel and tire combination.
Tire fitment on the 2020 Mitsubishi Mirage varies by sub-model, so trim identification matters before choosing a tire. The ES and SE use one radial size, while the GT and LE use another tied to a different wheel diameter.

2020 Mitsubishi Mirage ES
The 2020 Mitsubishi Mirage ES uses the 165/65R14 radial fitment. Tire selection starts with keeping the 14-inch wheel setup in mind and confirming that the car has not been switched to a different wheel and tire package.
The 2020 Mitsubishi Mirage GT uses the 175/55R15 radial fitment. That makes wheel diameter a key part of tire selection, especially if the car has seen aftermarket wheel changes or a replacement wheel from another trim.
The 2020 Mitsubishi Mirage LE uses the 175/55R15 radial fitment. Choosing tires for this sub-model means matching the 15-inch wheel package correctly and checking the actual wheels on the car before assuming fitment from model year alone.
The 2020 Mitsubishi Mirage SE uses the 165/65R14 radial fitment. The practical goal is to stay with the correct 14-inch size and verify the present wheel setup if the car has had wheel, trim, or appearance changes.
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
Common questions for the 2020 Mitsubishi Mirage usually come down to the right tire size for each trim, 14-inch versus 15-inch wheel fitment, and what to inspect before replacing tires on a small modern hatchback.
Tire Size & Fitment
What tire size fits a 2020 Mitsubishi Mirage?
The 2020 Mitsubishi Mirage uses two primary tire sizes: 165/65R14 and 175/55R15. The 165/65R14 size applies to the ES and SE, while the GT and LE use 175/55R15. Both are radial tire sizes, but they are tied to different trims and different wheel diameters.
The important step is matching the tire to the exact sub-model and the wheels actually on the car. A Mirage that has had wheel replacement, trim swapping, or aftermarket changes should be checked in person so the tire size, wheel diameter, and physical clearance all stay consistent with the current setup.
What size rim does a 2020 Mitsubishi Mirage use?
A 2020 Mitsubishi Mirage uses either a 14-inch or 15-inch rim, depending on sub-model. The 165/65R14 tire fits the 14-inch setup used on the ES and SE, while the 175/55R15 tire fits the 15-inch setup used on the GT and LE.
Rim diameter should be confirmed before any tire purchase, because a 14-inch tire cannot be mounted on a 15-inch wheel and vice versa. Checking the current wheel package is especially worthwhile on cars that may have received used replacement wheels, accessory wheels, or a wheel and tire package carried over from another Mirage trim.
Why does the 2020 Mitsubishi Mirage have more than one tire size?
The 2020 Mitsubishi Mirage has more than one tire size because tire fitment changes with the trim level and wheel package. ES and SE models use 165/65R14, while GT and LE models use 175/55R15. Those sizes correspond to different wheel diameters rather than optional versions of the same exact setup.
That means the right choice is determined by the sub-model first and the wheel on the car second. Buyers should not assume that any Mirage tire will work across the full model range, especially when selecting replacements for a car that may have had wheel changes during routine service or prior ownership.
Choosing the Right Tire
What should I consider when choosing a 165/65R14 or 175/55R15 tire for a 2020 Mitsubishi Mirage?
Start with the correct size for the exact trim and wheel diameter. A 2020 Mitsubishi Mirage ES or SE uses 165/65R14, while a GT or LE uses 175/55R15. Staying with the correct radial size keeps the tire matched to the wheel package the car was built around.
After size is confirmed, compare the actual wheel setup on the car and look at overall condition and intended use. A Mirage driven mainly in city traffic may have different priorities than one used for regular highway commuting, but neither situation changes the need to begin with the proper size and wheel diameter.
How do I choose between the available 2020 Mitsubishi Mirage tire sizes if I am not sure which trim I have?
The two Mirage tire sizes are not alternatives to choose between by preference alone. They are trim-specific fitments: 165/65R14 for ES and SE, and 175/55R15 for GT and LE. The correct choice comes from identifying the sub-model and confirming the wheel diameter already on the car.
A quick trim badge check helps, but the wheel itself should still be verified before replacement. Cars sometimes receive different wheels over time, and a used Mirage may not still wear its original package. Matching the tire to the actual wheel avoids ordering the wrong diameter even when the trim seems straightforward.
Why is wheel confirmation important when choosing tires for a 2020 Mitsubishi Mirage?
Wheel confirmation matters because the 2020 Mitsubishi Mirage uses two distinct tire and rim combinations. One group of trims uses a 14-inch wheel with 165/65R14 tires, while another uses a 15-inch wheel with 175/55R15 tires. The tire size is locked to that wheel diameter.
This step becomes even more important on a small car where packaging is tight and replacement choices are specific. A Mirage with swapped wheels, a missing original wheel, or mixed used parts can easily create confusion, so checking the current wheel size before buying tires prevents a basic but costly fitment mistake.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Mitsubishi Mirage restoration or appearance refresh?
Correct tire fitment still matters on a 2020 Mitsubishi Mirage, even though it is a modern car rather than a vintage restoration project. Using the proper 165/65R14 or 175/55R15 size keeps the car visually balanced with its intended wheel package and avoids an appearance that looks mismatched or improvised.
For an owner freshening up the car cosmetically, the best starting point is the exact trim-specific size and wheel diameter. That preserves the overall stance and proportion of the Mirage more effectively than guessing across sizes, especially on a subcompact where a small dimensional change is easier to notice.
How does tire size affect the look of a 2020 Mitsubishi Mirage?
Tire size has a noticeable effect on the look of a 2020 Mitsubishi Mirage because the car is small and its wheel openings are compact. The 165/65R14 and 175/55R15 sizes create different visual relationships between sidewall height, wheel diameter, and the car's overall stance.
Keeping the correct trim-specific size helps the Mirage retain a tidy, proportional appearance instead of looking under-tired or awkwardly altered. Owners considering replacement wheels should compare the full wheel-and-tire package carefully, since even modest size changes can stand out more on this type of compact hatchback.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Mitsubishi Mirage?
Yes, modifications can affect tire fitment on a 2020 Mitsubishi Mirage. Wheel changes, suspension lowering, non-original offsets, and trim-to-trim wheel swaps can all change what tire size works properly on the car, even when the model year itself points to one of the two original Mirage fitments.
That is why the current wheel diameter and the actual space around the tire should be checked before replacement. Clearance at the fender, inner wheelhouse, and steering components matters more once the car has been altered, and those checks become especially important when the Mirage no longer carries its original wheels.
What should I inspect before driving a 2020 Mitsubishi Mirage on new tires?
Before driving a 2020 Mitsubishi Mirage on new tires, inspect the wheel size, verify the tire size matches the trim, and make sure the tires were mounted correctly and inflated properly. It is also wise to look over the wheels themselves for bends, curb damage, or anything that could affect sealing or balance.
A short road check should include watching for vibration, pull, rubbing, or unusual noise. On a compact car like the Mirage, improper size or wheel mismatch can show up quickly, so catching any issue early helps protect the tires and confirms that the replacement setup is working as intended.
How often should tires on a 2020 Mitsubishi Mirage be inspected?
Tires on a 2020 Mitsubishi Mirage should be inspected regularly, not just when tread looks worn. Pressure, tread wear pattern, cuts, punctures, sidewall damage, and air loss are all worth checking, especially because a lightweight subcompact can feel different quickly when one tire starts to fall out of spec.
Monthly checks are a sensible routine, with an extra inspection before longer drives or seasonal changes in temperature. Any Mirage that has sat for extended periods should also be reviewed for flat spotting, age-related cracking, and uneven wear, since even a lightly used car can develop tire issues over time.
