The 2018 Mitsubishi Mirage G4 is a subcompact sedan built around light weight, city-friendly dimensions, and practical everyday economy. Its appeal is straightforward transportation with a footprint that suits tight urban driving while still offering the separate trunk and sedan profile many drivers prefer. Tire selection centers on two primary radial sizes, 165/65R14 and 175/55R15, and the right choice depends on the exact trim and wheel setup on the car. That makes this page less about broad tire theory and more about confirming whether your Mirage G4 is on 14-inch or 15-inch wheels before comparing replacement options and overall tire style.
Which Tire Size Is Right for The 2018 Mitsubishi Mirage G4
The 2018 Mitsubishi Mirage G4 uses two primary tire sizes, and they are tied to wheel diameter and sub-model configuration. The first step is confirming whether the car has 14-inch or 15-inch wheels, then matching that to the correct size for the exact trim, since the ES can use either size while the SE uses the 15-inch fitment.
The 165/65R14 size reads as a 165-millimeter-wide radial tire with a 65-series aspect ratio for a 14-inch wheel. On the 2018 Mitsubishi Mirage G4, this is a modern radial fitment that suits the car's compact, economy-focused design and keeps the selection tied to the correct 14-inch rim. Its dimensions make it distinct from the 15-inch alternative, so wheel confirmation matters before ordering. This size is especially important for Mirage G4 owners who want to stay with the 14-inch setup rather than moving into the larger-wheel fitment used elsewhere in the lineup.
The 175/55R15 size indicates a 175-millimeter-wide radial tire with a 55-series profile built for a 15-inch wheel. For the 2018 Mitsubishi Mirage G4, this is the other primary fitment and it applies wherever the car is equipped with the 15-inch wheel package. The lower profile and different rim diameter mean it should be treated as a separate fitment choice rather than a casual substitute for the 14-inch size. This is the size to evaluate when the car is an SE or an ES already riding on 15-inch wheels.
Sub-model fitment matters on the 2018 Mitsubishi Mirage G4 because the tire size is not the same across the entire range. The key step is identifying whether the car is an ES or an SE, then confirming whether it is on 14-inch or 15-inch wheels before selecting a tire.

2018 Mitsubishi Mirage G4 ES
The 2018 Mitsubishi Mirage G4 ES can use either of the two primary radial sizes, so this trim requires closer wheel confirmation than the rest of the lineup. Tire selection starts with verifying whether the car is equipped with 14-inch or 15-inch rims, then choosing within that exact fitment.
The 2018 Mitsubishi Mirage G4 SE uses the 175/55R15 radial fitment, which keeps sizing more straightforward than the ES. The main job here is confirming that the car still has its 15-inch wheel setup and has not been changed to a different wheel-and-tire combination.
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 2018 Mitsubishi Mirage G4 usually come down to correct tire size by trim, 14-inch versus 15-inch wheel fitment, and what to check before replacing tires on a compact sedan that may have seen wheel or suspension changes.
Tire Size & Fitment
What tire size fits a 2018 Mitsubishi Mirage G4?
The 2018 Mitsubishi Mirage G4 uses two primary radial tire sizes: 165/65R14 and 175/55R15. The exact size depends on the sub-model and wheel setup, with the ES using either size and the SE using 175/55R15.
Getting the right tire starts with confirming the exact trim and the actual wheel diameter on the car. An ES should not be assumed to use one size or the other without checking, because the 14-inch and 15-inch fitments are different and each requires its own matching tire.
What size rim does a 2018 Mitsubishi Mirage G4 use?
A 2018 Mitsubishi Mirage G4 uses either a 14-inch or 15-inch rim, depending on which tire size is on the car. The 165/65R14 fitment uses a 14-inch rim, while the 175/55R15 fitment uses a 15-inch rim.
Wheel diameter should be confirmed before replacing tires, especially on an ES, because both fitments appear within that trim. Looking at the current tire sidewall and verifying the wheel itself helps prevent ordering a tire that matches the model name but not the actual wheel package on the vehicle.
Do all 2018 Mitsubishi Mirage G4 sub-models use the same tire size?
No. The 2018 Mitsubishi Mirage G4 sub-models do not all use the same tire size. The ES can be equipped with either 165/65R14 or 175/55R15, while the SE uses 175/55R15.
That difference matters because the two sizes are built for different wheel diameters. A buyer shopping by year, make, and model alone can miss the trim-level split, so the safer approach is to confirm sub-model first, then verify the tire size already mounted on the car before selecting replacements.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Mitsubishi Mirage G4?
Start with the correct primary size for the car: 165/65R14 or 175/55R15. On a 2018 Mitsubishi Mirage G4, the right choice depends on sub-model and wheel diameter, so the first consideration is matching the replacement tire to the actual setup on the vehicle.
After size is confirmed, compare the tire's intended use with how the car is driven. A daily commuter may need different priorities than a lightly used city car, and it is also smart to check load capacity, overall tire condition on the remaining set, and whether the car has stock wheels or an altered setup.
How do I choose between the available 2018 Mitsubishi Mirage G4 tire sizes?
The two sizes are not interchangeable choices for personal preference alone. The 2018 Mitsubishi Mirage G4 uses 165/65R14 with a 14-inch wheel or 175/55R15 with a 15-inch wheel, so the correct size is determined by the wheel diameter and trim configuration already on the car.
An ES owner should verify the current wheel package before buying tires, since that trim can appear with either fitment. An SE owner will usually be focused on the 175/55R15 size, but it is still worth checking the car itself in case wheels were changed by a previous owner.
How do I choose between the available tires for a 2018 Mitsubishi Mirage G4?
Once the size is confirmed, compare tires within that exact fitment rather than cross-shopping between the 14-inch and 15-inch sizes. The 2018 Mitsubishi Mirage G4 is sensitive to wheel-and-tire sizing because of its compact dimensions, so staying within the correct size category is the starting point.
From there, focus on practical factors such as the car's use, expected ride characteristics, and compatibility with the existing wheels. It also helps to inspect the other tires on the car and decide whether a matched set makes more sense than replacing a single tire on a vehicle used for regular commuting.
Restoration & Appearance
Does correct tire fitment matter for a 2018 Mitsubishi Mirage G4 restoration?
Yes. Even on a newer compact sedan like the 2018 Mitsubishi Mirage G4, correct tire fitment matters if the goal is to keep the car visually and mechanically close to its intended configuration. That means using the proper 165/65R14 or 175/55R15 size for the exact trim and wheel package.
Appearance on a restoration-minded Mirage G4 is influenced by the relationship between tire size, wheel diameter, and overall stance. A mismatched size can change the look of the car and complicate clearance, so preserving the proper wheel-and-tire pairing is usually the cleanest starting point for a stock-style presentation.
Which tire should I choose for a period-style 2018 Mitsubishi Mirage G4?
A period-style approach for a 2018 Mitsubishi Mirage G4 starts with using the tire size that matches the car's original wheel diameter and trim configuration. That means 165/65R14 for the 14-inch setup or 175/55R15 for the 15-inch setup, depending on the exact car.
Keeping the correct size preserves the proportions the Mirage G4 was designed around, which matters more than chasing an oversized or undersized look. If originality is important, compare the current wheels and tires carefully and avoid assuming every ES or every used Mirage G4 still carries its original setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Mitsubishi Mirage G4?
Yes. Modifications can affect tire fitment on a 2018 Mitsubishi Mirage G4, especially if the car has aftermarket wheels, altered suspension height, or changes that move the wheel inward or outward from its original position. Those changes can influence which tire size works safely on the car.
A Mirage G4 that started with one of the stock fitments may no longer have the same clearance around the fenders, struts, or steering components. Checking wheel diameter, width, and tire-to-body clearance before replacement is a smart step whenever the car has been customized or its current setup is uncertain.
What should I inspect before driving a 2018 Mitsubishi Mirage G4 on new tires?
Before road use, inspect air pressure, wheel condition, lug nut torque, and the tire sidewalls and tread for any visible damage from handling or installation. On a 2018 Mitsubishi Mirage G4, it is also important to confirm that all four tires match the intended size and wheel diameter for the car.
A short visual and driving check can catch issues early. Look for rubbing at full steering lock, listen for unusual contact noises, and recheck pressure after the first drives, especially if the car was recently purchased, had old tires replaced, or may have a non-stock wheel setup.
How often should tires on a 2018 Mitsubishi Mirage G4 be inspected?
Tires on a 2018 Mitsubishi Mirage G4 should be inspected regularly rather than only when wear becomes obvious. A quick check for pressure loss, uneven tread wear, cuts, cracking, or sidewall damage helps catch problems early, particularly on a small sedan where tire condition strongly affects day-to-day drivability.
Frequent inspection is even more useful if the car sits for long periods, is driven on rough city streets, or has had alignment or suspension work. Any sign of unusual wear should prompt a closer look at the wheels and front-end setup, because the correct tire size alone does not prevent fitment-related issues.
