The 2020 Mitsubishi lineup focused on simple, efficient transportation, and the Mirage family carried that mission with subcompact dimensions, light weight, and city-friendly manners. In sedan and hatchback form, 2020 Mitsubishi appealed to buyers who valued economy and easy ownership more than outright size or power. Across the two-model range, both the Mirage and Mirage G4 use the same two radial tire sizes, so the real choice is less about model-specific fitment and more about confirming which wheel diameter your car has. Before choosing a tire, verify whether your 2020 Mitsubishi wears 14-inch or 15-inch wheels, then match the correct size to that wheel.
Which Tire Size Is Right for Your 2020 Mitsubishi
Two tire sizes are used across 2020 Mitsubishi Mirage-family vehicles, and both sizes are shared by both models rather than split by model. Because these are radial sizes on different wheel diameters, the main decision is confirming whether your car has 14-inch or 15-inch wheels before narrowing down the exact tire. Understanding that distinction first saves time and helps ensure the right match.
The 165/65R14 is a metric radial size with a 165-millimeter section width, a 65-series aspect ratio, and a fitment for 14-inch wheels. It is a radial construction used by both 2020 Mitsubishi Mirage models and both 2020 Mitsubishi Mirage G4 models. This size suits owners whose car is already equipped with 14-inch wheels and who want to stay with the factory wheel diameter rather than change to a different wheel size.
The 175/55R15 is a metric radial size with a 175-millimeter section width, a 55-series aspect ratio, and a fitment for 15-inch wheels. It is also shared across both 2020 Mitsubishi Mirage and 2020 Mitsubishi Mirage G4 models, but it mounts on a different wheel diameter than the 14-inch option. This size is the correct choice for cars equipped with 15-inch wheels and keeps the tire matched to that original wheel package.
Two 2020 Mitsubishi models are covered here: the Mirage hatchback and the Mirage G4 sedan. Both use the same two tire sizes, so fitment does not change by model name alone; the practical difference is identifying whether your specific car has the 14-inch or 15-inch wheel package. Select your model below for model-specific fitment history and products.
2020 Mitsubishi Mirage
The 2020 Mitsubishi Mirage is the hatchback member of the Mirage family, aimed at drivers who want compact size, easy maneuverability, and low running costs. Its tires mount on either 14-inch or 15-inch wheels depending on the wheel package fitted to the car, so wheel diameter is the key detail to confirm before choosing a replacement tire.
The 2020 Mitsubishi Mirage G4 is the sedan version of the Mirage, offering the same basic economy-car mission with a separate trunk and a slightly different body style. Like the hatchback, it uses either 14-inch or 15-inch wheel fitments, so the wheel on the car matters more than the body style when selecting tires.
These FAQs cover the two wheel-and-tire combinations used across the 2020 Mitsubishi Mirage range, including what the size codes mean, whether both models share the same fitment logic, and what to check before replacement or longer-term collector-style storage.
Size Basics & Fitment
What tire sizes fit 2020 Mitsubishi vehicles?
2020 Mitsubishi Mirage and 2020 Mitsubishi Mirage G4 vehicles use two tire sizes: 165/65R14 and 175/55R15. Both sizes are shared across both models, so there is no separate Mirage-only or Mirage G4-only size in this year range. The difference is wheel diameter, with one size fitting 14-inch wheels and the other fitting 15-inch wheels.
That means a 2020 Mitsubishi owner should identify the wheel diameter on the car before choosing a replacement tire. The model name alone is not enough, because either body style can use either size. Checking the sidewall on the existing tire or the wheel-and-tire label on the vehicle is the quickest way to confirm which of the two sizes belongs on your car.
What does 165/65R14 mean on a 2020 Mitsubishi tire?
On a 2020 Mitsubishi, 165/65R14 is a metric radial tire size. The 165 is the section width in millimeters, 65 is the aspect ratio, meaning the sidewall height is 65 percent of the section width, R identifies radial construction, and 14 is the wheel diameter in inches. It is one of the two factory fitment patterns used on Mirage and Mirage G4 models.
Understanding that code helps prevent mix-ups with the 15-inch option. A 165/65R14 tire cannot simply be substituted onto a 15-inch wheel, even though both sizes belong to the same year and make. If your car wears 14-inch wheels, this is the size family you should be researching first when comparing replacements.
What does 175/55R15 mean on a 2020 Mitsubishi tire?
On a 2020 Mitsubishi, 175/55R15 is a metric radial tire size with a 175-millimeter section width, a 55-series aspect ratio, radial construction, and a 15-inch wheel fitment. It is the second of the two tire sizes used across 2020 Mirage and Mirage G4 models. The shorter sidewall is part of what distinguishes it from the 14-inch fitment.
This size matters because it confirms a different wheel package, not just a slightly different tire. If your 2020 Mitsubishi has 15-inch wheels, you should stay within the 175/55R15 fitment unless you are making a broader wheel-and-tire change and have verified all related clearances. Matching the tire to the correct wheel diameter is the first fitment step.
Do all 2020 Mitsubishi models use the same tire size?
Yes and no: both 2020 Mitsubishi Mirage models use the same two approved size families, but not every individual car wears the same one. Mirage and Mirage G4 can both be found with 165/65R14 or 175/55R15, depending on the wheel package installed. The size choice is shared across the range rather than separated by body style.
For a buyer or owner, that means the model name narrows the search, but the final answer comes from the actual wheel diameter on the car. A hatchback is not automatically a 14-inch fitment, and a sedan is not automatically a 15-inch fitment. Confirm the existing sidewall marking or vehicle placard before committing to a tire.
Buying the Right Tire
Should I choose the 165/65R14 or the 175/55R15 for my 2020 Mitsubishi?
A 2020 Mitsubishi should use the size that matches its wheel diameter: 165/65R14 for 14-inch wheels or 175/55R15 for 15-inch wheels. Both are radial sizes used across Mirage and Mirage G4 models, so this is not a bias-ply-versus-radial decision. It is a wheel-package decision tied directly to the wheel already on the car.
If you are replacing tires on the original wheels, use the same size that is already fitted unless you have confirmed a different wheel setup. If you are looking at a used 2020 Mitsubishi and are unsure what it has, the existing sidewall code will answer the question immediately. Choosing by wheel diameter first avoids unnecessary fitment confusion.
What brands make tires for 2020 Mitsubishi vehicles?
The two 2020 Mitsubishi sizes here are both modern metric radial fitments, which generally place them in the mainstream passenger-car tire category rather than a niche vintage-only category. Brand choice depends on the exact size you need, whether that is 165/65R14 or 175/55R15, and the specific product lines available in that size. The important first step is locking in the correct size before comparing brands.
Once the wheel diameter is confirmed, you can compare replacement tires on construction details, intended use, and overall road manners within that exact size. That approach is more useful than comparing brands across both sizes at once, because the real fitment boundary on a 2020 Mitsubishi is the 14-inch versus 15-inch wheel package.
What sidewall styles are available for 2020 Mitsubishi tires?
A 2020 Mitsubishi uses modern metric radial tire sizing, so the sidewall look is generally contemporary rather than styled around older wide-white or vintage blackwall authenticity themes. Mirage and Mirage G4 buyers are usually choosing within standard modern passenger-tire sidewall treatments that prioritize clean, current appearance. The sidewall style question is therefore less about historical correctness and more about the visual character of the specific tire line.
That matters if you want the car to look as close as possible to its original late-model economy-car presentation. Staying with a normal modern radial sidewall keeps the appearance in step with the era of the vehicle. Once the correct 14-inch or 15-inch size is confirmed, sidewall appearance becomes a secondary choice rather than the main fitment question.
Fitting & Setup
Do 2020 Mitsubishi tires require inner tubes?
2020 Mitsubishi Mirage-family tires are modern radial fitments, and these size conventions are normally associated with tubeless passenger-car use on appropriate modern rims. The key point is that 165/65R14 and 175/55R15 are not vintage tube-type sizing formats from an earlier era. Tube use should match the tire and wheel design rather than be assumed simply from the vehicle name.
If your 2020 Mitsubishi still has its original-style modern wheels, a tubeless setup is the normal expectation. If the car has replacement wheels, repaired rims, or an unusual aftermarket setup, confirm the wheel condition and the tire’s own sidewall marking before installation. That is especially important if you are dealing with a used car whose wheel history is not fully clear.
Can the original 2020 Mitsubishi wheels be used with both tire sizes?
Original 2020 Mitsubishi wheels can be used with both tire sizes only in the sense that the Mirage range came with both 14-inch and 15-inch wheel packages. A 165/65R14 fits a 14-inch wheel, while a 175/55R15 fits a 15-inch wheel. The tire does not interchange across those wheel diameters without changing the wheel itself.
That means a tire-only replacement should stay with the size already matched to the wheel on the car. If you are considering moving from one size to the other, treat it as a wheel-and-tire package change rather than a simple substitute. Confirm wheel diameter first, then evaluate the broader effects of any wheel change on your specific Mirage or Mirage G4.
Maintenance, Storage & Longevity
How should I store a 2020 Mitsubishi when the tires are fitted?
A 2020 Mitsubishi should be stored on clean, properly inflated tires in a cool, dry area away from direct sunlight, electric motors, welders, furnaces, and other ozone-producing sources. Even modern radial tires age faster when exposed to heat, UV, and long periods of underinflation. Moving the car slightly from time to time can also help reduce prolonged stress on one section of the casing.
If the car will sit for a season or longer, keep the tires off damp soil or bare concrete and make sure the storage area stays reasonably stable in temperature. Owners who store the car for extended periods sometimes use stands to reduce load, but that should be done carefully and with proper support points. The goal is preserving the tire structure as much as preserving the tread.
How long do tires on a 2020 Mitsubishi typically last?
Tires on a 2020 Mitsubishi should be judged by age and condition as much as tread depth. A sensible rule is to evaluate them closely once they reach the five- to seven-year range, and to treat around ten years from the date of manufacture as a serious replacement consideration even if they still look usable. The DOT date code on the sidewall identifies the tire’s age.
That matters because many Mirage and Mirage G4 cars are low-mileage vehicles, and low mileage can hide age-related hardening or cracking. A tire that looks only lightly worn may still be well past its best service life. Regular age checks help you avoid relying on tread depth alone when deciding whether a set is still suitable for use.
How often should tires on a 2020 Mitsubishi be inspected?
Tires on a 2020 Mitsubishi should be inspected before every drive, with a more thorough check before any longer trip. Look for sidewall cracking, cuts, bulges, uneven tread wear, punctures, and any sign that a tire is losing pressure. On a light subcompact like the Mirage, even a small pressure change can noticeably affect ride and handling behavior.
A longer outing deserves an extra walkaround that includes the spare, valve stems, and overall tread condition across all four corners. If the car has been parked for a while, check for flat spotting or pressure loss before heading onto faster roads. Routine inspection is one of the simplest ways to catch age or impact damage before it becomes a roadside problem.
Safety & Road Use
Are 2020 Mitsubishi tires safe for highway driving?
A properly selected and properly maintained radial tire in the correct 2020 Mitsubishi size is suitable for normal highway driving when it is in good condition and inflated correctly. Both 165/65R14 and 175/55R15 are modern radial fitments rather than antique or bias-ply sizes, so the basic design is aligned with contemporary road use. Tire safety still depends heavily on age, condition, inflation, and the overall mechanical state of the car.
On a 2020 Mitsubishi Mirage or Mirage G4, highway confidence is often influenced as much by alignment, braking condition, and suspension health as by the tire itself. A fresh tire cannot compensate for neglected chassis or brake components. Before regular higher-speed use, make sure the whole car is roadworthy and that all four tires match the correct size for the wheels installed.
What inflation pressure should I use for 2020 Mitsubishi tires?
A 2020 Mitsubishi should use the factory inflation pressure specified for its exact model and wheel-and-tire package, not a guessed number taken from another size. Because both 165/65R14 and 175/55R15 were used across the Mirage family, pressure guidance should come from the vehicle placard or owner’s manual for the car in front of you. The pressure printed on the tire itself is not the default running recommendation for the vehicle.
That distinction matters because the right operating pressure is set by the car maker around weight distribution, ride, and handling, while the number on the tire reflects the tire’s maximum rated condition. Start with the vehicle recommendation, then maintain it consistently with a good gauge. If the car has a non-original wheel-and-tire package, confirm the correct operating pressure with the tire manufacturer.
What should I check before taking a 2020 Mitsubishi on a longer drive?
Before a longer drive in a 2020 Mitsubishi, inspect all four tires for cracks, punctures, bulges, uneven wear, and proper cold inflation pressure. Confirm that the car has four matching correct-size tires for the wheels installed, whether that is 165/65R14 or 175/55R15, and check the spare as well. A quick look at valve stems and tread depth is part of the same routine.
Tires are only one part of the preparation, so pair that inspection with a broader check of brakes, fluids, battery condition, and lights. Even though a 2020 Mirage is much newer than a vintage collector car, long periods of light use can still create age-related issues. A few minutes of pre-drive inspection can prevent a simple tire or maintenance problem from interrupting the trip.
