The 2019 Mitsubishi Trucks Outlander PHEV blends crossover utility with plug-in hybrid capability, making it a distinct choice for drivers who want everyday practicality without giving up electric-assisted driving. Its road manners, weight distribution, and all-weather usability make tire condition and fitment especially important. For this model, the primary fitment is a 225/55R18 radial on an 18-inch rim, and that same size carries across both GT and SEL sub-models. That keeps the size question simple, while leaving room to focus on choosing the right radial tire for ride quality, seasonal use, and overall driving confidence. Before replacing tires, it is worth confirming the actual wheel setup and inspecting the vehicle for any prior modifications.
Which Tire Size Is Right for The 2019 Mitsubishi Trucks Outlander PHEV
The 2019 Mitsubishi Trucks Outlander PHEV uses one primary tire size: 225/55R18 radial on an 18-inch rim. That fitment is shared across the covered GT and SEL sub-models, so the main decision is not which size fits, but which tire within that size best matches the vehicle's road use, wheel setup, and overall condition.
225/55R18 is a modern metric radial size in which 225 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 18 is the wheel diameter in inches. On the 2019 Mitsubishi Trucks Outlander PHEV, this sizing reflects a contemporary crossover fitment with a balance of sidewall height and 18-inch wheel diameter. Because both GT and SEL use this same size, selection centers on choosing a tire suited to the vehicle's intended driving conditions. It is still smart to confirm the actual wheel dimensions and check for any aftermarket changes before replacement.
Tire fitment is straightforward across the covered 2019 Mitsubishi Trucks Outlander PHEV sub-models because both use the same primary tire size. Checking the exact sub-model still helps confirm that the vehicle remains on its proper 18-inch wheel setup before a new set of tires is chosen.

Frequently Asked Questions
These FAQs focus on the 225/55R18 fitment used on the 2019 Mitsubishi Trucks Outlander PHEV, along with rim sizing, tire selection, maintenance, and the checks that matter before putting a hybrid crossover back on the road.
Tire Size & Fitment
What tire size fits a 2019 Mitsubishi Trucks Outlander PHEV?
The 2019 Mitsubishi Trucks Outlander PHEV uses a 225/55R18 radial tire. That size is the primary fitment for the covered model, and it is used on an 18-inch wheel. Both the GT and SEL sub-models use this same tire size, which keeps fitment straightforward for most replacement decisions.
Even with a single shared size, it is still worth checking the actual wheels on the vehicle before buying tires. A previous owner may have changed wheel width, offset, or overall wheel diameter, and those changes can affect fitment, clearance, and the way a replacement tire sits on the vehicle.
What size rim does a 2019 Mitsubishi Trucks Outlander PHEV use?
The primary tire fitment for the 2019 Mitsubishi Trucks Outlander PHEV is built around an 18-inch rim. The 225/55R18 size ends with 18, which identifies the wheel diameter in inches. That 18-inch diameter applies across the covered sub-models using this factory-style tire size.
Wheel diameter is only one part of the fitment picture, so the next check is wheel width and overall wheel setup. A tire can share the correct 18-inch diameter but still be mismatched to the wheel or vehicle if offset, width, suspension height, or brake clearance has been changed from stock-style configuration.
Do all 2019 Mitsubishi Trucks Outlander PHEV sub-models use the same tire size?
Yes. The covered 2019 Mitsubishi Trucks Outlander PHEV sub-models use the same 225/55R18 radial tire size. Both the GT and SEL are associated with that fitment, so there is no split in primary tire size between those two versions of the vehicle.
That consistency simplifies replacement, but it does not remove the need to inspect the vehicle itself. Tires should still be matched to the actual wheels currently installed, and any lowering, lift changes, aftermarket wheels, or suspension repairs should be considered before assuming the same size will suit every individual Outlander PHEV on the road.
Choosing the Right Tire
What should I consider when choosing a 225/55R18 tire for a 2019 Mitsubishi Trucks Outlander PHEV?
Start with the correct size and construction: 225/55R18 radial on an 18-inch rim. From there, the important considerations are the vehicle's real-world use, such as commuting, wet-weather driving, highway miles, or occasional long-distance travel. Ride quality, tread design, and how the tire complements the crossover's plug-in hybrid character all matter.
A smart comparison also includes the actual wheel dimensions and the condition of the suspension and steering components. Uneven wear, alignment issues, or non-stock wheels can change how a new tire performs, so choosing the right 225/55R18 means looking beyond the sidewall and considering the complete vehicle setup.
How do I choose between the available 225/55R18 tires for a 2019 Mitsubishi Trucks Outlander PHEV?
The best approach is to compare tires within the correct 225/55R18 size based on how the Outlander PHEV is driven. Some owners prioritize quiet highway use and everyday comfort, while others put more emphasis on wet-road confidence or year-round practicality. Staying with the proper size keeps the fitment baseline correct.
It also helps to look at the vehicle as it sits today rather than assuming every example remains unchanged. Wheel substitutions, prior suspension work, and uneven tire wear patterns can all affect what makes sense as a replacement, especially on a heavier electrified crossover that depends on stable, predictable tire behavior.
What rim-fitment details should I compare when choosing tires for a 2019 Mitsubishi Trucks Outlander PHEV?
The first rim-fitment detail is wheel diameter, which is 18 inches for the 2019 Mitsubishi Trucks Outlander PHEV's 225/55R18 size. After that, wheel width and overall wheel design should be checked to be sure the selected tire matches the actual hardware on the vehicle rather than only the size molded into the old tire.
Offset and brake clearance can matter just as much as diameter, especially if aftermarket wheels have been installed. Looking at the complete wheel and tire package helps prevent issues with sidewall shape, clearance at full lock, or a stance that differs from what the vehicle was designed to carry.
Restoration & Appearance
Does correct tire fitment matter for a 2019 Mitsubishi Trucks Outlander PHEV restoration?
Yes. Even on a newer collector-leaning or preservation-minded vehicle, correct tire fitment affects both appearance and the way the vehicle sits and drives. For the 2019 Mitsubishi Trucks Outlander PHEV, the baseline fitment is 225/55R18 radial, so staying with the proper size helps preserve the intended relationship between tire, wheel, and body.
Appearance-minded owners should still verify the actual wheel package before replacing tires, especially if the vehicle has changed hands. A correct-looking stance can be thrown off by non-stock wheel widths or offsets, and careful fitment choices help maintain a clean, appropriate presentation without assuming every surviving example remains unchanged.
How does tire construction affect the appearance of a restored 2019 Mitsubishi Trucks Outlander PHEV?
The 2019 Mitsubishi Trucks Outlander PHEV uses a radial tire, so retaining radial construction keeps the vehicle aligned with its intended modern crossover look and driving character. Unlike many vintage applications, the appearance question here is less about bias-ply versus radial styling and more about maintaining the proper 225/55R18 proportions on the correct 18-inch wheels.
A restored or carefully preserved example can still look noticeably different if the tire profile or wheel package has been altered. Keeping the correct size and checking overall stance, wheel fitment, and clearance helps the vehicle present as it should, without introducing a mismatched tire shape or an overdone wheel-and-tire combination.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Mitsubishi Trucks Outlander PHEV?
Yes. The 2019 Mitsubishi Trucks Outlander PHEV uses 225/55R18 tires, but modifications can change how that size fits in practice. Aftermarket wheels, altered offsets, suspension changes, or brake upgrades can all affect clearance, steering movement, and the way the tire sits within the wheel opening.
That is why the vehicle should be checked as it currently stands rather than by model name alone. Looking at wheel width, ride height, and clearance at full steering lock helps catch issues before replacement tires are installed, especially when the crossover no longer carries its original-style wheel and suspension setup.
What should I inspect before driving a 2019 Mitsubishi Trucks Outlander PHEV on new tires?
Before putting a 2019 Mitsubishi Trucks Outlander PHEV back into regular road use on new tires, inspect tire pressure, wheel fastener torque, and the general condition of the wheels themselves. It also makes sense to check alignment-related wear patterns, suspension condition, and whether the old tires showed signs of rubbing or uneven contact.
A careful road-use check should also include sidewall clearance, steering response, and any vibration that appears once the vehicle is moving. Hybrid crossovers place steady demands on tires in everyday use, so confirming that the new 225/55R18 set is seated, balanced, and running properly helps avoid preventable issues early.
How often should tires on a 2019 Mitsubishi Trucks Outlander PHEV be inspected?
Tires on a 2019 Mitsubishi Trucks Outlander PHEV should be inspected regularly rather than only when visible wear becomes obvious. Pressure loss, uneven tread wear, cuts, bulges, and sidewall damage can develop gradually, and a quick visual check paired with routine pressure checks helps catch problems before they become more serious.
Inspection matters even more if the vehicle is driven infrequently or stored for stretches of time. A crossover that spends long periods parked can still develop age-related issues, so keeping an eye on cracking, flat spotting, and overall condition is just as important as measuring tread depth on a frequently driven vehicle.
