The 2023 Toyota Mirai is a modern hydrogen fuel-cell sedan with a distinctly upscale, long-wheelbase character that separates it from ordinary commuter cars. Its smooth, quiet road manners put extra attention on tire choice, because wheel size and profile have a visible effect on both stance and everyday drivability. For this model year, the Mirai uses radial tires in two sizes: 235/55R19 and 245/45R20, with fitment varying by sub-model and wheel setup. That means the real decision is not just picking a tire, but confirming whether your car is on 19-inch or 20-inch wheels and then choosing the right series, brand, and sidewall style for how the car is driven and presented.
Which Tire Size Is Right for The 2023 Toyota Mirai
The 2023 Toyota Mirai uses two primary tire sizes, and the right one depends first on the exact sub-model and wheel diameter. Both fitments are radial, but one uses a 19-inch rim and the other uses a 20-inch rim, so confirming the actual wheel on the car is the first step before comparing tire series, sidewall style, or brand options.
In 235/55R19, the 235 identifies the tire's nominal section width in millimeters, 55 is the aspect ratio, R denotes radial construction, and 19 is the wheel diameter in inches. This is a modern radial fitment that suits the Mirai's contemporary sedan layout and is used on the 19-inch wheel setup. Because this size is tied to the XLE and also appears on Limited models, the key question is usually confirmation of the wheel already on the car. Once that is settled, selection comes down to matching the tire to the vehicle's actual setup and intended use.
In 245/45R20, the 245 is the nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 20 identifies the rim diameter in inches. This size is used on the Mirai's 20-inch wheel application and brings a lower-profile fitment than the 19-inch size. Available choices in this size include BFGoodrich, Nitto, and Pro-Trac products, with sidewall treatments such as Blackwall, Redline, and RWL across several tire series. It is the size to evaluate when a Limited model is equipped with 20-inch wheels or when the car has that wheel diameter already installed.
Tire fitment on the 2023 Toyota Mirai is not the same across every covered sub-model. Checking whether the car is an XLE or a Limited matters, and on the Limited it is just as important to confirm whether the vehicle is riding on 19-inch or 20-inch wheels.

2023 Toyota Mirai Limited
The 2023 Toyota Mirai Limited can use either of the Mirai's two radial tire sizes, so this trim requires extra attention before any purchase decision is made. Wheel diameter is the key checkpoint here, because the tire choice depends on whether the car is equipped with 19-inch or 20-inch wheels.
The 2023 Toyota Mirai XLE uses the 235/55R19 radial size, which makes fitment more straightforward than on the Limited. With the size question narrowed down, the decision becomes making sure the tire matches the 19-inch wheel setup and the way the car is used on the road.
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.
Best 2023 Toyota Mirai Tires for Sale
Available 245/45R20 choices for the 2023 Toyota Mirai include BFGoodrich, Nitto, and Pro-Trac offerings in several series. The main differences to compare are Blackwall, Redline, and RWL sidewall treatments along with rim-width specifications and other product-level characteristics.
The most useful tire questions for a 2023 Toyota Mirai usually come down to exact size, wheel diameter, trim-level fitment, and how to compare the available 245/45R20 tire choices. Maintenance and wheel-change checks also matter, especially on a model that can appear with either 19-inch or 20-inch wheels.
Tire Size & Fitment
What tire size fits a 2023 Toyota Mirai?
The 2023 Toyota Mirai uses two tire sizes: 235/55R19 and 245/45R20. Both are radial fitments, but they do not apply the same way across the lineup because the XLE uses 235/55R19, while the Limited can appear with either 235/55R19 or 245/45R20 depending on the wheel setup.
That makes wheel confirmation the first step before selecting a replacement tire. A 19-inch wheel requires the 235/55R19 fitment, while a 20-inch wheel requires 245/45R20. If the car has been changed from its original wheel setup, check the actual wheel diameter and width on the vehicle rather than relying only on trim name.
What size rim does a 2023 Toyota Mirai use?
The 2023 Toyota Mirai uses either a 19-inch rim or a 20-inch rim, depending on the tire size fitted to the car. The 235/55R19 size mounts on a 19-inch wheel, and the 245/45R20 size mounts on a 20-inch wheel.
Rim diameter is the most important fitment checkpoint because it determines which tire size even belongs in consideration. A tire for a 19-inch wheel cannot be used on a 20-inch wheel, and the reverse is also true. Checking the wheel itself is especially important on a Mirai Limited, since that sub-model can use either wheel diameter.
Do all 2023 Toyota Mirai sub-models use the same tire size?
No. The 2023 Toyota Mirai XLE uses 235/55R19, while the 2023 Toyota Mirai Limited can use either 235/55R19 or 245/45R20. That means sub-model name alone does not fully answer the fitment question for every Mirai on the road.
The practical takeaway is that an XLE is straightforward, but a Limited needs closer verification before ordering tires. Looking at the current wheel diameter on the car is the safest next step, especially if the vehicle was purchased used or has had wheels changed. Once the wheel size is confirmed, the tire search becomes much more focused.
Choosing the Right Tire
What should I consider when choosing a 245/45R20 tire for a 2023 Toyota Mirai?
Start with the basics: confirm that the car actually uses the 245/45R20 fitment and that the wheel is a 20-inch wheel. From there, compare tire construction, sidewall style, rim-width compatibility, weight, and any stated load information so the tire suits both the wheel and the way the Mirai is driven.
This size includes several different product personalities, so the decision is not only about matching dimensions. Some buyers will focus on a clean blackwall look, while others may prefer a redline or raised white letter presentation. It also helps to compare the actual wheel width on the car against the tire's approved rim-width range before making a final choice.
What sidewall styles are available for 2023 Toyota Mirai tires?
In the available 245/45R20 selection for the 2023 Toyota Mirai, sidewall styles include Blackwall, Redline, and RWL. Blackwall appears across several performance-oriented radial choices, while the Pro-Trac Street Pro III line adds Redline and RWL options for buyers who want a more customized visual presentation.
Sidewall style will not change the required tire size, but it can significantly change how the car looks. A Mirai with 20-inch wheels can take on a more understated or more expressive appearance depending on that choice. It is worth deciding early whether the goal is a modern, low-key look or a more distinctive enthusiast-style sidewall treatment.
What brands offer tires for the 2023 Toyota Mirai?
Available 245/45R20 tires for the 2023 Toyota Mirai come from BFGoodrich, Nitto, and Pro-Trac. Within those brands, the choices span several tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, Nitto NT555 G2, and Pro-Trac Street Pro III.
Brand is only one part of the comparison. It still makes sense to review the series character, the sidewall treatment, and the wheel-width specification so the tire aligns with the car's actual setup and the owner's preferences. On a Mirai running 20-inch wheels, appearance and wheel compatibility can matter just as much as brand familiarity.
Restoration & Appearance
Which tire should I choose for a period-style 2023 Toyota Mirai?
A period-style approach is less about restoration on a 2023 Toyota Mirai and more about preserving the car's intended modern character. The starting point is still the correct primary size for the wheel on the car, with 235/55R19 for the 19-inch setup and 245/45R20 for the 20-inch setup.
From there, appearance comes down to how subtle or expressive the finished look should be. A blackwall tire keeps the presentation closest to a contemporary luxury-sedan theme, while some 245/45R20 options add enthusiast-oriented styling cues. Keeping the correct size and wheel match matters more here than chasing a vintage look that does not suit the Mirai's design language.
Which sidewall style suits a period-style 2023 Toyota Mirai?
For a 2023 Toyota Mirai, Blackwall is the most natural sidewall choice when the goal is to maintain a clean, contemporary appearance. Redline and RWL are also available in 245/45R20, but those treatments create a more customized visual statement than a restrained modern sedan typically carries.
The best choice depends on how the car is presented rather than on fitment alone, since sidewall style does not change the required wheel diameter or tire size. Buyers who want the Mirai to retain a more original-feeling visual tone will usually lean toward Blackwall, while Redline or RWL can make sense on a car built around a more personalized appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2023 Toyota Mirai?
Yes. Wheel changes, suspension alterations, and other modifications can affect tire fitment on a 2023 Toyota Mirai even when the tire size sounds close to the original application. Changes in wheel diameter or width are especially important on this model because the Mirai already uses both 19-inch and 20-inch fitments depending on configuration.
A modified car should be checked for actual wheel size, wheel width, and visible clearance around the fenders and steering components before choosing a tire. Even within the correct basic size, the vehicle's current setup matters. That is particularly relevant on a used Mirai, where the wheels on the car may not match the trim's original configuration.
What should I inspect before driving a 2023 Toyota Mirai on new tires?
Before driving a 2023 Toyota Mirai on new tires, inspect the wheels for damage, confirm the correct tire size for the wheel diameter, and make sure the tires are inflated properly for the vehicle's requirements. It is also wise to check for any visible rubbing risk around the wheel openings and steering travel.
A short initial road test can reveal vibration, pull, or interference that is easier to correct early. After that first drive, recheck pressure and look over the sidewalls and tread for any unusual signs. On a Mirai Limited, this process is especially important because a mistake between the 19-inch and 20-inch fitments starts with wheel confirmation.
How often should tires on a 2023 Toyota Mirai be inspected?
Tires on a 2023 Toyota Mirai should be inspected regularly, not just when they look low or begin to wear. A visual check for uneven tread wear, cuts, bulges, punctures, and sidewall damage is a good habit, and air pressure should be monitored consistently because correct inflation affects both tire life and road manners.
Inspection becomes even more important if the car is driven infrequently or sits for extended periods. Low-use vehicles can still develop age-related issues or slow air loss that are easy to miss. Taking a close look before longer trips and after seasonal temperature changes helps catch problems before they turn into fitment, ride, or safety concerns.
