The 2020 Toyota Mirai stands apart from most modern sedans because its appeal is tied as much to advanced engineering as to daily road use. As an early hydrogen fuel-cell production vehicle, it attracts owners who value originality, technical character, and careful maintenance rather than casual parts substitution. For this exact model, the primary tire fitment is a 215/55R17 radial on a 17-inch rim, which keeps the selection process focused on the correct metric size rather than sorting through multiple factory fitments. Available choices stay within that format, with BFGoodrich options in Blackwall performance-oriented radial series. The real decision is matching the proper 17-inch fitment to your driving needs, wheel setup, and overall vehicle condition.
Which Tire Size Is Right for The 2020 Toyota Mirai
The 2020 Toyota Mirai uses one primary tire size: 215/55R17, a radial tire for a 17-inch rim. The Mirai Base uses that same size, so the main choice is not between multiple fitments, but between available tires within the correct size, series, and intended road-use character.
A 215/55R17 size uses a 215-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2020 Toyota Mirai, this modern metric radial format matches the vehicle’s primary fitment and keeps the focus on maintaining the intended wheel diameter and overall tire profile. Available options in this size include BFGoodrich Blackwall radials from the g-Force Comp 2 AS and g-Force Phenom T/A series. This size is the right starting point when the goal is to preserve proper fitment while comparing tire character, rim-width compatibility, and overall suitability for the car’s current setup.
Tire fitment is straightforward for the covered 2020 Toyota Mirai sub-models. The shared sizing means the important checks are confirming the 17-inch wheel setup and choosing the right radial tire within the correct 215/55R17 format.

Tire Size & Fitment
What tire size fits a 2020 Toyota Mirai?
The 2020 Toyota Mirai uses a 215/55R17 radial tire. That size is the primary fitment for this model and is also used on the Mirai Base, which keeps selection fairly simple compared with vehicles that split fitment by trim level or wheel package.
The practical step is confirming that the car still has the correct 17-inch wheel setup and has not been changed to an aftermarket wheel with a different width or offset. Once the wheel is verified, the decision shifts to choosing among available 215/55R17 radial tires based on tire series, load specification, and intended use.
What size rim does a 2020 Toyota Mirai use?
The primary tire fitment for the 2020 Toyota Mirai is built around a 17-inch rim. The 215/55R17 size itself confirms that wheel diameter, and the available tires in this application are also designed for a 17-inch wheel.
Wheel diameter is only part of the fitment picture, so it is still worth checking actual wheel width before selecting a tire. A car that has been fitted with non-original wheels can still be 17-inch in diameter but differ in width or offset, which can affect tire compatibility and clearance.
Does the 2020 Toyota Mirai Base use the same tire size?
Yes. The 2020 Toyota Mirai Base uses the same 215/55R17 radial tire size as the model core. That shared fitment means buyers do not need to sort between multiple primary sizes when selecting tires for the covered Mirai configuration.
Even with a shared size, it still helps to confirm the actual wheel on the car before purchase, especially if the vehicle has changed hands or received aftermarket parts. Once that is settled, the focus becomes comparing available tires in the correct size rather than trying to decode trim-specific fitment differences.
Choosing the Right Tire
What should I consider when choosing a 215/55R17 tire for a 2020 Toyota Mirai?
Start with the correct size, construction, and wheel diameter: 215/55R17 radial on a 17-inch rim. From there, compare the available tire series, sidewall style, rim-width compatibility, and load specification to make sure the tire suits both the wheel and the way the car is actually used.
A Mirai that remains close to stock may simply need the right modern metric radial in the proper fitment, while a car with wheel changes needs closer verification. Looking at the series name alone is not enough, so compare the full product details before choosing between the available BFGoodrich options.
What sidewall styles are available for 2020 Toyota Mirai tires?
The available 215/55R17 tires for the 2020 Toyota Mirai use a Blackwall sidewall style. That gives the car a clean modern appearance and keeps the choice focused more on tire series and specifications than on contrasting visual treatments such as whitewalls or raised white letters.
Because the sidewall presentation does not vary here, appearance decisions are fairly straightforward. The more meaningful comparison is whether one Blackwall radial better matches the car’s current wheel width, load needs, and driving pattern, especially if the vehicle is used regularly rather than stored for occasional specialty use.
What tire series are available for the 2020 Toyota Mirai?
The available 215/55R17 options for the 2020 Toyota Mirai include BFGoodrich tires from the g-Force Comp 2 AS and g-Force Phenom T/A series. Both are radial Blackwall choices in the correct 17-inch fitment, so the difference is not about changing size but about selecting between available series within it.
Series names help separate the products, but the smarter comparison also includes rim-width specification, load figure where stated, and the condition of the wheels already on the car. Matching the right series to the Mirai starts with correct fitment and then narrows to the tire characteristics that matter most for your intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Toyota Mirai?
A period-style approach for a 2020 Toyota Mirai still begins with the correct 215/55R17 radial size and 17-inch wheel diameter. Since the available options stay within a modern Blackwall radial presentation, the closest period-appropriate look comes from preserving the proper overall fitment rather than chasing vintage-style sidewall treatments.
This is a newer specialty vehicle, so authenticity usually means staying close to the intended tire format and avoiding unnecessary size changes. Owners pursuing a highly original appearance should compare the current wheel-and-tire setup against vehicle-specific historical references before making cosmetic changes that alter the car’s visual balance.
Does correct tire fitment matter for a 2020 Toyota Mirai restoration?
Yes, correct tire fitment matters because the 2020 Toyota Mirai is a distinctive modern specialty vehicle whose appearance depends on maintaining the proper 215/55R17 proportions on a 17-inch rim. Even small departures in size or profile can change the car’s stance and shift it away from a restoration-oriented presentation.
Fitment also affects more than appearance, since wheel width and clearance still need to work together properly. A restoration-minded owner is usually best served by confirming the actual wheels on the car, keeping the radial construction consistent with the primary fitment, and avoiding substitution based only on similar-looking numbers.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Toyota Mirai?
Yes. A 2020 Toyota Mirai may use the same 215/55R17 primary size across the covered fitment, but aftermarket wheels, altered offsets, suspension changes, or ride-height modifications can all affect whether the selected tire remains appropriate for the car’s actual setup.
The most useful checks are wheel diameter, wheel width, and physical clearance at the fenders and steering components. Even when the tire size stays the same on paper, a modified car can behave differently from a stock one, so it is worth verifying the complete wheel-and-tire package before road use.
What should I inspect before driving a 2020 Toyota Mirai on new tires?
Before driving a 2020 Toyota Mirai on new tires, inspect the wheels for damage, confirm that the 17-inch rims are the correct width for the chosen 215/55R17 tire, and make sure the tires are properly mounted and inflated. It also helps to look over suspension and steering components for obvious wear.
A careful visual check should include sidewall condition, tread surface, valve stems, and any sign of rubbing once the car is on the ground. After installation, a short initial drive followed by a second inspection can reveal clearance issues, vibration, or air loss before the vehicle is used more extensively.
How often should tires on a 2020 Toyota Mirai be inspected?
Tires on a 2020 Toyota Mirai should be inspected regularly, not only by mileage but also by time and storage conditions. A specialty vehicle that is driven less often can still develop age-related concerns such as cracking, air loss, flat spotting, or unnoticed damage between outings.
Monthly pressure checks and a thorough visual inspection before longer drives are sensible habits. It is also wise to inspect after long periods of storage, looking for cuts, bulges, irregular tread wear, or signs that the vehicle has settled on one spot for too long, especially if use is occasional rather than daily.
