The 2025 Toyota Mirai stands apart in the modern sedan market with its hydrogen fuel-cell powertrain, sleek proportions, and upscale touring character. It is the kind of vehicle where quiet road manners, refined ride quality, and contemporary wheel styling all play into tire selection more than nostalgia or restoration concerns. For this exact Mirai, tire fitment centers on two radial sizes, 235/55R19 and 245/45R20, both tied to a 19- or 20-inch wheel setup. Available choices lean modern, with blackwall performance-oriented options joined by redline and raised white letter alternatives in 245/45R20. The key is matching the tire to the wheel package already on the car before comparing style, series, and road-use priorities.
Which Tire Size Is Right for The 2025 Toyota Mirai
The 2025 Toyota Mirai uses two primary tire sizes, and the first step is confirming which wheel diameter is on the car. One setup uses a 19-inch rim with 235/55R19, while the other uses a 20-inch rim with 245/45R20. Because the same XLE sub-model can appear with either size, the real decision starts with wheel confirmation and then moves to tire series, sidewall style, and intended driving use.
235/55R19 is a modern metric radial size in which 235 identifies the nominal section width in millimeters, 55 is the aspect ratio, R marks radial construction, and 19 is the wheel diameter in inches. On the 2025 Toyota Mirai, this size supports a contemporary touring fitment built around a 19-inch wheel package. Its sizing points toward buyers who want to stay with the Mirai's 19-inch setup rather than move into the 20-inch fitment path. Before choosing within this size, confirm the actual wheels on the car, especially if it was purchased used or has been modified.
245/45R20 is also a modern metric radial size, with 245 representing nominal section width in millimeters, 45 indicating a lower-profile sidewall, R for radial construction, and 20 for wheel diameter. For the 2025 Toyota Mirai, this size belongs to the 20-inch wheel setup and brings the widest product variety on the page. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, redline, and raised white letter sidewall treatments across several tire series. It is the size to evaluate carefully if appearance, series choice, and wheel-package confirmation are all part of the decision.
Sub-model fitment is straightforward here, but tire choice still depends on the wheel package already fitted to the car. The 2025 Toyota Mirai XLE appears with both primary sizes, so confirming whether it carries 19-inch or 20-inch wheels matters before comparing tires.

2025 Toyota Mirai XLE
The 2025 Toyota Mirai XLE uses either 235/55R19 or 245/45R20, both in radial construction, so the sub-model name alone does not narrow the fitment to one size. Tire selection starts with the wheels on the car, then moves to whether a straightforward blackwall option or a more appearance-driven sidewall treatment suits the setup.
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.

For the 2025 Toyota Mirai, the main questions center on which of the two tire sizes applies, how the wheel diameter affects fitment, and how to compare modern radial options by series, sidewall treatment, and vehicle setup.
Tire Size & Fitment
What tire size fits a 2025 Toyota Mirai?
The 2025 Toyota Mirai uses two primary tire sizes: 235/55R19 and 245/45R20. Both are radial sizes, and each one corresponds to a different wheel diameter, so they are not interchangeable choices on the same rim.
The practical step is to confirm whether the car has 19-inch or 20-inch wheels before selecting a tire. Since the Mirai XLE can appear with either size, checking the existing sidewall markings or wheel diameter is more reliable than assuming fitment from the trim name alone.
What size rim does a 2025 Toyota Mirai use?
A 2025 Toyota Mirai uses either a 19-inch rim with 235/55R19 tires or a 20-inch rim with 245/45R20 tires. The tire size and rim diameter are paired together, so each size belongs to its own wheel setup.
That makes wheel confirmation the first fitment check on this car. Looking at the current tire sidewall, verifying the wheel itself, and checking for any past wheel changes will help prevent ordering the right tire size for the wrong rim diameter.
Why does the 2025 Toyota Mirai have more than one tire size?
The 2025 Toyota Mirai has more than one tire size because it can be configured with different wheel diameters. One fitment uses 235/55R19 on a 19-inch rim, while the other uses 245/45R20 on a 20-inch rim.
That means the size decision is really a wheel-package decision first, not simply a matter of preference. A buyer should verify the exact wheels currently on the car, especially if it was bought secondhand or has aftermarket wheels, before comparing tire series or sidewall appearance.
Choosing the Right Tire
What should I consider when choosing a tire for a 2025 Toyota Mirai?
Start with the correct size and wheel diameter for the car, since the 2025 Toyota Mirai uses either 235/55R19 or 245/45R20. After that, compare the available tire's construction, sidewall style, rim-width specification, and how its series fits the way the car is driven.
For a Mirai already on 20-inch wheels, the visible differences include blackwall, redline, and raised white letter presentations across multiple radial series. Buyers who want a cleaner modern look may focus on blackwall options, while appearance-minded owners may prefer a more distinctive sidewall treatment.
What sidewall styles are available for 2025 Toyota Mirai tires?
Within the available 245/45R20 products for the 2025 Toyota Mirai, sidewall choices include Blackwall, Redline, and RWL, which means raised white letter. Those options let the same basic size take on a different visual character depending on the tire selected.
Sidewall style does not change the need to match the tire to the correct wheel diameter and size. Once that fitment is confirmed, the choice becomes one of appearance and product character, especially if the car is used as a daily driver, a weekend cruiser, or a more personalized modern sedan.
What brands offer tires for the 2025 Toyota Mirai?
Available 245/45R20 tires for the 2025 Toyota Mirai include products from BFGoodrich, Nitto, and Pro-Trac. Those options cover several radial series, giving the buyer more than one path within the same primary size.
The best way to compare them is by size accuracy, wheel compatibility, sidewall appearance, and series character rather than by brand name alone. Checking rim-width guidance and deciding whether the car should keep a subtle blackwall look or use a more expressive sidewall style can narrow the field quickly.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Toyota Mirai?
Yes, modifications can affect tire fitment on a 2025 Toyota Mirai. Wheel changes, suspension alterations, and changes in offset can all influence whether the correct tire size clears the fenders, suspension, and steering components the way it should.
A Mirai with aftermarket wheels should be checked carefully before replacing tires by size alone. Confirming wheel diameter is only the start; wheel width, offset, and visible clearance at full steering lock matter too, especially when moving between the car's 19-inch and 20-inch fitment paths.
What should I inspect before driving a 2025 Toyota Mirai on new tires?
Before driving a 2025 Toyota Mirai on new tires, inspect the wheel size, confirm the tire size matches the car's setup, and look over the wheels for damage or poor bead seating. Tire pressure should also be set correctly, and the tires should be checked for any visible shipping or mounting issues.
A short initial drive followed by another visual inspection is a smart habit. Watch for rubbing, unusual vibration, or uneven clearance, particularly if the Mirai has replacement wheels or prior suspension changes, since correct size alone does not rule out setup-related fitment problems.
What should I check before a longer drive in a 2025 Toyota Mirai?
Before a longer drive in a 2025 Toyota Mirai, check tire pressure, tread condition, and the sidewalls for cuts, bulges, or cracking. It is also worth confirming that the car is wearing the correct 19-inch or 20-inch tire package and that there are no signs of air loss.
Longer trips put more emphasis on small issues that might be easy to overlook in local driving. A quick review of wheel fastener tightness, general alignment feel, and any contact marks inside the wheelwell can help catch fitment or maintenance problems before they turn into a roadside interruption.
