The 2024 Toyota Mirai approaches luxury sedan motoring from a distinctly modern angle, pairing sleek four-door styling with hydrogen fuel-cell technology and a quiet, advanced road-car character. Buyers looking at this exact model are usually balancing contemporary drivability with the need to match the car’s wheel setup correctly. The 2024 Toyota Mirai uses radial tires in two primary sizes, 235/55R19 and 245/45R20, so the first decision is confirming whether the car is on 19-inch or 20-inch wheels. From there, the choice centers on tread style, brand, and sidewall treatment, while keeping wheel diameter, overall fitment, and everyday road use in view.
Which Tire Size Is Right for The 2024 Toyota Mirai
The 2024 Toyota Mirai uses two primary tire sizes, and both are radial fitments tied to different wheel diameters. Because this Mirai can be found on either 19-inch or 20-inch rims, the first thing to confirm is the actual wheel size on the car before choosing a tire. Once that is settled, the decision becomes matching the correct metric radial size and then comparing the available product styles within that fitment.
235/55R19 is a modern metric radial size in which 235 refers to nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2024 Toyota Mirai, this size belongs to the 19-inch wheel setup and keeps the selection focused on a contemporary radial fitment rather than vintage-style construction choices. It is the right starting point for owners who want to confirm the original wheel diameter first and then match the tire size exactly before comparing tread and performance-oriented product differences.
245/45R20 is also a modern metric radial size, with a 245-millimeter nominal section width, a 45-series profile, radial construction, and a 20-inch rim diameter. For the 2024 Toyota Mirai, this size applies to the 20-inch wheel configuration and opens up meaningful choice across brands and sidewall styles, including Blackwall, Redline, and raised white letter presentations. Buyers considering this fitment should make sure the car is actually on 20-inch wheels, then compare the available tire series and wheel-width compatibility rather than assuming every 20-inch tire in this size serves the same purpose.
Mirai sub-model fitment stays fairly straightforward because both the Limited and XLE can use the same two primary tire sizes. What matters most is not the trim name by itself, but confirming whether the car is equipped with 19-inch or 20-inch wheels before choosing tires.

2024 Toyota Mirai Limited
The 2024 Toyota Mirai Limited can be equipped with either of the Mirai’s two radial tire sizes, so wheel diameter is the real fitment checkpoint. Tire selection comes down to confirming whether the car is on 19-inch or 20-inch rims and then comparing the available radial options for that setup.
The 2024 Toyota Mirai XLE also uses the same two radial size paths found elsewhere in the model range, which keeps fitment centered on wheel size rather than trim-specific construction changes. That means the safest way to narrow the choice is to verify the actual rim diameter on the car and select the matching metric radial size.
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 2024 Toyota Mirai Tires for Sale
Available 245/45R20 choices span BFGoodrich, Nitto, and Pro-Trac, with several tire series and sidewall treatments to compare. For Mirai owners on 20-inch wheels, the product grid is where Blackwall, Redline, and raised white letter styling can be weighed alongside rim-width range, load figures, and other radial tire details.
These 2024 Toyota Mirai tire FAQs focus on the questions that matter most at this level: choosing between the two correct sizes, confirming 19-inch versus 20-inch wheel fitment, comparing available 245/45R20 tire options, and checking the car before regular road use.
Tire Size & Fitment
What tire size fits a 2024 Toyota Mirai?
The 2024 Toyota Mirai uses two primary tire sizes: 235/55R19 and 245/45R20. Both are radial metric sizes, and each one corresponds to a different wheel diameter, so the correct choice depends on whether the car is equipped with 19-inch or 20-inch rims.
That makes wheel confirmation the first step before ordering tires. Check the tire sidewall already on the car, confirm the wheel diameter, and make sure any replacement matches the Mirai’s actual setup rather than selecting by trim name alone. A tire in the right diameter but the wrong section width or profile can create unnecessary fitment issues.
What size rim does a 2024 Toyota Mirai use?
A 2024 Toyota Mirai can use either a 19-inch or 20-inch rim, depending on the tire size fitted to the car. The 235/55R19 size belongs to a 19-inch wheel, while the 245/45R20 size belongs to a 20-inch wheel.
That difference matters because tire size and wheel diameter have to match exactly. Before replacing tires, confirm the actual wheels on the vehicle and do not assume every Mirai uses the same diameter. If the car has had wheel changes since new, the current wheel diameter and width should guide the selection rather than the trim badge.
Do all 2024 Toyota Mirai sub-models use the same tire size?
The 2024 Toyota Mirai Limited and 2024 Toyota Mirai XLE can both use the same two primary tire sizes, 235/55R19 and 245/45R20. That means fitment is shared across the covered sub-models, but not every individual car will be on the same wheel diameter.
In practice, trim level alone does not settle the tire choice. A Mirai owner should still confirm the size already mounted on the car or verify the wheel diameter directly before replacing tires. That keeps the search focused on the correct fitment and avoids choosing a 19-inch tire for a car that is currently running 20-inch wheels.
Choosing the Right Tire
What should I consider when choosing a tire for a 2024 Toyota Mirai?
Start with the correct size for the car’s actual wheel setup, since the 2024 Toyota Mirai uses either 235/55R19 or 245/45R20. From there, compare construction, sidewall style, rim-width compatibility, load figures when shown, and the overall character of the tire series that fits your intended use.
For most owners, the real question is whether the tire suits the car’s current wheels and how the vehicle will be driven. A daily-use Mirai, a low-mileage garage-kept example, and a car with appearance priorities may lead to different choices. Matching the correct size first keeps those later comparisons meaningful.
What sidewall styles are available for 2024 Toyota Mirai tires?
For the 245/45R20 fitment used on some 2024 Toyota Mirai applications, available sidewall styles include Blackwall, Redline, and RWL, or raised white letter. Those options give the 20-inch setup a wider appearance range than a single plain sidewall treatment would.
Sidewall style does not change the need to match the correct tire size and wheel diameter, but it can change the visual character of the car considerably. Blackwall keeps the look understated, while Redline and raised white letters add more visual emphasis. Buyers focused on presentation should compare sidewall treatment alongside brand, tire series, and wheel compatibility.
What brands offer tires for the 2024 Toyota Mirai?
Within the available 245/45R20 fitment for the 2024 Toyota Mirai, brands include BFGoodrich, Nitto, and Pro-Trac. Those choices appear across several radial tire series, giving buyers more than one path depending on whether the priority is appearance, series preference, or specification details.
Brand should be compared alongside the exact size, rim-width range, sidewall style, and any load information shown for the tire. That keeps the decision grounded in fitment rather than name alone. It also helps separate a styling-driven choice, such as Redline or raised white letters, from a more conventional Blackwall replacement.
Restoration & Appearance
Which tire should I choose for a period-style 2024 Toyota Mirai?
A period-style approach on a 2024 Toyota Mirai is less about vintage construction and more about preserving the car’s intended modern proportions and wheel presentation. The best starting point is the exact size already matched to the car’s wheel diameter, either 235/55R19 or 245/45R20, using a radial tire that keeps the Mirai’s overall stance in line with its original design language.
Appearance then comes down to tire series and sidewall treatment rather than bias-ply versus radial decisions. On 20-inch applications, Blackwall, Redline, and raised white letter options create noticeably different visual results. Buyers seeking a strict as-delivered look should compare the current car carefully with original vehicle documentation before making a style-driven change.
Which sidewall style suits a period-style 2024 Toyota Mirai?
For a 2024 Toyota Mirai, a period-style look usually means keeping the tire visually in step with a modern premium sedan rather than adding an overtly nostalgic presentation. In the available 245/45R20 options, Blackwall offers the most restrained appearance, while Redline and raised white letter versions create a more customized visual statement.
The right choice depends on whether the goal is a clean contemporary look or something that stands out more at the curb. Sidewall treatment should still be a secondary decision behind correct size and wheel compatibility. Buyers who care about preserving the Mirai’s original visual tone should verify how the car was delivered before changing to a more expressive sidewall style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2024 Toyota Mirai?
Yes, modifications can affect tire fitment on a 2024 Toyota Mirai even when the tire size looks close to stock. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or body modifications can influence clearance at the fender, steering components, and inner wheelhouse.
That is why the current setup matters more than assumptions based on model year alone. A Mirai with non-original wheels may require extra attention to diameter, width, and available space around the tire. Before replacing tires, inspect the car as it sits now and make sure the chosen size matches both the wheel and the vehicle’s actual clearances.
What should I inspect before driving a 2024 Toyota Mirai on new tires?
Before putting a 2024 Toyota Mirai into regular service on new tires, inspect wheel diameter and width, verify the installed tire size, and confirm that inflation is set appropriately for the tire and vehicle application. It is also smart to look over valve stems, wheel condition, and basic clearance with the steering turned.
A short initial road check can reveal issues that are easier to correct early, such as vibration, rubbing, or uneven seating. After a brief drive, recheck pressure and look for any signs of contact around the inner fender or suspension area. That process matters even more if the car has different wheels than it left the factory with.
How often should tires on a 2024 Toyota Mirai be inspected?
Tires on a 2024 Toyota Mirai should be inspected regularly, not just when tread looks worn. A routine visual check for pressure loss, uneven wear, cuts, bulges, or sidewall damage helps catch problems before they become more serious, especially on a car that may alternate between daily use and longer parked periods.
Monthly checks are a sensible habit, with added attention before highway travel or seasonal temperature changes. The owner should also inspect after pothole strikes or curb contact, since wheel and tire damage is not always obvious right away. Keeping an eye on wear pattern and inflation can also help reveal alignment or suspension concerns early.
