The 2025 Volvo Trucks EX90 brings a modern electric luxury-SUV approach to tire fitment, with wheel and tire combinations that reflect both its upscale positioning and its substantial curb presence. Rather than using one universal setup, the EX90 spans staggered front-and-rear fitments across 20-, 21-, and 22-inch rim diameters, so identifying the exact wheel package is the first step before selecting tires. Every primary fitment here is a radial metric size, including 255/50R20, 265/45R21, 265/40R22, 285/45R20, 295/40R21, and 295/35R22. That makes the real choice less about bias-ply versus radial and more about confirming front or rear position, rim diameter, and the tire profile that matches the vehicle’s current setup.
Which Tire Size Is Right for The 2025 Volvo Trucks EX90
The 2025 Volvo Trucks EX90 uses six primary tire sizes, and the correct one depends on both axle position and wheel diameter. Front and rear sizes are staggered, and the vehicle appears with 20-, 21-, or 22-inch rims, so the first step is confirming whether you are matching a front or rear tire and which wheel package is on the vehicle now.
255/50R20 is a metric radial size in which 255 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the EX90, this size serves as a front fitment in a 20-inch package rather than a universal size for every configuration. Its dimensions place it in the same overall diameter range as the other EX90 fitments while using a taller sidewall than the larger-wheel alternatives. This size should be matched carefully to the correct front wheel setup before replacement.
265/40R22 is a metric radial size with a 265-millimeter nominal section width, a 40-series profile, and a 22-inch rim requirement. For the 2025 Volvo Trucks EX90, it is used as a front fitment on certain 22-inch wheel combinations, making wheel diameter confirmation essential before selection. Compared with the 20-inch front option, this size uses a lower-profile sidewall while staying close in overall diameter. It is the right size to evaluate when the vehicle carries the larger 22-inch front wheel package and the goal is to maintain that existing configuration.
265/45R21 follows the same modern metric radial format: 265 millimeters of nominal width, a 45-series aspect ratio, radial construction, and a 21-inch rim diameter. On the EX90, this is a front tire size used with a 21-inch wheel setup, so it should be treated as a position-specific fitment rather than a full-vehicle size by itself. Its profile sits between the taller 20-inch setup and the lower-profile 22-inch alternative. This is the size to consider when replacing front tires on an EX90 equipped with 21-inch wheels and matching the original front-to-rear stagger.
285/45R20 is a metric radial size in which 285 is the nominal width in millimeters, 45 is the aspect ratio, and 20 is the rim diameter in inches. On the 2025 Volvo Trucks EX90, this size is used at the rear with the 20-inch wheel package, giving the vehicle a wider rear tire than the corresponding 255/50R20 front fitment. That wider rear specification is part of the EX90’s staggered arrangement and should be preserved unless the wheel and vehicle setup have been intentionally changed. Rear tire replacement should therefore start with axle position and wheel diameter confirmation.
295/35R22 is a wide, low-profile metric radial size with a 295-millimeter nominal section width and a 22-inch rim diameter. For the EX90, it is a rear fitment paired with the 265/40R22 front size on certain 22-inch configurations, so it belongs to a staggered package rather than a square setup. Its short sidewall and broad tread section make correct wheel match especially important. This size should be chosen when the vehicle already carries the 22-inch rear wheel package and the goal is to maintain the proper rear specification.
295/40R21 is a metric radial size that combines a 295-millimeter nominal section width with a 40-series profile and a 21-inch rim. On the 2025 Volvo Trucks EX90, it serves as the rear companion to the 265/45R21 front fitment, making it part of the vehicle’s 21-inch staggered arrangement. Its width distinguishes it clearly from the front size, even though the overall diameter stays in the same general range as the rest of the EX90 combinations. This is the correct rear size to evaluate when replacing tires on an EX90 equipped with 21-inch wheels.
EX90 tire fitment varies by front or rear position and by wheel package, so checking the exact sub-model location matters before choosing a tire. The Plus and Ultra configurations do not all use the same combinations, and 20-inch fitments differ from the 21- and 22-inch setups.

2025 Volvo Trucks EX90 Plus Front
The 2025 Volvo Trucks EX90 Plus Front uses one of three radial front sizes, depending on whether the vehicle carries 20-, 21-, or 22-inch wheels. Tire selection starts with confirming the installed front rim diameter, then matching the correct metric size to preserve the vehicle’s staggered front-to-rear setup.
The 2025 Volvo Trucks EX90 Plus Rear uses a wider rear radial size that changes with the 20-, 21-, or 22-inch wheel package. Rear replacement should match both axle position and rim diameter so the EX90 keeps the intended staggered relationship between front and rear tires.
The 2025 Volvo Trucks EX90 Ultra Front uses radial front fitments tied to either a 21-inch or 22-inch wheel package. That makes wheel confirmation especially important, since the correct replacement depends on matching the current front wheel diameter and maintaining the proper paired rear setup.
The 2025 Volvo Trucks EX90 Ultra Rear uses wider radial rear sizes corresponding to the vehicle’s 21-inch or 22-inch wheel package. Tire selection here should focus on matching the exact rear rim diameter and keeping the correct staggered fitment rather than treating the EX90 as a single-size application.
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.
Frequently Asked Questions
EX90 tire questions usually come down to identifying the correct front or rear size, confirming whether the vehicle has 20-, 21-, or 22-inch wheels, and understanding how the staggered setup affects replacement choices. The answers below focus on exact fitment, selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2025 Volvo Trucks EX90?
The 2025 Volvo Trucks EX90 uses six primary radial tire sizes: 255/50R20, 265/45R21, and 265/40R22 at the front, plus 285/45R20, 295/40R21, and 295/35R22 at the rear. The correct size depends on the wheel package and on whether the tire is for the front or rear axle.
That means the first step is not choosing a brand or tread style, but confirming the installed wheel diameter and axle position. An EX90 with 20-inch wheels uses a different front-and-rear pairing than one with 21- or 22-inch wheels, so replacement should match the vehicle’s current staggered setup unless the wheels have been intentionally changed.
What size rim does a 2025 Volvo Trucks EX90 use?
The 2025 Volvo Trucks EX90 appears with 20-inch, 21-inch, or 22-inch rim diameters, depending on the tire package on the vehicle. Those diameters correspond to the six primary tire sizes, with separate front and rear fitments in each wheel family.
Rim diameter should be verified directly on the wheel or from the current tire sidewall before ordering replacements. Since the EX90 uses more than one wheel size across its front and rear combinations, assuming the rim diameter from appearance alone can lead to choosing the wrong tire profile or the wrong staggered pair.
Why does the 2025 Volvo Trucks EX90 have more than one tire size?
The 2025 Volvo Trucks EX90 has more than one tire size because it uses different wheel packages and staggered front-to-rear fitments. Front sizes are narrower than rear sizes, and the vehicle is configured around 20-, 21-, or 22-inch rims depending on the version and wheel setup.
That variation is normal for a modern premium SUV with multiple wheel options, but it makes replacement more exacting. Matching only one number from the sidewall is not enough; the correct approach is to confirm the full size code, the axle position, and the installed wheel diameter so the replacement tire stays aligned with the vehicle’s present configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2025 Volvo Trucks EX90?
Start with the basics the EX90 actually requires: front or rear position, full tire size, and rim diameter. Since this vehicle uses staggered radial fitments across 20-, 21-, and 22-inch wheels, the right choice begins with matching the exact size already used on that axle.
After that, compare practical details such as whether you are replacing a single tire or a full axle set, whether the wheel setup is still original to the vehicle, and whether the remaining tires match in size family and wear condition. Keeping the proper front-to-rear relationship matters more here than treating the EX90 like a one-size application.
How do I choose between the available EX90 tire sizes if more than one appears for the 2025 Volvo Trucks EX90?
More than one size appears for the 2025 Volvo Trucks EX90 because the vehicle was configured with different wheel diameters and staggered front and rear combinations. The correct choice is not a matter of preference between those six sizes; it is the size that matches the wheel and axle position already on the vehicle.
A 20-inch EX90 setup uses a different pair of sizes than a 21-inch or 22-inch setup, and front fitments are not interchangeable with rear fitments just because the overall diameters are similar. Checking the current tire sidewall and wheel size before replacement is the most reliable way to stay with the proper fitment.
Why does front and rear tire position matter on a 2025 Volvo Trucks EX90?
Front and rear position matters on the 2025 Volvo Trucks EX90 because the vehicle uses staggered sizing. The front axle uses narrower tires such as 255/50R20, 265/45R21, or 265/40R22, while the rear axle uses wider companions such as 285/45R20, 295/40R21, or 295/35R22.
That stagger means a tire that is correct for one axle may be wrong for the other even when the rim diameter looks related. Replacing tires by axle position helps preserve the intended wheel-and-tire balance, and it also reduces the risk of mounting a rear-width tire on the front or mixing profiles across the same wheel package.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Volvo Trucks EX90?
Yes, modifications can affect tire fitment on a 2025 Volvo Trucks EX90 even when the original tire size seems close. Aftermarket wheels, changes in wheel width or offset, suspension alterations, and ride-height changes can all influence how a front or rear tire sits within the wheel opening.
That matters even more on the EX90 because its fitment is already staggered and tied to specific 20-, 21-, or 22-inch wheel packages. A modified vehicle should be checked for steering clearance, inner-fender clearance, and correct wheel sizing before replacement, rather than assuming the stock tire code will behave the same on a changed setup.
What should I inspect before driving a 2025 Volvo Trucks EX90 on new tires?
Before road use, inspect tire pressure, confirm that each tire matches the correct front or rear size, and look for any mounting or clearance issues once the wheels are back on the vehicle. The EX90’s staggered layout makes a final position check especially important after installation.
A short visual inspection should also include sidewall condition, valve stems, and even spacing around suspension and body components at normal ride height. After a brief drive, recheck for air loss or rubbing and make sure the 20-, 21-, or 22-inch wheel package remains correctly paired from front to rear.
What should I check before a longer drive in a 2025 Volvo Trucks EX90?
Before a longer drive, verify that the EX90 is wearing the correct front and rear tire sizes for its wheel package and that all tires are properly inflated. Inspect tread and sidewalls for cuts, bulges, cracking, or any sign of impact damage that could matter more at sustained highway speeds.
A longer trip is also a good time to confirm that no recent wheel change, tire rotation attempt, or service work disturbed the vehicle’s staggered arrangement. Looking over the 20-, 21-, or 22-inch setup carefully before departure helps catch mismatched axle positions, slow leaks, or clearance issues before they become roadside problems.
