The 275/35R22 fitted to the 2018 Volvo XC90 has a section width of 275mm and an aspect ratio of 35%, mounted on a 22-inch rim. That gives a sidewall height of 96.3mm (3.79") and an overall outside diameter of 751.3mm (29.58").

For a softer ride or winter setup, a 265/41R21 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 2018 Volvo XC90 uses a 5x108 bolt pattern with a 63.4mm hub bore. Safe rim width range for the OEM tire is 8.5J â 9.5J, and offsets in the ET34 â ET44 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2018 Volvo XC90 is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
