I'm pretty sure wheels on S90 are larger in diameter, so you would have to install different tires. Bolt pattern is 5x108 and you would need to get different size hubcentric rings. To find out if these wheels will actually fit your car, go to tirerack.I'm interested in these, but need to figure out if they would fit my 2018 S90. What is the size of the hub as I would need different adapters? Is the bolt patter 5 x 108?
