So I searched the web and quickly searched the forum for an answer, but found nothing conclusive. And defiantly nothing Volvo Specific. Here's the story:
I have a 2019 Volvo XC90 which came from the factory with 275 40 R21 Pirelli's mounted on 21x9 wheels.
I was given a set of winter tires also in 275 40 R21, which I'd like to mount on a separate set of wheels. I have a line on a set of Volvo Polestar 21x8.5 wheels for a great price.
Will 275's fit on them? Does 1/2 an inch really make that big of difference?
