I have a 2019 v90 t6 awd and drive lots of winter/mountain snow. Advice on winter tires. Advise on 18, 19 or 20" wheels. Thanks

 

Have a T8 and put on 18" wheels with Nokian Hakkapeliitta 9's studded, would like a 17" wheel for more sidewall rubber but the T8 has large brake rotors, studs for stopping(;

 

Agree on downsizing to shorter rims if possible - that gives you a taller sidewall for pot hole protection and narrower tread widths help cut through the snow rather than floating on top. Nokians are a top choice. A good resource is wheel-size.com to see what choices in tire size are appropriate for your model.

 

18's,,, I went w Cooper Discoverer M&S 245/55R18.
V90 CC
