Hi, what is the smallest rim size that will fit in to 2011 volvo xc 60 t6? I'm trying to save money on getting smaller winter tires. Thank you.

 

Not sure of the smallest diameter, but going to a smaller tire is going to change the speedometer and odometer readings, unless you get a tire with a really tall sidewall to make it the same diameter. That might look funny and likely not be any cheaper. It's also be really mushy feeling.
