downsizing rims and tires?
 

I put four mounted snows on my 2012 i-touring (pre-skyactiv) and just swapped them back with my spring/summer tires. Both the snow and OEM tires are 205/55R16

I am interested in trading the car for a 2015 s Touring hatch. Google tells me the OEM tire size is P215/45R18. (But for the 2015 Sport model, the OEM tire is P205/60R16, close to the size of my snow set).

Should I be able to put my 16" snows (next fall) on the 2015 s Touring without a problem?

Thanks -
