snow tire issue
 

I live in MT, I own a 2014 mazda6 grand I touring, every tire place Ive been too dont carry my tire size 225/45 R19 snow tire for my car. Im being told this is considered a sport car. Why is there not a snow tire for this size. And If ive of known of this problem I wouldnt bought this car. I wouldve kept my 2006 mazda 6 sport size 17, there I had 2 sets of tires and rims. And was never stuck for 3 years now.
