Hello I have the 2016 iSport hatchback. I have had it for about a year and a half now. I've been doing research but I know absolutely nothing about car tires. I've seen some really nice 215 45 18 but they weren't on the sport. Can I go up in size from the stock 16? Tire rack says only 205/60-16 will fit my car. What if I wanted a lower profile tire if I have to stay with 16 in. My car looks like it has the clearance there's a lot of space. Any tips and advice would be appreciated.
