Just got a 2013 Prius 5 with the 17" wheels, replacing my 2 that had 15" wheels. Is it crazy to put the 15s onto the "new" car? I use my car for some offroad shenanigans and I'm worried about the thinner sidewalls on rougher roads (plus want to keep my studded snow tires) pros/cons one vs the other?
