Alright little lesson about stance lol
If you run a 215/40/17 tires then it will give you a stretched tire. Its not dangerous unless you run a 215 on a 10.5J sized wheel which is a huge stretch. If you run 215 all around you might need to slightly roll your fenders but only of your really low.
I also have fender roller and I roll fenders if you want me to do them for you. LMK buddy
