I'm just curious. If I get some 17x(8-9), am I still required to use the 205/50-17 even if I get my tires stretched? I know the 17x7 it's not necessary to stretch the wheels.
I am still a noob when it comes to the correct wheel sizes and proper fitment.
205-50-17 tires will fit perfect on rims from 5-5.7" width. Rims with a larger width then that you'll be stretching the tire.
If you're going with ie. 8" width rims and don't want to stretch you can run 225/45 R17 but you might rub(i'm not 100% sure), however im sure rim experts can chime in on this.
PS. for future ref this applies to 4cyl with stock size of 195 65 15
