Need help with fitment.

[bmunz25]

So I just got an E30 and I'm about to order 16x8 in front and 16x9 in rear. I want to stretch the tires but not an aggressive fitment. What tires would give me a moderate stretch. How about 195/45 for 16x8 and 205/45 for 16x9? Also my buddy gave me a set of tires with 205/50 r15 tires, is it possible to put a 15 on a 16?
Thanks!

you cant put 15" tires on a 16. you want to do 16x9 in REAR and 16x8 upfront. sizes you chose work for a good stretch. you need to do some research
