Hi can anyone on 6 wide wheels let me know some good stretches?

I currently have 16×8 wheels with 195/45 tires. they stretch pretty nice and were exactly what i was going for. 16×8 is very popular so it wasnt hard to find good looking specs.

now i picked up some gsr blades (for fitment reasons). they are 15×6 and they give way more clearance to my fenders, but the tires are too big and have no stretch.

can anyone guide me to a size that would look identical or similar to what setup i have right now?

I saw a few 165/50 that look decent but they are all on 15×6.5 wheels. mine are only 15×6
