I have wheel vintiques 15x8 all the way around on my car. All lowered with Hotchkis springs.
I used 235/60/15 FireHawk Indy 500 tires (no longer made). The tires are 25.5 tall. I get a slight rub on the front when turning on one side and paper thin clearance on the other.
Plenty clearance on the back. I wanted all 4 tires the same so 235 is as wide as I can go.
