I have 15X6 72-spoke Daytons on my BJ8 (1967 3000), with 185/70 Vredesteins. The wheels/tires stick out about an inch from the sides of the wheel wells. I like the 'oversized' look, but some might not.
No problem with rubbing in the front, even at full lock, but the insides of the tires sometimes slightly rub the heads of the bolts that secure the rebounder box on the inside of the rear wheel wells during hard cornering.
