Early this year I bought a set of Magnum 500s (15x6) from Lee DeLaBarre. They were from a '70 Avanti he was parting out. I cleaned them up and in the spring I got a set of Firestone 215x75x15 tires put on (weights on the inside). After putting new six-leaf springs on my wagon, rebushing the old six leafs, installing them and front spring spacers on my '64 Daytona convertible, I finally got the Magnums put on. I'm pretty happy with the way they look and they sure make a good argument for not running larger radials on the skinny 4 1/2" Lark rims. I had 205x75s on the stock rims and they always looked soft because of the way the beads were pinched inward making the sidewalls pooch out. The 215s on six-inch wheels don't show that at all.
