what tire size?

[burrpenick]

Currently have 15x10 deep dish Cragars on rear of my Duster; want something that does not protrude as much.......found a set of new 15x6 Cragars but need to know what tire I could mount safely on that width rim that would LOOK OK with the 14" x 7 Cragars that are now up front. I plan to buy 4 new tires, so I can match the sizes when buying. I do want a somewhat larger/wider tire out back.

Thanks, George in Tallahassee
