Looking to replace older wheels and tires on my '63. Have been running 15 x 6" Magnum 500 rims with P20575R15 tires for many years. Looking to install newer Mag 500 rims either 15 x 6" with a P20575R15 tire or upgrading to a 15 x 7" with a P215? Any comments appreciated about going to a larger rim and tire combo? Thanks.
