My 53 Dodge restoration had 710-15 as the original tires. I want to get as wide a white wall as possible. In 4ply bias I have found acceptable tires from Goodyear, BFGoodrich and in 6ply from Lester. I know nothing about Lester. In radial Diamondback has a 215/758 15 but the white wall is 7/8 to 1 inch narrower. I know nothing about Diamondback either. I might accept the narrower WW if the difference between radial and bias ply matters. Any advice? Have any of you had good or bad experiences with Lester or Diamonback? Thanks Stan
