'54 Kaiser Special in need of tires. Current tires are 13 yrs. old, "Thoro" brand, 215/75/15N radial with almost a 3" whitewall. I like the current tire and whitewall size. Have found that DB Tires and Coker are possible sources for replacements. Car has the factory wire wheels it came with and tubes in them. Any advice, experience or source of replacements will be appreciated, please.
