What did most of the top customs of 1963 have in common? Well, according to the '63 Custom Car Yearbook (and my memory) they all used these unique, futuristic tires. Introduced in 1959, the US Royal Masters featured the very first narrow whitewall, beating Detroit by two or three years. With their radiant ribbing on the black part of the sidewalls and extended curb-protective rib surrounding the white part, these things were downright exotic (and expensive). That's why they were the choice of Winfield, Stuckey, Starbird, Cushenbery and Farhner, who used them on the Jade Idol and Solar Scene, the Eclipse and the Matador among many others. In fact, there were 24 other cars with Masters in that Annual, which stands as the definitive publication on customs of that era.
