Where did you find the triple whites?? I'd like to go that route on my Imperial one of these days, but right now, I have new Kumho radials with maybe 300 miles on them!
Patrick. I took measurements and pictures of the original spare tire and sent all the specs to Diamond Back Tires. They will vulcanize any sort of white/colored wall design you can think of. They have an excellent reputation as well and I have many friends whom have gone the same route.
