i use these guys http://www.rangerpaint.com/
this is a Royal Vogue the yellow i custom mixed and applied with a special pinstriping tool. the paint was about 15$ you get 2 cans a base and color.
theyre great to deal with. i suggest that if youre going to paint the tire to wipe the everliving hell out of it with acetone to make sure it bonds
I tried Ranger tire paint on my tires. A vintage Schwinn with yellow-wall tires looks beautiful... or at least mine did, for all of twenty minutes of riding(!), until the paint started flaking off. This was following Ranger's advice about prep and application.
I didn't try "wiping the everliving hell" out of the tires with acetone first, mainly because (according to Ranger's FAQ) I didn't think I _had_ to.
Has anyone else out there had better luck with tire paint, whether Ranger's or someone else's? If so, if you got durable results, and by "durable" I mean "stayed on for at least a year, and I rode the bike too", what did you do? I'm all curious.
-Edit: I've been exchanging e-mails with the people at Ranger, and they're trying to figure out why the paint adherence failed. So FWIW, they are standing behind their product. Hopefully I'll have another update in a few weeks.
