The AVON stickers are from
www.tirestickers.com. They don't show the lettering style on their website but if you call them they can ship them to you if you explain what you're looking for. This is the second set of tires I've applied them to. Very good product. The tires are DOT rated. The two main importers that I'm aware of in the U.S. are
www.rogerkrausracing.com and
www.sascosports.com Kraus Racing is in California. Sasco is in Virginia.
Here is the current pricing sheet from Kraus Racing.
