I'm planning on buying some tires from these guys when I meet them at the San Jose Vintage Motorcycle show again this year. I looked up their website just for fun so I posted it below if anyone wants to see their shop. Here is some more information I typed up in response to another persons question: The guys at
www.Heidenauusa.com know vintage tires well. I talked to them at the San Jose Vintage Bike show and they had an answer for everything I asked which is not an easy task. The reps business I talked to was
Moto Amore and his address is 2983 Lafayette St. Santa Clara, CA 95054. Phone is:1-408-295-3004. They have a cute website here
http://www.moto-amore.com. Any business that still has it's doors open and is offering over the top service or help is one I'll shop at.
Spokes also let loose his secret source for buying vintage tires:
http://www.universaltire.com/ They have a pretty awesome selection of brands and sizes and if you need tires for your vintage military vehicle you are in luck!! I'm going to call them to see if they will send me one of their free, snazzy looking catalogs.
