Wheels and Tires Inner Tubes ? July 13, 2015 Anybody seen an inner tube for a 27×14 tire ? I can find them for 12" tires all day long, but not 14". I’ve got a dry rotted tire I’d like to use as a spare, but can’t find a tube for it. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
