I've got a nail in my relatively new rear tire and am currently trying to repair. I removed the tire and patched on the inside however I still had an air leak through the hole when I remounted it. Fortunately I have access to a pneumatic tire machine so it's not a huge job like it would be otherwise. Currently waiting for the glue to set this time completely, with a new patch. The problem is the inside of the tire has ribs and a plasticy finish so the patches do not adhere well. I'm hoping it was only my haste in not letting the glue set. Any suggestions if this turns out not to work?
