I blew a tube then destroyed an XL tire. Have a spare but the tube i had was dry rotted. Went to get it mounted and dealer thought that it probably blew because it was the wrong size. The one that blew was for a low-boy tire 1000-15. He thought it should have an 1100-16, but was unable to locate one with a truck type stem (tr444 or tr150). Thanks in advance.
