I'm in Vacaville about to train with HPAT this weekend and noticed the Legacy nose is flat.  There isn't a whiff of anyone with parts or knowledge nearby, including the FBO, and I have not brought any tools or spare parts.   Can someone tell me what I need to do to get the tube changed (tools, procedures) and possibly where to source a 11x4-5 tube?   Thanks in advance, Paul 321-214-1724.
