Daniel, Robb F told me to take a block of wood and some 80 grit. Put a belt on, then carefully hold the block to the wheel until it's flat again. Mine had developed a low area in the center because I put a lot of pressure there when profiling. The sanding block took care of the problem in about a minute. Gotta be a little careful doing it though. Now if you need a complete new tire, that's a different story and I can't help.
