Stan's Rim Tape
This rim tape can be used to seal most ZTR rims air tight including the ZTR 355, ZTR 355 29er and ZTR Olympic, ZTR Alpine, and ZTR Crest.
It can also be used as a light weight rim tape.
My only issue I had with this tape was it would split as it was coming off the roll if I was putting too much pressure on it. Otherwise it works great. Could be a bit cheaper...
