When running less than 45psi a single wrap of tape is neccasary, when running greater than 45psi a double wrap of tap is required.
Please note that Stan's Yellow Rim Tape by itself is not a tubeless conversion. Traditional (Non-BST) rims require the use of a Stan’s NoTubes rim strip to achieve a secure tubeless setup. Using only Yellow Rim Tape and Stan’s NoTubes sealant on a conventional rim can result in difficult inflation, and catastrophic "burping" issues. Please see our Rim Strips for converting traditional non-tubeless rims.
