Can I convert my non-tubeless mountain bike rim to tubeless with tape and valve only?

No. "Tape and Valve" conversions are only appropriate with rims that are labelled as "Tubeless Ready," "Tubeless Compatible," or similar. The BST (Bead Socket Technology) profile developed by Stan's NoTubes was a departure from traditional bicycle rim design and its core concept is the basis for the vast majority of "tubeless-ready" rims and wheels on the market today. Stan's Yellow Rim Tape is not, by itself, a tubeless conversion for older, traditional, non-"tubeless-ready" rims. These older rims require the use of a Stan’s NoTubes Rim Strip (now discontinued) to re-shape the rim bed to achieve a safe, secure tubeless setup. While we would recommend considering a new tubeless-ready wheelset in place of a rim strip conversion, Stan's Rim Strips and kits may still be available at your local bike shop and can be used to convert vintage bikes with older, non-tubeless-ready rims. Using only Yellow Tape and Stan’s Sealant on a non-tubeless-ready rim can result in not only difficult inflation during set-up, but catastrophic "burping" issues while riding. While Stan's Rim Strips have been discontinued, we continue to provide information and resources to assist in converting non-tubeless-ready wheels.
