Stan's Yellow Tape is designed to work with tubeless-ready rims and wheels. If you'll be inflating your tires to 45psi or less; one layer of yellow tape in the bed of your rim is all you need for most rims. For road tubeless and similar tires that require more than 45psi of pressure; a double wrap of tape is required.Creates durable, airtight seal over spoke holesCompletely non-porous vapor barrier seals rim interior from moistureNatural gum rubber adhesive sticks where and when you want it to but leaves no residueLow friction surface helps tire beads slip into place----
