Tubless rims with non tubeless tires -- what rim tape?
Tubeless tape is an acceptable substitute for any rim strip and, in many cases, will likely be an improvement over factory-installed rim strips. Just be certain to apply the correct width of tubeless tape (it should cover the entire width of the rim's interior from bead to bead) and prepare the rim's interior surfaces well by thoroughly cleaning/removing any residue from the previous rim strip adhesive, and any single threads from the beads if it was a cloth type of rim tape. Also ensure that the valve body hole is taped over first, then punctured only as much as is absolutely necessary to press the valve through as that helps with forming and retaining the airtight seal when switching to tubeless.
