Review on SCHWALBE Pro One TT Time Trial and Triathlon Tubeless Folding Bike Tire - Enhance Performance with Evolution Line, Addix Race, Multiple Sizes, Black/Tan by Brandon Grzankowski

I noticed that one of my two tires lost air overnight despite installing it correctly and using sealant. It turns out that the tire is riddled with small holes at the bead and sidewall, through which air constantly flows. Be careful and check the tires for leaks immediately after mounting. As I said, my front tire has no problems and works great, it usually needs a little pumping up after a couple of weeks but I've read that this is normal with tubeless tyres. Revain replaces the failed tire.
