Video of a soapy water leak test on a brand new Continental Mountain King II tubeless tire with the Protection (tubeless-ready) sidewall.
There's soap bubbles on the sidewall but the dense, pure white dots scattered over the sidewall are small leaks that Stan's tire sealant can't seal.
Note that after I wipe the bubbles off that the little white leak bubbles reappear pretty quickly.
