The thought of tubeless has crossed my mind, and is part of why I opted for the A23 rims when I went with this wheel set. I am still not 100% convinced it is a good idea at the pressures I run, 55-65psi. I know that seems high in general for wide tires, but I still tip the scales over 200 and so it makes sense. Also, while I know some people have had success running the B-Line tubeless it is not really what it was designed for, nor the C-Line so I can not endorse the application. All that said it is still tempting, and I will let the pressure creep down on these and see where things go…
