Not quite, tubulars are made for special rims, what I am dreaming of is a CONVENTIONAL tire made with a bead the clinches that ALSO has rubber along the bottom to make it very similar to a tubular but one that would still fit a common clincher rim. I understand how CURRENT tubeless tires work, but am wondering would this be a better solution than trying to make each spoke hole air tight and using sealant around the bead?
