I only ask because I already have my rim running tubeless. Last winter I ran it with a tube, but I’m being lazy and not wanting to switch it back to have to use a tube. It’s a really tight fit.
I’m concerned because the tire spec says minimum 100 PSI inflation and I really don’t want to blow this thing off the rim at 100+ PSI.
You used to be able to get away with hacking a tubeless setup with low-pressure mountain bike tires 20 years ago, before tires and rims were made specifically for tubeless use.
Road tubeless systems run higher pressures and rely on a bead 1) that doesn’t stretch at all and 2) is made to tighter diameter tolerances than regular clincher folding tires. If the tire doesn’t say “tubeless” or “tubeless ready” - use a tube.
