What do you do when you have a flat tire ? I don't have any experience changing tire or repairing inner tube. A long way from home, in the middle of nowhere, under the summer sun, what if I have a flat tire, sometimes I ask myself this and the thought of flat tire is freaking me out. Am I worry too much ? I want to go tubeless but not sure that it's safe or not. Do tenere rims have safety beads ?
