My old tubeless tires were getting a bit ragged so I picked up a set of 700x28 ones that were a bit more than 28 and rubbed the bike frame. So while I waited for some 700x25 to arrive, I put on some Maxxis Detonators on a set of older rims and rode with them. Two flats in 2 rides. Gaahh!!! Then I remembered why I ride tubeless.
It takes me about 5 minutes to change a flat. I carry 3 tubes typically. Pull one bead loose and flip it over to inspect the inner surface, pull the tube. Put in a new one, pump it up and go.
FWIW. I align the tire labels so that they don't match up with the valve stem. It drives the roadies nuts on group rides.
