What are tubes? Some kind of antique thing? Yes I do carry one for backup. I run tubeless on all my bikes, commuter, fat, mountain and bikepacking. Get a tubeless rim and tire. Don't try to muck around on this point. I did get one 6 mm or so gash on a bikepacking trip, center of tread, front tire. Took out my curved needle with carpet thread, 3 stitches, super glue, waited for 10 minutes. Aired up just fine. Still using it 2 years later. Add sealant on a regular basis through the removable valve. Easy.
