Your tires have probably dry rotted, living in a dry desert, it’s not surprising. Look for cracking on the sidewalls or let some air out and squeeze the sidewalls. Guessing you will see cracks.
If you don’t want flats, get a touring tire. Schwalbe Marathon Plus. Not the best riding, but you won’t be on the side of the road changing flats. https://m.youtube.com/watch?v=aqaFrdQjQEo -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
