I don't use tubeless and have only used the Marathon Supreme 2 sets and now the Mondial. No flats in 5 years. I weigh 318 and use the 26" D x 2" W tires. Mostly road and hard pack. 40psi front 55 psi rear. I live in the high dessert. There has been very little crap in the road until recently. I am know seeing large amounts of glass busted up on the shoulders of our roads. I bought the Mondial this time for a longer lasting tire.
