Gear Talk / schwalbe marathon supreme tires

« on: May 28, 2007, 02:40:05 pm »

so i'm planning on biking across the country this summer (first touring trip ever) with my dad. i've done all kinds of research and decided to go with 700x35 marathon supremes - thinking they're indestrutible and the greatest thing since sliced bread. this memorial day weekend, my roommate and i did a 280 mile, 2 day trip of the olympic peninsula (WA) and i flatted. it was a piece of glass, about 1/4" in size, that just penetrated right through the center of the tire. the shoulders on this route were extremely clean. i bike commute to work in seattle over glass and all kinds of crap using cheapo gatorskins. i've never once flatted as a result of a glass puncture (8000 miles?)

so now, my confidence is shaken. i don't want to be hauling 20 tubes or replacing them on a weekly basis on our trip. has anyone else had experience with these tires, and if so, good or bad?
