i looked hard at the bighorns because they are suppose to be very tough tires. i decided against them though because of their weight. instead i purchased itp xtr radials. very nice tires. i have had them on for a year and just returned from the paiute trail. my only complaint is that while fooling around on oem tires, you can easily kick the rear end out on corners. the xtrs get such great traction that the initial tendency is to go up on 2 wheels instead of sliding. it is more driving style than anything else but with oem tires, i could just sit there and slide all over the place. no flats or leaks and they dig in well under the conditions i ride, trails, rocks, mud, snow, sand.
