Normally I only run DOT knobbies, but I'm planning on a ride to Vegas from my home to my buddies home. It will include about 100 miles of pavement and I'm thinking of DOT tires for the ride. It is not going to be a trail ride, more just blasting down desert dirt roads. The total mileage will be near 700. I was thinking of getting something less aggressive like a Kenda K270 and just tossing it after the ride, but it would be nice to get a real knobby that might still get a little trail use after this trip. Has anyone tried one of the 110/100-18 Terraflex tires on a pig? I have seen plenty of reports on the older super wide 140/80-18 Terraflex. I have not seen much on the 110/100-18 size. Anyone used one? How does it compare with a D606 or other DOT knobbies?
