These tubes may be heavy but they are very strong. I ride only desert single track with lots of big sharp rocks and cactus and no flats yet. I'm a big guy 250+ pounds and I only run 12psi with these and no pinch flats.
Both front and rear seem to be a excellent tire. I haven't had the tires long enough to rate the tire life. The cornering is jjust as good as Anakee 2. The only down side tomthese tires are the noise. The mid range from about 30 to 60 is quite loud, doesn't have any vibration. Looking forward to evaluate the mileage. Great dualsport tire.
After some really bad luck with 2 Metzeler 888 rear tires that cracked after about 1,000 miles on each. I switched to this tire. It is a lot smoother ride and seems to hold the road way better in the corners. I know everyone says that. But really this time it's true. The Metzeler 888 rear tires are just to hard of a compound and slip on the slightest of moisture on the asphalt. A little scary on a corner. When the rear slips out a foot then grabs it scars you pretty good. I give this tire 5 stars on everything. But I did on the Metzeler 888 also, wish they had been a better tire after all the money I spent on them. Metzler did return my money on each tire after a two month wait on each tire. Live and learn. Ride free, feel the wind, breath fresh air, be safe.
These tires are great! Just put on my second set... won't put anything else on my bike. Handling is awesome, great wear both during day-to-day riding and on the long haul.
First set of stock tires only got about 9K before needed to be replaced... got almost 20K off my MCII.
