This tube is exactly what it is called "heavy duty" . I ride mostly PA mountains so rocks are on every trail. I run it at 13-14 psi and never had a problem with flats, only problem is the nut on the base of the valve stem isnt stainless steel so when changing time comes it will be rusty. But i never had a tube brand not come out rusty, and never caused a problem. Little thick to install but that is expected with the thicker rubber. Overall great buy!
