These used tires have about 25k on them. They were bought new and mounted on my one ton campervan. Just got a quote for a new set of these for $!,078 taxes in. They have been driven on a gravel road many times to get to our favourite camping spot on the west coast of the island so the treads look fairly chewed up even though they still have about half their life left. I have never had a flat with them but with such a heavy RV and for safety of the family have decided to upgrade.
