Found a nail in my 37" KO2.. Not real happy about it either....
Had the same thing happen last month while I got hurt at work. Guys wanted to do a load and go to the hospital in the truck. Found the nail and started to hear the hissing. Got into another truck and off to the hospital.
Came back home to find my truck with the spare on. Had to replace the K02 that didn't have a warranty. New tires mounted with warranty added as well as the other three and about half a grand later my truck was whole again.
A month later after X-rays, (6) dr visits, an MRI and surgery to repair my ruptured and fully separated Achilles later, I'm sort of whole again. Just 4/9 months to go to walking, running and jumping again. [emoji849]
