I used my tire on a 12" trailer tire that was used to tow my snowmobile. Accidentally left with the clamp in winter. I didn't realize it until I realized my tire was flat after driving 8 miles. The clamp broke the tire. The clamp appears to have fallen off after about a mile. I never found the clip again after that. A flat tire is not a sufficient deterrent for me. I tied the trailer to a tree with 1/2" hardened chain and everything is fine after that. I bought the grapple after my snowmobile and trailer were stolen from my front yard earlier this winter. Take care, good ones locks to be used Standard Lock Master!
