This product failed causing the tire to burst and the tire was also damaged and needs to be replaced. The inner tube burst and while I was driving my double car it blew a hole in a tire and nearly the next one but luckily it broke before that happened. When this happened I was towing a 40 foot fifth wheel across the country and luckily I didn't have a single rear wheel or it could have killed me and/or others. Leave $25 for an extension and spend $500 for a tire change!
