Go to the Heartland owners forum and type in Towmax tires and check out all the pictures of damage from blowouts with Towmax tires. They used to put them on all their trailers because they were so cheap. So many failures and threatened lawsuits and they now only put them on their lightest trailers. My tire dealer quit selling them because he had so many customers that came back angry from the damage from blowouts. Every once in a while I see someone that has had good luck with them but many many more that were very dissapointed. They're cheap for a reason.
