Well ...that is good to know. We have our rig at the dealer and addressed this issue with them and they 'said' they would be contacting Heartland regarding this issue and get back to me. I also sent an email to the manufacture guy here on the forum and asked the very same question. We feel we need to know this and I will push the issue due to the fact this is a serious safety issue. Thank you for getting back to me. Maybe this is something that needs to be address with Heartland. The manufacturer should be liable to recall these tires if they are failing rather quickly out on the road and causing potential serious incidents. I work for the government and know people in the highway safety community and if this is not addressed, this could be taken up with the State Department of Consumer Affairs. If we could get enough folks coming forward, this could push for a mandated a safety recall, maybe!. We love the Heartland product and it is a beautiful rig, but this tire thing is what the rig is dependant on and should not be an additional cost that the consumer should bear right after purchasing and spending 40K.
