Have a 5th wheel Astoria Platinum, less then 500 miles on tires 1st blowout 65mph on fairly hot summer day on major interstate, 2nd blowout at 45mph 67* out, all tires recommended 80psi. Not fun for a 72 yr old guy changing tires due to 2hr service wait. Why would you cheap out and put these Chinese Bombs on to save a few bucks. Needless to say upgraded to a major brand load rang F for a thousand $. Would have gladly paid a few bucks more for better tires instead of dealing with all the hassle. Wake up use better tires instead of cheaping out, probably lost my business next time around
