I have Hi-Run ST tires on our Prowler (dumped the BlowMax tires) and they came well recommended from the trailer builder that did axle work on our previous Heartland trailer.
We only have maybe 1200 miles on these tires, but so far so good!
We'll be giving them a workout in 5 weeks when we head down to Tucson, AZ to the HOC Rodeo Rally!
