So this is kinda funny. I run these tires on my sled trailer:
Loadstar 5.70x8 C/6PR @ 75PSI. The tire says "High Speed" on it, but there is not a speed rating identifier anywhere on the tire. The only other info is the DOT #, which is 2QA4 Y08, but that doesn't translate directly to how DOT numbering works on LT and other auto tires...
So I called the manufacturer and asked them to define "High Speed". The answer was they test at 65MPH, but if properly inflated higher speeds are no issue. I said sure but highway speeds out west are 75+, and I've hit 85mph w/ these once or twice. Am I at risk for blowout etc? "No, you should be fine".
That is not exactly the warm & fuzzy I was expecting to get....
