Well it is a 2005, no tire certification label, just a GVWR label inside a cabinet above the sink.
It came from the factory with the 235/85-16E’s per the build sheet I got from Keystone after purchase used.
This is a fact you should be aware of tire/payload sticker was not required until 2006.
The abuse an LT tire takes on a TV is far worse than it takes on a trailer. Many blame instances of curb scuffing, potholes, and hitting bad RR crossings for blowouts on ST tires, while I try to avoid these I don’t worry when it does happen.
As to weight capacity, seeing how my LTs have a 3,042# capacity good to 106 mph, I would believe that at 65 to 70 mph they are capable of supporting more than that at the lower speeds. I don’t expect them to support any more than their rated 3,042#, in fact they are only supporting 82% of that when fully loaded with 10,000# on the two axles.
