I have 7k axles with 8 lug wheels.
I don't understand how having 7k axles matters. It just means they can handle that much weight correct? It doesn't mean the tires also have to handle that much weight does it?
That is, as long as I am only carrying 5.5k on each axle, the tires on that axle also only need to be able to carry 5.5k correct?
Or what am I missing?
Your not missing a thing.
There is no law that says you have to use a 3500 lb rated tire on 7k axles. Road side dot is the only law you need to be worried with. A LT E with 3042 lbs capacity will satisfy them and your 2750 lb per tire requirement. The LT E will give you a nice reserve.
I some times up size my equipment trailers axles when I purchase one new. I've upgraded to 7k axles for the bigger brakes several times when buying a new trailer (non RV). That way I can use LT235/85-16 E on those trailers.
I have never seen a recommendation for the General Grabber or the Dunlop Rover or the Bridgestone R265-5 rib or the R-500 for trailer use. However as long as the tire isn't a AT or MT type tread they may work.
Tire on the time of first retail sale are required to be "S10.3 The tires on each motor home and RV trailer at first retail sale must be the same size as the tire size on the labeling ...".
Now your free to use any tire you choose as long as it has the capacity for the load.
