Unless you have the owner's manual for your King of the Road 5th wheel trailer you will need to look on the trailer frame for any indication as to what the weight capacity is. You can also check the length of your axles for any weight rating that they might have as well as that is often stamped into the axle. If you are having trouble with that, then you can find out the weight of your trailer by taking it to a commercial scale like what you would find at a truck stop.

As for new tires, if you can let me know what the size of your tires are, like the Castle Rock ST235/80R16 Radial Trailer Tire #LHACK133.

I can make a recommendation for a replacement for you. The size will be located on the sidewall of the tire and will look like ST235/80R16.
