Is that 3000 lbs per tire a estimate or actual scaled weight ?
Rv trailers with slide outs are notorious for weighing several hundred lbs different side to side...plus running in a strong side wind all day long can over load a tire on the down wind side if it doesn't have any reserve capacity. Tire experts say a 15-20 percent reserve capacity is a better idea.
What is the trailers GVWR ?
Does your trailer have 6k or 7k axles ?
Lots of 16" trailer wheels rated for G tires (3750 lb ) at 110 psi. Check your wheels for proper load and pressure rating.
Not sure what the actual trailer (cedar creek) GVWR is, but it is about 14,000 pounds. Our trailer weighs 15,000 pounds, each axle is about 3000 pounds, and the pin weight is about 3000 pounds.
We were at the FROG raley last year and had the trailer weighed by individual scales. Very accurate. Our tires are rated at 3400 pounds, but apparently the tires fail under 3400 pounds.
We have 6000 # axles, which is a design mistake on Forest River's part. A 5th wheel this size should have 7,000 # axles. Going to 7,000 axles and higher rated tires, wheels, etc,would be very expensive.
thanks for asking.
