I hope the axles are 5200lb. rating.
In your case, the calculation I would use is your gvw of 8800 and a total tire capacity of 10,160. In that case you have 1360 reserve capacity = 15% safety margin. Your weak spot, REAL weak spot, is if you have 4000 lb. axles....and if your tires are China bombs  |
More than 600# of the 8600# GVWR rides on the tow vehicle.
The standard reads, in part; the vehicle manufacturer's recommended tongue weight when added to the total vehicle GAWR must not be less than GVWR.
Tire load requirements for RV trailers are determined by the trailer's GAWR values, not the vehicle GVWR.
