Please straighten me out if I'm misunderstanding. I'm 3300 miles away from home  |
Dual application is side by side duals, not dual/tandem axles. The tires on your trailer are rated for 2540. If you have 4000 lb. axles (2x4000=8000 lb. axle rating) - you need to double check that; I would have a problem with a trailer with 8000lb axle capacity and a gvw of 8800 - EVERYTHING needs to be going your way or you will be overloading the axles.. 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
