First thing you must do is weigh your rig. If it is within published specs, your load on the axles will be about 10,275 lbs, which is about 2570 lbs per wheel. Allowing for an unbalanced load, you should still be able to go with LT tires. I'm jealous, because our rig is much heavier, and we had to go with G614 tires, five tires, (counting the spare), were $1900. Still better than the cheap tires that were on our trailer.
