Tires: Difference between a P245 and an LT285, 9 rims, abs units

Question
Is there a difference in how a P245/75R16 (manufacturer recommended) and an LT285/75R16 will handle on a Chevy 1/2 ton?

Answer
Frank,

A P245/75R16 has a load carrying capacity of 2065# at 35 psi after being derated 10% because of its use on a pickup truck.  It has an overall diameter of 30.5", a width of 9.8" on a 7" rim and fits on 6½" to 8" rims.

An LT285/75R16 has a load carrying capacity of 2755# at 50 psi (Load Range C), but at 35 psi in has a load carrying capacity of 2130#.  It has an overall diameter of 32.8", a width of 11.3" on an 8" rim, and fits on 7½" to 9" rims.

So there are situations where the LT285/75R16 can not be used because of the size of the rim and the physical dimensions.  Plus the LT285/75R16 is 7% larger in diameter and some ABS units do not respond well to such a large difference.

Plus, it would make the vehicle sit about an 1½" taller, which is the wrong direction for vehicle stability.

Directionally, this change would also mean worse rolling resistance, wet traction, snow traction, ride harshness, and steering response, but many of these properties are more closely tied to the exact tire and not size, so careful selection might reverse this.  

I guess I really don't see an up side to this other than looks.
