A tire sized P265/75R15 112S inflated at the 30 psi front and rear recommended for your suv has a load carrying capacity of 2,319 lbs.

A LT31x10.50R15 109S sized tire at 30 psi has a load carrying capacity of just 1,595 lbs - dangerously low as it reduces total load capacity for your truck by a staggering 2,900 pounds! Even at the maximum inflation pressure of 50 psi a tire of this size can only carry 2,270 lbs which is barely adequate - equivalent roughly to driving with the stock tires under-inflated by 2 psi. If you do buy the 31's you absolutely need to increase your inflation pressure to 50 psi or you could have a safety issue. Under-inflation not only causes premature tire wear but it can also cause the tire to overheat and fail.
