BTW, tires do little. LT tires will stiffen the side walls of the tire so that the handling is better. BUT standard P tires have more than enough capacity for the truck. Most larger P tires are rated for 2500 to 2600 lbs. X4 = 10,000 lbs!!! More than enough tire capacity out of a P-tire.
According to fed regs ;
"When a passenger car tire is installed on a multipurpose passenger vehicle, truck, bus, or trailer, the tire's load rating shall be reduced by dividing by 1.10 before calculating the sum (i.e., the sum of the load ratings of the tires on each axle, when the tires' load carrying capacity at the recommended tire cold inflation pressure is reduced by dividing by 1.10, must be appropriate for the GAWR)."
Doing the math show the P tire still has enough capacity but not as much reserve.
