Get the LTs.P is just a car tire with truck type tread.When I buy tires for the Durango or the 04 Ram i always buy LTs.They are more but last.That and if you have any weight they are safer.Even in LTs there is a difference.Th Generals I bought for both of mine I looked at the weight also.I found The Gens were almost 48 pounds each.I found other tires in the same size and LTs that were only about 37 pounds.Rocky
