Really, does that mean since you use all terrain tires that you should have bought a four wheel drive truck, lol? You have a lot of nerve telling me what I should have bought or schooling me on weight classes...it's rude. No offense, but I don't like 3/4 ton or four wheel drive trucks. They are too slow, too heavy and burn too much fuel. And I never said my tires increase my capacity or even hinted it, that's insulting. It increases safety and durability for my line of work and I can still play with it...that's it. However, I do beleive that it is unsafe to increase air presser above a tires limit to compensate for extra weight. Those of you who do, that's your business, I'm just expressing my opinion. I don't know all different types of tire loads and I don't care to. I prefer LT's with at least a D range for my work and that's it. And as I said relating to this topic, I never had any problems with Goodyear tires....LT or P rated. As far as your tires go, I never knew there was a C rated LT. None the less I wouldn't go less that a D range for my type of usage
