So, can someone help me understand these tire ratings?
I have, what appear to be, "P" tires on my FX4, that came from factory. I see that lots of people are trading up to an LT tire, which I guess is supposed to provide more plys which makes the tires sturdier and less prone to puncture or have a blow out? (Am on the right page so far?) So I am looking at the LT version of the very tire that I have now, the H/K AT-M's, in the same size, etc, Tread pattern, side lugs, etc, are all identical. I see that the even though the LT tire has a "C" load rating, it appears to be about 200 lbs less load capable than the load rating of the "SL" Standard Load tire. 2469 pounds on P "SL" tire, and only 2270 pounds on the LT "C" tire. Plus the LT tire is about 7 pounds heavier per tire (which affects MPG's). It would seem to me that solely based on the maximum load rating, the P tire would be better, no? What am I not understanding?
