I believe C rated. Lighter tire, Stronger sidewall, better handling. I am not a tire specialist nor am I pretending to be, if you are one please do lead the way. I am always up to learning something new, seriously.
My truck will not see any extreme off-roading, in fact it'll spend 90% on paved roads. Why did I go with Toyos? Good reviews, good thread warranty, look aggressive enough without making my truck look like a tractor, price, made in Japan. My personal observations; handling is better than OE Good Year Wranglers (not squishy, running 33psi), slightly noisier, balanced really well, so far did really good in rain, hopefully will be as good in the snow.
