I have the 37"x13.5"x22" Toyo M/T's and before that I had the Nitto Terra grapplers. I thought the Nitto's were loud until I got the Toyo M/T's..They definitely are very loud. However, I wouldn't trade them for all the tea in China..I love the look, plus if it starts to bother me, I just turn the tunes up louder..Da BRUTE
