a buddy of mine owns a carlot and got traded in an 04 dmax yesterday. i went and rode in it today and it has nitto mud grapplers on it. them are the loudest damn tires ive ever heard! at 70 they sound like a 2 stroke dirtbike! just thought i would put this out there in case anyone was thinking bout buying a set. with the windows up and radio turned up you could still hear em plain and clear.
