those are about the same tires that we have on 5ton trucks. their spedo's go up to 65 and i was riding in one once when driver had spedo pegged so hard that when he let off gas and you felt 5ton NOTICABLY slow down it still stayed pegged for another good 15 sec. this on a windy country road with one of the crazyiest son-of-a-bithces i've ever known at the wheel...actually kissed the ground when that ride was over.
