I need to buy new tires but cant decide which ones. I have narrowed it down to the nitto mudd grapplers 33x12.5x18 or the cooper discoverer stt tek3 LT275-70-18. I like both tires and i am about to order online just cant make the final pull on the trigger. the nittos are$304 and the coopers are 280 both are the cheapiest i found. I need some input from my fellow titan owners to make the choice. PLEASE HELP
