I just got the new Cooper Discoverer Rugged Treks in 285/70r17. They are a tiny bit
louder than stock size Terra Grapplers but can’t really tell unless you are paying attention to it. On the highway, the TRD exhaust drone and my radio drown out any road noise anyway. They are more of a hybrid AT/ MT with pretty
aggressive tread and sidewalls. I took them through some 1-2ft deep mud the other day and they handled it easily. Drive great so far on highway with good traction on rain/wet roads. Had to remove my front mud flaps due to rubbing though- even with the Westcott Designs TRD Pro lift installed.
