Goodyear ATs versus MTs

I thought that my tire choices were settled until Discount called me this morning. I am going to get to test drive a set of Wrangler MTs for a week both on-road and off. They put the wrong tires on last night. I had never seen the Duramax ATs in person and the tires they installed looked a little agressive but it was late. They told me to come back at my convenience if I want the ATs. The tires sing a little but the ride is fine. The question I have is will the MTs ahve the same tread life and will they do as well on wet roads? If I had a 4x4 the decision would be a no-brainer especially since the MTs are probably $30 more / tire. The kevlar belts has me thinking about keeping them along with the fact that I do have limited slip and an electronic locker.

I run some pretty rugged country in central Tx so I thought the kevlar might be good.

 

well most muds don't last as long as an AT because of the less rubber to road ratio, basically the "longer" tread on a MT just wears down faster because theres a smaller amount of rubber hitting the ground on every revolution, thats how i see it, someone correct me if thats BS
