I ran those pepboys definity MTs (31x10.5) until about 6 months ago. They lasted a good while. I DD my jeep and they were great on-road, quiet, great in the snow, no problems in the rain (but remember these are MTs) and they were great off road and no problems in the mud. I used to drive circles in the mud and snow around my buddy's 4.0 equipped with BFG ATs (31s), they would cake up and slick over on him throughout the trails, while my Pepboys kept me goin. I was actually looking to continue with them in a 33x11.5 (or as close a size as they had to that) but they were out of stock so i went with teh Toyos. Overall, the Pepboys 31s are a good buy.
