On my 2015 4x4 Quad Cab w/ Pentastar , Mine were fairly even but I do rotate them at 5/6k . But I think my front tires had a little more wear ! My AT/S tires I have on now seem to be wearing the same ! I should notice them more then the SR/A's because of the larger lugs !
Good question TAZ , Now I will pay closer attention as you have my curiosity up lol
