I have a 2011 F150 Lariat with a 6.5' box. I have goodyear tires (275 65R 18) and they are wearing down fast. I need to replace before Winter. I have shopped extensively and I think I am more confused than ever. I am leaning towards the Toyo Open Country AT (285 65R 18) or the Mickey Thompson ATZ (305 65R 18). Does anyone out there have any suggestions as to what tire I should go with? I do mostly highway driving with some off-roading. I do pull a trailer in the summer, along with a quad. I do want a tire a little larger to fill in the wheel-well. The stock tires have always looked funny on the truck. I am looking for any advice from fellow Ford owners. Thanks.
