Cooper broke out the AT3 into 3 separate lines. You have AT3 4S (SUV/CUVs), AT3 LT (trucks), AT3 XLT (trucks/lifted). They’re all slightly different. The 275/70R17 is only available in the AT3 LT load range E right now. I emailed cooper a few weeks ago asking if they had any plans for a Load Range C but cooper says none in the plans right now. He did say this could change. I’ve been seriously looking at the AT3 LT in the E load range since it weighs 52 lbs. About 5-6 lbs less than the Falken Wildpeak AT3W in the same size. There is a huge thread over at Tacoma world for the new Cooper AT3 line.
