I've seen a few threads on this, but I'm starting a new one in case there's anyone like me that was looking for a quick answer. YES, LT285/70R17 will fit on the stock half ton suspension .. at least on mine it does! It's a 2016 Sierra 1500 regular cab base with 5.3, 3.42 and a snow plow prep option which means it has heavier front springs. Stock tires were 255/70R17 and the Ultra Maverick wheels I installed are the same as factory offset. Wheel wells stuffed! Sent from my SM-G973U using Tapatalk
