My 2015 Silverado had the RHA bilsteins on the highest notch and barely, I mean barely rubbed with 33x12.5x20 Toyo at 2s. Got this 2016 2500hd and put a cognito level kit on it with bilsteins all around and 295/60/20 (33.9x11.6) and don't rub at all. Some one told me the 2500s wheel well is slightly bigger than the 1500s, but I dunno if it's correct or not, look into it, you could possibly fit a 34. Also, the toyos ride smoothe, are pretty quiet, and still look aggressive. Buddy of mine got 75k out of them Sent from my SM-G955U using Tapatalk
