It's time to get new tires, but I don't care for the stock ATs that came with my truck- a 2017 2500HD with the L5P Dmax, Ext Cab & long box. I found a few tires with better tread depth, but I'd have to mount them to 16" wheels. My stock wheels are 17 x 7.5" My questions are:

Will a 16" wheel fit on my 2017 without interference with calipers, tie rod ends or ball joints? And, does anyone have an opinion on running 285s in lieu of my stock 265s? Yes, I realize the aspect ratio may change as will the tire diameter- however, the data I'm seeing suggests there will be less than 5% additional tire height. It would appear that I've got clearance up front for the extra 2" diameter.

Of larger concern are the 16" wheels. And, will any of the aftermarket programmers (EFI Live or whatever) allow me to change the tire diameter in the PCM's code? Any comments would be appreciated. Thanks!
