Oh no! not another wheel/ tire size thread

[maillet282]

I've been searching the forum for the last few days now. read a lot of various threads of what's the biggest tire I can fit on a stock suspension/ with a levelling kit and I've read conflicting information 

 

I guess I need to start by figuring out what came stock on my truck.  when I bought it, it came with 17" procomp wheels with 265/70/17 BGF all terrains ( looks like rugged trails) 

 

stock tire size I will look up on the truck in the morning  what I am looking for help is what are the dimensions of the stock rims that came on a 2017 Silverado 1500 LT True North Edition
