So, camp-n, are you saying that if it's an available OEM option it's still not "stock" if you drive that vehicle off the lot? My little ol' F150 XLT has the optional 20" wheels from Ford, so isn't that still a 'stock' truck in sense of the term?
By what you are saying, anything over a white, vinyl floor covered truck with roll up windows and manual door locks is "stock"... Which is what I call a "base" truck.. All of my trucks ratings is based on how it left the assembly line, and that was with the optional 20" wheels.
Just going from what the manufacturer website states. Ford shows 17s as standard across all trim lines, 18s and 20s are optional. Couldn't find anything regarding an option for 20s on GMs site.
Yes you can get larger rims on upgraded trim levels and special edition models but at what cost? (and I'm not talking $$) Those models all have lower ratings. Show me where that's not in part due to rim/tire size. You want a truck with the highest payload and tow ratings? They come with smaller rims, not 22s.
