2013 wheel size?

[CoolRAMfU]

New to the RAM world, I'm wanting to get some wheels but can not find a definitive answer on the stock wheel size. I have heard 8in to 8.5 width and 10 to 19.05 offset and 77.8 to 87 hub bore. So whats, what? I have a 2013 1500 quad express 2wd.

Thanks for any help

Which wheels do you have? They differ.
