Question about factory wheel offset and tire size after 2.5" RC li

[BigMikeVA]

I've been searching on here and google and cant seem to find any solid answers. Just ordered a 2014 Silverado with 18" wheels.

1.) What is the factory wheel offset? Someone posted it was +18mm for the 20 in wheels. So is it the same between the different size rims? (Also curious if GM posts these specs anywhere)

2.) Looking to put on the 2.5" RC lift and new wheels and tires. RC site says you can fit 285/70R17, 295/65R18 would be 2/5in taller and wider. So most likely no problem with rubbing?

3.) Also looking at the XD Rockstar 2 wheels. 18in they only offer 0mm offset, 20in they offer with 18mm offset. Changing to 20 in wheels is an option, but looks to be about $500 more than a set of tires and 18" wheels. So would there be no chance of making the 18in 0mm offset wheels work besides wheel spacers, which I've heard nothing but bad about.

 

Also whats your opinion on the Rockstar 2 wheels? I know I used to see the original Rockstar wheels everywhere, but havent seen any of the Rockstar 2s yet. Or any recommendations for black wheels without any chrome? It's a black truck, and color matching the bumpers, grille, mirrors and handles as soon as I get it.

 

Thanks guys

I believe it is about +31 or so i know my 2007's was. I have the 3.5 inch rough country with mayhem assasins with a -12 offset running a 285/65/18. I did not have to trim anything and never has it rubbed even turning very sharply.
