I want to order some 18" coys... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So like the title states. I want to put on some 18" coys for my truck. Naturally I want the widest fattest tires a can. I've been searching and found 5" backspace for the back and 4.5 for the front is pretty common. Is this the absolute max before scrub line issues?
Also there's a lot of typos on the coys wheel site so I'm taking everything on there with a grain of salt. Would like to try some 255s up front and 275s in rear
I'm currently 6-8 drop but plan to go lower still with modular spindles up front and a pancaked crossmember with 1"taller lower ball joints. Should be good for 7-9 haha
