rims!!!

i was searching the internet the other day for a set of wheels for my truck and i found a set like this for a decent price.i alreadyhave a set of old mag wheels that were givin to me for my truck but theyre to wide to tuck.what i was wondering is will these wheels tuck on my truck and does anyone know the backspcacing on them?

I have some 18" escalades for sale $300 plus shipping. U just need tires. Ill also throw in the grinded down hubs for the front.

i found a set like this for $100 within a 2 hour drive i put the ebay listing because it has more info than the other listing

i bought the wheels and took a trip to go pick them up they look like they will tuck alot so now ive got to sell my tires i just bought because theyre for 15 inch rims im asking 150 to cove the cost of a new clutch
