wheel and tire question?

[texastrendz]

what i have is a 72 long wheel base with a stock with rear end for this year. i ordered my wheels. they are 17 x8 with 4.5 backspace for the front and 17x9 with 5.00 bach space for the rear. my question is are they going to tuck up in the fenders front and rear? truck has air ride suspension on it. what size tire would you guys run since i am going to have plenty of room veritcaly i hope. any help would be great
