To anyone who was wanting to know for sure! They do fit. First I tried them On the OEM chrome 17x8's. They did fit, however, they rubbed when I was about half way turned.
I wend with 17x9 motometal wheels with bigger offset, They rubbed on extreme turn, I had to turn the wheel 100% to get rub. I melted the wheel liners back a little and now no rub at all.

So you can get 315's to fit at stock height. Infact I am getting ready to install some rear 2" Drop shackles.

 

For you guys with '06+ trucks, the clearance is bit tighter than '02-'05 models, so you will need to choose more backspaced wheels and/or trim a bit more...
