    305s are 12" wide as in 305mm. The largest recommended tire size on a stock silvy is 285/75R16 which equals to 32.9" tall and 11.2" wide. 295s are 11.7" wide You will clear the 33s in height with no problems the width is what i am uncertain of because your parts are different than mine. I would say max is probably 305. Congrats on the 14 bolt SF. I will be looking for one when my Grenade80's fuse goes off.

    You will be happier with 285/75R16. If you read the thread "Lift Questions" 05Z71 says he fits 33/12.5 on his 1500 with ford keys only.

    yup, I cant for the life of me remember what the backspace is on my wheels. guess I will have to look it up.

    Height wise your truck will handle a 33 better than mine, the frame is thicker/taller. The width is what will getcha

    I ran the 305/70r16 nitto terra grapplers on mine iwth just torsion crank, occasion rub but I think it had more to do with 10" wheels than the tire.
