315/75/16s on stock

I have searched and most of the info I found was either to vague for my need, or wasn't for what I was looking at doing. I was wondering if 315/75/16s will fit with stock suspension. I know the rear will clear, but the front I'm wanting to know what is necessary to clear them. I know that the bumper will have to be trimmed/shimmed to fit, and i have read that most tires that size rub at full lock for us without a decent size lift or spacers.

Also I was wanting to know what the maximum I can lift before having to modify my drive shafts? I read that I can shim my carrier bearing, but to how far? and what about the front? I would like to go with a 4" lift, nothing too crazy. I am planning on doing a dana 60 swap in the near future.

*The reason I'm asking this is my tires are getting rather bald and I have enought to get the 35s, and not enough just yet for lifts. I figure I would spend a little more money on the 35s and not upsize later

I'm running 305 70 16's had to shim the front bumper but a 315 is 1.5" larger depending on tire brand.

I have not seen it done without a leveling kit.

I believe you will not have issues with a 4" lift as far as drive lines are concerned.

On a 350 you will rub lock to lock but bumper should be fine as long as its perfectly straight. On a 250 it will rub lock to lock and you will be cutting the bumper by at least an inch

I have 315 75 16's on a F250 with D60 under it while running 16x10 wheels - there is no room for anything bigger but I do not rub. I had the same tire and wheel set up on the same F250 while I had add a leafs instead of the D60 and it rubbed pretty bad on the back side of the fender. Hope this helps, good luck.
