I have 285/75/16 on my truck and there is lots of room even with the leaf springs up front. With coils you should be able to get 305 or 315's I would think. Clearance issues may come up with the bumper but I am sure there are people that have done this and will chime in.

'04 has leaf springs. My '03 had 315/75/16s on it when I got it, they rubbed at full lock. With the stock wheels you should be able to run 295/75/16s with no problems.

Talking 315/75r16

I have an 04 F250 FX4. If you put a 3 inch level kit up front and space the bumper out about 1/2" you can run 315/75R16 with out rubbing. That is what is on my truck. I have the Tuffy Country Leveler Kit with buddy shocks.

By going with 285, 305 or 315 are you not just going wider and not taller to fill in the wheel well? Isn't the 78 still the same height?

In a 315/75/16, width is 315mm, sidewall height is 75% tread width. So larger tread width numbers create taller sidewalls and a taller tire.
