What is the best off road tire sizes for diesels. I mostly go off roading in the mud. I know diesels aren't the best for offroading in the mud because of their massivly overweight front ends. But from experiance does anyone have any comments on the size of tires and or lift I should get if I wanted to go out in it.

 

I can't comment on deep mud, but on mixed terrain mud/rocks the 255/85R16 do serve me well. Them being on the stock rims keeps them gentle on the wheel bearings and the rest of the front end, they aren't too high (truck doesn't want to go TU easily) and the BFG Mud Terrains offer good traction.

It depends on the kind of off-roading you do. There are some cases where you want a large wide tire that will "float" above muck.

Other time, you will want a taller, narrower tire that get's down to more solid stuff underneath.

Generally, I'd pick a wide "flotation" tire for mud, and a tall narrow tire for everything else, especially snow. A tall narrow tire is MUCH better in deep snow.

I'd run a 35" tire because you won't need much lift. You want to run the smallest amount of lift necessary. To me, the fact that you have to run 4" lift or larger makes stepping up to a 37" or bigger a waste. A 35" just needs some levelling, and you're set.

I agree with HOHN, but would add that a wider tire would also be much better in sand.

 

35s w/ 5 inches of lift will turn out bigger than you think...w/ 4.10s Im very happy...Ive only took my though a littleon rock pile once though.

 

How wide is mudding wide? 12.5 15 or like I saw on a truck today 35 x 18

 

I have been very happy with the 315/75R16 on out 97. Yes we have mud in AZ. It will eat any size truck you can put in it. We just have to drive into the lake to find it. There is one by PHX that goes up in the spring and down in the summer and there is bottomless mud in a few spots.

Also we have no lift. It rubs on the fender-well (the plastic behind the wheel) and the control arms. Also I trimmed the plastic on the bottom of the front bumper from about 1/2" to 0 at the top.

BTW, they are 12.4 inches.
