ok k30, turbo 400, np 208, dana 60, 14 bolt with detroit and 4.56 gears. it would be a daily driver with some wheeling and towing. don't want a lift. 9.00Rx16, which is 36.1" x 9.8" can be mounted on a 16" Wheel. 11.00Rx16 which is 38.7" x 10.9" can be mounted on a 16" Wheel i don't mind running the 36s. i just don't want to over-rev on the highway cause this will see daily highway. the 38s would be cool for the big tire look and to get some more space under the diffs. i'm just not sure if a diesel can keep up with 39s and 4.56s for towing and general dragging stuff around duty. what do you think.
