    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.

    FWIW

    I have a M1008 and could not fit 305/85/R16 buckshot mudders without some fender trimming or lift. These measure about 36x10.

    If you want to highway cruising above 60-65mph the 36's will rev a little on the high side for the 6.2 IMO

    I run 39.5's with 4.56's and the 6.2 in my K5. Even with 40's it's still pretty 'buzzy' on the highway (~2500 rpm @65 mph).

    I'd lift it a little, trim a little and run the 38's...

    The 6.2L diesel rolling on 4:56 cogs would probably like Q78 x 16 Super Swampers TSL’s as they are 35.5 inches tall and tastefully narrow for my kind of wheeling anyway. The 6.2 will still sound like the pistons are swapping holes at highway speeds but it will still be trail friendly as well. Q78’s are slightly taller and wider than the old school military 9:00 x 16’s and will still fit factory wheels nicely. (Q78’s are an old school tire size too but still cool). I am not a big fan of the metric “P” tires…..305/85/R16, 305/70R16, 315/75R16. etc for my kind of wheeling. I am just not into the rock video rock crawlers nor am I looking to inflate an my ego or win a rock crawling trophy with a dune buggy on steriods either. I just like to be able to get to the nice mountain lakes to catch some fish that most people wouldn’t dare trying to reach.

    I have Q78’s mounted on 6.5-inch wide elcheapo wheels on my rig with only a 4-inch lift and ORD shackles. No hacked out fenders, no rubbing under full flex on the trail…..nothing. I am sold on Super Swampers TSL’s for what I do. Check it out my rig with 4” & Q78’s & and here is my old tow truck with arched springs and 9:00 x 16’s for comparison. The 9:00 x 16’s look pretty small.
