I have a 83 K5 with 6.2 diesel, 350 auto, Np203 parttime and 4.10 gears, will this be ok with 35 goodyear wrangler MTR, if not what gearing? lot of higway and snow driving. Live in Norway.
And what tire pressure should I use?

Thanks.
 
Ya have to factor in the plant.
For a gas popper I would say that 4:10's would be ok.
For a deisel I would go with 4:56.
PSI for snow depends on how deep and what not
For me if it looks like it is gonna be nasty I throw iron.
 
<font color=blue> 4:10 should be o.k., but 4:56's would be that much better !
 
I'm running the 35" goodyears with a 350 and 3.73 gears. It isn't the best, but I can certainly live with it. But, my tranny also makes it "liveable". I'm not worried about swapping gears any time soon, because I don't mind having to lug it a lil more, but really, I haven't noticed much of a difference over 33s. It's awesome! See my website if you are interested in pics with those tires.

i have 4.56s turning my 35s... works well for me. I have OD so I have some flexibility with gears.... prolly go up to 4.88s at some point when I run 37s on street and 39.5s off-road...

I have 3.73s with my diesel and do fine but I wanna step up to 4.56s to get a little more power. I think 4.10s would be good since you dont have overdrive
 
Thanks for all help.
What tire pressure do you use on highway with 35" ?
 
Since you have the 6.2 diesel and the TH350 trans (no overdrive), I would not go any lower than the current 4.10 gears if you spend a lot of time driving at highway speeds.
 
I have 33x12.5x15 BFG M/T's on 15x8 steel wheels. I run 5 under recommended to get a little better ride. I drive on the interstate a lot and they have lasted me near 30,000 miles now. They show no signs of cupping or unusual wear.
 
The tire you get will have the correct PSI on it for the street, I believe mine is 35
Offroad I go down to about 15
Make sure you take air with you, driving on the road back home with that pressure (15psi) is a deathwish
 
When you got a "diesel different" type question go to the Diesel Forum.

I run 4.56 with an 700R OD (for now) and BFG 35x12.50. It gets real RPM limited to not have an OD on the highway. If you like to go 65+MPH (?KPH) alot stick with 4.10s. 6.2s don't like lots of revs, the CDRV can't keep up and you'll end up replacing front/rear main seals all the time. Had my D60/14B had 4.10s instead of 4.56 I would be stuffing a SM465 under the floorboards right now, instead of saving up for an NV4500 w/OD.
 
Thanks for all help. No OD isn't a problem here inn south Norway , the gouvernment here have some strange ideas so max speed limit is 55 mph on highway. want to keep revs low because 1 litre diesel cost ab. 1 dollar and gasoline cost 1.2 dollar, thats almost 4 dollar for 1gallon.
