Thanks for the input on my previos post about saggin springs. I just got back from a 700 mile road trip with my new springs and am pretty excited to throw them on the truck.

I have a J-4800 SOA with 2" over stock-arch springs on them. I am curious as to what size tires I can/should run. I am kinda new to the 4wd scene so I appreciate the help.

1. Is there a good way to figure out max tire size that will fit given the above info?

2. Is there some way to calculate max tire size? (Based on lift height, and tire width)

3. I realize that fitting the tire in the wheel well is only part of the problem. I have a D20 with 2.03 LR gear ratio, and axles with 4.10 gear ratio. I am looking for reliability, I don't want to be out in the middle of the Alaskan bush and tear something up. I don't do any crazy wheelin, just slow steady driving though snow, swamp, and the occasional river. Any thoughts about tire size vs. gearing would be appreciated.

4. Due to the type of driving I would like to do I am leaning to the "pizza cutter" style tire. Something relativly narrow 9"+/- and as tall as possible as opposed to tall and wide. If you dig deep enough you can always find something solid/frozen under the surface mush up here.

:D Please throw opinions my way.

5. As soon as I graduate I plan on heading to SW somewhere, AZ perhaps. Will the above mentioned tire (narrow and tall) work well in the environment found down there?

I know this is a lot of quesitons. If I need to start seperate threads let me know please. Thanks for the help everyone

I would say your gears are fine for a 33x9.50 on an 8" rim....since you like the 'pizza cutters'....even a 10.50 would work...IMHO... ;)

The 33X9.50's will be just fine. I wore out 2 sets in Southern AZ and had no problems with them.
:cool:

Pete, my 72 J-4000 is set up identical to yours but w/o the 2" lift but my springs are in great shape and I'm running 33x9.5's and really happy with them. I think they'd work great where you live.
