What would you do?

Ok, I'm running 6.5" Rock Krawler coils and custom long arms on my
'88 MJ Comanche long bed. NO FRONT FENDERS, just tubes.

The bed will be trimmed up quite a bit and the wheel wells should be roomy.
I'll running running normal 15x8 Crager steel wheels:

I have an open Dana 30 front with 297x shafts
and a 31 spline Ford 8.8 rear welded both with 4.10s.
I have an auto trans with a healthy 4.0.

I run Ohio trails, ruts, mud and some woods rocks.

WHAT TIRES WOULD YOU RUN:

TSL LTB Swampers - 34x10.50x15 for $122 each
TSL bias Swampers - 36x12.50x15 for $170 each
Maxxis Buckshot or Big Horns 35x12.50x15 for $135 each

I can't decide.

the maxxis bighorns

The Swampers are unbeliveable in the kind of terrain you are talking about. I think you should go with those. Everybody says they are crappy on the road however I like the noise they make and I can still hear my radio just fine.

only reason i wouldnt go swampers, thats a heavy 36in tire on a stock d30, so my choice wasnt what tire i think is better but what tire is better for his setup. now with some shafts i can see it but still 36s and a d30 is pushin it

Will 36s fit with 6.5" of lift and no fenders? Yea, those 34 LTBs are sweet and cheap... I won't be on the road much at all. I think the 34s will be too small.
I'm leaning toward either the 36 TSLs or the 35 Big Horns.

36s will def fit, i have 6.5 in and trimmed fenders and could easily fit 36-38s with proper bumpstops
