33X10.50 vs 33X12.50

[Mike S]

Doug,

I ran 31X10.50 MTRs for a couple years, and never wished for anything bigger with the stock gearing. The 33X12.50 is a lot of tire to push down the raod, and will likely overcome any theoretcial difference in 'rubber overdrive'. The longer footprint of a narrower tire will provide better stability on slick roads.

For 33's I think I'd go to 4.11 gears and 16" rims with 285/75/R16's with triple sidewalls.

I'm starting to think this is a perfect tire size for a lifted expedition oriented cruiser.

Let me know if you're going that way, Doug.

I am coming to Seattle on Weds., I think.

why do a thing like that sell brand new never used swampers befor noing if you like or dislike them ?

I bought them not realizing they were a bias ply tire and then put on the bfg's to run around town. Liked them so much, decided it wasn't worth the hassle to swap them out to go wheeling with--Utah doesn't have all that much mud...

OK, some folks are running 15x8's and some are running 15x10's...What is the main difference between the two rim widths? Im looking to get a set black steelies (rock crawlers), and the 15x8's are CHEAPER, but i dont know what effect that has on driveability. Right now I have 15x10's. Will 8's make ANY difference?
My rig is NOT a DD...The only road time it gets is driving to and from the trails, or when mine or my wifes car is down and im fixing them. I will be airing DOWN on some trails especially on my trip to death valley. Do any of you guys run SLIME etc in your tires?

skinnyer tire means you can air the tire down more and get a wider foot print . Because the rims holds the inside beads of the tir tihter due to the narrowness of the rim wich helps prevent busting the bead on your tire.most people running 12,50s are running them on a 8 inch rim for this purpose but it also depends on the type of wheeling you do maybe someone else can chime in?

So the 285/75/R16s are as tall as a 33", but since you have a 16" rim there is a little less sidewall and a little narrower footprint compared to a 12.50 on a 15" rim?
I'm planning on the Dakkar HD lift and regearing to 4:11s and I want to get a good tire/rim combo for this particular setup
I looked at the BFG A/Ts but couldn't tell if they had triple sidewall. What tire would you go with in that AT range?

All of the BFG AT's have 3 ply sidewalls.

All things being equal, 16" tires tend to have higher load ratings than 15" tires.

For expedition type use, taller/narrower tends to be more effective. For rock-crawling or deep mud, wider is better. Forget just now which is better for sand. For rain/snow/ice, narrow is better.
