New tires

Oh yeah - another factor with the size choice is the spare fitting on the rear door. Any feedback from y'all with the larger tires on stock rims?

I don't know what you mean by larger size but the guys here running stock rims are using 255 and 265 70/75's and have no problems. With the widened steels you need one of the brackets that CWR sells to accomodate the wider rim. I am not aware of anyone running 285/75's on stock rims so have no available info on them.

I run 285/75R16's on stock rims at 50psi. My two 710m's are commercial 4x4 tour trucks so they spend thier life crawling around in the Colorado high country, loaded with people and gear. I have never had a bead brake free, even when side-hilling on talus slopes! I'm running Cooper mud terrains with great wear except for some chunking on the outside of the lugs.

Then you could tell him if the 285/75 on stock rims are a problem when mounted as a spare. I would not think it would be an issue just have never seen it done so could not say for sure. At 50psi or even 35 we have not had bead loss on stock rims, it is just when the pressure is lowered.

Oh yeah, the spare! Well it does fit on the back without any mods, but just barely. I have to carefully start each lug thread and as it tightens, the sidewall does compress against the rear door.
Curiously, one of my trucks has an easier time than the other with this, even though they are identical in every way.

I've had 285/75 BFG AT's on the stock rims of my 710 for about 2-1/2 years; running at 40 psi on the road and 18psi on the trails. Never broke a bead yet (I'm jinxed now!) and I've gone everywhere everyone else goes. Tire wear is really only on the outside edge, gently tapering towards the center. At this rate I'll dismount the tires and swap inside for outside in a year, and still get a few more years out of them (got about 15k miles on them now). They are certainly not mudders, but are decent in the rocks, sand, and pavement. I especially like them for their ice traction; deep snow is not too bad, either. In that area the are far and away better than MTR's on ice and hardpack snow.

What you want depends on what you want to do with them!

It looks like I'm down to the BFG or trXus in 235/85-R16. My thoughts on sticking with the stock size is to keep my gearing, unmodified chains, a little cheaper, ability to borrow/share spare tires with other Pinzies. I've NEVER wanted taller gearing on the trail, and wished it was half of what it already is from time to time. The taller gearing would come in handy from time to time on the road, but I'd probably take a hit on the long steep uphills - that I currently lose speed on. Do any of you mountain folks with the the taller tires lose more speed on the long, steep uphills than you did with the factory size?
Aside from treadwear, are their any other bitches about the trXus over the BFG? Mud/goo performance and, mostly, sidewall strength.
I'm getting 5 tires - I hate lame spares.
$700 for the 5 trXus
$800 for the BFG
Almost $1000 for the MT/R
$600 for the Maxxis Bighorn - I have not heard anything on these.
These are all delivered prices.
$ is somewhat of a concern. I don't want to pay a ridiculous premium for a tire that is marginally better - I'm not entering any competitions or going on an expedition. I, also, don't want to wind up with some POS that I regret wasting my time and $ on - that is my concern with the Bighorns.
Thanx again for everyone's input.

The share the spare thing is kind of funny. In a large group of Pinz trucks it is difficult to find two trucks running the same tire and size. The tire sizes while listed as the same differ from manufacturer to manufacturer. I also question problems with running two different size tires on an unlocked truck like the pinzquaer. With the ability to unlock the diffs while running different size tires on hard pack road conditions the truck should not experience any ill affects.
If you plan on using the unmodified stock chains on your truck I would find someone with the tire you are looking at and see if the chains fit. Just because the tire sizes are listed as equal does not always allow the chains to work. The chains are not all that difficult to modify anyway.
Jim M really brings up one of the best points you need to consider and that is your intended use. I find the BFG MT's to be noisier than the Trxus on the highway but the BFG's are more readily available (at least here).

The joys of owning such a capable truck.

The availability is not an issue. All the local shops that carry any of the better MTs in these sizes are way too $$ and still have to order them. Most of the prices were from eBay.
My concern with the gearing change is the single biggest reason for going with the smaller size. The rest of the reasons are just some perks I'm trying to convince myself of with going with this size (235).

5 x 255/85R16 for $780 delivered to my doorstep.
About a quarter cup of 2.5mm steel beads with enough peristaltic pump hose lube/oil to wet the beads (for rust resistance, I hope) in each tire for balancing.
These beads have been in my current tires for about 4 years. The couple of times I have opened the tire bead to get a look at them, they were in great shape.
Okay, no crap about being as indecisive as a woman

Thanx for all the input, believe it or not, it helped.

what did you get?

I wasn't very clear in my prev post. They should be here mid-week.

They sell the Maxxis Bighorns, also. Said they outsold the BFGs about 3 to 1. I'd imagine due to price - I didn't wanna risk it. I call around town for someone to price match - $156 out the door must be one hellufa price, everyone was crying that they could not even buy them for that price.
I'm kinda excited to see how much better the truck will look like without the deeply weatherchecked retreads on it.
Oh yeah, the 255s were $4 cheaper /tire than the 235s!

sounds like they handle factory "Blems" Great deal if you can get contact for them. Most of the time with the BFG tires it is in the BFG white printing. I would suspect that is why the local shops could not touch the price. I used to deal with a guy locally here that got them but alas he has moved onto other business ventures.
Now what is your next Pinz Mod.

Just put on Dunlop 285-75-16s Mud Rovers.
The first thing I noticed was that it was like I had put on power steering!
So much easier to turn when sitting or going very slow.
Don't have many miles on them but have been great in mud & I feel safer on the hiway w/them than I did the Maloyas.
Noise seems about the same to me.
Got them @ Discount Tire for $112 ea + $20 for Off Road Hazards.
