Two possible causes to this ^ reported issue:
1) The tires are too big for the rim. (If you run a 305/70/17, or better on an XE or O.R. rim, without any squirm, then the size is cool). So I'd really like to hear from people running BFG AT KO 315/70/17 or 35x12.5x17 ATs, as an example.
2) Maybe the posts I found are from people not used to a MT tire, and even if they got wider aftermarket rims, they would have reported Tire Squirm. So, any of you with MTs on wider aftermarket rims experience this? I guess even stock diameter mudders could have this if it's a tread design reaction.
I'm thinking to put on 34" diameter 305/70/17 Maxxis MT-762 Bighorns, on my stock Off Road Pkg. rims. (17x7.5). But, I found these posts that make me wonder about the cause of their tire squirm:
This member had the 34" Maxxis Bighorns.

This one had the Goodyear MT/Rs also in a 305/70/17:

Not sure what your thread is about, but I ran BFG A/T
315's on the factory 17" O/R alloy wheels, no problems at all...What do you mean by "squrim"?

The two post that I linked to, are talking about unstableness, and both were running 305/70/17s, one a Maxxis Bighorn, (I'm considering these), and the other a MTR. These were on the OR rims. I figured it was probably the tread, but in the Maxxis thread someone suggested it might be due to the tire size on the OR. Since your 315s were stable, it definitely sounds like the tread lug size was their issue.

OK...I'm running 295's on the same wheels now, still no issues...

I'm also considering the Toyo MT in the 33.5" diameter 295/70/17, but the Bighorns are a lot less expensive, sound like they are great in the snow, and take very little weight to balance them. The other thing is the Toyos in the 295s weigh 75 lbs, while the Bighorns in the 34" diameter 305s only weigh 65 lbs.

Of course if I went with the Nitto Terra Grappler AT, their LT295/70R17 weighs only 55 lbs each and their LT305/70R17 weigh 61 lbs each.

I'm hoping that with 34s, I don't end up with the torque converter non lock-up issues that you experienced with the 34.5" diameter 315s.
