So I tried less air today, dropped it to 32, then all the way to 28PSI. I tried the chalk trick, which works great, I now have contact across entire tread. At speed, I notice less bouncy potential which it had at 37PSI. It seems to track straighter, have less potential for wandering, bu the drift due to wind or road angle has increased, to me thats normal for big tires. It actually feels smooth right up to 65. At 65 you start to feel more of the road, then at 71-72 I get a slight vibration/buzz in the steering wheel, this is a new one, which was not there at higher pressures. Another mild vibration/buzz at 76-80 in the steering wheel, and less vibration in the wheel above 80 but still there. No real vibration noticed in floor or from the front other than wheel. The vibration in the wheel in my opinion will rip the front apart in 20-30,000 miles.
I tend to agree, the vibes are all over the place, depends on temp of tires now as well, Ill get them back and rebalanced. 35" BFG MK2, AEV Pintler wheels.
I have the same wheel/tire setup and have a balance issue with them around 55. Actually it's just one of them and I feel it when I rotate it to the front end. I've rebalanced them several times, tried static and dynamic. I have seen several posts where AEV recommends balancing them using "fingers" in the bolt holes of the wheel, rather than the cone through the center cap that everyone does. I'm going to ask them to try this next time I bring them in. The shop said they always have complaints about balance with the AEV wheels.
OK, round two, they did use a Hunter balance machine, but found it was broken, so they rebalanced with a BFH 1000, using LAZERS. It does ride smoother now, no vibes till 72mph at 36PSI. Then less vibes than before but still light steering wheel and light seat of the pants vibes. Still think it's KM2's? I've had those on a Bronco and no vibes other than obvious road buzz caused by road surface changes. All lift components double checked for torque. No steering issues. So other than vibes above 71-72mph, it's smooth now.
Well, you're on the right track if the condition moved to another speed range. If you have a well balanced, matching spare I'd swap it in one wheel at a time and pin down the trouble maker(s). I'd still be looking for a shop with a Hunter Road Force balancer. Might try their search link here: http://www.gsp9700.com/search/findgsp9700.cfm
I'm more inclined to blame the KM2s. FWIW, I had two sets of them on mine, 35s and 37s, and thought they were marginal at best. First time I've ever dissed a BFG off road model tire. Both sets were noisy and hard to balance, and frankly weren't all that good on the trail. Worse, size-wise they aren't what they are marked. The 35s were really 33s, and the 37s were 35s. Plus, they aren't 12" wide, they 11". Because of the amount of wheeling we do here I got a set of 37" GY MTR/Ks and love 'em.

TMI IMO. To each his own I say...

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
AEV pintler wheel , 35 KM2, and using Gorrilla wheel lugs and locks, why do you ask about lugnuts? I'm not noticing any excess noise with the KM'2, but I had 33 KM 1's I guess what you call them in 33's on a previous jeep, same sound, not bad by me.
Are you saying we might have an AEV wheel problem? Can tire balancer pic that out?
