Ko2's will not balance!!!

I've balanced these things about 6 times in the last 2 months trying different places and 2 places used the road force machine. The behavior in the vibration at 70 changes every time they get re-balanced but is always there. The smoother the surface the more it shakes and shimmies. Almost feels like a drive line vibration but it's not. The only place I haven't tried yet is Toyota. Could they perhaps fix this problem? Also anyone else have issues with balancing the ko2's?

I have to say, all of my BFG tires never balanced well. They would in the beginning but would get progressively worse until they were a mess towards the end of their life. This made me start to look at other tires and I started to use Toyo. Since, I have had several ATII's and now I amusing the MT's. All have been outstanding with outstanding wear and they keep their balance.
 
It's the tires, the wheels, the installer, or all three.

This is why I buy tires from a brick and mortar store, that has a Hunter GSP 9700 balancer, and competent Techs that know how to use it. I also ask if they would allow me to use their machine to find a bad tire or wheel, if their Techs prove to not be competent to do so.

I've seen lots of incompetent Techs, wheels with excessive run-out, and tires with poor uniformity, over the years.

Could it be possible if I had a bad wheel? My brother has a taco with the same tires and is smooth.

First of all, is the POS Hunter coming up with zeros? If all 6 times they come up with balanced tire/wheel assemblies, your vibration is somewhere else.

2nd, if you put on new tires and they "couldn't" balance them, they have a real problem. I go to at least 3 or 4 tire shops everyday, and no matter how inexperienced or ignorant the tire guy is, they always seem to know how to get it to read Zero.

I've seen guys take a Chinese built 22" wheel with 37"x 14.5" tire, also Chinese and use 14oz of weight, but they always get them to balance.

I have to wonder about that too. There are a LOT of bushings on the front end of these trucks. I am pretty sure mine would benefit from new... EVERY bushing in the front end really. It drives nice but I know it could be better. I do however plan on new poly bushings throughout the front end just to tighten things up. Just because the alignment says its good, doesnt mean its PERFECT.
 
Anyway I'm just going to take it to Toyota tomorrow and talk to someone about my problem. I think the spacers are increasing the sensitivity to the truck. I know these trucks front ends are notoriously sensitive.
 
I'm running original KO's with spacers and before I got them everybody was telling me how bad they are to balance and how crappy they ride, none of my tires took any kind of excess weight to balance and they all ride like a dream, I've been vibration free for 10K now.
 
Airsoft pellets ... about 9 oz per tire should do the trick. If that doesn't work, then warranty the tires.
 
I've had numerous different brands of tires on my truck and never had problems until I got the Continentals I have on it now. They just wouldn't stay balanced and vibrated on the highway badly. Went to multiple places including the dealer until the tire shop agreed to change out a tire due to excessive runout on the tire (not wheel). It got better and there was another one that was borderline that they should have replaced. Tires are expensive and should have better quality control than they do. Most tires now have a 30 day ride guarantee so take them back and have them change them out.
 
Turns out one of my spacers hub ring was bent and causing the vibration. No clue how the ring itself just got warped? Anyways will replace and most likely will fix the issue
