Can I possibly have a defected wheel/wheels?

To start off I have 22x11 Fuel Hostages with 37x13.5x22 Toyo MT's. I have had the wheels balanced twice since the tires got put on the new wheels. I still have what seems like a vibration. When I had the wheels balanced the 2nd time, the shop told me there was up and down movement in them. When I first put the lift and 22x14 wheels with these same tires and if I remember correctly the truck didn't ride as bad. It's almost as the wheels/tires have a hop to them, not so much a vibration. It basicaly feels like I'm riding on Mud Grapplers, but without the noise. The steering wheel doesn't move very much. Is it possible that one of the wheels have the bolt pattern drilled off center some? The shop balancing also said one wheels had a lot more up and down than the rest. When the first shop balanced them hey did a horrible job. Between 55-65 the my arms were shaking while holding the wheel.



There's a local shop that install lifts often and also mounts and balances large offroad tires on a regular basis. I haven't brought the truck to them due to having time to get it there. They're a very busy shop. I just want to get others thoughts before I bring it.

Are the wheels hubcentric? if they are not then the lug nuts is what centers the wheel and they may be off a bit. The lug nuts are designed to hold the wheel on the suspension. the center hub is what locates/centers the wheel on the truck. You should have the wheel shop where you got the wheels order you the spacers you need to make the wheels hubcentric if they have not done that. if the wheels are hubcentric then make sure they are not over torquing the lug nuts. That could cause problems also.

I forgot to mention that I originally had 65 psi on tires to keep the low tire pressure alarm from going off. I dropped to 55 psi and got better but still not perfect. Would dropping to 45 psi solve this issue. In simple term the truck feels like I'm riding on rocks and not asphalt.

I think if you drop your PSI too much you will end up getting a under inflated tire wear pattern. i think a lot of it has to do with the big 22 inch wheel. More metal further and further out from the hub of the truck makes for a interesting ride.
What i would do is have the wheels checked for a out of round condition. I would also call the manufacturer and see if they can give you a idea. Most wheel manufacturers will stand behind their product and if they are defective they will replace them.

On my previous truck ( 07 F-150) I had 37x13.5x22 Kumhos and ran low 30's psi. I figured with a diesel 45 would be fine, but I'm no expert.

I don't think it's the tired bc they didn't ride as they do now when I had them in the 22x14 wheels. On those wheels they had less side wall due to being stretched so they should ride even better. I've been really busy this week, but hope to let sone air out by the weekend and hive it a try. The only other thing I can see is the wheels being out of round.
