Slight shimmy at 55 to 65

I just got new 31 inch general AT2's put on my jeep and now it has a slight wobble at high way speeds unless i accelerate passed 65. Pep boys put the tires on the stock steel rims, balanced them and did an alignment. Now I took the jeep back today to get them balanced again to see if this solves the problem. After driving home the wobble is still there and he is assuring me that they are balanced and if i have anymore wobbles it is not because of my tires. Should i go to another shop to see if they are actually balanced good or should i be checking other suspension components?

Get them rebalanced and watch over the guys shoulder. Close is not close enough.

I'd go to a different shop then. I have some guys down the street with a Hunter machine who have no problem with me watching over their shoulder. There have to be more shops like that. Either that our you have to raise hell with them in the waiting room that they have to be exact. They are too prone to take the easy way out.

Make sure you are not over inflated, as many tire shops tend to do. Make sure toe in is good. And as noted above, perfect balance.
Do a dry steer test and check all the tie rod ends up front, check your ball joints and unit bearings. Both ends of track bar. Control arm bushings too.

With the engine off have someone turn the steering wheel back and forth a few inchs while you watch the steering linkage and the parts attached to it.
Your looking for slop where it shouldn't be...

Listen to biffgnar. It's a balance issue. I had a shimmy between 45-50 mph. The tire shop I bought my 35's from balanced them 3 times before I took it somewhere else to get it done right.

It's a tire balance problem no matter what that shop is claiming.

When you have a choice, buy American made.

Listen to what you're being told here and don't listen to what PB is telling you.
Speed related wobbles, shakes, and shimmies are almost always tire related.
In your case it started after doing nothing more than getting new tires, that makes it even more likely.
Take them to a shop with a road force machine and have them balanced properly.
Then, (after you drive it and see that the problem is gone) take the receipt for that back to PB and tell them you want the money back that they charged you for "balancing" them.

Ask them to rotate front to back, and take it for a test drive. If it goes away or changes, tell them to rebalance the back ones.
I would mark the tires to verify they actually rotated them.

You'll probably be better off in the 26-28psic range.

28 cold would be a good starting point, pressure increases as the tires warm up from driving.

What did the tire shop set them to?
