Tire can be balanced but still not be perfectly round.
 
If they were flat-spotted driving on them more doesn't fix that. I think you need new tires.

Are we talking flat spotted or out of round? There is a world of difference.
 
Flat Spotted= brakes were locked up and/or car slid sideways flattening out the tread in a particular part of the tire. Very rare on street cars, somewhat common on non-abs race/track cars. Usually this happens when you lockem up and spin or lock em up under hard braking going into a turn on the track.
 
Out of Round= tires sat for a long time under-inflated and therefore are now oblong shaped. This can also be a result of broken or hyperextended cables in the tires.

Yes. Still having the issue, but I haven't persued it any more. The vibration is feelable, but subtle. It annoys me sometimes, but I'm not sure it's worth the hassle for me.
 
It's not really a 'flat spot' but that's the easiest way to describe it. Tires are not completely uniform, and often they have a part of the sidewall or tread that is thicker or firmer than the other parts. Even if the tire is balanced, the firmer spot is felt when driving.
Increasing tire pressure does sometimes helps, as it essentially makes the whole tire firmer, and masks the problem. Of course, it will detract slightly from handling and ride quality.
 
Many dealers will have a Hunter road force balance machine to check this aspect of tire irregularity.

I have an '08 Tribeca with the same problems that were evident the first day I drove it. Here is what I had sent my dealer & Subaru after months of trying to get he problem addressed:

I still do not have any resolution but I did manage to get an extended warranty and a 45,000 mile maintenance agreement.

#24 of 39 Pressure/Ear Pain by sadie13

We recently purchased a 2008 tribeca and have had nothing but problems ever since in regards to ear congestion/ear pain. This pain is experienced whether we are driving or not. We have contacted Subaru of America as well as the dealership we purchased it from and have been told that they have never heard of this before. Has anyone else experienced this?

Adding to what my wife wrote. What we think the problem maybe is that we and several others have an allergie to the off gasing of the new plastics, glues, and vinyals. I am reaching out to see if anyone else who owns a subaru has had similar effects and if you did how long did it last. I have placed carbon filters in the vents and have had no releaf. I also purchased a $250. dollar air pureifiar specific to VOC'S. My family vehicle is now my work truck that I drive with the windows down with outside tempatures at around 35 degrees. Not sure whats worse freezing or a $30.000 dollar ear ace. My experience with subaru of America !#$%^&**#%^ lets just say I wil never buy a subaru ever again. My fist and LAST!!!!!!!!!!!!!!!!!

Wow, and you *both* have this problem? How quickly do the symptoms appear? Have you tried occupying another of the same make/model to see if the result is the same?

Yes, we have tried another new 08/09 and feel the same effects and the symptoms occur immediately for not only us but several other people we have had either sit or go for a ride in our vehicle.

We had what sounds like the same intermittent "shuddering" or vibration problem with our 2008 Tribeca. Our Subaru mechanic had us drive the car while he rode with us with his laptop connected to our Subaru. Basically, he captured some sort of readout while we reproduced the shudder. He sent this information to Subaru. Subaru told him that they knew about the problem and were working on a fix. Six months later, our mechanic received direction for the fix from Subaru. I will try to explain what they did, from looking at our service summary sheet.
 
I am not mechanically inclinded, so bear with me. It looks like they replaced the torque converter, the turbine speed sensor &/or o-ring. He also mentioned that he "re-flashed" it. I think he means a software update. These repairs were just performed yesterday, so only time will tell if it is the correct fix. If you require more specifics, our mechanic's name is Tim and he works for Schumacher Subaru in West Palm Beach, FL.
 
I hope this helps!

Now that a month and a half has passed, was wondering if the replacement of the torque converter, turbine speed sensor, and/or o-ring has correct the issue? I am having the same issue with my 2008 Tribeca.
