If you rotated without balancing your wheels, that could explain the louder noise. Driving habits, terrain, camber and alignment all play a factor in wearing the tires down unevenly.

When you rotate unevenly worn tires without compensating for the uneven wear with balancing weights, this throws the balance off even more. Next time balance your wheels at the same time you rotate your tires.

Has your alignment been set? Rear tends to be toed out from the factory making for some loud front tires after rotating.

A lot of different factors can come into play with road noise after rotation, not just strictly alignment. Another post hit on several. When was the last time you rotated your tires? I have found on several different occasions that if you are rotating after 6k then tire noise is most likely to occur. Not saying it won't at 3k rotations, but every car that I have had to look at for tire noise the customer would only do a rotate here or there, and around the 10k mark.

What style of tire are you using? Asymmetric (tire has specific inside and outside tread, usually designated with the words "side facing out"), directional, designated with the word "rotation" and arrows? Or regular symmetric, with no change in tread? Having different styles can also designate the rotation pattern. I am pretty sure they say nowadays to rotate AWD in an x pattern. If you run directional tires you can only do front to back. Otherwise, you affect the water channelling ability of the tires.

When you rotate, you are really giving the tire a new contact pattern on the road. Being in one position, seeing only one point of suspension travel and just being in the same place will wear a tire to that corner. You can get noise simply from rotating because the tire is in a new position, contacting the road on parts that have not seen the same style of contact. The noise usually subsides within a few hundred miles.

As far as balance... Unless you have a vibration at particular speeds, it's really not needed. For a tire to wear from being unbalanced, it would have to be substantial and it would become annoying to the driver before it got to the point of really wearing tires.

Alignment is always good to check at least yearly. With gravity always pulling a car down and suspension wearing out at a given rate the geometry of a car can change slightly altering tire wear.

Sorry for the book, I would just rather see you informed then spend money when you shouldn't.

Thanks for the book. I don't mind a good read. This sheds alot of light on things. I've owned this car since new. Purchased in September 2011 with 75 miles on it. This will be the first time I've rotated the tires@10k miles. I know I drive alot that's why I haven't had time to rotate the tires. I expected to get more noise but this is like a bad wheel bearing. Redneck lullaby is what I call it. So I'm gonna wait a few hundred miles more before I have them check my alignment. Thanks for the awsome answer btw

yeah, I would put my money on the noise being lack of rotation. If you were to slide your hand back and fourth on the tire (pretend your hand is the road, mimic how the tire runs on the road) you would probably feel jagged edges and or hills or valleys on the outside edge. I have seen in severe instances that the wear is almost permanent.

these here are an example of where to feel, and what it may look like: This pic you can actually see where the tire contacted the road and where it didn't.



These are the tires that came on my car when I bought it (used) The previous owner I believe did no rotations. The car was so loud driving down the road.... it was horrible.



That should give you an idea. It looks worse in person... the pics do no justice.

Thanks again for your help dosman
That second tire looks pretty dam bad. I'm going to check my tires when I get out of work. On your experience does the noise subside after a few hundred miles of wear.... I should have rotated them earlier but life keeps me busy

Normally, yes. It does however depend on how bad it is. Those tires I have in my garage probably will never even out. It was that bad. I even broke them down and mounted them on the opposite side to try and help. *hopefully* you caught it in time. If anything try to keep it on schedule with your oil changes. I you change oil at 5k I'd do it with every one.

The recommendation for an alignment was because these cars are notorious for having bad alignment from the factory especially toe out in the rear. I agree waiting 10K is most likely the main reason for the noise but the stock tires are noisy.

I completely concur with you. I would recommend the alignment checked yearly, just to make sure. A competent tech can make sure to minimize tire wear and make sure you get the proper alignment needed to get the best life you can while having a straight driving car.

I recommend that a performance car gets a performance alignment immediately not only to correct flaws but to dial things in for your driving style.

out of curiosity, do you supply your own specs? or do you just go with what is supplied by the alignment machine? And by all means your recommendation is a solid one. For me, my plans with the car are on hold due to my current situation in life is up in the air, so I just aligned my car to minimize tire wear. I also needed to do it after replacing my front hubs and bearings as well as ball joints. The only thing I did not compensate for was being on springs, which dropped the ride hide just a little bit.

Subaru will pay for one courtesy alignment during your warranty period. If you're going to Sears, you might as well get it done free at your dealer.

I'll try the dealer. Free is my favorite price. Won't they only align the car to factory specs though.
I want more info on this performance alignment. What are the specs. I doubt that many alignment shops would know what I mean when I ask for that....

Yes. I also listen to what the tech suggests based on my needs.

Usually but they might be willing to do it to your specs it just takes more time. Factory spec has a wide range to it. Not good for precision.

It really depends on the tech and how rusty your car is...

It's to your exact specs usually a bit more camber than factory specs. It's best to go where the local trackday people go. Talk to your tech for suggestions.
