Can anyone tell me what causes cupping on the inside of a tire? I've had it aligned and all is within specs. The noise it makes drives me nuts on a two hour commute....

How often do you rotate your tires? With new tires you should rotate them early on to prevent your tires from making that noise.

There are numerous web sites with tire wear information.

Maybe this is of some help.

I rotate them about every 5k. This is the second time I've rotated since June of this year. Do you think thats enough?

That's not too bad. Usually on a brand new set of tires i'll rotate them around 2-3k miles. But 5k isn't terrible. Most people don't ever rotate their tires anyway. Did you have both a front and rear alignment? Cupping is usually caused by the vehicle's toe being out of spec.

Yes I did. I'm thinking of bringing it in again for an alignment. But I have a feeling it could be the wheel bearings. :surprise:

2nd gen Charger in need of new wheel bearings? Unlikely... Unless you have a lot of miles on your car. Usually wheel bearings will give you an indication when they're in need of replacement. They will make a noise ("woo woo woo woo") when turning one way or the other.

I'm creeping up on 50K miles. And I do have that woo woo woo woo sound constantly. But the sound doens't change when turning. It kind of sounds like a helicopter. And to be honest, I've had the noise since about 30K or so and purchased new tires hoping it would go away and it did for the most part, but now is returning....

Did you have the alignment done with the new tires on the car? How recently was the alignment done?

No I haven't done the alignment with the new ones. I had it done in May about 2000 mi before purchasing the new set. I have a 36k alignment so I will bring it in and have her checked and go from there...

That could very well be the problem right there. You should always purchase new tires before getting an alignment done if you're getting close to the end of the tires' life.
