I recently had uneven pavement/pothole damage. To make a long story short... I had to buy a new 166M wheel, a PS2 tire, had to balance all tires, and aligned the car. Now I have a brand new PS2 tire in the front but now I hear tramlining like there's no tomorrow. I never noticed this before.

According to the service dept., they said that everything (suspension) seemed fine. But then again, these service techs are not all knowledgeable. Foreman drove the car and inspected the car and said the same thing. They even went as far as replacing the new PS2 with another one to eliminate the possibility of a possible defective tire. When the new tire was replaced, the tramlining was not as bad but it's still present.

Has anyone experienced this? Could it be becuase I have a new PS2 with 3 old/used PS2's. Could I have damaged the contral arms or tie rods?

 

Really? No one has experienced this before? I am starting to feel pretty bad here...

 

I had two bent rims a while back, but extremely luckily, neither of the two tyres (PS2) were damaged in any way.
I had no problems with the ride once the rims were fixed.

 

Does it worsen or get better at different speeds?

 

It would make sense that you would have issues if one wheel is approximately 1/2 inch in diameter greater (due to wear) than the others.

In addition, the better grip of the new tire may always want to follow the grooves in the road (especially with the wider profile of these #166 wheels).

I always notice that my mileage is worse when I get new tires, and I think that it has to do with the greater friction of the new tires. You may be experiencing this issue with just one tire.

 

I notice it mostly between 80-85mph.

 

I thought about the diameter issue but the foreman says he highly doubts it. Also, I am not so much experiencing the tires wanting to follow the road, I just hear the ridiculous tire noise such as the sound you hear when the tire tramlines.

 

Spkoe to the foreman today and he's at a loss. He told me to give him a couple of days to talk with other service departments and the factory rep to see if they have any suggestions on what the problem could be.

 

You did not specify how many miles the other 3 tires have. If great enough I suspect that is your issue. Suggestions:
1) Put another new tire on the opposite front so you have all fresh rubber in front.

2) Put the new one on the rear so that again you have the same rubber wear on both front.


Your comment about "hearing" tramlining puzzeled me. I "feel" tramlining, but do not necessarily "hear" tramlining. What do you feel the steering wheel a or car doing?

 

The other 3 tires have 25k miles. I can't put the new one in the back because I haev bigger tires in the back.

The foreman said that the BMW rep had said that the fact that there is a new tire with 3 old ones could be the cause of my noise. But my concern is with the suspension. Does anyone think I could have possibly damaged something with the suspension? ie tie rods, wheel bearing, spindle etc.
