Hello.

I have a 2003 B6 Avant 2.4 V6 petrol. For a while now I keep getting this problem on both rear tyres. It only effects the inner walls of the tyres and is noticable by a 'thuding' noise whilst driving. I had the tyres replaced and it happened again. Then I replaced the rear shocks and had a 4 wheel alignment done as well as tyre replacement again. Having done around 10k the rear tyres are really bad again. I really don't know what is causing this and the cost of tyre replacement is high. I did notice though that the rear of the car is lower compared to the front of the car (top of wheel to wheel arch).
Please help if you have any ideas?
The only thing I could think of replacing now is the rear springs.
Many Thanks
Steve

 

It's weird because i've been experiencing the same thing, just not as drastic. I always hear thumping and I can never decide where it is actually coming from. I was assuming all new rims/tires and a 4 wheel alignment would fix this, but from reading this, I dont think it will completely fix it.

 

I know. Rear shocks or wheel alignment seems the most obvious solution, but in my case this has not solved the issue. This is the 3rd set of tyres on the back and each time I am getting around 10k before I notice the issue. Of course, being front wheel drive, the rear tyres should last ages!

My only thought at the moment, is whether some of the rubber joints that connect the rear axle to the chassis may be seized or corroded and preventing the rear suspension from moving with the road surface.

It's like the tyre is skipping along the road which should be prevented by the rear shocks.

It's a mystery!!!

 

As you mentioned, the rear of my car also seems lower as well. The wheel gap is much smaller than in the front. Hopefully someone can chime in for some tips!
