Rear tyre wear

[GertTurdInside]

Hi guys, I have a 4 door gti and since day one I have had problems with my rear tyres wearing on the inside. I have had the "toe in/out" adjusted and eventually it seems to go back to how it was and the tyre wears again. I have read on here that the shocks can be the cause, if so why would that effect the toe in? Surely shocks only allow movement up and down? Don't want to shell out for new shocks and find I'm in the same situation after a few months. Any ideas?
Thanks

Is it wearing the tread away or what they call saw toothing. Uneven to the hand when you run it over. If so there are two large figure eight bushes that go from rear of hub towards centre of car attached to the chassis. They wear and when they do cause this effect. Also apparently the car was set up to aid in grip with rear wheel camber so they will wear the inside first, however not by much and not enough to scrub the tyre before the rear of the tread is worn down. They are about £80 from VW for both and sorted the problem in mine last year.

Hi, It's wearing smooth, to the point where I have to change them every mot! They look fine from the outer side not even on the wear markers. I have checked bushes but nothing sprang out as worn. I know there's only so much you can see externally. Any suggestions where to go from here? Thanks for the help

Has to be a tracking issue?.

Had the tracking done 3 times.

Worn shocks can wear tyres. You could always have the shocks tested for faults

I'm intrigued...can you explain how???
On another note i suggest that you try bring your  car to a proper alignment specialist as it must be a camber issue in order to excessively wear the inside of the tyres..

For rear tyre wear for the fault quoted that's VW take on it!

They say the shocker isn't strong enough to force the tyre to maintain contact with the road resulting in flats being formed on the tyres.

As above as the shock fails it reduced contact etc etc. Had it once years ago on a friends punto. Completely scrubbed the inside of the tyre. Turned out the shock had failed. Replaced and a new tyre and all was good. If the tracking is right and you say it's been done three times it lends itself to be a failed or worn part

Thanks for the replies guys, so just to clarify I have had the wheel alignment done using a "hawkeye" system which apparently is the most accurate system out there. After about 6 months you can see both the wheels has moved and kick out causing the scrubbing on the inside. It's smooth wear not the saw tooth that other people have described.

My money is on worn rear shocks.

Had the same thing on my first MK5 (Jetta) and after replacing the rear bushes and having the tracking done 3 times i replaced the rear shocks and no more tyre wear
