Tyres destroyed on inside wall

**Sumpy467** · 27-11-2009,10:44 PM

Hi, can anyone shed any light on this one?

My car is going through tyres every 6 mths (10k miles). Each time it's the inside wall which is de-laminating/wearing down to the breads, there's still a good 4+mm of tread left and they wear evenly. They are the 9 spoke RS4 alloys (but I suspect they are third party copies as the groove on the shoulder of the spoke doesn 't run down the length of the spoke. (?))

I've gone through 3 pairs on the front and a set on the rear. Each time I've had the tracking checked, and had 4 wheel alignment done last year: this was miles out originally. But very minor adjustments since.

I've tried differing the tyres pressures and avoiding the speed bumps on the way home (the square ones that don't cover the full width of road). I've had a good look round the suspension etc and found nothing untoward.

Has anyone got any suggestions, it's driving me crazy

Cheers.

Go some where else more competent for your alignment.

Mine was doing the same, 3 - 4 mm of tread over most of the tyre, then on the very inside edge was showing the cords!!!, i had a 4 wheel alignment done at the main audi dealership, £89 all in including any adjustments.

They found the toe was out on the fronts and also the camber angle on the left front wheel was out (this was also the one with the worse wear) its about 0.6 degrees out of limit, and they have put it down to either bent top ally arms or a bent hub carrier, not drastic as i can do both myself, but i am going to run it for a while and see how the tyres wear, afterall the toe angle was also a long way out.

Have yours checked again by a competent garage, my car also does a fair bit of tight manouvering, in and out of driveway, parking spaces etc, this could also have something to do with inside tyre wear.

Thanks for the replies.

I'm running Goodyear Eagle F1's 225 40R18. Used to have budget tyres but went for the Goodyears last time to see if it was just poor quality tyres.

(rhencullen1989) -Did the dealership actually find a fault with the top arm or hub? Sounds very similar to what I'm experiencing, having the alignment done on Tuesday with another set of fronts I'll ask them to check the arms and bushes etc. while its on the ramps.

I go to Apex in P'boro, after very good feedback. Plus I think its the only place here that can do 4 wheel alignment.

Cheers.

Strange this, that's the second time in a week someone has pre-empted the forum with an issue I'm having too.
My fronts had worn the outer corner of the tyre one inch or so. Totally bald, so I dropped it into ATS where they stuck a laser alignment jig on the front and announced it in spec. While we had the car on the ramp they showed me the inner edges worn to the threads. Not good.
These are Michelin Sport pilot II's and the pair on the front had been new on the back about a year ago and were moved to the front when I bought new 'front' tyres about 3 months ago. So most of their life (20k miles) they've been on the back. I initially changed that pair on the rear because the outer edge had gone bald, but didn't know the history of the tyres up to that point so wasn't sure where that wear had come from.

In the last week or so with the wet weather I've noticed that near full lock in car parks for example the car is literally skidding round corners - you can really hear and feel the car failing to keep the line. It just feels worse these days than it has before. On the open road it has no issues with handling/grip at all. I'm gonna drop it into my local Audi guys next week if only to make them reset the service clock which has been dropping a 100 miles (but still 419 days) from the next due date every time I turn the ignition key. Time to go fixed service intervals I think.

Mark.

Generally the Kwik fit type places can not do proper 4 wheel alignment. However apart from suspension specialists, a good quality crash repair centre should have the tools to check and alter wheel alignment.

Regardless of where you go it's important to receive a before and after printout and compare these to the spec for your car.

I have a a4 avant tdi sport which wore the front tyres off on the inside. About 30mm was down to the cords! Had 4 wheel alinement, all ok .MOT 'd all ok. Still a mystery

Just come back from having the 4 wheel alignment done. Not far off minor adjustment on front, otherwise spot on. Also had a look around for any damaged bits whilst on ramps, none found.

On the plus side the fitter is going to consult with goodyear rep, might get free replacement tyres so they can disect them and find any manufacturing fault. Watch this space!
