Damage to tyre - any ideas?

When checking the tread depth on my tyres I was shocked to see this damage which appears to run to the carcass of the tyre. It's the inner part of the nearside front so easily missed. Luckily it's about time to replace my tyres but apart from a possible flat spot due to an emergency brake on the Isle of Sky I don't remember any other damage. Wheels have had 2, 4 wheel alignments set ups as well.

Any thoughts?





 
As Jamie said,

You have geometery issues, possible bushes need replacement too, but needs to be checked either way.
 
Had two 4 wheel hunter alignments done during the lifetime of the tyre Jamie :(

Must say I wasn't happy with the handling of the Zed after the first one so that's why it was done again at another (forum recommended) garage. I suspect the alignment was out due to the first set up BUT I still think there's some damage been done as there is a flat spot where the wear begins.

The damage only runs half way around the tyre as well . . . :?
 
Did you get a print out from the garage?

Have you ever replaced you rear wishbone bushes?

What is the tyre on the otherside like?
 
Which tyre brand is the tyre.Is the tyre rubbing on full lock causing the wear.Lucky you spotted before a blow out.
 
My car needed replacement lollipop bushes when I bought it at 70k, worn ones will alter the track of the wheels and give uneven wear-I'd get them checked out soon.
Regards
 
Fairly common on Z4 tyres to wear much faster on the inside even if the alignment is spot on.

That's simply a massively overused tyre and should have been checked sooner. Dangerous and totally illegal of course..

When you say 'damage only runs half way around the tread', in reality do you mean the tyre is worn out all around and no cords showing on the other side?
Flat spots and brake problems can cause more wear on one part of a tyre than others.
 
Lucky fella with the recent amount of spirited hoonage you've been doing , could easily have ended in a blow out :cry:
Is it possible they were the tyres fitted before the last alignment as often once a tyre heads off with uneven wear it will follow that pattern
 
Had exactly the same wear on my 19'' tyres, due to excessive negative cambers on tne rear. When I say excessive, it was actually within the parameters allowed as I had a hunter wheel alignment done. It was just a lot more than it would be as standard.

Nothing to worry about, just bin the tyre and get a new one sorted.
 
Steph reminded me that we hit a steel base plate at a filling station on that side front - it's possible that knocked out the alignment. Had the 4 wheel alignment done twice since though.

Despite checking the tyres regularly for tread depth, as I knew we were near replacement, I did miss this wear on the inside - oh yes the last couple of hoons might have been a little fraught :cry:

Only saw it when I took the wheel off to replace a side bulb - I was a little shocked to say the least especially as the rest of the tyre was wearing uniformally.

Had front bushes replaced just before the AUC warranty ran out about a year ago - I'll ask my Independent to check the rear.

Not overly concerned - winters on now and new summer rubber going on for next season. Recent 4 wheel alignment done so I put it down to a flat spot and/or damage causing the wear - Zed's handling since the last set up has been fine (though I'm going to ask for a slightly more aggressive set up the next time I have it done - would like a little more turn in).

Zed in for the MOT just after Christmas - needing rear discs and pads and will have my Inde check for anything else.

Thanks all :thumbsup:
 
Looks like excess negative camber on the front. The rear tyres on the ///M will do that on standard settings. I keep a real close eye on mine these days after I found something similar a few sets ago. :roll:
 
I've seen a failure like that before on another car - can't remember the maker now but it was an a good tyre to that state in a 500 mile time scale .
The cause was a failed bush on a rear tie rod.
