Does anyone else's tyres suffer from this?
https://www.oponeo.co.uk/tyre-article/saw-tooth-tyre-wear
I have the original bridgestones on, so was wondering if it's a common thing on other brands too?
-
Had it on my mk5 Golf. Became very noisy and sounded as if a rear wheel bearing had failed. You could see and feel the 'stepped' tread on the inside edge of the rear tyres. Tyres were Bridgestones.
Haven't experienced it on subsequent cars.
-
It happened on mk5 golfs due to wear in the rear suspension.
-
This keeps happening on my fronts only.
-
Thought I had it on the back but it was a dodgy wheel bearing. I rotate my wheels to keep the wear even, I think that helps.
-
With a few mm left and after ~60k my original rear OEM BS's finally drove me mad with this.
I can't complain really, ~60k is incredible really.
-
My P7s did it as well.
Now I swap fronts and backs diagonally every so many miles. Also wears them out evenly, so some hope the lease company then put on four of the same (well once they didn't).

That is, my P-Zeros are close on 18k and I think they would do 20 but I want to change them before winter regardless. They had a hard life for the first 1500 miles as a demo car judging by the test drive I had....

This is what drives me a little mad about golfs! My mk5 did it, my mk7 does it... What's the solution?

Tracking, not the VW tracking figures. Had it done on my CC's to stop it and never had a problem again, plus point was a nice little bit of lift off oversteer when i wanted a bit of fun. You will need to find someone that knows how to do it though, I have mine done in Birmingham.

Yeah makes sense, so they basically set the tracking up for you instead of following VW's tolerances/figures?
I'll have to find a decent tyre specialist not a Halford's autocentre :grin:

When I was getting the summer tyres on our other car - there was a GTI in front of me. He was getting 2 new tyres on because the inside of the tyres were bald. The staff told me that most of these cars have the same issue.
I certainly had problems with the Mk6 and uneven tyre wear.
Once my GTI has done a couple of thousand miles and the new suspension has bedded in - I'm going to look for a Hunter Hawkeye laser alignment on all 4 wheels.
-
I suspect that making wheel alignment changes outside of OEM spec will have some other sort of negative.
The OEM setup, like any setup, will be to achieve a set of performance parameters (handling, comfort, tyre wear, turning, braking etc). As with all such things, you can't have your cake and eat it. If you fix one thing, you'll unfix something else.
Its probably more likely some suspension component that has a wide manufacture tolerance on it.
Not everyone gets sawtooth do they?

VW and most other general car makers set their cars up for understeer hence the reason that a lot of cars suffer from rear inside edge ware. Changing the setting that to a more even steering and it does or at least did in my case introduce lift-off oversteer which can be fun when the conditions are right.
The Cup 2 below had covered around 15k miles on the back of my car, the right side is the inside.

Well, understeer is safer on the road for most drivers and if that results in rear inside edge wear, thats probably a decent trade off.
Having to replace my rears after 3 years instead of 3.5 years is a fair compromise vs spinning into a tree :)
I guess VW's legal department probably agree!

On the contrary the car handled better and oversteer could only be induced by lift off mid way through a bend so not exactly dangerous for anyone but the worst of drivers. Also the extra wear is not the worst part of the problem, the extra rough noise it generates is the most annoying part.
-
If you are VW's legal department then you assume that every customer is a moron... and probably apart from all of us F1 world championship winning drivers on this forum, everyone else probably is ;-) From their lawyer perspective, its cheaper for VW to prevent mid corner lift off spins by engineering.
PS I only got rid of my messed up ones because the noise was driving me mad :)
PPS I am the world's second best driver. My skill is so great that my modesty allows me to assume that possibly somewhere in the world there is one better driver. That's how good I am :-P

I think Lift off oversteer is considered more dangerous, ask the rental owners of Megane's at the Ring. Never a lack of people lifting mid corner and running out of space or talent. Throttle oversteer is different, to be celebrated and enjoyed, lift off is pointless in most cases on most hatchbacks. But as fredgroves says the legal dept probably got it right, with a few concessions.
PS what is wrong with your cup 2 in the pic, i couldn't see much?

Subtle tyre pressure changes will help with any saw tooth nonsense. It's usually failed suspension components and not alignment that's the issue.

There is nothing wrong with it at all, that was my point. With VW alignment specs it would have been destroyed in less than 10k miles but with the changes to the alignment it has even wear.

The thing with Cup 2's is they have bi compound tech so the inside edge is much harder that the outside. Where as most tyre companies don't do this, hence they can suffer from poor wear on the inside shoulder. Not saying that's the reason yours lasted so long, but did you run a set without Geo and cup 2 as a comparison?

Yes I did, they were taken off the front of a C4S and had covered about 2k miles on that but were still like new and within 8k miles the inside edge was feathered. That was when I took it to an independent tyre and wheel place who I only use now for everything tyre/tracking related.
-
C4S? I guess (should never do that) you mean the front of a 4WD 996 or 997 N rated? And put them on the back of your Golf after they covered 2k on the Porsche? Not exactly a direct comparison but I see where your going with it...

Yes and no, yes they were off the front of a C4S 997 but no they were not N rated.
