Strange Tyre Wear on 2003 E/W211 with Goodyear Eagle 245/45/17 95W MO

[waggers]

Guys, looking to see if anyone has had issues with tyre wear on W211 with Goodyear 245/45/17 MO (8.5Jx17 OEM alloys).

OSR tyre worn on inner edge but one third of it has inverted quarter wear down to canvas, other three quarter looks OK. Tyre has travelled approx 30K miles but tread wear on flat is still good at around 3mm and no real wearworn on inner edge to suggest alignment issues. On replacing this one I asked for fronts to be checked for balance and NSF has worn the same. This has done around 21K miles and again tyre wear is even across tyre width and no wear on edge, tread depth around 3.5 mm across whole tyre.

I've been doing high miles and motorway speeds.I was wondering if tyre was wearing at the extreme edge but it doesnt appear to be and if tyre has got hot and then melted/malformed to cause this issue only on one part of the tyre?

Any ideas. Attached picture of rear tyre edge, but same on front.

Looks to me as though it may be rubbing on the bodywork?

Low tyre pressures will cause this fault, so check them on a regular basis. The front lower ball joints tend to wear alot and also I am replacing many torque strut bushes that are worn out. These two suspension itens can cause starnge tyre wear so get them checked.

I bow to BlackC55's specialist knowledge so deffo do as he says and get the suspension items checked out.
If that tyre came off my car I'd load it up and crawl under (use a pit or perhaps 2 offside wheels up on a high kerb), looking for something on the front and rear suspension rubbing.
I've never seen anything like that before, but I always keep my tyre pressures up. I would have otherwise said that something must be contacting the tyres whilst they're rolling.
I would also be looking for shiny marks on the suspension legs etc. Camber issues due to collapsing joints, as Black seems to be saying?

That tyre does seem to be rubbing on something to cause the deep track around the tyre, the only thing that would be in its path in that area would be the strut spring lower housing..have you checked for a broken spring..

Thanks guys.

BTW: I'm not complaining about the tyre mileages. It was a statement of fact - ****** good all things considered, it was just the way in which it has worn that appeared odd. I would have expected the waer pattern to be even around whole circumference not limited to around a third.

Things I've done:

1. Tyre pressures checked every two weeks - running at 30PSI front/32PSI rear - per label behind fuel filler cap - is that right for 245/45 OEM tyres?

Q'n can anyone advise what tyre pressures they're running at for 245/45/17 on W211?


2. Did check bodywork at that's what it looked like - nothing shiny, all clear, nothing rubbing

3. Front ball joints changed last year - resulting in 4-wheel alignment by Mercedes Sept last year.

4. Returned from Merc yesterday - All shocks and springs, bushes all fine.

Rear alignment wrong and both front camber/caster wrong. They told me that last time the rear was adjusted first and then the front. Then added re-adjustment of the front caused rear to be out. Weird thing is I've not hit anything or dropped in a pothole or run over anyone/anything. What they have done is added additional bolts to the suspension alignment points. Apparently from factory there's one bolt, they've now added two and re-set the car up. We'll see how it goes!

Thanks again

Hopefully youve taken the offending tyre off as it is dangerous!

 

[waggers]

Yes, three tyres changed...

 

[waggers]

yes, all sorted - it needs a 4-wheel alignment and camber angles adjusting. All tyre pressures, suspension parts , tye pressure ALL OK. It's the geometry set-up....

best guys I found who know about this and sorted it first time are Wheels in
Motion - speak with Tony (the boss). He's also done my BMW 330D H/top
Convertible with same issue!
