Worn front tyres...

[renault12ts]

...excessive wear on the inside edge, especially on the offside tyre. What's the problem?

could be camber and tracking Needs a good laser set up by a competant place Just tracking isnt good enough The whole suspension set up needs checking. When I had my Brand new mx5 the caster, camber and tracking were all over the place. The car was actually crabbing !!!!! Mazda dealer said it was fine. The people in Melton showed me the comp print out. Seems all late model mx5's are as bad.

The problem is it's a W210, they all do it regardless of how they are set up. All of my previous 210's did it and I had them all set up at great expense with four wheel alignment at an MB dealer.

I used carnetix in melton They are brilliant

Those tyres look like the camber might be out and the pressures might be a bit low given ample use of the power steering.
Both insides and outsides are worn and there doesn't appear to be any feathering so tracking probably isn't the cause.
Longer life tyres may help.

I usually run the tyres at about 35 psi.

Though the near side tyre has more inner wear than outside, its not significant. The off side tyre is the bad one. Would a new cranked camber bolt fix this?

Possibly. It's strange how the O/s tyre has more general wear.

How old are your front springs and were they specified to take the Martian plate...

The springs were both replaced in April 2009, about 3 months after the tyres were replaced. And were the correct ones for both the engine and the plate!

Both tyres were also from the same batch.

I'm finding that a good indie accident repair place that knows MB have better alignment toys than a tyre fitter. They commonly have to do 4-wheel alignment and know what's what with an MB. Not all of them can do this.

Unusual to see that wear on the outside tyre. But normally the inside tyre takes extra wear on its left edge due to roundabout syndrome, that may be compensating.

Tyre precious on S210 be 29psi/30psi for light use. But do see inside your filler cat flap. Raising pressure can increase wear, possibly causing the tyre to roll the tread rather than keeping it flat on the deck.

Get camber and castor measured on all four as well as toe in/out fore and aft. All are adjustable to some degree.

are these tyres now illegal or are they still OK, since the inside part (so much % of the tread) is still well within the legal limits.

my front tyres are similar to this. car had 4 wheel laser alignment 1 year ago and new tyres at the same time. i assume mine needed higher pressure...

anyway, will the tyres be illegal now?

cheers

 

[renault12ts]

Very much illegal. The os one anyway, especially since it is through to the next layer!!

The picture would indicate that both edges of both tyres have worn leaving the centre of the tyre ok. That would indicate low tyre pressure although you say you are running at 36psi, how accurate is your tyre gauge?
