Mercedes W205 rear tyres wore out after 5k miles

[Abela]

I had fitted 4 x Continental ContactSport 6 on my C Class W205 C250D last year August 27th 2020. Car is re-mapped to stage 1 and currently running at 250BHP.
265/30/19 on the rear side and 235/35/19 on the front side.
This week after doing around 5k miles, I found out that the rear tyres are already worn and need replacing very soon. Never did any burnouts.
The inner side of the rear tyres has maybe 0.5-1mm left. The outside has around 2-3mm left.
On the front side, tyres are still good however, they are also getting a bit weary from the inside than on the outside. But the front side issue is not that serious.
Please find attached the photo of one of the rear tyres.

Is this normal?

Sounds like the car needs full-geometry wheel alignment. Are there good places in Malta - preferably with a Hunter machine - to get this done?

...265/30/19 on the rear side and 235/35/19 on the front side...

BTW, as far as I know the W205 with 19" wheels should have 255/35 at the rear and 225/40 at the front (though I doubt it affects tyre wear).

Need replacing very soon ,I wouldn't drive mine with tyre's like that you definitely have an alignment issue ,i got more than that out of my old c63 (w204) and the tyre's I have on my w205 c63 are still like new after 5k miles

Hello and welcome .those tyres need replacing NOW . And there is something wrong with your car. If your car has 8.5 inch rims you should not really go wider than 255, but that is not what is causing this wear.

The car needs new tyres and a 4 wheel alignment done by someone who knows what he is doing . Best of luck . let us know what you find out

Those Continental Sport Contact 6 are well known for their very poor wear rate , combined with Malta's hot roads it's no wonder it looks like you've been doing some Bugibba burn outs !

Im gonna go with too many 1/4 miles at hal-far

Even when correctly aligned the rear wheels should have a little negative camber which will cause some uneven wear and the wider the tyre the worse it will be but it shouldn't be that much regardless of mileage. So it's not normal even with the very high wear rate of those Continental tyres. The type of use is a big factor and not just how much acceleration or wheel spin is used. I have 32,000 miles on my Michelin rear tyres but that is predominantly motorway use. I imagine it would be impossible to achieve anywhere near that on Malta.

Looks like chronic over-inflation to me. 5k out of a set of rears is bonkers, I changed the tyres on my C63S this time last year and have done 8k on them, which include a 2 day course, part of it on a track and they still have 5-6mm left on them. As others have said, get the geometry checked first.....

It's definitely an alignment problem. You need a full four wheel realignment by an expert (after the new tyres are fitted). You can then discuss optimum tyre pressures with him.

Post some photos of the alloys fitted , it'll be easier to determine what tyres should be fitted.
