Rear tire wear
Hi guys,
So I'm running Conti DWS 06 tires, and I'm down to the cords on the inside. Now, I did have an alignment a little too late and had some bad uneven wear - obviously it didn't even out, but I think the inside still has very accelerated wear? (I did get it done @ dealer) I am aware of the stock camber but am wondering if the stock camber causes this for you guys?
I know that K-mac sells kits and I think there are some oem "extra?" Camber bolts, but I don't remember this being an issue on my stock setup, only my aftermarket thus far.
Any ideas appreciated

1/8" toe in is quite a bit for a street car. Stability exiting a corner under power is not worth constantly cheese grading the rears. Zero that out.

I appreciate your help guys.
Here's where I am a bit confused - I had cupping in my rear tires with the alignment at the top of the page in the picture. The tech was aware of this so I'm not sure but wouldn't this then have been the complete opposite solution to the problem?
And, can I adjust these myself without the machine, or do I risk screwing it up completely?

Unfortunately most guys who work at the dealership don’t know much other than follow what a book says or put the car within spec. Cupping is usually something bent or worn out but yes increasing the toe In is definitely not going to help

toe out the the inside.
the reason your tires wore on the inside is because you had it too neutral or toe out.
Do not adjust it keep it where it is.
your before toe is the reason why the tires wore so fast on the inside.

If the alignment on the rear tires is set to neutral toe in will flex to toe out under acceleration and will wear the inside of the tire.

Just curious do the rest of you guys run 2 pairs of rears for every 1 set of fronts (lifetime?)

could be I had some cupping on one of my front tires when I changed them and went over all the suspension and alignment settings and couldn’t spot the culprit either but I did notice my shocks are getting to the point of needing a replacement guess it’s time for some kws

Wow those look great but pretty pricey lol
Here's a pic of my current rear-right wheel

Dumb question but you can see there's lots of tread on the center...is there still life left for these or should I switch now
Also wouldn't camber be contributing to this moreso

These cars just run too much negative camber from factory, these are really the only way to correct it.
Good luck.

With the current camber settings and 0 toe he would still get inside wear because of the camber, but, his tires would last longer than leaving the current positive toe setting.

yes it’s the combination of a lot of camber and toe. You have most of the vehicle weight riding on the inner tire and then then the high amount of toe making the two wheels in effect driving in towards each other creating a scrub like effect on one another

Sure, if negative camber wasn't part of the equation.
Lol maybe if he was at max acceleration 24/7...

pretty much under any acceleration he will have negative toe and that under torque and weight transfer where the tires wear out the most.
take a look at this video there you can see how much the rear suspension flexes under acceleration.
6:20 shows it the best. I know it’s not c63 but I would expect similar results.
negative toe will wear out the inner edge of the tire and not just the inside like with negative camber.
the rear alignment needs positive toe in combination with negative camber.
for the front Alignment that is a different story neutral toe would work just fine unless it’s a 4wd or fwd car.

For some reason I can’t see the picture of your rear tire.
you can pick up some adjustable rear camber arms for $180 on eBay.

Lol, if the mb techs see that sheet:
"OmG hOw dO yOu eVeN dRiVe tHis iTs UnAliGnEd"
-$6000 alignment
"OmG hOw dO yOu eVeN dRiVe tHis iTs UnAliGnEd"

I have almost the same alignment specs and the same results tire wear is even and I get almost twice the mileage out of the rears that I did with the factory specs
