I thought I still had a bit of life left in my rear tires at 13k miles. However, on closer inspection, I am seeing strong wear on the inside edge. Anyone else see the same wear pattern? I did not expect this... alignment issue?




Notice deep wear on inside edge??

SBH-

holy ! alignment issues I guess?

Rear wheels always have a slight camber... I think that may be the issue.

I had this issue with my sedan and most likely face this on the coupe as I have lowered the car on KW HAS.

I think K-Mac have front and rear camber kits available Sanch.

Im fitting 295/30/19's to the rear of my sedan today and then will look at KW height adjustable spring kit if there's enough room to lower over the 295's.

Would be interesting to hear from anyone with camber kit experiences on standard height and lowered W205 C63S as it seems even standard height cars are cambering out tyres.

I'd rather spend the extra and just add the camber kits than worry about constantly clambering out front and rear tyres all the time.

Is the camber adjustable at all on our cars?

Or not enough toe in. I have been slowly adding more to my car to solve this problem.

Is it the same for both rear tires? I would say it's pretty normal for AMG cars due to the factory in-toeing and neg camber. Always check the inner edges from time to time to be safe.

I will wait it out until I see some tyre wear... I don't think its too bad.

I'm keen on getting new wheels so once I have bigger wheels on the car it might sort out a bit of the camber issue.

I thought that way as well! Static VS. dynamic toe can be an issue.

Fact is there is only "Toe” adjustment and/or tire rotation !

No Front or rear "Camber” to change tire contact angle to compensate if other than stock height or what is perceived average driving conditions.

No Camber (or Caster) to cater for high cambered roads, altering height, fitting wide profile tires/wheels, load carrying or simply having the availability of ongoing adjustment to return to factory specs after curb knock damage.

CAMBER – Allows to actually “change tire contact angle” resolving costly, premature edge tire wear, improving traction/understeer/oversteer (Toe only alters wheel direction)

CASTER – correctly resolves steering pull, increases steering response. With better turn in and high speed directional control, along with improved anti dive/lift under brake and acceleration.

We saw the need to design and manufacture “precise single wrench” adjustable bushing kits (ultimate – on car accurately/under load direct on alignment rack). These unique K-MAC patented design kits also at the same time replace the highest wearing suspension bushings.

Front Camber and Caster and rear Camber (with extra Toe to compensate for the new Camber facility).

No more ongoing trips to dealers or alignment shops or constantly changing tire brands.

All Rear – Camber and extra Toe #502226 $480
Front – Camber and Caster

C63/AMG, S63/S65 AMG #503316K $480

Delivery MB World members (USA/Canada) $30 one kit or $40 front and rear. Can pay by Paypal, Visa or MasterCard.

Freight to Australia?

What about a group buy?

NTRacing

Yes, problem is on both sides.

Anyone know what the toe spec is?
Recommended toe?

Thanks

Delivery Australia wide $22.


Re group buys - what we offer instead is one stop express air delivery USA/Canada (average delivery time is 3 to 4 days) direct to each purchaser! We subsidise the delivery cost for MB World members $30 one kit or $40 for 2 kits which is a third of the actual cost.

I would have this checked with the dealership and service shop first.

If the car is stock, this should be something they should seriously look into.

Try adding a sixteenth of an inch total toe in and see what happens. The thing is you have a wear pattern to go off of. Might as well use it as a guide. To much or to little toe in/out wears tires and uses fuel.

After reading this post, going for wider wheels without altering the camper may actually make this issue worst. Am I right?

If you just asked whatdya think of this tire, I would have said it's a rub, not an alignment issue. Hope that's not normal for these cars.

RDO247

Most performance cars will be setup with some degree of negative camber on the front and rear from factory.

Any negative camber in my experience with result in uneven wear.

I replaced my rears with 295/30/19's yesterday and my factory tyres had the same wear as the original poster.

When lowering your car this increases negative camber resulting in tyres wearing even quicker on the inside.

This is wear camber kits come into play.

These allow you to dial in and straighten up your tyres resulting in less wear.

You can see the negative camber in my cars rear.

Tell us about the new tires like ride firmness compared to stock and clearance --traction and general look. This is with stock rims??
thanks

SBH-

u can find the answer in another thread :p i just asked him over there called "increasing tire size" something like that
