Has anyone experienced problems with their OEM wheels on the BS?

I am in the process of ordering a C63 and wanted to have the 19" wheel pkg. (offered as an option for Europe) however was told this wouldn't be possible...as the U.S. is included on a list of countries where the roads are not suitable for this wheel.

My understanding is that the C63 wheel is identical to the ones delivered on the BS. Hence placing my question on this forum.

I have scannd through the posts on the BS forum and haven't come across anything indicating a problem. However thought it would be best to ask just to be sure.

If there are no widespread issues with this wheel I will go ahead and have my dealer order a set.

Any input would be greatly appreciated.

The offset on the BS wheel (25F 31R) will not allow it to fit on the C63.

Noted. However I believe that, offset notwithstanding, they are the same wheel.

How are your wheels holding up. Any cracking issues?

I believe not. The CLK (and SLK) Black Series wheels are forged, ang the 19" C63 wheels are cast (and lightly different in design).

Thanks for the insight on cast vs. forged. I'm surprised M-B would put cast wheels on their AMG line. However this would explain why they are having cracking issues.

Thanks

PS Good to know there are other 'believers' out there.

No issues at all.

I am not sure what wheels come on the C63 in europe or what wheel options are given to customers in Europe but the wheels on the US C63 look absolutely nothing like the BLK Series wheels. OTher that that I have had no issues with my wheels. No cracking or any kind of discoloration due to heat and reagular spirited driving.

Most AMG wheels are cast. The forged ones are an exception (usually one flavour per model) an usually much more expensive.

I don't experience cracking as much as bending. I've had a couple of sets of wheels repaired now (which works fine as long as the bent isn't too big and no cracks).

Aside from the slightly different design of both 19inch alloy rims. I believe the problem with the C63 versus the CLK63 Black series is the thickness of the tires as the thicker the tyre the more protection for the rim.

The C63 has the following profile: 235/35 R19 front and 255/30 R19 rear.
The CLK 63 has: 265/30 R19 front and 285/30 R19 rear

As you can see the tires of the CLK Black Series are thicker than the C63 AMG. That gives them an edge in protection against potholes. The 30 in 265/30 means the thickness of the sidewall is 30% of 265 (mm).

The optional 16 spoke 19" wheel that we can't order on our cars in the US are not the same as the 19" CLK Black rims.

Alls you need to do is look at a picture of them both and you will see they look nothing like each other.

This comment is a bit confusing. You don't mean thinkness here you mean height. The second number you are talking about is the aspect ratio. A 265/30 tire has an aspect ratio of 30% of 265 or 79.5 mm. a 235/35 tire has an aspect ratio of 35% of 235 or 82.25 mm.

In this example the C63 front tire should handle a pothole better as the distance between the road and the rim would be 2.75 mm more.

For street tires, typically the more aspect ratio the more compliant the tire will feel as it has more rubber to take up shocks ect.

The difference is, the BS wheel is forged aluminum and the C63 wheel is cast aluminum...........forged wheels bend, cast wheels crack.

If you are in the US, you'll just have to order the 19" from the parts dept. The PNs are in the C63 forum somewhere.

Anyone know what the BS wheels weigh? Should fit a 211 E55 right?


Thanks

Check your offsets (ET's).

front 9jx19 h2, 25mm ET, 24 lbs
rear 9.5jx19 h2, 31mm ET, 28 lbs

Offset is fine, I currently run 31 on the back and 30 on the front. PCD/bore should be the same I think..

My stock wheels are 28.5 lbs (front) 33lbs (rear), will I notice the difference?

There's only 16 spokes per wheel??? When I wash the car,why does it seem like there's 50 spokes per wheel.

........probably not unless your name is Jenson Button

Or you're stuck behind Michael Schumacher the entire race
