Today fitted replacement 265/35/18 sport contact 3 on my w211 with Amg alloys. The sc2s that came off showed evidence of cracking all the way around the inner wall between top of wall and tread. With the concern have also looked at the fronts 245/40/18 - same issue.
It transpires that continental know of the problem relating to "mo" fitments for tyres manufactured end part of 2008 to early 2009. They claim it is the way the tyre tread is wrapped round and bonded. My tyres were stamped wk 48/08.
Hence to say, my fronts are being replaced tomorrow with new sc3 rubber (that are apparently made differently) and the others are going back to continental for assessment and i guess part wear contribution / refund.
Continental technical claim they would pass mot as no reinforcement showing but to me these were without doubt dangerous and susceptible to pick up debris and potential blowout.
If you have these tyres - please check and reject if appropriate
