Minimum tread on c63?
Discussion
It doesn't matter what car it is nor how many miles you drive.
The legal limit is 1.6mm. I generally replace tyres when they're worn to between 3mm and 4mm. Wet weather effectiveness (which is all I am really interested in) drops off quite quickly at that point. It's not like tyres are particularly expensive.

Legal minimum is 1.6mm but I'm sure from memory MB service schedule says 3mm minimum.
I'm not sure if being below the servicing schedule means it's not meeting the manufacturers spec and if this has implications for warranty/insurance.

there's definitely no insurance issues with the 1.6-3mm range.
Those saying those tyres need replacing, it'll only last a week are crazy - you only start with what, 10, 12mm MAX from new. So 1.4mm is easily 15% of your tyres life if not more. Although, once you're down to 2mm then clearly it's time to act, not least so you don't get caught out on a technicality.
However; Mainly due to convenience I did get them sorted over christmas. And wow - what a difference. I had the default conti sport or whatever that were already on the car, replaced them with pilot super sports, and the traction improvement especially in the damp is stunning. Suspect this is more down to the tyre itself rather than tread depth but still pleased I did it. And all 4 for less than 700 quid isn't too bad. (vs 800+ from merc)
So thanks, and happy new year all!

Not many, if any, tyres with more than 8mm tread depth new. 3mm leaves over 20% of usable life.

The recommendations to change at 3mm are commercially driven. There is a reduction in wet performance as depth reduces, of course, but a safe depth depends on many factors including type of vehicle, tyre brand and type of use.
Several years ago the tyre industry tried to get consensus from all the manufacturers to promote heavily that tyres should be changed at 3mm. Michelin refused to agree on the basis that their wet performance at 3mm was better than some brands with much more depth.
