Here what I found:

Older Michelin Carbon Width Height
------------- ---------------
2.4mm 4mm
New Krylion 2.3mm 4mm

So results show the newer tires are now a bit narrower than older version, which I am not happy to discover. I have not ridden the new tires yet and plan to return them and look for alternatives.
