Could anyone of the 996 TT owners (with Pirelli P-Zero Asymmetrico tyres on their cars) comment on this observation:

Car has strong vibrations for the first 50 miles after a cold start in the morning. Could this be the typical behaviour of Pirelli P-Zero Asymmetrico tyres ??

I had this 996 TT for a testdrive and was not happy with this kind of performance. After abt. 50 miles of driving those vibrations slowly disappeared so I can only think of the tyres to blame for.
