Fiat LINEA T JET Tyres

I have a Fiat Linea T-Jet car, a 120-horsepower 206 Newton meter torque. On average, I drive 10 km a day, 20 km highway 20km highway. Over 80 Km / h the Conti is very, very loud. On the ice and on the ice soon lose the grip! Aquaplaning should only be expected at higher speeds. It behaves fairly well in rain and dry roads. Flat road and city for cars with lower power and torque, or ESP and torque-controlled cars. The 2003 Semperit SportGrip and the 2008 Dunlop Winter Sport D 3 are better on snowy and bumpy roads and quieter! Wear-resistant, after 10,000 km of running, 7mm of the first driven, 7.7mm rear tire. I thought better, I expected the right from the world famous Continental brand! Could the Conti 860 S have to be bought? If you have someone's experience, please write it.
