Minerva FORTUNA WINTER CHALLENGER

2 months ago I put 4 of these on my 2008 Yaris along with 4 new shocks and wheel alignment. They are terrible! I can't do over 45 km/h in 5 cm of snow. Tonight on the 13 North I could not go faster than 65 km/h on 1 cm of wet snow. There were 3 of us in the car and the car was 'floating' over the 1 cm of snow. I have never felt so insecure with any other tire on any of my 3 vehicles. I am taking these back. BE WARNED - THIS NOT A SNOW TIRE!
