The best on the market at the moment are either nokian hakapelita r (i think it's R but I may be wtong, they change the name every other year) Or continental ice contact 5. However they are expensive.
I curently have a set of toyo winter tyes on my puma, and a diferent model toyo on our volvo.
Personaly, if Mony was no object, I would get the conti's. we sell a lott of them at work, and my personal experience is that they are werry good..
I have a complete set of Michelin Alpin A4's in 195/50 R15 on original rims. Michelins are very balanced, have low rolling resistance and quiet in operation. Good in dry amd wet, very good on snow. Strongly recommended!
