I just got my cobalt just wondering if i need snow tires?

I assume you mean you got the s/c, in which case you get the p-zero rosso. If you get lots of snow/slush/ice I would definately get snow tires. I tried using the p6 4 seasons in the snow and they performed terribly. The p-zero would probably do worse. I myself am getting either the snowsport 240 or LM-25 for mine when the snow starts coming. I also got a winter set of rims which you might consider.

Please post topics in the appropriate forum.
