Snow Tire Necessary in washington DC?

Sorry I can't type Chinese in the office.

Going to DC around Feb 1. I live north and currently have snow tires on the car. Are they necessary in DC? DO I need to change tires? Thanks a lot.

• 加拿大时都没用过雪胎。既然已经装了，不必换下来。我现在DC10年了。 -宰相肚- ♀ (0 bytes) () 01/18/2012 postreply 08:34:22

• 还是换吧，我最近滑了下，估计是轮胎，钱小事，安全是大事 -kdlk- ♀ (0 bytes) () 01/18/2012 postreply 15:26:21
