Nothing can slow down a field tech’s response time like Mother Nature — especially when it’s the first major snowstorm of the season.

Enter Thule, the sporting good giant. The company’s Easy Fit CU-9 snow chains are designed for one person to install. Slip the arched-chains over the top of the tire, wrap the bottom around the base, press down on the pedal that’s attached to the center aluminum bar and — presto! — it’s time to drive. That’s not all. When the car moves, the center bar automatically tightens the chain for a perfect fit. Even at $450 a pop, they’re still better than frost bite.
