"      Price: $450 Snow chains are tough, but so is trying to install them yourself. Thule&amp;#039;s Easy Fit CU-9 system changes the game without compromising safety or durability. The rigid arch chains made of strong manganese nickel steel alloy fit easily over the tire. Just pull out the built-in pedal and push it down with your foot to activate tensioning. When the tire moves, the aluminum central bar automatically tightens the chains around it. An external release system makes removal just as simple. The Easy Fit CU-9 system also comes with optional anti-scratch nylon bumpers to protect alloy wheels. "^^<http://www.w3.org/2001/XMLSchema#string>
