CAUTION:  Emergency Tire Chains are legal in all states.  However, emergency tire chains are meant for short distances only and may not be legal when state authorities post "TIRE CHAINS REQUIRED" ordinances on highways.  Emergency tire chains are an excellent traction aide when you are already stuck or anticipate getting stuck.  Their easy installation and removal make them an ideal safety item in all vehicles. Emergency chains are designed for emergency short term  use only!  Emergency chains are not designed for any continuous driving.  Another restriction of use is that these types of products can only be used with slotted wheels.  In addition, we always recommend the use of at least one pair per drive tire, mounted opposite of each other.  The purpose of these devices is only to get the vehicle  UN-stuck from a parking lot, driveway, side street, etc.  Emergency chains must be removed before continuous driving.
