The EZ Jack is an easy-to-use, safe and reliable device for changing tires on tandem axle trailers. Simply place the wedge in front of the wheel that does not need to be changed. Pull the trailer forward (or backward) up onto the EZ Jack until the flat tire is up in the air. Flip the wedge over (rocker side down) to function as an excellent wheel chock.
