Owning a big rig is a big problem if you're constantly straining to reach equipment stored on your sport rack or even attempting to wash the top of your SUV. The Durango TireStep: offers a big step up in lower back comfort. It's a durable steel adjustable step that neatly fits over the top of your truck, SUV, car and boat trailer tire. A skid-resistant plate helps hold you in place while loading or unloading your storage compartment in the rain, sleet or snow. The functional design provides added leverage for tasks like doing hard-to-reach engine repairs or changing windshield wipers. When not in use, the TireStep neatly folds down and stores in a durable carrying case that fits behind or under your seat or in your car trunk.
