Save time and money, with VViViD's Folding Tire Grip Planks. Stuck in snow, sand or mud? No need to call an expensive tow service, or even let it interrupt your day; simply unfold these 2 x tracks, wedge them under the pulling wheels, and slowly drive your car, SUV or truck (yes, these will easily support a full-size pickup!) out onto stable ground. With 2 flexing hinge-points in each plank, these tracks conform to the shape of even very rough ground, providing constant traction throughout the retrieval process. When done, wipe them off and store them in your trunk; at 11.75” x 7” inches folded, and approx. 1” inch in height, they barely take any space, and won't rust or corrode. Stay safe, stay mobile, with the VViViD Folding Tire Grip Planks
