The Step-Up makes loading your car easy.Make loading your Combi Box or getting your freeride bike on your roof rack a little easier with the Thule Step-Up. This heavy-duty platform straps to either the front or rear tire of your vehicle, so you can actually see what you're doing on the roof. It works wonderfully on trucks or SUVs that are too high off the ground to comfortably load. The no-slip platform ensures sure-footed loading. The attachment strap easily runs around the tire and fits any vehicle regardless of wheel-well clearance. Thule includes a carrying bag, and the Step-Up folds flat for easy storage.
