Wheel step-up step, DIY (TYRE STEP) 

I made a step on my wheel for easy access to the box on the roof of the car.
The stage is mounted on the wheel, well suited for access to the trunk on the roof. It is simply fastened around the wheel with a chain, the required length (length is adjustable), and firmly held in place, preventing the steps from slipping.
The step is folding and does not take up much space in the trunk, the folded dimensions are 50 * 25 * 4 cm. The dimensions of the step (platform) itself are 50 * 25 cm.
The step is made of steel pipe with an external diameter of 20mm. Weight 3kg.
