How to Store Flat Tire.
1. Screw the shaft into the floor though the slit in the mat covering the trunk floor ( or luggage space floor). Insert a screwdriver in the hole present in the shaft end and rotate the shaft in a clockwise direction until it is tight. (Make sure the mat is not caught.)
2. Pass the shaft through any one of the lug holes in the wheel and tighten the wheel down with the holder until it is fully secure.
