In Birmingham, a variety of tyres for earth-moving vehicles are manufactured, including the largest all-nylon earth-mover tyre in Europe. These tyres undergo rigorous testing in a new laboratory to ensure quality, with capabilities to simulate various conditions. The tyres can carry significant loads and contain enough nylon to make thousands of stockings. The transcript also briefly touches on cultural trends like the miniskirt.
