In a tyre, what main function does the casing serve as a load-bearing structure together with inflation pressure?

Correct answer

Support the load and maintain the structure with inflation pressure.

Support the load and maintain the tyre’s structure. Its behaviour also influences stability, comfort and performance; this does not mean it has no effect on overall grip. The bead seats the tyre on the rim and the tread contacts the road. Maintain recommended pressure and inspect damage; the casing does not replace the braking system.
