Bentley has announced a new 22-inch carbon fibre wheel developed specifically for the Bentayga.

The wheel, engineered with renowned carbon fibre specialists Bucci Composites, is to be the largest carbon wheel in production in the world and offers a vast range of benefits beyond the initial 6kg improvement in unsprung mass per wheel.

The carbon fibre rim reduces unsprung mass by 6kg at each corner
The newly developed rim has undergone the most rigorous testing for non-metallic wheels including biaxial stress testing, radial and lateral impact testing for simulating potholes and cobblestones, tyre overpressure, and excessive torque tests exceeding the permitted limits.

The carbon rim is also said to be extremely safe.

While a severe impact which would crack or shatter an aluminium wheel and cause a tyre to collapse explosively, the carbon fibre rim allows a slow tyre deflation thanks to the intelligent layering of fibre weaves, allowing the vehicle to come to a controlled, safe stop.
