Harsh ride quality in Range Rover Sport

I'm generally pleased with my recently acquired Range Rover Sport (owned for 2 months and travelled 5000 miles) but am unhappy with the ride which is much harsher and uncomfortable compared to our previous Discovery 4. I know the clue is in the name "sport" but can I improve it?

The villains of the piece here are the 21-inch wheels with 275/45 R21 tyres. They have the same effect on the Jaguar F-Pace. You need the smaller 20-inch wheels with 255/50 Pirelli P Zero tyres, or 255/50 Pirelli Scorpion Verdes. Far fewer sharp shocks.

Bigger and more economical than the old model. Great to drive on-road but with typical Land Rover off road ability. Fantastic traction and ability in the worst conditions.
