Mitsubishi ASX - how can I reduce road noise?

How do I reduce road noise? Should I change to smaller tyres or put more soundproofing in the boot/wheel arches?

Switch to 16-inch wheels and Michelin Cross Climate 215/70 R16 100H tyres, or stay on 18s and fit with Michelin 225/55 R18 98H Cross Climates and run them as 31PSI cold pressures. Forget about soundproofing. Harbours moisture.
