I had assumed that the conventional wisdom was the bigger the wheels, the lower the range - presumably it is not the actual wheel size per-se but the wider tyres on the bigger wheels giving more air resistance (&/or rolling resistance??)
So the standard 21" on the 50 was fine for me.

What? Hold on, the 22's are more efficient than the 21's? Is a £1,000/£1,350 upgrade worth 10 miles? Or even a free (?) downgrade to 20's for 19 more miles! 19, that is more than most PHEVs can do on e-only!... indicating an EPA range of up to 324 miles with 20-inch wheels, 305-miles with 21-inch wheels and 315 miles with 22-inch wheels.
