09:05 Summary user results for Toyota Prius Plug-In Hybrid with 17" rims and "A" tyres
09:25 User real-life results for Toyota Prius PHEV Prime with "19" rims and "C" tyres

As always, I checked real fuel consumption on a petrol station. I noticed no difference: computer shows exactly the same fuel consumption to what I refueled for Prius Plug-In Hybrid 17" rims version. 19" version HIGHER the results by 2% (computer shows higher results comparing to what I refueled).

Prius Plug-In Hybrid tires: Yokohama BluEarth-FE AE30D 195/60 R17 90H with "A" efficiency index.
Toyota Prius PHEV tyres: Yokohama BluEarth GT (AE-51) 195/50 R19 88H with "C" index of efficiency.

Procedure:
I drive 33 km in both ways on a highway/motorway (16.5 in each direction). Energy consumption/economy in a city is measured in real-life traffic in Warsaw (Poland) in similar conditions: the same amount of heavy traffic, light traffic and quite similar average speed.
