The 19 inch wheel Prius non plug in gets about 45 mpg at 70 miles per hour interstate based on multiple videos. That’s terrible.
Wayne at cleanmpg has shown several examples of the older Priuses with smaller wheels getting better highway mpg. Currently he’s been driving the base model 2023 version with 17 inch wheels and is getting 90 mpg but won’t state his speeds or driving patterns for some reason. He’s been advocating for smaller wheels also as an option out of the dealership.
One thing that’s nice about smaller tires, is they are much cheaper! So even if the gas mileage is barely a difference, the money saved by getting smaller tires every time you need new tires is a benefit right there

1) Statistically, for 50-weeks a year, the plug-in will use zero gasoline. That's it's advantage.
2) What was his back-to-back, A-B-A testing results, on the same car, with the two different wheel/tire combos, on the same day and test route, compensated for changes in 'weather'?
3) Lets see if anyone else gets 90 mpg in that exact car.
4) The price of tires is not germane to the science of mpg.
