Yeah, intentionally driving it like a regular hybrid once a week is a good practice. Pick a day where it has the best chance of getting fully warmed up.
I know there's no free ride. The fuel costs went down $150/mo and the electricity costs went up $50. At least my electricity prices are stable for the year and doesn't jump $0.20/L between 7:00am and 12:00pm for no reason other than "they can". I'm sticking it to the man! Toyota is sticking it to me with the 12V battery fiasco. I can't comment on the tire wear yet to see if the extra 300lbs makes that much of a difference.
That bit I tucked in based mainly on my daughter's Tesla Model 3, which seems to go through tire tread fast. Google AI concurred, citing increase weight and the near-instant torque of the electric motors. The 3 is all-electric, and significantly heavier, whereas the plug-in Prius versions are moderately heavier, and run in hybrid mode varying amounts, so it is somewhat apples/oranges. I looked up the weight, our gen 3 Prius versus a 3, the latter's about 800 pounds more. Also, maybe telling: the lug nut torque value is 129 foot/pounds. Yup...
