Tires size possible deal breaker on 2023 Prius?

No one ever got a ticket because his speedometer read too fast.

I like the idea that the stock 17" wheel and tire size are a bit modest. This should mean that a tire replacement in 215/60 should be close enough and give a little extra sidewall.

While it's true that suspension and wheel and tire size are all part of suspension calibration, whoever does that calibration for Toyota must live in a world of perfect roads.

I first drove a current generation Corolla in 2019 or 2020. It had 18" wheels that made the car sound and feel cheap with lots of road noise. I eventually bought one and put 15" prius wheels on it.

People complain about the reduced efficiency and higher frequency of sidewall damage with stock 19 wheels, but the most frequently experienced downside will be noise and a perceived harshness of the suspension on rough pavement.

 

Yep! I'm using 205/55R17 myself as i wanted to be 100% sure they would'nt rub and i needed studded tires to get out of my driveway but some customers are reusing their Camry's 215/55R17 successfully on their Gen 5 Primes.
