You HONESTLY think a Prius is capable of going fast enough to be concerned with that?
Drove one for 7 years. Would do 100 MPH. Was much faster than my 1978 Dodge Challenger or even 1971 Dodge Charger. Doesn’t compare to my Tesla Model S, but few do.
NHW20 Prius was 2900 pounds on skinny 185/65-15 88 tires. Most in that size were load range 86. Unlike “heavy sport-tourer” lore mandating “GT” tires which have exactly same load rating as non-GT, the Prius really did require a heavy duty tire because it was using a smaller than typical tire for its mass.
Tesla is similar in wearing 245/45-19 in a heavy duty class to carry 4900 pounds empty. It too can slide easy, but not as easˇ as the Prius.
Prius would easily go faster than traffic but didn’t take much to slide sideways. And that was my point, that anything sliding sideways is getting much poorer MPG scrubbing the tires than anything with fat tires following behind. That is exactly what Top Gear did in their Prius MPG comparison. Just as their dead battery Tesla was faked (Tesla has telemetry to prove). As was James May flying a blimp over London.
