I was surprised to see that the recommended pressure for most cars seems to be 45 psi since my car says 42 psi. Perhaps that's because a 60 is lighter? Even at 42 my ride is pretty hard but my mileage is quite a bit less than EVtripplanner projections, although I need more data.
I never know what pressure to use since all of my trips involve going to lower altitude but often higher temperatures. Next month I plan to go from home (7670 feet) to sea level. I'll just have to keep an eye on the pressure and adjust as needed each morning.
Is there any consensus yet about the best LRR tire for 19 inch wheels? I have stock Goodyears at present.
Tire pressure recommendations are based on a set of assumptions. One of the assumptions is how it's going to be driven. I'd guess the Tesla engineers figure that the P85 is going to be driven harder than the S60 and that the S60 may carry multiple passengers more often.
I have too few miles on them to know how they will last. Regardless, because I drive steep, sharply curved mountain roads — plus some dirt/gravel roads — much of the time, I always get vastly fewer miles out of my tires than people who drive in cities and on interstate highways. So my experience wouldn't be helpful. I will say that the tires seem to handle well around hairpin curves.
