Thats because of the weight of a Tesla more than anything else you previously had unless you owned a Sherman tank. The heavier the car the more the sidewalls will bulge therefor more PSI is required. I had 20" inductions on the Y which were swapped for 18" wheels and tires. Big ride quality difference with correct PSI in the tires. When I ordered the S I did not even consider getting bigger wheels, went with the no additional cost 19" variety.I am still evaluating by letting the tires naturally go down. Right now they are around 38 PSI, and I am liking that way more than 42. Tesla recommends the highest pressure of any car I know about, and it makes for a jarring ride.
Tesla has the highest recommended pressure of other similar or heavier EVs with similar tires. Many others are in the mid- to high-30s.Thats because of the weight of a Tesla more than anything else you previously had unless you owned a Sherman tank.
I inflate my replacement tires to the same specs as recommended for my 2022 Model Y long distance. 42 psi… and FYI, I only got 18,500 miles out of my OEM supplied tires. I rotated them 2x during that ownership period. Very sad about the poor performance of the OEM tires.
But what about heavier EVs with similar XL tires and lower recommended pressures? That would seem to counter this point of view. For example, isn’t the Ioniq 5 33 PSI? Are they doing it wrong?Note that Tesla specifies Extra Load (XL) tires for Model Y; XL tires only meet their maximum load rating when inflated to 41 or 42 PSI (European and US specs.) You can inflate to higher than 42 PSI but if you inflate to less than the recommended tire pressure the Tesla Model Y should not be carrying a full load of passengers and cargo or towing a trailer.
That’s fairly typical for non-EVs, even on XL tires. Way more comfortable ride. But efficiency takes a hit. ICE drivers don’t care as much as EV drivers.That seems low. Wonder if if they’re purposely sandbagging their own efficiency by running tires at low pressures.
My 2023 Ioniq5 Limited AWD door jamb sticker states 34psi for its 20” 255/45R20 105V, Michelin Primacy Tour A/S tires. These OEM tires have a max pressure of 50psi molded on the sidewall. I run 36psi on all four corners. Mine is the AWD version; those lucky enough to have been able to get a Limited RWD and all other trim levels come with 19” tires and I don’t know what door jamb states for pressure on those vehicles.But what about heavier EVs with similar XL tires and lower recommended pressures?

Same car 22MY LR, 19K miles. Have rotated twice as well. My tires are still fine with plenty of life left.I inflate my replacement tires to the same specs as recommended for my 2022 Model Y long distance. 42 psi… and FYI, I only got 18,500 miles out of my OEM supplied tires.

My app is saying 49psiDoor jamb tire information label on both the Y and S say 42 PSI. Not sure where the 40-45 comes from. Here is a link.
That’s insane. It’s got to be a glitch. 49 cold would be around 53-54 hot. Might as well be driving on plain rims!My app is saying 49psiView attachment 903314

See TRA P-Metric Load and Inflation Table (starts on page 13):
Look at the tires with an XL rating and load index of 101, 103 and 104 such as the 19", 20" and 21" tires for the Tesla Model Y (Although this table is for Toyo tires, in all cases the maximum load index rating (in pounds) is found at the far end of the table, i.e. 41 or 42 PSI inflation.

Crazy. Why would it say 49?My app is saying 49psiView attachment 903314
Would there be any issue with inflating to 50 psi?
