Tire pressure issue

[neilostroff]

Good morning

I have 2023 model Y long range with 3500 miles.

Tire pressure was always regulated to exactly what I wanted which was 42 cold. I live in Miami so I understand when it goes way up when I’m driving in the heat.

My issue is I had my tires rotated last week at Tesla and now two of the tires are at 42 when I get up in the morning but the other FL and RR are at 44. I’ve tried lowering the pressure in those tires to 40 and driving around a little bit and still the system tells me that those two are at 44.

Does anybody know if there’s a way to reset the tire pressure readings?

Thanks, Neil in Miami.

Since your tires were just rotated it’s possible the sensors don’t yet know which location they are attached to. You may be letting air out of the wrong tires. I really don’t understand how the sensors learn where they are, or how long that takes. Maybe @Discount Tire can jump in here and explain?

I would set the tire pressures evenly first thing in the morning and avoid having the car parked in the sun before you do this. Just having the sun shining on one side of your car will cause those tires to heat up and increase in pressure.

The Tesla Model TPMS is an auto relearn system and takes only a few minutes of driving to reset. We are not aware of any software recalibration that can be done, however a visit to your Tesla dealer might be in order if the sensors are defective.

You can also force the car to relearn/reset tire settings and reset the mileage for another 6,250 miles.

2 psi is almost nothing. The error in the system is probably 2 psi or so. You'll drive yourself crazy trying to get all the tires to the EXACT same pressure.

In my experience the TPMS readings for most late model cars are very accurate and the error is way below 2 psi. Being OCD, I can report that if the car is parked somewhere where the temp is constant across all 4 tires ( under ground parking garage for example ) and the pressure is set using a high quality tire gauge then all the TPMS readings will be the same for both my Teslas.

This exactly.

I would do the reset procedure above and report back.

This is a known issue. I have mine rotated front to rear, and TPMS is still wrong after many miles and also after resetting.

Ten years ago I got a flat 100 miles from home. Put the spare on and headed for home.

Twenty five miles down the road a Low Tire light comes on (middle of no where, no spare). It didn't say which tire or the pressure, just Low Tire. I pulled over, everything looked good. Restarted the car, no error message.

Another 25 or so miles I get a Low Tire message again. Pulled into a gas station and checked all tires. All okay, I hit the road again.

The third time I got a Low Tire message I realized the flat tire in the trunk was sending the message. Kind of like an old girlfriend, you put her away and move-on, but she keeps calling.

My tires all fluctuate about 1-2 psi being in the same garage from day to day.

Thanks everyone- I filled out a service request for the reason stated.
They gave me an appointment for Friday at their service center- I replied with my home address and they should me here by noon on Friday.
