Winter tire pressure

[phpyeung]

I got Nokian R3 on my Model 3. What is the tire pressure recommendation?

 

[mrElbe]

Tire pressure always as per label on door jamb.

Cold pressure is 42psi per Tesla, but I go up to 43 or 43.5 for better range. Ride will be more bumpy with higher psi.

If you are inflating indoors (like a garage) and it's very cold outside, you need to increase the pressure because the air will shrink. When it's well below freezing don't inflate outdoors because the water vapour in the air will hold the valve open and all the air will escape. Always use a valve cap that seals (it will have a rubber seal inside) to prevent air loss.

As per door sticker it’s 45 psi. Kaltire put mine at 41 psi.

My door says 45 psi, but I think Tesla at some point changed that to 42. I use 45 for range and tire mileage, but it is just a tad harsher ride than 42. As temperature decreases, tire pressure will as well so adding air is necessary.

Running 43psi (cold) and 45psi (warmed) for maximum range.

Tesla specs 42 psi or 45 psi depending on whether you are running 19" or 21" rims.

This is the COLD temperature; set it when the car has been sitting for a few hours. Also you should adjust the pressure periodically as it is temperature sensitive - try to maintain the same cold pressure throughout the year. When the tire is warm after driving the pressure can be 2-3 psi higher.

You can raise it a couple of PSI to reduce drag and increase range slightly, but this will also reduce tire grip so reduces your safety margin a little. It might cause very slightly more wear in the middle of the tread also. Personally, I try to stick to the manufacturer recommendation.

I try to keep around 40-42, but the cold keeps knocking it down to 37-39.

Does tire pressure relates to winter regen braking being not stable?

Does tire pressure relates to winter regen braking being not stable?

It is likely the lower temperature of the batteries that makes regen not as efficient in the winter. same reason charging is slower when batteries are cold
