This has been a problem for me with my car from the start. It's interesting that someone says in this thread that the level where the light is supposed to turn on is 26 psi. Mine seems to be anything under 32 psi.

I've not been able to go for more than a couple of months without the tire pressure light coming on. Every time I take the car to the dealership for 3k mile service, they without fail set the tire pressure to about 33 psi, which makes the light come on the next morning.

Now I have to replace my rear tires after 11k miles, and this situation leaves me not knowing if this may be due to too high pressure or too low pressure. Or did I just have sucky tires (or blowy)?

I've heard that 36 psi is the "correct" cold pressure. Is this right or wrong?
