The way the system works IIRC, is that it uses the ABS sensors to measure the rpm of each wheel and if one is turning considerably faster than the others it triggers a low pressure warning - ie: a "flat" tire has a shorter circumference and therefore turns more rpm per given vehicle speed.
My guess therefore is that it's all relative - and there may not be an exact psi reading that triggers the warning.
Standing by to be corrected LOL.
