On my 2012 Sierra, it has the Tpms. Recommended tire pressure for the truck is 45psi front and rear. The winter tires I will be using have a max pressure of 44psi. I was curious if anyone knew how many psi below recommended pressure listed on the door I can go before the TPMS tells me my tires are low.
So if recommended is 45, can I run my winter tires at 40 without getting a warning. I could just not bother with sensors in the winter tires, but can't stand having idiot lights on.
