TPMS psi ?

At what PSI is this thing supposed to come on? Reason I ask is that mine did come on the other day and all tires were above 58 psi (fronts 58 psi and rears 60 psi). I thought that I read somewhere that it was 55 psi which is what the computer was set for? Is this incorrect?

I think it depends more on what the original PSI the stock tires were supposed to be....I dont think its set the same for every truck.

2 to 3 psi variation in gauges isn't unheard of either.

My truck is supposed to be set at 65/65 but the factory set it at 50/80 as if I had ordered the camper package, it should tell you on the door jam.

not sure on the ford. but the toyota's have a sensor in the spare also. it may be low causing your tpms light.

mine came on when the temps dropped to below -20
I checked the tires and they were all at 45 PSI, I only have 500 miles on it and can only assume the guy doing the PDI didn't adjust the pressures

Thats really low for E range tires. I run 60 all the way around.
