tire pressure monitoring sytem issue
the tire pressure monitoring system warning light came on today on my way to work this morning i topped the tires off to the recommended psi (50) on the tires and the light went off. on my way home the light came back on. wondering what could be the issue?

50 PSI?!?!
The normal PSI on the OEM tires, and most tires you would replace them with, is 32-34 PSI.
The light comes on from over inflation as well as under inflation. It will flash if there is a system error.

They are definitely going over 50 psi once you warm them up, and just because it says maximum pressure 50 does not mean that is what should go in there. I generally air my tires up as cold as they get and shoot for 34-36 psi similar to what riwwp suggested.

He said he read the maximum pressure on the sidewall of the tire.

The tires are extra load. The load carrying capacity is higher than some cars. To reach the maximum load carrying capacity, you need to use the maximum tire pressure. Although it's almost never needed outside of truck tires.
If you look at the sidewall for the rated load in LBS at the maximum pressure, you will see that your whole car can be supported by probably the weight of 2 tires.
Not just a one time thing either, like jacking up one side of the car. The load capacity in actual pounds is designed for using the tire at speed and under heat soak.
It would do no harm to run that specific tire at maximum pressure. Its not necessary though. It will create a rough ride.

Probably one of the most common car ownership mistakes is thinking the maximum pressure on the side of the tire is the recommended tire pressure for driving. An unintended consequence of that poorly written and designed stamp.

I cant count how many times people have come into my shop with 50,60,70+ psi in the tires and when I ask why, the answer is: "I pushed the button on the air pump at the gas station. When it stopped, I moved onto the next tire and pushed the button again."

Though it does get a much rougher ride compared to recommended pressure. It will be more prone to understeer also.
