TPMS Tire Pressure Monitor Light 2010
I searched and got multiple TPMS threads, but not the answer I'm looking for. I swapped my 17" factory steel rims off my 2010 Ram for a set of 17" aluminum rims off a 2008. Discount Tire swapped the tires.
The day after I did the swap, the TPMS dash light came on and stayed on when I started the truck. I had driven approximately 70 miles before it came on.
The tire pressure is 34-35 PSIG measured with a high dollar calibrated Moroso tire pressure gauge.
I took the truck back to Discount Tire and they had a hand-held monitor that was able to read the four tires and the spare at 34-35 PSIG.
Reading the other threads, it sound like the system should have reset itself. At this point, I would just like the light off the dash.
Any suggestions?

A precise reading can still be wrong. It's just a wrong precise reading.
I aired the tires up to 40 PSIG and drove 2 miles. The light went off.
According to the door jam, the 17" tires recommended pressure is 40 PSIG.

hmmm, you correct with the tire pressure at 40psi
It could be a faulty sensor in one of the wheels, I would have dealer look, if your unable to figure out, sorry bud !!!

i also noticed my pressure in tires is different all the time, Ive been told the air temperature outside can cause a change in tire pressure
The correct tire pressure fixed the problem. 
i don't know hardly anything about the tire read out light
i do know about tire pressures though, the tire pressure should be set to the normal load that your vehicle carries, if you run with your bed empty most of the time, then your tires would only need 34 - 35 pounds of pressure, if you carry about 1/2 ton of tools or material in the trucks bed, then you would want to run 40 pounds, the numbers on the tires are for MAXimum tire pressure, the stamping or tag on the vehicle itself are only for the original tire size & type, so if the size & type has been changed, you may need to ask a tire guy, discount tire has a chart that they refer to
here is a reference for you...
