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.
The correct tire pressure fixed the problem. :LOL:
