Bought my 19 in March and with Covid19 enabling me to work from home, I just turned 1000 miles today. Fewest I put on a vehicle in 6 months by a long shot, I am usually a 15k miles per driver. Anyways, when I took delivery of the truck, I noticed on the drive home that the dash said the tires were at 40/41 psi and I thought the ride was a little harsh. Planned to lower them and just didn't get around to it until today. Took out my gauge, checked all 4 tires this morning "cold" which was 72F ambient. They were at 38psi...checked dash, 40 on 2, 41 on 2...thought my gauage was bad, checked all 4 with 2 other gauges I had...38psi...is there a way or procedure to calibrate the TPMS or does this mean sensors are bad/dealership visit?
