This time hopefully tire rotation recalibrated. Last visit we had tires rotated. Awhile later we got alert one tire low. It happened on a Sunday so first my husband put air in tire that was designated as low. Nothing changed on the car reading. Tried a couple of times Finally found a full service station and guy checked with his meter and found that tires were not coming up in line with the car read out. Finally figured out which tire was low; tire that was earmarked low and which my husband was filling was actually at 60 psi very dangerous. Told service station attendant that we recently had tires rotated. He said they probably did not recalibrate afterwards. He was right.
