This morning, despite all tires having a minimum of 37psi, I got a low pressure warning. I checked with 2 gauges and both indicated that no tire was below 37. The recommended tire pressure is 35. So I'm not sure why I got this warning. True the temperature had dropped to the low 20s, but the tires were still reading at or above 37. I'm going to do a calibration as suggested in the manual to see if that takes care of it. When I picked up the car new from the dealer, they had the tires significantly overinflated to 45psi. That gave a harder ride, so I dropped all tires to 37-38psi. Has anyone gotten this warning despite pressures being at or above recommended pressure?
