Hi all, I've just bought a 2014 Honda Accord EX CVT, and found that the tire valve stems of this car are made of brass. I know this vehicle equips the TPMS (Tire Pressure Monitoring System), and have two questions below regarding the TPMS; 1. TPMS valve stem material As far as I know, typical TPMS valve stem is made of aluminum (white color), and non-TPMS valve stem is made of brass. Can you check up your 2014 Accord which has the TPMS whether the valve stem is made of brass or aluminum? 2. Physical TPMS calibration button instead of Vehicle Settings There is the physical TPMS calibration button under the steering wheel (left-side). However, the Honda reference guide shows that TPMS calibration should be done through the Vehicle Settings in the display screen. Is it normal that the 2014 Accord EX CVT model has the physical TPMS calibration button? Thank so much in advance.
