The tire pressure monitoring system (TPMS) in 2008-2016 Chrysler Town & Country vehicles monitors air pressure in the four road tires (excludes the spare). Pressure in the spare tire is not monitored. There are two tire pressure monitoring systems available, a base system and a premium system. The base system does not specify how many tires are low or where they are located. The premium system does so.
