pretty sure that some type of TPMS is required on any car 2009 or newer. Our 2010 Malibu has one (display's individual pressures, front then rear)
I bought a Pressure Pro system for the truck and trailer. Monitors and displays all pressures and temp changes on all six tires on the Volvo and seven tires on our RV (I bought a sender for my spare, too
) Actually last summer one of my sensors failed, so I am no longer monitoring the spare tire.
Our 2008 Rabbit just had an idiot light when a tire was low, but you had to check the tires with your gage to see which one was low.
