TPMS malfunctions may occur for a vari
ety of reasons, including the installation
of incompatible replacement or alternate
tires or wheels on the vehicle that pre

Always check the TPMS malfunction tell
tale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
