Maintenance Tire warning.

Yeah, I also suggest to reset with a TPMS diagnostic tool, as what my friend also said

If the yellow TPMS warning light came on right after changing tires, the tire shop may have damaged one of the sensors. Or if your car is several years old, one of the sensors may be dying (their internal batteries are not replaceable) and it may just a coincidence that it happened right after replacing tires.
