Service Tire Monitor 04 Suburban

i bought this 04 suburban last year and replaced the factory wheels with 22" rims. now on my information screen or data screen the reads SERVICE TIRE MONITOR. i took it to the dealer and the couldn't remove that alarm from the screen. it is not affecting anything just annoying. you know. any suggestions or i just have to live with it.

thanks

Get the valve stems with the radio transmitters in them. The computer isn't getting a tire pressure reading, so it thinks something is wrong.
