XHIR-FM is a radio station on 103.7 FM in Ciudad Valles, San Luis Potosí, Mexico.

The losing bidders for the station attempted to dislodge concessionaire Enrique Cárdenas González, first before the Technical Consultative Commission and then in the courts.

Sindulfo Martínez Manzanares and Oliva B. Navarro received an amparo against them, but ultimately the courts found in Cárdenas González's favor and XEIR was cleared to begin operations.

That year, XEIR and XHIR-FM were transferred to Laura Cárdenas del Avellano.
