XHTIM-FM is a commercial radio station in Tijuana, Baja California, Mexico.

Broadcasting on 90.7 FM, XHTIM is owned by MVS Radio and carries the La Mejor Regional Mexican format.

It was owned by Carlos Armando Madrazo y Pintado and was eventually sold to Sociedad Mexicana de Radio de Baja California, which in turn sold the station to MVS.

In 1998, the station flipped to pop music as Pulsar FM, and the next year it became XHTIM-FM with a Regional Mexican format, first as X97.7 and later as La Mejor.

The transmitter was also moved from the MVS studios in the Agua Caliente area to Cerro Colorado.
