Narrative:
I had gotten just wet runway reports from 3 flts and the field condition report stated runway 17L/35R wet with braking action good. Both runway 17L/35R and runway 12/30 are grooved and runway 17R/35L has porous friction overlay so I released flight dfw-cos with #2 thrust reverser inoperative. Though there was still precipitation, I felt that the runway would be good. When flight landed, captain had trouble stopping aircraft and put flat spot on all tires. Supplemental information from acn 400013: aircraft landed and reported runway slippery that he could barely keep aircraft on the runway. He blew 1 tire and balded the other 3.

Title: DISPATCHER RPTR'S ACR MLG RELEASED FLT WITH INOP #2 REVERSER. BRAKING ACTION WAS CHANGING AND WHEN THEIR ACFT LANDED, RWY WAS FAIR BRAKING, RESULTING IN 1 BLOWN TIRE AND FLAT SPOTS ON THE OTHERS.
Narrative: I HAD GOTTEN JUST WET RWY RPTS FROM 3 FLTS AND THE FIELD CONDITION RPT STATED RWY 17L/35R WET WITH BRAKING ACTION GOOD. BOTH RWY 17L/35R AND RWY 12/30 ARE GROOVED AND RWY 17R/35L HAS POROUS FRICTION OVERLAY SO I RELEASED FLT DFW-COS WITH #2 THRUST REVERSER INOP. THOUGH THERE WAS STILL PRECIP, I FELT THAT THE RWY WOULD BE GOOD. WHEN FLT LANDED, CAPT HAD TROUBLE STOPPING ACFT AND PUT FLAT SPOT ON ALL TIRES. SUPPLEMENTAL INFO FROM ACN 400013: ACFT LANDED AND RPTED RWY SLIPPERY THAT HE COULD BARELY KEEP ACFT ON THE RWY. HE BLEW 1 TIRE AND BALDED THE OTHER 3.
