Narrative:
Nosewheel tires installed backwards. Callback conversation with reporter revealed the following information: the reporter stated the design of the nose gear axle is straight and not tapered so the inner and outer bearings of the wheel are also identical. The wheels rptedly fit perfectly correctly; or incorrectly with only two discrepancies. One; air inflation valve would be located next to the strut and inaccessible to service the tires or check inflation pressure. The second indication is that the water spray chine would be located next to the strut and on wet runways could not deflect the water spray from the engine inlets. Embraer 135; 140; and 145 equipment rptedly has the same nose gear axle.

Title: AN EMB140 WAS DISPATCHED WITH THE NOSE TIRE AND WHEEL ASSEMBLIES INSTALLED BACKWARDS.
Narrative: NOSEWHEEL TIRES INSTALLED BACKWARDS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE DESIGN OF THE NOSE GEAR AXLE IS STRAIGHT AND NOT TAPERED SO THE INNER AND OUTER BEARINGS OF THE WHEEL ARE ALSO IDENTICAL. THE WHEELS RPTEDLY FIT PERFECTLY CORRECTLY; OR INCORRECTLY WITH ONLY TWO DISCREPANCIES. ONE; AIR INFLATION VALVE WOULD BE LOCATED NEXT TO THE STRUT AND INACCESSIBLE TO SVC THE TIRES OR CHK INFLATION PRESSURE. THE SECOND INDICATION IS THAT THE WATER SPRAY CHINE WOULD BE LOCATED NEXT TO THE STRUT AND ON WET RWYS COULD NOT DEFLECT THE WATER SPRAY FROM THE ENG INLETS. EMBRAER 135; 140; AND 145 EQUIP RPTEDLY HAS THE SAME NOSE GEAR AXLE.
