Narrative:

A back course localizer approach to runway 06R was flown to a normal landing and we exited the runway on a highspd turnoff. There were not abnormal control problems or noises throughout the maneuvers. The aircraft was difficult to steer once on the txwys, the nosewheel steering being minimally responsive. It felt like we were on an extremely slick surface. The WX was particularly bad with strong winds, snow, and low temperatures, so neither the first officer nor myself found the difficult steering unusual. After a short time, however, we saw another aircraft taxiing with far less difficulty than us, so we stopped and called for assistance. We were informed the nose tires were flat. We were towed in from that point. This was my first experience with flat nose tires, and I quickly attributed the steering problems to field conditions. A bad choice. My data base is now larger.

Title: 757 EXPERIENCES DIFFICULTY IN TAXI OP. DISCOVERS THAT THE 2 NOSEWHEEL TIRES ARE FLAT.

Narrative: A BACK COURSE LOC APCH TO RWY 06R WAS FLOWN TO A NORMAL LNDG AND WE EXITED THE RWY ON A HIGHSPD TURNOFF. THERE WERE NOT ABNORMAL CTL PROBS OR NOISES THROUGHOUT THE MANEUVERS. THE ACFT WAS DIFFICULT TO STEER ONCE ON THE TXWYS, THE NOSEWHEEL STEERING BEING MINIMALLY RESPONSIVE. IT FELT LIKE WE WERE ON AN EXTREMELY SLICK SURFACE. THE WX WAS PARTICULARLY BAD WITH STRONG WINDS, SNOW, AND LOW TEMPS, SO NEITHER THE FO NOR MYSELF FOUND THE DIFFICULT STEERING UNUSUAL. AFTER A SHORT TIME, HOWEVER, WE SAW ANOTHER ACFT TAXIING WITH FAR LESS DIFFICULTY THAN US, SO WE STOPPED AND CALLED FOR ASSISTANCE. WE WERE INFORMED THE NOSE TIRES WERE FLAT. WE WERE TOWED IN FROM THAT POINT. THIS WAS MY FIRST EXPERIENCE WITH FLAT NOSE TIRES, AND I QUICKLY ATTRIBUTED THE STEERING PROBS TO FIELD CONDITIONS. A BAD CHOICE. MY DATA BASE IS NOW LARGER.
