I doubt the taxiways are that bad and the suspension on these aircraft are that bad
|Quoting Philsquares (reply 13):|
The "bobbing" effect you're referring to is very obvious in two conditions. The first is light gross weight. I remember flying the 727 and at very light gross weights, the pogo effect was very pronounced, but at higher gross weights there was almost no bobbing.
The second condition was if there was an aft CG. The moment arm from the center of gravity will make the aircraft more susceptible to the imperfections of the taxiways.
|Quoting Foxecho (reply 8):|
The possibility of a 'bulge' in tires is why when an aircraft is pushed back from the gate it is pulled FORWARD a few feet before getting pushed, therefore if a tire is bulged from sitting out there all night or whatever, the bulge is rolled out

Geoffm: It's more to do with the tactile/flexibility characteristics of the rubber than the movement of air from the top to the bottom. I'm not sure of the physics of expandability of nitrogen with reference to pressure/temps, but if you take your car for an example... it will develop a "flat spot" on the bottom if left stationary for an extended period of time. As it is made of rubber, the flat spot will rid itself in pretty quick time once rotation has started.
