Goodyear recommends regular pressure checks on aero tyres

ERJ staff report (DS)

Akron, Ohio -- Pilots and maintenance personnel must resist the temptation to follow the same schedule they would use in checking their cars' tyres to determine that their aircraft tyre pressure is correct, said Goodyear Aviation's Robert Robson.

"Aircraft tyre pressure should never be taken for granted," Robson said. "High pressures, high loads, and the different designs of aircraft tyres and wheels often cause assemblies to lose pressure faster than those for cars."

Robson advises daily aircraft tyre pressure checks, preferably before first flight. "Check pressures when the tyres are at ambient temperatures," he said. "Tyre temperatures can increase 200°F during aircraft operation, and every increase of 5ºF results in approximately a 1 percent pressure change." Therefore aircraft tyre pressure should never be reduced when the tyres are still hot.
