What size are airplane tires?
27 inches
75 R15, which means they are 27 inches in diameter, 7.75 inches wide, and they are placed on a 15-inch rim. This is much smaller than a semi-truck tire, which can be over 40 inches in diameter and almost 20 inches wide.
How often do airplane tires need to be replaced?
every 120 to 400 landings
Tires are changed every 120 to 400 landings depending on a number of factors. Aircraft tires need to withstand an extremely wide range of temperatures that go from minus 60 degrees Celsius at an altitude of 10,000 meters to extremely high temperatures when landing in the world’s hottest regions.
What ply are airplane tires?
Typical light airplane tire ply ratings (PR) are 4, 6, and 8, with 4 and 6 being most common. The Cessna 180, which has a maximum takeoff weight of 2,800 to 2,950 pounds, requires a 6-ply-rated tire.

How often do airplane tires get changed?
How do airplane tires not pop?
The mechanics take off the hubcap and reduce the tire pressure from 200 to 30 psi, which reduces the risk of it exploding as the bolts and nuts holding it on the plane are removed. A sleeve protects the axle, and a lifting tool pulls the tire off. The axle sleeve is then greased, and the new tire is slid smoothly on.
What does a green dot on a tire mean?
Awl vents are of a defined diameter and are made to a defined depth at defined points around the tire. An amount of green ink is deposited by the tool on the sidewall as the hole is made. This green spot indicates the location of vents around the tire and shows the venting process was completed.
What does a blue dot mean on a tire?
The blue dot represents the high runout location on the wheel, while a red dot on the tire represents the coordination runout position on the tire.
