-Flight Mate (Butyl) tubes comply with the requirements of SAE document AS 50141. |
These tubes are worth the extra money. I’ve had the cheaper tubes just start leaking without cause. Since I’ve been using the Goodyear Premium tubes, they last as long as my tires. My plane is a leaseback so it easily gets 1200 hours per year. With Goodyear Flight Custom III tires and these tubes, I easily get 500-700 hours on them without having to do anything with them except check tire pressure.
