I don't do retreads. Strictly personal preference...just sayin'.
Gary, ALL the airlines put retreads on the jets.
In over 20 years working on DC-8,DC-10,B737, B757, B767, MD-80,DC-9 I have never installed a "new" tire. Never,
The only new tires I ever saw were Boeing factory tires installed on a brand new 737-800, and there was "Boeing" moulded into the sidewall....
I'm "testing" the Desser Monster Retreads, but since I only change tires every 10 years, it will be a while to see the long term durability, and I'm in a hangar so weather checking/ sun damage is also minimal.
