    So a few days ago, I broke a rim after hitting a huge pothole. The rim was bent, but the tire was fine. The tire never ran completely flat. It only started losing air when the dented part was close to the ground. Luckily, I have a spare OEM rim. I put the donut on and took my car to the local...

    Why don't plane manufactures update their models?
