And look at the dent that steel rim took! I can't imiagine how hard you'd have to hit to bend one of those things like that. I'm particlualrly close to the "robustness" of the steel wheels after doing a tire rotation yesterday. Thank heaven the rock sliders and on-board-air mean it's only a one-jack-up and 20 zips of the impact driver per side (plus six for the spare). It was about 5 degrees out at the time. Call me mister procrastination.
