The title is misleading. I read it and thought one mechanically failed.
Title is - "We Drive Them Off-Road Up A Mountain, But Only Two Make It Back!"
I don't know how you assumed one mechanically failed. That on you. If you watch the video, they had to leave the Defender on the mountain until they could get a new tire put on the wheel another day.
Title isn't misleading at all.
Sounds like you're just really fanboying the Defending because a friend of yours has one and you think it's cool.
I don't know how you see a tire fail 2x and jump to "omg it must be staged. They didn't even film it! Fake news!"
It's a 5,000 lb SUV on pretty low profile all-season highway tires. Why do you think that it's out of the realm of possibility that it gets a pinch flat on SL rated 4-ply tires?
