I am not going to pull an already flat tire up on a block or blocks because the tire itself is already stressed by the time you pull over and pulling it up onto a wooden block runs the risk of further damage to the tire and sidewall...
You do it your way and I will do it the way I have for over 50 years without issue..You certainly won't change my opinion on how to change a tire in the backcountry and I am sure the same applies to you and my opinion..
So I agree to disagree rather than an internet rant!
