Meaning..? 4?
I don't understand this setup. What does a tire by itself do when all other support fails?
So 2 trolly jacks that are just an inch or so lower than the jack stands?
how so?
I am trying to understand what are good secondary support options (in addition to the jack stands) to keep a vehicle from crushing you.
When I search online, I find people talking about using jack stands and having a secondary support from a tire. I don't understand what setup they are...
