B: That's exactly it.
Some of the guys thought that it would be much easier; that their pulls (no matter how much more they were pulling), would be lickity split. I'm very sure you would have pulled a HUGE tired dead, B. There's just no doubt about that!!!
People also have to take into consideration the height of the lifter (there were some tall guys out there), and your weak point in the dead.
However that, there were some mighty big lifts happening. I do have to say that tire deads make for a fun event for the spectators.
