I don't know, Man, T-Rex has a hidden Advantage, Air sacs. Air sacs are used for breathing, they assure that oxygen rich air, flows continually, when breathing, in and out, it's very similar to that of birds. It's suggests that T. Rex needed to eat a whole Buffalo, every week to keep going. Plus, Considering the average T. rex clocked in at about .44 kilometers per hour fasterthan the average human, there's still a pretty good chance it could outrun whatever it wants to eat. But then again, 7-9 Tons is a lot of Weight, requiring a Full 2 Seconds, to make a 45 Degree turn, So I guess Ambush Makes more sense, But I'm not dismissing the idea, that T-Rex COuld still give ya a good run...

So in your opinion Tyrannosaurus would actually chase its preys for long runs? Something like wolves do? :)

Well... Ambush would make more sense, Due to its enormous size. Also, because its so heavy, requiring a full 2 seconds to make a 45 degree turn. It can't turn around quickly, if it's prey decides to bolt to the side. So, my opinion, it would've relied on Ambush, but it could also run, if it had to, More like a Grizzly bear. Still, look at ostriches, at how they run, and how they can do it for long periods. Just sum food for thought.

Ostriches have way longer legs (in proportion) than Tyrannosaurus and they have also way way stretched arctometatarsalia, while Tyrannosaurus had massive leg muscles and a huge pubic foot. One could say that the difference between a Tyrannosaurus and an ostrich is about the same that there's between a sprinter athlete and a marathon athlete. :)
And a bear is... well, a bear: there are so many differences between the anatomy of a theropod and the anatomy of a plantigrade mammal that you could compare their lifestyles, but not based on how they are "built". :) ;)
