Yet, many sites trying to underrate the sizes of the giant Tyrannosaurus rex(the king of dinosaurs). I found this study giving some clear data on size of these monsters…
"Body masses and COM positions
Table 6 shows our results for our five whole-body models. For
the four adult Tyrannosaurus models we obtained a wide range of
body masses and COM positions because our methodology
purposefully produced wide ‘‘error bars.’’ We expanded our range
of models to extremes that we qualitatively consider to be too
skinny, too fat, or too disproportionate. We did this with the
expectation that the actual (but effectively unknowable) body mass
and COMs would fall within this range. Body mass (for minimal
and maximal models; here rounded to nearest 100 kg) ranged
from ,5800–10800 kg for the comparably-sized Stan and MOR
models made by KB, whereas the Carnegie and Sue models made
by VA+JM produced proportionately larger masses: ,7400–
14600 kg for the former and ,9500–18500 for the latter. "

So, The Carnegie and Sue models had gave some larger estimates.
The lower estimate for the “Carnegie” and “Sue” is being 7400kgs and 9500kgs. And that is based on too skinny models. While the fat estimates being 14600kgs and 18500kgs.
Let's take the middle value of the largest most complete Tyrannosaur ‘Sue'. The middle value for the values 9500 and 18500kgs is 14000kgs(14 metric tons) respectively. Reply
