I appreciate the creativity. If this were Tyrantrum's best set, he would probably end up ru. I think with his sweeping options he will be uu, they r more of his niche. Nice set though
Here is my reasoning as to why I think Tyrantrum will end up UU. Some Pokemon are dropped into lower tiers simply because their is something that outclasses them in a higher tier. Two examples I can come up with from last generation are Rhyperior and Machamp. Rhyperior had beastly offensive and defensive stats, so much that on paper he looked like a definite OU Pokemon. However the fact was, that in OU Hippowdon outclassed him as a physical wall with strong offensive capabilities. In terms of type, Hippowdon lacked the two 4x weaknesses of Rhyperior while maintain its strong physical bulk. On top of that Hippowdon was able to tank special hits better with some investment. To top it of, Hippowdon gained reliable recovery in Slack off and supported its teammates by summoning infinite sandstorm(even though it isn't infinate anymore). These factors put Hippowdon in OU while Rhyperior in UU. Even so, Rhyperior has its potential in OU, its just the fact that he is outclassed by another Pokemon that caused him to remain in lower tiers.
Next lets look at Machamp. He has always been a powerful bulky fighting type, but with Gen 5 came a strong competitor in the form of Conkeldurr. Conkeldurr sported better physical defenses, recovery in the form of Drain Punch, and STAB priority in Mach Punch. He fills essentially the same role as Machamp in UU as a bulky fighting type. That isnt saying Machamp isn't a bad Pokemon because it certainly is not. It is simply that there is a better option with Conkeldurr. However Machamp does hold its own advantage over Conkeldurr in the form of No Guard Dynamic Punch which everyone knows is a nuisance to face.
Now lets look at Tyrantrum. For this example I will use 4 Pokemon. Rampardos, Aggron, Tyrantrum, and Mega-Tyranitar. Lets start with Rampardos. One of his major roles is as a terrifying Head Smasher with the use of Choice Band or Life Orb. However why does he sit all the way down in NU with that attack stat. One major reason for this is Aggron. Aggron fills a similar role in RU but outclasses Rampardos in many aspects. Aggron superior bulk and typing allow to have better opportunities to patch up its speed with Rock Polish or Autotomize and then Head Smash away. On top of that Rock Head provides a recoiless Head Smash which gives him another advantage over Rampardos. Now its time to look at Tyrantrum. This analysis is assuming he will eventually receive Rock Head, as it seems inevitable since it has been seen on opposing Tyrantrum's by several people. Tyrantrum, sports high defenses, more attack than Aggron, arguably better typing, and faster speed. In fact, Tyrantrums 71 base speed allows him to reach a crucial speed tier as many people have already noticed. Tyrantrum fills Aggron's role in RU but even better with more power, speed, and coverage options. Just to see some of Tyrantrums UU capabilities, a Jolly +1 252Atk LO Head Smash coming from Tyrantrum does 63.17-74.85 to eviolite Gligar, a guaranteed 2HKO. With this much power, why does he not look like OU material. Six weaknesses, all to common attacking types is one thing, but another reason is Mega-Tyranitar. Mega-Tyrantar sports the same speed as Tyrantrum, however with superior attack and defenses. Thus he has more opportunities to set up DD or Rock Polish than Tyrantrum gets in an OU setting. Although Tyranitar does not have access to Head Smash, its bulk alone is a good enough trade off for the loss in power to outclass Tyrantrum in this role. This isn't to say Tyrantrum cannot function well in OU as it does have the advantage of not taking up a mega stone slot.
So to summarize Mega-Tyranitar>Tyrantrum>Aggron>Rampardos so it is logical to predict that they will end up OU>UU>RU>NU respectively. However that's just my theory.
