Ive come up with more information about the tower! I repeat that im not the maker here's the link of the post:
http://leaguecraft.com/strategies/gameguide/208-game-mechanics-the-missing-manual.xhtmlAnother worthwhile fact to know is that towers have significantly more armor and magic resistance when no enemy minions are near, when an enemy minion comes into tower range, their armor and magic drops a large amount. Once the minions are killed, the tower will remain weak for about 5 seconds before the values return. Also, having a friendly champion near a tower gives it +5 MR / Armor.
When you attack a tower, it will take whatever is higher, you attack damage, or 40% of your ability power and apply that to the tower per auto-attack. Towers do physical damage, it can be reduced by armor, but not dodged.
It appears armor penetration has no effect on towers.
Towers grow stronger in damage, magic resist and armor throughout the game (until they reach their cap), still working out the exact mechanics of when and how much they go up by... They also gain 250 health for every disconnected or missing champion from your team

Quoted Text:
Towers get bonuses as time passes. The stat gain isn't the same. First they gain stats based on a set
I call 1), thereafter from a set I call 2); this cycle is repeated until the tower's stats has been capped.
Tower #1 gains:
1) +6 Damage, +1 Armor & Magic Resistance.
2) +6 Damage, +2 Armor & Magic Resistance.
Caps at 200 Damage (+48 damage). No further Armor or Magic Resistance is given after this point.
Tower #2 gains:
1) +6 Damage, +2 Armor, +1 Magic Resistance.
2) +6 Damage, +1 Armor, +2 Magic Resistance.
Caps at 263 damage (+66 damage). No further Armor or Magic Resistance is given after this point.
Tower #3 gains:
1) +6 Damage, +2 Armor, +1 Magic Resistance.
2) +6 Damage, +1 Armor, +2 Magic Resistance.
Wasn't long enough in the game to reach the cap. Speculating it's at +84 damage.
If Tower #1 is capped at +48 damage, Tower #2 at +66 damage I guess that Tower #3 may be
capped at +84 damage. This of course is only speculation.
Also I forgot to mention:
2nd Line towers start getting bonuses shortly before 1st Line towers finishes.
3rd Line towers start getting bonuses once 2nd Line Towers finish their bonuses.
I hope this help understanding the tower AI.
