Filling with Nitrogen is just marketing waffle.
In high levels of motorsport (ie F1), pure Nitrogen is used because the tyre pressure rise with heat will always be a predictable known constant.
Normal air is mostly Nitrogen anyway, but contains varying levels of moisture. So the pressure rise with heat isn't as precisely predictable.
But that makes absolutely no difference at all on the road.
For your new 159Ti, make sure the front tracking is set to 0mm toe (parallel) and make sure the tyre pressures are correct.
Many ship with massive toe-out on the front and that will always rip through the inner edges very quickly on any car.
