Putting a wider tire on ninebot S2

[Stefce]

Hi the tire stock is 14x 2.125 which is pretty normal

I looked i found a 2.5" tire and also a 3"

They come up 50$ to get one so getting 2 is 100$ which is expensive.. 

I wonder which would fit..space i gave until the plastic guard is around 13mm which comes to a 26mm  total width increase possible..wider size it wont me much of i problem i think..hight would be the problem..
