4.5"/110mm wide tyres on surron? Such as ContiAttack SM 110/70

I imagine it would require fitting a wider fork & modyfying the rear arm. Anyone tried this?

On the back 4 inch is the limit and may require dishing the rear wheel, on the front with Fox 40 ,80 profile fit but are close.The additional weight is very noticeable.

i would love to have a fat tire on my surron but the rotating mass is just scary. many wider tires are nearly double the 2lb stocker.
