Will it fit?
Yes.
Will it work?
Yes.
Is it recommended by the tire manufacturors?
No.
A better choice would be some 7" or so wide rims but eh, if this is all you have it will work for a while. Keep in mind the 31's will definately rub something with that much backspacing and the air pressure you'd need to run would be low...but still perfectly suitable for a light weight rig like a Suzuki.
