Most threads about putting larger tires on these bikes talk about rubbing issues, ive read them all (I like fat tires too)
I wish someone would have given you more advice, or the right advice the right way for you, I hope you have enough slack to get it moved out enough without causing other problems.

Dunlop Alpha 13.

They're on the race bike, a New Gen Ninja. They don't rub at all and stick like glue. 150/60-17.

I do, however, have suspension properly sprung for rider weight. See below, allowed rim width is 3.5-4.0. DOT tires, good for street use.
