30″ Silverbacks… Will they fit?

outlander 800xt G2 i have heard about people doing some extension for larger tires but would really rather not. I have 28" mega mayhems on stock wheels with a 2" lift and everything fits great.

There’s a great deal locally on some almost new 30" backs on 14" wheels and I’m wondering…..wil they fit?

Pictures are a plus! And as always thanks guys!
