i wanted to get new tires for my sportsman, the front size is 26x8x12, and rear is 26x11x12, but it is hard to find them in that size, would i be okay to put 27's on it or will i have to put spacers on it to keep it from rubbing,and if so how much does the dealer charge to put them on. thanks guys for your help!!

you will need spacers if you go wider up front.
