Hey guys, been looking at the Grimm Reaper and Sparticus tires for my 2010 Brute 750i. (although I am leaning towards the Zillas....) They only come in limited sizes for the 26" height. Specifically, 26x10x12 (F) and 26x12x12 (R). Does anyone out there have experience with trying out these sizes on the BFs? I measured the distance between my OEM "tire" and the gas tank encasement and it looks to be tight. Will I need wheel spacers??
