So My 660 Grizzly is ready for a new set of tires. I am strongly considering a set of Grim Reapers to install on my factory steel rims. I am also planning to go oversized from the stock 25x10x12 rears and 25x8x12 fronts. Just wondering if the added weight and size would be detrimental to overall performance. The size i'm considering is 26x11x12 rear and 26x9x12 fronts. I know the 8 ply of the grim reapers almost doubles the tire weight. Also wondering if a should expect any clearance issues. Any comments are appreciated!
