Grizzly Tire & Wheel Combos Bigger tire help September 8, 2015 I’very got stock 25x10x12 and 25x8x12 tires on my 05 grizzly 660 and I found some swamp tires on Craigslist that are 27x11x12 and 27x9x12. My rim dimensions are 12×7. Will these fit ? Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
