Some people on here have fit them with just a leveling kit, but others have said you'll need to do the pinch weld mod due to the width of the tires. Nitto makes the Terra Grappler in a size 285/65/18 which if I'm not mistaken is the same heigh as the one you're looking at but about an inch thinner. DiscountTireDirect.com has them for about $20 per tire than you're looking at for the kumhos.
