I put these on my 2013 700 Grizzly and they are a lot more aggressive than they appeared on line. The dirt and rock was perfect for traction and I could not hardly spin them. The 12 x12 x 26 is a very large tires. I am runnig 6 pounds in them and would not be afraid to go lower in areas that are not boulder strewn. The only reason I didn't rate them higher overall is because I only have about 80 miles on them in one type of country. I am going to Moab next month and the high country of Colorado in August i will write another reviews this fall.
