After much debate I purchased a set of Carlisle ACT HD tires for my 2013 Outlander 800. 26x9x12 fronts and 26x11x12 rears. I got a chance to take the outlander out for a test run this evening and even though my home is in the high desert, we have had a lot of rain this week. The lugs on the tires are almost one inch tall and they work well. The trails I rode on were very muddy and it is a very sticky type of mud. The ACT’s took it in stride and cleaned out very easily. Traction was very good and overall I am happy I picked these tires.
