Installed yesterday and driven home last night. First impressions -easier to steer, softer ride, more stability. Fronts are 26x9R-12 and the rears are 26x12R-12. They look huge compared to the stock tires. The reason I went with the original Bighorns is that I read in other forums (and here) that the 4/5 Lbs per tire lighter weight of the Bighorn 2 came about because of thinning the sidewalls and lugs. Some people were of the opinion that the thinner sidewalls contributed to more flat tires but I wouldn't know one way or the other. Time will tell and I know that my type of driving at my age is not hell bent for leather over terrain full of sharp rocks - if anything it's probably frustrating to the young turks behind me in their Rzr's. A few pics of tires that you have all seen before.
