This is the big brother to the hugely successful 31” blackbird. As machines grow in size and power so do the world class tires, we bring to market! For many reasons the blackbird has quickly become one of our most popular over the last few years in the UTV market and Buggies as well. This tire comes with 3 paddle options, for that reason it is a great choice for many UTV’s from stock to highly modified. For paddle recommendations we have found #1 is what works well on stock machines, once you get around 200 WHP it’s time to step up to the #2, and from about 290WHP and 300+ you’ll need the #3 paddle. A great front tire to go with this is the 32” Leed screw, Or the 32-15 Big Tebo if you prefer a front tire with some Bite.
