A great front tire to go with this is the 31-15 tribute or the 32” leed screw. Like the blackbird, the blackbird PRO has become a popular choice over the last few years in the  UTV market and Buggies as well. Everything about this tire is the same as the blackbird with the  exception of width. The pro is an inch wider, With 3 paddle options it is a great choice for many  UTV’s. For paddle recommendations we have found #1 is what works well starting around  175WHP, once you get around 230 WHP its time to step up to the #2, and from about 320  WHP+ the #3 paddle. Although this tire can handle more horse power in many cases the  standard blackbird will work just as well or better based of the kind of riding you do and your driving style.
