A great front tire to go with this is the 31-15 tribute or the 32” leed screw. 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 is our only tire that 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 its 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 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.
