Knobby Tires

The Knobby Tire Series supports community based cycling and the associated health benefits.  We are Idaho’s state championship series based in Southern Idaho.  We try to create a family friendly environment so everyone can come out and enjoy a day on the trails.  However, none of this would be possible without the generous support of our sponsors.  When you get a chance make sure you thank all of those who support the sport we all love

Are you looking to qualify for Nationals?  No Problem, buy an annual license, race one of our XC events, finish top 15 in your category and class, then we take care of the rest...it’s that easy!  USA Cycling Qualification Guide
