Tires are your bike’s only contact point with the trail. Their performance and design can have a large impact on the quality of your ride. Back in 1996 Keith Bontrager designed his first tire tread in an effort to improve traction during harder rides. Over the past decade, Bontrager has developed a comprehensive lineup of mountain tires, today producing a selection of tires suitable for just about any condition you’ll find out on the trail.

Tire designs don’t just fall from trees. They go through a stringent concept phase before our computer aided design group takes over. Here the tire tread concepts are analyzed and tweaked down the very edges of each knob. While the tread is in design phase the Tire carcass/construction features and tread compound are chosen for each tire to help ensure optimal tire performance. The two are then mated on computer and another process of tweaking and analyzing occurs. Along the way graphics designers prepare a visual presentation on the tire that mates well with your mountain bike wheels. Finally the tire goes through a comprehensive testing phase before speeding you down the trail. | 02 |
