We obsess over suspension travel, frame geometry, brake power, and drivetrain efficiency. And rightly so, these are incredible feats of engineering. But at the end of the day, all that technology, all that power, all that control funnels down to two small patches of rubber that are actually touching the dirt. Your tires are the ultimate interface between you, your bike, and the mountain. Today we'll dive into what makes the tires of your mountain bike an engineering masterpiece.
