Your tire choice can completely transform your ride. That’s why we have been obsessed with tires since 1974. Did you know, our first product ever, was a tire? The Specialized Touring Tire launched in 1976. From the feel of the road (or trail) to how fast and confident you roll, gravel bike tires are key to your performance. 

Before diving into tread and pressure, there’s one crucial detail: **your bike’s tire clearance—**you can’t run big tires without room for them. That’s why we gave the all-new Diverge 4 clearance for up to 2.2" tires—plenty of space to go wide when the terrain demands comfort and traction, or run narrower rubber for speed on hardpack. Bottom line? More clearance = more options. 

This guide will help you understand how tire volume, tread pattern, and tire pressure impact your ride—and how to pick the perfect gravel tire for your terrain. Then we’ll break down three standout Specialized tires designed for everything from hardpack to rowdy trail.
