The most-asked question in the gravel community. At what point does wider become too wide, and when does it become the smart choice? This infographic compares the four most common gravel tire widths against rolling resistance, comfort, pinch-flat risk, and terrain suitability.

Key insight: 45mm has become the new minimum for mixed-surface riding. It is the width where comfort gains outpace rolling resistance penalties for most riders on real-world gravel.

The comparison is built from ETRTO tire/rim compatibility data, published rolling resistance numbers, and real-world ride feedback from gravel racers and tourers.
