IRC Boken Pro 700x47 Tubeless Gravel Tire | Tan Wall | 120 TPI
IRC Boken Pro 700x47 Tubeless Gravel Tire | Tan Wall | 120 TPI
Fast on pavement. Confident on gravel. Big-volume 47mm performance for modern gravel bikes.
The IRC Boken Pro 700x47 is a high-performance gravel tire designed for riders who want to move quickly across mixed surfaces without giving up the traction and volume needed when the pavement ends.
Its tread design combines a fast-rolling, smooth center section with micro-knurled shoulder knobs. The center minimizes rolling resistance on pavement and hard-packed gravel, while the textured shoulders provide additional grip as surfaces become loose or the bike is leaned into a corner.
At 700x47, the Boken Pro provides substantially more air volume than narrower traditional gravel tires, allowing riders to take advantage of lower pressures for additional traction, comfort, and control. A supple 120 TPI casing helps maintain responsive ride quality, while the tubeless-ready construction makes it an excellent match for today's high-performance gravel wheelsets.
This version features a distinctive black tread with tan sidewalls for a premium look that pairs particularly well with modern carbon gravel bikes.

Built for Fast Mixed-Surface Riding
The Boken Pro is particularly well suited to gravel routes where the surface constantly changes. Its relatively smooth center section rewards riders on pavement, hardpack, and fast dirt roads without requiring them to give up the additional traction of a purpose-built gravel tire.
As conditions become looser, the micro-knurled shoulder tread provides additional bite for cornering and bike control. This makes the Boken Pro an excellent option for riders whose gravel rides include significant stretches of pavement between dirt sectors.
Why Choose a 47mm Gravel Tire?
A wider gravel tire allows greater air volume and can typically be ridden at lower pressure than a narrower tire. When properly matched to the rider, rim, and terrain, that additional volume can improve:
- Comfort over rough gravel and broken pavement
- Traction on loose surfaces
- Cornering confidence
- Control over rocks, washboard, and uneven terrain
- Resistance to impacts compared with excessively high tire pressures
For modern gravel bikes with generous tire clearance, a 47mm tire can deliver an excellent balance between speed and off-road capability.
Tubeless Ready & Hookless Compatible
The IRC Boken Pro features a tubeless-ready folding casing and is designed for compatibility with modern gravel wheel systems, including appropriate hookless rims.
A properly installed tubeless setup allows riders to run lower pressures for improved grip and comfort while also allowing sealant to automatically seal many small punctures encountered during gravel riding.
