Big Boat - 26x4.0" Black/Tanwall

The CST Big Boat 26x4.0" Tire brings smooth-rolling confidence to any fat bike adventure. With its generous volume and smart tread pattern, this tire offers a balance of grip and efficiency that keeps you afloat on sand, snow, and loose terrain—without feeling sluggish on pavement. The classic black and tanwall design adds a timeless touch that looks just as good on a vintage-inspired cruiser as it does on a modern fat bike build.

Built for riders who want to explore beyond the pavement, the Big Boat delivers a stable, comfortable ride with plenty of traction when the trail gets unpredictable. While not specifically e-bike rated, it’s durable enough to hold its own under the added torque of pedal-assist bikes.

Key Features:

• Large 26x4.0” volume provides excellent floatation and shock absorption on variable terrain.
• Fast-rolling tread design keeps you moving efficiently on both hardpack and soft surfaces.
• Classic tanwall styling adds visual appeal to any fat bike setup.
• Compatible with standard and e-bike applications for versatile use.

From snowy morning commutes to sandy shoreline rides, the CST Big Boat keeps the adventure rolling smoothly and in style.
