Accelera Iota ST68 275/50R21XL 113V BSW (2 Tires)

The Accelera Iota ST68 is an all-season ultra-performance tire. This tire is designed to deliver unmatched stability and quick steering responsiveness. It also offers extended tire life and comfortable rides.

Engineered with modern SUV fitments in mind, it offers strong stability, wet-road performance, and long-wear value. 

Its tread design features three interlocked block lanes to enhance directional stability and quick steering response, while wide main grooves clear water efficiently to reduce the risk of hydroplaning. Ramp-shaped “exclamation” sipes break thin layers of water during wet conditions and promote enhanced grip. Built to support heavier loads often associated with SUV or crossover usage, the Iota ST68 offers a smooth ride, consistent performance and a strong value proposition.

Best-suited for: Light Trucks, SUVs, and CUVs.

Tire Features:

• Three interlocked block lanes offer directional stability and quick steering responsiveness.
• Main grooves clear water from the surface and prevent hydroplaning.
• Exclamation sipes prevent hydroplaning and deliver traction in wet weather conditions. Unique tread pattern boosts grip on tough road conditions.
