About Accelera 285\40 R22 110Y IOTA ST68 2024

Tyre Size and Fitment

The 285/40ZR22 specification features a 285 mm nominal section width, a 40% aspect ratio and a 22-inch wheel diameter. Accelera's technical data lists an actual section width of approximately 290 mm, an overall diameter of 787 mm and a 10.0-inch measuring rim. The XL construction provides reinforced load capacity for compatible applications.

Load and Speed Rating

The 110 load index corresponds to a maximum rated load of 1,060 kg per tyre. The Y speed rating permits speeds of up to 300 km/h under the applicable operating conditions. Together with the XL construction, this specification is intended for larger SUVs and performance-oriented vehicles requiring a high load and speed rating.

Dry-Road Performance

The IOTA ST68 uses an asymmetric, road-focused tread design developed for SUV applications. Its three interlocked tread-block lanes are designed to provide directional stability and quick steering response, helping maintain controlled handling during acceleration, cornering and braking on paved roads.

Wet-Road Performance

The tyre incorporates main grooves designed to clear water from the contact area, while its exclamation-shaped sipes are designed to break through thin layers of water and maintain traction in wet conditions. The exact 285/40ZR22 110Y XL version carries a C rating for wet grip.

Steering and Cornering

The combination of a wide contact area, low 40-series profile and reinforced XL construction gives the IOTA ST68 a performance-oriented road character. The interlocked tread-block lanes are designed to support directional stability and responsive steering, making the tyre suitable for drivers who prefer precise road behaviour.

Highway and SUV Use

The IOTA ST68 is designed specifically around modern SUV applications. Its road-oriented tread pattern is intended for paved surfaces, including city roads and highways, while the tread layout balances steering response with everyday driving comfort.

Comfort and Road Noise

Accelera describes the IOTA ST68 as being engineered for comfortable driving and extended tyre life. The exact 285/40ZR22 version has an external rolling-noise value of 68 dB and noise class A under the available European tyre-label data.

Summer and Year-Round Positioning

Production Year

This product is specified as a 2024 production-year tyre. The actual manufacturing date of an individual tyre should always be confirmed from its DOT or sidewall date marking before installation.
