About Accelera PHI 255/30 R21 95W

The Accelera PHI is a performance-oriented tyre featuring a dynamic medium lateral groove, straight medium rib and dedicated shoulder blocks. Accelera states that these features are designed to improve wet handling and rolling resistance, dry-road stability and flexibility, while the shoulder blocks support cornering stability and noise reduction.

Tread Design and Steering Response

The straight medium rib provides a stable central tread area and supports steering response and flexibility on dry roads. The shoulder blocks are designed to improve stability when cornering and manoeuvring, making the PHI suitable for performance-oriented passenger cars.

Dry Road Performance

The wide 255 mm footprint and low 30-series profile are designed to provide a direct connection with the road and responsive steering behaviour. The reinforced XL construction provides the additional load capacity associated with this specification.

Wet Road Performance

Its tread layout helps move water through the contact area, supporting grip and stability on wet paved roads. Actual braking and traction performance depend on road conditions, tyre pressure, vehicle condition and driving style.

Cornering and Highway Stability

The shoulder block design supports cornering stability, while the low-profile 21-inch configuration is intended for drivers who prioritise steering response and road stability. The W speed rating provides capability for high-speed road use within the applicable conditions.
