About Bridgestone315\35 R20 Dueler H/P Sport RFT

The Dueler H/P Sport RFT is a performance-oriented SUV tyre developed to combine responsive steering, high-speed stability, wet and dry road performance and driving comfort. Bridgestone describes the tyre as offering highly responsive steering, excellent high-speed stability, a comfortable ride and wet-road performance. The tread incorporates a silica compound, wide shoulder blocks and an advanced tread pattern, while the reinforced Run Flat construction allows limited continued mobility after a loss of air pressure.

315/35 R20 Tyre Size

The 315/35 R20 designation identifies a nominal tyre width of 315 mm, a 35-series aspect ratio and radial construction for a 20-inch wheel. The low-profile 35-series sidewall is designed to support responsive handling and cornering characteristics. For this specification, the overall diameter is approximately 28.7 inches, with a section width of approximately 12.6 inches.

110W Load and Speed Rating

The 110 load index corresponds to a maximum rated load of 1,060 kg per tyre. The W speed symbol indicates a maximum rated speed of 270 km/h. These ratings should be compatible with or exceed the vehicle manufacturer's specified tyre requirements, particularly when the tyre is installed on a high-performance SUV.

XL Construction and Run Flat Technology

This 315/35 R20 specification is an XL tyre and uses Bridgestone Run Flat technology. The reinforced construction is designed to support the vehicle for a limited distance after a loss of air pressure, allowing the driver to reach a suitable location for inspection or repair without an immediate tyre change. Run Flat operation must remain within the manufacturer's specified speed, distance and vehicle-system limitations.

Asymmetrical Tread Design

The Dueler H/P Sport uses an asymmetrical tread design with different tread zones working together to support handling, stability and traction. Wide shoulder blocks contribute to cornering grip, while the advanced tread pattern is designed to support steering response and provide a balanced contact footprint during performance-oriented road driving.

Handling and Steering Response

Responsive steering is one of the main characteristics of the Dueler H/P Sport. The tread structure, reinforced construction and wide shoulder areas are designed to provide controlled directional response and stability during cornering and lane changes. Bridgestone also identifies highly responsive steering and excellent high-speed stability among the tyre's key characteristics.

Wet-Road Performance

The silica tread compound is designed to provide consistent handling on wet roads, while the tread pattern helps manage water across the contact area. Bridgestone positions this tyre for wet and dry performance, and the European tyre label for this specific 315/35 R20 110W RFT specification gives it a B rating for wet grip.

Summer Performance

The 315/35 R20 110W Dueler H/P Sport RFT is classified as a summer tyre. It is designed primarily for warm-weather road use and performance-oriented driving rather than severe winter conditions. This specification does not carry the 3PMSF marking and should not be treated as a dedicated winter tyre.

Comfort and Road Noise

Although the Dueler H/P Sport is designed for performance-oriented SUVs, Bridgestone also focuses on ride comfort and refinement. The manufacturer describes the tyre as providing a comfortable ride, while the European specification for this size records an external rolling noise level of 71 dB.

Rolling Resistance and Wet Grip

The EU tyre label for the 315/35 R20 110W RFT specification indicates an E rating for fuel efficiency and a B rating for wet grip, with external rolling noise measured at 71 dB. These EU label classifications are separate from the UTQG system and should not be converted or treated as equivalent ratings.

UTQG Performance Rating

The available specification data for the Dueler H/P Sport RFT 315/35 R20 110W lists a UTQG rating of 300 A A. This represents a treadwear grade of 300, traction grade A and temperature grade A. UTQG ratings are a separate North American tyre-rating system and are not directly interchangeable with European tyre-label classifications.

BMW OE Marking

The 315/35 R20 110W RFT specification is listed with BMW * OE marking. The star marking identifies the tyre as an OE-approved specification associated with BMW applications. Vehicle compatibility should still be confirmed using the vehicle's exact recommended tyre size, axle position and load/speed requirements.

Production Year

This product listing specifies 2024 as the requested production year. The production year refers to the intended manufacturing year of the supplied tyre, while the exact production week should be verified from the DOT or applicable date code on the individual tyre sidewall.

Who Should Consider This Tyre?

The Bridgestone Dueler H/P Sport RFT 315/35 R20 110W is suited to drivers of compatible premium SUVs, CUVs and 4x4 vehicles who require a wide, low-profile summer tyre with XL construction, Run Flat capability, a 1,060 kg per-tyre load rating and W-speed performance up to 270 km/h. Its BMW * OE marking also makes this specific specification relevant to compatible BMW applications requiring this tyre configuration.
