GT Radial SportActive Performance Tire (245/40 R17 91Y)

GT Radial SportActive Performance Tire (245/40 R17 91Y)

The GT Radial SportActive is a high‑performance summer tire engineered for drivers who demand exceptional grip, precise handling, and reliable performance across a wide range of road conditions. Designed with the latest radial construction technology, this tire delivers consistent traction on both wet and dry surfaces while maintaining durability and comfort over long distances.

Key Technical Specifications

• Tire Size: 245/40 R17 91Y – a standard dimension that fits most compact to mid‑size vehicles, offering an optimal balance between width, aspect ratio, and wheel diameter.
• Construction Type: Radial (R) – ensures superior sidewall flexibility for improved ride comfort and reduced rolling resistance.
• Speed Rating: Y – approved for speeds up to 300 km/h (186 mph), making it suitable for high‑speed driving on highways and performance vehicles.
• Tread Depth: 7.5 mm (typical for summer tires) – provides ample contact area for maximum grip while maintaining a smooth ride.
• Load Index: 91 – capable of supporting up to 615 kg per tire, suitable for passenger cars and light SUVs.
• Tire Type: Summer (Pneumatici estivi) – optimized for warm weather conditions with a tread pattern that expels water efficiently to reduce hydroplaning risk.
• Label Information: C B 71dB – indicating the tire’s performance in terms of wet grip (C), rolling resistance (B), and noise level (71 dB).

Tread Design & Performance Features

The GT Radial SportActive incorporates a multi‑directional tread pattern that enhances cornering stability by directing water away from the contact patch. The tread blocks are engineered to flex during lateral loads, providing excellent grip on both dry asphalt and wet roads.

• Water Evacuation: Deep circumferential grooves channel water efficiently, reducing the risk of hydroplaning even at high speeds.
• Grip Enhancement: The tread blocks feature a unique micro‑texture that increases friction on wet surfaces without compromising dry traction.
• Noise Reduction: Advanced tread geometry minimizes sidewall vibrations, resulting in a quieter driving experience.

Construction & Materials

The tire’s radial construction uses high‑modulus steel belts that provide structural integrity while allowing the sidewalls to flex. This design reduces rolling resistance and improves fuel efficiency. The outer tread compound is formulated with silica additives, enhancing wet grip and reducing wear.

• Steel Belts: High‑strength steel layers for load distribution and stability.
• Silica‑Enhanced Compound: Improves traction on slick surfaces and extends tread life.
• Sidewall Design: Reinforced with a flexible polymer layer to absorb road irregularities, delivering a smooth ride.

Ideal Vehicle Applications

The GT Radial SportActive is tailored for a wide range of passenger cars and light SUVs that require reliable summer performance. Its dimensions and load rating make it compatible with models such as:

• Compact sedans (e.g., Volkswagen Golf, Ford Focus)
• Mid‑size family cars (e.g., BMW 3 Series, Mercedes‑C Class)
• SUVs and crossover vehicles that fit a 17” wheel size.

Installation & Maintenance Tips

To maximize the lifespan and performance of the GT Radial SportActive:

• Proper Inflation: Maintain the recommended pressure as specified in your vehicle’s owner manual to ensure even tread wear.
• Tire Rotation: Rotate every 10,000 km (or as advised by the manufacturer) to promote uniform wear across all four tires.
• Alignment Checks: Perform wheel alignment checks annually or after any significant impact to maintain optimal handling.
• Tread Inspection: Regularly inspect tread depth; replace when it falls below 3 mm for safety compliance.

Why Choose GT Radial SportActive?

The combination of a robust radial construction, advanced tread design, and high speed rating makes the GT Radial SportActive an excellent choice for drivers who prioritize performance without sacrificing comfort. Its ability to deliver consistent traction in both wet and dry conditions ensures confidence on highways, city streets, and winding roads alike.

Conclusion

The GT Radial SportActive (245/40 R17 91Y) stands out as a premium summer tire that merges cutting‑edge technology with everyday practicality. Whether you’re navigating urban traffic or cruising on the open road, this tire offers the grip, stability, and durability needed for a safe and enjoyable driving experience.
