Breaking Industry Technical Barriers | 650-15 LT Bias Light Truck Tire, J-Speed Rating Achieved!

Common Issues of Traditional Bias Light Truck Tires

Light truck fleets and drivers often face performance flaws with bias tires for heavy-load, high-temperature and rough-road operations.

Most conventional bias tires prioritize load capacity and wear resistance, yet their speed is limited to 60-80 km/h, unfit for high-speed travel. High-speed alternatives, by contrast, feature poor load capacity and pose major safety risks when fully loaded.

The 650-15 is a practical yet niche size. In the domestic market, bias light truck tires of this size rated for J-speed (100 km/h) are extremely scarce, a long-standing industry problem.

Why J-Speed (100 km/h) Is Hard to Achieve for Domestic Bias Tires

Different from radial tires, bias tires adopt cross-cord construction, ideal for heavy loads and rough roads but weak in heat dissipation and high-speed stability. They tend to deform, overheat and delamate at high speeds, resulting in bulges and blowouts.

This poses huge technical challenges. Major manufacturers focus on mainstream radial tires, as niche sizes like 650-15 demand high R&D costs with low returns. Smaller factories lack advanced equipment, R&D strength and mature techniques to produce J-speed bias tires.

Our Technical Breakthrough for 650-15 LT Bias Light Truck Tire

Our R&D team optimized cord angles, plies and lamination processes, upgraded heat-resistant high-toughness rubber compounds, and completed rigorous tests under extreme conditions. We finally launched this J-rated 650-15 LT bias tire.

It works perfectly for urban & rural cargo delivery, construction transport, mountainous rough roads and high-speed driving in hot areas.

Key Advantages

Higher Speed

Rated J-speed with a maximum safe speed of 100 km/h. It solves the industry dilemma: no high speed with heavy loads, no safe loads at high speed.

Superior Load & Impact Resistance

Reinforced carcass and tire shoulders greatly improve compression, impact and deformation resistance. The tire stays stable under full loads to avoid uneven wear and bulges.

Improved Overall Stability

Optimized tread and shoulder rubber formulas with heat and cut-resistant additives. It resists heat fade on long hot journeys and withstands cuts and impacts on tough roads, extending service life effectively.

FAQ

1.What is the warranty period and service life of this tire?

Warranty period: 12 months. With proper use, the service mileage ranges from 40,000 to 60,000 kilometers.

2.Are there any special installation or usage requirements compared to ordinary bias tires?

Generally consistent. Ensure strict matching of rim specifications and rated air pressure during installation, perform dynamic balance correction before first use, and avoid severe overloading.

3.What maintenance advice do you have for long-term use under heavy-load, high-speed, and rough-road conditions?

Regularly check tire pressure and tread, and avoid rapid acceleration/braking.

4.Do you offer bulk purchase or fleet cooperation services?

Yes. We provide price discounts and technical support for bulk orders from fleet customers.
