A distinctive feature of the Bridgestone RD613 Steel commercial tire is its high load-carrying capacity, reliability, and durability. This was achieved due to the reinforced design of the carcass, as well as the design of the tread pattern, which contributes to a more even distribution of external load across the tire structure. However, these are just some of the advantages of this model.
Four continuous ribs
The aforementioned ability of the tread pattern to optimize the distribution of external load across all tire elements is largely ensured by the design. It features four practically equal longitudinal ribs with a continuous structure. The combination of these features gives the tire increased carrying capacity and additional resistance to uneven wear.
Reinforced carcass design
The "Steel" prefix in the name should be taken literally, as this tire contains a lot of steel. In addition to the steel carcass, the two-layer breaker is also made of this material. Due to this "substrate" located directly under the tread, several important operational characteristics are improved - load-carrying capacity, high-speed handling, and fuel efficiency.
Key features of the Bridgestone RD613 Steel tire
- The reinforced carcass design with a steel cord breaker provides increased load-carrying capacity, reduces rolling resistance, improves reliability and stability of traction properties, especially when driving at high speeds and in corners;
- Four equal longitudinal ribs with a continuous structure to a large extent optimize the distribution of external pressure across the contact patch, improve high-speed stability and maneuverability, and reduce fuel consumption;
- The wavy shape of the tread ribs provides the contact patch with numerous traction edges, which increases the effectiveness of the tread when accelerating and braking.
