The Bridgestone RD630 summer tire was specifically designed for light commercial vehicles, primarily operated on asphalt roads. One of the key features of this model is the combination of handling, high driving comfort, and a very long service life. Also, the successful selection of the size range cannot be ignored. Despite consisting of only 6 sizes for wheels with a mounting diameter of 15 and 16 inches, this model has excellent applicability, making it possible to install it on most modern minivans and light trucks.
Low Noise Level
As mentioned earlier, this tire has a very high level of driving comfort, one of the signs of which is low noise and vibration. This was achieved due to a number of features of the tread pattern. It contains a relatively small number of individual elements by today's standards. In addition, they are grouped into separate longitudinal ribs and are located with a different pitch relative to each other. This made it possible to significantly reduce the level of resonant noise and vibration that occurs during movement.
Dual-Layer Tread
Another feature of this tire is a tread consisting of two layers of rubber compound with different characteristics. The lower layer is made of a more rigid composition, which has high deformation resistance, thanks to which the tire has excellent handling. The upper layer of the rubber compound has increased elasticity, which allows the tread to dampen most of the irregularities on the road surface. As a result, the tire demonstrates a very soft and comfortable ride, surprisingly combined with good handling.
Instant Response to Steering
The tread pattern of this tire consists of four longitudinal ribs - two central and two shoulder zones. The latter are very rigid tread elements that, among other things, have massive sizes. Thanks to this, this part of the tread is practically not affected by the dynamic deformation that occurs during movement. This allows the tire to respond almost instantly to steering, making the process of controlling a heavy vehicle a simpler task. In other words, the tire literally "follows the wheel", unconditionally executing all the commands of the driver.
Long Service Life
Like any tire designed for commercial vehicles, the RD630 has a very long service life and reduced rolling resistance. The main credit for this goes to the tread pattern and rubber compound. As mentioned earlier, the tire's tread Bridgestone RD630 contains a relatively small number of individual elements, which are essentially four-sided blocks located in its central part.
Reducing the size of the tread elements made it possible to make them as large as possible, which significantly improved the distribution of external weight on the contact patch. As a result, the tire's tread wears evenly. This process was significantly slowed down due to the inclusion of special components in the rubber compound that improved the tread's resistance to abrasive wear.
Excellent Resistance to Aquaplaning
Among the many advantages of the RD630, it is impossible not to mention the excellent grip on wet roads, largely ensured by the open design of the central part of the tread pattern. It is here that the main components of the drainage system are located - three longitudinal grooves connected to each other by a system of transverse channels. Their sizes are large enough to handle the removal of almost any amount of water from the contact patch, thanks to which the tire avoids the effect of aquaplaning even when moving at high speeds.
Main Features of the Bridgestone RD630 Tire
- low noise and vibration level due to the carefully calculated placement of all tread elements;
- soft ride provided by a dual-layer tread made of a rubber compound with different characteristics;
- high load capacity and resistance to uneven wear due to the massive size of the tread elements and optimal distribution of external weight on the contact patch;
- excellent traction properties, especially on wet asphalt, thanks to the block structure of the central part of the tread pattern;
- excellent handling ensured by the rigid construction of the shoulder zones;
- high resistance to aquaplaning due to the open design of the central part of the tread pattern, which contains many longitudinal and transverse drainage channels;
- low rolling resistance, thanks to the reduced number of tread elements, grouped into four longitudinal ribs.
