Bridgestone published third-generation RFT technology

A few days ago, Bridgestone has finally released their third generation RFT technology.RFT Run Flat Tire is a tire wall reinforced tires and the birth of its first-generation product in 1987, due to the tire wall thickening and strengthened in order to achieve the tire in case of lack of air is still safe to travel for a range requirements,vehicles, the occupants will be harder than the average tire Lang. Since 2005, with the tire wall reinforced rubber improved so that better comfort when driving, creating the second generation of the thickened tire, first-generation RFT can be said with experimental technology is a to the second generation of the RFT, began a large-scale practical propulsion, among the more well-known products include the Potenza RE050A RE070R However, although the second-generation products in the sidewall of the tire hardness decreased, even when used with rubber and tread design of higher technology, is bound in a state of comfort and ultimate grip aspect of something missing. The third generation of Run Flat Tire with a newer technology, to reduce the radial stiffness, with the ride comfort without losing the general tire. The new technology can also be used to develop a variety of high aspect ratio tires, but not confined to the low flat rate of movement of the tire.

Comparison of each generation Comfort

Usually the rigidity of the tire is indicated by 100 and carried generations RFT technology for comparison. The parameter is the less comfort Vietnam

High (tire size 245/40R18 93W. Compared to the third generation with a new reinforced rubber and the Fetus.

Third generation RFT Technical Summary

The design of the third generation RFT's core theme is to "control the heat. The tire wall strengthening type Run Flat Tire, if you want to enhance its comfort, then, the most effective method is to rubber-thinning and softening sidewall when the tire impact buckling movement of the tire wall so that heat generated increases. The durability (lost air pressure after the durability) to maintain and improve driving comfort improvement phase both at the same time, handle heat to become the biggest problem. Resolve this issue, Bridgestone use of three new development concept to be realized: First, the development of a new type of tire wall rubber; thermal characteristics and inhibit the deformation of the novel Taigu; Third, help tire wall cooling Cooling Fin technology. The effect of these three technologies to improve driving comfort, therefore, the most appropriate balance then reality based on the weight of the vehicle, the practical effect of automobile commercialization respective.

(1) relieve the fever of the new rubber sidewall reinforcement

"Nano Pro-Tech" technology can make a new tire wall carbon reinforced rubber molecules to form a more dispersed distribution of the friction between the carbon molecules will be reduced when the tire is giving pressure, inhibit fat calories fundamentally generation. Using this technique, the third generation RFT compared with the second generation, heat will be reduced to half of the original.
