As a part of a series of previous studies, physical properties of various portions of a tire made of NR-Syn. R bloods were studied. 1. It was found, in general, most effective for tire tread when 50 parts of HAF black was blended with NR and Syn. R with a ratio of 70/30. 2. It was found that the use of SBR 1712 has an advantage in price, easy processing and physical properties than other synthetic rubber. 3. A technical compounding of various portions of a tire has to be determined for optimum cure conditions.
