“…The low dissipation factor obtained was the remarkable output of the study [ 72 ]. Fernandes et al developed tyre tread compounds with reduced rolling resistance and improved wet grip resistance using modified rice husk ash in a green perspective [ 73 ]. Fang et al have prepared a high-performance rubber composite by introducing the urazole groups into the NR chain backbone.…”

Growing natural calamities as a consequence of global warming are one of the most pondering subjects today. The exponential growth of environmental pollution due to unscientific human exploitation of natural resources is considered the prime reason for the harsh responses of nature. Researchers from various fields of industry and academia are working hard to develop and implement products/technologies that are environmentally friendly or less harmful to the ecosystem. Material researchers, specifically those working in the automobile sector are also not behind in search of green products from eco-friendly raw materials and production methods. The automobile industry is collectively responsible for around 40% of global pollution in terms of greenhouse gas emissions. Out of which around 20–30% is originating from tyre production and its end-use. In this view, tyre production from eco-friendly raw materials and technologies that have minimum hazardousness to the environment is a hot research topic today. A few products in the market with “green” tags and many are in the pipeline for the recent future. This review summarises a detailed discussion of the emerging green technologies for tyre production and depicted comprehensive data from the available literature. The paper has been drafted from a well-balanced academic and industrial point of view since the researchers from both sectors are working in harmony for a better future for green tyre technology.

“…The three most important parameters are lower rolling resistance and better wear and wet grip performance. 43,44 Generally, low tan d (damping/loss factor) value in the 50-80 C temperature range means low rolling resistance and better fuel saving. The damping parameter at high temperatures gives information about the suitability of the rubber composite for use as a tread in the tire and the rolling resistance of the tire.…”

In this work, the effects of using feldspar (FLD) as an alumina-silicate inorganic filler, with carbon black (CB) as a novel binary filler system, on the properties of SBR compounds were investigated for tire applications. The bis(triethoxysilylpropyl) disulfide (TESPD) was used for modification of FLD. The SBR hybrid composites were produced by replacing 10 phr of CB filler with neat FLD and functionalized FLD (F-FLD). The TESPD was added directly to the rubber mixture including neat FLD. The SBR composite which has only CB filler (50CB) was found to have the highest damping parameter (tan δ) value at 60°C. On the other hand, the composites loaded with the CB and the FLD fillers exhibited relatively lower tan δ at the same temperature showing lower rolling resistance meaning better fuel saving performance. The lowest rolling resistance was achieved for the 40CB-10F-FLD most probably due to its stronger interaction with the SBR elastomer molecules through the silane agent-assisted crosslinks of the F-FLD. As another dynamic property, the storage moduli at −20°C were found to be lower for the SBR hybrid composites as compared to that of the 50CB composite, exhibiting enhanced winter traction performance of the composites having FLD filler together with CB. The composites containing only 10 phr of FLD and F-FLD, on the other hand, exhibited very low tensile strength values which are not acceptable for tire tread materials.

“…[4][5] Fillers have an important role in tire tread compounds. [5][6][7] This is illustrated by the use of hybrid system filler based on carbon black (CB) and silica, introduced by Michelin in 1993. This innovation is known as green tires due to its remarkable reduction of fuel consumption.…”

“…Synthetic layered silicate, Magadiite, did not show similar wet traction and rolling resistance performances compared to silica in SBR tire tread compounds. 13 Natural fillers were also already tested, for example, rice husk ash/CB 7 and microcrystalline cellulose hybridized with nanosilica. 14 According to Fernandes et al, 7 the rice husk ash worked as nonreinforced filler, and although it showed an reduction of rolling resistance, the abrasion resistance was not suitable.…”

Carbon black and high performance silica have been widely employed as binary system filler in tire tread formulations. This study evaluated the total and partial substitution of silica by metakaolin (MK) on the properties of tread rubber composites. Dynamic mechanical thermal analysis and abrasion tests were conducted as typical assessments of tire tread performance: rolling resistance (fuel consumption), wet traction (safety), and abrasion (durability). Further the energy spent by the equipment during the processing of formulations was also analyzed, as well as rheological and mechanical properties. A significant reduction of rolling resistance was obtained with 75% and 100% of silica substitution by MK, which could lead to lower heat buildup in tire tread applications, without showing negative effects on wet traction, although abrasion showed undesired results. The substitution of silica by MK also lowered energy demanded for processing. No major changes were observed in vulcanization parameters and mechanical properties, which is interesting considering the fact that MK is nonreinforce filler.
