More Information
Summary:Tire treads and tires having such tire treads are included, such treads manufactured with a rubber composition that includes mostly, if not entirely, a polybutadiene rubber having cis-1,4 bond content of at least 95%. The rubber composition further includes between 60 phr and 95 phr of a plasticizing resin having a Tg of at least 25° C. and between 0 phr and 15 phr of a liquid plasticizer. Additionally the rubber composition is reinforced with at least 90 phr of a silica reinforcing filler. Alternatively, in some embodiments, the rubber composition may be reinforced with an organic filler, an inorganic filler or combinations thereof. In some of these embodiments, the rubber composition includes at least 90 phr of such reinforcing filler.
