According to GlobalData’s company profile on Goodyear Tire & Rubber, Anti-skid tyre treads was a key innovation area identified from patents. Goodyear Tire & Rubber's grant share as of January 2024 was 75%. Grant share is based on the ratio of number of grants to total number of patents.
A recently granted patent (Publication Number: US11884823B2) discloses a pneumatic tire design that incorporates a unique vulcanizable rubber composition. The composition includes specific proportions of low Tg functionalized solution polymerized styrene-butadiene rubbers with distinct glass transition temperatures (Tg1 and Tg2), ensuring a balance of properties. The rubber composition excludes a homopolymer of butadiene and incorporates additional styrene-butadiene rubber, silica, hydrocarbon resin, and oil in specified amounts.
Furthermore, the patent claims highlight variations in the glass transition temperature differentials (Tg2-Tg1) within the rubber composition, with specific embodiments requiring a minimum difference of 10° C but less than 30° C. The claims also specify the end-functionalization of the first and second functionalized styrene-butadiene rubbers, along with the additional styrene-butadiene rubber. These features contribute to the overall performance and characteristics of the pneumatic tire, with some embodiments requiring a Tg2-Tg1 difference of at least 15° C or 20° C. Overall, the patented pneumatic tire design aims to enhance tire performance, durability, and efficiency through the precise combination of rubber components and additives as outlined in the granted claims.
