    Abstract: The invention presents a device and a method for placing and attaching a strip inside a tire. Specifically, the tire is positioned on a mounting in relation to a centering means, and an adhesive device is placed inside the tire. While the tire is rotated, the strip is moved inside the tire, wherein a pressure force is applied to said strip. The strip is driven at a linear speed greater than the rotation speed of the tire, thus producing an effect of compressing said strip, the length of which becomes less than the nominal length thereof, thus creating a space between both ends of the strip such that, after release, the strip scrapes the adhesive device, which is repositioned on said ends, thus simultaneously causing said ends to be attached end to end.

    Abstract: The present invention aims to provide a rubber composition for tires that can improve processability, crack resistance, ozone resistance, discoloration resistance, and tire appearance while maintaining a good balance between them, and also to provide a pneumatic tire formed from the rubber composition. The present invention relates to a rubber composition for tires, containing: a rubber component; an antioxidant; and polyether, the rubber component having a combined content of polybutadiene rubber, natural rubber, and polyisoprene rubber of 80% by mass or more per 100% by mass of the rubber component, the rubber composition containing the antioxidant in an amount of 0.3 to 7.0 parts by mass per 100 parts by mass of the rubber component, the polyether having an average mass content of at least two consecutive polyethylene oxide units of 85% or less of the polyethylene oxide mass content of the polyether.
