A method of manufacturing a pneumatic tire with surface fastener according to the present technology includes, while engaging a surface fastener provided with a plurality of first engaging elements and a sheet-shaped protective member provided with a plurality of second engaging elements that engage with the first engaging elements of the surface fastener, disposing the surface fastener in an unvulcanized tire so that a surface on a side opposite that of a surface on which the engaging elements are provided is closely fitted to an inner surface of the tire, and vulcanizing the unvulcanized tire provided with the surface fastener using a vulcanizer equipped with a vulcanization bladder.

Pneumatic tire with surface fastener and method of manufacturing same

To provide a pneumatic tire that can prevent reflective material from falling off and can maintain visibility and fashionability based on the reflective material over a long period of time when providing a decorative portion decorated with a reflective material in a tire side wall and a method for manufacturing the same. The pneumatic tire of the present technology is a pneumatic tire including a decorative portion in a tire side wall decorated with a reflective material, wherein at least one recess is formed in the decorative portion and the reflective material is adhered within the recess.

Pneumatic tire and method of manufacturing the same

A laminated body of rubber layers includes: a resin layer formed from a polyester resin or a polyamide resin; a rubber layer formed from a rubber composition containing a diene rubber; and an adhesive layer disposed between the resin layer and the rubber layer. The adhesive rubber composition contains a modified rubber composition (A) or a modified rubber composition (B) both having a number average molecular weight of 70,000 to 110,000. The modified rubber composition (A) is formed from a modified butyl rubber (1) formed by reacting, with a butyl rubber, a compound having in a molecule a nitroxide free radical that is stable at ambient temperature in the presence of oxygen, a radical initiator, and a co-crosslinking agent. The modified rubber composition (B) is formed by compounding the co-crosslinking agent with a modified butyl rubber (2) formed by reacting the compound and the radical initiator with the butyl rubber.
