examples

[0061]The present invention is more specifically described with reference to examples of tires for passenger vehicles with a TOS structure, but the present invention is not limited to these examples.

Preparation of Terminal Modifier

[0062]A measuring flask (100-mL) was charged with 23.6 g of 3-(N,N-dimethylamino)propyltrimethoxysilane (AZmax. Co.) in a nitrogen atmosphere, and was further charged with anhydrous hexane (Kanto Chemical Co., Inc.) to thereby prepare a terminal modifier in a total amount of 100 mL.

Copolymer Preparation 1

[0063]A sufficiently nitrogen-purged, pressure-resistant vessel (30-L) was charged with 18 L of n-hexane (Kanto Chemical Co., Inc.), 2000 g of butadiene (Takachiho Trading Co., Ltd.), and 2 mmol of tetramethylethylenediamine (Kanto Chemical Co., Inc.), and then the temperature was raised to 60° C. Next, 10.3 mL of butyllithium (Kanto Chemical Co., Inc.) was added to the mixture, and then the temperature was raised to 50° C., followed by stirring for three hou

Abstract

The present invention provides a pneumatic tire having an excellent finished bonding surface between the tread and its adjacent wing or sidewall while maintaining required performance of a tire such as abrasion resistance and resistance to degradation over time. The present invention relates to a pneumatic tire including a tread and a wing or sidewall adjacent to the tread, wherein the tread is formed from a rubber composition for a tread which has a specific net sulfur content derived from crosslinking agents; the wing or sidewall is formed from a rubber composition for a wing or sidewall which has a specific net sulfur content derived from crosslinking agents; and a specific relationship is satisfied between the net sulfur content derived from crosslinking agents in the rubber composition for a tread and the net sulfur content derived from crosslinking agents in the rubber composition for a wing or sidewall.
