A pneumatic tire is provided including a multiplicity of land portionsA,B,C,D, andE formed by main groovesextending linearly in the tire width direction partitioning the tread surface, and having a designated mounting direction on a vehicle. Among the multiplicity of land portionsA,B,C,D, andE, lug grooves are not provided in a ground contact region R of the land portionsA andE positioned on both shoulder sides. Lug groovesinclining in the tire circumferential direction that have terminating parts in the land portions and opening to the main grooveon the vehicle inner side are formed at specified intervals in the tire circumferential direction in the land portionsB andD inwardly adjacent to the land portions on both shoulder sides.

The present invention relates to a polyamide resin composition comprising:

Polyamide resin composition having improved weathering resistance and its molded products

Resin composition comprising polyamide resin

A resin composition comprising predetermined amounts of a specific polyamide resin (A), a modified polyphenylene ether resin (B), a fibrous inorganic filler (C) having an average fiber-diameter of 10 .mu.m or less, a powdery inorganic filler (D) having an average particle diameter of 10 .mu.m or less, an epoxy resin (E) and a copper compound (F-1) and/or a powdery phenolic resin (F-2); a molded article formed from the resin composition; and a lamp reflector formed from the molded article. The molded article formed from the above resin composition can give an automotive lamp reflector excellent in resistance to heat generated when a lamp is on, rigidity at high temperatures, clear reflection performance on a mold article surface, adhesion to deposited aluminum and adhesion to a primer coating composition.

Resin composition, molded article and lamp reflector

There is disclosed a polyamide resin composition comprising (A) 100 parts by weight of a polyamide (a) composed mainly of a xylylenediamine component and an .alpha.,.omega.-straight chain asphaltic dibasic acid component, or a combination of the polyamide (a) and polyamide 66, (B) 1 to 15 parts by weight of polyamide 12, (C) 0.01 to 5 parts by weight (in terms of copper) of a copper compound, (D) 1 to 15 parts by weight of carbon black, and (E) an alkali metal halide of such an amount that the number of halogen atoms of the alkali metal halide is 0.3 to 4 per one copper atom of the above copper compound. Said polyamide resin composition has an excellent weather resistance, moldability, and mechanical properties, and can be injection-molded.
