A rubber composition for a tire, in which a specific tackifier is compounded, and tackiness and various physical properties are improved, compared with compounding a petroleum resin or a terpene resin, is provided. The rubber composition for a tire comprising an alkyd resin and a pneumatic tire using the same. It is preferable that a material derived from a resource other than petroleum, particularly, a material derived from animal and/or vegetable, and more particularly, a material derived from an animal oil and/or a vegetable oil is contained in the alkyd resin, and it is preferable that unsaturated polybasic acid is contained in the alkyd resin.

1. A pneumatic tire having a tread or a sidewall formed from a rubber composition for a tire comprising: a rubber component containing a modified natural rubber; andan alkyd resin as a tackifier obtained by blending a polyalcohol, a polybasic acid, and a modifier,wherein said polyalcohol is at least
1. A pneumatic tire having a tread or a sidewall formed from a rubber composition for a tire comprising: a rubber component containing a modified natural rubber; andan alkyd resin as a tackifier obtained by blending a polyalcohol, a polybasic acid, and a modifier,wherein said polyalcohol is at least trivalent alcohol,wherein at least 50% by weight of the rubber component is the modified natural rubber,wherein an acid value of the alkyd resin is 10 to 60 mg KOH/g,wherein a hydroxyl group value of the alkyd resin is 50 to 100 mg KOH/g,wherein a softening point of the alkyd resin is −40 to 30° C., andwherein a number average molecular weight of the alkyd resin is 250 to 5,000 and a weight average molecular weight of the alkyd resin is 450 to 10,000. 2. The pneumatic tire of claim 1, wherein, in the rubber composition, at least 50% by weight of a material derived from a resource other than petroleum based on the alkyd resin is contained in the alkyd resin. 3. The pneumatic tire of claim 2, wherein the material derived from a resource other than petroleum is a material derived from animal and/or vegetable. 4. The pneumatic tire of claim 3, wherein the material derived from vegetable is a material derived from a palm oil and/or a palm kernel oil. 5. The pneumatic tire of claim 1, wherein unsaturated polybasic acid is contained in the alkyd resin. 6. The pneumatic tire according to claim 1, wherein the modified natural rubber is epoxidized natural rubber. 7. The pneumatic tire of claim 1, wherein a number average molecular weight of the alkyd resin is 1,000 to 1,500. 8. The pneumatic tire of claim 1, wherein a weight average molecular weight of the alkyd resin is 900 to 3,000. 9. The pneumatic tire of claim 1, wherein a number average molecular weight of the alkyd resin is 1,000 to 1,500 and a weight average molecular weight of the alkyd resin is 900 to 3,000.
