Abstract

The present invention is directed to a pneumatic tire comprising at least one component, the at least one component comprising a rubber composition, the rubber composition comprising: at least one diene based elastomer; from 20 to 40 parts by weight, per 100 parts by weight of elastomer (phr), of silica; and from 10 to 25 weight percent of aluminum hydroxide; wherein the composition is self-extinguishing at a temperature of 1000° C., and the composition is exclusive of halogenated paraffins and antimony trioxide.

Claims (13)

1. A pneumatic tire comprising at least one component, the at least one component consisting of a rubber composition, the rubber composition consisting of:

at least one diene based elastomer;

from 20 to 40 parts by weight, per 100 parts by weight of elastomer (phr) , of silica; and

from 12 to 20 weight percent of aluminum hydroxide; and

at least one additive selected from the group consisting of carbon black, sulfur containing organosilicon compounds, sulfur donors, curing aids, activators, accelerators, retarders, oils, resins, tackifying resins, plasticizers, fillers, pigments, fatty acid, zinc oxide, waxes, antioxidants, antiozonants and peptizing agents;

wherein the composition is self-extinguishing at a temperature of 1000° C., and the composition is exclusive of halogenated paraffins and antimony trioxide.

2. The pneumatic tire of claim 1 , wherein the amount of silica ranges from 25 to 35 phr.

3. The pneumatic tire of claim 1 , wherein the at least one component is a ground contacting tread.

4. The pneumatic tire of claim 1 , wherein the at least one component is a sidewall.

5. The pneumatic tire of claim 1 , wherein the at least one diene based elastomer is selected from the group consisting of natural rubber, synthetic polyisoprene, polybutadiene and styrene-butadiene rubber.

6. The pneumatic tire of claim 1 , wherein the rubber composition comprises from 28 to 40 percent by weight of silica.

7. The pneumatic tire of claim 1 , wherein the rubber composition comprises from 28 to 35 percent by weight of silica.

8. The pneumatic tire of claim 1 , wherein the rubber composition comprises from 12 to 15 percent by weight of aluminum hydroxide.
