Pneumatic tire having a rubber component containing a tin/amino functionalized rubber and an inversion carbon black

A pneumatic tire having a rubber component made from a rubber composition comprising:

• (A) a copolymer rubber of a conjugated diolefin and an aromatic vinyl compound, wherein
• (1) the content of amino groups bound to the rubber (nitrogen content value) is 0.0025 to 0.20 mmol/g of copolymer rubber;
• (2) the content of the polymerization units of the aromatic vinyl compound is from 5 to 50 weight percent based on the copolymer rubber,
• (3) the content of vinyl bonds in the polymerization unit of the conjugated diolefin (the total content of a 1,2-bond and a 3,4-bond) is from 50 to 90 mol percent or more based on the polymerization unit of the conjugated diolefin;
• (4) at least 40 percent of the polymerization end terminals of the copolymer rubber is modified or coupled with a tin compound;
• and
• (5) the molecular weight distribution is polymodol;
• and
• (B) from 10 to 150 phr of an inversion carbon black having the properties a particle size distribution curve with an absolute slope of less than 400,000 nm3, the absolute slope AS being determined from measured aggregate size distribution using the following formula:
• 3 AS = ∑ i = 1 k ⁢ ( H i ⁢ ( x i - x _ ) ) 3 ∑ i = 1 k ⁢ H i
• wherein H1 denotes the frequency at which the particle diameter X1 occurs and x is the particle diameter of the aggregate, whose weight corresponds to the average particle weight of the carbon black aggregate, the summation being carried out in the range of 1 to 3000 nm in equidistant spacing for each nanometer
