The present invention provides a rubber composition for a breaker cushion
suppressing exothermic heat and lower of rubber properties and a tire
using the same. A rubber composition for a breaker cushion, comprising 25
to 35 parts by weight of carbon black having an iodine adsorption amount
of 70 to 120 mg/g and 0.5 to 2.0 parts by weight of a resorcin condensate
or a modified resorcin condensate based on 100 parts by weight of a
rubber component, and a tire having a breaker cushion using the same.
