Abstract

The object is to improve both of low rolling resistance and strength of a tire. Disclosed is a tire comprising a side-wall, a case and an inner liner, wherein the side-wall comprises a rubber composition (A) for a side-wall which comprises 100 parts by weight of a specific rubber component (A1) and 20 to 45 parts by weight of a filler (A2), the case has a code coated with a rubber composition (B) for a case code which comprises 100 parts by weight of a specific rubber component (B1) and 20-45 parts by weight of a filler (B2), and the inner liner comprises a rubber composition (C) for an inner liner which comprises 100 parts by weight of a rubber component (C1) containing a butyl rubber at a content of 35-80 wt% and 15-45 parts by weight of a carbon black (C2) having a nitrogen-absorption specific surface area of 20-45 m2/g.
