PROBLEM TO BE SOLVED: To obtain a tire having a constituent element composed of a rubber composition containing a pre-hydrophobated precipitated silica aggregate of a raw silica particle by treating a colloidal silica with both an organomercaptosilane and an alkylsilane. SOLUTION: This tire comprises at least one constituent element composed of a rubber composition containing a pre-hydrophobated precipitated silica aggregate. The tire constituent element is, for example, not limited, and is a tire tread, a side wall and/or a side wall insert. The pre-hydrophobated precipitated silica aggregate is, for example, intentionally prepared by treating a precipitated silica with a combination of an organomercaptosilane and an alkylsilane.
