TIRE

A tire is disclosed comprising a tread (10) comprising two shoulder portions (6) and a center portion (8) located axially between the two shoulder portions (6). At least one of the shoulder portions (6) comprises a first rubber composition. The center portion (8) comprises a second rubber composition different from said first rubber composition. The first rubber composition has a shear storage modulus G'(1%) which is at least 10% lower than a shear storage modulus G'(1%) of the second rubber composition. The second rubber composition has a glass transition temperature which is at least 5% higher than the glass transition temperature of the first rubber composition.
