Zusammenfassung:	The present invention is directed to a tire having a tread comprising two shoulder portions and a center portion axially between the two shoulder portions, wherein at least one of the shoulder portions comprises a first rubber composition and the center portion comprises a second rubber composition different from said first rubber composition. The first rubber composition has a shear storage modulus which is at least 10% lower than the shear storage modulus of the second rubber composition, and 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.
