The present invention is directed to a rubber laminate (200, 300), comprising a first rubber layer (204, 304), a second rubber layer (206, 306), and an intermediate rubber layer (208, 308) disposed between the first and second rubber layers such that the first and second rubber layers do not meet; the first rubber layer (204, 304) comprising a sulfur donor and being substantially devoid of vulcanization accelerators; the second rubber layer (206, 306) comprising a vulcanization accelerator and being substantially devoid of sulfur donors; and the intermediate rubber layer (208, 308) being substantially devoid of sulfur donors or vulcanization accelerators. This laminate (200, 300) may be used as a tire retread cushion laminate. A method of retreading a tire using the laminate (100, 200) is also described. |
