A racing tire sized for a racing truck includes a tread including first and second layers formed of first and second rubber compositions. The first layer defines a first portion of a road-contacting surface of the tread. The second layer defines a second portion the road-contacting surface of the tread and is only partially covered by the first layer. The first rubber composition includes 70 to 92 phr of a solution-polymerized styrene butadiene rubber and at least one of an isoprene rubber and a polybutadiene rubber, and 50 to 160 phr of silica. The first rubber composition includes a resin at a higher phr than the second rubber composition. The second rubber composition includes 70 to 100 phr of a polyisoprene rubber, 5 to 30 phr of silica, and carbon black. Carbon black is at a higher phr in the second rubber composition than in the first rubber composition.
