The ADVAN S.T. is Yokohama's Street/Sport Truck Summer tire developed to deliver a balance of high-speed capability, handling and comfort required by new-generation performance SUVs. The ADVAN S.T. is designed to add a new dimension to SUV performance that boosts driving pleasure, high-speed capability and traction on dry and wet roads. Like all summer tires, the ADVAN S.T. is not intended to be driven in near-freezing temperatures, through snow or on ice.On the outside, a silica blend tread compound developed specifically for the ADVAN S.T. provides grip that's less affected by extreme low or high temperatures. The tread compound is molded into a W-shaped directional tread pattern that uses a "5-pitch variation" tread block sequencing to provide agile handling at high speed and reduce noise. Designed specifically for the ADVAN S.T., the tire structure offers handling based on the needs of the lower center of gravity specific to new-generation performance SUVs and running stability in a high speed zone up to 186 mph (300 km/h) with two wide steel belts reinforced by spirally wound nylon cap plies providing strength and uniform ride quality, while the sidewalls are tuned to provide predictable handling.
