NEOTOTO RTP SLOT The tires on a Champ Car are completely smooth to maximize the amount of rubber touching the track surface. The rubber on the face of the tires is extremely soft. To handle the incredible forces applied to them, the tires of a Champ Car are much different from the tires you find on your car. The tires on a passenger car are meant to last 40,000 to 60,000 miles, while the tires on a Champ Car are designed to last 60 to 70 miles! Between the size of the contact patch of a Champ Car tire and the softness of the rubber, the tires have incredible adhesion. Especially in the street course events, the driver continually tests the boundaries of tire adhesion -- the limit to how fast the driver can accelerate, brake or take a corner is determined ultimately by the tires. With less than 1 inch of up/down travel available, the ride can get extremely stiff.|Kapal Selam Induk Jepang
