two seconds. Meanwhile, the trio of Scheckter, Andretti and Lauda continued the battle they had been waging all weekend, with Scheckter leading by 1.7 seconds after three laps. On lap 4, Lauda was pressuring Andretti and tried to pass in the hairpin at the end of the curving back straight. He locked the Ferrari's brakes, but kept his foot down hard to avoid hitting Andretti's Lotus. The resulting flat spots on Lauda's tires caused a serious vibration throughout the race, and probably took away his chance of winning. Scheckter maintained a consistent cushion over the battle for second; after 25 laps, Andretti was 2.5 seconds behind and Lauda was 4 seconds back. Even as they periodically worked their way through traffic, the three leaders never lost contact for more than half a lap. The Long Beach circuit was not particularly suited for cars that generate much downforce, and the new Lotus, with its higher aerodynamic drag, could not match the straight line speed of Scheckter's Wolf; Andretti continually closed in through the corners, but could not find a way past. "I was preparing for a real banzai under braking," Andretti later said. "I needed to go from fifth to first gear in order to do it, and the way the gearboxes were in those days, I had maybe one or two tries to do that. My objective was to do it if I was in a position at the end of the race. Then I saw a twitch and, obviously, he had a tire that was slightly deflating." On lap 58, Scheckter's lap time suddenly increased by two seconds, and as he passed the pits, he pointed emphatically to the crew at his right front tire, which had developed a slow leak. The tire began locking up time and again under braking, but Scheckter decided he was going to stay out and go as far as he could. For 18 laps, he tenaciously fought a losing battle as he held off each of Andretti's desperate attempts to pass as his deflating tire got softer and softer. "It was not at the point that the tire was really going down, because it was the left side, not the right side, and it was not to the point that he really backed off any sooner because his braking point and turning point for the corner was the same." On lap 77, Andretti
