Goodyear Quote: Mark Keto , Lead Engineer, Stock Car Tire Development:
"At Fontana, tires will really only be a factor in relation to pit strategy. Tire wear is not a major concern for teams at this track, so teams have always had the ability to choose between four-tire, two-tire and even no-tire stops at different points of the races at Fontana. As it has many times in the past, pit strategy and fuel mileage should be two major keys to success this weekend."
