For several years now, Goodyear has been producing a very successful line of 30.0x9.0-15 radial drag tires. These tires utilize the same manufacturing and design technology that goes into Goodyear's high profile line of NASCAR Winston Cup tires. However, recent advances in tread compounding at Goodyear have driven the company's drag tire engineering staff to develop a new design that takes this product line to elevated levels of performance and longevity. This new design is called the D6303 Extended Life radial drag tire.
The D6303 gains a technological advantage over its predecessors with the new D4 tread compound. This compound actually has its roots in Goodyear's Pro Stock development program. A version of this compound, D4A, is currently being used on Goodyear's popular new D1239 Pro Stock tire. The remarkable quality of these two new compounds is that they offer more traction while providing improved wear characteristics. In fact, initial feedback from customers indicates that the D6303 tire is capable of getting over twice as many passes as the tire it replaces. This initial feedback has also made it apparent that this tire is ideal for high horsepower stock cars with automatic transmissions. Paul Preston, the drag tire engineer who formulated the D4 compound, explained the major effort that went into developing this new product by saying, "Drag racers are very savvy tire users. They are very knowledgeable. Our objective is to give them the best compound for their money."
The most exciting milestone in the short life of this tire came on February 18, 2001 at the NHRA Checker, Schuck's, Kragen National Event in Phoenix, Arizona. After an impressive weekend, Al Corda drove this tire to a final round victory in Stock Eliminator. This was the first national event win for the new D6303, and the 13th for Corda who has now won NHRA national events in 4 consecutive decades. It was very satisfying for Goodyear to have its new product win a national event so soon after its introduction. It was even more satisfying to have this same product be the tire of choice for a sportsman driver who is as well-known and highly respected as Al Corda.
The relationship between Goodyear and Corda has lasted almost a decade. It started when the company conducted a few tire tests at Corda's Rock Falls Raceway in Eau Claire, Wisconsin. The relationship quickly developed to the point where Corda has become one of Goodyear's closest customers. Corda's mechanical engineering background has also made him a valuable source of information and feedback for Goodyear's drag tire engineering staff.
Corda's Yellow C/SA Firebird is one of the most recognizable cars at the track. This Pontiac and Next Generation sponsored machine is powered by GM's 350 cubic inch LS1 V8 engine. This engine, along with the short wheelbase of the chassis, makes this car one of the most competitive at the dragstrip. Over the past few years, Corda has been running Goodyear's traditional line of radial drag tires on this car. However, he switched to the D6303 drag tire earlier this year. The improvement to the car's performance was immediate. On Corda's Firebird, which is normally very hard on tires, the D6303's robust D4 compound has allowed him to double the number of passes that he can make on a set of tires. Also, Corda's onboard data acquisition system clearly showed the D6303 had excellent launch characteristics. When asked to comment, Corda responded, "I have put sixty passes on this new tire so far. It has yet to spin...not even once! I think that is amazing!"
Goodyear would like to congratulate Al Corda on his victory in Phoenix and thank him for helping us showcase our new tire in the Winner's Circle. The victory has made all of the hard work that went into developing this awesome new tire worth while. Goodyear wishes Al all the best and is confident that he will bring the Goodyear Eagle name many more victories in the future.
