Tire: Goodyear Eagle Speedway Radials
Number of Tires:
Nextel Cup: Left-side -- 1,500, Right-side -- 1,500;
Busch Series: Left-side -- 575, Right-side -- 575
Tire Codes: Left-side -- D-4024; Right-side -- D-4026
Tire Circumference: Left-side -- 87.3 in. Right-side -- 88.6 in.
Technical Inspection Inflation:
Left Front -- 26 psi; Left Rear -- 26 psi;
Right Front -- 40 psi; Right Rear -- 38 psi
Minimum Recommended Inflation:
Left Front -- 19 psi; Left Rear -- 17 psi;
Right Front -- 37 psi; Right Rear -- 34 psi
Estimated Pit Window: Every 55-60 laps, based on fuel mileage.
Notes: This is the first time Goodyear has brought this combination of left- and right-side tires to Darlington . . . both the NASCAR Nextel Cup and Busch Series teams will run the same tire set-up this weekend . . . this is the only track at which Nextel Cup teams will run this tire set-up in 2006 . . . Busch teams have run this tire once before -- at Nashville last month . . . as on all ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Darlington . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
Goodyear Quote -- Mark Keto, Lead Engineer, Stock Car Racing: "The only change with the tires compared to last year at Darlington is a different left-side construction. The right-side construction and the compounds are virtually unchanged. Obviously, the biggest factor with the tires at Darlington is high wear, brought on by the extremely rough track surface. We expect to see more than two seconds of give-up per lap over the course of a full fuel run."
I think they should stick to one tire composition for all tracks, the competition is already good without them trying to make it "better".
