Tire: Goodyear Eagle Speedway Radials
Number of Tires: Nextel Cup: Left-side -- 1,500; Right-side -- 1,500
Tire Codes: Left-side -- D-4060; Right-side -- D-4062
Tire Circumference: Left-side -- 87.4 in. Right-side -- 88.7 in.
Technical Inspection Inflation:
Left Front -- 30 psi; Left Rear -- 30 psi;
Right Front -- 48 psi; Right Rear -- 45 psi
Minimum Recommended Inflation:
Left Front -- 22 psi; Left Rear -- 20 psi;
Right Front -- 45 psi; Right Rear -- 42 psi
Estimated Pit Window: Every 48-52 laps, based on fuel mileage
Notes: This is the second time this season that Goodyear has brought this combination of left- and right-side tires to the track, with teams having run these codes recently at Dover . . . Craftsman Truck teams will be running a different set of codes this weekend at Michigan . . . as on all ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Michigan . . . 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: "This is the same set-up Cup teams ran a couple weeks ago at Dover, so they've all had a good chance to see how they react to chassis changes. These codes have a new construction compared to last year at Michigan, with a tougher compound on both sides for improved treadwear".
Hopefully they will wear better than they have as of recent.
