Tire notes from Atlanta

GOODYEAR TIRE NOTES

Tire: Goodyear Eagle Speedway Radials

Number of Tires: Left-side -- 1,700; Right-side -- 1,700

Tire Codes: Left-side -- D-4066; Right-side -- D-4080

Tire Circumference: Left-side -- 87.4 in.; Right-side -- 88.6 in.

Technical Inspection Inflation:
Left Front -- 30 psi; Left Rear -- 30 psi;
Right Front -- 50 psi; Right Rear -- 47 psi
Minimum Recommended Inflation
: Left Front -- 22 psi; Left Rear -- 20 psi;
Right Front -- 48 psi; Right Rear -- 45 psi

Estimated Pit Window: Every 48-52 laps, based on fuel mileage.

Notes: This is the first time Goodyear has brought this specific combination of left- and right-side tires to the track . . . while the left-side code will be the same for teams in all three NASCAR series at Atlanta, Nextel Cup teams will be running a different right-side code (D-4080) to account for their smaller fuel cell . . . this is the only track at which these codes will be used in 2007 . . . the important factors in designing a tire setup for Atlanta are the high speeds and loads, as well as the relatively rough track surface . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Atlanta . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
