Notes: While teams in all three NASCAR series in action at Chicagoland  this week will run the same left-side tire code, Sprint Cup teams will  run their own right-side tire code . . . Sprint Cup teams have run this  left-side code (D-4392) at Chicagoland since 2011 . . . they have also  run this left-side at Texas and Darlington earlier this season . . .  this is the first time they have run this right-side code (D-4618) at  Chicagoland, though they did run it earlier this season at Texas . . .  this right-side tire employs Goodyear's multi-zone tread technology,  which combines two distinct tread compounds on the same tire -- one on  the inboard two inches of the tread for endurance and heat resistance,  and one on the outboard 10 inches of the tread for traction . . . this  tire combination was confirmed at a Goodyear test at Chicagoland on  June 10 . . . teams and drivers participating in that test were No. 11  Joe Gibbs Racing Toyota with Denny Hamlin, No. 22 Penske Racing Ford  with Joey Logano, No. 27 Richard Childress Racing Chevrolet with Paul  Menard and No. 48 Hendrick Motorsports Chevrolet with Jimmie Johnson .  . . as on all NASCAR ovals greater than one mile in length, teams are  required to run inner liners in all four tire positions at Chicagoland  . . . air pressure in those inner liners should be 12-25 psi greater  than that of the outer tire.
