Here’s how each of the four title contenders fared in those three previous races (Texas I was in April and Texas II was in November):
Kyle Busch
Texas I - 1st ... 34 laps led
Chicago - 8th ... 21 laps led
Texas II - 5th ... 2 laps led
Average finish for three races: 4.7
Carl Edwards
Texas I - 7th ... 124 laps led
Chicago - 15th ... no laps led
Texas II - 1st ... 36 laps led
Average finish: 7.7
Jimmie Johnson
Texas I - 4th ... no laps led
Chicago - 12th ... 118 laps led
Texas II - 11th ... no laps led
Average finish: 9.0
Joey Logano

Chicago - 2nd ... 1 lap led
Texas II - 2nd ... 178 laps led
Average finish: 2.3

Notes: Teams in all three NASCAR series will run the same combination of left- and right-side tires at Homestead this weekend . . . this is the first time these teams have run this tire set-up at Homestead, though they have run it at both Texas and Chicagoland this season . . . similar to what was run at Homestead last year, this right-side tire code (D-4686) employs Goodyear’s multi-zone tread technology, which combines two distinct tread compounds on the same tire -- the outboard 10 inches of the tread (Traction Zone) features a compound that is designed for grip, while the inboard two inches of the tread (Endurance Zone) is toughened to enhance durability on the part of the tire sees the most heat and takes the most abuse . . . different from Homestead 2015, this right-side tire features a construction change, and a compound change on the outboard 10 inches to give the cars and trucks more grip . . . compared to Homestead last year, this left-side tire code (D-4684) features an updated construction and mold shape, as well as a compound change for more grip . . . this tire set-up came out of a Goodyear test at Homestead December 14 . . . drivers participating in that test were Kevin Harvick, Chase Elliott, Brian Scott and Martin Truex Jr. . . . as on all NASCAR ovals greater than one mile in length, teams are required to run inner liners in all four tire positions at Homestead . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
