Yes...I think that Cup and Busch at the time used a different compound.
But here is info from Jayski about this week's tires ... they are the same for all three series and the race today could prove to be another one of those fiascos since the Cup cars are harder on the right sides than the Nationwide cars are...
Tire:
Goodyear Eagle Speedway Radials (Sprint Cup & Nationwide);
Goodyear Wrangler Speedway Radials (Camping World Truck)
Number of Tires:
Sprint Cup: Left-side – 1,450, Right-side – 1,450;
Nationwide: Left-side – 575, Right-side – 575;
Camping World Truck: Left-side – 375, Right-side – 375
Tire Codes: Left-side -- D-4134; Right-side -- D-4186
Tire Circumference: Left-side -- 87.3 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 -- 23 psi; Left Rear -- 21 psi;
Right Front -- 49 psi; Right Rear -- 45 psi
Estimated Pit Window: Every 75-80 laps, based on fuel mileage (Sprint Cup).
Notes: Teams in all three NASCAR series will run the same tire codes at Dover this week, though the tires for the Sprint Cup and Nationwide Series will be branded "Goodyear Eagle," while the tires for the Camping World Truck Series will be branded "Goodyear Wrangler" . . . this is the same tire combination that Sprint Cup and Nationwide teams ran at Dover last fall . . . additionally, this is the same combination of left- and right-side tires that Cup and Truck teams will run at Michigan in two weeks . . . unlike on most NASCAR ovals one mile or less in length -- on which teams do not run inner liners -- teams are required to run inner liners in all four tire positions at Dover . . . air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
