Goodyear Tire Facts and Notes: Michigan Speedway and Mid-Ohio

NASCAR Sprint Cup Series – Race No. 23 – Pure Michigan 400 
Michigan International Speedway (2.0-mile oval) – Brooklyn, Mich. 
Fast Facts for August 16-18, 2013 

Tire: Goodyear Eagle Speedway Radials

Set limits: Sprint Cup: 5 sets for practice/qualifying and 10 sets for the race

Number of Tires: Sprint Cup: Left-side – 1,200, Right-side – 1,250

Tire Codes: Left-side -- D-4558; Right-side -- D-4560

Tire Circumference: Left-side -- 87.5 in. (2,222 mm); Right-side -- 88.4 in. (2,246 mm)

Technical Inspection Inflation: Left Front -- 30 psi; Left Rear -- 30 psi;
Right Front -- 55 psi; Right Rear -- 50 psi

Minimum Recommended Inflation: Left Front -- 24 psi; Left Rear -- 22 psi;
Right Front -- 51 psi; Right Rear -- 48 psi

Notes: Teams in both NASCAR series in action at Michigan this weekend will run the same right side tire code (D-4560), though they will run different left side codes.  The Sprint Cup Series’ left side code is D-4558. This is the same combination of left and right side tires that Sprint Cup teams ran at Michigan earlier this season and in August last season. This is also the same tire set-up that Cup teams have run at the last two races at Kansas and April 2013 and October 2012. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tire positions at Michigan. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

Michigan International Speedway (2.0-mile oval) – Brooklyn, Mich. 
Fast Facts for August 16-17, 2013 

Tire: Goodyear Wrangler Speedway Radials

Set limits: Camping World Truck: 5 sets for the event

Number of Tires: Camping World Truck: Left-side – 400, Right-side – 400

Tire Codes: Left-side -- D-4554; Right-side -- D-4560

Tire Circumference: Left-side -- 87.5 in. (2,222 mm); Right-side -- 88.4 in. (2,246 mm)

Notes: Teams in both NASCAR series in action at Michigan this weekend will run the same right side tire code (D-4560), though they will run different left-side codes. The Camping World Truck Series’ left side code is D-4554, and is the same left side that truck teams ran at Michigan last August. This is the first time they have run this right side tire at Michigan. Compared to what they ran at this track last year, this right side features just a slight reduction in gage (tread thickness). Truck Series teams did run this exact combination of left and right side tires at Kansas earlier this season. As on all NASCAR ovals greater than one mile in length, teams are required to run inner liners on all four tire positions at Michigan. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

NASCAR Nationwide Series – Race No. 22 – Nationwide Children’s Hospital 200

As on all NASCAR road courses, teams will not run inner liners in their tires at Mid-Ohio.

Wet Weather Tires: Goodyear will also bring 700 wet weather radials (D-4215) to Mid-Ohio for use by Nationwide Series teams, should NASCAR decide that conditions warrant.
