All three NASCAR national series are in action this weekend with visits to Pocono Raceway and Iowa Speedway.

The Camping World Truck and Sprint Cup Series are in Pocono and will use the same right-side tire setup. That is the only similarity between the two series as there will be a different left-side tire setup for both.

The Xfinity Series will make its second trip to Iowa Speedway on Saturday night and will use a tire setup that has been specific to the track since last season.

SPRINT CUP TIRE INFO:

Set limits: five sets for practice and qualifying and eight sets for the race

Tire Codes: Left-side — D-4708; Right-side — D-4710

Tire Circumference: Left-side — 87.44 in. (2,221 mm); Right-side — 88.23 in. (2,241 mm)

Minimum Recommended Inflation: Left Front — 19 psi; Left Rear — 19 psi; Right Front — 37 psi; Right Rear — 34 psi

While Sprint Cup and Camping World Truck Series teams will run the same right-side tire code at Pocono this weekend, they will run different left-side codes. For Sprint Cup teams, this is the same combination of left and right-side tires they ran at Pocono in June.

While Pocono is the only track Sprint Cup teams will run this left-side tire code (D-4708), they did run this right-side code (D-4710) at Indianapolis last weekend. As on all NASCAR ovals greater than one-mile in length, teams are required to run inner liners on all four tire positions at Pocono. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

TRUCK SERIES TIRE INFO:

Set limits: four sets for the event

Tire Codes: Left-side — D-4650; Right-side — D-4710

Tire Circumference: Left-side — 87.56 in. (2,224 mm); Right-side — 88.23 in. (2,241 mm)

Minimum Recommended Inflation: Left Front — 18 psi; Left Rear — 18 psi; Right Front — 37 psi; Right Rear — 34 psi

This is the first time Camping World Truck teams have run either of these two tire codes. Compared to what was run at Pocono last August, this left-side tire (D-4650) features a compound change to give the trucks more grip and a construction change to bring it into line with what is run at other speedways.

This right-side tire (D-4710) features an increase in tread gauge (thickness) compared to what was run in August 2015. As on all NASCAR ovals greater than one-mile in length, teams are required to run inner liners on all four tire positions at Pocono. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.

XFINITY TIRE INFO:

Set limits: seven sets for the event

Tire Codes: Left-side — D-4546; Right-side — D-4648

Tire Circumference: Left-side — 87.60 in. (2,225 mm); Right-side — 88.39 in. (2,245 mm)

Minimum Recommended Inflation: Left Front — 18 psi; Left Rear — 18 psi; Right Front — 36 psi; Right Rear — 34 psi

This is the same combination of left and right-side tires Xfinity Series teams have run at Iowa since last season. This left-side tire code (D-4546) has been run by Xfinity teams at Iowa since 2012, while this right-side tire code (D-4648) was introduced at the track in 2015. As on most NASCAR ovals one-mile or less in length, teams will not run inner liners in their tires at Iowa.
