Goodyear tire info for NASCAR at Daytona International Speedway

Goodyear has announced the tires that will be used by all three of NASCAR’s national series during Speedweeks at Daytona International Speedway.

While all three series will use the same type of tire compounds, only the Cup and Xfinity Series have raced on it before.

They first used the new compounds in July at Daytona. The previous tire compound used at Daytona had been introduced in 2013.

For the Trucks, compared to what was run at Daytona last February, there is a compound change to both the left and right-side tires to give the trucks more grip.

As on all NASCAR ovals greater than 1 mile in length, teams are required to run inner liners in all four tire positions at Daytona. Air pressure in those inner liners should be 12-25 psi greater than that of the outer tire.
