New Tire Set-up Adds Stability at Daytona:
Daytona International Speedway was one of the NASCAR tracks on a busy Goodyear spring
testing schedule this year.

After running the same successful tire combination at Daytona since July 2013, Goodyear
returned to the “World Center of Speed” in April with a focus of exploring options for
increased grip.  For this week’s races, Goodyear’s new tire combination features new
tread compounds on both sides of the car. 

These new compounds will add grip, not necessarily with a goal to increase speeds, but to enhance the stability of the cars. With restrictor plate-style racing, being within inches of other cars virtually all the way around the track is a reality, and enhanced stability is a welcome feature to combat the buffeting
of the air caused by the close-quarters racing.

Teams in both the Monster Energy NASCAR Cup and Xfinity Series will run the same
Goodyear tire set-up at Daytona this week, the first time these teams have run
either of these two tire codes. This tire set-up came out of a Goodyear test at Daytona
on April 12. Drivers participating in that test were Danica Patrick, Joey Logano, Ryan
Newman, Erik Jones and Alex Bowman.

Compared to what was run at Daytona in February, there is a compound change to both the left- and right-side tires to give the cars more grip. 

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