Goodyear elects to replace right side tires at Fontana

Goodyear pulled 10 right side tires as a precautionary measure

after discovering unusual wear following qualifying on Friday.

Although the same tire code (4386) was used successfully at

Las Vegas and Charlotte Motor Speedway in the past, tire

specialists found thin thread in “small, localized

areas“ according to Stu Grant, general manager of global

racing tires.

“We decided to pull those tire (sequences) from the

system,” Grant added. “We’ll give them a tire

that doesn’t have the same shearogrophy image.”

Goodyear elected to review the data from previous right side

builds and sent the tires in question back to its headquarters in

Akron, Ohio, to examine the shearography image which uses

non-destructive lasers to measure and detect defects to the tire.

Goodyear will re-evaluate the tires following practice on

Saturday to determine whether any further action needs to be taken.
