After seeing many cut tires during Indycar Series testing at Homestead-Miami Speedway, Brian Barnhart, president of Indy Racing League's competition division, said Friday he isn't concerned about it.
Twenty-one entries tested this week with no on-track incidents.
"We seem to cut tires each year at the open test, but it doesn't seem to be as bad during race weekends there," he said.
"I think some of them are done on pit road, as there are a few places where the concrete boxes and the asphalt pit lane are a little rough and exposed.
"Because of the long track times, we go yellow for each reported cut, but during the ensuing track inspection, we rarely find anything significant on the track surface.
"Sometimes during race weekends, because the sessions are so much shorter, we don't always go yellow for a cut unless the observers see an object."
Firestone, the tire supplier for the Indycar Series, has had a good reputation with their tires through the years, with very few wrecks caused by tire blowouts.
The Indycar Series season begins on April 5 on the streets of St. Petersburg, FL.
