What is the difference between red and black tires in indycar

Usually, on a road course filled with long, flowing corners, IndyCar's Firestone red tires produce significantly faster lap times. That's what everyone inside the paddock expected to be the case Friday, and that's why so many of the drivers exited their cars with quizzical looks on their faces. No one, with the exception of James Hinchcliffe, turned their fastest lap of the day on red tires. And even that was an anomaly, admitted Hinchcliffe, who finished the day atop the speed chart I don't think that we were as high up before switching to reds as we would have liked or where we were capable of being, and then we threw on the reds, and the balance just fell apart.

The car was — I've never been this high up on the speed chart and so unhappy with the balance of my race car. Hinchcliffe can at least take solace in knowing most of the rest of the paddock feels the same way. The driver who finished P2, Circuit of the Americas winner Colton Herta, was just as flummoxed by what he saw out on the track as Hinchcliffe.

So while it's the preferred tire to have, you also have to learn how to take care of them. If you abuse them, they lose traction, and then you're just sliding around. The problem is that the reds are limited.

We don't get as many of them as we do the black tires, so we have to be economical with them. That means we don't get to practice with them as much as we'd like. The first time I experienced the red tires was during the season opening race at St. I hadn't used them in testing, practice or qualifying -- just during the race.

The first stint on reds was pretty good, but in the second stint I had trouble at about the 18th lap.
