Following a few days of rain, Auto Club Speedway of Southern California will be what's called a "green" race track when the NASCAR Sprint Cup Series race is run. Yates Racing drivers Travis Kvapil (No. 28 Teamyatesracing.com) and David Gilliland (No. 38 freecreditreport.com) both say a green race track here shouldn't pose any tire problems. Gilliland also says that the team's recent test at the track will be helpful.

TRAVIS KVAPIL -- No. 28 Teamyatesracing.com Ford Fusion --

"I actually feel that Fontana is going to be less of an issue than maybe an older place like Darlington or a concrete track like Martinsville or Bristol or Dover. The concrete tracks especially, they take time to rubber in and they're really hard on the tires when the track is green. It seems, from just a little bit of experience here, that this track doesn't have that trend to really wear out the tires. We kind of slide around anyway; we're not really stuck into this track. So, I really don't see it being a big issue here at this track this weekend. We got out there in the trucks the other day (Kvapil finished seventh in Saturday's truck race) and we never had any tire issues or anything with the trucks and it was a green, green track. So, I really don't anticipate any trouble."

HOW DOES THE CAR REACT TO A GREEN TRACK? "Probably a little less grip, more than anything. A track, just in general, has a tendency once it rubbers up just to get tighter. It's just a general characteristic that gives the rear tires, generally, more grip than the front. So, your rear tires kind of overpower your front tires -- as a general trend, not maybe for every track or every situation, but generally that's kind of the characteristic."

WILL THE TRACK BEING GREEN BE AN ISSUE HERE? "No, I don't think so. The good thing is, though, we all got to test here for two or three days and feet like we got a pretty good handle on our freecreditreport.com Ford Fusion, and I think that's going to end up what really pays off. If it goes into the night, like it might tonight, a lot of teams didn't stay for the night test when we were here, they just tested in the day. So, I feel pretty good. The track's going to be green, so you'll just have to watch the tires -- but, really, tires weren't close to being an issue, so I don't think a green race track will affect us. I think that if the tires were borderline and you had a green race track, then I think you'd have reason for concern."

GENERALLY, HOW LONG DOES IT TAKE FOR A GREEN RACE TRACK TO RUBBER UP? "I think with 43 cars on the track, once it gets going, after the first pit stop it will definitely be fine. I think even before that it will definitely start to rubber up."

HOW DOES THE CAR REACT TO A GREEN RACE TRACK? "Just less grip overall. So, if your car is tight it's going to get tighter, and if it's free it's going to get freer. The biggest thing is just less grip. And then as it gets a lot of rubber, toward the end of the race, you start to lose grip again. So, it goes through a swing."
