INDIANAPOLIS -- Sprint Cup teams will receive extra tires and NASCAR is expected to have at least one competition caution early in today's Allstate 400 at the Brickyard at Indianapolis Motor Speedway as tire wear is a concern.

Tires have shown excessive wear after few laps causing concern for today's 160-lap race.

"The problem is that you have a 3,500-pound race car with a lot of horsepower that doesn't handle real well going around a 2.5 mile track that has flat corners with an abrasive surface," says Chris Carrier, crew chief for Sam Hornish Jr.

"Asking anybody to build a tire and come to this place and run two days of practice for a 400 mile race with the weight of these racecars, horsepower and amount of load is like asking somebody to invade Russia with a loaded shotgun."

Robin Pemberton, NASCAR's vice president of competition, says teams will have up to 10 sets along with any sets they didn't use Saturday.

"The track is very abrasive because we don't' run on it very often," Pemberton said. "Goodyear's doing the best they can."

Without a companion event at the track, the surface does not get as much rubber buildup, causing the problems.

Fast time

Jimmie Johnson won his second pole of the season and credit can go to his high school swim coach.

Johnson said he spent time visualizing a lap around the track before qualifying, a practice he's done for years.

"My swim coach in high school had us memorize our starts, how many strokes it took to get to the end of the pool, your kick turn and back to the finish," Johnson said.

"That just got in my mind at a young age and has been real helpful for me in the Cup series."

Johnson scored his 15th career pole with a lap of 181.763 mph. Mark Martin starts second after a lap of 181.393 mph. Ryan Newman (180.970 mph), Kasey Kahne (180.810) and Jeff Gordon (180.545) complete the top five.

Staying put

Jamie McMurray said he'll remain with Roush Fenway Racing despite reports that he'll drive elsewhere next year.

"The truth is I'll be there with [sponsor] Crown Royal," McMurray said Saturday. "There's not a question. It's 100 percent. I will be here ... at Roush Fenway."

n ESPN.com, citing unidentified sources, reported that Martin Truex Jr. has agreed in principle to a two-year deal to remain at Dale Earnhardt Inc.

New engine

Ford officials have discussed a new engine with NASCAR officials, according to Doug Hervey, North American Operations Manager, Ford Racing Technology.

"We've presented our plans to them for a new engine," Hervey said. "We've got prototype engines that we're evaluating right now."

Busch wins Kroger 200

Kyle Busch led all but three laps Saturday night to win the Kroger 200, his sixth NASCAR Nationwide Series victory of the season. Busch's win Toyota's 15th in 22 Nationwide races, but the first event since NASCAR's mandate Wednesday to cut down the horsepower in Series engines knocked 15 horsepower out of Toyota's engines. NASCAR changed the parameters after rival teams complained, even though Toyota was within the rules.

Pit stops

Jeff Gordon was the fastest in the final practice session Saturday with a lap of 174.496 mph. He was followed by Greg Biffle (174.243 mph), Ryan Newman (174.236), Jimmie Johnson (173.910) and Denny Hamlin (173.728). ... Marcos Ambrose qualified for his second Cup race but the first for the team co-owned by former UNC basketball player Brad Daugherty.
