Johnson wrecks in test; speeds reach records
CONCORD, N.C. (AP) - A flat tire caused Jimmie Johnson to wreck Wednesday during an important test at Lowe's Motor Speedway, sending Goodyear officials searching to find the right rubber to use on the freshly paved surface.
Johnson had completed about 20 laps when he felt his right rear tire rapidly losing air. He couldn't complete the lap before the tire went flat, sending Johnson into the turn four wall.
"We're still looking at the tire and trying to find a concrete determination as to why the tire went down," said Rick Heinrich, product manager for Goodyear. "We don't know if it was a puncture or wear-related at this point."
Johnson, who has won four in a row and five of the last six races at Lowe's, left the track after his accident and was not available for comment. Track officials said he was not injured, and left because his Chevrolet was damaged beyond repair.
His accident was the only major incident during the two-day Goodyear test that will determine what tire should be used for the track's two big races in late May. Lowe's officials spent $3 million this winter to repave the surface, which was too slick last year after it underwent two grinding projects to smooth out the bumps.
Both of the track's premiere races were caution-plagued last year - there were 37 total in the two events - and the October race was a particular mess because of numerous tire failures.
It could take weeks for Goodyear to decide what tire will be best because the track surface will continue to change as more and more cars drive on it.
"At this point, it's our first look at the track," Heinrich said. "These guys were the first ones on it, the first laps. The conditions will be different than they will be two weeks from now."
Bobby Labonte, Kevin Harvick, Scott Riggs and Johnson were the only four drivers participating in this test. Goodyear could choose to hold another test, and the track will be open to all 43 teams in early May who wish to practice on the new surface. All that activity, plus weekly action from the various driving schools, should lay enough rubber on the track to change the conditions considerably before the May 20 All-Star race.
The only thing that's certain is that the speeds should reach record highs. Labonte said his laps Wednesday were just a tick off of Elliott Sadler's track record 193.216 mph.
But Sadler's mark was set in qualifying, when a car is designed to go as fast as possible for only one lap. The times posted during the test were in race trim, when a car is supposed to be much slower.
"It would not surprise me if you saw a 197-mph lap," track president Humpy Wheeler said.
Increased speeds is the danger on any repaved track. When Lowe's was last resurfaced in 1994, the qualifying record jumped from 177.352 to 181.439. So Goodyear and NASCAR will both work to find a proper way to control the speeds.
Although using horsepower-sapping restrictor plates is an option, no one really wants to use them.
"It's going to be fast, but fast enough that we need restrictor plates? Absolutely not," Riggs said. "That would be a horrible decision. We always set a new track record every time we go to a new surface. We expect the speeds to be faster. That's just how it is."
