To help make it easier to work the lugnuts onto the stud, the studs aren’t threaded for the first ¾ inch, which allows the lugnuts to slide down farther and not become cross-threaded while the tire is being put into place. For example, the lug nuts are already attached to the wheel with adhesive so they’ll stay in place before getting hit with the high-impact, nitrogen-powered wrench used to tighten and remove lugnuts. While incredible hand-eye coordination is involved, the tire is also prepped to make it faster for the changer. The jackman and the tire changer work together, using a 20-pound hydraulic jack to lift the car while the tire changer removes five lug nuts, switches out tires and then replaces the lug nuts. The front and rear tires each have a designated changer, and there’s also a front tire carrier and rear tire carrier to get the tires to the car.

The proper equipment plays a key role in making sure tire changers can do their job, and the team practices together to make sure each position is in top form. But it takes more than just speed to become a world-class tire changer it also takes precision.

That can cause precious seconds as the tire changer ends up hand-turning the nut to get it off. One of the biggest hazards for a tire changer is a hanging lugnut, which occurs when a lugnut has been loosened, but doesn’t come all the way off the stud.

Five off, five back on and then repeat on the other side. “You just have to get to a certain pace and then maintain that throughout the whole day.”įor the tire changer, every stop has 20 hits on a lug nut that have to be made perfectly.
NASCAR AVERAGE SPEED HOW TO
“You still get a rush out of it when you run top-five and top-10.”īut Brzozowski says a tire changer also has to learn how to go fast without going too fast and making a mistake. “It’s a lot of fun ,” says Scott Brzozowski, front tire changer. The very best tire changers make a complete tire swap in four seconds. Crews aim to make pit stops last no more than 11.5 seconds, during which time they have to change all four tires, refuel and get back on the road. How fast is a NASCAR pit stop?Ī tire change in a NASCAR race happens so fast that, to most of us, it’s almost impossible to tell what they’ve done.
NASCAR AVERAGE SPEED DRIVERS
Driver Ray Haroun won the purse of $14,250, with an average speed of 74.59 mph and a total time of 6 hours and 42 minutes.Anything drivers can do to shave off just a little more time can make a big difference at the NASCAR finish line, and that means every member of the pit crew has to be fast, agile and on top of their game at every pit stop. That May 30 marked the debut of the Indy 500–a grueling 500-mile race that was an immediate hit with audiences and drew press attention from all over the country. In 1911, low attendance led the track’s owners to make a crucial decision: Instead of shorter races, they resolved to focus on a single, longer event each year, for a much larger prize. Dubbed “The Brickyard,” the speedway reopened in December 1909. The surface was soon replaced with 3.2 million paving bricks, laid in a bed of sand and fixed with mortar. The track’s surface of crushed rock and tar proved a disaster, breaking up in a number of places and causing the deaths of two drivers, two mechanics and two spectators. In that first five-mile race on August 19, 1909, 12,000 spectators watched Austrian engineer Louis Schwitzer win with an average speed of 57.4 miles per hour. The rectangular two-and-a-half-mile track linked four turns, each exactly 440 yards from start to finish, by two long and two short straight sections.
