Ever wondered how NASCAR changes tires so fast? It’s pretty mind-blowing; we’re just as impressed as you are!

NASCAR races are intense and competitive, and a single second of delay can be a life or death situation for a NASCAR racer. It’s crucial for racers to get the tires replaced quickly. 

Now, let’s find out the secret behind NASCAR’s super fast tire replacement process!

How Do NASCAR Pit Crews Change Tires So Fast?

NASCAR pit crews can change tires in about 15 seconds. Each pit crew consists of 5 members, which include:

  • 2 tire carriers
  • 2 tire changers
  • 1 refueller

OK, so here’s how 5 people change 4 tires in almost no time:

The First 7 Seconds

The pit crew waits for the arrival of the race car with all the equipment fully ready, including new tires, a refueling rig, and air guns. Once the car parks in the pit, the pit crew is allowed to enter the designated box area to start the tire replacement process. 

The refueller starts pumping 18 gallons of fuel into the car’s tank with a fuel hose. At the same time, the 2 tire changers and 2 tire carriers split up to work on each section of the car separately. 

One of the tire switchers slides a power jack under the vehicle to lift it off the ground. Then, they loosen the bolts as quickly as possible and roll the worn-out tires out of the box so that the carriers can safely enter the box and change the tires. After that, the tire carriers install the new tires.

Once the tires on the right side of the car are replaced, one of the tire carriers runs to the left side of the car with the jack.

Seconds 7 to 10

The tire carriers lift the car up for the tire changers to loosen the bolts of the left-side wheels. Then, the tire changers put away the old tires while the tire carriers mount the new tires.

The Last 5 Seconds
