Drivers often weave from side to side on the track to get marbles off their tires. … These filler agents determine the tire’s softness and its grip. Tires lose traction throughout a race. During a tire stint, tires go through a change in composition.
Why do race cars weave back and forth?

Why do F1 drivers swerve side to side?
F1 tyres are very different to tyres used in endurance racing in terms of composition and size. F1 cars swerve to flex the body of the tyre. This generates heat which softens the compound providing more grip.
Why do F1 drivers heat up tires?
Why do formula cars warm their tires? … The reason why you’ll see the drivers swerving side to side on the warm up lap, is to warm up the tires so they’ll grip better at the start of the race.

Do all Nascar cars use the same engine?
All engines are the same size, and, in fact, they’re all the same except for certain parts on the engine. “The manufacturer supplies those parts to the teams and they assemble the engines.” One major area of differentiation among the engine design teams relates to valve timing.
