What Causes Wheel Spin During Acceleration?
2 Answers
The reason for wheel spin during acceleration is insufficient tire contact area and inadequate friction, causing slippage when too much power is applied. Methods to prevent wheel spin are as follows: Avoid stopping on slippery surfaces whenever possible: If wheel spin occurs during acceleration, remove mud or snow. On smooth surfaces, spread dry ash, dry sand, or use any anti-slip materials, and start in second gear with light throttle. Use snow chains: On icy or snowy roads, install snow chains (usually only on the rear wheels). For four-wheel-drive vehicles, engage the front drive. Do not use snow chains on muddy roads. Select the correct gear: Choose the appropriate gear based on the road surface friction coefficient and conditions. Start in second gear (first gear is prone to wheel spin), apply light throttle and slowly release the clutch. You can drive at high gear with low speed, but avoid using low gear at high speed, as this can easily cause wheel spin.
Regarding the issue of wheel spin at start-up, I believe it's mainly related to the tires. If the tire pressure is too low, the tires become wrinkled, reducing the contact area with the road surface and resulting in insufficient friction, causing slippage when accelerating. Worn-out treads are also critical, especially on rainy days or when there are water stains or oil on the road, as the grip almost disappears. With decades of driving experience, I remind everyone to develop the habit of checking tire pressure monthly, keeping it at the manufacturer's recommended value, and regularly observing tread wear. If the wear is severe, replace the tires early. Also, avoid stomping on the accelerator at start-up; gently pressing and releasing to maintain steady RPM can solve most problems. Considering switching to rain tires during seasonal changes is also a good strategy for added safety.
