What the Red and Yellow Dots on New Tires Really Mean

What Causes a Tire To Get Out of Balance?

Tires become unbalanced when the weight around the tires and wheels is no longer evenly distributed. These are some possible causes:

  • Tire/wheel assembly becomes lighter as tires wear.
  • Tires are over or under-inflated.
  • Improper alignment results in abnormal tire wear.
  • A wheel weight has fallen off.
  • An improper wheel or tire repair.
  • Leaky valve stem replacement.
  • Cold mornings cause “flat-spots.”
  • The car has been sitting in one place too long.
  • The wheel is damaged from hitting a pothole or bouncing into a curb.

To extend tire life and even out wear, check tire pressure and rotate tire/wheels every 5,000 to 8,000 miles. However, if you notice vibration while driving, you’ll need to have the pros balance the tires.
