Wheel alignments. Why are they so important?

Wheel  alignments. Why are they so important? Why should you spend more money on this service when you buy a set of tires?

The simple answer is, because you don't want this to happen to your N10,000+ set of tires within a few months:

See the right side of the picture? That shiny stuff? That's the steel belts that are part of the inside of the tire. You are not supposed to see that. Ever. See how deep the tread is on the left side of the picture? If this vehicle were aligned properly, the tread on the right side of the picture would be the same as the left. 

So ensure you go for a wheel alignment often to prolong your tire life.
