Why Wheel alignment is necessary?

In wheel alignment, we check three most important suspension measurements of the car - Caster, Camber & Toe



In India, most people don't pay much attention to wheel alignment as they think its a very petty thing.But, let me tell you, its a small but an important thing for your car.It may take only 10-15 min to get your car aligned but it will save your tyre from wrong wear and tear.


This is what happens when your wheels are not aligned properly despite the tyre  having travelled only about 70 miles .You can see that one side of the tyre is brand new while on the other side, the wires are protruding.

Following symptoms can help you determine if your car needs alignment:
  • a) Uneven or rapid tyre wear.
  • b) Pulling or drifting away from a straight line.
  • c) Wandering on a straight level road.
  • d) Spokes of the steering wheel off to one side while driving on a straight and level road.

What is really wrong with your car if it (or steering) is vibrating?

At times you may experience your car is shaking. On certain highway speeds you may feel only your steering is wobbling while at slow speeds you may feel that the entire car is wobbling. It may make your drive really uncomfortable. In such a scenario, first of all you must check if your car is vibrating above speeds of 50-60 kmph or below it.

If your car is weirdly moving on slow speed that means that either one of your tyre or more than one tyres are swollen. Get it checked by a trained professional, because it means you need a tire change.You should be very particular about this because it can prove very risky to drive with a swollen tyre as there chances of their bursting.

If it is vibrating at speeds between 60 or 90 kmph, it means you need wheel balancing. Get your wheels balanced.

If the vibration persists above100-150 kmph, it means your tyres speed rating is not up to mark.

W indicates speed rating on your tyre.











Now, compare your tyres speed rating with the following chart, and in case your speed rating is lower than required, then either upgrade to better tyres like Pirelli Cintrato Series or Michelin, or avoid driving beyond speeds mentioned in the chart.

If still the problem continues you must get the suspension checked thoroughly,because at times due to play in some suspension parts, the vibration may persist.

What really is wrong with your car if it is "pulling" to one side?

Their are number of reasons if your car is pulling:
First and foremost you must check the wheel alignment.
But what if even after alignment, your car is still moving? Nobody knows and nobody's going to tell you.
But I will.
First of all check the air pressures of the tyres & then take a test drive.
At times the pulling is due to imbalance of air pressure in right and left tyres. E.g,  If in the left side, tyre pressure is 30 psi and on the other side the pressure is 15 psi, your car will obviously pull towards the side which has less pressure.
But still if the problem persists,
Check the front tyres of your car. Are they equally worn?.
At times the car moves to the side which has tyre that is more worn. If both your front tyres are not equal, make them even by changing the side or by checking the rear tyres. Rear tyres are mostly equal, so you can rotate both the tires to front.
Your problems will definitely be solved.
