What is Tire?

• It is a ring-shaped component that surrounds
  a wheel's rim to transfer a vehicle's load from
  the axle through the wheel to the ground and to
  provide traction on the surface traveled over.
• In short its a container of air around the rim
  which allows the vehicle to move easily over any
  surface.
• Tires vary according to the vehicle and its
  purpose of use.
• There are very large number of variety's of
  tires.
• There are tires that is used on different climate.

WHY IS TIRE ROTATION SO IMPORTANT at the time of
tire service?

• Tires rotate all the time as they roll down the
  road. But that's not what it means to "rotate"
  your tires. Rotating tires means moving them from
  one wheel to another and from left to right or
  back to front, or even diagonally.
• Tires tend to wear unevenly. The front tires tend
  to wear on the outside edges because the tire
  leans over when you turn a corner. The rear tires
  just follow the fronts, so they usually wear more
  evenly. If you leave tires in place, those
  outside edges on the front tires will wear down
  much faster than the rest. You'll have to replace
  the tires thousands of miles sooner.

• A poor alignment or unbalanced tires can also
  cause uneven wear.
• Rotating tires keeps them from wearing unevenly.
  That will make your ride smoother and handling
  safer. And it extends the life of your tires,
  saving you time and money in the long run.
• There are 3 key things that should happen during
  a tire rotation
• Each tire and wheel is removed from your car or
  truck, and moved to a different position.
• Air pressure should be checked and adjusted as
  necessary
• Brakes should be checked while the tires are off
  and it's easy to see and reach them

Proper Tire service

• Pressure
• Maintaining proper inflation pressure is
  crucial for getting the most out of your tires,
  both in long mileage and a comfortable ride. Stop
  by any Sullivan Tire and Auto Service for a
  complimentary air pressure check and
  adjustment. Come as often as you like, no
  appointment necessary! 
• Air pressure is measured in pounds per square
  inch (PSI). The PSI specifications for your
  vehicle can be found on the door frame of the
  driver side door (see image). Adjust the air
  pressure when the tires are "cold", which means
  check it early in the morning or after the
  vehicle has been sitting for at least 3 hours. 
• If you need to adjust for a "warm" tire, simply
  add 2-4 PSI to the vehicle manufacturer's
  recommended cold inflation pressure, and check
  the cold inflation pressure at your earliest
  convenience.  Even a perfectly healthy tire loses
  1-2 PSI per month, so it's important to check
  your pressures often Get your tire repaired at
  the first sign of a leak or nail hole puncture.
  Running your tires under inflated also means that
  you are overloading them, which can do
  permanent damage

• Alignment
• A bad jolt from hitting a curb or pothole can
  throw your front end out of alignment and damage
  your tires if not corrected promptly. Have your
  alignment checked at least 1-2 times per year, or
  at the first sign of the vehicle not tracking
  straight when driving on a straight stretch of
  road (a.k.a. "pulling")
• Rotation
• Regularly rotating your tires will help you
  achieve more uniform wear. Unless your vehicle's
  owners manual has a specific recommendation, the
  guideline for tire rotation is approximately
  every 5,000-7,000 miles, or roughly every other
  oil change.   
• Frequent tire rotations and tire inspections can
  help to identify an alignment or steering problem
  before too much damage occurs to the tire.

• Tread
• Checking your tread depth is one of the easiest
  ways to see if you need new tires. A tread depth
  gauge is an inexpensive and effective tool for
  measuring the amount of tread left on your tires.
  Hydroplaning can occur, even at low speeds, if
  the tread is not deep enough to channel the water
  from under your tires.
• Tread depth measurement is taken by a number out
  of 32nds of an inch, and should be taken from the
  tread grooves at three different areas of the
  tread (inner, center, and outside).
• Tread below 2/32" depth, the Department of
  Transportation (DOT) considers the tire as having
  reached the end of its useful life and should be
  replaced.
