• How to Check Your Tyre Size?

2
Identify your tyres different sections

• There are two types of tyre size measurements
  metric and flotation. Metric is more commonly
  used and is more popular among consumers and
  well be talking about metric sizing today.
• Usually, the metric sizing is divided into 5
  sections, but it can span up to 7 different
  sections. These sections determine the
  composition, weight capacity, maximum speed
  capability, and more.
• Read the sidewalls of your current tyres. On most
  tyres, the size information is right on the
  tyres. An example of this information "P 185/75
  R14 82S."

Service Type

• The P stands for "passenger tyres"
• The first section designates the service type.
  This refers to what type of vehicle the tyre is
  manufactured for.
• The first two letters are considered your car
  tyres service type.
• P Passenger
• LT Light Truck
• ST Special Trailer
• T Temporary
• Some tyres dont have letters indicating their
  service type. Its safe to assume that these
  tyres are for passenger vehicles.

4
Section Width

• 185 indicates the width in millimetres
• This is the three-digit number that comes
  immediately after the service type. The section
  width measures the tyres overall width when it
  is mounted on a properly sized wheel.
• It measures the widest point of the inner
  sidewall to the widest part of the outer
  sidewall. Generally, wider tyres give more
  traction to the vehicle. However, this could also
  mean that it will be heavier, causing more fuel
  consumption.

5
Aspect Ratio

• 75 refers to the height of the tyre divided by
  the width (also known as the aspect ratio)
• The aspect ratio represents the height of the
  sidewall corresponding to the section width.
• The higher the number of the aspect ratio, the
  taller the sidewall. Tyres with a higher aspect
  ratio gives a more cushioned ride. It also means
  lesser road-noise. Tyres with a lower aspect
  ratio is way better it terms of mobility,
  handling, and cornering

6
Construction
Rim Diameter

• R indicates the radial construction
• A letter that identifies the tyre's internal
  construction follows the two digits used to
  identify the aspect ratio. There are three types
  of tyre constructions Belted Bias, Diagonal, and
  Radial.

• 14 refers to the diameter of the full tyre in
  inches.
• The Rim Diameter can be determined by checking
  the next digits after the letter. It is one of
  the most important numbers on your tyre.
• Often measured in inches, this is the wheels
  measurement from one end to the other.

7
Load Rating
Speed Rating

• 82 indicates the load rating
• Your tyres load index identifies your tyres
  maximum load-carrying capacity. These numbers are
  a representation of the actual pounds or
  kilogram.

• S indicates the speed rating
• The speed rating tells you the maximum speed your
  tyre is tested corresponding to your tyres load
  index. The tyres speed rating is also an
  indicator on the tyres performance capability,
  from traction, braking, and handling.
