Understanding about the Right Tyres Prees Heath will enable you to make the right choice when it comes to purchasing new tyres. Fortunately, learning to read tyre size and determining one for your car is not a tough task. It is important to remember that real physical measurements like diameter and width are important considerations in determining the right size. But there are also other details that are worth taking note of to pick the right tyres for your car.

Where Can You Find the Size of Your Tyre?

Irrespective of your car model, you can find the tyre size that is recommended by your manufacturer by going through the owner’s manual. But if you are not able to find your owner’s manual or it is misplaced, you can look at other places like the door jamb on the driver’s side.

Reading Tyre Size

After you go through the example mentioned below, reading the size of your Tyres Tilstock will seem fairly easy to you. Let’s begin by taking the example of a tyre in whose sidewall the following information is engraved:

P225/70R16 91S

  • In most cars, you can see the sequence of letters and numbers starting with P. P denotes the short form for P-metric. It is the designation given by the Tyre and Rim Association for a type of tyre that is used for the passenger car. It symbolises that this particular tyre was manufactured to be employed in passenger vehicles. Passenger vehicles refer to vehicles like cars, SUVs, minivans, and other pickup trucks.

If instead of P the letters LT were mentioned then it would have denoted LT-metric. This designation by the Tyre and Rim Association is given for a tyre type that is used for a light truck.

  • Apart from the alphabet, the first number that the sequence contains is 225. This number denotes the width of your tyre in a millimetres unit. The width of your tyre denotes the measurement from sidewall to sidewall. In the example mentioned above, P225 is for a passenger car that has a width of 225 millimetres.
  • After P225 there is a slash after which the next number begins. It denotes the aspect ratio of your tyre. Aspect ratio indicates how tall the profile of your tyre is. Aspect ratio is always mentioned in percentage. Tyre manufacturers arrive at aspect ratio by dividing the height of your car tyre by the rim of its width.
  • After 70, you can see a letter. This letter points to the kind of internal construction that your tyre has. The internal construction of your tyre maintains its stability. Usually, there are two kinds of construction, namely, radial (denoted by R) and bias-ply (denoted by D). Most tyres that you can see on various cars are manufactured through radial construction. That is why we can most commonly observe R in the tyre reading of most sidewalls.
  • The subsequent figures indicate the load index of your tyre. It indicates the amount of weight in the unit pound that your tyre can support when it is adequately inflated. But this number is not the exact weight that the tyre can carry.
  • Lastly, S in the sequence given above demonstrates the speed rating of your tyre. It corresponds to a specific speed capability that is derived on the basis of a standardised laboratory test. A tyre that has a speed rating denoted by S is rated for up to 112mph.

Now that you know how to read your car tyres like a pro, you are sure to benefit from a sound decision while purchasing a new pair of tyres for your car.
