What are The Tyre Specifications You Must Check Before Using a Tyre

The tyre specification is an important piece of information for any motorist to know, as it provides a lot of useful information about how the tyre has been made. There are a few important things to take note of when you check the tyre specification at Sunshine Tyres Shop. How many plies or layers there are in the tyre, which will help determine how durable it is and how long lasting its lifespan might be?

What Is Tyre Specification?

Any specification of any product is the easiest way to determine the quality of that specific product. For example, how many kilograms it will take before the tire becomes punctured and how much weight it can carry without being affected by pressure. It is a way of understanding how well the tyre can hold up with certain specifications.

Follow the Tyre Width:

The width of the tyre is how wide it stretches across from one side to another. This measurement can be found in millimetres, inches or as a percentage; we recommend you use mm for this article and all future articles about tyres. You’ll find that most modern cars will have a standard size of 225/45R17. This means that the width will be 225mm and the height 45%. It’s not possible to tell how much they are inflated by just looking at them so let’s move on swiftly!

Note The Aspect Ratio:

Note The Aspect Ratio

A 60 series tyre has an aspect ratio of 60, meaning the height (in millimeters) is how many times larger than its width. It is important to know this when considering tyre specifications because a 60 series tyre will have less grip in corners because of its increased weight while driving on turns and curves that require more lean over as opposed to cornering.

  • With an aspect ratio of 40, tyres are lighter, which can lead them being better for performance cars or tracks where they can put up with higher speeds
  • An aspect ration of 80 denotes heavy duty nature such as off-road use or tractor trailer tires
  • A 90 means heavier weights are used, but not as much as those with 100+ ratios

Measure rim diameter in inches:

Measure the diameter of your rim at its most narrow point. The measurement should be in inches, so if you have a metric tyre and want to convert it, use this conversion:

For example, for 225/65 R16 94H tyres (225mm wide x 65% aspect ratio) = 170.625mm, Convert that number from mm to inches and it’s 25.25″

Index The Speed Rating:

Index The Speed Rating

The speed rating is a safety indicator and does not affect how the tyre will ride. The maximum speed limit for an individual tyre’s use has to be clearly marked on its side, either in words or numerically.
