Choosing the right tyre size is crucial for optimising your vehicle’s performance and safety on the road. Tyre sizes are represented by a series of numbers and letters, each conveying specific information about the tyre’s dimensions, construction, and capabilities.
Rim Diameter (e.g., 15):
Indicates the diameter of the wheel rim in inches. This measurement is crucial when buying new wheels for existing tyres.
Width (e.g., 195):
Indicates the section width of the tyre in millimetres. This measurement represents the distance between the sidewalls of the tyre.
Tyre Construction (e.g., R):
The “R” signifies radial ply construction, a common method for constructing passenger tyres. Radial tyres are widely used for their durability and performance.
Aspect Ratio (e.g., 65):
Represents the tyre’s aspect ratio, indicating its height from the base of the tread to the rim. Expressed as a percentage of the tread width, a lower profile tyre will have a smaller aspect ratio.
Load & Speed Rating (e.g., 91 V):
A symbol indicating the maximum load capacity and speed at which the tyre can safely operate. It’s vital to adhere to these ratings for optimal performance and safety.
Overall Diameter (OD):
The overall diameter of the unloaded tyre in millimetres.
Type Definition:
Various abbreviations like LWT (Line White Tubeless), OWT (Outline White Letters Tubeless), RBT (Raised Black Letters Tubeless), RFT (Run Flat Technology), RWT (Raised White Letters Tubeless), TL (Tubeless), and TT (Tubetype) denote specific tyre types and features.
Understanding these metrics ensures you make informed decisions when selecting tyres, promoting a smoother and safer driving experience. If you ever have questions or need assistance in deciphering these codes, our knowledgeable team is here to help guide you on the road to optimal tyre selection
Alignment means that all four tyres are consistent with each other and are positioned to optimise contact with the road. It consists of three elements – caster, camber and toe.
The pressure of the air inside a tyre. Tyre pressure is measured in psi (see psi).
Aspect ratio is section height divided by section width and multiplied by 100. The higher the figure, the higher the tyre’s section height, the smoother the ride. The lower the figure, the greater a tyre’s section width and the safer the tyre – best for high speed cars.
Balancing a wheel (or tyre) ensures that the weight is evenly distributed. This prevents vibration and uneven tyre wear.
Camber is the angle that the tyre tilts – 0 degrees means the tyre is perfectly perpendicular to the road. If it tilts in at the top towards the vehicle, the camber is negative. Positive camber is when the tyre tilts away from the vehicle at the top.
The casing of a tyre is the outside part of a pneumatic tyre (i.e. not the inner tube).
The pressure of a tyre before the vehicle is driven and the tyre is warmed up.
An innerliner is a lining inside a tyre that prevents air leaking.
The maximum weight a tyre can safely carry.
Tyre markings are the symbols on a tyre’s sidewall to indicate (for example) load index.
PSI is ‘pounds per square inch’ and is a standard measurement of pressure. Basically, it’s the amount of force exerted over one square inch. Normal tyre pressure is 32 psi.
Rim and wheel are often used interchangeably – it is the part that the tyre sits on.
The force required to maintain forward momentum in a straight line at a constant speed.
Run Flat Technology tyres are designed to withstand punctures, thereby allowing the driver to continue to drive even when the tyre is completely deflated. The safety benefits are that it avoids the need for drivers to stop by the side of the road to change tyres and giving drivers ample time to make it home or to the nearest tyre replacement centre, provided they drive within the accepted speed limit and safe distance.
The part of a tyre between the edge of the wheel and tread.
Small slots in a tyre’s tread.
The maximum speed a tyre can travel, corresponding to its load index.
The rubber part that sits on the wheel.
Tyre size is actually a set of numbers and letters that define a tyre’s specifications, such as section width (from sidewall to sidewall), aspect ratio, speed rating and diameter of the wheel the tyre is made to fit on.
The raised part of the rubber on a tyre.
Features built into a tyre to let the driver know that the tyre is worn sufficiently to necessitate changing.
When a tyre is not inflated enough – it can result in a shorter lifespan and reduce fuel economy. Steering and cornering will be negatively affected and rolling resistance will be increased.
