Learn essential tyre maintenance practices to improve safety, increase fuel efficiency, and prolong tyre life. Explore Dunlop's expert recommendations for inspection, inflation, alignment, and more.
Considering how important tyres are for a smooth and safe drive, it is surprising just how quick and easy it is to care for your tyres. By following our tyre care tips, and conducting simple regular checks, you will not just save time and money, but more importantly, stay safe on the road.
Passenger Car Tyre - A 'P' or no letter at all indicates a passenger car Tyre.
Width (Millimeters) - This is the section width of your Tyre, in millimeters, measured from sidewall to sidewall.
Aspect Ratio (height/width) - This is the ratio of the height of the tyre sidewall, expressed as a percentage of width. An aspect ratio of 60, for example, indicates that the tyre's sidewall height is 60% of its width.
Radial (construction) - This tells you that the tyre is a radial construction. Almost every new tyre built today is a radial tyre.
Diameter (inches) - This is the diameter in inches of the rim of the wheel that the tyre has been designed to fit on.
Load Rating - This is the load index of a tyre, also called load rating, and corresponds to the maximum weight the tyre is designed to carry. It can be found on the tyre sidewall, next to the diameter. For safety reasons, you should never overload your tyres or choose replacement tyres with a load index lower than your vehicle manufacturer recommends.
Speed Rating - The speed rating is the maximum legal speed for a tyre when it is correctly inflated and in use under load. You will find your tyres speed rating printed on the sidewall, and represented by a letter. A tyre with a speed rating of V, for example, has a maximum speed of 240 km/h. When buying replacement tyres, it is essential to match their speed rating with the speed capabilities of your vehicle.
The Load Index is a numerical code associated with the maximum load a tyre can carry at the speed indicated by its Speed Symbol under service conditions specified by the tyre manufacturer.
The Speed Symbol indicates the maximum speed at which the tyre can carry a load corresponding to its Load Index under service conditions specified by the tyre manufacturer.
Correlation Between Speed Symbol(SS) and Maximum Speed
The "DOT" symbol certifies the tyre manufacturer’s compliance with the U.S. tyres made in the United States have the DOT serial number located on the inside sidewall near the rim.
Manufacturers Name & Brand
Commercial Name (Pattern)
tyre Size Designation.
The word ‘radial’ to identify radial ply tyres. R in size marking also indicates radial ply tyres
The word ‘tubeless’ to identify tubeless tyres (or ‘tube type’ (optional) where appropriate)
The ‘E’ certifies that the tyre complies with the dimensional, performance and marking requirements of ECE Regulation 30.
Service description – ‘Load Capacity Index’ and the ‘Speed Category Symbol’, for example ’79V‘
TWI – is the abbreviation of ‘Tread Wear Indicator’ and may be found in the shoulder or upper sidewall part of some tyres.
Directional pattern tyres.

A tyre without proper inflation does not work as a tyre at all.
A tyre only functions when it is supported by the air inside.
All its characteristics are related to inflation pressure.
Therefore it is very important to maintain tyre inflation properly.
All new Dunlop tyres have a smooth surface after production, which will gradually wear away through moderate breaking-in of tyres. Sudden acceleration and braking, and hard cornering should be avoided until the breaking-in process has been completed. This process also helps build the tyre up to its maximum grip level.
Premature tyre wear can be caused by a number of factors such as improper inflation, improper wheel alignment, rough driving conditions and infrequent tyre rotation. Visit a Dunlop Tyre Center to get the best care for your tyre Dubai has to offer!
Tyre with a higher speed rating are best for a desert climate, since higher speeds are related to heat generation in the tyre. Tyres with a higher speed rating can therefore withstand higher temperatures.
