Tyres Online – Guide to Purchasing the Best Quality Tyres Online

When you enter your sleek or beloved car and drive off to work or to the store, the last thing on your mind is the tyres on your car. Vehicle owners rarely think about the tyres on their vehicles until they are in need of a change or repair. This is where all the trouble begins. Many people who purchase vehicles are not familiar with their own vehicles. They are even more ignorant when it comes to purchasing tyres. If you are lucky, you may know how to change a tyre or be taught by a friend or relative.

However, most people haven’t the slightest idea as to what tyres their vehicles need. If you fall into this category, read on to find out how to buy the best tyres online for your vehicle.

Before you begin shopping for your tyres, it is important for you to realize that you don’t have to purchase the same set of tyres that were fitted on your car when you bought your car. You can go for a different set of tyres. The only restrictions that will be set by your car manufacturer when it comes to tyres are the speed rating and the size. If possible, search through the car’s manual for the speed rating and the tyre size specifications. This will guide you on the size and type of tyre you buy. However, there are unlimited models for tyres online from which you can choose.
The next step is to purchase the tyres online.

For this, you will need to understand the codes and ratings used to categorize the tyres. Tyres are marked with standard markings. This will allow you to choose the right type of tyre for your vehicle. The markings do not vary from one manufacturer to the next. All tyre manufacturers use the same standard ratings within the country of manufacture. You will therefore have to identify the origin of the tyres to understand the tyre code used. The markings are composed of a mixture of letters and measurements in mm or in inches.

Some manufacturers may begin the tyre rating with a letter such as P, LT or ST. This indicates the vehicle class for which the tyres can be used. P, for example, indicates that the tyres are to be used for a Passenger class vehicle while LT indicates a Light Truck. These letters are optional. Many manufacturers do not include them in their codes.
The letter is immediately followed by a three digit number. This three digit number indicates the nominal section width of the tyre. This is the width from one edge to the other at the widest point of the tyre. The measurement is given in millimeters.

The three digit number is immediately followed by a slash. This is simply included for character separation. There is a two or three digit number that follows the slash. This number indicates the aspect ratio. This is the ratio of the sidewall height to the width of the tyre. The ratio is represented as a percentage. If this ratio is not indicated in the Tyre code then it should be assumed that the aspect ratio is 82. Tyre codes indicating an aspect ratio that is greater than 200 signify the actual diameter of the tyre. The measurement is taken in millimeters.

Many manufacturers will include a letter to indicate the construction of the tyre’s fabric. The letter indicates the fabric carcass of the tyre e.g. B indicates a bias belt. This means that the fabric used to make the sidewalls is the same material used to make the tread of the tyre. This will result in a more rigid ride. In cases where these letters are omitted, you can assume that the tyre is a cross ply tire.

The two digit number that follows these letters is an indication of the size of the wheel the tyre is designed to fit. This is one of the most important parts of the code when purchasing tyres online. It will ensure that the tyres you order are the correct size for your vehicle. There are a few tyres that include a three digit number such as 390 indicating that they fit 390mm wheels. However, these tyres are very rare.

The two or three digit number that follows indicates the load index. The last two digits that are combined with a letter indicate the speed rating for the tyre.
