What do tyre load ratings mean

In this case you need inch wheels the possibility of using such wheels. When buying new tyres for your car , you want them to be safe, economic and comfortable. All these features are achievable provided that you know the tyre parameters - this is key when selecting tyres.

To check the parameters you may refer to the manual of your car which provides a detailed description of tyres recommended by the manufacturer. Such information can be easily found on the fuel filler flap, on the pillar behind the driver or on the inside of the driver's door. Using tyres with a load index lower than that specified by the manufacturer is always dangerous. There are quite a few reasons why you should observe the manual guidelines.

Faster tyre wear - Tyres with the wrong load index may wear faster, increasing your car maintenance costs. Risks when driving - Too much load on a tyre may result in the tyre blowout and a consequent accident on the road.

Loss of driving stability - You are likely to experience car handling issues and reduced comfort. Rejected insurance claim - After a collision or any traffic incident, your car insurer may refuse to pay your claim if the car was fitted with tyres not recommended by the manufacturer.

No guarantee - When installing tyres with parameters non-compliant with specifications defined by the manufacturer, the tyre guarantee is void.

Possible fine - A police officer on a routine check may issue a fine if your tyres do not meet the manufacturer's requirements. Modern safety systems installed in cars, such as traction control or ABS , are closely linked with the type of tyres recommended by the manufacturer.

Fitting tyres that do not meet these requirements causes many problems and the risk of losing basic safety while driving. It is possible to mount tyres with higher load rating and speed rating than those provided by the manufacturer. However, is it worth using tyres with higher indices? Remember that using tyres with a lower rating is dangerous and, as such, it is prohibited by law. Make sure that you and other road users are safe. Read the information necessary for selecting correct tyres.

Remember that using tyres with a lower rating is dangerous and, as such, prohibited by law. Read all the necessary information in the tyre load rating table before selecting new tyres for your car or hitting the road with heavier load. Terms and conditions Delivery costs Delivery time. However, these indicators do not reveal anything about the permissible load in kilograms. So this is a useless indicator in everyday life. It is easier to calculate the tyre load rating using our load index table for tyres.

There you can find the maximum load in kilograms for the respective rating. It is a legal requirement that the indicated tyre load capacity is not exceeded. In addition, you avoid the risk of tyre damage.

Your vehicle speed and the air pressure in the tyres also influence the relative indicator of load capacity. Driving at high speed and with heavy loads exerts forces that put a high amount of stress on the tyres.

If the load becomes too great, the tyres can become damaged. Other factors often come into play here, such as the tyre lifespan. The tyre air pressure is important when it comes to the tyre load capacity.

The load capacity of your vehicle gradually decreases as the air pressure reduces. In turn, the load capacity increases as the air pressure increases. However, the recommended guide value should not be exceeded as this can change driving behaviour.

In principle, the following applies: Increasing the air pressure by 0. The information in the load index table for tyres is based on an assumed tyre pressure of 2. However, experience shows that the value is not adhered to in many cars. Is it possible to fit tyres with a higher speed rating and a higher load index than my manufacturer recommends?

Is it possible to fit tyres with a higher load index and a lower speed rating than my manufacturer recommends? Check your vehicle owner's manual to determine the load limits. Overloading your vehicle places stress on your tyres and other critical vehicle components. It can cause poor handling, increased fuel consumption and may cause tyre failure. It can also result in severe cracking, component separation or "blowout. This is the maximum inflation pressure for your tyre.

In most EU countries the minimum tread depth 1. How to read your tyre sidewall markings. Wheel diameter: The diameter height of the wheel in inches. For example, a tyre with a load index of 91 can carry kg of weight.
