The basics of truck and bus tyres

Introduction to tyre use

A tyre choice must comply with the law and the recommendations of the vehicle or tyre manufacturer, or an official body (size, load index and speed rating, structure, etc.).

• You need to take account of the conditions the tyre will be used in so that its performance levels meet hauliers' expectations.
• If changes are made to an original vehicle component, you should check that the proposed solution complies with current legislation and the manufacturer's requirements and recommendations (see the regulations in force in the country). In some countries, the modified vehicle must receive an administrative approval.
• Any tyre that is second-hand, used or has been involved in an accident must, prior to fitting, be checked carefully by a professional to ensure the safety of the user and compliance with current regulations (see Best practice for tyre fitting and inflation).
• Tyre misuse or an unsuitable tyre choice can also help cause some mechanical parts to wear out prematurely.
