Introduction

Wheel fitment and security means ensuring there are appropriate management systems to ensure that
wheels are selected, fitted, inspected and monitored to ensure they are secure and meet all legislative
requirements throughout their life cycle.

This standard provides minimum requirements for wheel and tyre selection, fitment, retention and
inspection. Group Companies must have in place management systems to deliver and maintain wheel
fitment and security.

It is the responsibility of the Engineering Director, or equivalent, to ensure that those responsible for
discharging these policies are competent to do so.

Scope and Application of these Requirements

This Global Maintenance Standard sets out the minimum requirements that must be applied throughout all
National Express Group Companies. This is to ensure that all wheels and tyres fitted to vehicles are
selected, fitted, inspected and monitored to ensure they are secure and meet all legislative requirements
throughout their life cycle. In addition to the requirements of this standard, all statutory requirements set by
local and national legislation and regulations must be complied with. It is the responsibility of each Group
Company to identify and apply the relevant legislation, industry codes and standards.

Each Group Company is responsible for incorporating the requirements of this standard into their
management systems and operating procedures. Each Group Company can, of course, exceed the
requirements outlined in this standard, and such good practices should be shared across the Group.
Where Group Companies are already exceeding standards, then these should be maintained.

Each Engineering Director (or equivalent) shall define the person or people within each Group Company
who have the necessary competence to draft the policies identified in this Global Standard.

Wherever possible it is recommended that a peer review of draft standards is carried out across the Group
to capitalise on existing expertise and best practice.

Risks

Wheel and tyre fitment and all associated activities can critically affect the roadworthiness, stability and
driving characteristics of the vehicle, and are therefore of the highest importance. Wheel and tyre fitment
must be deemed as a ‘safety critical’ activity and all policies and procedures implemented in line with this
standard must be effectively managed and enforced at all levels.
