1.0 Wheel and Tyre Selection

Wheels, wheel fixings and tyres must be considered as ‘safety critical’ parts in all cases. For this reason
they must meet all of the required specification and legislative requirements. Each Group Company must
consider variations in vehicle type and local legislation.

Each Group Company must have a documented list of all vehicles in their fleet that specifies:

 Vehicle type
 Wheel, tyre size and aspect ratio
 Wheel fixing type and size
 Tyre pressures
 Tyre rating (speed and where required load)
 Torque settings (initial, where required, and final stage torque)
 Jacking and lifting support positions

1.1 Wheels

Where wheels are not sourced from the Original Equipment Manufacturer (OEM), Group Companies must
have processes in place to ensure alternative parts are fit for purpose and verified (See Global
Maintenance Standard 4 Parts Management (Including Safety Critical Parts). These must meet or exceed
the specification of the OEM supplied wheels.

1.2 Tyres

Each Group Company must ensure that tyres that are supplied under contract or tyres that are purchased
or leased, are fit for purpose and of the correct specification. For purposes of clarity this must include, but
is not limited to:

 Size
 Profile
 Tread pattern
 Speed rating
 Load rating
 Ply rating
 Load / pressure marking
 Suitability for summer or winter use
 DOT compliance symbol (where appropriate), or local equivalent
 Tube / Tubeless
 Type of construction (Radial or Cross Ply)
 Minimum Tread Depths
 Remoulded / Recapped / retreaded tyres
 Tyre Regrooving

Each Group Company must have an agreed and documented minimum standard for each vehicle type,
and variance thereof, for the vehicles in their fleet.
