Tires

Tires are an important part of the drive- train and the articulated hauler concept.

Advantages • Large and wide tires for good comfort, low ground pressure and excellent off-road mobility. • Radial tires give long service life and low hourly cost. • Large selection of tires suitable for all operating conditions and applications.

The tire has to perform a variety of tasks and these tasks change during a work cycle and in different operating conditions. Examples of these tasks are: • Being capable of carrying the total hauler weight • Provide good rimpull (traction) and be self-cleaning • Reject heat generated during long, high speed hauls • Have good protection against tire cuts

• Provide a comfortable ride • Provide low ground pressure • Provide good stability and long service life

To be able to handle these tasks, the A25D is standard- equiped with wide base tires and the A30D is standard- equiped with low-profile tires. Most of the tires are avail- able in two classes, E2/3 tires for normal applications (general purpose tires) and E4 tires for more demanding applications, for example, where better cut protection is needed. E2/3 Wide base 80% profile tire with standard tread depth (100-125%). A general purpose tire suitable for almost all articulated hauler applications. • Good self-cleaning and traction • High average speeds (TMPH index) • Long tread life E4 Wide base 80% profile tire with deeper tread (150%), suitable for work sites with relatively well-maintained haul roads and abrasive environments, i.e. gravel pits and quarries. • Good cut protection • Good comfort • Extra long tread life 65-series (low-profile) 65% profile is wider than 80% profile but with the same diameter, suitable for almost all articulated hauler applica-
