Wide-base mixed service tyre for steer and trailer axles in on/off-road conditions, supporting load capacity, casing protection, and consistent wear across demanding operating cycles.

Designed for fleets operating on sealed and unsealed surfaces, the Giti GAM851 supports stable wear performance and casing protection under high-load conditions. Its wide-base design and tread structure contribute to even wear and consistent removal intervals, supporting maintenance planning and Cost Per Kilometre (CPK) management in mixed service operations.

  • Deep tread design supports extended removal mileage in mixed service use
  • Three-groove tread pattern promotes even wear across the footprint
  • Wide-base design improves load distribution and stability under load
  • Anti cut compound reduces damage from rough surfaces
  • Sidewall protection ribs reduce casing damage from impacts and curbing
  • Steer and trailer fitment supports flexible fleet configuration

Casing construction supports consistent
The casing structure spreads load evenly across the tread surface. This helps reduce uneven wear and extends service life during repeated on- and off-road use.

Three groove tie bar design improves rig
Three grooves with tie bars stabilise tread blocks under load. This reduces movement, lowering noise and improving durability on mixed surfaces.
giti gam deep tread design
Deep tread with anti cut chip compound
A deep tread works with a reinforced compound to resist tearing. This helps maintain tread integrity when operating on gravel, debris and uneven ground.
