  • All Position
  • Mixed Service
All-position mixed service tyre designed for heavy load operations across construction, quarry, and regional on/off-road environments requiring durability and consistent wear.

Engineered for fleet operations exposed to demanding loads and mixed surfaces, the Giti GAM839 supports stable wear performance and casing strength under continuous stress. Its construction and tread design assist in maintaining removal mileage while contributing to predictable maintenance cycles and improved Cost Per Kilometre (CPK) across heavy-duty applications.

  • Reinforced belt construction improves resistance to punctures under load
  • Thick cord casing supports durability in continuous heavy-duty cycles
  • Central V-groove reduces stone retention and casing damage risk
  • Shoulder grooves assist heat dissipation and wear stability
  • Optimised tread rigidity promotes even wear across service life
  • All-position design supports flexible fleet fitment strategies

giti gam optimised rib ratio
Optimised rib ratio balances tread press
The rib ratio helps distribute load evenly across the tread surface. This reduces uneven wear and supports longer service life during repeated highway and site driving.
giti gam reinforced casing construction
Reinforced belt construction protects ca
The belt structure strengthens the casing against debris and sharp surfaces. This lowers puncture risk when operating on gravel roads or construction access tracks.
giti gam water resistant compound
Durable compound resists cuts and damage
The tread compound is designed to handle abrasion from rough surfaces. This helps maintain tread condition and extend use across mixed on road and off road routes.
