Giti Tire has added sizes 385/65R22.5 and 13R22.5 to its most recent mixed service launch, the Giti GAM838 next generation steer tyre.
Available alongside 315/80R22.5, which launched in September 2025, the pattern features the latest compound and tread technologies resulting in enhanced mileage, superior grip characteristics and a reinforced tread area to further protect from tearing, cutting and chunking.
The Giti GAM838 is designed for milder operating conditions with 385/65R22.5 offering greater ground clearance and improved capability to manage rough terrain and uneven surfaces, while the 13R22.5 is for more demanding environments and well established in French, Italian and Spanish markets.
Having undergone in-depth field tests with EU fleets to confirm performance levels, the tyre improves mileage, crack and chipping protection by 15% while wet braking, rolling resistance and retreadability, important for circularity, see a performance increase of 10% against its predecessor.
Environmentally the GAM838 has improved Rolling Resistance by one level to Grade C, meaning lower fuel consumption. In addition the new tread compound has reduced high abrasion particle emissions by 20%.
The tyre was launched alongside the Giti GDM687 drive tyre, which carry many of the same features and benefits, with both complementing the popular Giti GAM831 which is designed for more severe usage.
All new Giti truck and bus tyres arriving into Europe carry an RFID chip in the sidewall to make them capable of whole life monitoring.
Antonio Palummo, Senior Manager TBR – Product Development and Technical Service for Giti Tire, said: “The Giti GAM838 has been very well received since its launch with many European customers praising its durability on-and-off road while commentating on exceptional comfort, fuel efficiency and safety. Bringing the new sizes to market now will start to meet the high demand we are receiving.”
“In line with many fleet operators’ commitment to the environment the sustainability credentials of the tyre also stand out, with the lower rolling resistance resulting in a drop in fuel consumption alongside reduced particle abrasion and improved retreading. All of these elements can make a massive difference to an operators’ profit margins.”
The project to create the Giti GAM838 and Giti GDM687 was led by Giti Tire’s European Research & Development Centre in Hannover, Germany.
