Giti Tire has added 385/55R22.5 and 385/65R22.5 to its recently launched Giti GSR237EVO truck pattern, with the EVO name signifying energy saving solutions through vastly improved Rolling Resistance Coefficient (RRC).
Sitting in the tyre manufacturer’s Combi Road segment, both achieve a B label in RRC, a high-level achievement for a regional steer tyre, while a new tread compound has increased mileage by 20% against identical sizes in the Giti GSR259 portfolio.
The Giti GSR237 EVO in 385/55R22.5 also has an improved load index of 162 to comply with the latest generation truck requirements.
The EVO range was first unveiled at The Tire Cologne in 2024 and came to market earlier this year with the Giti GSR237EVO steer and Giti GDR675EVO drive tyres launched in 315/70R22.5. All products score an A-grade label in exterior noise.
The results have been achieved through new internal compounds with lower hysteresis and advanced tyre curing technology which significantly lowers hysteresis generation to improve the RRC and reduce fuel consumption.
They also feature an advanced profile concept to ensure even wear as well as improved robustness and retreadability.
The tyres are also among the first products to arrive into Europe carrying an RFID chip in the sidewall, which allows whole tyre life monitoring.
Antonio Palummo, Senior Manager TBR – Product Development and Technical Service for Giti Tire, said: “We want the EVO name to become synonymous with fleets who want to easily identify combi road tyres which deliver a lower RRC and fuel saving efficiencies in regional applications.
“That said thanks to the improved RRC over other tyres in the Giti product range, they will also perform well in highway applications. These new wide base sizes also ensure more product can be moved per journey thanks to their higher load capacity.
Development of the Giti GSR237EVO and Giti GDR675EVO was led by Giti Tire’s European Research & Development Centre in Hannover, Germany.
