Cycling tyre manufacturer Maxxis is set to upgrade its gravel tyre portfolio by introducing its new HYPR-X compound.

The new formulation combines technology from two existing Maxxis compounds: the low-rolling-resistance HYPR for road cycling and the race-winning MaxxSpeed for mountain biking applications.

According to Maxxis, the enhanced versions of its Receptor, Reaver, Rambler, and Ravager models will deliver “19 per cent better cornering traction and 25 per cent less rolling resistance” compared to their predecessors.

Technical improvements extend beyond the new compound. Maxxis implemented a stronger nylon material for the 120 TPI casing to increase tread durability. Sidewalls will incorporate the company’s EXO Protection technology to guard against cuts and abrasions. All models will be tubeless-ready.

The company has also refreshed the aesthetic design of these tyres, featuring updated branding on hot patches with grey and orange accents. In line with sustainability initiatives, the new range will ship in recyclable paper packaging, reducing plastic waste.

The phased rollout begins with the Reaver and Rambler models in 700X45C size, with additional sizes becoming available throughout the next three months. The Ravager and Receptor range is scheduled for release in the third quarter of 2025.

Maxxis has directed customers to contact local dealers or visit their website for information on availability as products are released throughout the year.

Global Rubber Industries (GRI) has reported higher traction, productivity and fuel efficiency for its GREEN XLR vFLEX 70 agricultural tyres than an established variable-footprint (VF) benchmark, following independent testing by Germany’s DLG TestService.

The Sri Lanka-based tyre manufacturer received the DLG Approved Quality Mark under Test Report 7616 after its tyres were assessed for traction, productivity, fuel efficiency and soil preservation at the testing organisation’s facility in Groß-Umstadt, Germany.

The tests used a John Deere 6R 215 tractor fitted with GRI GREEN XLR vFLEX 70 tyres measuring 710/70 R 42 on the rear axle and 600/70 R 30 on the front axle. The tyres were compared with an established VF reference tyre.

The results showed that the GRI tyres delivered 17.2 per cent higher traction and 3 per cent greater productivity than the benchmark. Hourly fuel consumption, measured in litres per hectare, was 3 per cent lower.

DLG concluded: "Overall, the GRI Green XLR vFLEX 70 impressed in the tested trials, particularly in terms of traction, productivity, and energy efficiency."

The productivity assessment measured hectares covered per hour, taking into account drawbar force, driving speed and wheel slip.

GRI said a three percent productivity improvement could translate into approximately 120 additional hectares covered over 1,000 operating hours, assuming a constant work rate of four hectares an hour. The company described this as an illustrative calculation rather than a measured test result.

The fuel-efficiency results also indicated potential operating savings. Based on an illustrative consumption rate of 20 litres per hectare, a 3 per cent reduction would save approximately 0.6 litres per hectare. Across 1,000 hectares, this would amount to about 600 litres.

GRI estimated that the saving would be worth approximately EUR 900 at a fuel price of EUR 1.50 a litre. It stressed that actual savings would depend on operating conditions, fuel consumption and prevailing fuel prices.

The DLG assessment also examined soil protection. However, the findings were only partially conclusive because usable measurements were available from a soil depth of 20cm under the selected test conditions.

Suresh Damodaran, Head Of Technical at GRI, said the independent assessment provided farmers with measurable evidence of the tyres' performance.

"These results are an important milestone for GRI and a clear validation of what our engineering teams have been working toward," said Damodaran. "Independent testing by DLG now gives farmers measurable evidence of how our tires perform in the field."

He added: "For farmers, the real value lies in what these numbers mean in the field," Damodaran added. "Stronger traction, higher productivity and lower fuel consumption all contribute to more efficient operations and better returns on their equipment. Our objective is not simply to manufacture high-performance tires, but to develop solutions that deliver measurable value to the people who depend on them every day."

GRI said the findings reflected its engineering capabilities in the agricultural tyre segment. It also noted that total cost of ownership would depend on other factors, including purchase price, service life, maintenance and operating conditions.

Global Rubber Industries manufactures specialty tyres for the agriculture, construction and material handling sectors. The company operates tyre production and mixing facilities in Sri Lanka and has a presence in more than 85 markets worldwide.

Continental has secured original-equipment approval for Volkswagen's new ID. Cross, an all-electric compact SUV that will leave the factory fitted with the EcoContact 7 summer tyre in 17-, 18- and 19-inch dimensions. For colder conditions, Volkswagen recommends the WinterContact TS 870 P, while the 18-inch AllSeasonContact 2 is suggested for motorists favouring a single year-round set.

Engineered for low rolling resistance and high mileage, the EcoContact 7 supports energy-efficient, cost-effective motoring. Its Smart Energy Casing technology employs innovative materials in the carcass, inner layer and sidewall to cut internal friction, while an Aerodimple sidewall structure reduces air turbulence behind the tyre and thus aerodynamic drag. A Silent Pattern tread design also dampens rolling noise, especially at city speeds.

The WinterContact TS 870 P relies on its tread pattern and sipe layout for secure grip on snow and ice. The AllSeasonContact 2, meanwhile, offers dependable traction on dry and wet roads as well as in wintry conditions. Approved fitments span the EcoContact 7 in 225/55 R17 97T FR, 225/50 R18 95V and 225/45 R19 92T FR, plus the AllSeasonContact 2 and WinterContact TS 870 P, both in 215/50 R18 96T XL, across numerous countries.
