Eco-Friendly Tires Do Matter, Says Tire Rack

Many tire companies claim their tires are eco-friendly, but recent Tire Rack testing revealed just which brands deliver real-world performance.

Following extensive testing at its South Bend, Ind., test facility, Tire Rack published a comprehensive report analyzing the effectiveness of low rolling resistance tires. In the report, Tire Rack confirmed that using LRR tires is an effective way for consumers to save money while reducing carbon emissions through increased fuel efficiency.

“Low rolling resistance tires represent the most environmentally-focused development in tire technology today,” said John Rastetter, director of tire information at the Tire Rack. “Every gallon of gasoline saved not only reduces each driver’s personal fuel costs and America’s dependence on foreign oil, but it also releases 20 fewer pounds of CO2 gas into the atmosphere from the tailpipe. Our tests proved that vehicles equipped with these tires can achieve better fuel economy.”

Tire Rack conducted a Real World Road Ride Economy Run to determine whether lower rolling resistance tires are effective at increasing fuel efficiency.

The test used a small fleet of Toyota Prius hybrids outfitted with the Goodyear Integrity all-season radials as a baseline. Then it compared the fuel efficiency and traction of other eco-friendly and standard tires against that baseline. Each tire was driven more than 550 miles on expressways, highways and side roads.

Tire Rack said the baseline Prius achieved 51.4 miles per gallon.

(offset 6% for Prius Summer E10 regular grade fuel).

In the case of the Prius, the difference between the lowest and highest recorded miles per gallon would result in an annual difference of about 21 gallons of regular gasoline consumed at a cost of about $52.50 (at $2.50/gallon) for drivers traveling 15,000 miles a year, Tire Rack said.

The fuel economy recorded for each tire and its relative position compared to the Integrity tire’s average is available at www.tirerack.com/mpgtest.

“While tires have always played an important role for all types of drivers, our test results show tire manufacturers have successfully added some green to the traditional round and black,” said Rastetter.

GRI recently conducted programs in Sri Lanka to empower women and motivate children under its Green x Circle initiative. The company said these endeavors aimed to address the needs of the community, focusing on both women empowerment and youth motivation.

GRI recently organized a training program titled "Management of household finance under current economic conditions" at the Ingiriya Rubber Collecting Center in Sri Lanka, South Asia led by Shashika Nimali, an NLP practitioner and life coach. The company said this initiative provided women in the industry with essential skills and knowledge to effectively manage household finances. GRI's tailored training sessions equipped participants with tools for informed decision-making, ultimately fostering greater financial security and independence, the company said.
