Rolling Resistance Not a Big Factor: NHTSA Data
Low rolling resistance is not a major factor to U.S. tire buyers, according to testimony by TIA’s Kevin Rohlwing last week, data NHTSA’s own research shows. Rohlwing, senior vice president of training, testified during NHTSA’s Tire Fuel Efficiency Workshop, held in San Francisco on Feb. 3. “Proper tire inflation, rotation, alignment, and maintenance are still
Rolling Resistance: Just One Part of Fuel Consumption
Not too many years ago, there were three primary criteria for truck tire selection: treadwear, durability, and price. Consolidation of the tire manufacturing industry and advances in materials and process technology have brought the first and second of these much closer together among tire brands, and at much higher levels of overall performance. Some might
Focused Conti Cuts Rolling Resistance by 20%
In designing its latest eco tire range, Continental AG was influenced to a large extent by the changing requirements of its OE customers. As Alexander Luhrs, head of Continental’s press and public relations for passenger and light truck tires, explained at the recent ContiTechnikForum held in Portugal, "the requirements for tire development are in a
STL Upgrades Rolling Resistance Test Capabilities
Standards Testing Laboratories has expanded its rolling resistance testing capabilities and can now handle test tires with up to 10,000 pounds of radial force. STL, which provides rolling resistance testing in accordance with SAE J1269 and ISO 28580 regulations, is capable of testing the latest tires on the market, such as super wide tires
Balancing Rolling Resistance With Other Performance Characteristics
Tires play a vital role in a vehicle’s energy consumption. At normal driving speeds, passenger tires account for up to 20% of a car’s fuel consumption. In other words, in a passenger car, one out of every five tanks of fuel is used to overcome the tires’ rolling resistance. For a commercial truck, it can
Continental: Van Tire Delivers 30% Lower Rolling Resistance
Van drivers looking for a tire designed with rolling resistance in mind have a new option open to them in the form of Continental’s VancoEco range. Developed for vans such as the Mercedes Sprinter, Ford Transit and Volkswagen T5, the tiremaker said the VancoEco reduces rolling resistance by around 30% which equals a 4%
Nokian Prototype Tire Outperforms in Rolling Resistance Test
Nokian Tyres’ new prototype “tire of the future” rolled 64% farther than an eco-oriented summer tire in a recent rolling resistance test conducted at the tiremaker’s logistics center in Nokia, Finland. In the test, conducted with Finnish motor journalists present, a car fitted with three different set of tires The prototype tire, an eco-oriented
Prototype ‘Tire of the Future’ Shows Positive Rolling Resistance Qualities
A prototype summer tire developed by Nokian Tyres is said to have demonstrated 64% superior rolling resistance against a premium ‘eco’ tire in testing conducted by the Finnish tiremaker. In a test held on Mar. 9, a Toyota Prius was fitted with the prototype tires and also with Michelin Energy Saver tires (both the same
Rolling Resistance: What Really Makes a Tire Fuel-Efficient?
res are carbon black and silica.The use of lower levels of filler and larger sized particles result inbetter rolling resistance. Carbon black is predominantly used in tires,but the use of silica has become a primary alternative to improverolling resistance. When silica is used to improve rolling resistance,it is traditionally used with a silane coupling agent,
Outline of New Rolling Resistance and Noise Requirements
A new European Union regulation “concerning type approval requirements for the general safety of motor vehicles,” regulation 316, was recently voted on and passed by a large majority in the European Parliament.
