Anyone who has ever dealt with the choice of truck tires, analyzing the offers on the market, has come across the so-called fuel-saving lines. Representatives of premium brands especially like to boast about their fuel-saving technologies. Of course fuel economy is a hot topic for carriers, but can choosing the right tires really make a difference? Let’s tackle this with Cordiant.
The fuel economy of a truck depends on many factors and can be divided into two groups: vehicle characteristics and operation. The characteristics of the car include: engine efficiency, aerodynamic resistance of the car, transmission type and parameters, tires, lubricants and other elements, parts and components of the vehicle itself, as well as their technical condition. What proportion of a vehicle’s total fuel consumption do tires have? According to various estimates, the rolling resistance of tires can account for almost 13% of a truck’s energy consumption. It is important to note that failure to adhere to the recommended tire pressure can lead to significant overruns. For example, lowering the tire pressure can add up to 10% to +5% of the total consumption.
If the fuel consumption factors associated with the car are more or less understood and fall within the framework of the vehicle itself, then the operational factors are much more interesting. Operational factors include everything that happens to the vehicle during use, including the environment. Namely: speed, weight, type of road surface, weather conditions, air temperature, wind resistance, traffic, terrain, the number of descents and ascents, curves and turns on the route, driving style and much more, including the daily operation of vehicles funds in each fleet. For example, driving in the rain on wet roads and against headwinds can yield +3 liters extra per 100 km compared to driving on dry roads in clear weather. Speed also has a major impact on fuel economy. At low speeds, drag is negligible, but as speed increases, drag increases and up to 70% of the energy consumed can be consumed. Accordingly, the correct choice of speed modes has a significant impact on overall consumption.
With the theory everything is clear, let’s move on to the practice. You will always find special fuel-efficient tires in the product portfolios of A-brands. The Cordiant Professional truck tire range also includes a dedicated trunk line, which focuses on fuel economy. To answer the question of whether tires can actually save fuel, Cordiant conducted comparative tests between its regional and main tires and also compared its main line with tires in the higher price segment.
The tests were carried out on two vehicles of the same configuration, the mileage of which did not exceed 300,000 km, with a payload of 14 tons. In order to eliminate the influence of the difference in fuel consumption between the cars and to take into account the individual driving style, the tires were changed between the vehicles every race.
In order to obtain accurate results, 18 races were held on two routes: one on highways and one on regional roads. The races were held in different weather conditions.
The highway tests consisted of driving on the road at a constant speed on cruise control without frequent acceleration and deceleration. This nature of the tests allowed the tires to be assessed as objectively as possible in terms of rolling resistance.
In trials on regional roads, the influence of various factors with which carriers are confronted in practice was examined more closely. Different driving styles, traffic, road lighting.
According to the test results, the Cordiant Professional trunk tires showed a saving of 1.6-1.7 liters per 100 km compared to regional tires. When comparing the Cordiant Professional mainline of FL-2, DL-2, TL-1 tires with the premium brand’s flagship fuel-efficient tires, the difference was no more than 0.7 liters per 100 km in favor of the tires of the premium brand. the premium competitor.
Let’s move on to the conclusions. Can tires affect fuel economy? The answer is yes. But! The number of liters saved depends on many factors, and those fleets that focus on long distances will really feel this benefit. It is to them that Cordiant recommends its main line of truck tires Cordiant Professional, which is (in terms of a characteristic like fuel efficiency) on par with premium global brands.
