Can you choose tires? The right may help you save fuel


Labels and ratings rolling resistance

And as the right "soft" tires to choose? Make it easy labels that are now mandatory located on each new tire. The label is in addition to other states from rolling resistance tires, which are directly related to fuel consumption. "The plate rolling resistance evaluated by the letters A to G. The difference between the best and the worst is yet rated 0.66 liters of fuel per 100 kilometers," says Jan Foltán from an online store Get tires.

Lower power consumption the also "eco" tires in the manufacture of the emphasis on effective reduction in rolling resistance. But even so, the drivers should be careful and check their other properties. Low rolling resistance is can cause poor handling, especially lengthening stopping distances.

The narrow width and low profile

Fuel consumption is also affected by tire sizes. "To reduce consumption will reach by choosing narrower tires. Reported that about 10 mm narrower tire us reduce fuel consumption by 0.1 liters. Caused is again rolling resistance, which is at the lower narrower tires," explains Foltán.

Similarly, fuel consumption also decides profile tires, which indicates the ratio of width to its height tires. The lower profile, the lower should be the rolling resistance and hence fuel consumption.

The correct tire pressure

Provided you have selected the right tires, you need to also pay attention. That means - proper inflation. "Fuel consumption is increasing especially in under-inflated tires that have higher rolling resistance. Only slightly deflated by one-tenth increase fuel consumption by one percent," says an expert.

Guideline tire pressure can be found for example on the fuel cap. You measured should be at least once a month. Savings can be up to five percent of fuel.

At the winter in the summer Sun

Many drivers naively believes that commuting sample of winter tires in summer significantly save. In fact, driving on winter tires at high temperatures significantly increases fuel consumption by up to 10 percent compared to driving in summer. This is due to the softer compound used for the production of winter tires and the associated higher rolling resistance.
