Reinforced tire for tow truck trailer 155/70 R13 79N XL WANDA WR301
Tire size 155/70 R13 .
The described tire has a speed index N , which means that the maximum speed at which this tire can be driven is 140 km/h .
The load index of this tire is 79 , which means its maximum load is 437 kg .
The tire has the following classes on the label: D (fuel efficiency), C (wet grip), 70 dB (noise level)
Fuel efficiency determines the rolling resistance of a tire. The lower it is, the lower fuel consumption and energy demand, as well as the lower environmental impact in the form of lower CO 2 emissions. The rating is expressed in classes from A to G. Increasing the class by one translates into savings of approximately 0.1 liter of fuel per 100 km. The difference between class G and A reduces fuel consumption by approximately 7.5%.
Wet grip is a key factor in a tire's safety level. Its value primarily informs about the length of the braking distance on a wet asphalt surface. The rating is expressed in classes from A to G. The difference in braking distance between adjacent classes in wet conditions and an initial speed of 80 km/h is between one and two vehicle lengths of approximately 3.0-6.0 meters, approximately 4.5 m. The difference in braking distance between classes A and F is over 18 meters.
The noise level parameter determines the noise produced by the tire when rolling on the road surface. It is measured in decibels (dB). The noise emitted by tires affects the overall sound intensity of the vehicle, and also affects driving comfort and the environmental impact of the noise produced. For example, the difference between 75 dB and 72 dB may seem small, but in reality, a 3 dB difference reduces the noise level by half.
