Semi steel tires and all steel tires

1, all steel tire grounding area is large, good adhesion performance, tread slip is small, the ground unit pressure is small, so all steel tire rolling resistance is small, long service life.  

2, semi-steel tire rolling resistance is small, low fuel consumption.  Due to the radial tire curtain layer is less, low driving temperature, heat dissipation, and because of the circumferential deformation is small, so the rolling resistance is 15%-20% smaller than the ordinary diagonal tire, sliding distance is about 25% more, so the use of radial tires can not only improve the speed of the car, but also improve the fuel economy of the car (generally can reduce fuel consumption of 5%-12%).
