Sand Tyre LME7 (E7) Whether to go radial or bias tyres on your site is an important question affecting your tire operating costs. For instance, construction, earth moving, and grading applications that put on relatively high mileage are seeing the benefits of radial tires because they last longer, reduce fuel consumption, and increase the transfer of horsepower to the ground. Radial OTR Tyre Constructed with steel belts to protect the tread area, radials offer enhanced load-carrying capacity and generate less heat when hauling at higher speeds and longer distances. Radial tyres were developed in 1946. There was a need for more flexible tyres, which could absorb shocks generated by road surfaces. These tyres are also more robust, which means machines can be operated at higher capacities. Bias OTR Tyre A radial OTR tire isn’t always the best solution for every job requirement. Bias tires are better for job sites with more stationary work and less travel.
