High Wearable Trailer Tires 12R22.5 Truck Tires Lower Rolling Resistance
Features
This truck tire of 12R22.5 with all-steel structure, there is 1 ply steel belt on tire sidewall, and 4 wire belts on the tread. It has four straight grooves with providing better handling and low rolling resistance which is suitable for the trailer axle of long haul trucks, is also can be for the steering axle of the trucks. There are 3 sizes of 22.5-inch rim diameter being available: 12R22.5, 295/80R22.5 and 315R/80R22.5.
The applied of high wear resistance tread compound and wider rib tread of outboard shoulder, with improving the even wear, and service mileage is increased more than 20 %.
The S type variable angle under the bottom grooves, which preventing the stone retention in the grooves, and promotes self-cleaning ability.
The applied lighten and stronger material in the skeleton of carcass, reducing the weight of this trailer tire which is based on without scarifying the safety performance, and saves he consumption of fuel to protect the environment.
And the robust of tire casing, makes this truck tire is possible to be retreaded after the tread being worn out.

Application
For these truck fleets with delicacy management, their tractors are not permanently match with the specific trailer. Typically constructed, the trailer is be hauled to the warehouse to wait for the unloading and reloading. Trail tire, which been mounted on the trailer axle, is far away the pilothouse, and get less attention from the driver and manager of truck fleets.
Except of those trucks with heavy-duty, to optimize the rolling resistance and mileage is main two performances of trailer axle part of vehicles, and about 40% the contribution of the tires to the trucks’ mile-per gallon is contributed by the trailer tires.
Fuel efficiency is main feature of this trailer tire of 12R22.5. The application of low rolling resistance provides lower rolling resistance, and optimized geometry of tread pattern, to ensure the footprint being consistent stability, and promotes wear-ability.
