1 The large-volume main block design and intermediate closed connection design improve the puncture resistance and explosion resistance under extremely harsh road conditions.

2 The design of the bottom step of the trench with the stone discharge structure provides good stone resistance and effectively prevents puncture injuries at the bottom of the trench.

3 Deep groove heat dissipation groove and heat dissipation round hole design of the shoulder effectively increase the heat dissipation performance of the shoulder block.

4 Deepen the depth of the pattern, widen the driving surface design, increase the grounding area, make the grounding more uniform, and reduce irregular wear.

5 Strengthen the crown structure, effectively improve the anti-explosion performance of tires, and reduce the problem of tire crown explosion and top explosion.

6 Enhanced toe design and tear-resistant triangle formula reduce toe deformation and provide excellent load-bearing performance.

7 The tread adopts ultra-gnawing and puncture resistant formula to enhance the wear performance of harsh road surfaces and greatly improve the mileage of tires.

Our Service Steps

  • Step 1:

    The fitter will get the new tires and wheels ready.

  • Step 2:

    The diameter of the new tire should match the diameter of the rim, and it should be approved for use with the vehicle. Rims should be the correct size, in perfect condition, and free of rust. They must not be damaged, deformed, or worn.

  • Step 3:

    Moving on to the tire beads, the fitter will coat the beads and the rim with fitting lubricant as recommended by the tire manufacturer. Then he will use the tire spreader to mount the tire onto the wheel.

  • Step 4:

    Next comes the inflation of the tire. For the duration of this stage, the wheel must remain firmly secured on a mounting machine. Inflating an unsecured tire is dangerous. The fitter will be aware of this; it’s also why he keeps a reasonable distance from the tire during inflation. Typically, he will use a sufficiently long, secured extension hose with an integrated pressure gauge, and he won’t be bending over the tire as it fills up with air.

  • Step 5:

    Once the beads of the tire are seated correctly on the shoulder of the rim, the fitter will increase the tire pressure to achieve a firm grip on the flanges of the rim. This fitting pressure shouldn’t exceed more than 150% of the maximum pressure recommended by the manufacturer. Next, the fitter will adjust the pressure to the operating pressure as specified by the vehicle manufacturer.
