For better performance of our tires please follow the following instruction :

1. Tyres must be fitted on specified vehicles and rims.

2. On an axle should fit tyres of the same size, brand, dimension, ply-rate, inflation pressure and tread pattern.

3. When fitting new tyres on a vehicle we recommend to replace all the old tyres with the new ones or to put new tyres on front axle and outside of the back axle.

4. When back axle uses the dual spacing should not be less than 20 mm and not more than 35mm and the openings on the wheels should be in alignment.

5. When fitting tyres which have specified running direction should be the same with the running of the wheel. When these kind of tyres often run on hard road the tyres on the front wheels can be fitted in opposite direction in order to reduce rolling resistance and save fuel.

6. Tyres fitted on a vehicle must be keep inflated. If you will not operate a vehicle for more than one week please leave it in garage or a shady place avoiding sunbeam shinning directly upon it an jack it up to prevent crack of tyre surface.

7. Tyre should be inflated according to specified pressure. But when vehicle run on the road which have arch of more than 4% tyres on front wheel and inside of the back wheel can be inflated 0.2-0.35kgf/cm less than specified pressure.

8. When vehicles run for long distance, tyre inflation pressure should often be checked, especially in summer when you find pressure 1 kgf/cm more than specified pressure, you must stop vehicle at shady place. After pressure drops to proper value, start again.

9. “More inflation in winter”, “less winter in summer”,”deflation midway”can never be used.

10. Tyres load which should be calculated according to maximum load of single tyre, cannot be exceeded. Goods on vehicle should be placed evenly.

11. When vehicles run on bad and complicate roads their running speed should be reduced, stop run up and down a slope and corner slowly especially when vehicles cross railway and rut. When a vehicle running on road with arch surface you should drive it in the center of the road to prevent one side wear.

12. According to test reports tyres on front wheel wear 20-30% less than those on back wheel. In order to prelong service life of tyres we recommend to do end to end “X” rotation as regulated when running 8000-10000 kms and at the same time to check tyres, inner tubes and flaps.

13. When a vehicle has stopped in cold weather for a long time and temperature of tyres is less than minus 30-40C, start it smoothly and in the first 20-30 minutes run it slowly, 5-7 km/h. After tyres warm up return to normal speed.

14. When modify carriage or change distance between two axles or add more parts on a vehicle, each tyre’s load capacity on front and back axles must be taken into account so as not to cause partial overload.

15. When chain up tyres, both sides should be chained. Take off chains as soon as vehicle passing through slippy road. Too loose or too tight fitting chain may damage the sidewalls and treads.

16. Tyres appearance should be checked. As soon as cracks, pierced holes are found they must be repaired immediately so as to prevent damage parts increasing.

17. Tyres should be fitted on standard rims. The edge of rims ( or lock ring) should be cleaned periodically to remove rust on it and apply anti corrosive oil.
