How to use tyres

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 new ones or to put new tyres on front axle and outside of the back axle.

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

5, When fitting tyres which have specified running direction, the running direction should be the same with the running direction of 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 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 shining directly upon it and jack it up to prevent crack of tyre surface.

7, Tyre should be inflated according to specified pressure. But when vehicles run on the roads which have arch of more than 4%, tyres on front wheel and inside of the back wheel can be inflated 0.2 -0.35kg /cm2 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 1kg /cm2 more than specified pressure, you must stop vehicle at a shady place. After pressure drops to proper value, start again.

9, "More inflation in winter", "less inflation 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 prolong service life of tyres we recommend to do end to end "X" rotation as regulated when running 8000 -10000km ,and at the same time to check tyres, inner tubes and flaps.

13, When change the tire position, all tires position should be changed at the same time, and the original rolling direction of the tires will be not changed.

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

15, 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.

16, 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 fitted chain may damage sidewalls and treads.

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

18, 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 anticorrosive oil.

How to store tyres

1, Tyres should be stored in a dry warehouse where no direct sunbeam shines inside and without much flowing air, the temperature inside in -10-30oC ,relative humidity is 50-80%,The warehouse should keep distance from places, where power generation equipments exist or zone generates, so as to prevent fast oxidization.

2, The place of store tyres inside the warehouse should keep more than one meter away from heat generation equipments and cannot be put together with oil, acid, alkali and inflammable chemical products.

3,Tyres or tyres fitted with inner tubes inside should be placed vertically on shelf. Tyres' contact position with shells should often be changed at least once in 3 months.

4, Tyres fitted with inner tubes inside should be stored with the surfaces of inner tube with talcum powder applied and inflated with low pressure.

5, When inner tubes are being stored separately they should be inflated and hanged on a frame with a semicircle and their hanging positions should often be changed to prevent deformation or fold occurring.

6, When store tyres packed with wrapping material, put them on shelfs don't peel the wrapping material away.

7, Tyres should be stored in lots according to production date or store date first in and first out.
