Welcome to ZAOZHUANG DINGNA INTERNATIONAL TRADE CO., LTD. Please contact with us and let's work together. We believe that we will establish a long-term good business relationship through discussion and cooperation.
 

1.Tyre and Rim

(1)Check carefully before tyre mounting to see if the rim sizes are identical to thosemarked on sidewalls.
(2) The tyre should be fitted as much as possible to standard rims or allowable rim range.(3) The tyre should not be fitted to deformed rims or non-conformity rims.Warning:
Deformed rims or non-conformity rims will result in premature tyre toe failure or blow outto hurt People.

2.Inflated Pressure

(1)Rules should be followed to inflate the tyre (Figure1)(2)lt is not appropriate to inflate the tyre over pressure and then release the air tostandard pressure.
(3)Check the tyre pressure regularly and replenish when the air pressure is not foundSufficient.
Warning:Tyre under-pressure will cause decreased loading capacity, easy cord breaking anddangerous blow out ,Tyre overpressure will cause cord strength loss and dangerous blow out.

3.Load

(1) Select the tyre of correspaonding ply rating and load based on the vehicle's standard
loading capacity.(2) The tyre of low ply rating can not bear high load. The tyre load mn not be increasedby the increase of inflated pressure.
(3)The load should be distributed evenly on the vehicle.(Figure2)Warning:Overload will cause a serious injury to the tyre or the People. The vehicle with the loadunevenly distributed will cause some of tyres serious overload, which is one of the factorscausing accidents.

4.Speed

The tyre should match the vehicle in operating speed and operate in the range ofspecified speed for vehicle.
Warning:Over speed will cause quicker tread wear, rapid heat build up, tyre strength deterioration.separations and even tyre blow out.

5.Tyre Mounting
(1)Tyres of same specifications, ply ratings and tread patterns must be mounted on thesame axle. The original tyre differs from the replaced tyre in height not more than 3%.
(2)Dual tyre rim ventilating holes should be in alignment with each other. Tyre valvesshould be positioned at 180 to each other. Dual spacing should be more than 20mmunder static load.
(3)Tyre toe-in should be adjusted to a standard value.(4)When the old tube is used, its outer circumference should not be over 92% of theinner circumference of the tyre. lt is recommenbed that the old tube with more than 2repair patches should not remain in use.(5)The rim should be tightly and evenly bolted into position.(6) As to tyres of directional tread patterns, the direction marked on sidewalls should beidentical to the direction of vehicle travel.Warning:
Tyres of diferent specifications, ply ratings and tread patterns mounted on the same axlewill deteriorate comprehensive tyre performances. Smaller dual spacing will cause easyheat build up due to the friction between two tyres and cause premature tyre failure. Thetyre toe-in poorly adjusted will cause vehicle,s poor directivity, tyre side slip. severe treadwear and increased fuel cost. Too big circumference of the old tube will cause the tubefolded inside the tyre and tyre blow out.

6.Pre-ride of tyres
When new tyres have been mounted, the pre-ride should be taken below 50km/h for200km for normal tyres .Through the pre-ride newtyres will adapt to deformation, remove the stress caused during manufacturingdecrease heat build up and extend tyre performance life.

7.Others
(1)Quick start up, urgent braking, sharp turning, striking by sharp obstaclescontacts with corrosives and oil contaminants, operation in high temperature, etc.
will cause premature tyre failures.(2)Tyres should be well maintained and regularly shifted (Figure 3). The sharpobstacles punctured into lyres or the stones clogged in tread channels sbecid beremoved immediately.
(3) When the tyre tread has worn out to the extent specified, stop using it.(4) lf there is any problem regarding tyre quality, please do not hesitate to contactthe tyre dealers or us to enable solving the problems immediately.
