Features of Haida Mine Truck/TBR Tire HD 788

Like Haida's other mining tires, the HD788 is designed with high-temperature-resistant apex compounds. This design can reduce the possibility of bead deformation of the truck under high-load conditions, improve the safe driving performance of the tire, and prolong the service life of the tire.

HD788 tires use high-quality rubber with special reinforcement and vulcanization system. We use a proprietary mixing process to improve the cutting and puncture resistance of the rubber. This makes the tire HD788 the best companion for Truck /TBR. Great for driving in the mines.

Main Sizes and Parameters of Haida Mine Truck/TBR Tyre HD788

The tires‘ sidewalls will be marked with various parameters of the tire, such as tire size information, load rating and speed rating, etc. The following are the parameters of Haida Mine Truck/TBR Tire HD788.

Tire speed class

The tire speed rating refers to the maximum speed at which the tire can carry a specified load under specified conditions.

Tire speed grades are available from A1-A8, B, C, D, E, F, G, H, J, K, L, M, N, P, Q, S, T, U, V, W, Y, ZR 30 kinds.

The corresponding speed of the specific tire speed level is as follows:

1. The speed level is A1, which stipulates that the certified speed is 5km/h.

2. The speed level is K, which stipulates that the certified speed is 110km/h.

3. The speed level is A2, which stipulates that the certified speed is 10km/h.

4. The speed level is L, which stipulates that the certified speed is 120km/h.

5. The speed level is A3, which stipulates that the certified speed is 15km/h.

6. The speed level is M, which stipulates that the certified speed is 130km/h.

7. The speed level is A4, which stipulates that the certified speed is 20km/h.

8. The speed level is N, which stipulates that the certified speed is 140km/h.

9. The speed level is A5, which stipulates that the certified speed is 25km/h.

10. The speed level is P, which stipulates that the certified speed is 150km/h.

11. The speed level is A6, which stipulates that the certified speed is 30km/h.

12. The speed level is Q, which stipulates that the certified speed is 160km/h.

13. The speed level is R, which stipulates that the certified speed is 170km/h.

14. The speed level is A8, which stipulates that the certified speed is 40km/h.

15. The speed level is S, which stipulates that the certified speed is 180km/h.

16. The speed level is B, which stipulates that the certified speed is 50km/h.

17. The speed level is T, which stipulates that the certified speed is 190km/h.

18. The speed level is C, which stipulates that the certified speed is 60km/h.

19. The speed level is U, which stipulates that the certified speed is 200km/h.

20. The speed level is D, which stipulates that the certified speed is 65km/h.

21. The speed level is H, which stipulates that the certified speed is 210km/h.

22. The speed level is E, which stipulates that the certified speed is 70km/h.

23. The speed level is V, which stipulates that the certified speed is 240km/h.

24. The speed level is F, which stipulates that the certified speed is 80km/h.

25. The speed level is W, which stipulates that the certified speed is 270km/h.

26. The speed level is G, which stipulates that the certified speed is 90km/h.

27. The speed level is Y, which stipulates that the certified speed is 300km/h.

28. The speed level is J, which stipulates that the certified speed is 100km/h.

29. The speed level is ZR, which stipulates that the certified speed is above 240km/h.

30. The speed level is A7, which stipulates that the certified speed is 35km/h.

The speed level of our Haida Mine Truck/TBR Tire HD788 is F, which means that its certified speed is 80km/h. That is, the speed of the vehicle cannot exceed 80KM/h. If the speed is exceeded, it will increase the wear of the tires and increase the chance of a tire blowout, which is very dangerous. Of course, in the mines in Kenya, it is impossible for us to drive the trucks so fast.
