Basic knowledge of Truck & Bus Radial Tires
Sidewall Marking
The sidewall of a tire contains important information that can tell you a lot about the tire’s specifications and capabilities. Here are the 9 key markings you will find on a tire’s sidewall
By means of Toyomoto Know-how, it could help:
- Improvement in durability, wear resistance, and the strength of belt, carcass and bead;
- Increase the retreadability because of the improved durability;
- Tire service lifetime is also increased due to the durability.
These above are the status of foot pints of tires under different pressure of inflation.
For Standard pressure, refer to the marking in the tire sidewall.
For Standard pressure, refer to the marking in the tire sidewall.
The relationship between pressure and driving mileage
Comparison of TT and TL Tires
Heat Radiation
Narrower Not Good for cooling
Anti-Puncture
Air leaking Fast
Easy Control
Balance
More Components and likely folding of tube can result in unbalancing
Weight
Tube (3.2Kg)
Flap (2.5Kg)
More Weight
Heat Radiation
Wider Excellent for cooling
Anti-Puncture
Air leaking Slow
Easy Control
Balance
With no tube and flag, it can keep good balancing
Weight
Without tube and flag, the weight is less and it is fuel conserving
The techniques of tire using
- If the vehicle is operated at high-speed for long distance, it should be stopped for releasing warm but not be emitted pressure and not be sprinkled cool water on it.
- The vehicle should be avoided violent acceleration, emergent brake and sharp turns, To prevent over-speeding, over-loading.
- If the road is bad, slow down, avoid tire be impacted by sharp objects.
- The tire should often be inspected, as soon as the damages to be found and repaired immediately.
- The tire should be stopped using when the tire wear to the wear mark.
- The retreaded tie should not be used as steering tire in order for security of the vehicle.
- After high speed for 1-2 hours, it should rest 15-20 minutes and check the tire.
Load
- The load of tire should be suit with the current national standard, no overloading.
- Overload will shorten tire life. Tire will build up heat quickly, cause tire early damage (as shoulder separation and bead explosion).
- The tire of high ply rating or heavy load can not in high speed running for long time.
- The goods load should be placed symmetrically in order to avoid one tire takes too much load.
