There are mainly four types of tyres: summer, winter, all-season, and performance.

• Summer tyres are designed for warm weather and provide good grip on dry roads.

• Winter tyres are made of a softer rubber compound to maintain flexibility in cold temperatures.

• All-season tyres are a compromise between summer and winter tyres, suitable for moderate weather conditions.

• Performance tyres offer enhanced grip and handling for high

Standard PSI in truck for loading or unloading varies depending on the type of truck and the weight of the load.

• Standard PSI for loading or unloading in trucks typically ranges from 80-100 PSI.

• It is important to check the manufacturer's recommendations for the specific truck and load being transported.

• Overinflating or underinflating tires can lead to safety hazards and decreased efficiency.

• For example, a heavy-duty tru...read more

PSI stands for pounds per square inch, a unit of pressure measurement commonly used in engineering and physics.

• PSI is used to measure pressure in various systems, such as in hydraulic systems or tire pressure.

• 1 PSI is equal to 6894.76 pascals.

• PSI is commonly used in the United States and other countries that use the imperial system of measurement.

PSI measurement instruments include pressure gauges, pressure transducers, and pressure sensors.

• Pressure gauges

• Pressure transducers

• Pressure sensors

There are various types of trucks available in India, including heavy-duty trucks, medium-duty trucks, light-duty trucks, and specialized trucks.

• Heavy-duty trucks: used for long-haul transportation of goods, such as Volvo FH, Tata Prima

There are three types of wear: abrasive, adhesive, and surface fatigue.

• Abrasive wear occurs when hard particles or surfaces rub against a softer surface, causing material loss.

• Adhesive wear happens when two surfaces stick together and then separate, causing material to be pulled off.

• Surface fatigue wear occurs when repeated stresses cause cracks or other damage to the surface of a material.

• Examples of wear include eros...read more

Heel and toe wear in a tyre can be identified by examining the tread pattern.

• Heel wear occurs on the outside edge of the tyre tread and is caused by excessive cornering.

• Toe wear occurs on the inside edge of the tyre tread and is caused by misalignment of the wheels.

• To check for heel and toe wear, examine the tread pattern and look for uneven wear on the edges of the tread.

• If heel and toe wear is identified, it is impor...read more

Use a tire gauge to measure the pressure and depth of the tire tread to determine the tire number.

• Use a tire gauge to measure the pressure of the tire.

• Measure the depth of the tire tread using a tread depth gauge.

• Refer to the tire manufacturer's guide to determine the tire number based on the pressure and tread depth measurements.

• Alternatively, take a picture of the tire number and use it for reference.
