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.

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

• 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

• Medium-duty trucks: used for local transportation and delivery, such as Ashok Leyland Boss, Mahindra Furio

• Light-duty trucks: used for small-scale transportation and delivery, such as Tata Ace, Mahindra Bolero Pickup

• Specialized trucks: used for ...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 important to address the underlying cause to prevent further da...read more

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 erosion of a riverbed due to abrasive wear, scuffing of a shoe...read more

There are numerous tyre brands in India, with both domestic and international companies competing in the market.

• There are over 40 tyre brands operating in India.

• Some popular tyre brands in India include MRF, CEAT, Apollo, Bridgestone, Michelin, and JK Tyre.

• These brands offer a wide range of tyres for various vehicles including cars, motorcycles, trucks, and buses.

The type of tread pattern in a tire affects its performance on different road surfaces and in various weather conditions.

• Tread patterns can be categorized into different types such as symmetrical, asymmetrical, directional, and multi-directional.

• Symmetrical tread patterns provide good all-around performance and are commonly found on standard passenger tires.

• Asymmetrical tread patterns have different tread designs on the inner and outer sides of the tire to optimize performanc...read more

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-performance vehicles.

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 truck carrying a heavy load may require higher PSI compared t...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.

Steering and suspension system in automobile are responsible for controlling the movement and stability of the vehicle.

• Steering system helps in changing the direction of the vehicle while suspension system ensures smooth ride and stability.

• Steering system consists of components like steering wheel, steering column, steering gear, and tie rods.

• Suspension system consists of components like shock absorbers, springs, struts, and control arms.

• The suspension system also helps in ma...read more

A tyre is a rubber covering for a wheel, providing traction, cushioning, and support.

• Tyres are made of rubber and are designed to fit around a wheel.

• They provide traction between the vehicle and the road surface.

• Tyres also act as a cushion, absorbing shocks and vibrations.

• They support the weight of the vehicle and help maintain stability.

• Different types of tyres are available for various vehicles and road conditions.

• Examples include summer tyres, winter tyres, all-season tyre...read more

Radial and Nylon are two types of tires used in vehicles.

• Radial tires have steel belts running perpendicular to the tread while Nylon tires have nylon cords running parallel to the tread.

• Radial tires provide better fuel efficiency and handling while Nylon tires offer better durability and resistance to punctures.

• Radial tires are more commonly used in passenger cars while Nylon tires are used in heavy-duty vehicles like trucks and buses.

There are mainly three types of tires: Bias ply, Radial ply, and Tubeless.

• Bias ply tires have a diagonal pattern and are cheaper than radial tires.

• Radial ply tires have a radial pattern and provide better handling and fuel efficiency.

• Tubeless tires do not require an inner tube and are puncture-resistant.

• Other types of tires include run-flat tires, all-terrain tires, and winter tires.

CPKM stands for Cost Per Thousand Kilometers. It is a metric used to measure the cost of transporting goods over a distance.

• CPKM is a financial metric commonly used in the transportation industry.

• It calculates the cost of transporting goods per thousand kilometers.

• CPKM helps companies analyze and compare the efficiency and profitability of their transportation operations.

• For example, if a company spends $10,000 to transport goods over 5,000 kilometers, the CPKM would be $2.
