How does a traction control system (ASR) basically work in a bus?

If the spinning wheel is braked, the differential directs the remaining drive torque from the engine to the wheel with traction. This allows starting and accelerating

If a wheel spins, the brake pedal must be pressed. This only brakes the spinning wheel

If both driven wheels of an axle spin, the engine drive torque is electronically reduced

If a wheel spins, the wheel brake there is electronically activated

The numbers 156 / 150 in the designation of your bus tires indicate the load capacity. How can you determine the maximum permissible load of this tire?

The number indicates the load capacity in encoded form. I can usually find the maximum permissible load in my bus operating manual

This results directly from the number. 156 means a maximum permissible load of 1560 kg

The number indicates the load capacity in encoded form. I can find the maximum permissible load on the internet

The number indicates the load capacity in encoded form. I can find the maximum permissible load in tables

You need to change a wheel on your bus of vehicle class M3. How can you safely carry out the wheel change?

I use a sufficiently dimensioned jack for lifting the bus

I use locking pliers for tightening the wheel nuts

I use a suitable wheel nut wrench with a sufficiently long lever arm for loosening and tightening the wheel nuts

I use a sufficiently long, suitable mounting bar for moving and levering the wheel onto the wheel carrier
