B. Tread depth above the level of built-in wear indicators
C. Low tire pressure
D. Tread depth below the level of built-in wear indicators

Answers

Answer:

Option D, Tread depth below the level of built-in wear indicators

Explanation:

The legal life of tire is checked by  looking out for tread wear indicators. In general, tread wear indicators are nothing but small bars of width of 5 mm. These bars are built in the main grooves of the tires.

If the tire tread is at the top level of the tread wear indicating bar, then it means that tires have reached the legal limit of tire death (1.6 mm)

Hence, option D is correct

When you accelerate, the size of the front tire patch becomes____

Answers

Answer:

Larger

Explanation:

When a vehicle is accelerated, the weight of the vehicle and the driver is transferred to the front of the  rear of the car.

This transferred weight is nothing but the  additional weight that presses the car's suspension in the downward direction thereby affecting tire contact patch in the rear due to which the rear tires loses adhesion.

When you accelerate, the size of the front tire patch becomes larger.

It should be noted that to develop the power to accelerate quickly, an internal combustion engine is vital. When a vehicle is accelerated, the weight of the vehicle and that of the driver will be transferred to the front of the vehicle.

Therefore, when you accelerate, the size of the front tire patch becomes larger since the transferred weight is additional weight.
