For answer  A 

The premature wear of the front tyres is caused, mainly, by the misalignment of the steering geometry. To extend the lifespan of the tyres, the periodic balancing of the wheels and their rotation (approximately at 10,000 - 20,000 km) is recommended, moving the wheels from the rear to the front and vice versa. Also, the tyre pressure must be checked at least monthly, when cold.

For answer  B 

The frequent driving with reduced speed does not lead to the premature wear of the tyres.

For answer  C 

The motor vehicles with traction on the rear axle (more precisely with propulsion on the rear axle, because the rear wheels push the motor vehicle, not pull it) will wear harder the tyres on the front axle, due to the propulsion force that creates stress only on the rear tyres, not also on the front ones, but neither these will wear prematurely the tyres, as long as the geometry is well adjusted and the tyre pressure is correct. 

The correct answer is: A
