The correct answer is:

D. The air particles increase their speed inside the tire because the temperature increases.

When a truck is driven, the friction from the road and the flexing of the tire walls generate heat, which increases the temperature of the air inside the tires. As the temperature of the air increases, the air particles move faster, leading to an increase in pressure according to the ideal gas law.
