Technician A says a vehicle can be driven indefinitely on a high-pressure mini spare tire. Technician B says using a space saver spare tire can cause the ABS system to set a code. Who is correct?

Question

Quizplus · Accepted Answer

Technician B is correct because using a space saver spare tire, which is significantly smaller than the regular tires, can affect the ABS system's operation. The ABS system monitors the rotational speed of each wheel, and a smaller tire will rotate at a different speed, potentially causing the system to set a code due to the perceived discrepancy. Technician A is incorrect because high-pressure mini spare tires (also known as space saver or donut spares) are not designed for long-term use and can affect handling, fuel economy, and wear on the drivetrain if used indefinitely.
