Can larger tires affect speedometer and odometer accuracy?

Larger tires can indeed affect speedometer and odometer accuracy. When the diameter of a tire increases, the distance that the vehicle travels with each rotation of the tire also increases. This means that when larger tires are installed, the speedometer will typically read a lower speed than the actual speed, and the odometer will underreport the distance traveled.

For instance, if a vehicle originally has smaller tires that are calibrated for a specific size, fitting larger tires means that the speedometer isn’t able to accurately measure the increased distance covered per tire revolution. This discrepancy is significant enough that it can lead to miscalculations in speed and distance, impacting driving safety and vehicle performance assessments.

Thus, the choice that states larger tires can indeed affect speedometer and odometer accuracy reflects the mechanical and mathematical relationship between tire size and the readings these instruments provide.
