What is odometer tempering

Odometer fraud is the disconnection, resetting, or alteration of a vehicle’s odometer with the intent to change the number of miles indicated. According to the Federal statute 49 U.S. Code § 32703, a person cannot “advertise for sale, sell, use, install, or have installed, a device that makes an odometer of a motor vehicle register a mileage different from the mileage the vehicle was driven, as registered by the odometer within the designed tolerance of the manufacturer of the odometer”. To put it simply, it is a crime. As usual, the causes are lessening insurance premiums and increasing market prices of pre-owned cars.

According to common misconceptions, mileage is the most important factor to determine the condition of the vehicle. Needles to say, it is one of the important criteria, but not the most important. There are lots of things to take into consideration. For example, how well it is maintained, what is the age or how well it performs generally.

Mileage is misleading – Causes

Causes of misleading mileage

What is the reason behind it? The most obvious reason is the broken odometer. It generally happens with analog odometers. It has plastic gears that may break. Anyone can easily fix it with the help of video tutorials. 

Be careful when you replace tires. Variable tire size is what greatly affects the miles displayed. No matter what you use, larger or smaller, the information will become misleading. The main reason why tires play the role is that your odometer is always calibrated to the size of stock tires. How does your odometer calculate traveled distance? In the front tires, there is a sensor. This sensor monitors the total revolutions made by your tires and then sends the signal to the ECU. So, larger tires mean that numbers add up faster on the odometer because they cover more distance with every revolution it makes. Bear in mind, that when you change them make sure that you recalibrated your odometer. 

The inaccuracy is usual when you use smaller tires. The only difference is that numbers are adding up slower. The point is that if you ignore it, you will get an inaccurate reading at any rate.
