What is a betterment?
A betterment is an additional amount that you may owe to the repair facility. This is normally assessed for parts that wear out in normal use, such as tires, batteries, convertible tops, etc. Your insurance company will determine how much of a parts life span has been used. For example, if your tire has 20% wear and a new tire cost $150, your insurance company may charge you betterment of $30.00, and they would pay $120 to replace the non-worn-out portion of the tire.
