All components of your machine are covered for non-commercial use for
five years from the date of purchase, but wheels are wear items which
are prorated just like car tires. For example, if a wheel only lasts 3 years,
you will receive 40% off the price of a new one. The warranty does not
cover cosmetic issues, normal wear, or misuse of the product. For
commercial use, the warranty period is one year.
