Tires are a large part of the cost of ownership of an aerial lift. This is especially true on 4 wheel drive and larger lifts that require large or specialty tires. We replace or repair tires as needed on used equipment before sale. Our tire percentage is an estimate of remaining treadlife based on a scale of 0 to 100, with 100% being a new tire. The majority of our equipment will have tires with remaining treadlife of over 50%.
