Which of the following maintenance issues can be addressed by retreading old tire casings?

Retreading old tire casings primarily addresses the issue of tread wear replacement. When a tire becomes worn down, particularly in the tread area which directly impacts traction and handling, retreading allows the reuse of the existing tire casing by applying a new layer of tread material. This process not only extends the life of the tire but also maintains performance characteristics close to those of a new tire.

Tread wear is a common issue that affects the viability of a tire, and retreading provides a cost-effective solution for replacing the worn tread without the need for manufacturing a whole new tire. It’s especially valuable in commercial applications where tires experience significant wear but the structural integrity of the casing remains intact.

In contrast, casing reinforcement, tire size adjustments, and weight distribution are not primary concerns that retreading addresses. These factors involve either structural modifications or specific fitment changes rather than simply replacing the tread.
