- Wear on both edges: UNDERINFLATION
Underinflation increases the tread wear on a tire’s outside edges and generates excessive heat reducing tire toughness. Soft tires also increases rolling resistance which reducing fuel economy.
- Wear in center: OVERINFLATION
Overinflation increases wear on the center tread.
- Cups or dips in the tread: WORN PARTS
Cupping or dipping is most common on front tires, although rear tires can cup as well.
- Sawtooth edges: MISALIGNMENT
Misalignment causes erratic scrubbing against the road giving the tire’s edges a saw tooth or feathered appearance.
