There is a simple way for checking to see if there is enough tread on your tyres. All passenger, light truck, and medium commercial tyres have tread wear indicator bars moulded into the tread. These bars are located at the bottoms of the tread grooves in several locations around the tyre, and when the tyre is worn to the point where any of them become visibly flushed with the adjacent tread ribs, it is time to replace the tyre.
If a tyre looks like this, it may be under inflated. The worst enemy a tyre can have is too little inflation pressure. Under inflation reduces treadlife through increased tread wear on the outside edges (or shoulders) of the tyre. It also generates excessive heat which reduces tyre durability. Finally, it reduces fuel economy through increased rolling resistance (soft tyres makes your vehicle work harder). Check your tires regularly for proper inflation. Abnormal tyre wear may also be due to misalignment or mechanical problems. Goodyear retailers can provide expert diagnosis and repair.
Wear In Center: OVER INFLATION
When a tyre is over inflated, the center of the tread bears most of the load and wears out faster than the outside edges. Uneven wear reduces the useful life of a tyre. Check your tyres regularly for proper inflation. Abnormal tyre wear may also be due to misalignment or mechanical problems. Goodyear retailers can provide expert diagnosis and repair.
Cups or Dips in the tread: WORN PARTS
Cupping (also called dipping or scalloping) is most common on front tyres, though rear tyres can cup as well. It may be a sign that wheels are out of balance or that suspension or steering system parts are worn out. Many Goodyear retailers can provide expert diagnosis and repair.
Sawtooth edges: MISALIGNMENT
Do the edges of the tread take on a sawtooth or feathered appearance? This is caused by erratic scrubbing against the road. The solution is toe-in or toe-out.
Proper tread depth is essential for proper tyre performance. If you notice a loss or change in wet traction, you may not have enough tread left on your tyres. Once the tread depth reaches 1/16th of an inch it must be replaced.
