Checking Tyre Tread
There is a simple way to check if there is enough tread on your tyres. All passenger tyres, light truck tyres, 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.
Wear On Both Edges: UNDER INFLATION
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 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.

When a tyre is over inflated, the centre 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.

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.

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.
