If your tyres are wearing in the middle, it could mean your tyres are OVER inflated. Tire tread wear on the edges of a tire will typically indicate inflation pressures are lower than specified.

When a tire is under-inflate the contact patch grows and the load is carried by the outside edges of the patch. Tyres will start to wear out over time, but some factors can increase the wear.

Front tyres wear faster because of movement through steering and tyres on driven wheels will wear more quickly. High speed driving increases temperature and wear. Driving with an excess load. Tyres are made from rubber, Rubber is made by vulcanising natural latex with sulphur.

Exposure to ultra violet light and to ozone in the atmosphere cause the chemical bonds of the rubber to break apart and the tyres literally start to fall. Tires that show excessive wear on the sides or shoulders are often the result of underinflation. This is the opposite of a center rib wear.

As such, if there is not enough air pressure inside the tires, the tendency is for air to move towards the sides. Worn tyres are more prone to air leaking. This loss of pressure causes the tyre to become underinflated and so the rate of tyre wear increases. Underinflated tyres also affect steering and braking as well as increasing fuel costs.

In the case of a rear-wheel drive vehicle, there is a more balanced wear relationship between tyres on the front and rear axles.

With a front-wheel drive vehicle, the wear to the front tyres is increased by the steering forces exerted on the front. The increased risk of a blowout. A tyre with a small amount of tread reduces protection to the tire casing. Tyres will normally wear out before they become unserviceable due to ageing.

The amount of damage depends on the exposure and the severity of the weather. Saw tooth tyre wear, also known as tyre stepping, is another uneven tyre wear pattern. Tyres have distinctive tread patterns moulded into their surface to allow them to get extra grip on the road. Their tread gives them the ability to deal with all surfaces in all conditions.

The word tire is a short form of attire, from the idea that a wheel with a tire is a dressed wheel. Nevertheless, traditional publishers continued using tire. Tread is the rubber on the tyre that touches the road.

As you drive, the tread will wear down. Braking distance and vehicle control are impaired. These tyres are not safe for driving and must be replaced. UK tyre law states that the legal limit for minimum tyre tread depth is 1. Other manufacturers use their own tread wear indicators.

This one (above), for example, is on a Giant tyre. If you’ve skidded your bike it could be that the tread wear indicators are still intact but you’ve worn through the tread in another area.

All the others from that test have either been.
