Magnet Autos of Liverpool recommend that you walk around your vehicle once a week to inspect your tyres. Some damage is caused by general wear and tear, but there can be other reasons for them to wear down. Here are some examples:
Under Inflation
This causes tyres to wear on the outer edges, leaving the middle tread area less worn. It can also cause the tyre liner to degrade.
Over Inflation
This causes the opposite of under-inflation, and causes the middle tread area to wear away far more quickly than the edges of the tread.
Mis-Alignment
This causes uneven and feathered wear on the tread, due to the tyres not being aligned properly. The tread wears progressively from one side to the other.
Camber Wear
Excessive wheel camber can cause a sloping wear pattern on the outer edge of the tread.
Illegal Wear
This occurs when a tyre has been used well after reaching the legal minimum pattern depth of 1.6mm across the central ¾ of the tread. A 'bald' tyre like this should never be used on a vehicle which is in use on the roads. It is a safety hazard which must be avoided.
End Of Life
This is simply when a tyre reaches the legal minimum tread depth, so needs to be removed and replaced.
Emergency Braking
Emergency braking can cause the ever familiar black tyre marks on our road, where you can see the amount of tyre rubber which has been scraped onto the road surface during the hard braking period:, many tyres simply deflate after this trauma.
Trauma
Sharp objects and glass can cause considerable damage to a tyre meaning that it must be replaced immediately.
Impact Damage
This is damage caused by an impact to the side of the tyre, driving into a rock or high kerb at speed can cause this damage, which looks like a bulge or an egg to the naked eye.
