When to Replace Tyres: Essential Safety Guide

Changing tyres when it is appropriate keeps you safe and legal. Tyre wear has several indicators. When you notice these, replace the tyres before they break. Professional Tyres Halesowen provides complete tyre inspections to identify worn-out tyres, damage and ancient wear that requires prompt replacement to ensure safety and performance.

Understanding Tread Wear Indicators

The tyres with the Tread Wear Indicator are new. Those are little raised bars in the major grooves all around the tyre. They are laid flat so that you can locate them with ease.  

When the tread is flat with the top of the indicator bar, the tyre has arrived at the legal minimum of 1.6 mm. It is then time to change the tyre. The indicators are a clear visual representation of the legal depth.  

The tyre has triangular shapes on the sidewall indicating the position of the TWI. They make you locate the correct locations with ease. Looking at those spots will tell you how the tread is faring in general.

Using the 20p Coin Test  

The 20p coin test is a simple method of examining tread depth without any special equipment. Insert a 20p coin in the grooves at various locations of the tyre. The outer edge of the coin measures approximately 1.6 mm.  

When the groove reveals an outer edge of the coin, the tread is at or below the lawful limit. Next, you should change the tyre immediately. Wearing the test at numerous points creates disparate wear.  

This is a basic exam which allows you to make frequent checks with no equipment. Close calls have better readings with a tread depth gauge. A professional check-up examines the hidden damage that you may not see on the exterior.

Sidewall and Shoulder Damage

When the sidewall of a tyre is torn, it should be replaced immediately, regardless of the amount of tread remaining. Tears, swellings, or ruptures in the sidewall are extremely perilous. These components are very forceful during driving and turning. Bulges indicate that the layers of the tyre have broken. This may lead to a blowout, particularly when using the motorway, so change it right away.

When you run over the curbs or potholes, you damage the shoulder, where the tread and sidewall meet. The professional will inform you whether you require a new tyre or if you should look at it.

Punctures and Penetrations

Depending on the locations of the damage, sharp objects could be fixed or require a new tyre. Repairs can be made to small holes less than 6mm in the main tread. The sidewall or shoulder has holes that require a new tyre.

In case a tyre is repaired more than twice or has a lot of punctures around it is better to change it. The excessive number of repairs compromises the tyre.

Do not leave any metal or other objects in the tyre until it is checked by a professional. Occasionally, the object may seal the hole and prevent deflation of the tyre. After a thorough removal, the technicians will be able to make correct decisions regarding whether to repair it or not.

Bead and Rim Damage

Any damage to the bead where the tyre fits to the rim prevents the tyre from fitting properly. This may lead to slow leaks or the tyre may slip off. The most frequent reason is incorrect installation of the tyre or a serious hit.

Bead chafer damage refers to the rim or fitting being bad. These strengthened sections prevent movement of the bead when in use. In case such damage occurs, the tyre has to be changed as it will not remain stuck to the rim.

Bead problems typically accompany damage to the rim caused by impacts. The rim is bent or rusted, which cannot support the seal of the tyre. The rim and the tyre could require replacement based on the extent of damage.

Age-Related Replacement

Tyres deteriorate with age regardless of the tread depth or mileage put upon them. Rubber compounds harden with age and give way to cracks, which make it less gripping and oily. Most manufacturers recommend replacement after a maximum of ten years, irrespective of how good it looks. 

Visual inspection of the cracking reveals its ageing signs in the tread grooves and sidewalls. This crazing indicates serious deterioration of the compounds and requires replacement. Tyres over seven years of age should be closely monitored for signs of ageing.

Most date codes on sidewalls indicate the manufacturing date, allowing for an age assessment. The four-digit code indicates the week and year of the tyre's manufacture. Old tyres should be replaced even if they have considerable tread remaining.
