How to Repair Cracked Alloy Wheels

Previously alloy wheels were a luxury ‘add on’ but now they come as standard on most new models. Alloy wheels are a great accessory and make a statement on the road, but cracked alloys are an increasing problem for UK drivers.

What is a cracked alloy?

A cracked alloy wheel is when the alloy is showing visible cracks. Cracked alloys are commonly caused by kerbs, potholes or uneven roads. Cracked alloys are typically more serious than a scuffed alloy, but most cracks can be repaired by a professional.

It can be difficult to spot cracks in alloys, due to dirt and grime on the wheels. For car owners who want to keep their alloys in perfect condition, it is recommended that you clean your alloys regularly to check for any damage.

Why do alloy wheels crack?

Cracks in alloys are ultimately caused by impact. In most cases, a car’s wheels support around a tonne of metal, plastic and passengers on a daily basis. Plus, the wheels are under pressure from the tyres tightly wrapped around them. If the impact from a pothole for example is too great for the tyre to absorb, the impact will transmit to the wheel.

Extensive crack damage could cause the wheel to collapse, or to lose air pressure much quicker. Also, the steering may feel strange is the wheel is bent and cracked. As soon as you notice an alloy wheel crack, get it checked by a professional to avoid a sudden tyre failure. Even the smallest crack could result in a tyre blowout while driving.

Can alloy cracks be repaired at home?

The short is answer is probably not. There are however alloy wheel repair kits on the market, for minor damage such as a scratches or scuffs. Here is how to use an alloy repair kit and when not to.

The structural reliability of a car’s wheels is fundamental to its safety, so cracked alloy repairs are best left to the professionals.

How are cracked alloys repaired?
