Page 2 - Tyre Changers

Modern tyre changers offer a range of features to handle everything from low‑profile tyres to large tractor wheels. Understanding these options helps you match a machine to your workload and protect customer wheels.

Manual, electric and automatic options

• Manual changers – These are cost‑effective and portable but require significant physical effort, making them suitable for low‑volume or mobile work.
• Electric changers – Powered by motors, they don’t need an air compressor but may require specific electrical infrastructure. They handle specialised tyres with less operator effort.
• Automatic machines – These minimise manual labour and are ideal for run‑flat and low‑profile tyres, automating most of the mounting and demounting process.

Mounting styles and head designs

• Rim‑clamp changers secure the wheel by the rim with adjustable clamps, offering versatility for different wheel sizes.
• Centre‑post changers hold the wheel through the hub for delicate or high‑end wheels, reducing the risk of rim

A tyre changing machine removes and installs tyres on the rim, while a wheel balancer ensures that the assembly spins evenly without vibration. Both services are essential for safety and tyre longevity.

Why wheel balancing matters

After new tyres are installed, the wheel assembly must be balanced. Tyre manufacturers balance tyres during production, but final balancing is done once the tyre is mounted on the rim. Without balancing, tiny weight differences cause vibrations and uneven wear. Balanced wheels roll smoothly and keep the tread in contact with the road.

Tyre wear affects balance

Even after a wheel is balanced, normal tread wear and pressure changes can throw off the balance over time. Regular balancing—typically every 6,000 miles—extends tyre life and reduces vibration. Unbalanced wheels can skip or bounce, causing uneven tread wear and potentially leading to blowouts.

Signs of imbalance

Vibration at certain speeds, uneven tread wear or a steering wheel that shakes are common
