Knowing when to replace your tyres is critical for road safety. Here are the 7 key signs our mobile tyre fitters look for. 1. Tread depth below 1.6mm: The legal minimum in the UK is 1.6mm, but most experts recommend replacing at 3mm.
Use a 20p coin — if you can see the outer rim of the coin, your tread is too low. 2. Visible bulges or bubbles: These indicate internal structural damage and require immediate emergency tyre replacement. 3.
Cracks in the sidewall: Surface cracking suggests ageing or UV damage and can lead to a blowout. 4. Persistent slow punctures: If you're regularly adding air, the tyre may have a slow leak. 5.
Vibration while driving: Unusual vibrations can indicate imbalanced or damaged tyres. 6. Uneven wear: Patchy wear can mean wheel alignment or suspension issues — get this checked alongside mobile tyre fitting. 7.
Age over 5–6 years: Even tyres with good tread can degrade over time. If your tyres are over 6 years old, have them inspected by a mobile tyre fitter.
