Your Tyres Could Save Your Life – Are You Checking Them?

They're the only thing connecting your motorcycle to the road. Combined, both tyres provide a contact patch roughly the size of two credit cards. Every acceleration, corner, and emergency stop depends on those small patches of rubber doing their job.

Yet tyres are one of the most overlooked safety items on a motorcycle.

Even the most experienced rider can be caught out by tyres that are worn, damaged, or past their best.

As tyres age, the rubber gradually hardens and loses flexibility. This can reduce grip, particularly in wet conditions. Cracks can develop in the sidewalls, tread depth can become dangerously low, and the tyre's ability to disperse water decreases.

You might not notice these changes during a short ride to work, but when you need maximum grip during an emergency manoeuvre, that's when tyre condition really matters.

One of the most common misconceptions is that a tyre is fine as long as it still has plenty of tread left.

Not necessarily.

Motorcycle tyres age even if they're rarely used.

Look for the four-digit date code stamped into the tyre sidewall. For example:

2321

This means the tyre was manufactured in the 23rd week of 2021.

While there is no strict legal expiry date for motorcycle tyres in the UK, many manufacturers recommend careful inspection once tyres reach around five years old and replacement consideration as they get older, depending on storage conditions and use.

If you're buying a used motorcycle, always check the tyre age. You may be surprised to find tyres that look almost new but are many years old.

Inspect both sidewalls and the tread area for signs of cracking.

Small cracks can indicate that the rubber is drying out and losing its flexibility. Exposure to sunlight, weather, and long periods without use can all contribute to this.

If you notice significant cracking, it's worth seeking professional advice and considering replacement.

Check Your Tread Depth

The legal minimum tread depth for motorcycles over 50cc is:

1mm across at least three-quarters of the tread width, with visible tread on the remaining quarter.

However, waiting until your tyres reach the legal minimum isn't always the safest approach.

Grip, especially in wet conditions, starts to reduce well before the tyre becomes illegal.

Many riders choose to replace tyres before reaching the minimum limit to maintain the best possible performance.

Common signs include:

Uneven wear can affect handling and stability, particularly when cornering.

If something doesn't look right, get it checked.

Check Pressures Regularly

A tyre can look perfectly healthy but still be unsafe if it's running at the wrong pressure.

Make pressure checks part of your regular riding routine, not just something you do before a long trip. A Two-Minute Check Could Make All The Difference

It takes less than two minutes and could prevent a dangerous situation later down the road.

At One Split Second, we believe that motorcycle safety isn't about one big decision. It's about lots of small decisions made consistently.

Checking your tyres is one of the simplest and most important of them.

Because sometimes, the difference between staying upright and losing control comes down to one split second.
