When budgets are under pressure, part-worn tyres can appear to offer a simple way to reduce vehicle maintenance costs.
They are perfectly legal to sell and use in the UK, providing they meet the required safety and marking standards, but recent enforcement activity has highlighted a worrying question…
How confident can fleets and drivers really be about the condition of the part-worn tyres they are buying?
Inspections carried out over the past year have uncovered significant levels of non-compliance, including tyres with structural damage, exposed cords, poor repairs and other potentially dangerous defects.
For fleet operators, it is another reminder that when it comes to tyres, price should never be considered in isolation.
What Are The Risks With Part-Worn Tyres?
Perhaps the biggest challenge with any used tyre is that you don’t necessarily know its history.
A tyre may have plenty of visible tread remaining but could previously have suffered impact damage, been incorrectly repaired, driven while underinflated or subjected to loads that have affected its internal structure.
Some of those problems can be difficult to identify during a basic visual inspection and recent enforcement operations illustrate the scale of the potential problem.
During one inspection of 191 part-worn tyres being offered for sale, 36% were reportedly found to be in a dangerous condition, while only one met all of the required legal safety and marking standards.
In another operation, none of the 30 tyres inspected met the relevant legal requirements.
That does not mean every part-worn tyre is unsafe, but it does demonstrate why fleets need to think carefully about where tyres are sourced, and the processes used to check them.
Tyre Safety Is About More Than Tread Depth
We have talked before about the dangers associated with worn tyres, particularly as tread approaches the legal minimum of 1.6mm, but tread depth is only one part of tyre safety.
Damage to the sidewall, embedded objects, poor repairs, incorrect pressures and structural defects can all affect how a tyre performs, particularly during emergency braking or in wet conditions.
For fleets, that means tyre management cannot simply consist of checking whether a vehicle remains technically legal.
Regular inspections, clear replacement policies and effective defect-reporting procedures can all help identify problems earlier, while drivers also need to understand what they should be looking for during everyday vehicle checks.
There is also a financial consideration. A cheaper part-worn tyre with significantly less usable tread remaining may need replacing sooner, potentially reducing or even removing the initial saving.
What Does This Mean For Fleet Operators?
Ultimately, fleets cannot control the standards applied across the entire tyre market, but they can control the standards applied to their own vehicles.
That means having confidence in suppliers, ensuring tyres are inspected regularly and creating clear processes for drivers to report damage or deterioration before it becomes a more serious safety issue.
Because tyres remain the only point of contact between a vehicle and the road, even relatively small defects can have significant consequences when something goes wrong.
And while good tyre management is only one part of fleet safety, it is another area where having better visibility can make a real difference.
Driving Monitor’s Risk Monitor and Fleet Monitor help organisations maintain greater visibility over driver and vehicle risk, supporting a more proactive approach to keeping fleets safe, compliant and on the road.
