Wondering if you can replace just one tyre to save money? This guide explains why tyre balance, tread depth, and axle pairing are crucial for safety and performance. Learn when it’s acceptable to replace a single tyre — and why replacing in pairs is usually the best choice for long-term value.
If you’re looking to keep the cost down when replacing tyres, you might be wondering if you can opt for a one-at-a-time approach. While there are several occasions when replacing just one tyre might seem like the best option – including when keeping costs down, and when replacing one damaged tyre as a result of a puncture – this is not recommended.
Why? Well, it all comes down to balance and safety.
What Happens if You Replace Just One Tyre?
If you opt for replacing one single tyre, then you will end up with a discrepancy in tread depth between two tyres that sit on the same axle.
If the front left tyre is a brand new replacement, but you leave an older front right tyre in place, the two will be unbalanced in tread depth and wear. This impacts the level of control you have over the vehicle and also means that actions like braking and accelerating will be performed at different speeds.
In short, the different levels of wear don’t just impact performance, but also the vehicle’s ability to respond to sudden braking or acceleration in a balanced way. It increases the risk of accidents and incidents on the road and makes for a more uncomfortable journey.
How Should You Replace Tyres?
Tyres should be replaced in pairs.
Because the front tyres wear at a quicker rate compared with those on the rear axle, most drivers will find that they can buy two replacements and perform a quick switch to prolong tyres’ lifespan.
Moving the existing rear tyres forwards, and fitting the new tyres to the rear axle, will maximise the lifespan of new tyres.
