Why Mixing Different Tyre Brands Put a Vehicle in Danger

When one tyre on a vehicle needs replacing, many drivers would simply get a replacement for that single tyre. Doing so is fine, but a grave mistake that a majority of drivers make is buying tyres from a different brand to the one already fitted. This might be because the original brand is not available at the time, or because a different brand is cheaper, or just because they were not able to find the same size in the same brand. For many drivers, this decision can be quite simple, but it can cause the vehicle to face serious safety problems that many drivers are completely unaware of. Yes, tyre replacement is mandatory after a particular time, but interchanging them with different brands can affect the way the vehicle handles, brakes, and responds, which can be quite dangerous. This blog post explains in simple terms why drivers should never mix different tyre brands and how it can go wrong.


Different Brand Tyres Offering Different Performance

One of the most crucial things for drivers to understand is that, no matter if they have tyres of the same size, changing their brand can have a big influence on the vehicle's performance. Every tyre manufacturer makes tyres using different rubber compounds, tread patterns, and internal designs to make their tyres perform in a certain way. Hence, having two identical tyre sizes but getting them from different brands can change the way the vehicle will grip the road, its braking performance and how they will behave. If two tyres with performance gaps are fitted on the same axle, drivers will notice that they will have better grip on one side than the other. This can lead to an imbalance and might make the vehicle harder to control, especially when driving during times when drivers need to brake or steer hard to avoid an accident.


Impact on Braking Performance

As mentioned above, having tyres from different brands means a less efficient braking performance, especially if different ones are fitted to the same axle. As soon as the driver presses the brakes, the vehicle won’t be able to stop evenly to bring the vehicle to a complete halt and do a controlled stop. If drivers have fitted two tyres from different brands on the same axle, they will experience different grip levels. One side will grip better than the other when the brakes are applied, which can cause the vehicle to pull to one side sharply as the brakes are pressed. This can be quite frightening and a difficult condition to handle, especially during emergencies. This is another crucial reason for drivers to fit matching tyres on the same axle. This can ensure that the brakes work evenly on both sides, giving the driver the straight and predictable stopping performance, which will make a vehicle safer.


Issues With Handling When Cornering

Not having matching rims fitted on the same axle can cause issues during cornering. As a vehicle corners, the tyres fitted to the same axle require proper grip to ensure drivers have a balanced vehicle and keep the vehicle on course. But if any single tyre has a superior grip than the other one, because of their different brand and use of different rubber compounds, causing the vehicle to behave differently and unpredictably, causing the vehicle to push wide of the corner. The danger can increase if the vehicle is driven at a higher speed or when drivers change lanes during an emergency, because in such situations, drivers need the vehicle to respond predictably. Hence, fitting tyres from matching brands and rubber compounds on each axle can help drivers have a more consistent handling in every situation.


Causing Issues With the Vehicle’s Electronic System

The next part targeted because of not fitting the same tyres to a vehicle is on the vehicle’s electronic safety systems, like stability control and traction control. These systems are designed to help the driver maintain control of the vehicle when things go wrong. Such systems are connected to each wheel, which ensures quick adjustments to make the vehicle more stable. But if drivers fit mismatched tyres on the same axle, the different grip levels and rolling behaviour of the two Tyres Leicester can cause issues with the working of such systems. This can lead to it generating inaccurate data. In many cases, these systems might be active even when not required or not activated when there is a major need for them. Hence, drivers should ensure that they have fitted matching tyres to always have a reliable and consistent performance.


Conclusion

Mixing different tyre brands on the same vehicle might not feel like such a major issue, but this small decision can cause a vehicle to face serious safety risks. With the difference in grip, braking performance and handling, the vehicle won’t be as stable and predictable when driving, especially during emergencies. If drivers fit the same tyre brands that are made with the exact rubber compound, they will be able to have a consistent performance in all conditions. It also helps them have a more balanced braking, control and overall performance.
