When it comes to replacing your tyres, you need to keep your vehicle running smoothly. Tyres are important for steering, braking and handling but they also help you save fuel by reducing the rolling resistance on the road.
When you replace a single tyre, it is generally advised to replace all four at the same time to ensure balanced control across the vehicle and to prevent steering problems that could be dangerous to you and others on the road. However, you might be tempted to change just one at the time of replacement to save money.
Should You Change 2 Tyres at the Same Time?
Replacing only one tyre can be problematic, even if the remaining three are in good condition. This is because the new tyre will have a different tread depth than the rest tyre supplier, which can cause differences in the acceleration, braking and cornering abilities of your car as well as the impact on the electronic and mechanical systems in your car that interpret data from your tyres.
What is more, the uneven force exerted on the tyres can wear different parts of your axle system down to the point where they need replacing, which will usually be more expensive than changing just two tyres.
If you do decide to replace just one tyre at a time, it is recommended that you fit the new tyre on the rear of your vehicle so that it can provide more traction when driving on slick surfaces. This can reduce the risk of hydroplaning which can be dangerous when driving in heavy rain and helps prevent your vehicle from oversteering on slick roads.
