Tread depth is important to monitor on your tyres to ensure that you are above the 4mm, where it is still safe to drive with them. If you go below 4 mm, key properties of the tyre will start deteriorating. It will not be safe to drive with those tyres, so you need to buy a new set. It is always safer to buy all four new tyres, as having different grip around the car can make the car less stable.
When you use worn-out tyres, you will lose stability on the road, causing the car to slide. Your braking distance will be extended, which will make you more likely to be in an accident. The braking distance is significantly increased when you go below the 4 mm.
The risk of aquaplaning will increase, as there is less volume in the grooves to channel away water to ensure contact between the tyre and the road surface. Aquaplaning can be very dangerous as you loose all control over your car. The control is often not regained before the car slows down enough to enable the grooves to push away the water. It might already be too late when this happens. Slow speed is always beneficial to avoid aquaplaning, but with newer tyres you don’t have to slow down as much.
When you change from your winter tyres to summer tyres, you want to make sure that you change to tyres that are safe to drive with. If the tyre station changes the tyres for you, they should check your tyres when they take them off to put on the summer tyres. They should at this point already inform you about the situation of your tyres. If they are very close to 4mm, you might as well change already at the start of the season to new ones, to save you the hassle to yet again have to go to the tyre station. The safety and avoiding hassle should be prioritized in this case.
Good tyres for the summer will make sure that you can drive safely, with good grip and stability. Even if you have heavy summer rain, good tyres should keep you safe and avoid aquaplaning. However, even with safe tyres, you need to drive cautiously and avoid distractions. Mobile phone while driving can be a very dangerous distraction.
