Without it, your safety on the road will be compromised and you may not be able to brake, accelerate or corner properly. The tread grooves on your tyre help to evacuate the water from the contact patch between your tyre and the road surface so your car can grip the road properly. Without sufficient tread depth your tyres may not be able to cope properly and you face an increased risk of aquaplaning.
