Your safety and that of others may depend on the condition of your tyres. You must check that they're correctly inflated and have sufficient tread depth. The legal minimum tread depth for cars is 1.6 mm. This depth should be across the central three-quarters of the breadth of the tyre and around the entire circumference.
