The legal minimum tyre tread depth for cars is typically 1.6 millimetres across most countries, including the European Union and the United Kingdom, measured across the central portion of the tyre. In the United States, the standard is 2/32 of an inch, which is approximately equal to 1.6 millimetres. This limit ensures that tyres maintain sufficient grip on the road, especially in wet conditions, reducing the risk of skidding and accidents. Driving with tyres below the legal tread depth can result in fines, penalties, and increased safety risks.
