Some tires are not street legal because they lack the necessary design and construction to meet specific safety standards required for road use. Off-road tires, for example, may have aggressive tread patterns and softer compounds that are not suitable for pavement, leading to poor handling and increased wear on roads. Additionally, racing tires might offer fantastic performance on the track but fail to provide enough traction in wet conditions for daily driving. Manufacturers design these tires for specific conditions and explicitly state their intended use to ensure safety.
