Alphabet Codes on Tires: What Do They Mean? Tires have various markings that provide key information about their size, type, and performance. Here’s a breakdown of the most common letters found on tire sidewalls: • P: Passenger vehicle tire (e.g., P215/65R15). • LT: Light truck tire (e.g., LT235/75R15). • R: Radial construction (most modern tires). • M+S: Mud and Snow, suitable for mild off-road conditions. • XL: Extra load capacity, typically for heavier vehicles. Understanding these codes helps you select the right tire for your vehicle and driving conditions. #abcd #tires #tireinfo #tirecodes #carcare #vehiclesafety #tiremaintenance Mechanics Manual
