Must Snow Tires Be of the Same Model? Introduction to Snow Tires: Winter tires are categorized into three types based on their anti-slip performance on roads: serrated surface tires, snow tires, and studded tires. Snow tires are designed for use in snowy conditions, featuring rubber with metal studs to enhance traction. They are commonly used in colder regions prone to snow accumulation during winter. Classification of Tires: Tires can be broadly classified into 8 categories according to vehicle type: PC - Passenger Car tires; LT - Light Truck tires; TB - Truck and Bus tires; AG - Agricultural Vehicle tires; OTR - Off-The-Road tires (for construction vehicles); ID - Industrial Vehicle tires; AC - Aircraft tires; MC - Motorcycle tires. Tire specifications are often represented by a set of numbers, where the first number indicates the tire section width and the second number denotes the rim diameter, both measured in inches.
As a veteran driver with thirty years of experience, I understand why you're concerned about whether snow tire models need to be identical. In reality, they don't have to be exactly the same model, but the size and specifications must match the original vehicle specifications, such as tire width, height, and diameter, as closely as possible. Otherwise, it can easily lead to inaccurate speedometer readings, steering wheel vibrations, or ABS system errors, compromising driving safety. I learned this the hard way—last winter, I opted for slightly larger snow tires to save money, only to find that braking distances increased on icy roads, nearly causing an accident. After checking the vehicle manual, I confirmed that the manufacturer's recommended parameters must be followed. Now, I always prioritize the same model—not only does it make driving more stable, but it also reduces unnecessary wear. If you're unsure, consult a local mechanic or browse car forums; there's plenty of practical advice from others who've faced similar situations. Remember, safety comes first—don't take unnecessary risks!
