What is the treadwear index of Michelin Primacy 4?
2 Answers
Michelin Primacy 4 has a treadwear index of 400-500. Here is some relevant information about tires: Tire Introduction: Tires are the only components of a car that make contact with the ground. Some car owners only replace the tires on the drive wheels when changing tires. For example, some front-wheel-drive car owners only replace the two front tires, while some rear-wheel-drive car owners only replace the two rear tires. In fact, this practice is acceptable. Tire Aging: Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low during those four years. This is because tires can also age when left unused for extended periods, so it's important to check the production date when purchasing new tires.
I've used Michelin Primacy 4 tires, which have a treadwear rating of 280. This number indicates that under standardized testing, the tires can last approximately 2.8 times longer than the baseline value, meaning the tread remains in good condition even after tens of thousands of kilometers. The treadwear rating is based on tests conducted on wet roads and rough surfaces, and the Primacy 4 is designed to strike a balance in this regard, offering both strong grip and durability. However, actual wear depends on your driving habits—for example, frequent hard acceleration or driving on bumpy roads can reduce the rating faster. From my experience, maintaining proper tire pressure and practicing smooth driving can help extend the tire's lifespan, saving money on replacements. Overall, a rating of 280 is considered mid-to-high range, ideal for drivers looking for reliability and cost savings.
