Treadwear, indicated by a number, represents the mileage of a tire in the same usage environment. The larger the number, the more wearresistant the tire is.
Here comes the tradeoff. Tires with excellent grip performance usually have a relatively lower treadwear index, which is why the treadwear index of highperformance tires is usually below 200. Tires with a treadwear index above 300 are usually more wearresistant, but their civilian and comfortable positioning makes their grip performance lower than that of highperformance tires with a competing and sporty positioning.
