Treadwear of 200 rating?

Question

How many miles will it last... say in normal combination city/highway driving.

Answer 1

Treadware Index
The number “200” in the example is the treadwear index. The tread of a tire with a treadwear index of 200 should last twice as long as one with a treadwear index of 100. The life of the “reference tire,” the one with an index of 100 to which all others are compared, is determined by convoys of 4 cars driving for 6,400 miles over public roads near San Angelo, Texas. Because tire life depends on many factors other than the tire, such as the weight of the vehicle, how it is driven, tire pressure, and so on, there is no accurate way of determining from the treadwear index how many miles you'll get. However, under the highly controlled test conditions, a tire with a treadwear index of 100 lasts for about 30,000 miles. In practice, treadwear indexes below 200 are low, over 400 high. Some tires with indexes in the 500s are available, while the special tires for the rear wheels of the Acura NSX are rated 120 (the rubber compounds that give the best traction also wear the fastest).

Answer 3

Not to long really (about 50,000 or less) that is a soft rubber compound!The higher the number the longer it will last!
