Also keep in mind a person that puts 500 miles on there bike in one day is harder on the tire than a rider who puts 500 miles on there tire in a week . This is due to the sustained temp of the tire , short trips (under 50 miles ) the tire doesnt get to soft , flip side: long trips the tire gets soft and it starts to wear faster . Add a hot summer day to the equation and you'll see how I've had a pilot road last 5500 miles from commuting , and the same tire last 2500 miles from 4- 600 + mile days .
