Good mileage for 2015. I didn't cycle much as my wife sprained her ankle and I had to do more in the morning than usual from Sept to Dec. For April to August I figure I did 2500 miles. Guess it is telling as my latest Vredestein Fortezza tires have lasted for 2015 and 2016 and they usually are good for up to 4000 miles. I usually replace them once a year when I get my first flat.
