The first set -Bridgestone BT020 lasted 9114 miles
The rear wore uneven - the front made lots of noise during the turns.
The second set - Avon Storms - lasted 7396 miles
Replaced both tires. Front still had 3000 to go.
The storms wore well - very smooth but poor mileage
The third set installed in 2009 were Dunlop Roadsmarts.
Will be replacing rear tire tomorrow. It has 7437 miles.
The face of the tire has the squared off center. It has just hit the wear bars.
The left side of the tire is almost worn smooth while the right side of the tire still have deep groves. Have attached pic's.
The front tire is almost perfect for wear and I will be leaving it on.
My next tire will be a Avon Storm 2
At least 99% of the mileage is with two up. We are fully loaded about half the time. I pray for the days when I can get over 10,000 miles on a rear tire.
