I drive 80 miles a day, 5 days a week to work on great MD roads and through the District of Columbia where roads can be horrible. There is a large amount of construction and there are horrible potholes. Tire wear is all from this drive and weekend chores and road trips with some light off road on fire roads and National Park drives. Except for the tendency to hydroplane, I can't complain about the tires. Summer combined city/highway mileage (50/50) is about 29 mpg. I'm not a maintenance fanatic but I try to keep air in the tires.
