I have Mission tires. I check lug nut torque and tire pressue before each trip. I have aluminum wheels. Kept tires coveded when not in use.(But, I have been lacking on this since I got the RV Port). My Sunline has been from the eastern panhandle of West Virginia to: Pigeon Forge, TN (3 times), Wisconson Dells (1x), The Badlands, The Black Hills, then to Glacier Nat. Park, then eastward across US 2 into Mackinaw City, Michigan and then south back home. So, quite a few miles, and no problems. I just looked at my tires when I got home this evening, and tread all looks great, no sign of uneven wear. As of right now, I am planning to leave home on/around July 10th for AZ, UT and CO, and will do so with my Missions. I am sure I will need to replace them by the time I complete this proposed trip, "IF" not before. I will probably be near that "magical" number of about 20K on these tires by then.
