Tow Master is what I have run since 2001 (single and tandem). We wear the tires out for the mileage before they have a chance to dry rot.
I actually overinflate by 5 - 10 lbs (less friction = less heat) and has worked for me. (They last about 5 yrs before replacing for us).
Before a long haul, I also jack them up and give them a spin to make sure there is no visible wobble (broken belt, bubble) and no friction/drag (wheel bearing or brake).
I think it also depends on the environment they are stored in as to how some areas have no issues and others do. (Cooler/cloudier PA weather vs Hot and Sunny AZ).
