Welcome to the forum --- feel free to join in the discussions and ask questions. In regards to the original '05 tires, I would seriously consider replacing them with a new set - especially if they are imports from China. There were, and still are, concerns about the quality of off-shore tires - especially around the early 2000's. In addition, these tires are also 7+ years old - depending upon the date of manufacture - and any tire of that age may not be safe - regardless of the amount of tread showing. As a rule of thumb, RV tires should be replaced after 5 years - or earlier - even if they look good. If it were my decision, I would be looking at a new set of good tires.
