Tires have to be exercised! With only 4400 miles, this MH has been parked A LOT! the tires do not get exercised while the coach is parked. As EVERYONE else has said, GET NEW TIRES NOW! These are a blowout or several just waiting to happen.
I have read several threads in the past where someone in a very similar situation had a blow out, got the tire replaced, drove down the road a couple hundred miles, had another blow out. Why would you ever want to chance it. The rot starts from the inside due to the lack of exercise.
