Motorhomes are heavily loaded "light trucks" Just sitting parked in the sun and weather, the tires deteriorate to where they become unsafe in four or more years time. Appearance of tires, i.e. tread depth, etc is meaningless. Sidewall cracks that are deeper than 1/16 inch indicate "time to replace". Better for tires if rig is driven for some distance (often) than left sitting in driveway for months at a time. Average RV mileage is only around 5000 miles per year
