2014 COACHMEN PRISM Wheels Problems

WE HAD A FAILURE OF ONE OF THE REAR DUAL TIRES ON INTERSTATE 15 SOUTH OF IDAHO FALLS. THE MERCEDES SPRINTER 3500 CHASSIS AND CHROME REAR OUTSIDE DUAL WHEELS DOES NOT HAVE EFFECTIVE ACCESS TO THE DUAL TIRES TO CHECK AND CHANGE THE AIR PRESSURE. THE LENGTH OF THE INNER TIRE VALVE STEM MAKES THE JOB OF REINSTALLING THE VALVE CAP VIRTUALLY IMPOSSIBLE WITHOUT REMOVAL OF THE OUTER CHROME DUAL WHEEL. THE OUTSIDE DUAL IS ALMOST AS DIFFICULT. AS A RESULT, MOST OWNERS CAN NOT AND WILL NOT CHECK THE TIRE PRESSURE ON THE INNER DUAL TIRE CREATING A POTENTIAL SAFETY ISSUE. THE ONLY EFFECTIVE WAY TO CHECK TIRE PRESSURE IS TO REMOVE THE OUTER CHROME WHEEL A JOB THAT SHOULD ONLY BE DONE BY PROFESSIONALS WITH THE PROPER EQUIPMENT, NOT BY THE VEHICLE OWNER.
