First off, WELCOME to the forum, and congratulations on your purchase of that new rig. We appreciate you taking the time to provide the year and size of your coach.
Look on the INSIDE of the tire wall. There should be a series of numbers stamped inside an oval. (see picture below) This is the date code. The first two numbers represent the WEEK the tires were made. The second two indicated the YEAR. So, 5107 would indicate the tires were made in the 51st week of 2007.
Once you have that information, please let us know that AND your tire size. We can then offer better guidance in keeping you safe and on the road...Dennis
