Well I am suppose to get new tires in the morning, but before I do I was looking at the DOT stamp on the side wall of one of the tires. The DOT is showing 4603 for the last 4 on the rating. I know the tire was manufactured in the 46 week on the year 03. And since it is 08 that 5 years back. What is the opinions of some more experienced RV'ers on the tires , should I go ahead and get new ones or wait another year or so.
