Difference Between the part # AM3S331 and part # AM1ST79

Question:

Im looking for 3 new tires or wheels for my pop-up camper. Im looking for ST185/80D13 tires, which would be either the AM3S331 or the AM1ST79. What is the manufacture date on the tires you have in stock?

The difference between the part # AM3S331 and # AM1ST79 is that the # AM3S331 comes with a rim whereas the # AM1ST79 is just the tire. If you need a rim and have a 5 on 4-1/2 inch bolt pattern then go with the combo, if all you need is the tire then go with just the tire.

We sell quite a bit of these wheels and tires so I would hate to give you a date since we might have a new shipment in by the time you order.

Here's how to determine the date a tire was manufactured. The DOT number code will be stamped on one side of the tire, near the bead area. This tire identification number will start with the letters DOT, then the next two numbers or letters are the plant code where the tire was manufactured. The last four numbers represent the week and year the tire was built. For example, the numbers 0410 means the fourth week of 2010.
