No, the first two digits are the WEEK, not MONTH.

So, something like 3513.

0913 would be early March 2013 (9th week of 2013).

You are correct. I was wrong. I knew this, I must have had a mental lapse. Thank you for the correction! Tommy

I only run Michelin XRV tires so I would get a hold of a Michelin Rep. and seek there advice. I bought new tires in May and they had a May 2013 date stamp on them. Good Luck

Excellent question...and this will freak out most here but,this depends on how much the vehicle is used. If it is used moderately to little then the newer the better...if in continual use then the older the better. The only reason to buy the newest rubber possible is if the vehicle is used little and you want extended use time. However the fresher tires used on vehicles that are in constant use works against what performance one would want from their vehicle.

Newer tires will retain all of their elasticity, wasting available torque thereby reducing power and fuel miles...how much is determined by usage.

Where as older tires will have had time to dry out some and give better performance. The amounts are relative to the amount used...but if you think in terms of say putting 80 to 90 thousand miles on annually then the difference is significant.

As close to this month as possible. My max would be three months back. 0913. I hope this helps.

To make an accurate decision you really need to know when the factory made the last run of the brand, style, and size tires you are interested in. Contrary to popular belief most RV tires aren't made continually. They're usually made early in the year with the expectation that they will be to the tire dealers in time for the expected spring rush.

Additional runs will be made depending on the sales and inventory numbers. If sales are robust there could be several runs throughout the year. If sales are slow there may be only a single run. The last time we needed tires for our 2001 Adventurer we checked with a trusted dealer. They told us when the most current run had been made, and when the next run was scheduled. We decided to wait for the next run then ordered some. The tires we got were only 3 weeks old when they were installed.

What should be the oldest date code I should accept on new Class A tires in a December install?

Thanks!

The chassis may have been sitting on the coach builders lot for a couple years, so the tires may be that old.

113....Dennis

6-7 months but depends on price.If I cold save say 100$ per tire I would accept year old tires

6 months old or newer
